Receipt of reproductive health services among sexually experienced persons aged 15-19 years - National Survey of Family Growth, United States, 2006-2010
Tyler CP , Warner L , Gavin L , Barfield W . MMWR Suppl 2014 63 (2) 89-98 The prevention of pregnancy, childbirth, and sexually transmitted diseases (STDs) among teenagers has garnered recent attention both from public health and clinical organizations. In 2011, the U.S. birth rate among teenagers reached a historic low of 31.3 births per 1,000 females aged 15-19 years and has decreased 49% percent from 1991 to 2011. Despite recent decreases, U.S. birth rates among teenagers remain higher than those in other industrialized countries. For example, in 2009, the U.S. teenage birth rate was approximately 1.5 times the birth rate in the United Kingdom, nearly 3 times the birth rate in Canada, and nearly 8 times the birth rate of Denmark. Approximately 20% of births to teenagers aged 15-19 years are repeat births, and significant disparities by race and ethnicity persist. |
Dual use of condoms with other contraceptive methods among adolescents and young women in the United States
Tyler CP , Whiteman MK , Kraft JM , Zapata LB , Hillis SD , Curtis KM , Anderson J , Pazol K , Marchbanks PA . J Adolesc Health 2014 54 (2) 169-75 PURPOSE: To estimate the prevalence of and factors associated with dual method use (i.e., condom with hormonal contraception or an intrauterine device) among adolescents and young women in the United States. METHODS: We used 2006-2010 National Survey of Family Growth data from 2,093 unmarried females aged 15-24 years and at risk for unintended pregnancy. Using multivariable logistic regression, we estimated adjusted odds ratios (aORs) and 95% confidence intervals (CIs) to assess the associations between dual method use at last sex and sociodemographic, behavioral, reproductive history, and sexual behavior factors. RESULTS: At last sex, 20.7% of adolescents and young women used dual methods, 34.4% used condoms alone, 29.1% used hormonal contraception or an intrauterine device alone, and 15.8% used another method or no method. Factors associated with decreased odds of dual method use versus dual method nonuse included having a previous pregnancy (aOR = .44, 95% CI .27-.69), not having health insurance coverage over the past 12 months (aOR = .41, 95% CI .19-.91), and having sex prior to age 16 (aOR = .49, 95% CI .30-.78). CONCLUSIONS: The prevalence of dual method use is low among adolescents and young women. Adolescents and young women who may have a higher risk of pregnancy and sexually transmitted infections (e.g., those with a previous pregnancy) were less likely to use dual methods at last sex. Interventions are needed to increase the correct and consistent use of dual methods among adolescents and young women who may be at greater risk for unintended pregnancy and sexually transmitted infections. |
When can a woman have an intrauterine device inserted? A systematic review
Whiteman MK , Tyler CP , Folger SG , Gaffield ME , Curtis KM . Contraception 2012 87 (5) 666-73 BACKGROUND: Intrauterine device (IUD) insertion during menses may be viewed as preferable by some providers, as it provides reassurance that the woman is not pregnant. However, this practice may result in unnecessary inconvenience and cost to women. The objective of this systematic review is to evaluate the evidence for the effect of inserting IUDs on different days of the menstrual cycle on contraceptive continuation, effectiveness and safety. STUDY DESIGN: We searched the MEDLINE database for peer-reviewed articles published in any language from database inception through March 2012 concerning the effect of inserting copper IUDs (Cu-IUD) or levonorgestrel-releasing IUDs (LNG-IUDs) on different days of the menstrual cycle on contraceptive continuation, effectiveness, and safety. The quality of each individual piece of evidence was assessed using the United States Preventive Services Task Force grading system. RESULTS: We identified eight articles that met the criteria for review. Each study examined the Cu-IUD; no studies were identified that examined the LNG-IUD. Overall, these studies suggest that timing of Cu-IUD insertion has little effect on longer term outcomes (rates of continuation, removal, expulsion, or pregnancy) or on shorter term outcomes (pain at insertion, bleeding at insertion, immediate expulsion). Specifically, there was no evidence to suggest that outcomes were better when Cu-IUD insertions were performed during menses. Limitations of the studies include small sample sizes for insertions performed during later days of the menstrual cycle and non-randomized assignment to timing of insertion. CONCLUSIONS: There is fair evidence (body of evidence grading: II-2, fair) indicating that timing of Cu-IUD insertion has little effect on contraceptive continuation, effectiveness or safety. |
Impact of fetal death reporting requirements on early neonatal and fetal mortality rates and racial disparities
