Obstet Gynecol 2024 OBJECTIVE: To describe syphilis treatment status and prenatal care among people with syphilis during pregnancy to identify missed opportunities for preventing congenital syphilis. METHODS: Six jurisdictions that participated in SET-NET (Surveillance for Emerging Threats to Pregnant People and Infants Network) conducted enhanced surveillance among people with syphilis during pregnancy based on case investigations, medical records, and linkage of laboratory data with vital records. Unadjusted risk ratios (RRs) were used to compare demographic and clinical characteristics by syphilis stage (primary, secondary, or early latent vs late latent or unknown) and treatment status during pregnancy (adequate per the Centers for Disease Control and Prevention's "Sexually Transmitted Infections Treatment Guidelines, 2021" vs inadequate or not treated) and by prenatal care (timely: at least 30 days before pregnancy outcome; nontimely: less than 30 days before pregnancy outcome; and no prenatal care). RESULTS: As of September 15, 2023, of 1,476 people with syphilis during pregnancy, 855 (57.9%) were adequately treated and 621 (42.1%) were inadequately treated or not treated. Eighty-two percent of the cohort received timely prenatal care. Although those with nontimely or no prenatal care were more likely to receive inadequate or no treatment (RR 2.50, 95% CI, 2.17-2.88 and RR 2.73, 95% CI, 2.47-3.02, respectively), 32.1% of those with timely prenatal care were inadequately or not treated. Those with reported substance use or a history of homelessness were nearly twice as likely to receive inadequate or no treatment (RR 2.04, 95% CI, 1.82-2.28 and RR 1.83, 95% CI, 1.58-2.13, respectively). CONCLUSION: In this surveillance cohort, people without timely prenatal care had the highest risk for syphilis treatment inadequacy; however, almost a third of people who received timely prenatal care were not adequately treated. These findings underscore gaps in syphilis screening and treatment for pregnant people, especially those experiencing substance use and homelessness, and the need for systems-based interventions, such as treatment outside of traditional prenatal care settings. |

Reeves EL , Neelam V , Carlson JM , Olsen EO , Fox CJ , Woodworth KR , Nestoridi E , Mobley E , Montero Castro S , Dzimira P , Sokale A , Sizemore L , Hall AJ , Ellington S , Cohn A , Gilboa SM , Tong VT . Am J Obstet Gynecol MFM 2023 6 (2) 101265 ![]() BACKGROUND: SARS-CoV-2 infection in pregnancy is associated with an increased risk of adverse birth outcomes such as preterm birth, stillbirth, and maternal and infant complications. Previous research suggests an increased risk of severe COVID-19 illness and stillbirth in pregnant people during delta variant predominance in 2021; however, those studies did not assess timing of infection during pregnancy, and few of them described COVID-19 vaccination status. OBJECTIVE: Using a large population-based cohort, this study compared pregnancy and infant outcomes and described demographic and clinical characteristics of pregnant people with SARS-CoV-2 infection prior to and during the delta variant period. STUDY DESIGN: This retrospective cohort analysis included persons with confirmed SARS-CoV-2 infection in pregnancy from 6 US jurisdictions reporting to the Surveillance for Emerging Threats to Pregnant People and Infants Network. Data were collected through case reports of polymerase chain reaction-positive pregnant persons and linkages to birth certificates, fetal death records, and immunization records. We described clinical characteristics and compared frequency of spontaneous abortion (<20 weeks of gestation), stillbirth (≥20 weeks), preterm birth (<37 weeks), small for gestational age, and term infant neonatal intensive care unit admission between the time periods of pre-delta and delta variant predominance. Study time periods were determined by when variants constituted more than 50% of sequences isolated according to regional SARS-CoV-2 genomic surveillance data, with time periods defined for pre-delta (March 3, 2020-June 25, 2021) and Delta (June 26, 2021-December 25, 2021). Adjusted prevalence ratios were estimated for each outcome measure using Poisson regression and were adjusted for continuous maternal age, race and ethnicity, and insurance status at delivery. RESULTS: Among 57,563 pregnancy outcomes, 57,188 (99.3%) were liveborn infants, 65 (0.1%) were spontaneous abortions, and 310 (0.5%) were stillbirths. Most pregnant persons were unvaccinated at the time of SARS-CoV-2 infection, with a higher proportion in pre-delta (99.4%) than in the delta period (78.4%). Of those with infections during delta and who were previously vaccinated, the timing from last vaccination to infection was a median of 183 days. Compared to pre-delta, infections during delta were associated with a higher frequency of stillbirths (0.7% vs 0.4%; adjusted prevalence ratio, 1.55; 95% confidence interval, 1.14-2.09) and preterm births (12.8% vs 11.9%; adjusted prevalence ratio, 1.14; 95% confidence interval, 1.07-1.20). The delta period was associated with a lower frequency of neonatal intensive care unit admission (adjusted prevalence ratio, 0.74; 95% confidence interval, 0.67-0.82) than in the pre-delta period. During the delta period, infection during the third trimester was associated with a higher frequency of preterm birth (adjusted prevalence ratio, 1.41; 95% confidence interval, 1.28-1.56) and neonatal intensive care unit admission (adjusted prevalence ratio, 1.21; 95% confidence interval, 1.01-1.45) compared to the first and second trimester combined. CONCLUSION: In this US-based cohort of persons with SARS-CoV-2 infection in pregnancy, the majority were unvaccinated, and frequencies of stillbirth and preterm birth were higher during the delta variant predominance period than in the pre-delta period. During the delta period, frequency of preterm birth and neonatal intensive care unit admission was higher among infections occurring in the third trimester vs those earlier in pregnancy. These findings demonstrate population-level increases of adverse fetal and infant outcomes, specifically in the presence of a COVID-19 variant with more severe presentation. |

Emerg Infect Dis 2024 30 (1) 202-204 We describe hepatitis C testing of 47 (2%) of 2,266 children diagnosed with perinatal hepatitis C who were exposed during 2018-2020 in 7 jurisdictions in the United States. Expected frequency of perinatal transmission is 5.8%, indicating only one third of the cases in this cohort were reported to public health authorities. |
Risk factors for illness severity among pregnant women with confirmed SARS-CoV-2 infection – Surveillance for Emerging Threats to Mothers and Babies Network, 20 state, local, and territorial health departments, March 29, 2020 -January 8, 2021 (preprint)
