Objective To analyze the related influencing factors and control strategies of childhood obesity and its impact on the incidence of diabetes,so as to provide theoretical basis for the prevention and control of childhood obesity. Methods Totally 836 children who were examined in Fifth Hospital of Shenyang from May 2012 to January 2018,were studied as subjects.The incidence of obesity in the subjects was investigated,and the correlations between the sex,age,school and life habits of all the subjects and the incidence of obesity were analyzed.Obese children were treated as the observation group and normal children were used as control group.The differences on fasting blood glucose,postprandial 2 h blood glucose(2 h PBG),impaired fasting glucose(IFG),glucose tolerance(IGT) and diabetes incidence were compared between the two groups. Results Of the 836 children,89 were obese,231 children were overweight,516 children had normal BMI index,and the incidence of obesity was 10.65%.The main factors affecting childhood obesity were sex(OR=6.415,95%CI:2.714~12.684,P=0.027),age(OR=9.328,95%CI:2.413~10.152,P=0.003),residence (OR=6.413,95%CI:2.748~8.503,P=0.015),breakfast location(OR=6.349,95%CI:2.692~8.419,P=0.009),weekend activity time(OR=14.928,95%CI:4.210~15.384,P<0.001).Thelevel of FPG and 2 hPBG of the observation group were significantly higher than those of the control group(P<0.05),and the incidence of IFG,IGT and diabetes in the observation group were significantly higher than those in control group(P<0.05). Conclusions The occurrence of childhood obesity is closely related to many factors in the outside world and itself.Moreover, obesity may also induce diabetes,which threatens the safety of children.Clinically,the specific factors that induce the development of childhood obesity should be controlled.thereby ensuring the healthy growth of children and improving their quality of life.
