中国城市独生子女与非独生子女婚前性行为及影响因素研究

Status and influencing factors of premarital sexual behaviour among youth in the cities of China

目的:了解中国城市独生子女与非独生子女婚前性行为发生状况及影响因素,为开展城市青年健康教育提供科学依据。方法:2009年11～12月,采用多阶段随机抽样的方法对北京、保定、西安和黄石等4个城市中年龄20～34岁的1474名独生子女和1808名非独生子女进行入户问卷调查,选取其中1631名未婚者进行分析。结果:①发生婚前性行为比例独生子女为23.6%,非独生子女为27.0%,差异无统计学意义;②初次婚前性行为的年龄为21.27±2.47岁,其中独生子女为21.39±2.77岁,非独生子女为21.15±2.14岁,差异无统计学意义;③多因素分析结果表明,男性、大龄、文化程度低、有异性朋友、无业,以及不与父母同住者更易发生婚前性行为(P<0.05)。结论:中国城市青年的婚前性行为发生比例较高,与其是否为独生子女无关,而与所处的时代及社会环境有关。因此,有关部门应针对城市青年的特点开展有针对性的、系统全面的生殖健康教育。

Objective： To explore differences in the status and influencing factors of premarital sexual behaviours between only children and children with siblings in the cities of China, and provide a basis for health education among youth. Methods ： An anonymous questionnaire survey was conducted among 3 282 youth in four cities in 2009, and the premarital sexual behaviour of 1 631 unmarried youth were analysed. Results： The proportion of the premarital sexual behaviour was 23.7% for only children and 26.3% for children with siblings group, showing no significant difference （P 〉 0. 05 ）. The average age of the first premarital sex was 21.27 ±2. 466 years old for all youth, 21.39 ±2. 771 years old for only children group, and 21.15 ±2. 138 years old for children with siblings group, showing no significant difference （P 〉 0.05 ）. Multivariate analysis showed that men, older persons, and someone with low education level, having boy/girl friend, no job, and living with parents were inclined to have premarital sexual behaviours （ P 〈 0.05 ）. Conclusion： High proportion of the premarital sexual behaviour among youth of the cities in China, whether or not the only child, is found. It maybe associated with the current social environment of modern China. Systematic and comprehensive reproductive health education should be provided to them.
