基于IMB模型的上海市女性流动人口生殖健康干预效果评价

Evaluation of reproductive health intervention based on IMB model among femalemigrants in Shanghai

目的评价基于信息—动机—行为技巧(IMB)模型对女性流动人口生殖健康的干预效果。方法在上海市浦东新区随机选择200名女性外来务工人员,随机分为干预组和对照组(n=100),在干预前和干预后2周分别对两组人群进行生殖健康问卷调查。干预组行基于IMB模型的生殖健康干预,内容包括生殖健康和获得性免疫缺陷综合征(AIDS)相关信息、动机和行为技巧等。结果干预组和对照组分别有96人和92人完成了问卷调查。干预后,干预组的生殖健康信息得分从9.12±1.91提高到12.22±1.51(P<0.05),其中AIDS非传播途径、安全套防病作用及性病知识得分明显提高,对待婚前和婚外性行为的态度持反对意见者明显增多,赞同安全套使用和与伴侣沟通使用者人数也明显增多(P<0.05);最近一次性行为的安全套使用率从35.0%提高到53.1%,2周坚持使用安全套的对象从8.0%上升到27.1%(P<0.05)。结论本次基于IMB模型的生殖健康干预效果显著,提高了女性流动人口的生殖健康信息水平和预防行为技巧,同时减少了高危行为动机。

Objective To evaluate the effect of reproductive health intervention based on the Information-Motivation- Behavioral Skills model （IMB） among female migrants in Shanghai. Methods A total of 200 female migrants from Pudong New Area were randomly recruited and divided into intervention group and control group, with 100 female migrants in each group, and questionnaire survey was conducted in two groups before intervention and 2 weeks after intervention. Reproductive health intervention based on IMB model was carried out in intervention group, which included reproductive health and acquired immune deficiency syndrome （AIDS） related information, motivation and behavior skills. Results Ninety-six female migrants in intervention group and 92 female migrants in control group completed the questionnaire survey. After intervention, the score of reproductive health information increased from 9.12 ± 1.91 to 12.22 ± 1.51 in intervention group （ P 〈 0.05）, the scores of knowledge of AIDS non-transmission, sexual transmitted infection and disease prevention by using condom significantly improved, more female migrants held the attitude against premarital sex and extramarital affair, and more agreed with condom use and discussion about condom use with sexual partner （ P 〈 0. 05）. The condom use rate increased from 35.0% to 53.1% in the recent sexual intercourse, and the consistent condom use rate in two weeks also improved from 8.0% to 27.1% in intervention group （P 〈 0. 05）. Conclusion The reproductive health intervention based on IMB model is effective, which may improve the reproductive health information, reduce high risk behavior motivation andimprove the preventive behavior techniques among female migrants in Shanghai.
