The Relationship between Waist Circumference/Height Ratio and Risk Factors of Cardiovascular Disease in Obese Females

ABSTRACT

BACKGROUND: In this study we estimated the prevalence of cardiovascular (CV) risk factors according to waist-to- height ratio (W/Ht ratio) in adult obese women to ensure the importance of abdominal obesity and determined the usefulness of W/Ht ratio as a index of abdominal obesity in adult obese women. METHODS: The study subjects were 190 adult obese women who visited an obesity clinic from August, 2001 to January, 2003. They were divided into 4 groups Group 1; BMI or =0.6, Group 3; BMI> or =30, W/Ht or =30, W/Ht> or =0.6. In each group, we compared the prevalence and odds ratio for CV risk factors. RESULTS: In obese group, the prevalence of high blood glucose (P<0.01), hypertriglyceridemia (P<0.01) were significantly higher in group 2 than group 1. In high obese group, the prevalence of systolic hypertension (P<0.01), high blood glucose (P<0.01), hypercholesterolemia (P<0.01), hypertriglyceridemia (P<0.05), and high LDL-cholesterol were significantly higher in group 4 than group 3. When odds ratio for each group with reference to group 1 were compared after adjusting for age, high blood glucose (4.48), and hypertriglyceridemia (6.10) in group 2, and systolic hypertension (2.69), high blood glucose (3.02), and hypertriglyceridemia (4.00) in group 4 were significantly higher. CONCLUSION: The prevalence of CV risk factors were likely to be increased in higher W/Ht group independently to BMI. W/Ht ratio can be a simple, useful index for abdominal obesity and its related risk factors not only in adult males but also in adult obese women.
