目的调查商洛市中小学生生活方式及肥胖发生率并分析两者之间的相关关系,为中小学生肥胖预防提供参考依据。方法随机抽取本市8所小学和中学的6 932名学生作为调查对象,测定BMI指数,采用生活方式调查问卷调查中小学生生活方式,分析超重肥胖与生活方式的相关性。结果本市中小学生超重发病率为14.37%,肥胖率为10.69%。城市地区中小学生超重发病率为16.20%,肥胖率为12.71%,农村地区中小学生超重发病率为12.24%,肥胖率为8.34%,经卡方检验,差异有统计学意义(P<0.05)。经多因素非条件Logistic回归分析,喜食甜食、西餐(OR=2.431,95%CI=1.171~5.846)、不爱运动(OR=1.106,95%CI=1.011~2.937)、熬夜(OR=1.347,95%CI=1.102~4.073)和不吃早餐(OR=1.122,95%CI=1.004~1.980)为中小学生超重肥胖的主要危险因素;运动锻炼(OR=0.819,95%CI=0.011~0.979)为中小学生超重肥胖的保护因素。经相关分析,中小学生超重肥胖与西餐食用次数、碳酸饮料食用量呈明显正相关(r=0.736、0.693,P<0.05),与运动锻炼次数呈明显负相关(r=-0.814,P<0.05)。结论商洛市中小学生超重肥胖发病率较高,特别是城区学生发病率最高,与喜食甜食、西餐、不爱运动等不良生活方式明显相关,应该加强体育锻炼,养成健康的生活方式预防超重肥胖。
Objective To investigate the incidence of obesity and the lifestyle of primary and secondary school students in Shangluo City and to analyze the correlation between them and provide a reference for the prevention of obesity in primary and secondary school students. Methods A total of 6 932 students from 8 primary and secondary schools in our city were randomly selected as subjects. The BMI index was measured. Life style questionnaire was used to investigate the lifestyle of primary and secondary school students. The correlation between overweight and obesity and lifestyle was analyzed. Results The prevalence of overweight in primary and secondary school was 14.37% and the obesity rate was 10.69%. The incidence of overweight in primary and secondary school students in urban areas was 16.20%, the obesity rate was 12.71%. The prevalence of overweight in primary and secondary school students in rural areas was 12.24% and the obesity rate was 8.34%. There was significant difference (P <0.05) by chi square test. After multivariate non-conditional logistic regression analysis, they had no symptoms on their favorite foods (OR = 2.431,95% CI = 1.171-5.846), they did not love sports (OR = 1.106,95% CI = 1.011-2.937) , 95% CI = 1.102 ~ 4.073) and no breakfast (OR = 1.122,95% CI = 1.004-1.980) were the main risk factors for overweight and obesity in primary and secondary school children. Exercise training (OR = 0.819, 95% CI = 0.011-0.979 ) For the protection of overweight and obesity in primary and secondary school students. Correlation analysis showed that there was a significant positive correlation between the number of overweight and obesity in middle and primary school students and the number of edible meals and consumption of carbonated drinks (r = 0.736,0.693, P <0.05), but negatively correlated with the numbers of exercise (r = -0.814, P <0.05 ). Conclusion The prevalence of overweight and obesity in primary and secondary school students in Shangluo City is high, especially in urban areas. It is obviously related to unhealthy lifestyles such as eating sweets, western food and unloving sports. Physical exercise should be strengthened to develop a healthy lifestyle to prevent overweight obesity.
