Abstract

Objective: Parental obesity has been identified as a predominant risk factor for childhood overweight and obesity. We investigated the relationship between parent and child obesity in South Korea, particularly linked with varying family structures.
Subjects and methods: Data for households with children aged 2–18 years were taken from the pooled data of the Korea National Health and Nutrition Examination Survey (KNHANES) 2007–2010 conducted by the Korea Centers for Disease Control and Prevention (KCDC). The sample consisted of 17 453 individuals (7879 children and 9574 adults) from 5048 households with children for this study. Children’s overweight and obesity prevalence was compared using both International Obesity Taskforce (IOTF) and KCDC cutoff points according to parental weight status and household structure. Logistic regression analysis was used.
Results: Significantly greater odds of overweight and obesity existed among children living with both parents (odds ratio (OR)=3.5, 95% confidence interval (CI): 2.71, 4.65) or one parent (mother: OR=1.6, 95% CI: 1.22, 2.12; father: OR=1.7, 95% CI: 1.37, 1.99). The adjusted ORs for overweight and obesity among children living with overweight mother only or overweight grandparent only were approximately double that of children living with normal-weight mother (OR=2.2, 95% CI: 1.22–3.82) or normal-weight grandparent (OR=2.1, 95% CI: 1.06–4.05).
Conclusion: Children living with overweight parent(s) or grandparent(s) were positively correlated with the risk for childhood overweight and obesity. Socioeconomic status did not affect the observed relationships in this population, whereas the role of genetic, dietary and activity patterns requires further exploration.
