HIV testing during pregnancy among women with a recent live birth-Seven US States, 2016-2019
Nwangwu-Ike N , Kapaya M , Oladapo K , DAngelo DV . Womens Health (Lond) 2023 19 17455057231199571 BACKGROUND: Although the United States has made progress in reducing the transmission of HIV from mother-to-child, it has not yet met the goal of reducing such transmissions to 70%. Self-reported HIV testing varied by state of residence. Approximately, two in three women reported that their health care provider asked them about HIV testing during prenatal care, and 82.3% of those asked reported receipt of a test. OBJECTIVES: The aim of this study was (1) to examine the prevalence of receipt of an HIV test during pregnancy and (2) to examine differences in HIV testing during pregnancy by race/ethnicity, state of residence, and other sociodemographic characteristics. DESIGN: Population-based surveillance of women with a recent live birth from seven US states. Individuals were sampled from birth certificate records 2-6 months postpartum and surveyed about their behaviors and experiences before, during, and shortly after pregnancy. METHODS: Data from the Pregnancy Risk Assessment Monitoring System, a large, population-based survey, were used to estimate the prevalence of HIV testing during pregnancy during 2016-2019. Weighted prevalence estimates and 95% confidence intervals were calculated overall and by demographic and other selected characteristics. RESULTS: Approximately two-thirds of women (66.1%) self-reported having a test for HIV during pregnancy. Prevalence varied by maternal characteristics and was highest among women who were non-Hispanic Black (80.7%) and among women who were aged ⩽ 24 years, had a high school education or less, were unmarried, or had Medicaid or no insurance for prenatal care (each > 70%). Self-reported HIV testing varied by state of residence. Approximately two in three women reported that their health care provider asked them about HIV testing during prenatal care, and 82.3% of those asked reported receipt of a test. CONCLUSION: About one in three Pregnancy Risk Assessment Monitoring System respondents did not report an HIV test during pregnancy. Health care providers can help educate pregnant patients about the importance of HIV testing and ensure universal testing to help identify individuals needing treatment and reduce the rates of mother-to-child HIV transmission. |
Prevalence of experiencing physical, emotional, and sexual violence by a current intimate partner during pregnancy: Population-based estimates from the Pregnancy Risk Assessment Monitoring System
D’Angelo DV , Bombard JM , Lee RD , Kortsmit K , Kapaya M , Fasula A . J Fam Violence 2022 38 (1) 117-126 Intimate partner violence (IPV) during pregnancy presents a risk for maternal mental health problems, preterm birth, and having a low birthweight infant. We assessed the prevalence of self-reported physical, emotional, and sexual violence during pregnancy by a current partner among women with a recent live birth. We analyzed data from the 2016–2018 Pregnancy Risk Assessment Monitoring System in six states to calculate weighted prevalence estimates and 95% confidence intervals for experiences of violence by demographic characteristics, health care utilization, and selected risk factors. Overall, 5.7% of women reported any type of violence during pregnancy. Emotional violence was most prevalent (5.4%), followed by physical violence (1.5%), and sexual violence (0.9%). Among women who reported any violence, 67.6% reported one type of violence, 26.5% reported two types, and 6.0% reported three types. Reporting any violence was highest among women using marijuana or illicit substances, experiencing pre-pregnancy physical violence, reporting depression, reporting an unwanted pregnancy, and experiencing relationship problems such as getting divorced, separated, or arguing frequently with their partner. There was no difference in report of discussions with prenatal care providers by experience of violence. The majority of women did not report experiencing violence, however among those who did emotional violence was most frequently reported. Assessment for IPV is important, and health care providers can play an important role in screening. Coordinated prevention efforts to reduce the occurrence of IPV and community-wide resources are needed to ensure that pregnant women receive needed services and protection. © 2022, This is a U.S. government work and not under copyright protection in the U.S.; foreign copyright protection may apply. |
