| Objective:To understand the status of school-age children’s overweight and obesity in Yiwu, to explore related influencing factors causing overweight and obesity in school-age children, then discuss the relationship between school-age children overweight and obesity and the factors; which bases itself on "The Definition and Clinical Practice Recommendation of Metabolic Syndrome in Chinese Children and adolescents" (Recommendation for short), primarily by adjusting the diet, increase physical activity, change bad behavior and other integrated intervention measures to control weight, then evaluate the effect after the intervention, explore mode of intervention to control overweight and obesity in school-age children, and finally provide scientific opinions in order to prevent children’s overweight and obesity.Methods:(1) Prevalence survey, stratified random cluster sampling method is used.The parents of school-age children were randomly selected from two primary schools in Yiwu and then surveyed against "The Growth Status of School-age Children Assessment Questionnaire ". The questionnaire contains 5 aspects, which fall into the following categories:a general situation of children, birth status, diet, exercise and daily life situations, general condition of parents and families, family history of genetic condition. Those factors are analyzed through SPSS20.0, chi-square test and binary logistic regression.(2) Experiment method.119 overweight and obesity school-age children in Yiwu Chaoyang primary school were selected, who were randomly divided into intervention group (55) and control group (64). The intervention group used personalized and integrated measures, based on family-school seminars, teachers’ interviews, hospital’s diet, exercise instruction, in order to establish a healthy lifestyle and eating habits, while the control group went on their normal way of life. Related health indicators were compared before and after the intervention and the effect of the intervention was evaluated.Results:(1) 564 school-age children were surveyed,159 overweight and obese children, resulting in a 28.19% of total detection rate,71 boys (44.65%) and 88 girls (55.35%).(2) According to the results, school-age children’s overweight and obesity is associated their age, parents who think their children’s size, the average monthly increase, appetite, whether they like to eat meat, drink milk, take in staple food, do exercise, practice martial arts (including tai chi, taekwondo), their parents’BMI, father’s occupation, history of diabetes or obesity within three generations. According to the results of binary logistic regression analysis, older children are found to be related with overweight and obesity (OR= 0.417); parents who think their children thin and fat are more prone to overweight and obesity (OR values were 0.078 and 19.598); meat-lovers are related to overweight and obesity (OR= 1.949), so are milk-drinkers (OR= 2.816) and martial practicers (like tai chi, taekwondo, or others) (OR= 4.043). Children whose mother’s BMI is 24 or greater are related to overweight and obesity (OR= 2.063).(3) One year later, the two groups have shown differences. The BMI z scores of the intervention group are significantly getting smaller while the BMI z scores of control group show no significant difference. When the detection ration of overweight drops in both groups, it plunges even more in the intervention group.Conclusions:(1) Detection rate of school-agers’overweight and obesity was found higher in the survey; the main adverse influencing factors are parents who think their children fat, like to eat meat, drink milk, do martial arts (including Tai Chi, Tae kwon do, etc) and their mother’s BMI(>24 kg/m2).10 years and older, and parents who think their children thin body, are maintaining a proper weight of protective factors.(2) The intervention programs based on family-school-hospital model and the guidance of The Recommendations are effective in preventing and treating overweight and obesity in school-age children. |
