高校学生避孕节育知信行专题讲座干预效果

目的了解专题讲座对高校学生避孕节育相关知识、态度及相关态度和行为的干预效果,为高校健康促进工作提供参考依据。方法采用分层整群抽样方法对在湖北武汉和重庆2市抽取的8所高校中4 172名参加避孕节育专题讲座的干预组学生和4 943名未参加专题讲座的对照组学生进行避孕节育知识、态度、行为的问卷调查。结果干预组学生干预前避孕节育相关知识和态度的平均得分分别为(58.4±14.15)和(74.54±11.42)分,与同时期对照组的(58.7±14.22)和(74.78±11.13)分比较,差异均无统计学意义(P>0.05);干预后干预组学生避孕节育相关知识平均得分为(63.1±15.56)分,高于同期对照组学生的(59.20±14.83)分,差异有统计学意义(t=-13.40,P<0.001);干预后干预组学生避孕节育相关态度平均得分为(75.74±11.38)分,与同期对照组学生的(75.62±11.21)分比较,差异无统计学意义(P>0.05);干预组与对照组学生近半年内性行为的发生率分别为11.46%和5.28%,差异有统计学意义(χ2=111.09,P<0.001);干预组与对照组学生近半年意外妊娠的发生率分别为12.86%和22.76%,差异有统计学意义(χ2=12.42,P<0.001)。结论避孕节育专题讲座有利于提高学生的避孕节育知识,降低意外妊娠的发生率。

Contraceptive knowledge attitude and behavior after lecture intervention among university students

Objective To evaluate the effects of a lecture intervention on contraceptive knowledge,attitude,and behavior among university students and to provide evidence for health promotion in colleges and universities.Methods A total of 9 203 students were selected from eight universities,of which 4 215 had a lecture on contraceptive knowledge and 4 988 had no intervention.A questionnaire survey on contraceptive knowdedge,attitude and behavior was conducted before and after the intervention among the students.Results Before the intervention,there were no significant differences in the scores of contraceptive knowledge and attitude between the students with and without the intervention(58.4±14.15 vs 45.7±14.22,74.54±11.42 vs 74.78±11.13;P>0.05 for all).After the intervention,the score for contraceptive konwledge in the students with the intervention was significantly higher than that of sdudents without the intervention(63.1±15.56 vs 59.20±14.83,t=13.40;P<0.001).The prevalence of sexual behavior in past six months was significantly higher in the students with the intervention compared to that of students without the intervention(11.46% vs 5.28%,χ2=111.09,P<0.001),but the incidence of accidental pregnancy was significanfly lower for the students with the intervention compared to that of without the intervention(12.26% vs 22.76%,χ2=12.42,P<0.001).Conclusion The lecture inervention on contraceptive knowledge and attitude could improve contraceptive knowledge and lower unplanned pregnancy rate among university students.