Pregnancy Risk Assessment Monitoring System for Dads: A piloted randomized trial of public health surveillance of recent fathers' behaviors before and after infant birth
Garfield CF , Simon CD , Stephens F , Castro Román P , Bryan M , Smith RA , Kortsmit K , Salvesen von Essen B , Williams L , Kapaya M , Dieke A , Barfield W , Warner L . PLoS One 2022 17 (1) e0262366 BACKGROUND: Becoming a father impacts men's health and wellbeing, while also contributing to the health and wellbeing of mothers and children. There is no large-scale, public health surveillance system aimed at understanding the health and behaviors of men transitioning into fatherhood. The purpose of this study was to describe piloted randomized approaches of a state-based surveillance system examining paternal behaviors before and after their infant's birth to better understand the health needs of men and their families during the transition to parenthood. METHODS: During October 2018-July 2019, 857 fathers in Georgia were sampled 2-6 months after their infant's birth from birth certificates files and surveyed via mail, online or telephone, in English or Spanish, using two randomized approaches: Indirect-to-Dads and Direct-to-Dads. Survey topics included mental and physical health, healthcare, substance use, and contraceptive use. FINDINGS: Weighted response rates (Indirect-to-Dads, 33%; Direct-to-Dads, 31%) and population demographics did not differ by approach. Respondents completed the survey by mail (58%), online (28%) or telephone (14%). Among 266 fathers completing the survey, 55% had a primary care physician, and 49% attended a healthcare visit for themselves during their infant's mother's pregnancy or since their infant's birth. Most fathers were overweight or had obesity (70%) while fewer reported smoking cigarettes (19%), binge drinking (13%) or depressive symptoms (10%) since their infant's birth. CONCLUSIONS: This study tests a novel approach for obtaining population-based estimates of fathers' perinatal health behaviors, with comparable response rates from two pragmatic approaches. The pilot study results quantify a number of public health needs related to fathers' health and healthcare access. |
First 100 Persons with COVID-19 - Zambia, March 18-April 28, 2020.
Chipimo PJ , Barradas DT , Kayeyi N , Zulu PM , Muzala K , Mazaba ML , Hamoonga R , Musonda K , Monze M , Kapata N , Sinyange N , Simwaba D , Kapaya F , Mulenga L , Chanda D , Malambo W , Ngosa W , Hines J , Yingst S , Agolory S , Mukonka V . MMWR Morb Mortal Wkly Rep 2020 69 (42) 1547-1548 Zambia is a landlocked, lower-middle income country in southern Africa, with a population of 17 million (1). The first known cases of coronavirus disease 2019 (COVID-19) in Zambia occurred in a married couple who had traveled to France and were subject to port-of-entry surveillance and subsequent remote monitoring of travelers with a history of international travel for 14 days after arrival. They were identified as having suspected cases on March 18, 2020, and tested for COVID-19 after developing respiratory symptoms during the 14-day monitoring period. In March 2020, the Zambia National Public Health Institute (ZNPHI) defined a suspected case of COVID-19 as 1) an acute respiratory illness in a person with a history of international travel during the 14 days preceding symptom onset; or 2) acute respiratory illness in a person with a history of contact with a person with laboratory-confirmed COVID-19 in the 14 days preceding symptom onset; or 3) severe acute respiratory illness requiring hospitalization; or 4) being a household or close contact of a patient with laboratory-confirmed COVID-19. This definition was adapted from World Health Organization (WHO) interim guidance issued March 20, 2020, on global surveillance for COVID-19 (2) to also include asymptomatic contacts of persons with confirmed COVID-19. Persons with suspected COVID-19 were identified through various mechanisms, including port-of-entry