目的 了解影响中学生青少年肥胖的因素,并为以后肥胖症的研究和防治提供依据。方法 2019年3月在昌吉市随机抽取一所中学,以新疆昌吉市某中学12~15岁学生作为调查对象按照学号随机抽取330名学生进行生活方式的调查,并分析与肥胖的关系。结果 肥胖检出人数为17人,检出率5.3%。肥胖学生与非肥胖学生在是否经常食用烧烤和油炸食品、汉堡炸鸡等快餐、作业量多少、学习生活中的疲劳感和每周40 min以上的课余体育锻炼差异均有统计学意义(χ2=20.219、41.398、32.103、12.359、19.608,P <0.05)。二分类Logistic回归分析显示,每周食用3 d及以上汉堡炸鸡等快餐(OR=1.766,95%CI:1.018~3.061,P=0.043),每周食用3 d及以上食用烧烤和油炸食品(OR=2.230,95%CI:1.125-4.419,P=0.022)是肥胖发生的危险因素;较少的课后家庭作业量为肥胖发生的保护因素(OR=0.397,95%CI:0.174~0.904,P=0.028)。结论 中学生不良饮食行为和作业量多少与肥胖存在相关关系,应培养学生形成良好的饮食习惯,相应减少作业量以降低肥胖的发生,促进其健康成长。
Abstract
Objective To understand the factors affecting adolescent obesity in middle school students, in order to provide information for future research and prevention of obesity. Methods In March 2019, a middle school was randomly selected from a middle school in Changji City, Xinjiang. Totally 330 students aged 12 to 15 years in this school were randomly selected according to the school number to investigate their lifestyle. The relationship between life style and obesity was analyzed. Results The detection rate of obese adolescents was 5. 3% (17/330). There were significant differences on the proportions of unhealthy food (such as barbecue and fried food), fast food (such as hamburger fried chicken), homework quantity, fatigue in study and life, and more than 40 minutes of extracurricular physical exercise between obese students and non-obese students(χ2=20. 219, 41. 398, 32. 103, 12. 359, 19. 608, P<0. 05). Binary Logistic regression analysis showed that eating of fast food such as hamburger fried chicken three days or more per week(OR=1. 766,95%CI:1. 018-3. 061,P=0. 043), eating barbecue and fried food three days or more per week(OR=2. 230,95%CI:1. 125-4. 419,P=0. 022)were the risk factors for adolescent obesity, while less homework after class was a protective factor (OR=0. 397, 95%CI:0. 174-0. 904,P=0. 028). Conclusions The bad eating behavior and work quantity of middle school students are related to adolescent obesity. Students should be trained to form good eating habits, reduce the amount of work accordingly in order to reduce the occurrence of obesity and promote their healthy and good growth.
