This study examined the associations between social, behavioral, and environmental factors and adolescent parenthood.
We analyzed data from a subsample of participants, 18-30 years of age (n=7,937), who took part in the 2001-2002 National Epidemiologic Study on Alcohol and Related Conditions, a nationally representative survey of adults. An extended Cox proportional hazards model was used to model time until becoming an adolescent parent (i.e., age at which first child was born if < or =18 years). Predictor variables of interest included initiation of alcohol, marijuana, cocaine, and daily cigarette use, age of earliest conduct disorder symptom, having a parent with alcohol and/or drug problems, parental death, divorce and/or separation, race/ethnicity, and gender.
Several variables were associated with adolescent parenthood, including initiation of daily cigarette smoking, age of first antisocial/conduct disorder symptom, and race/ethnicity. Parental alcohol/drug problems and parental death were also associated with adolescent parenthood for women. A significant interaction between initiation of daily cigarette smoking and ethnicity was present for women. Daily cigarette smoking was associated with adolescent parenthood to a greater degree than nondaily cigarette smoking for white and Hispanic women but not African American women. No significant associations were found between adolescent parenthood and initiation of drinking, marijuana, or cocaine and parental divorce/separation.
Prevention efforts should focus on adolescents who are at highest risk of adolescent parenthood.
本研究考察了社会、行为和环境因素与青少年生育之间的关联。
我们分析了参加 2001-2002 年全国酒精和相关条件流行病学研究的参与者的子样本数据,年龄在 18-30 岁之间(n=7937),该研究是一项针对成年人的全国代表性调查。采用扩展的 Cox 比例风险模型来构建成为青少年父母的时间模型(即,如果<或=18 岁,则第一个孩子出生的年龄)。感兴趣的预测变量包括开始饮酒、大麻、可卡因和每日吸烟、最早出现品行障碍症状的年龄、有酗酒和/或吸毒问题的父母、父母死亡、离婚和/或分居、种族/民族以及性别。
几个变量与青少年生育有关,包括开始每日吸烟、首次出现反社会/品行障碍症状的年龄以及种族/民族。对于女性而言,父母的酗酒/吸毒问题和父母死亡也与青少年生育有关。女性中存在每日吸烟开始与种族之间的显著交互作用。对于白人和西班牙裔女性而言,每日吸烟与青少年生育的关联程度大于非每日吸烟,而对于非洲裔美国女性则没有这种关联。青少年生育与饮酒、大麻或可卡因的开始以及父母离婚/分居之间没有显著关联。
预防措施应针对处于青少年生育最高风险的青少年。
