Background: Abdominal obesity is an important factor
of metabolic syndrome and it is known as an independent
risk factor of cardiovascular disease. The prevalence of
obese population in Korea is lower than that of the
Western countries, but the prevalence of obesity related
chronic diseases in Korea is as high as that in the western
countries. The aim of this study is to recommend a
desirable diet pattern to maintain good health by
examining the association of waist circumference and
carbohydrate intake in Korea.
Methods: From June 2003 to April 2006, 2066
subjects (men 976, women 1090) who aged 40 to 64
years and underwent a medical checkup in the health
promotion center at a university hospital in Seoul were
selected. Anthropometric parameters were assessed,
including waist circumference and dietary data which was
obtained by 24-hour recall method. The nutrient data were
analyzed by CAN-pro 2.0, nutritional analysis program.
To evaluate the association between different variables
and waist circumference, we conducted univariate and
multiple linear regression analysis.
Results: In both men and women, variables such as
total calorie intake, carbohydrate intake, protein intake, fat
intake, and BMI had positive association with waist
circumference according to univariate linear regression
model. After adjusting total calorie intake, there was no
association between nutrient intake and waist
circumference in men. However, there was a positive
association between carbohydrate intake (β = 0.027, P <
0.001) and waist circumference in women.
Conclusion: In 40~64 aged women, carbohydrate intake
has a positive association with waist circumference. It is
necessary to study this association in conjunction with
other life style factors among various populations.
