Comparison of anthropometric parameters as predictors of serum lipids in premenopausal women.

摘要

No single anthropometric parameter has yet been generally accepted as being superior to others in assessing the metabolic risk associated with abdominal obesity. To compare waist circumference (WC) with waist-to-hip ratio (WHR) and waist-to-height ratio (WHtR), regarding their association with serum lipids, we studied 166 women aged 20 to 48 yr; 53 were obese body mass index (BMI) 30-39.9 Kg/m2, 50 were overweight (BMI 25-29.9 Kg/m2) and 63 normal weight (BMI 18.5-24.9 Kg/m2). Height, body weight, waist and hip circumferences, total serum cholesterol (Ch), low (LDL) and high density lipoprotein (HDL)-Ch and triglyceride (TG) concentrations were measured. The correlation coefficients between the concentration of serum lipid fractions and each anthropometric parameter did not differ significantly for any lipid variable when WC, WHR and WHtR were compared in the 166 women. The same applied for the obese and the overweight group, whereas in normal weight women there was significant association only between WC and LDL-Ch and between WHR and Ch/HDL-Ch ratio. Stepwise regression analysis showed that the proportion of variance in serum lipids did not change significantly when WHR or WHR+WHtR were added to WC into the regression model (18, 18 and 18 for Ch; 13, 18 and 18 for HDL-Ch; 18, 18 and 12 for LDL-Ch; 35, 35 and 37 for TG, respectively). These results indicate that WC is the main parameter associated with serum lipid levels and that the ratios studied do not provide additional substantial information in women who need weight management.
