Abstract

To determine the obesity indices (BMI, Waist, WHR) as the factors on risk of obesity related
chronic disease in Korea.
We have examined 14,018 adults (6964 men, 7054 women) in Ajou university hospital (suwon,
Korea) who took the annual examination from June, 1994 through Jan, 1999. We measured
height, weight, waist and hip circumference. All blood samples were taken after 12 hours fast,
at the same time point as anthropometric indices measurements. Electrocardiography and
Abdominal sonography were taken at the same time. The obesity related chronic disease were
estimated in conjunction with obesity indices. We defined the sum of obesity related disease as
morbidity index.
In men, the prevalence of obese (more than 30 kg/m2) and overweight (25∼29.9 kg/m2) was
1.4%, 29.4%, respectively. In women, the prevalence of obese (more than 30 kg/m2) and
overweight (25∼29.9 kg/m2). The prevalence of obesity related disease increased with age was
1.9%, 19.4%, respectively. This results show that the prevalence of obesity in Korea is relatively
low. The percentile by BMI, Waist circumference, waist to hip ratio for men and women. The
80 th percentile for the BMI is 25 kg/m2 in men and women. The 80 th percentile for the waist
circumference was 94 cm in men. The 80 th percentile for the waist circumference was 80 cm in
women. The 95 th percentile for the BMI was 28 kg/m2 in men and women. This value is smaller
than that of Caucasians. The 80 th percentile for the waist to hip ratio of men and women was
0.90, 0.83 respectively. The prevalence of obesity related disease increased with BMI, reaching
a peak at 25 kg/m2 in men and women. And the prevalence of obesity related disease in men and
women increased with waist circumference, reaching a peak at 90 cm, 80 cm, respectively. In
waist to hip ratio, at the 0.8 in women, 0.9 in men, the prevalence of obesity related disease
especially increased .
The obesity related chronic disease increased with BMI at 23 kg/m2, reaching a peak at 25∼
28 kg/m2 in men and women. And the morbidity index increased with waist circumference at 94
cm in men, 80 cm in women. The morbidity index increased with waist to hip ratio 0.9 in men,
0.83 in women.