Galang RR , Newton SM , Woodworth KR , Griffin I , Oduyebo T , Sancken CL , Olsen EO , Aveni K , Wingate H , Shephard H , Fussman C , Alaali ZS , Silcox K , Siebman S , Halai UA , Lopez CD , Lush M , Sokale A , Barton J , Chaudhary I , Patrick PH , Schlosser L , Reynolds B , Gaarenstroom N , Chicchelly S , Read JS , de Wilde L , Mbotha D , Azziz-Baumgartner E , Hall AJ , Tong VT , Ellington S , Gilboa SM . medRxiv 2021 2021.02.27.21252169 Background Pregnant women with coronavirus disease 2019 (COVID-19) are at increased risk for severe illness compared with nonpregnant women. Data to assess risk factors for illness severity among pregnant women with COVID-19 are limited. This study aimed to determine risk factors associated with COVID-19 illness severity among pregnant women with SARS-CoV-2 infection.Methods Pregnant women with SARS-CoV-2 infection confirmed by molecular testing were reported during March 29, 2020–January 8, 2021 through the Surveillance for Emerging Threats to Mothers and Babies Network (SET-NET). Criteria for illness severity (asymptomatic, mild, moderate-to-severe, or critical) were adapted from National Institutes of Health and World Health Organization criteria. Crude and adjusted risk ratios for moderate-to-severe or critical COVID-19 illness were calculated for selected demographic and clinical characteristics.Results Among 5,963 pregnant women with SARS-CoV-2 infection, moderate-to-severe or critical COVID-19 illness was associated with age 30–39 years, Black/Non-Hispanic race/ethnicity, healthcare occupation, pre-pregnancy obesity, chronic lung disease, chronic hypertension, cardiovascular disease, and pregestational diabetes mellitus. Risk of moderate-to-severe or critical illness increased with the number of underlying medical or pregnancy-related conditions.Conclusions Pregnant women with moderate-to-severe or critical COVID-19 illness were more likely to be older and have underlying medical conditions compared to pregnant women with asymptomatic infection or mild COVID-19 illness. This information might help pregnant women understand their risk for moderate-to-severe or critical COVID-19 illness and inform targeted public health messaging.Summary Among pregnant women with COVID-19, older age and underlying medical conditions were risk factors for increased illness severity. These findings can be used to inform pregnant women about their risk for severe COVID-19 illness and public health messaging.Competing Interest StatementThe authors have declared no competing interest.Clinical TrialThis activity was reviewed by CDC, determined to be a non-research, public health surveillance activity, and was conducted consistent with applicable federal law and CDC policy.Clinical Protocols https://www.ncbi.nlm.nih.gov/pmc/articles/PMC7643898/ Funding StatementThis study was performed as regular work of the Centers for Disease Control and Prevention.

SARS-CoV-2 During Omicron Variant Predominance Among Infants Born to People With SARS-CoV-2.
Gosdin L , Chang D , Olsen EO , Lewis EL , Wingate H , Ojo KD , Shephard H , Sokale A , Mobley EL , Delgado-López C , Hall AJ , Gilboa SM , Tong VT , Woodworth KR . Pediatrics 2023 151 (5) ![]() SARS-CoV-2, the virus that causes COVID-19, continues to evolve, resulting in variants with properties that can affect transmissibility and/or severity.1 The period of Omicron variant predominance has been associated with increased transmissibility but lower severity in the general population.2,3 However, studies have shown increases in hospitalizations among infants when comparing the period of Omicron predominance to previous periods.4,5 SARS-CoV-2 infection during pregnancy can impart anti–SARS-CoV-2 antibodies to infants, but antibody levels quickly wane during the first 6 months.6 Analyses of the pre-Omicron period showed low incidence of SARS-CoV-2 infection among infants aged 0 to 6 months born to people with SARS-CoV-2 infection during pregnancy.7 Infants 0 to 6 months are the only group with no COVID-19 vaccine authorized. Our objective was to understand the rates of SARS-CoV-2 infection before and during the period of Omicron variant predominance among infants born to people with infection during pregnancy and whether the period of maternal infection affects infant susceptibility. |
Substance use among persons with syphilis during pregnancy - Arizona and Georgia, 2018-2021
Carlson JM , Tannis A , Woodworth KR , Reynolds MR , Shinde N , Anderson B , Hobeheidar K , Praag A , Campbell K , Carpentieri C , Willabus T , Burkhardt E , Torrone E , O'Callaghan KP , Miele K , Meaney-Delman D , Gilboa SM , Olsen EO , Tong VT . MMWR Morb Mortal Wkly Rep 2023 72 (3) 63-67 Despite universal prenatal syphilis screening recommendations and availability of effective antibiotic treatment, syphilis prevalence during pregnancy and the incidence of congenital syphilis have continued to increase in the United States (1,2). Concurrent increases in methamphetamine, injection drug, and heroin use have been described in women with syphilis (3). CDC used data on births that occurred during January 1, 2018-December 31, 2021, from two states (Arizona and Georgia) that participate in the Surveillance for Emerging Threats to Pregnant People and Infants Network (SET-NET) to describe the prevalence of substance use among pregnant persons with syphilis by congenital syphilis pregnancy outcome (defined as delivery of a stillborn or live-born infant meeting the surveillance case definition for probable or confirmed congenital syphilis). The prevalence of substance use (e.g., tobacco, alcohol, cannabis, illicit use of opioids, and other illicit, nonprescription substances) in persons with a congenital syphilis pregnancy outcome (48.1%) was nearly double that among those with a noncongenital syphilis pregnancy outcome (24.6%). Persons with a congenital syphilis pregnancy outcome were six times as likely to report illicit use of opioids and four times as likely to report using other illicit, nonprescription substances during pregnancy than were persons with a noncongenital syphilis pregnancy outcome. Approximately one half of persons who used substances during pregnancy and had a congenital syphilis pregnancy outcome had late or no prenatal care. Tailored interventions should address barriers and facilitators to accessing screening and treatment for syphilis among persons who use substances. The need for syphilis screening and treatment should be addressed at any health care encounter during pregnancy, especially among persons who use substances. |

MMWR Morb Mortal Wkly Rep 2023 72 (1) 9-14 Monkeypox (mpox) cases in the 2022 outbreak have primarily occurred among adult gay, bisexual, and other men who have sex with men (MSM); however, other populations have also been affected (1). To date, data on mpox in cisgender women and pregnant persons have been limited. Understanding transmission in these populations is critical for mpox prevention. In addition, among pregnant persons, Monkeypox virus can be transmitted to the fetus during pregnancy or to the neonate through close contact during or after birth (2-5). Adverse pregnancy outcomes, including spontaneous abortion and stillbirth, have been reported in previous mpox outbreaks (3). During May 11-November 7, 2022, CDC and U.S. jurisdictional health departments identified mpox in 769 cisgender women aged ≥15 years, representing 2.7% of all reported mpox cases.(†) Among cases with available data, 44% occurred in cisgender women who were non-Hispanic Black or African American (Black), 25% who were non-Hispanic White (White), and 23% who were Hispanic or Latino (Hispanic). Among cisgender women with available data, 73% reported sexual activity or close intimate contact as the likely route of exposure, with mpox lesions most frequently reported on the legs, arms, and genitals. Twenty-three mpox cases were reported in persons who were pregnant or recently pregnant(§); all identified as cisgender women based on the mpox case report form.(¶) Four pregnant persons required hospitalization for mpox. Eleven pregnant persons received tecovirimat, and no adverse reactions were reported. Continued studies on mpox transmission risks in populations less commonly affected during the outbreak, including cisgender women and pregnant persons, are important to assess and understand the impact of mpox on sexual, reproductive, and overall health. |

