Objective To analyze environmental and social risk factors associated withadolescent obesity by finding out the overweight and obesity prevalence of secondaryvocational school students in Beijing, which aims to propose targeted measures foroverweight and obesity prevention and control among secondary students.Methods Stratified cluster sampling method was used to randomly select30secondary vocational schools from all secondary vocational schools in16districts inBeijing; these30schools were then stratified by grades, and a certain class in each gradewas randomly selected, of which all students were selected as subjects. Questionnairewas used to investigate diet and exercise behaviors of all subjects, and some students andteachers were interviewed. For single variable analysis, t test and χ2test were used forcontinuous and categorical variables respectively, and multivariate logistic regressionanalysis was used to analyze significant factors in single variable analysis.Results The proportion of overweight and obesity were12.2%and9.6%respectively among3924subjects. The proportion of overweight and obesity of boyswere15.6%and12.5%respectively,9.1%and7.0%respectively of girls.Single variable analysis revealed that overweight and obesity prevalence of boyswere both higher than those of girls(x~2=48.86,p<0.001). The proportion of having dessertmore than2times a day in overweight students was smaller than that in ones with normalweight. The proportions of having moderate to vigorous physical activity and playelectronic games more than3hours per day in overweight students were larger than thosein ones with normal weight. The proportions of having breakfast4to6days per week,having dessert2to6times per week and having dessert once a day in obese studentswere smaller than those in ones with normal weight. The proportion of having westernfood each day of7days before the survey in obese students was larger than that in oneswith normal weight. The proportions of having walk4to6days per week and havingwalk everyday in obese students were larger than those in ones with normal weight. Theproportion of playing games less than one hour per day in obese students was smallerthan that in ones with normal weight.Multivariate logistic regression analysis revealed that girls were less likely tobecoming overweight than boys (OR=0.51,95%CI:0.41,0.63). Having dessert morethan2times per week was negatively associated with overweight (OR=0.59,95%CI:0.36,0.96); having moderate to vigorous physical activity4to7days per week waspositively associated with overweight (OR=1.53,95%CI:1.1,2.12;OR=1.62,95%CI:1.12,2.34). Girls were less likely to becoming overweight than boys (OR=0.52,95%CI: 0.41,0.67). Compared with having no dessert each day, having dessert2to6times perweek and having dessert each day were negatively associated with obesityOR=0.68,95%CI:0.48,0.95;OR=0.58,95%CI:0.35,0.95). In7days before the survey,having walk4to7days per week or having bike more than30minutes were positivelyassociated with obesity(OR=1.42,95%CI:1.03,1.94;OR=1.55,95%CI:1.09,2.22).Qualitative interview revealed that the content and schedule of physical activitywere unreasonable, unhealthy eating habits and living environment were prevalent, andstudents had little interest in content and format of current health education. Risk liabilityconcerning sports safety restricted normal conduct of sports activities, and society andfamily put more emphasis on students’academic performance.Conclusion: The obesity intervention should be covered with the whole students,but not only overweight or obese students, the normal students should not be neglected inthis aspect. It would be helpful to set up the accurate health concept for the student fromthe scientific viewpoint. It should pay attention to culture the good life style through thefamily education, and the types of health education in the school should also be diversity.The government, society and family should work together to create the good lifeenvironment for the children and adolescents.
