Abstract

OBJECTIVES
Few studies have attempted to explain the association between socioeconomic status (SES) and obesity in Korea. Especially the studies on same race with different SES at same time are good for SES influence estimation. The present study highlights the influence of SES of parents on adolescent obesity. The subjects are the same race, but live in different areas, with different SES, Seoul and Yangpung in Korea, and Yanbian in China. METHODS: The cross-sectional study was conducted in Mar-Jun 1996. We carried out anthropometry, 24 hour-recall diet survey, self-reported questionnaire about sociodemographic characteristics and physical activity. For SES indicators, we used income and education of parents. RESULTS: The relationship between SES of parents, defined as educational status, and obesity in boys in Korea and China is direct, but not significant. The relationship is inverse and non-significant among Korean girls. However, for the Korean girls in severe obesity, the relationship is significant. For the Korean-Chinese girls, there is an inverse relationship between the education level and obesity but a direct relationship between the income level of parents and obesity. For the Korean adolescent, there are a direct association between the SES of parents and the nutrients factors such as energy, protein, and fat intake. The energy expenditure of adolescent has no relationship with SES of parents. CONCLUSION: Among boys, the higher the SES, the greater the risk of obese. Among girls in Korea and Korean-Chinese, on the other hand, the lower the educational status of parents, the greater the risk of obese.