surveillance, contact tracing, health care worker (HCW) testing, facility-based inpatient screening, community-based screening, and calls from the public into a national hotline administered by the Disaster Management and Mitigation Unit and ZNPHI. Port-of-entry surveillance included an arrival screen consisting of a temperature scan, report of symptoms during the preceding 14 days, and collection of a history of travel and contact with persons with confirmed COVID-19 in the 14 days before arrival in Zambia, followed by daily remote telephone monitoring for 14 days. Travelers were tested for SARS-CoV-2, the virus that causes COVID-19, if they were symptomatic upon arrival or developed symptoms during the 14-day monitoring period. Persons with suspected COVID-19 were tested as soon as possible after evaluation for respiratory symptoms or within 7 days of last known exposure (i.e., travel or contact with a confirmed case). All COVID-19 diagnoses were confirmed using real-time reverse transcription-polymerase chain reaction (RT-PCR) testing (SARS-CoV-2 Nucleic Acid Detection Kit, Maccura) of nasopharyngeal specimens; all patients with confirmed COVID-19 were admitted into institutional isolation at the time of laboratory confirmation, which was generally within 36 hours. COVID-19 patients were deemed recovered and released from isolation after two consecutive PCR-negative test results ≥24 hours apart. A Ministry of Health memorandum was released on April 13, 2020, mandating testing in public facilities of 1) all persons admitted to medical and pediatric wards regardless of symptoms; 2) all patients being admitted to surgical and obstetric wards, regardless of symptoms; 3) any outpatient with fever, cough, or shortness of breath; and 4) any facility or community death in a person with respiratory symptoms, and 5) biweekly screening of all HCWs in isolation centers and health facilities where persons with COVID-19 had been evaluated. This report describes the first 100 COVID-19 cases reported in Zambia, during March 18-April 28, 2020. |
Risk factors for epidemic cholera in Lusaka, Zambia-2017
Nanzaluka FH , Davis WW , Mutale L , Kapaya F , Sakubita P , Langa N , Gama A , N'Cho H S , Malambo W , Murphy J , Blackstock A , Mintz E , Riggs M , Mukonka V , Sinyange N , Yard E , Brunkard J . Am J Trop Med Hyg 2020 103 (2) 646-651 On October 6, 2017, the Zambia Ministry of Health declared a cholera outbreak in Lusaka. By December, 1,462 cases and 38 deaths had occurred (case fatality rate, 2.6%). We conducted a case-control study to identify risk factors and inform interventions. A case was any person with acute watery diarrhea (>/= 3 loose stools in 24 hours) admitted to a cholera treatment center in Lusaka from December 16 to 21, 2017. Controls were neighbors without diarrhea during the same time period. Up to two controls were matched to each case by age-group (1-4, 5-17, and >/= 18 years) and neighborhood. Surveyors interviewed cases and controls, tested free chlorine residual (FCR) in stored water, and observed the presence of soap in the home. Conditional logistic regression was used to generate matched odds ratios (mORs) based on subdistricts and age-groups with 95% CIs. We enrolled 82 cases and 132 controls. Stored water in 71% of case homes had an FCR > 0.2 mg/L. In multivariable analyses, those who drank borehole water (mOR = 2.4, CI: 1.1-5.6), had close contact with a cholera case (mOR = 6.2, CI: 2.5-15), and were male (mOR = 2.5, CI: 1.4-5.0) had higher odds of being a cholera case than their matched controls. The use of groundwater for drinking, contact with a cholera case, and male gender were associated with cholera. Based on these findings, we recommended health education about household water chlorination and hygiene in the home. Emergency responses included providing chlorinated water through emergency tanks and maintaining adequate FCR levels through close monitoring of water sources. |

Williams L , D'Angelo DV , Bauman B , Dieke AC , Ellington SR , Shapiro-Mendoza CK , Cox S , Hastings P , Shulman H , Harrison L , Kapaya M , Barfield WD , Warner L . Emerg Infect Dis 2020 26 (5) 998-1001 We surveyed women with a recent live birth who resided in 16 US states and 1 city during the 2016 Zika outbreak. We found high awareness about the risk of Zika virus infection during pregnancy and about advisories to avoid travel to affected areas but moderate levels of discussions with healthcare providers. |
