title: Waist related anthropometric measures - simple and useful predictors of coronary artery disease in women.
abstract: OBJECTIVE
  To compare the waist related anthropometric measures like waist circumference, waist-to-height ratio (WHtR), waist - hip ratio (WHR) and body mass index (BMI) as predictors of coronary artery disease (CAD) in women.
  
  
  METHODS
  The study included 88 women aged 40-80 years. Waist circumference, hip circumference, height, weight, age, and other covariates were collected by questionnaire. The primary endpoint was incident coronary heart disease that was reported by physician. The data was analyzed statistically using χ(2)-test for quantitative data and student t-test. The significance of the results as determined in 95.0% confidence interval.
  
  
  RESULTS
  The mean age was 59.07 ± 11.53 in the study group and 54.36 ± 10.84 in the control group. The waist circumference in the study group was higher (95.443 ± 11.187) than the control group (74.886 ± 6.672) (p < 0.001). The mean waist to hip ratio (WHR) was 0.96 ± 0.08 in the study group and 0.78 ± 0.06 in the control group (p < 0.001). The mean waist to height ratio (WHtR) was 0.62 ± 0.07 in the study group and 0.48 ± 0.04 in the control group (p < 0.001). Waist derived measures were superior to BMI in predicting CAD. The unadjusted AUC (95% Confidence Interval) was 0.008 (0.006-0.095) for WHtR, 0.001 (0.00 0.002) for waist - hip ratio, and 1 (0.323-1.766) for body mass index.
  
  
  CONCLUSIONS
  Waist related anthropometric measures are important predictors as CAD risk factors among middle-aged and older women, as compared to BMI.
