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 (> or =2 hours) use. Secondary exposure was parental regulation of television programming watched.
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.
确定青少年观看电视是否与过早开始性行为的风险相关。
对1994年至1996年获取的数据进行二次分析。
青少年健康全国纵向研究。
4808名16岁以下且在基线访谈前未开始性行为的学生。
主要暴露因素为自我报告的每日看电视时间，分为低（<2小时）或高（≥2小时）使用量。次要暴露因素为父母对所观看电视节目的监管。
随访1年时开始性行为的比值比，并对潜在混杂因素进行校正。
在基线时，2414名（48.8%）受试者每天看电视2小时或更长时间。到随访1年时，791名（15.6%）受试者开始了性行为。开始性行为与大量看电视（校正后的比值比为1.35；95%置信区间为1.01 - 1.79）以及父母对电视节目缺乏监管（校正后的比值比为1.35；95%置信区间为1.01 - 1.80）相关。大多数受试者（73.8%）报告父母强烈反对性行为；他们的总体开始率为12.5%，其风险独立地与大量看电视（校正后的比值比为1.72；95%置信区间为1.24 - 2.40）以及父母对电视节目缺乏监管（校正后的比值比为1.35；95%置信区间为1.01 - 1.81）相关。在未报告父母强烈反对性行为的青少年中，性行为开始率较高（24.1%），但与看电视情况无关。
在报告父母强烈反对性行为的青少年中，每天看电视2小时或更长时间以及父母对电视节目缺乏监管均与1年内开始性行为的风险增加相关。
