Article Reference Troff document (with manpage macros)The association between interpregnancy interval and severe maternal morbidities using revised national birth certificate data: A probabilistic bias analysis
Severe maternal morbidity continues to be on the rise in the US. Short birth spacing is a modifiable risk factor associated with maternal morbidity, yet few studies have examined this association, possibly due to few available data sources to examine these rare events. To examine the association between interpregnancy interval (IPI) and severe maternal morbidity using near‐national birth certificate data and account for known under‐reporting using probabilistic bias analysis. We used revised 2014‐2017 birth certificate data, restricting to resident women with a non–first‐born singleton birth. We examined the following: (a) maternal blood transfusion, (b) admission to intensive care unit (ICU), (c) uterine rupture (among women with a prior caesarean delivery) and (d) third‐ or fourth‐degree perineal laceration (among vaginal deliveries) by IPI categories (<6, 6‐11, 12‐17, 18‐23, 24‐59 and 60+ months). Risk ratios and 95% confidence intervals were estimated using log‐binomial regression, adjusting for select maternal characteristics. Probabilistic bias analyses were performed. Compared with IPI 18 to 23 months, adjusted models revealed that the risk of maternal transfusion followed a U‐shaped curve with IPI, while risk of ICU admission and perineal laceration increased with longer IPI. Risk of uterine rupture was highest among IPI <6 months. With the exception of maternal transfusion, these findings persisted regardless of the extent or type of misclassification examined in bias analyses. Associations between IPI and maternal morbidity varied by outcome, even after adjusting for misclassification of SMM. Differences across maternal health outcomes should be considered when counselling and making recommendations regarding optimal birth spacing.

Article Reference Troff document (with manpage macros)Risk and protective factors associated with BV chronicity among women in Rakai, Uganda
Objectives To assess risk and protective factors associated with bacterial vaginosis (BV) chronicity ascertained by Nugent score criteria. Methods A longitudinal cohort study included 255 sexually experienced, postmenarcheal women who provided weekly self-collected vaginal swabs for up to 2 years. Vaginal swabs were scored using Nugent criteria and classified as normal (≤3), intermediate (4–6) and Nugent-BV (≥7). Detailed behavioural/health information were assessed every 6 months. A per-woman longitudinal summary measure of BV chronicity was defined as the percentage of each woman’s weekly vaginal assessments scored as Nugent-BV over a 6-month interval. Risk and protective factors associated with BV chronicity were assessed using multiple linear regression with generalised estimating equations. Results Average BV chronicity was 39% across all follow-up periods. After adjustment, factors associated with BV chronicity included baseline Nugent-BV (β=35.3, 95% CI 28.6 to 42.0) compared with normal baseline Nugent scores and use of unprotected water for bathing (ie, rainwater, pond, lake/stream) (β=12.0, 95% CI 3.4 to 20.5) compared with protected water sources (ie, well, tap, borehole). Women had fewer BV occurrences if they were currently pregnant (β=−6.6, 95% CI −12.1 to 1.1), reported consistent condom use (β=−7.7, 95% CI −14.2 to 1.3) or their partner was circumcised (β=−5.8, 95% CI −11.3 to 0.3). Conclusions Factors associated with higher and lower values of BV chronicity were multifactorial. Notably, higher values of BV chronicity were associated with potentially contaminated bathing water. Future studies should examine the role of waterborne microbial agents in the pathogenesis of BV.

Article Reference Troff document (with manpage macros)Availability of Services Related to Achieving Pregnancy in U.S. Publicly Funded Family Planning Clinics
Background Recognizing that quality family planning services should include services to help clients who want to become pregnant, the objective of our analysis was to examine the distribution of services related to achieving pregnancy at publicly funded family planning clinics in the United States. Methods A nationally representative sample of publicly funded clinics was surveyed in 2013–2014 (n = 1615). Clinic administrators were asked about several clinical services and screenings related to achieving pregnancy: basic infertility services, reproductive life plan assessment, screening for body mass index, screening for sexually transmitted diseases, provision of natural family planning services, infertility treatment, and primary care services. The percentage of clinics offering each of these services was compared by Title X funding status; prevalence ratios (PR) and 95% confidence intervals (CIs) were estimated after adjusting for clinic characteristics. Results Compared to non-Title X clinics, Title X clinics were more likely to offer reproductive life plan assessment (adjusted PR [aPR], 1.62; 95% CI, 1.42–1.84), body mass index screening for men (aPR, 1.10; 95% CI, 1.01–1.21), screening for sexually transmitted diseases (aPRs ranged from 1.21 to 1.37), and preconception health care for men (aPR, 1.10; 95% CI, 1.01–1.20). Title X clinics were less likely to offer infertility treatment (aPR, 0.55; 95% CI, 0.40–0.74) and primary care services (aPR, 0.74; 95% CI, 0.68–0.80) and were just as likely to offer basic infertility services, preconception health care services for women, natural family planning, and body mass index screening in women. Conclusions The availability of selected services related to achieving pregnancy differed by Title X status. A follow-up assessment after publication of national family planning recommendations is underway.