Paternal involvement and maternal perinatal behaviors: Pregnancy Risk Assessment Monitoring System, 2012-2015
Kortsmit K , Garfield C , Smith RA , Boulet S , Simon C , Pazol K , Kapaya M , Harrison L , Barfield W , Warner L . Public Health Rep 2020 135 (2) 253-261 OBJECTIVES: Paternal involvement is associated with improved infant and maternal outcomes. We compared maternal behaviors associated with infant morbidity and mortality among married women, unmarried women with an acknowledgment of paternity (AOP; a proxy for paternal involvement) signed in the hospital, and unmarried women without an AOP in a representative sample of mothers in the United States from 32 sites. METHODS: We analyzed 2012-2015 data from the Pregnancy Risk Assessment Monitoring System, which collects site-specific, population-based data on preconception, prenatal and postpartum behaviors, and experiences from women with a recent live birth. We calculated adjusted prevalence ratios (aPRs) and 95% confidence intervals (CIs) to examine associations between level of paternal involvement and maternal perinatal behaviors. RESULTS: Of 113 020 respondents (weighted N = 6 159 027), 61.5% were married, 27.4% were unmarried with an AOP, and 11.1% were unmarried without an AOP. Compared with married women and unmarried women with an AOP, unmarried women without an AOP were less likely to initiate prenatal care during the first trimester (married, aPR [95% CI], 0.94 [0.92-0.95]; unmarried with AOP, 0.97 [0.95-0.98]), ever breastfeed (married, 0.89 [0.87-0.90]; unmarried with AOP, 0.95 [0.94-0.97]), and breastfeed at least 8 weeks (married, 0.76 [0.74-0.79]; unmarried with AOP, 0.93 [0.90-0.96]) and were more likely to use alcohol during pregnancy (married, 1.20 [1.05-1.37]; unmarried with AOP, 1.21 [1.06-1.39]) and smoke during pregnancy (married, 3.18 [2.90-3.49]; unmarried with AOP, 1.23 [1.15-1.32]) and after pregnancy (married, 2.93 [2.72-3.15]; unmarried with AOP, 1.17 [1.10-1.23]). CONCLUSIONS: Use of information on the AOP in addition to marital status provides a better understanding of factors that affect maternal behaviors. |
Risk and protective factors for cholera deaths during an urban outbreak - Lusaka, Zambia, 2017-2018
Mutale LS , Winstead AV , Sakubita P , Kapaya F , Nyimbili S , Mulambya NL , Nanzaluka FH , Gama A , Mwale V , Kim S , Ngosa W , Yard E , Sinyange N , Mintz E , Brunkard J , Mukonka V . Am J Trop Med Hyg 2020 102 (3) 534-540 The Republic of Zambia declared a cholera outbreak in Lusaka, the capital, on October 6, 2017. By mid-December, 20 of 661 reported cases had died (case fatality rate 3%), prompting the CDC and the Zambian Ministry of Health through the Zambia National Public Health Institute to investigate risk factors for cholera mortality. We conducted a study of cases (cholera deaths from October 2017 to January 2018) matched by age-group and onset date to controls (persons admitted to a cholera treatment center [CTC] and discharged alive). A questionnaire was administered to each survivor (or relative) and to a family member of each decedent. We used univariable exact conditional logistic regression to calculate matched odds ratios (mORs) and 95% CIs. In the analysis, 38 decedents and 76 survivors were included. Median ages for decedents and survivors were 38 (range: 0.5-95) and 25 (range: 1-82) years, respectively. Patients aged > 55 years and those who did not complete primary school had higher odds of being decedents (matched odds ratio [mOR] 6.3, 95% CI: 1.2-63.0, P = 0.03; mOR 8.6, 95% CI: 1.8-81.7, P < 0.01, respectively). Patients who received immediate oral rehydration solution (ORS) at the CTC had lower odds of dying than those who did not receive immediate ORS (mOR 0.1, 95% CI: 0.0-0.6, P = 0.02). Cholera prevention and outbreak response should include efforts focused on ensuring access to timely, appropriate care for older adults and less educated populations at home and in health facilities. |
Intimate partner violence before and during pregnancy, and prenatal counseling among women with a recent live birth, United States, 2009-2015
