Abstract
OBJECTIVES: We examined the prospective association between negative life events and time to initiation of sexual intercourse and the influence of family structure and family income on this association. METHODS: We followed up a randomly selected sample (n=649) of ethnically diverse parents and their children aged 12 to 17 years over a 5-year period. We conducted Cox proportional hazards regression analysis to examine the relation between negative life events and time to initiation of sexual intercourse. Family structure and family income were assessed as confounders. RESULTS: Negative life events were significant predictors of time to initiation of sexual intercourse in adolescents. After controlling for demographic variables, youths reporting 1 negative life event had a hazard of initiation of sexual intercourse 1.40 times greater and youths reporting 2 or more negative life events had a hazard of initiation of sexual intercourse 1.61 times greater compared with youths reporting no negative life events. Family structure and family income were not significant confounders of the relation between initiation of sexual intercourse and negative life events. CONCLUSIONS: Interventions to prevent initiation of sexual intercourse should focus on youths with recent negative life events, regardless of family income and structure.
