Our objective was to determine if sexual orientation groups differ in accuracy of BMI (kg/m(2)) calculated from self-reported height and weight and if weight status modifies possible differences. Using gender-stratified multiple linear regression to analyze Wave III of the National Longitudinal Study of Adolescent Health (n = 12,197), we examined the(More)
Previous studies have observed that television (TV) viewing is predictive of obesity and weight gain. We examined whether the cross-sectional association between TV viewing and BMI varied by racial/ethnic subgroups among young women in Wave III (collected in 2001-2002) of the National Longitudinal Study of Adolescent Health. We used multivariate linear(More)

Depressed young people may have sexual intercourse (sex) to regulate their disordered affective states. This study sought to determine how momentary positive and negative affect relate to subsequent sex events in depressed adolescents and young adults. Fifty-four outpatients (87% female) 15-22 years who reported clinically significant depressive symptoms(More)
PURPOSE To examine daily- and event-level associations of substance use with occurrence of sex and condom nonuse among depressed youth.

We investigated the contribution of school environmental factors to individual and school variation in disordered weight control behaviors (DWCB). Analyses were based on self-report data gathered from 18,567 middle-school students in 2005 and publicly available data on school characteristics. We observed large differences across schools in percent of(More)
STUDY OBJECTIVE Depressed young women are at particularly high risk of sexually transmitted infections (STIs), yet little is known about their condom use practices. This study sought (1) to describe condom use errors among depressed adolescent and young adult women and (2) to identify event- and individual-level correlates of incorrect use. DESIGN(More)
