青少年戒烟的信息通信技术干预短期效果评价

Short-term Effectiveness of an Adolescent Smoking Cessation Program by Using Information Communication Technologies

目的了解信息通信技术对青少年戒烟干预的短期效果,为开展青少年戒烟干预活动提供参考。方法在上海市6所中专和职业高中募集179名吸烟青少年,以学校为单位随机分成干预组和对照组,进行为期3个月的干预研究。对干预组利用手机短信、即时通信和互联网等信息通信技术实施戒烟干预,而对照组接受戒烟宣传手册自行阅读。通过干预前后烟草相关知识、态度、吸烟行为、尼古丁和烟草依赖指数等的变化评价干预实施的短期效果。结果 12周后,干预组对于烟草的部分知识和态度增强程度高于对照组;干预组的7d和30d戒烟率分别达到14.1%和9.8%,高于对照组的8.0%和6.9%。干预组的日均吸烟量平均减少4.1支,而对照组平均减少1.9支,干预组减少吸烟率(66.3%)显著高于对照组(34.5%),尤其表现在与朋友相处时减少了吸烟行为;行为改变阶段分析显示,63.2%的干预组对象朝着成功戒烟方向前进,而对照组为34.8%。期间干预组的尼古丁依赖指数和烟草依赖指数分别下降了0.5和3.8,而对照组却分别上升了0.3和1.6。结论运用手机短信等现代信息通信技术进行双向、互动的青少年戒烟干预,可以有效提高对戒烟的认同感,减少吸烟量和对烟草的身心依赖。
