Overweight or obesity relevant knowledge, attitude, and practice among middle school students in Jing'an District, Shanghai

  • 摘要: 目的 了解上海市静安区初中生超重肥胖现状及其知信行状况,为制定相应的干预策略提供依据。

    方法 2015年10月从上海市静安区15所初中随机抽取3所,获取1 100人为调查对象,调查学生基本人口学信息、超重肥胖相关知识和态度、饮食行为、体育活动以及静坐行为等,计算学生的体质量指数(BMI)。

    结果 本次共调查1 100人,回收有效问卷1 089份。1 089名调查对象中,检出超重82人,超重率为7.5%,肥胖112人,肥胖率为10.3%;其中男生超重和肥胖率均高于女生(12.1%、12.6% vs 3.6%、8.2%,P分别为0.017和0.001)。关于肉类、饮水、快餐等营养知识的知晓率女生高于男生,认为肥胖对健康危害较大,想改变体重的比例女生高于男生(P < 0.05)。21.0%体重正常组的学生认为自己的体形属于有点胖或胖;41.3%(449/1 088)的初中生对自己的体重不满意或比较不满意;63.0%(685/1 088)的初中生想改变自己的体重状况;76.5%(833/1 089)的初中生相信通过自己的努力能达到理想的体重。初中生喝饮料者占比35.4%。在过去7日中,有90.1%的初中生进行过中等强度的运动;初中生学习日课外静坐时间平均为2.90 h/d,周末或假期静坐时间平均为4.95 h/d。

    结论 静安区初中生肥胖检出率较高,部分学生对自己的体形评价不客观,静坐时间较长,有关部门应给予重视。

     

    Abstract: Objective To understand the overweight or obesity status and relevant knowledge, attitude, and practice (KAP) among middle school students in Jing'an District, Shanghai, and to provide evidence for intervention.

    Methods Three schools were randomly selected out of 15 middle schools in Jing'an District, Shanghai, and a total of 1 100 students were enrolled in this study. A questionnaire survey was conducted to collect demographic information, overweight & obesity related knowledge and attitude, dietary behavior, physical exercise, and sedentary behavior. Body mass index (BMI) was calculated.

    Results A total of 1 089 completed questionnaires were collected out of 1 100 participants. Among them, 7.5% (n=82) and 10.3% (n=112) students were overweight and obese respectively. The rates of overweight (P=0.017) and obesity (P=0.001) were all significantly higher in boys (12.1%, 12.6%) than in girls (3.6%, 8.2%). More girls had knowledge on meat, drinking water, and fast food than boys, believed that obesity is harmful to health, and wanted to lose weight (P < 0.05). Besides, 21.0% students without overweight or obesity considered themselves as slightly overweight; 41.3% (449/1 088) students were not satisfied with their body weight; 63.0% (685/1 088) students wanted to improve their weight status; 76.5% (833/1 089) students believed that they can achieve an ideal weight through their own efforts. Moreover, 35.4% students drank beverages. In the post seven days, 90.1% of the students had moderate-intensity physical activity; the daily average sedentary time for the students was 2.90 h/d and 4.95 h/d during extracurricular time in workdays and on weekends/holidays respectively.

    Conclusion The obesity rate of the middle school students is relatively high in Jing'an District. Some students do not have an objective assessment of their body shape. They also report excess sedentary time. Therefore, relevant departments should pay attention to such phenomenon.