Obstet Gynecol 2022 140 (6) 997-999 The incidence of hepatitis C virus (HCV) infection in reproductive-aged adults quadrupled during the past decade. Hepatitis C can progress to advanced liver disease and be transmitted perinatally. Highly effective curative hepatitis C treatment is available but is not recommended in pregnancy. Using the Surveillance for Emerging Threats to Mothers and Babies Network, we describe timing of positive RNA testing among pregnant people with HCV (HCV RNA detected during or within one year prior to pregnancy). Four US jurisdictions reported 1161 pregnancies during 2018-2021 among people with hepatitis C: 75.9% were multiparous; and 21.4% had their first peri-pregnancy HCV RNA detected prior to pregnancy, indicating potential missed treatment opportunities to improve maternal health and prevent perinatal transmission. |

Pediatrics 2022 150 (6) OBJECTIVES: To assess the 6-month incidence of laboratory-confirmed severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection, postnatal care, hospitalization, and mortality among infants born to people with laboratory-confirmed SARS-CoV-2 infection during pregnancy by timing of maternal infection. METHODS: Using a cohort of liveborn infants from pregnancies with SARS-CoV-2 infections in the year 2020 from 10 United States jurisdictions in the Surveillance for Emerging Threats to Mother and Babies Network, we describe weighted estimates of infant outcomes from birth through 6 months of age from electronic health and laboratory records. RESULTS: Of 6601 exposed infants with laboratory information through 6 months of age, 1.0% (95% confidence interval: 0.8-1.1) tested positive, 19.1% (17.5-20.6) tested negative, and 80.0% (78.4-81.6) were not known to be tested for SARS-CoV-2. Among those ≤14 days of age, SARS-CoV-2 infection occurred only with maternal infection ≤14 days before delivery. Of 3967 infants with medical record abstraction, breastmilk feeding initiation was lower when maternal infection occurred ≤14 days before delivery compared with >14 days (77.6% [72.5-82.6] versus 88.3% [84.7-92.0]). Six-month all-cause hospitalization was 4.1% (2.0-6.2). All-cause mortality was higher among infants born to people with infection ≤14 days (1.0% [0.4-1.6]) than >14 days (0.3% [0.1-0.5]) before delivery. CONCLUSIONS: Results are reassuring, with low incidences of most health outcomes examined. Incidence of infant SARS-CoV-2, breastmilk feeding initiation, and all-cause mortality differed by timing of maternal infection. Strategies to prevent infections and support pregnant people with coronavirus disease 2019 may improve infant outcomes. |
Breast Milk Feeding of Infants at Birth Among People With Confirmed SARS-CoV-2 Infection in Pregnancy: SET-NET, 5 States, March 29, 2020-December 31, 2020.

Am J Public Health 2022 112 S787-s796 Objectives. To describe prevalence of breast milk feeding among people with severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection during pregnancy and examine associations between breast milk feeding, timing of maternal infection before delivery, and rooming-in status during delivery hospitalization. Methods. We performed a retrospective cohort study using data from Massachusetts, Minnesota, Nebraska, Pennsylvania, and Tennessee of whether people with confirmed SARS-CoV-2 infection during pregnancy in 2020 initiated breast milk feeding at birth. Results. Among 11114 (weighted number) people with SARS-CoV-2 infection in pregnancy, 86.5% (95% confidence interval [CI]=82.4%, 87.6%) initiated breast milk feeding during birth hospitalization. People with infection within 14 days before delivery had significantly lower prevalence of breast milk feeding (adjusted prevalence ratio [APR]=0.88; 95% CI=0.83, 0.94) than did those with infection at least 14 days before delivery. When stratified by rooming-in status, the association between timing of infection and breast milk feeding remained only among infants who did not room in with their mother (APR=0.77; 95% CI=0.68, 0.88). Conclusions. Pregnant and postpartum people with SARS-CoV-2 infection should have access to lactation support and be advised about the importance of breast milk feeding and how to safely feed their infants in the same room.

Paediatr Perinat Epidemiol 2022 36 (4) 476-484 BACKGROUND: Multiple reports have described neonatal SARS-CoV-2 infection, including likely in utero transmission and early postnatal infection, but published estimates of neonatal infection range by geography and design type. OBJECTIVES: To describe maternal, pregnancy and neonatal characteristics among neonates born to people with SARS-CoV-2 infection during pregnancy by neonatal SARS-CoV-2 testing results. METHODS: Using aggregated data from the Surveillance for Emerging Threats to Mothers and Babies Network (SET-NET) describing infections from 20 January 2020 to 31 December 2020, we identified neonates who were (1) born to people who were SARS-CoV-2 positive by RT-PCR at any time during their pregnancy, and (2) tested for SARS-CoV-2 by RT-PCR during the birth hospitalisation. RESULTS: Among 28,771 neonates born to people with SARS-CoV-2 infection during pregnancy, 3816 (13%) underwent PCR testing and 138 neonates (3.6%) were PCR positive. Ninety-four per cent of neonates testing positive were born to people with infection identified ≤14 days of delivery. Neonatal SARS-CoV-2 infection was more frequent among neonates born preterm (5.7%) compared to term (3.4%). Neonates testing positive were born to both symptomatic and asymptomatic pregnant people. CONCLUSIONS: Jurisdictions reported SARS-CoV-2 RT-PCR results for only 13% of neonates known to be born to people with SARS-CoV-2 infection during pregnancy. These results provide evidence of neonatal infection identified through multi-state systematic surveillance data collection and describe characteristics of neonates with SARS-CoV-2 infection. While perinatal SARS-CoV-2 infection was uncommon among tested neonates born to people with SARS-CoV-2 infection during pregnancy, nearly all cases of tested neonatal infection occurred in pregnant people infected around the time of delivery and was more frequent among neonates born preterm. These findings support the recommendation for neonatal SARS-CoV-2 RT-PCR testing, especially for people with acute infection around the time of delivery. |
Risk factors for illness severity among pregnant women with confirmed SARS-CoV-2 infection - Surveillance for Emerging Threats to Mothers and Babies Network, 22 state, local, and territorial health departments, March 29, 2020 -March 5, 2021.