Tyler CP , Grady SC , Grigorescu V , Luke B , Todem D , Paneth N . Public Health Rep 2012 127 (5) 507-15 OBJECTIVE: Racial disparities in infant and neonatal mortality vary substantially across the U.S. with some states experiencing wider disparities than others. Many factors are thought to contribute to these disparities, but state differences in fetal death reporting have received little attention. We examined whether such reporting requirements may explain national variation in neonatal and fetal mortality rates and racial disparities. METHODS: We used data on non-Hispanic white and non-Hispanic black infants from the U.S. 2000-2002 linked birth/infant death and fetal death records to determine the degree to which state fetal death reporting requirements explain national variation in neonatal and fetal mortality rates and racial disparities. States were grouped depending upon whether they based the lower limit for fetal death reporting on birthweight alone, gestational age alone, both birthweight and gestational age, or required reporting of all fetal deaths. Traditional methods and the fetuses-at-risk approach were used to calculate mortality rates, 95% confidence intervals, and relative and absolute racial disparity measures in these four groups. RESULTS: States with birthweight-alone fetal death thresholds substantially underreported fetal deaths at lower gestations and slightly overreported neonatal deaths at older gestations. This finding was reflected by these states having the highest neonatal mortality rates and disparities, but the lowest fetal mortality rates and disparities. CONCLUSIONS: Using birthweight alone as a reporting threshold may promote some shift of fetal deaths to newborn deaths, contributing to racial disparities in neonatal mortality. The adoption of a uniform national threshold for reporting fetal deaths could reduce systematic differences in live birth and fetal death reporting. |
The effect of body mass index and weight change on epithelial ovarian cancer survival in younger women: a long-term follow-up study
Tyler CP , Whiteman MK , Zapata LB , Hillis SD , Curtis KM , McDonald J , Wingo PA , Kulkarni A , Marchbanks PA . J Womens Health (Larchmt) 2012 21 (8) 865-71 OBJECTIVE: The objective of this study was to assess the relationship between body mass index (BMI) and epithelial ovarian cancer survival among young women. METHODS: We conducted a cohort analysis of 425 women aged 20-54 years with incident epithelial ovarian cancer enrolled during 1980-1982 in Cancer and Steroid Hormone (CASH), a population-based, case-control study. Participants' vital status was ascertained though linkage with the Surveillance, Epidemiology and End Results (SEER) program. Using Cox proportional hazards models, we estimated adjusted hazard ratios (HR) and 95% confidence intervals (CI) for the association between survival and usual adult BMI, BMI at age 18, and weight change from age 18 to adult. RESULTS: During a follow-up of up to 17 years, 215 women died. Compared to women with an adult BMI in the lowest quartile (<20.7), women in the second (20.8-22.5), third (22.6-24.9), and fourth (≥25.0) quartiles were not at increased risk for death (HR 1.2, 95% CI 0.8-1.8; HR 1.1, 95% CI 0.7-1.6; and HR 0.9, 95% CI 0.6-1.4, respectively) (p trend=0.6). Similarly, neither age 18 BMI nor weight change were associated with ovarian cancer survival. CONCLUSIONS: Although elevated BMI is associated with increased ovarian cancer risk among young women, we found no evidence of its association with ovarian cancer survival in this population. |
Health care provider attitudes and practices related to intrauterine devices for nulliparous women
Tyler CP , Whiteman MK , Zapata LB , Curtis KM , Hillis SD , Marchbanks PA . Obstet Gynecol 2012 119 (4) 762-71 OBJECTIVE: To examine predictors of health care providers perceiving intrauterine devices (IUDs) as unsafe for nulliparous women and of infrequent provision of IUDs to nulliparous women. METHODS: We analyzed questionnaire data obtained during December 2009 to March 2010 from 635 office-based providers (physicians) and 1,323 Title X clinic providers (physicians, physician assistants, certified nurse midwives, nurse practitioners, and nurses). Using multivariable logistic regression, we estimated adjusted odds ratios (ORs) and 95% confidence intervals (CIs) of the associations between patient, health care provider, and clinic and practice variables and provider misconceptions about the safety of IUDs for nulliparous women and with infrequent IUD provision. RESULTS: Approximately 30% of respondents had misconceptions about the safety of IUDs for nulliparous women. Factors associated with increased odds of misconceptions about the copper IUD and levonorgestrel-releasing IUD included: being an office-based family medicine physician (copper IUD adjusted OR 3.20, 95% CI 1.73-5.89; levonorgestrel-releasing IUD adjusted OR 2.03, 95% CI 1.10-3.76); not being trained in IUD insertion (copper IUD adjusted OR 4.72, 95% CI 2.32-9.61; levonorgestrel-releasing IUD adjusted OR 2.64, 95% CI 1.34-5.22); and nonavailability of IUDs on-site at their practice or clinic (copper IUD adjusted OR 2.18, 95% CI 1.20-3.95; levonorgestrel-releasing IUD adjusted OR 3.45, 95% CI 1.95-6.08). More than 60% of providers infrequently provided IUDs to nulliparous women. Nonavailability of IUDs on-site (copper IUD adjusted OR 1.78, 95% CI 1.01-3.14; levonorgestrel-releasing IUD adjusted OR 2.10, 95% CI 1.22-3.62) and provider misconceptions about safety (copper IUD adjusted OR 6.04, 95% CI 2.00-18.31; levonorgestrel-releasing IUD adjusted OR 6.91, 95% CI 3.01-15.85) were associated with infrequent IUD provision. CONCLUSION: Health care provider misconceptions about the safety of IUDs for nulliparous women are prevalent and are associated with infrequent provision. Improved health care provider education and IUD availability are needed to increase IUD use among nulliparous women. LEVEL OF EVIDENCE: III. |
