Jie Chen and colleagues will publish a study examining the behavioral health treatment among individuals with co-occurring opioid use disorder and mental illness

Although chronic life strain is often found to be associated with adverse health outcomes, empirical research is lacking on the health implications of persistent role overload that many women around the world are subject to, the so-called double burden of work and family responsibilities. Using data from the Cebu Longitudinal Health and Nutrition Survey (1994-2012), we examined the linkage between time-use profiles and body mass index (BMI) trajectories for Filipino women over an 18-year span. Out of the four classes of women with differential levels of a combination of work and family duties, the group with the heaviest double burden has the highest average BMI. In addition, those who have remained in this class for three or more waves of data not only have higher BMI on average but also have experienced the steepest rate of increase in BMI upon transition from midlife to old age.

Purpose Psychosocial stress has been associated with susceptibility to many infectious pathogens. We evaluated the association between perceived stress and incident sexually transmitted infections (STIs;  Chlamydia trachomatis ,  Neisseria gonorrhoeae , and  Trichomonas vaginalis  genital infections) in a prospective study of women. Stress may increase vulnerability to STIs by suppressing immune function and altering the protective vaginal microbiota. Methods Using the 1999 Longitudinal Study of Vaginal Flora (n  = 2439), a primarily African American cohort of women, we fitted Cox proportional hazards models to examine the association between perceived stress and incident STIs. We tested  bacterial vaginosis  (measured by Nugent Score) and sexual behaviors (condom use, number of partners, and partner concurrence) as mediators using VanderWeele's difference method. Results Baseline perceived stress was associated with incident STIs both before and after adjusting for confounders (adjusted hazard ratio = 1.015; 95% confidence interval, 1.005–1.026). Nugent score and sexual behaviors significantly mediated 21% and 65% of this adjusted association, respectively, and 78% when included together in the adjusted model. Conclusions This study advances understanding of the relationship between perceived stress and STIs and identifies high-risk sexual behaviors and development of bacterial vaginosis—both known risk factors for STIs—as mechanisms underlying this association.

Deferred Action for Childhood Arrivals (DACA) recipients face an uncertain fate as their future in the United States is being debated. Yet even before the program was introduced in June 2012 and became endangered in September 2017, they encountered challenges in navigating a fragmented health care landscape throughout the United States. This paper focuses on  DACA  recipients' experiences in accessing health care throughout their lives, both before and after receiving DACA. We conducted semi-structured interviews and questionnaires with 30 DACA recipients living in Maryland between April–December 2016. Participants represented 13 countries of origin and ranged in age between 18 and 28. Results demonstrate that DACA recipients have had punctuated coverage throughout their lives and continue to face constrained access despite temporary gains in status. Health care access is further stratified within their mixed-status families. Participants have also experienced shifts in their health care coverage due to moving between jurisdictions with variable eligibility and changing life circumstances related to family, school, and employment. This article underscores the importance of examining young adult immigrants' access to care over time as they weather changes in the broader policy context and in highly variable contexts of reception nationwide, shaped by state, but also county and city policies and programs. The challenges and gaps in coverage DACA recipients face also underscore the need for both health care and immigration reform.

  BACKGROUND: Stroke is a leading cause of morbidity and mortality in the United States. Associations between short-term exposures to particulate matter (PM) air pollution and stroke are inconsistent. Many prior studies have used administrative and hospitalization databases where misclassification of the type and timing of the stroke event may be problematic. METHODS: In this case-crossover study, we used a nationwide kriging model to examine short-term ambient exposure to PM10 and PM2.5 and risk of ischemic and hemorrhagic stroke among men enrolled in the Health Professionals Follow-up Study. Conditional logistic regression models were used to obtain estimates of odds ratios (OR) and 95% confidence intervals (CI) associated with an interquartile range (IQR) increase in PM2.5 or PM10. Lag periods up to 3 days prior to the stroke event were considered in addition to a 4-day average. Stratified models were used to examine effect modification by patient characteristics. RESULTS: Of the 727 strokes that occurred between 1999 and 2010, 539 were ischemic and 122 were hemorrhagic. We observed positive statistically significant associations between PM10 and ischemic stroke (ORlag0-3 = 1.26; 95% CI: 1.03-1.55 per IQR increase [14.46 μg/m3]), and associations were elevated for nonsmokers, aspirin nonusers, and those without a history of high cholesterol. However, we observed no evidence of a positive association between short-term exposure to PM and hemorrhagic stroke or between PM2.5 and ischemic stroke in this cohort. CONCLUSIONS: Our study provides evidence that ambient PM10 may be associated with higher risk of ischemic stroke and highlights that ischemic and hemorrhagic strokes are heterogeneous outcomes that should be treated as such in analyses related to air pollution.

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.
