上海市青少年课余屏前时间与肥胖的关系

Association between Screen Time and Obesity among Middle School Students in Shanghai

  • 摘要: 目的 分析上海市初中学段青少年屏前时间与肥胖的关系,为开展干预提供依据。

    方法 采取二阶段随机抽样的方法。2011年抽取上海市9所中学初中部的学生及其家长为研究对象,共收到有效问卷为4 196份,利用体检信息进行营养状况评价。观察其屏前时间,并采用二分类logistic回归,分析过长屏前时间与肥胖的关系。

    结果 51.5%的学生有过长屏前时间。在控制了年龄、性别、膳食行为、睡眠、体力活动、出生体质量和父母的营养状况后,过长屏前时间与肥胖相关,非过长屏前时间相对于过长时间的OR值为0.779。

    结论 过长的屏前时间是青少年肥胖的影响因素,需要进一步开展对过长屏前行为影响因素的研究,为开展干预工作提供证据。

     

    Abstract: Objective To assess the association between screen time and obesity among middle school students in Shanghai, and to provide evidence for intervention.

    Methods Middle school students aged 9 to 16 years and their parents were recruited by a two-stage sampling technique in Shanghai, 2011. A structured questionnaire was used to collected information on screen time and related risk factors, and a total of 4 196 questionnaires were valid. A nutrition evaluation was conducted based on data from physical examinations. A logistic regression model was developed to determine the contribution of screen time to obesity.

    Results Of the 4 196 students investigated, 51.5% students reported extra screen time. Adjusting for age, sex, dietary behavior, sleep, physical activity, birth weight, and the nutritional status of parents, the screen time of students was associated with obesity, and the OR value of obesity in students with normal screen time versus students with extra screen time was 0.779.

    Conclusion The extra screen time is associated with obesity. Studies on the risk factors of extra screen time are necessary to inform developing intervention programs in the future.
