Abstract
Purpose
: This study aimed to assess the prevalence of obesity, hypertension, and hyperlipidemia in children from low-income families in Gunpo and to evaluate whether economic status affects the prevalence of obesity.
Methods
: Between October 2007 and March 2008, 341 children (167 girls and 174 boys; age, 6 to 13 years) were enrolled in this study. All these children came from families who earned minimum wages and who were supported by government. We measured height, weight, and blood pressure and performed laboratory examinations, including total cholesterol, high- density lipoprotein cholesterol, and triglycerides. Body mass index (BMI) was calculated using weight and height. We compared the prevalence of obesity, hypertension, and hyperlipidemia in children from low-income families with the prevalence of these maladies found in other studies.
Results
: Prevalence of obesity (BMI≥95th) was 7.1%. Prevalence of hypertension and hyperlipidemia was 8.2% and 16.7%, respectively. In the obese group, prevalence of hypertension and hyperlipidemia was 25.0% and 45.8%, respectively. Obesity and hyperlipidemia were slightly more frequent in our study than those found in other reports, and the prevalence of hypertension in the obese group was very high compared with statistics from the Korean National Health and Nutrition Examination Survey (25% vs. 19.5%) and those from other reports.
Conclusion
: Low-income status was associated with an increased incidence of obesity, hyperlipidemia, and hypertension. Hypertension showed an especially strong association with economic status, which seemed to correlate with genetic, environmental, and dietary effects.
Key Words: Low income, Hypertension, Obesity, Hyperlipidemia, Children
