服务行业未婚流动青少年避孕知识及行为的干预效果评价

摘要

目的:评价在服务行业未婚流动青少年中开展性和生殖健康教育/服务对人群的避孕知识及行为的影响,探讨向未婚流动青少年提供生殖健康教育/服务的适宜模式.方法:将研究对象分为干预组和对照组.干预活动为期半年,仅对干预组对象提供.在干预前后分别开展基线和终末问卷调查.通过两次问卷调查结果来评价干预效果.数据分析用SAS 9.1软件进行.结果:干预组和对照组基线的避孕知识平均得分均＜50分(总分100).干预后,干预组避孕知识得分( 85.51)高于对照组得分(50.38) (P＜0.01).多因素分析结果也显示,干预显著增加了对象的避孕知识得分(B =33.24,P＜0.01).基线调查时,33.33％的干预组对象和59.09％的对照组对象报告在最近3次性行为中每次都使用避孕措施,两者差异具有统计学意义(P＜0.01).终末调查时,干预组对象的这一比例较基线上升(P＜0.05),而对照组则没有改变(P＞0.05).多因素分析显示干预具有促进对象使用避孕措施的趋势(OR=3.06,P＜0.01).结论:干预可提高对象的避孕知识水平,并有促进其避孕措施使用的趋势.提示今后需考虑开展长期、连续的干预,以进一步改善未婚流动青少年的避孕行为.%Objective: To evaluate the effect of sexual and reproductive health education/services on the contraceptive knowledge and behavior among unmarried migrant youths, and to explore a suitable way of provision of reproductive health education/services for these population. Methods; All respondents were divided into the intervention group and the control group. A half - a - year intervention study was only conducted in the intervention group. A baseline survey and a post - intervention survey were conducted among all respondents. The effect of intervention was evaluated by results of the two surveys. SAS 9. 1 software was used for data analyses. Results: The mean score of the contraceptive knowledge in the baseline survey was lower than half of the full mark. After intervention, the mean score in the intervention group (85.51) was much higher than that of the control group (50. 38, P< 0.01). Multi - factor analysis also indicated that the score of contraceptive knowledge significantly increased after intervention (B = 32. 81). In the baseline survey, 33. 33% respondents in the intervention group and 59.09% in the control group reported their contraceptive uses in the last three sexual intercourses. The difference between the two groups was statistically significant (P < 0.01). After intervention, more respondents used contraceptive methods in each sexual intercourse (P < 0.05 ). While there was no significant difference in it between the baseline survey and the post - intervention survey in the control group. Multi - factor analysis showed a tendency that intervention increased the contraceptive use among unmarried migrant youths (OR = 2.33). Conclusion: Intervention can improve contraceptive awareness as well as contraceptive use among unmarried migrant youths. It suggests that a long, continuous intervention should be conducted to improve the contraceptive behavior.
