title: Depressive symptoms as a longitudinal predictor of sexual risk behaviors among US middle and high school students.
abstract: OBJECTIVE
  The purpose of this study was to examine whether depressive symptoms are predictive of subsequent sexual risk behavior in a national probability sample of US middle and high school students.
  
  
  METHODS
  Sexually active, unmarried, middle and high school students (n = 4152) participated in home interviews in waves I and II of the National Longitudinal Study of Adolescent Health, at an approximately 1-year interval. Associations between baseline depressive symptoms and sexual risk behaviors over the course of the following year were examined separately for boys and girls, adjusting for demographic variables, religiosity, same-sex attraction/behavior, sexual intercourse before age 10, and baseline sexual risk behavior.
  
  
  RESULTS
  In adjusted models, boys and girls with high depressive symptom levels at baseline were significantly more likely than those with low symptom levels to report > or = 1 of the examined sexual risk behaviors over the course of the 1-year follow-up period. For boys, high depressive symptom levels were specifically predictive of condom nonuse at last sex, birth control nonuse at last sex, and substance use at last sex; these results were similar to those of parallel analyses with a continuous depression measure. For girls, moderate depressive symptoms were associated with substance use at last sex, and no significant associations were found between high depressive symptom levels and individual sexual risk behaviors. Parallel analyses with the continuous depression measure found significant associations for condom nonuse at last sex, birth control nonuse at last sex, > or = 3 sexual partners, and any sexual risk behavior.
  
  
  CONCLUSIONS
  In this study, depressive symptoms predicted sexual risk behavior in a national sample of male and female middle and high school students over a 1-year period.