Kapaya M , Boulet SL , Warner L , Harrison L , Fowler D . J Womens Health (Larchmt) 2019 28 (11) 1476-1486 Background: Intimate partner violence (IPV) is a leading cause of injury for reproductive-aged women. Clinical guidelines exist to assist providers in counseling women for IPV, but information on provider counseling among pregnant women from population-based sources is limited. Methods: Data for 2009-2015 from 37 states and New York City participating in the Pregnancy Risk Assessment Monitoring System (PRAMS) were analyzed (n = 258,263). We compared prevalence estimates overall and by site, of physical IPV occurring before and/or during pregnancy, and prenatal counseling on physical IPV. Multivariable logistic regression was used to identify factors associated with receiving prenatal counseling on physical IPV. Results: Overall, 3.8% of women reported experiencing any physical IPV in the 12 months before and/or during pregnancy (range: 1.5% [Connecticut] to 7.2% [Mississippi]). Prevalence of prenatal IPV counseling was 51.0% (range: 30.2% [Utah] to 63.1% [New Mexico]). Receipt of prenatal counseling on depression predicted a fourfold increase in prevalence of receiving counseling on physical IPV (adjusted prevalence ratio [aPR] = 4.20, 95% confidence interval [CI]: 4.06-4.34). In addition, non-Hispanic black race versus non-Hispanic white race, and having less than a high school education were associated with higher prevalence of receipt of IPV counseling ([aPR = 1.16, 95% CI: 1.14-1.18] and [aPR = 1.11, 95% CI: 1.08-1.13], respectively). Conclusion: Almost 4% of women with a recent live birth reported physical IPV before and/or during pregnancy. Only half of women received counseling on IPV during prenatal care, with counseling rates varying widely among states. Increased adherence to guidelines for universal screening and counseling of women could ensure all women are offered appropriate support and referral. |
Prevalence and maternal characteristics associated with receipt of prenatal care provider counseling about medications safe to take during pregnancy
D'Angelo DV , Bauman BL , Broussard CS , Tong VT , Ko JY , Kapaya M , Harrison L , Ahluwalia IB . Prev Med 2019 126 105743 Use of some medications during pregnancy can be harmful to the developing fetus, and discussion of the risks and benefits with prenatal care providers can provide guidance to pregnant women. We used Pregnancy Risk Assessment Monitoring System data collected for 2015 births aggregated from 34 US states (n=40,480 women) to estimate the prevalence of self-reported receipt of prenatal care provider counseling about medications safe to take during pregnancy. We examined associations between counseling and maternal characteristics using adjusted prevalence ratios (aPR). The prevalence of counseling on medications safe to take during pregnancy was 89.2% (95% confidence interval [CI]: 88.7-89.7). Women who were nulliparous versus multiparous (aPR 1.03; 95% CI: 1.02-1.04), who used prescription medications before pregnancy versus those who did not, (aPR 1.03; 95% CI: 1.02-1.05), and who reported having asthma before pregnancy versus those who did not, (aPR 1.05; 95% CI: 1.01-1.08) were more likely to report receipt of counseling. There was no difference in counseling for women with pre-pregnancy diabetes, hypertension, and/or depression compared to those without. Women who entered prenatal care after the first trimester were less likely to report receipt of counseling (aPR 0.93; 95% CI: 0.91-0.96). Overall, self-reported receipt of counseling was high, with some differences by maternal characteristics. Although effect estimates were small, it is important to ensure that information is available to prenatal care providers about medication safety during pregnancy, and that messages are communicated to women who are or might become pregnant. |
Use of electronic vapor products before, during, and after pregnancy among women with a recent live birth - Oklahoma and Texas, 2015