Clin Infect Dis 2021 73 S17-S23 BACKGROUND: Pregnant women with coronavirus disease 2019 (COVID-19) are at increased risk for severe illness compared with nonpregnant women. Data to assess risk factors for illness severity among pregnant women with COVID-19 are limited. This study aimed to determine risk factors associated with COVID-19 illness severity among pregnant women with SARS-CoV-2 infection. METHODS: Pregnant women with SARS-CoV-2 infection confirmed by molecular testing were reported during March 29, 2020-March 5, 2021 through the Surveillance for Emerging Threats to Mothers and Babies Network (SET-NET). Criteria for illness severity (asymptomatic, mild, moderate-to-severe, or critical) were adapted from National Institutes of Health and World Health Organization criteria. Crude and adjusted risk ratios for moderate-to-severe or critical COVID-19 illness were calculated for selected demographic and clinical characteristics. RESULTS: Among 7,950 pregnant women with SARS-CoV-2 infection, moderate-to-severe or critical COVID-19 illness was associated with age 25 years and older, healthcare occupation, pre-pregnancy obesity, chronic lung disease, chronic hypertension, and pregestational diabetes mellitus. Risk of moderate-to-severe or critical illness increased with the number of underlying medical or pregnancy-related conditions. CONCLUSIONS: Older age and having underlying medical conditions were associated with increased risk of moderate-to-severe or critical COVID-19 illness among pregnant women. This information might help pregnant women understand their risk for moderate-to-severe or critical COVID-19 illness and inform targeted public health messaging. |
Suspected nonfatal drug-related overdoses among youth in the US: 2016-2019
Roehler DR , Olsen EO , Mustaquim D , Vivolo-Kantor AM . Pediatrics 2020 147 (1) BACKGROUND AND OBJECTIVES: During the current drug overdose crisis, the United States is experiencing a significant number of overdose deaths, hospitalizations, and emergency department visits. Given the vulnerability of young persons to substance use, it is important to assess how this crisis affects the nation's youth. In this study, we investigate trends in suspected nonfatal drug-related overdoses (all-drugs, opioids, heroin, and stimulants) among youth using syndromic surveillance data from 2016 to 2019. METHODS: A retrospective analysis of emergency department syndromic surveillance data were used to detect quarterly trends in suspected drug overdoses from April 2016 through September 2019 among youth aged 0 to 10, 11 to 14, and 15 to 24 years. Syndrome definitions were developed using chief complaint free-text and discharge diagnosis codes to identify overdoses involving all-drugs, opioids, heroin, and stimulants. Pearson χ(2) tests detected quarter-to-quarter changes, and joinpoint regression analysis assessed trends over time. RESULTS: On average, there was a 2.0 increase for youth aged 0 to 10 years and a 2.3 increase for youth aged 11 to 14 years for suspected all-drug overdoses. Suspected heroin overdoses decreased by an average of 3.3 per quarter for youth aged 15 to 24 years. Among all age groups, suspected stimulant overdoses increased across the study period, 3.3 for 0 to 10-year-olds, 4.0 for 11- to 14-year-olds, and 2.3 for 15- to 24-year-olds. CONCLUSIONS: Suspected stimulant-involved drug overdoses appear to be rising among youth. These findings could inform targeted interventions, such as stimulant-focused prevention, and comprehensive approaches, including school-based prevention and other strategies to lower morbidity and mortality. |

MMWR Morb Mortal Wkly Rep 2020 69 (44) 1635-1640 Pregnant women with coronavirus disease 2019 (COVID-19) are at increased risk for severe illness and might be at risk for preterm birth (1-3). The full impact of infection with SARS-CoV-2, the virus that causes COVID-19, in pregnancy is unknown. Public health jurisdictions report information, including pregnancy status, on confirmed and probable COVID-19 cases to CDC through the National Notifiable Diseases Surveillance System.* Through the Surveillance for Emerging Threats to Mothers and Babies Network (SET-NET), 16 jurisdictions collected supplementary information on pregnancy and infant outcomes among 5,252 women with laboratory-confirmed SARS-CoV-2 infection reported during March 29-October 14, 2020. Among 3,912 live births with known gestational age, 12.9% were preterm (<37 weeks), higher than the reported 10.2% among the general U.S. population in 2019 (4). Among 610 infants (21.3%) with reported SARS-CoV-2 test results, perinatal infection was infrequent (2.6%) and occurred primarily among infants whose mother had SARS-CoV-2 infection identified within 1 week of delivery. Because the majority of pregnant women with COVID-19 reported thus far experienced infection in the third trimester, ongoing surveillance is needed to assess effects of infections in early pregnancy, as well the longer-term outcomes of exposed infants. These findings can inform neonatal testing recommendations, clinical practice, and public health action and can be used by health care providers to counsel pregnant women on the risks of SARS-CoV-2 infection, including preterm births. Pregnant women and their household members should follow recommended infection prevention measures, including wearing a mask, social distancing, and frequent handwashing when going out or interacting with others or if there is a person within the household who has had exposure to COVID-19.(†). |
Resurgent methamphetamine use at treatment admission in the United States, 2008-2017
Jones CM , Olsen EO , O'Donnell J , Mustaquim D . Am J Public Health 2020 110 (4) e1-e8 Objectives. To evaluate trends and correlates of methamphetamine use in the United States.Methods. Data are from 15 747 334 drug-related treatment admissions among persons aged 12 years or older in the 2008-2017 Treatment Episode Data Set. We analyzed trends and used multivariable logistic regression.Results. Methamphetamine-related admissions increased from 15.1% of drug-related treatment admissions in 2008 to 23.6% in 2017. Increases occurred among nearly all demographic groups. Methamphetamine injection increased from 17.5% of admissions in 2008 to 28.4% in 2017. Among methamphetamine-related admissions, heroin use increased from 5.3% of admissions in 2008 to 23.6% in 2017. Characteristics associated with increased odds of reporting methamphetamine use at admission included female sex; admissions aged 35 to 44 years; admissions in the Midwest, South, and West; unemployment; not in labor force; living dependent; living homeless; and having a referral from criminal justice, a health care provider, or other community treatment source.Conclusions. Treatment admissions involving methamphetamine use increased significantly over the past decade and appear to be linked to the ongoing opioid crisis in the United States. Efforts to mobilize public health prevention, treatment, and response strategies to address rising methamphetamine use and overdose are needed. (Am J Public Health.

