To determine if television viewing is associated with the risk of initiating sexual intercourse in young adolescents.
Secondary analysis of data obtained from 1994 through 1996.
The National Longitudinal Study of Adolescent Health.
The 4808 students younger than 16 years who had not initiated intercourse before baseline interview.
Primary exposure was self-reported daily television watching, categorized as low (<2 hours) or high (≥2 hours) use. Secondary exposure was parental regulation of television programming watched.
Main Outcome Measure
Odds ratio for initiating intercourse by 1-year follow-up, adjusted for potential confounders.
At baseline, 2414 (48.8%) subjects watched television 2 or more hours per day. By 1-year follow-up, 791 (15.6%) subjects had initiated intercourse. Sexual initiation was associated with high television use (adjusted odds ratio, 1.35; 95% confidence interval, 1.01-1.79) and lack of parental regulation of television programming (adjusted odds ratio, 1.35; 95% confidence interval, 1.01-1.80). Most subjects (73.8%) reported strong parental disapproval of sex; their overall rate of initiation was 12.5%, and their risk was independently associated with high television use (adjusted odds ratio, 1.72; 95% confidence interval, 1.24-2.40) and lack of parental regulation of television programming (adjusted odds ratio, 1.35; 95% confidence interval, 1.01-1.81). Among adolescents who did not report strong parental disapproval, the rate of sexual initiation was higher (24.1%) but unrelated to television use.
Among young adolescents who reported strong parental disapproval of sex, watching television 2 or more hours per day and lack of parental regulation of television programming were each associated with increased risk of initiating sexual intercourse within a year.
