Background: Body mass index of adolescents and children has risen rapidly so that the overweight and obesity rate has been significantly increased in social life, and it is now widely regarded as a serious global public health problem.
Objectives：This present study aimed to identify prevalence of factors associated with overweight and obesity among 12–15-year-old adolescents and children in Longnan City, Gansu Province.
Methods：A total 620 of students from Nine schools in Longnan City were selected and questionnaire survey was done in each school. Participants were selected as students from each school to investigate the influencing factors associated with overweight and obesity among them. Multiple logistic regression model considering backward elimination has been used for analysis.
Results: A total of 620 adolescents and children were investigated in this study. Multiple logistic regression model results demonstrated that the risk of obesity was higher in males (AOR=3.47，95% CI:2.27-5.31) than in females. Statistically, eating fast food (AOR=1.65，95% CI:1.05-2.58), chocolate (AOR=2.07, 95% CI:1.31–3.27) ，not participating in weekly exercise (AOR=1.58，95% CI:1.05–2.39), lack of weekly exercise time (AOR=2.75，95% CI:1.20–6.31), and not eating fruit (AOR=1.53，95% CI:1.01–2.32) were significantly associated with childhood obesity. Children living in cities (AOR=1.80, 95% CI:1.20–2.70) were more likely to be obese than those living in rural areas, and that children with a family genetic history of obesity (AOR=2.20，95% CI:1.36–3.56) were also at risk of developing obesity.
Conclusion：In Longnan City, boys are more prone to be obese than girls. Eating behavior, number of exercises, length of exercise, area of residence and family genetic history are the main influencing factors for overweight and obesity in adolescents and children. Raising awareness, promoting healthy eating habits, and implementing policies are crucial to prevent and reduce overweight and obesity among adolescents and children.