Racial/ethnic and age group differences in opioid and synthetic opioid-involved overdose deaths among adults aged 18 years in metropolitan areas - United States, 2015-2017
Lippold KM , Jones CM , Olsen EO , Giroir BP . MMWR Morb Mortal Wkly Rep 2019 68 (43) 967-973 Among the 47,600 opioid-involved overdose deaths in the United States in 2017, 59.8% (28,466) involved synthetic opioids (1). Since 2013, synthetic opioids, particularly illicitly manufactured fentanyl (IMF), including fentanyl analogs, have been fueling the U.S. overdose epidemic (1,2). Although initially mixed with heroin, IMF is increasingly being found in supplies of cocaine, methamphetamine, and counterfeit prescription pills, which increases the number of populations at risk for an opioid-involved overdose (3,4). With the proliferation of IMF, opioid-involved overdose deaths have increased among minority populations including non-Hispanic blacks (blacks) and Hispanics, groups that have historically had low opioid-involved overdose death rates (5). In addition, metropolitan areas have experienced sharp increases in drug and opioid-involved overdose deaths since 2013 (6,7). This study analyzed changes in overdose death rates involving any opioid and synthetic opioids among persons aged >/=18 years during 2015-2017, by age and race/ethnicity across metropolitan areas. Nearly all racial/ethnic groups and age groups experienced increases in opioid-involved and synthetic opioid-involved overdose death rates, particularly blacks aged 45-54 years (from 19.3 to 41.9 per 100,000) and 55-64 years (from 21.8 to 42.7) in large central metro areas and non-Hispanic whites (whites) aged 25-34 years (from 36.9 to 58.3) in large fringe metro areas. Comprehensive and culturally tailored interventions are needed to address the rise in drug overdose deaths in all populations, including prevention strategies that address the risk factors for substance use across each racial/ethnic group, public health messaging to increase awareness about synthetic opioids in the drug supply, expansion of naloxone distribution for overdose reversal, and increased access to medication-assisted treatment. |
Notes from the field: Unintentional drug overdose deaths with kratom detected - 27 states, July 2016-December 2017
Olsen EO , O'Donnell J , Mattson CL , Schier JG , Wilson N . MMWR Morb Mortal Wkly Rep 2019 68 (14) 326-327 Kratom (Mitragyna speciosa), a plant native to Southeast Asia, contains the alkaloid mitragynine, which can produce stimulant effects in low doses and some opioid-like effects at higher doses when consumed (1). Use of kratom has recently increased in popularity in the United States, where it is usually marketed as a dietary or herbal supplement (1). Some studies suggest kratom has potential for dependence and abuse (1,2). As of April 2019, kratom was not scheduled as a controlled substance. However, since 2012, the Food and Drug Administration has taken a number of actions related to kratom, and in November 2017 issued a public health advisory*; in addition, the Drug Enforcement Administration has identified kratom as a drug of concern. During 2011–2017, the national poison center reporting database documented 1,807 calls concerning reported exposure to kratom (3). To assess the impact of kratom, CDC analyzed data from the State Unintentional Drug Overdose Reporting System (SUDORS). |
Physical and sexual teen dating violence victimization and sexual identity among U.S. high school students, 2015
Olsen EO , Vivolo-Kantor A , Kann L . J Interpers Violence 2017 35 886260517708757 Lesbian, gay, and bisexual (LGB) youth are at risk for many negative behaviors associated with teen dating violence victimization (TDVV). This study describes the prevalence of physical and sexual TDVV by sexual identity and quantifies the increased risk for TDVV among LGB youth compared with heterosexual youth. The participants for this study were students in Grades 9 to 12 participating in the 2015 national Youth Risk Behavior Survey (YRBS) who responded to questions ascertaining sexual identity and both physical and sexual TDVV. Data were analyzed by sexual identity, stratified by sex, and controlled for race/ethnicity and grade in school. Frequencies of physical and sexual TDVV and prevalence of TDVV from a combined TDVV measure were calculated. Associations between these behaviors and sexual identity were identified. Generally, LGB youth had greater prevalence and frequency of TDVV compared with heterosexual youth. Prevalence of TDVV within sexual identity subgroups further differed by sex. Students who were not sure of their sexual identity had the highest risk of most categories of TDVV when adjusting for sex, race/ethnicity, and grade in school. These results are the first to use a nationally representative sample to describe frequency of TDVV and to determine prevalence of a combined physical and sexual TDVV measure by sexual identity among youth. Schools, communities, and families can help prevent teen dating violence and ameliorate the potential impacts of these victimizations. |
Sexual identity, sex of sexual contacts, and health-related behaviors among students in grades 9-12 - United States and selected sites, 2015
Kann L , Olsen EO , McManus T , Harris WA , Shanklin SL , Flint KH , Queen B , Lowry R , Chyen D , Whittle L , Thornton J , Lim C , Yamakawa Y , Brener N , Zaza S . MMWR Surveill Summ 2016 65 (9) 1-202 PROBLEM: Sexual identity and sex of sexual contacts can both be used to identify sexual minority youth. Significant health disparities exist between sexual minority and nonsexual minority youth. However, not enough is known about health-related behaviors that contribute to negative health outcomes among sexual minority youth and how the prevalence of these health-related behaviors compare with the prevalence of health-related behaviors among nonsexual minorities. REPORTING PERIOD: September 2014-December 2015. DESCRIPTION OF THE SYSTEM: The Youth Risk Behavior Surveillance System (YRBSS) monitors six categories of priority health-related behaviors among youth and young adults: 1) behaviors that contribute to unintentional injuries and violence; 2) tobacco use; 3) alcohol and other drug use; 4) sexual behaviors related to unintended pregnancy and sexually transmitted infections, including human immunodeficiency virus infection; 5) unhealthy dietary behaviors; and 6) physical inactivity. In addition, YRBSS monitors the prevalence of obesity and asthma and other priority health-related behaviors. YRBSS includes a national school-based Youth Risk Behavior Survey (YRBS) conducted by CDC and state and large urban school district school-based YRBSs conducted by state and local education and health agencies. For the 2015 YRBSS cycle, a question to ascertain sexual identity and a question to ascertain sex of sexual contacts was added for the first time to the national YRBS questionnaire and to the standard YRBS questionnaire used by the states and large urban school districts as a starting point for their YRBS questionnaires. This report summarizes results for 118 health-related behaviors plus obesity, overweight, and asthma by sexual identity and sex of sexual contacts from the 2015 national survey, 25 state surveys, and 19 large urban school district surveys conducted among students in grades 9-12. RESULTS: Across the 18 violence-related risk behaviors nationwide, the prevalence of 16 was higher among gay, lesbian, and bisexual students than heterosexual students and the prevalence of 15 was higher among students who had sexual contact with only the same sex or with both sexes than students who had sexual contact with only the opposite sex. Across the 13 tobacco use-related risk behaviors, the prevalence of 11 was higher among gay, lesbian, and bisexual students than heterosexual students and the prevalence of 10 was higher among students who had sexual contact with only the same sex or with both sexes than students who had sexual contact with only the opposite sex. Similarly, across the 19 alcohol or other drug