Kapaya M , D'Angelo DV , Tong VT , England L , Ruffo N , Cox S , Warner L , Bombard J , Guthrie T , Lampkins A , King BA . MMWR Morb Mortal Wkly Rep 2019 68 (8) 189-194 Electronic vapor products (EVPs) comprise a diverse group of devices, including electronic cigarettes (e-cigarettes). EVP users inhale an aerosol that typically contains nicotine, flavorings, and other additives (1). Nicotine is a developmental toxicant that adversely affects pregnancy and infant outcomes (2). Data from the 2015 Pregnancy Risk Assessment Monitoring System (PRAMS) for Oklahoma and Texas were analyzed to estimate population-based EVP use among women with a recent live birth. EVP use before pregnancy (defined as >3 months before pregnancy) and around the time of pregnancy (defined as any time during the 3 months before pregnancy, the last 3 months of pregnancy, or 2-6 months after delivery), reasons for EVP use, and dual use of EVPs and cigarettes were assessed. Prevalence of EVP use was 10.4% before pregnancy and 7.0% around the time of pregnancy, including 1.4% during the last 3 months of pregnancy. Among women using EVPs during the last 3 months of pregnancy, 38.4% reported use of EVPs containing nicotine, and 26.4% were unsure of nicotine content. Among women who had used EVPs and cigarettes, dual use prevalence was 38.0% in the 3 months before pregnancy, 7.7% during the last 3 months of pregnancy, and 11.8% in the 2-6 months after delivery. The most frequently reported reasons for EVP use around the time of pregnancy were curiosity (54.0%), the perception that EVPs might help with quitting or reducing cigarette smoking (45.2%), and the perception of reduced harm to the mother, when compared with cigarette smoking (45.2%). Clear messages that EVP use is not safe during pregnancy are needed, and broad, barrier-free access to evidence-based tobacco cessation strategies need to be made available. |
Pregnancy Risk Assessment Monitoring System for dads: Public health surveillance of new fathers in the perinatal period
Garfield CF , Simon CD , Harrison L , Besera G , Kapaya M , Pazol K , Boulet S , Grigorescu V , Barfield W , Warner L . Am J Public Health 2018 108 (10) 1314-1315 As Father’s Day approaches each June, the nation pauses to reflect on the importance of fathers. In the United States, approximately 60% of American men are fathers, 82% of whom live with at least one of their children.1 Over the past few decades, we have learned that paternal involvement is strongly associated with better prenatal and postnatal maternal health and with improved developmental outcomes for children.2 A number of key indicators demonstrate the influence fathers have on perinatal maternal and child health,3 including improvements in first trimester prenatal care initiation, infant morbidity and mortality, and breastfeeding initiation and continuation. Although fathers’ involvement in families is increasing, there has been limited research on how fatherhood affects the health and well-being of fathers themselves, especially around the time of the transition into fatherhood. In particular, surveillance efforts examining new fathers’ behaviors and attitudes remain suboptimal. Expectant fathers’ preconception health is a newly emerging area of research focused on measuring the health of men during their reproductive years, a key tenet of men’s health.4 |
Cholera epidemic - Lusaka, Zambia, October 2017-May 2018

MMWR Morb Mortal Wkly Rep 2018 67 (19) 556-559 On October 6, 2017, an outbreak of cholera was declared in Zambia after laboratory confirmation of Vibrio cholerae O1, biotype El Tor, serotype Ogawa, from stool specimens from two patients with acute watery diarrhea. The two patients had gone to a clinic in Lusaka, the capital city, on October 4. Cholera cases increased rapidly, from several hundred cases in early December 2017 to approximately 2,000 by early January 2018 (Figure). In collaboration with partners, the Zambia Ministry of Health (MoH) launched a multifaceted public health response that included increased chlorination of the Lusaka municipal water supply, provision of emergency water supplies, water quality monitoring and testing, enhanced surveillance, epidemiologic investigations, a cholera vaccination campaign, aggressive case management and health care worker training, and laboratory testing of clinical samples. In late December 2017, a number of water-related preventive actions were initiated, including increasing chlorine levels throughout the city's water distribution system and