摘　　要：目的分析安徽省未婚女性月经初潮年龄与首次性行为年龄的关联。方法于2019年4月-2021年6月,在安徽省16个地区妇幼保健机构选取28899名参加婚前检查的未婚女性为调查对象,采用问卷调查获得初潮年龄和首次性行为年龄等相关信息,并采用多因素logistic回归模型分析女性月经初潮年龄与首次性行为年龄的关联。结果安徽省未婚女性月经初潮年龄提前(≤12岁)和推迟(≥15岁)的检出率分别为37.2%和14.0%。首次性行为年龄≤14(过早性行为)、15~17、18~20、≥21岁所占的比例分别为0.2%、4.5%、26.8%和68.4%。多因素logistic回归分析显示,在控制了混杂因素后,与月经初潮年龄正常女性相比,初潮年龄提前组发生过早性行为(OR=2.721,95%CI=1.626~4.533)、15~17岁性行为(OR=1.645,95%CI=1.456~1.860)和18~20岁性行为(OR=1.155,95%CI=1.088~1.227)的风险增加;初潮年龄推迟组发生过早性行为(OR=0.230,95%CI=0.054~0.979),15~17岁性行为(OR=0.573,95%CI=0.465~0.707)和18~20岁性行为(OR=0.812,95%CI=0.745~0.885)的风险降低。结论安徽省女性初潮年龄与婚前首次性行为年龄之间存在显著正向关联。Objective To explore the correlation between age at menarche and age at first sexual behaviors among unmarried women in Anhui province.Methods From the participants of a cohort study(Reproductive Health of Couples of Childbearing Age-Anhui Cohort)conducted during April 2019-June 2021 in 16 districts of Anhui province,we recruited 28899 women(aged 18-49 years)taking premarital examination for their first marriage.Relevant information of the unmarried women were collected with an on-site self-administered questionnaire survey under the help of interviewers.Chisquare test and multivariate logistic regression model were adopted to explore the correlation between age at menarche and age at first sexual behaviors.Results Earlier menarche(at ages of≤12 years)and later menarche(at ages of≥15 years)were reported by 37.2%and 14.0%of the unmarried women.The reported proportions of the women having their first sex at ages≤14,15-17,18-20,and≥21 years were 0.2%,4.5%,26.8%,and 68.4%,respectively.Multivariate logistic regression analysis showed that,after adjusting for potential confounding factors,the women with earlier age at menarche were more likely to have first sexual behavior at ages of≤14(odd ratio[OR]=2.721,95%confidence interval[95%CI]:1.626-4.533),15-17(OR=1.645,95%CI=1.456-1.860),and 18-20(OR=1.155,95%CI:1.088-1.227)compared to the women with normal age at menarche;while,the women with later age at menarche were less likely to have first sexual behavior at ages of≤14(OR=0.230,95%CI:0.054-0.979),15-17(OR=0.573,95%CI:0.465-0.707),and 18-20(OR=0.812,95%CI:0.745-0.885)compared to the women with normal age at menarche,respectively.Conclusion The age at menarche is significantly associated with the age at first sexual behavior among unmarried women in Anhui province.