Article Reference Troff document (with manpage macros)Intimate Partner Violence and Effectiveness Level of Contraceptive Selection Post-Abortion
Materials and Methods:  Using data on 245 women who were attending an urban hospital abortion clinic, we assessed whether women had ever experienced emotional, physical, or sexual IPV. Effectiveness of women's post-abortion contraceptive method selection was categorized into high (intrauterine device [IUD] and implant), moderate (pill, patch, ring, and shot), and low (condoms, emergency contraception, and none) effectiveness. Using multinomial logistic regression, we examined the relationship between number of types of IPV experienced and post-abortion contraceptive method effectiveness, adjusting for sociodemographics, prior abortion, having children, abortion trimester, importance of avoiding pregnancy in the next year, pre-abortion psychological distress, and effectiveness level of the contraceptive method women were planning to use before contraceptive counseling. Results:  Twenty-seven percent (27%) of women experienced two or three types of IPV, 35% experienced one IPV type, and 38% experienced no IPV. Compared to women with no histories of IPV, women who experienced two or more types of IPV during their lifetimes were more likely to choose contraceptive methods with moderate effectiveness (adjusted odds ratio [AOR] = 5.23, 95% confidence interval [CI]: 1.13–24.23, p = 0.035) and high effectiveness (AOR = 5.01, 95% CI: 1.12–22.39, p = 0.035) than those with low effectiveness. Conclusion:  Women who experienced two or more types of lifetime IPV selected more effective contraceptive methods post-abortion. Access to contraceptives that are not partner dependent, including long-acting reversible contraceptives (LARC), may be particularly important for women who have experienced multiple types of IPV.

Article Reference Troff document (with manpage macros)Cohort Increases In Sex With Same-Sex Partners: Do Trends Vary by Gender, Race, and Class?
We examine change across U.S. cohorts born between 1920 and 2000 in their probability of having had sex with same-sex partners in the last year and since age 18. Using data from the 1988–2018 General Social Surveys, we explore how trends differ by gender, race, and class background. We find steep increases across birth cohorts in the proportion of women who have had sex with both men and women since age 18, whereas increases for men are less steep. We suggest that the trends reflect an increasingly accepting social climate, and that women’s steeper trend is rooted in a long-term asymmetry in gender change, in which nonconformity to gender norms is more acceptable for women than men. We also find evidence that, among men, the increase in having had sex with both men and women was steeper for black than for white men, and for men of lower socioeconomic status; we speculate that the rise of mass incarceration among less privileged men may have influenced this trend.

Article Reference Troff document (with manpage macros)Sexual Minority Health Disparities: An Examination of Age-Related Trends Across Adulthood In a National Cross-Sectional Sample
Purpose:  Sexual minorities experience signi fi cant health disparities across a variety of mental, behav ioral, and physical health indicators. Yet, an understanding of the etiology and progression of sexual minority health disparities across the lifespan is limited. Methods:  We used the U.S. National Epidemiologic Survey of Alcohol and Related Conditions III to  evaluate the association between sexual minority status and seven past-year health outcomes (alcohol  use disorder, tobacco use disorder, drug use disorder, major depressive episode, generalized anxiety  disorder, sexually transmitted infection, and cardiovascular conditions). To do this, we used unadjusted  and adjusted logistic regression among our study sample (n ¼ 30,999; aged 18 e 65 years) and time- varying effect models to evaluate how sexual orientation differences in these outcomes vary across  adulthood. Results:  Relative to heterosexuals, sexual minorities had elevated odds of past-year alcohol use disorder  and drug use disorder across all ages (18 e 65 years) although the magnitude of the disparity varies by  age. Sexual minorities were also more likely to experience major depressive episode, generalized anxiety  disorder, tobacco use disorder, sexually transmitted infection, and cardiovascular disease, but only at  speci fi c ages. Conclusions:  Sexual minority health disparities vary appreciably across the adult lifespan, thus eluci dating critical periods for focused prevention efforts.