use-related risk behaviors, the prevalence of 18 was higher among gay, lesbian, and bisexual students than heterosexual students and the prevalence of 17 was higher among students who had sexual contact with only the same sex or with both sexes than students who had sexual contact with only the opposite sex. This pattern also was evident across the six sexual risk behaviors. The prevalence of five of these behaviors was higher among gay, lesbian, and bisexual students than heterosexual students and the prevalence of four was higher among students who had sexual contact with only the same sex or with both sexes than students who had sexual contact with only the opposite sex. No clear pattern of differences emerged for birth control use, dietary behaviors, and physical activity. INTERPRETATION: The majority of sexual minority students cope with the transition from childhood through adolescence to adulthood successfully and become healthy and productive adults. However, this report documents that sexual minority students have a higher prevalence of many health-risk behaviors compared with nonsexual minority students. PUBLIC HEALTH ACTION: To reduce the disparities in health-risk behaviors among sexual minority students, it is important to raise awareness of the problem; facilitate access to education, health care, and evidence-based interventions designed to address priority health-risk behaviors among sexual minority youth; and continue to implement YRBSS at the national, state, and large urban school district levels to document and monitor the effect of broad policy and programmatic interventions on the health-related behaviors of sexual minority youth. |
Associations of teen dating violence victimization with school violence and bullying among US high school students
Vivolo-Kantor AM , Olsen EO , Bacon S . J Sch Health 2016 86 (8) 620-7 BACKGROUND: Teen dating violence (TDV) negatively impacts health, mental and physical well-being, and school performance. METHODS: Data from a nationally representative sample of high school students participating in the Centers for Disease Control and Prevention (CDC)'s 2013 Youth Risk Behavior Survey (YRBS) are used to demonstrate associations of physical and sexual TDV with school violence-related experiences and behaviors, including bullying victimization. Bivariate and adjusted sex-stratified regressions assessed relationships between TDV and school violence-related experiences and behaviors. RESULTS: Compared to students not reporting TDV, those experiencing both physical and sexual TDV were more likely to report carrying a weapon at school, missing school because they felt unsafe, being threatened or injured with a weapon on school property, having a physical fight at school, and being bullied on school property. CONCLUSIONS: School-based prevention efforts should target multiple forms of violence. |
Youth risk behavior surveillance - United States, 2015
Kann L , McManus T , Harris WA , Shanklin SL , Flint KH , Hawkins J , Queen B , Lowry R , Olsen EO , Chyen D , Whittle L , Thornton J , Lim C , Yamakawa Y , Brener N , Zaza S . MMWR Surveill Summ 2016 65 (6) 1-174 PROBLEM: Priority health-risk behaviors contribute to the leading causes of morbidity and mortality among youth and adults. Population-based data on these behaviors at the national, state, and local levels can help monitor the effectiveness of public health interventions designed to protect and promote the health of youth nationwide. REPORTING PERIOD COVERED: September 2014-December 2015. DESCRIPTION OF THE SYSTEM: The Youth Risk Behavior Surveillance System (YRBSS) monitors six categories of priority health behaviors among youth and young adults: 1) behaviors that contribute to unintentional injuries and violence; 2) tobacco use; 3) alcohol and other drug use; 4) sexual behaviors related to unintended pregnancy and sexually transmitted infections (STIs), including human immunodeficiency virus (HIV) infection; 5) unhealthy dietary behaviors; and 6) physical inactivity. In addition, YRBSS monitors the prevalence of obesity and asthma and other priority health behaviors. YRBSS includes a national school-based Youth Risk Behavior Survey (YRBS) conducted by CDC and state and large urban school district school-based YRBSs conducted by state and local education and health agencies. This report summarizes results for 118 health behaviors plus obesity, overweight, and asthma from the 2015 national survey, 37 state surveys, and 19 large urban school district surveys conducted among students in grades 9-12. RESULTS: Results from the 2015 national YRBS indicated that many high school students are engaged in priority health-risk behaviors associated with the leading causes of death among persons aged 10-24 years in the United States. During the 30 days before the survey, 41.5% of high school students nationwide among the 61.3% who drove a car or other vehicle during the 30 days before the survey had texted or e-mailed while driving, 32.8% had drunk alcohol, and 21.7% had used marijuana. During the 12 months before the survey, 15.5% had been electronically bullied, 20.2% had been bullied on school property, and 8.6% had attempted suicide. Many high school students are engaged in sexual risk behaviors that relate to unintended pregnancies and STIs, including HIV infection. Nationwide, 41.2% of students had ever had sexual intercourse, 30.1% had had sexual intercourse during the 3 months before the survey (i.e., currently sexually active), and 11.5% had had sexual intercourse with four or more persons during their life. Among currently sexually active students, 56.9% had used a condom during their last sexual intercourse. Results from the 2015 national YRBS also indicated many high school students are engaged in behaviors associated with chronic diseases, such as cardiovascular disease, cancer, and diabetes. During the 30 days before the survey, 10.8% of high school students had smoked cigarettes and 7.3% had used smokeless tobacco. During the 7 days before the survey, 5.2% of high school students had not eaten fruit or drunk 100% fruit juices and 6.7% had not eaten vegetables. More than one third (41.7%) had played video or computer games or used a computer for something that was not school work for 3 or more hours per day on an average school day and 14.3% had not participated in at least 60 minutes of any kind of physical activity that increased their heart rate and made them breathe hard on at least 1 day during the 7 days before the survey. Further, 13.9% had obesity and 16.0% were overweight. INTERPRETATION: Many high school students engage in behaviors that place them at risk for the leading causes of morbidity and mortality. The prevalence of most health behaviors varies by sex, race/ethnicity, and grade and across states and large urban school districts. Long-term temporal changes also have occurred. Since the earliest year of data collection, the prevalence of most health-risk behaviors has decreased (e.g., riding with a driver who had been drinking alcohol, physical fighting, current cigarette use, current alcohol use, and current sexual activity), but the prevalence of other behaviors and health outcomes has not changed (e.g., suicide attempts treated by a doctor or nurse, smokeless tobacco use, having ever used marijuana, and attending physical education classes) or has increased (e.g., having not gone to school because of safety concerns, obesity, overweight, not eating vegetables, and not drinking milk). Monitoring emerging risk behaviors (e.g., texting and driving, bullying, and electronic vapor product use) is important to understand how they might vary over time. PUBLIC HEALTH ACTION: YRBSS data are used widely to compare the prevalence of health behaviors among subpopulations of students; assess trends in health behaviors over time; monitor progress toward achieving 21 national health objectives for Healthy People 2020 and one of the 26 leading health indicators; provide comparable state and large urban school district data; and help develop and evaluate school and community policies, programs, and practices designed to decrease health-risk behaviors and improve health outcomes among youth. |
