Longitudinal data were used to explore relations between teenage pregnancy, sexual behaviour, and family type. The study examined whether students from lone parent and/or teenage mother initiated families more commonly report sex, lack of contraception at first sex, and/or conceptions by age 15/16, and whether such associations can be explained by low parental strictness, difficult parent-child communication, and/or low parental input into sex education. Up to date longitudinal UK research on family influences on conceptions is lacking, as is longitudinal research on family influences on sexual behaviour. No previous studies have comprehensively examined effects of parenting behaviours. Unlike previous research, this study tested theories suggesting that parenting deficits among lone parent and teenage initiated families increase risk of teenage pregnancy among their children.
Secondary analysis of data from a trial of sex education.
Girls and boys from lone parent families or having mothers who were teenagers when they were born were more likely to report sex but not lack of contraception at first sex by age 15/16. Girls and boys with mothers having them as teenagers, and boys but not girls from lone parent families, were more likely to report being involved in conceptions by age 15/16. Only the association between teenage mother family and girls' conceptions was reduced by adjusting for a parenting behaviour measure.
Students from lone parent families or having mothers who were teenagers when they were born are more likely to report early sexual debut and conceptions by age 15/16, but this is not generally explained by parenting style.
利用纵向数据探讨青少年怀孕、性行为与家庭类型之间的关系。该研究调查了来自单亲家庭和/或少女母亲组建家庭的学生是否更常报告有性行为、首次性行为时未采取避孕措施以及/或者在15/16岁时怀孕,以及这种关联是否可以通过父母管教宽松、亲子沟通困难和/或父母在性教育方面投入不足来解释。英国目前缺乏关于家庭对怀孕影响的纵向研究,也缺乏关于家庭对性行为影响的纵向研究。以前没有研究全面考察过养育行为的影响。与以往研究不同的是,本研究对一些理论进行了验证,这些理论认为单亲家庭和少女组建家庭中养育方面的缺陷会增加其子女青少年怀孕的风险。
对一项性教育试验的数据进行二次分析。
来自单亲家庭或母亲在生育时为青少年的女孩和男孩更有可能报告有性行为,但在15/16岁时首次性行为时并非未采取避孕措施。母亲在青少年时期生育的女孩和男孩,以及来自单亲家庭的男孩(而非女孩)在15/16岁时更有可能报告自己参与了怀孕。通过调整养育行为指标,只有少女母亲家庭与女孩怀孕之间的关联有所减弱。
来自单亲家庭或母亲在生育时为青少年的学生在15/16岁时更有可能报告过早开始性行为和怀孕,但这一般不能用养育方式来解释。
