title: Body fat distribution and cardiovascular disease risk factors in pre- and postmenopausal obese women with similar BMI.
abstract: 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/m2, mean 37.83 +/- 6.91 kg/m2) and 405 postmenopausal overweight/obese (BMI > 27 kg/m2), BMI-matched (mean 37.77 +/- 6.84 kg/m2) 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 (p < 0.001). Systolic and diastolic blood pressure, glucose, uric acid, cholesterol and triglyceride were significantly higher (p < 0.001) and HDL-cholesterol was significantly lower (p < 0.05) in postmenopausals. No significant differences were observed with respect to insulin and HOMA. When age-matched pre- and postmenopausal women were compared, only total cholesterol was significantly higher in the postmenopausal group. However, older postmenopausal women (> 50 years) had significantly higher systolic blood pressure, waist circumference, WHR, glucose and uric acid concentrations compared with younger (< or = 50 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.