Sleep duration and injury-related risk behaviors among high school students - United States, 2007-2013
Wheaton AG , Olsen EO , Miller GF , Croft JB . MMWR Morb Mortal Wkly Rep 2016 65 (13) 337-341 Insufficient sleep is common among high school students and has been associated with an increased risk for motor vehicle crashes, sports injuries, and occupational injuries. To evaluate the association between self-reported sleep duration on an average school night and several injury-related risk behaviors (infrequent bicycle helmet use, infrequent seatbelt use, riding with a driver who had been drinking, drinking and driving, and texting while driving) among U.S. high school students, CDC analyzed data from 50,370 high school students (grades 9-12) who participated in the national Youth Risk Behavior Surveys (YRBSs) in 2007, 2009, 2011, or 2013. The likelihood of each of the five risk behaviors was significantly higher for students who reported sleeping ≤7 hours on an average school night; infrequent seatbelt use, riding with a drinking driver, and drinking and driving were also more likely for students who reported sleeping ≥10 hours compared with 9 hours on an average school night. Although insufficient sleep directly contributes to injury risk, some of the increased risk associated with insufficient sleep might be caused by engaging in injury-related risk behaviors. Intervention efforts aimed at these behaviors might help reduce injuries resulting from sleepiness, as well as provide opportunities for increasing awareness of the importance of sleep. |
HIV-related risk behaviors among male high school students who had sexual contact with males - 17 large urban school districts, United States, 2009-2013
Kann L , Olsen EO , Kinchen S , Morris E , Wolitski RJ . MMWR Morb Mortal Wkly Rep 2016 65 (5) 106-9 Young persons aged 13-24 years accounted for an estimated 22% of all new diagnoses of human immunodeficiency virus (HIV) infection in the United States in 2014. Most new HIV diagnoses among youths occur among males who have sex with males (MSM). Among all MSM, young black MSM accounted for the largest number of new HIV diagnoses in 2014 (1). To determine whether the prevalence of HIV-related risk behaviors among black male high school students who had sexual contact with males differed from the prevalence among white and Hispanic male students who had sexual contact with males, potentially contributing to the racial/ethnic disparities in new HIV diagnoses, CDC analyzed data from Youth Risk Behavior Surveys conducted by 17 large urban school districts during 2009-2013. Although other studies have examined HIV-related risk behaviors among MSM (2,3), less is known about MSM aged <18 years. Black male students who had sexual contact with males had a lower or similar prevalence of most HIV-related risk behaviors than did white and Hispanic male students who had sexual contact with males. These findings highlight the need to increase access to effective HIV prevention strategies for all young MSM. |
HIV testing among US high school students and young adults
Van Handel M , Kann L , Olsen EO , Dietz P . Pediatrics 2016 137 (2) e20152700 BACKGROUND: We assessed HIV testing trends among high school students and young adults. METHODS: We analyzed National Youth Risk Behavior Survey (YRBS) and Behavioral Risk Factor Surveillance System (BRFSS) data to assess HIV testing prevalence among high school students and young adults aged 18 to 24, respectively. Logistic regression models for each sample stratified by gender and race/ethnicity were estimated to assess trends in the percentages ever tested, with year as a continuous linear variable. We report absolute differences in HIV testing prevalence and model results for 2005-2013 (YRBS) and 2011-2013 (BRFSS). RESULTS: During the study periods, an average of 22% of high school students (17% of male and 27% of female students) who ever had sexual intercourse and 33% of young adults reported ever being tested for HIV. Among high school students, no change was detected in HIV testing prevalence during 2005-2013, regardless of gender or race/ethnicity. Among young adult males, an average of 27% had ever been tested, and no significant changes were detected overall or by race/ethnicity during 2011-2013. Significant decreases in testing prevalence were detected during 2011-2013 among young adult females overall (from 42.4% to 39.5%), young adult white females (from 37.2% to 33.9%), and young adult black females (from 68.9% to 59.9%). CONCLUSIONS: HIV testing prevalence was low among high school students and young adults. No increase in testing among young adult males and decreased testing among young adult black females is concerning given their higher risk of HIV infection. |

The relationship between state policies for competitive foods and school nutrition practices in the United States
Merlo CL , Olsen EO , Galic M , Brener ND . Prev Chronic Dis 2014 11 E66 INTRODUCTION: Most students in grades kindergarten through 12 have access to foods and beverages during the school day outside the federal school meal programs, which are called competitive foods. At the time of this study, competitive foods were subject to minimal federal nutrition standards, but states could implement additional standards. Our analysis examined the association between school nutrition practices and alignment of state policies with Institute of Medicine recommendations (IOM Standards). METHODS: For this analysis we used data from the Centers for Disease Control and Prevention's (CDC's) report, Competitive Foods and Beverages in US Schools: A State Policy Analysis and CDC's 2010 School Health Profiles (Profiles) survey to examine descriptive associations between state policies for competitive foods and school nutrition practices. RESULTS: Access to chocolate candy, soda pop, sports drinks, and caffeinated foods or beverages was lower in schools in states with policies more closely aligned with IOM Standards. No association was found for access to fruits or nonfried vegetables. CONCLUSION: Schools in states with policies more closely aligned with the IOM Standards reported reduced access to less healthful competitive foods. Encouraging more schools to follow these standards will help create healthier school environments and may help promote healthy eating among US children. |
A comparison of fruit and vegetable intake estimates from three survey question sets to estimates from 24-hour dietary recall interviews
Eaton DK , Olsen EO , Brener ND , Scanlon KS , Kim SA , Demissie Z , Yaroch AL . J Acad Nutr Diet 2013 113 (9) 1165-74 BACKGROUND: Fruit and vegetable (F/V) intake surveillance can provide information critical to the design and evaluation of interventions and the assessment of progress toward national intake objectives. The CDC's Youth Risk Behavior Surveillance System (YRBSS) assesses F/V intake among high school students using six questions about the frequency of intake in times per day. It is not known whether F/V intake frequency in times per day can be used as a proxy for intake in servings per day. OBJECTIVE: To compare F/V intake estimates based on responses to three sets of survey questions, including the standard set of six YRBSS questions, with criterion F/V intake in servings per day based on data from 24-hour dietary recall interviews. PARTICIPANTS/SETTING: Study participants were 610 high school students who completed an in-class questionnaire and three telephone-administered 24-hour dietary recall interviews. The questionnaire asked students how many times they consumed 100% fruit juice and ate fruit, carrots, potatoes, green salad, and other vegetables during the "past 7 days" (set 1), the number of times they did so "yesterday" (set 2), and the number of cup-equivalents of fruits and vegetables they consumed per day (set 3). MAIN OUTCOME MEASURE: Mean estimated F/V intake either as "times/day" or "servings/day" and the percentage of students whose estimated F/V intake was ≥1, ≥2, and ≥3 times/day or servings/day. STATISTICAL ANALYSES PERFORMED: t tests and corrected Pearson correlations were used to compare F/V intake estimates based on survey question responses with estimates based on responses to the 24-hour dietary recall interviews. RESULTS: Mean F/V intake estimates (in times/day or servings/day) based on responses to all sets of survey questions were significantly more than servings/day estimates based on responses to the 24-hour dietary recall interviews, and the percentages of students meeting each intake cutpoint were also more. Of the three sets of survey questions, the standard YRBSS questions produced estimates and percentages that were most consistently closest to 24-hour dietary recall interview estimates. CONCLUSIONS: For brief self-administered questionnaires of high school students, the current YRBSS questions are recommended for monitoring F/V intake even though mean intake estimates in times/day will likely be higher than, and are not a proxy for, mean intake estimates in servings/day. |
