With the increased population mobility and the transition in population policy, scholars are quite concerned about family planning/sexual and reproductive health (SRH) and related factors among internal migrant population of reproductive age. Therefore, the proposed study was designed to explore the association between factors related to family planning/SRH and contraceptive use as well as consistent condom use among the above-described population in China.
Cross-sectional study.
Three municipalities in China, namely Beijing, Shanghai and Chongqing.
Among the 6545 participants, 2099, 2414 and 2031 subjects came from Beijing, Shanghai and Chongqing, respectively.
A total of 6545 eligible participants were included as the full sample, 6188 of whom who had intercourse in the last 3 months were selected as the subsample. Among the subsample, 80.88% (5005/6188) adopted any form of contraceptive methods and 49.14% (3041/6188) consistently used condom in the last three sexual intercourses. Meanwhile, the involved participants had a better mastery of knowledge on SRH than on contraception (p<0.0001). The results of the Heckprobit models revealed that the factors associated with both contraceptive use and consistent condom use were relationship with the first intercourse partner, communication frequency with spouse/sexual partners on sex, actual number of children and knowledge on SRH, while knowledge on contraception and age at first intercourse were associated with contraceptive use and consistent condom use, respectively (p<0.05).
In the current study, we revealed a high-level contraceptive prevalence, a relatively low-level consistent condom use and a poor mastery of knowledge on contraception and SRH. The Heckprobit selection model specified the existence of selection bias, providing evidence on the association between the factors on family planning/SRH and contraceptive use as well as consistent condom use, respectively. Our findings indicated that health institutions should offer appropriate technology and high-quality family planning/SRH services for the internal migrant population in China.
随着人口流动的增加和人口政策的转变，学者们非常关注计划生育/性与生殖健康（SRH）以及育龄流动人口的相关因素。因此，本研究旨在探讨中国上述人群中计划生育/SRH 相关因素与避孕措施使用及坚持使用安全套之间的关联。
横断面研究。
中国三个直辖市，即北京、上海和重庆。
在 6545 名参与者中，分别有 2099、2414 和 2031 名来自北京、上海和重庆。
共有 6545 名合格参与者被纳入全样本，其中 6188 名在过去 3 个月内有过性行为的参与者被纳入亚样本。在亚样本中，80.88%（5005/6188）采用了任何形式的避孕方法，49.14%（3041/6188）在过去 3 次性接触中坚持使用安全套。同时，参与研究的人员在 SRH 方面的知识掌握程度要好于避孕方面（p<0.0001）。Heckprobit 模型的结果表明，与避孕措施使用和坚持使用安全套相关的因素包括与第一次性伴侣的关系、与配偶/性伴侣的性沟通频率、实际子女数量和 SRH 知识，而避孕知识和首次性行为年龄与避孕措施使用和坚持使用安全套相关（p<0.05）。
在本研究中，我们发现避孕措施使用率较高，坚持使用安全套的比例较低，且对避孕和 SRH 知识的掌握程度较差。Heckprobit 选择模型表明存在选择偏差，为计划生育/SRH 相关因素与避孕措施使用及坚持使用安全套之间的关联提供了证据。我们的研究结果表明，医疗机构应为中国的流动人口提供适当的技术和高质量的计划生育/SRH 服务。
