Adolescent sexual behaviors are a significant public health concern because of the risks of STDs and the negative social consequences of teenage pregnancies. Associations between neighborhood characteristics and adolescents' initiation of sex and contraceptive use are poorly understood.
Multilevel logistic regression analyses of data from 14,151 adolescents in grades 7-12 in Wave 1 of the National Longitudinal Study of Adolescent Health examined the relationships between four neighborhood dimensions (socioeconomic characteristics, norms and opportunity structure, social disorganization, and racial and ethnic composition) and the initiation of sex and contraceptive use at first and most recent sex. Individual- and household-level covariates were family income, parental education, race and ethnicity, age and family structure. Multivariate analyses were stratified by gender.
All four dimensions of neighborhood context were independently associated with sexual initiation. For females, living in a neighborhood with a greater concentration of youth who were idle or black residents was associated with increased odds of sexual initiation, whereas a greater concentration of married households or Hispanic residents was associated with decreased odds of initiation. Higher initiation among males was associated with a higher concentration of poverty or idle youth, while lower initiation was found with a higher concentration of affluent households or working women. The sole association with contraceptive use was that females in neighborhoods with more idle youth had a reduced likelihood of having used contraceptives at first sex.
Neighborhood context appears to be modestly associated with the sexual initiation of adolescents. However, little support was found for neighborhood influence on contraceptive use, suggesting that other factors may play a more important role in shaping adolescents' contraceptive behaviors.
青少年性行为是一个重大的公共卫生问题,因为存在性传播疾病风险以及少女怀孕带来的负面社会后果。邻里特征与青少年开始性行为及使用避孕药具之间的关联尚不清楚。
对全国青少年健康纵向研究第一轮中7至12年级的14151名青少年的数据进行多层次逻辑回归分析,研究四个邻里维度(社会经济特征、规范和机会结构、社会失序以及种族和民族构成)与首次及最近一次性行为时开始性行为及使用避孕药具之间的关系。个体和家庭层面的协变量包括家庭收入、父母教育程度、种族和民族、年龄及家庭结构。多变量分析按性别分层。
邻里环境的所有四个维度均与开始性行为独立相关。对于女性而言,居住在闲散青年或黑人居民集中度较高的社区与开始性行为的几率增加相关,而已婚家庭或西班牙裔居民集中度较高则与开始性行为的几率降低相关。男性中较高的开始性行为几率与贫困或闲散青年的较高集中度相关,而在富裕家庭或职业女性集中度较高的社区中开始性行为的几率较低。与使用避孕药具唯一的关联是,在闲散青年较多的社区中,女性首次性行为时使用避孕药具的可能性降低。
邻里环境似乎与青少年开始性行为存在适度关联。然而,几乎没有发现邻里环境对使用避孕药具的影响,这表明其他因素可能在塑造青少年的避孕行为方面发挥更重要的作用。
