【摘要】：[目的]分析干预前后青少年视屏行为的改变,评估干预的效果及其影响因素。[方法]随机抽取上海市2个区,从该2个区所有学校中随机选择2所学校的预初及初一年级学生,其中1所为干预组,另1所为对照组,干预组1年内实施以健康教育为主的综合干预措施,对照组无干预措施。1年后对两校再进行调查,观察干预效果。[结果]知识方面,干预组"过长视屏时间对健康影响"的回答正确率(87.1%)高于对照组(81.7%)(P0.01),其余知识项目差异无统计学意义。干预组和对照组干预前后视屏时间差值比较,差异无统计学意义。[结论]总体目标行为改变没有完全达到预期的效果,这与干预过程中受到的各种限制有关,并且在一定程度上说明了青少年课余视屏行为发生过程和干预的复杂性。
[Abstract]:Objective: to analyze the changes of video-screen behavior of adolescents before and after intervention, and to evaluate the effect of intervention and its influencing factors. [methods] two districts of Shanghai were randomly selected from all the schools in these two districts to choose the students of pre-primary and junior high grades randomly, one of them was the intervention group, the other one was the control group, and one of them was the intervention group, and the other one was the control group. The intervention group carried out comprehensive intervention with health education in one year, while the control group had no intervention, and then investigated the two schools one year later to observe the effect of intervention. [results] in terms of knowledge, the correct answer rate of the intervention group (87.1%) was higher than that of the control group (81.7%). There was no significant difference in other knowledge items. There was no significant difference between the intervention group and the control group before and after intervention. [conclusion] the overall goal behavior change did not reach the expected effect completely, which was related to the various restrictions in the process of intervention, and to some extent explained the process of occurrence and the complexity of intervention in teenagers' after-school video screen behavior.
