Inspite of unquestionable progress, the protection of girls at first sexual intercourse is still not perfect. The main risks are well known (sexually transmitted infections [STIs], unwanted pregnancies, psychological consequences) and seem to be higher in the case of early sexual initiation. The aim of this epidemiological study is to analyse factors associated with early heterosexual intercourse (age 15 or before) among girls, considered as risk factors for pregnancies and STIs.
Our data come from the 2002 international survey Health Behaviour in School-aged Children (HBSC)/WHO. The questionnaire is completed anonymously in class and measures health, health behaviours and their contexts among 11-, 13- and 15-year-old students. Only the 15 year-olds are asked about their sexual behaviour. In France, 1264 15-year-old (plus or minus six months) girls have answered the survey.
Two hundred and twenty-four girls (17,7 %) state they have already had sexual intercourse. Among these, 88,4 % say that condoms and/or pills were used at last sexual intercourse. Multivariate analysis (n=1159) show that seven variables are significantly and independently linked to a higher frequency of early sexual intercourse: single-parent or reconstructed family, repeated drunkenness, daily smoking, cannabis experimentation, frequent evenings out, negative life appreciation and early menarche.
Identifying factors associated with early sexual initiation should help professionals to better take care of those high risk adolescent girls.
尽管取得了毋庸置疑的进展，但对首次发生性行为的女孩的保护仍不完善。主要风险众所周知（性传播感染、意外怀孕、心理影响），而且在过早开始性行为的情况下这些风险似乎更高。这项流行病学研究的目的是分析与女孩过早发生异性性行为（15岁及以下）相关的因素，这些因素被视为怀孕和性传播感染的风险因素。
我们的数据来自2002年国际学龄儿童健康行为调查（HBSC）/世界卫生组织。问卷在课堂上匿名填写，调查11岁、13岁和15岁学生的健康状况、健康行为及其背景。仅对15岁的学生询问其性行为情况。在法国，1264名15岁（上下相差6个月）的女孩回答了该调查。
224名女孩（17.7%）表示她们已经有过性行为。其中，88.4%的人说在最近一次性行为中使用了避孕套和/或避孕药。多变量分析（n = 1159）显示，有七个变量与过早性行为的较高发生率显著且独立相关：单亲或重组家庭、反复醉酒、每日吸烟、尝试大麻、频繁外出过夜、对生活评价消极以及初潮过早。
识别与过早开始性行为相关的因素应有助于专业人员更好地照顾那些高危青春期女孩。