placing emergency tanks of chlorinated water in the most affected neighborhoods; cholera cases declined sharply in January 2018. During January 10-February 14, 2018, approximately 2 million doses of oral cholera vaccine were administered to Lusaka residents aged >/=1 year. However, in mid-March, heavy flooding and widespread water shortages occurred, leading to a resurgence of cholera. As of May 12, 2018, the outbreak had affected seven of the 10 provinces in Zambia, with 5,905 suspected cases and a case fatality rate (CFR) of 1.9%. Among the suspected cases, 5,414 (91.7%), including 98 deaths (CFR = 1.8%), occurred in Lusaka residents. |
A foodborne disease outbreak investigation experience in a college in Lusaka, Zambia, 2017
Kapaya F , Mwansa FD , Sakubita P , Gama A , Langa N , Chewe O , Mutale L , Nanzaluka F , Gershom C , Chola M , Kapata N , Sinyange N , Chibuye S , Yard E . Pan Afr Med J 2018 29 Introduction: On 19 March 2017, an outbreak of unknown etiology was reported among students at a college in Lusaka, Zambia. We investigated to confirm the outbreak, identify exposures, determine the aetiological agent, and implement preventive measures. Methods: We conducted an unmatched case-control study. Cases and controls were selected conveniently. A suspected case was diarrhea or abdominal pains in any student at College A and Controls were asymptomatic students at College A during 18-23 March. We interviewed cases and controls about exposures to suspected food and water and collected saved food samples and swabs from food-handlers' hands and kitchen surfaces for culture. We analyzed data using Epi-info v 7.2 (Atlanta, Georgia). Results: We identified 59 suspected case-patients. Predominant symptoms were diarrhea (n = 51.83%) and abdominal pains (n = 44.75%). The outbreak started on 18 March, peaked on 19, and concluded on 20 March. We interviewed 30 case-patients and 71 controls. Exposures associated with increased odds of illness included eating food served at dinner on Saturday (18 March) in school cafeteria (OR = 5.8, 95% CI = 2.0-16.7); specifically, eating beans at Saturday dinner (OR = 21.6, 95% CI = 4.5-104) and drinking water supplied at school (OR = 8.8, 95% CI = 1.45-53.6). Samples from all food-handlers (n = 13) yielded Staphylococcus aureus and all food samples (n = 3) yielded Escherichia coli, Staphylococcus aureus and fecal coliforms. Conclusion: The results suggest a foodborne outbreak caused by consumption of contaminated food served at dinner on 18 March at College A. We educated the food handlers and school management about the importance of disinfection of preparation surfaces, supervision of food handling and handwashing practices. |
Trends in repeat births and use of postpartum contraception among teens - United States, 2004-2015
Dee DL , Pazol K , Cox S , Smith RA , Bower K , Kapaya M , Fasula A , Harrison A , Kroelinger CD , D'Angelo D , Harrison L , Koumans EH , Mayes N , Barfield WD , Warner L . MMWR Morb Mortal Wkly Rep 2017 66 (16) 422-426 Teen* childbearing (one or more live births before age 20 years) can have negative health, social, and economic consequences for mothers and their children (1). Repeat teen births (two or more live births before age 20 years) can constrain the mother's ability to take advantage of educational and workforce opportunities (2), and are more likely to be preterm or of low birthweight than first teen births (3). Despite the historic decline in the U.S. teen birth rate during 1991-2015, from 61.8 to 22.3 births per 1,000 females aged 15-19 years (4), many teens continue to have repeat births (3). The American College of Obstetricians and Gynecologists and the American Academy of Pediatrics both recommend that clinicians counsel women (including teens) during prenatal care about birth spacing and postpartum contraceptive use (5), including the safety and effectiveness of long-acting reversible methods that can be initiated immediately postpartum. To expand upon prior research assessing patterns and trends in repeat childbearing and postpartum contraceptive use among teens with a recent live birth (i.e., 2-6 months after delivery) (3), CDC analyzed data from the National Vital Statistics System natality files (2004 and 2015) and the Pregnancy Risk