Background: Rates of cardiovascular (CV) disease mortality is usually higher in men but this equalizes with that of women following menopause.

Objectives: This was to determine the contribution of abdominal obesity and estradiol to cardiovascular risk in postmenopausal women (PMW) as well as estimate their CV risk profile.

Methods: 271 consenting PMW were recruited consecutively into this cross-sectional hospital-based study. Data relating to their socio-demography, blood pressure and anthropometry was obtained and laboratory analysis of lipid profile and serum estradiol was done. Cardiovascular risk of participants was estimated using standardized calculators.

Results: Mean age of participants was 57.8±5.5 years. Significant correlation existed between each of triglyceride (Positive), High Density Lipoprotein (negative) and Waist-Hip-Ratio (WHR) (p=0.001 and 0.000 respectively). Hypertension and dyslipidaemia were significantly associated with WHR (p=0.01 and 0.031 respectively). Significant negative correlation existed between CV risk profile and serum estradiol (rs = -0.140, p = 0.028). Ten-unit increase in WHR was associated with two-fold risk of hypertension (OR> 1.73, C.I.= 1.13-2.66). A unit change in age was associated with 0.61 increase in TC.

Conclusion: Abdominal obesity and serum estradiol significantly influence cardio-metabolic risk. Newer risk calculator which incorporates factors peculiar to women such as serum E2 is hereby recommended.

Keywords: Cardiovascular risk; postmenopausal women; abdominal obesity.
