Abstract
  • Increasing trends of overweight have been found in children with intellectual disabilities (ID) as well as in typically developing children worldwide. Most evidence has shown that overweight is more prevalent in children with ID than in typically developing children. Identifying overweight risk factors is critical for understanding the development of overweight during childhood. Therefore, the purpose of this study was to identify relationships between children's and parental risk factors, dietary patterns and weight status in children with ID aged 7 to 11 years driven by the modified Vulnerable Populations Model. From December 2009 to January 2010, a convenience sample of 88 parents of children with ID aged 7 to 11 years was recruited from four special schools in South Korea. Parents of children were asked to complete a survey and 3-day food records. The collected data were analyzed using SAS (version 9.2). Exploratory factor analysis was used to identify children's dietary patterns. Correlation coefficients were used to examine the relationships between children's and parental risk factors and dietary pattern scores. The relationships between children's and parental risk factors and children's weight status were assessed using Chi-square with Fisher's exact test and ANOVA. To test the hypothesis that multiple risk factors were associated with weight status in children, logistic regression analysis was performed. Two thirds of children were normal weight and 19% of children were overweight or obese. More than half of the children had moderate intellectual disabilities; and 36% of children had severe intellectual disabilities. This study found that both severity of disability and parental education were significant factors of overweight in children. Mild or moderate ID was associated with being overweight in children. Lower parental education was associated with overweight in the children. Two dietary patterns, Korean dietary pattern and Westernized dietary pattern, were identified: low scores on the Korean dietary pattern were associated with increased risk of overweight in children. Overall, these findings provide a basis for future studies of the risk factors and causes of overweight in children with ID aged 7 to 11 years, as well as for effective overweight prevention programs.
