Objective: This study aimed to examine the explanatory role of health behaviors, socioeconomic position (SEP), and psychosocial stressors on racial/ethnic obesity disparities in a multiethnic and multiracial sample of adults. Methods: Using data from the Chicago Community Adult Health Study (2001-2003), Oaxaca-Blinder decomposition analysis was conducted to quantify the extent to which health behaviors (fruit and vegetable consumption and physical activity), SEP, and cumulative stressors (e.g., perceived discrimination, financial strain) each explained differences in obesity prevalence in Black, US-born Hispanic, and non-US-born Hispanic compared with non-Hispanic White participants. Results: SEP and health behaviors did not explain obesity differences between racial/ethnic minorities and White individuals. Having high levels of stress in four or more domains explained 4.46% of the differences between Black and White individuals, whereas having high levels of stress in three domains significantly explained 14.13% of differences between US-born Hispanic and White. Together, the predictors explained less than 20% of differences between any racial/ethnic minority group and White individuals. Conclusions: Exposure to stressors may play a role in obesity disparities, particularly among Black and US-born Hispanic individuals. Other obesity-related risk factors need to be examined to understand the underlying mechanisms explaining obesity disparities.

Purpose This study aimed to examine whether the timing of depression onset relative to age at sexual debut is associated with teenage pregnancy. Methods Using data from 1,025 adolescent girls who reported having had sex in the National Comorbidity Survey—Adolescent Supplement, we applied cox proportional hazards models to test whether depression onset before first sex, at the same age as first sex, or after first sex compared with no depression onset was associated with experiencing a first teenage pregnancy. We examined the unadjusted risk by depression status as well as risk adjusted for adolescents' race/ethnicity, marital status, poverty level, whether the adolescent lived in a metropolitan area, living status, age at first sex, parental education, and age of mother when the adolescent was born. Results In both unadjusted and adjusted models, we found that adolescents with depression onset at the same age as having initiated sex were at an increased risk of experiencing a teenage pregnancy (unadjusted hazard ratio [HR] = 2.5, 95% confidence interval [CI]: 1.08–5.96; adjusted HR = 2.7, 95% CI: 1.15–6.34) compared with those with no depression onset. Moreover, compared with those with no depression onset, the risk of pregnancy for girls experiencing depression onset before first sex also increased but was not significant (adjusted HR = 1.5, 95% CI: .82–2.76). Conclusions Timing of first depressive episode relative to age at first sexual intercourse plays a critical role in determining the risk of teenage pregnancy. Timely diagnosis and treatment of depression may not only help adolescents' mental well-being but may also help them prevent teenage pregnancy.

Importance   Millions of low-income children in the United States reside in substandard or unaffordable housing. Relieving these burdens may be associated with changes in asthma outcomes. Objectives   To examine whether participation in the US Department of Housing and Urban Development’s (HUD) rental assistance programs is associated with childhood asthma outcomes and to examine whether associations varied by program type (public housing, multifamily housing, or housing choice vouchers). Design, Setting, and Participants   This survey study used data from the nationally representative National Health Interview Survey linked to administrative housing assistance records from January 1, 1999, to December 31, 2014. A total of 2992 children aged 0 to 17 years who were currently receiving rental assistance or would enter a rental assistance program within 2 years of survey interview were included. Data analysis was performed from January 15, 2018, to August 31, 2019. Exposures   Participation in rental assistance provided by HUD. Main Outcomes and Measures   Ever been diagnosed with asthma, 12-month history of asthma attack, and 12-month history of visiting an emergency department for the treatment of asthma among program participants vs those waiting to enter a program. Overall participation was examined, and participation in public or multifamily housing was compared with participation in housing choice vouchers. Results   This study included 2992 children who were currently participating in a HUD program or would enter a program within 2 years. Among children with an asthma attack in the past year, participation in a rental assistance program was associated with a reduced use of emergency departments for asthma of 18.2 percentage points (95% CI, −29.7 to −6.6 percentage points). Associations were only found after entrance into a program, suggesting that they were not confounded by time-varying factors. Statistically significant results were found for participation in public or multifamily housing (percentage point change, −36.6; 95% CI, −54.8 to −18.4) but not housing choice vouchers (percentage point change, −7.2; 95% CI, −24.6 to 10.3). No statistically significant evidence of changes in asthma attacks was found (percentage point change, −2.7; 95% CI, −12.3 to 7.0 percentage points). Results for asthma diagnosis were smaller and only significant at the 10% level (−4.3; 95% CI, −8.8 to 0.2 percentage points). Conclusions and Relevance   Among children with a recent asthma attack, rental assistance was associated with less emergency department use. These results may have important implications for the well-being of low-income families and health care system costs.