Sexual identity, sex of sexual contacts, and health-risk behaviors among students in grades 9-12--youth risk behavior surveillance, selected sites, United States, 2001-2009
Kann L , Olsen EO , McManus T , Kinchen S , Chyen D , Harris WA , Wechsler H . MMWR Surveill Summ 2011 60 (7) 1-133 PROBLEM: Sexual minority youths are youths who identify themselves as gay or lesbian, bisexual, or unsure of their sexual identity or youths who have only had sexual contact with persons of the same sex or with both sexes. Population-based data on the health-risk behaviors practiced by sexual minority youths are needed at the state and local levels to most effectively monitor and ensure the effectiveness of public health interventions designed to address the needs of this population. REPORTING PERIOD COVERED: January 2001-June 2009. DESCRIPTION OF SYSTEM: The Youth Risk Behavior Surveillance System (YRBSS) monitors priority health-risk behaviors (behaviors that contribute to unintentional injuries, behaviors that contribute to violence, behaviors related to attempted suicide, tobacco use, alcohol use, other drug use, sexual behaviors, dietary behaviors, physical activity and sedentary behaviors, and weight management) and the prevalence of obesity and asthma among youths and young adults. YRBSS includes state and local school-based Youth Risk Behavior Surveys (YRBSs) conducted by state and local education and health agencies. This report summarizes results from YRBSs conducted during 2001-2009 in seven states and six large urban school districts that included questions on sexual identity (i.e., heterosexual, gay or lesbian, bisexual, or unsure), sex of sexual contacts (i.e., same sex only, opposite sex only, or both sexes), or both of these variables. The surveys were conducted among large population-based samples of public school students in grades 9-12. RESULTS: Across the nine sites that assessed sexual identity, the prevalence among gay or lesbian students was higher than the prevalence among heterosexual students for a median of 63.8% of all the risk behaviors measured, and the prevalence among bisexual students was higher than the prevalence among heterosexual students for a median of 76.0% of all the risk behaviors measured. In addition, the prevalence among gay or lesbian students was more likely to be higher than (rather than equal to or lower than) the prevalence among heterosexual students for behaviors in seven of the 10 risk behavior categories (behaviors that contribute to violence, behaviors related to attempted suicide, tobacco use, alcohol use, other drug use, sexual behaviors, and weight management). Similarly, the prevalence among bisexual students was more likely to be higher than (rather than equal to or lower than) the prevalence among heterosexual students for behaviors in eight of the 10 risk behavior categories (behaviors that contribute to unintentional injuries, behaviors that contribute to violence, behaviors related to attempted suicide, tobacco use, alcohol use, other drug use, sexual behaviors, and weight management). Across the 12 sites that assessed sex of sexual contacts, the prevalence among students who had sexual contact with both sexes was higher than the prevalence among students who only had sexual contact with the opposite sex for a median of 71.1% of all the risk behaviors measured, and the prevalence among students who only had sexual contact with the same sex was higher than the prevalence among students who only had sexual contact with the opposite sex for a median of 29.7% of all the risk behaviors measured. Furthermore, the prevalence among students who had sexual contact with both sexes was more likely to be higher than (rather than equal to or lower than) the prevalence among students who only had sexual contact with the opposite sex for behaviors in six of the 10 risk behavior categories (behaviors that contribute to violence, behaviors related to attempted suicide, tobacco use, alcohol use, other drug use, and weight management). The prevalence among students who only had sexual contact with the same sex was more likely to be higher than (rather than equal to or lower than) the prevalence among students who only had sexual contact with the opposite sex for behaviors in two risk behavior categories (behaviors related to attempted suicide and weight management). INTERPRETATIONS: Sexual minority students, particularly gay, lesbian, and bisexual students and students who had sexual contact with both sexes, are more likely to engage in health-risk behaviors than other students. PUBLIC HEALTH ACTION: Effective state and local public health and school health policies and practices should be developed to help reduce the prevalence of health-risk behaviors and improve health outcomes among sexual minority youths. In addition, more state and local surveys designed to monitor health-risk behaviors and selected health outcomes among population-based samples of students in grades 9-12 should include questions on sexual identity and sex of sexual contacts. |
Healthy people 2010 objectives for unintentional injury and violence among adolescents: trends from the National Youth Risk Behavior Survey, 1999-2009
Olsen EO , Hertz MF , Shults RA , Hamburger ME , Lowry R . Am J Prev Med 2011 41 (6) 551-8 BACKGROUND: In 2000, the USDHHS released Healthy People 2010 (HP2010), a series of disease prevention and health promotion objectives for the nation. Thirty-nine of these objectives were dedicated to injury prevention and six of these objectives related to adolescents, who were tracked through CDC's National Youth Risk Behavior Survey (YRBS). PURPOSE: This paper uses national YRBS data from 1999 to 2009 to analyze overall and subgroup trends and determine progress toward targets for the following HP2010 objectives: seatbelt use (HP2010 objective 15-19); motorcycle helmet use (15-21); riding with a driver who had been drinking alcohol (26-6); physical fighting (15-38); weapon carrying on school property (15-39); and suicide attempts requiring medical attention (18-2). METHODS: The CDC conducted the national YRBS biennially from 1999 to 2009 and used similar three-stage cluster-sample designs to obtain representative samples of high school students in the U.S. This study was conducted in 2010 and used linear and quadratic time variables simultaneously in logistic regression models while controlling for gender, race/ethnicity, and grade to test for secular trends over time. RESULTS: Only two objectives met their HP2010 targets: riding with a driver who had been drinking alcohol (26-6) and physical fighting (15-38). Progress was seen for four additional objectives and within some subgroups. CONCLUSIONS: Substantial policy and practice changes must occur if the recently released Healthy People 2020 targets are to be met. School-, community-, and state-level policies and programs may be effective tools to prevent injuries and victimizations. |
