소아 비만과 부모 비만과의 관련성에 대한 연구 - 서울지역 일부 국민학생과 그 부모를 대상으로 -

Abstract

Background : An obese child had a high risk for becoming an obese adult and many obese children have disorder similar to obese adults. In addition, obese adolescence is refractory to trerapy due to not hypetrophy of adipocyte but hyperplasia of that. So in obesity, prevention at childhood is the best choice of treatment. Factors that affect the childhood obesity are classified into genetic and environmental factors. Familial tendency or aggregation that includes the both sides of these factors is well known. The purpose of this study is to observe the relationship between child obesity and parents' obesity.

Methods : In 332 boys, 316 girls at 10-11 years old of elementary school in seoul, height and weight was measured in April, 1994. Their parents' height, weight and demographic datas were collected by using the self-recorded home questionnaire. Obesity is evaluated by body mass index(BMI=kg/m²). In children, BMI≥85 percentile was defined as obese group and 25-75 percentile was defined as normal weight group. In parents, BMI≥85 percentile was obese group and ≤85 percentile was non-obese group.

Results : Mothers' BMI was significantly(P<0.05) higher in child obese group than child normal-weight group. In child obese group, children's BMI correlated closely with their mothers' BMI(r=0.23, P<0.05). Children with obese mothers were about twice as likely to be obese than children of non-obese mothers state of each parent was significantly(P<0.01) different.

Conclusion : In child obese group, children's BMI was related more closely with mothers' BMI than the fathers'. Maternal obesity can be one of the risk factors for child obesity.
