Body fat distribution and cardiovascular disease risk factors in pre- and postmenopausal obese women with similar BMI

The aim of this study is to determine the body fat distribution and cardiovascular disease risk factors in pre- and postmenopausal obese women matched for weight, height and body mass index (BMI). Study group consisted of 405 premenopausal overweight/obese (BMI >27 kg/m(2), mean 37.83+/-6.91 kg/m(2)) and 405 postmenopausal overweight/obese (BMI >27 kg/m(2)), BMI-matched (mean 37.77+/-6.84 kg/m(2)) women. None of the women were on hormone replacement therapy. Insulin resistance was evaluated by "homeostasis model assessment" (HOMA) formula. Intraabdominal fat volume was calculated according to the following formula: IAF (L)=[(0.370 x abdominal sagittal diameter) -4.85]. Age, waist circumference, waist to hip ratio (WHR) and intraabdominal fat volume were significantly higher in postmenopausals compared with BMI-matched premenopausal women (p50 years) had significantly higher systolic blood pressure, waist circumference, WHR, glucose and uric acid concentrations compared with younger (less than or equal to50 years) postmenopausals. It is concluded that an increase in abdominal fat accumulation and unfavorable alterations in risk factors disturb postmenopausal obese women even if total body weight and BMI do not change during menopause transition. Ageing, particularly throughout the postmenopausal years, has important effects on the detrimental changes associated with menopause