Article Reference Troff document (with manpage macros)Are sexual minority youth overrepresented in foster care, child welfare, and out-of-home placement? Findings from nationally representative data
BACKGROUND: Preliminary evidence suggests that sexual minority (e.g. lesbian, gay, bisexual, and same-sex attracted) youth are overrepresented in child welfare services. Yet, no study to date has been able to test this hypothesis with national data. OBJECTIVE: Using a two-study design, we test whether sexual minority youth are overrepresented in child welfare, foster care, and out-of-home placement using nationally representative data from the United States. PARTICIPANTS AND SETTING: Study 1 data are from the National Longitudinal Study of Adolescent to Adult Health (n = 14,154; Mean age = 15.4). Study 2 data are from wave three of the National Survey of Child and Adolescent Well-Being II (n = 1309; Mean age = 15.0). METHODS: For Study 1, we use adjusted logistic regression models to test differences in lifetime foster care involvement between sexual minority and heterosexual youth. In Study 2, we calculate a Disproportionality Representation Index (DRI) - a ratio of sample prevalence relative to the general population - to estimate whether sexual minority youth were overrepresented in child welfare and out-of-home care. RESULTS: Study 1 results indicate that sexual minority youth are nearly 2.5 times as likely as heterosexual youth to experience foster care placement (aOR = 2.43, 95% CI 1.40, 4.21, p = .002). Results from Study 2 show that sexual minority youth were largely overrepresented in child welfare services (DRI = 1.95-2.48) and out-of-home placement (DRI = 3.69-4.68). CONCLUSIONS: Findings are the first to demonstrate sexual minority youth's overrepresentation in child welfare, foster care, and out-of-home placement using nationally representative data and emphasizes the need for focused research on sexual minority youth involved in the child welfare system.

Article Reference Troff document (with manpage macros)Gay‐Straight Alliances, Inclusive Policy, and School Climate: LGBTQ Youths’ Experiences of Social Support and Bullying
Gay‐Straight Alliances (GSA) and school policies focused on support for lesbian, gay, bisexual, transgender, and queer/questioning youth may reduce bias‐based bullying and enhance social supports in schools. Using multivariate regression, we tested the relationship between youth reports of the presence of GSAs and LGBTQ‐focused policies, independently and mutually, with experiences bullying and perceived support ( n  =   1,061). Youth reported higher classmate support in the presence of GSAs and higher teacher support in the presence of LGBTQ‐focused policies; the presence of both GSAs and LGBTQ‐focused policies was associated with less bullying and higher perceived classmate and teacher support. The findings indicate that GSAs and LGBTQ‐focused policies are distinctly and mutually important for fostering safer and more supportive school climates for youth.

Article ReferenceLatent Classes of Polysubstance Use Among Adolescents in the United States: Intersections of Sexual Identity with Sex, Age, and Race/Ethnicity
PURPOSE: We aimed to estimate latent classes of concurrent polysubstance use and test for sexual orientation differences in latent class memberships with representative data from adolescents living in 19 U.S. states. We also tested whether sex, race/ethnicity, and age moderated the sexual identity differences in polysubstance use class memberships. METHODS: We analyzed data from 119,437 adolescents from 19 states who participated in the 2015 Youth Risk Behavior Survey. Latent class analysis characterized polysubstance use patterns based on self-reported frequency of lifetime and past-month use of alcohol (including heavy episodic drinking), tobacco (cigarettes, cigars, and smokeless tobacco), and marijuana. Multinomial logistic regression models tested differences in latent class memberships by sexual identity. Interaction terms tested whether sex, race/ethnicity, and age moderated the sexual identity differences in polysubstance use class memberships. RESULTS: A six-class model of polysubstance use fit the data best and included nonusers (61.5%), experimental users (12.2%), marijuana-alcohol users (14.8%), tobacco-alcohol users (3.8%), medium-frequency three-substance users (3.6%), and high-frequency three-substance users (4.1%). Gay/lesbian- and bisexual-identified adolescents had significantly higher odds than heterosexual-identified adolescents of being in all of the user classes compared with the nonuser class. These sexual identity differences in latent polysubstance use class memberships were generally larger for females than for males, varied occasionally by race/ethnicity, and were sometimes larger for younger ages. CONCLUSION: Compared with their heterosexual peers, gay/lesbian and bisexual adolescents-especially females-are at heightened risk of engaging in multiple types of polysubstance use. Designing, implementing, and evaluating interventions will likely reduce these sexual orientation disparities.

Article Reference Troff document (with manpage macros)The Impact of Community Size, Community Climate, and Victimization on the Physical and Mental Health of SGM Youth
Sexual and gender minority (SGM) youth experience high rates of victimization leading to health disparities. Community size and community climate are associated with health outcomes among SGM youth; however, we lack studies that include them as covariates alongside victimization to understand their collective impact on health. This study utilized minority stress theory to understand how community context shapes experiences of victimization and health among SGM youth. SGM youth in one Midwestern U.S. state completed an online survey ( n = 201) with measures of physical health, mental health, community context, and victimization. Data were analyzed via multiple regression using a path analysis framework. Results indicate that perceived climate was associated with mental, but not physical, health; Community size was unrelated to health outcomes. Victimization mediated the association between community climate and mental health. Findings are discussed in light of current literature and implications for research and practice are shared.