Assessment Monitoring System (PRAMS; 2004-2013). The number and proportion of teen births that were repeat births decreased from 2004 (82,997; 20.1%) to 2015 (38,324; 16.7%); in 2015, the percentage of teen births that were repeat births varied by state from 10.6% to 21.4%. Among sexually active teens with a recent live birth, postpartum use of the most effective contraceptive methods (intrauterine devices and contraceptive implants) increased from 5.3% in 2004 to 25.3% in 2013; however, in 2013, approximately one in three reported using either a least effective method (15.7%) or no method (17.2%). Strategies that comprehensively address the social and health care needs of teen parents can facilitate access to and use of effective methods of contraception and help prevent repeat teen births. |
Nicotine replacement therapy and other interventions for pregnant smokers: Pregnancy Risk Assessment Monitoring System, 2009-2010
Kapaya M , Tong V , Ding H . Prev Med 2015 78 92-100 BACKGROUND: Current U.S. guidelines recommend consideration of nicotine replacement therapy (NRT) for pregnant smokers if behavioral therapies fail, only under close supervision of a provider, and after discussion of known risks of continued smoking and possible risks of NRT. The percentage of pregnant smokers offered NRT by their prenatal care providers is unknown. PURPOSE: The study aims to calculate the percentage of pregnant smokers offered cessation intervention and NRT and assess independent associations between selected maternal characteristics and being offered NRT. METHODS: Data were analyzed from the 2009-2010 Pregnancy Risk Assessment Monitoring System from four states that asked about provider practices for prenatal smoking cessation. Adjusted prevalence ratios were calculated to examine associations between being offered NRT, selected maternal characteristics, and smoking level. Variables used in adjusted models were based on factors associated with smoking cessation during pregnancy from prior literature and included race, age, education, insurance type, and stress. RESULTS: Of 3559 women who smoked 3 months before pregnancy, 77.4% (95% CI: 74.2, 80.3) of 3rd trimester smokers and 42% (95% CI: 38.5, 46.4) of women who quit smoking during pregnancy were offered at least one cessation method. Among smokers, 19.1% (95% CI: 16.5, 22.1) were offered NRT and of these, almost all (94%) were offered another cessation method. CONCLUSIONS: One in five pregnant smokers was offered NRT. About a quarter of pregnant smokers did not receive any interventions to stop smoking. There may still be reluctance to provide NRT to pregnant women, despite known harms of continued smoking during pregnancy. |
Pregnancy Risk Assessment Monitoring System and the W.K. Kellogg Foundation joint project to enhance maternal and child health surveillance: focus on collaboration
Ahluwalia IB , Harrison L , Simpson P , Wako E , Helms Shealy K , Kapaya M , Williams T , Williams L , D'Angelo D . J Womens Health (Larchmt) 2015 24 (4) 257-60 Maternal and child health (MCH) surveillance data are important for understanding gaps in services and disparities in burden of disease, access to care, risk behaviors, and health outcomes. However, national and state surveillance systems are not always designed to gather sufficient data for calculating reliable estimates of the health conditions among high-risk or underrepresented population subgroups living in smaller geographic areas. The Centers for Disease Control and Prevention's Pregnancy Risk Assessment Monitoring System (PRAMS) has conducted surveillance for over 25 years in collaboration with state and city health departments. In 2012, PRAMS embarked on a multiyear collaboration with the W.K. Kellogg Foundation (WKKF) to include oversampling of minority and low-income women in selected geographic areas in four states (Louisiana, Michigan, Mississippi, and New Mexico) where the WKKF funded extensive place-based initiatives are located. The PRAMS-WKKF collaboration has broad implications for promoting meaningful collaboration between public, private, local, state, and federal organizations to address MCH data gaps on disparities, and for improving the availability of information needed for MCH programs, policy makers, and women. |
