Metabolic profile and sex hormone binding globulin (SHBG) in different reproductive phases of Czech women and their relations to weight, body composition and fat distribution.
In our study, 213 healthy Czech women aged 20 to 65 years were examined and divided into fully reproductive, premenopausal, menopausal and postmenopausal groups. In all subjects body composition was determined by classical anthropometry and metabolic profile was assessed. A total of 146 subjects completed 3-year longitudinal study. Total and LDL cholesterol increased and ratio HDL/total cholesterol decreased with age (p<0.001), most significantly in menopause. Triacylglycerols increased only up to menopause. HDL had a very slight trend to decrease in menopause and postmenopause. Fasting blood glucose level increased progressively (p<0.001), in postmenopause frequently exceeded normal range. Higher BMI, total fat mass and central fat indices were associated with higher total and LDL cholesterol, triacylglycerols, C-peptide, insulin and fasting blood glucose level (p<0.001; fasting blood glucose level to waist-to-hip ratio: p<0.01) and lower HDL cholesterol (p<0.001). Higher C-peptide and insulin were associated with lower HDL cholesterol and higher triacylglycerols (p<0.001). Fasting glucose correlated with LDL cholesterol (p<0.01). Higher SHBG was associated with higher HDL and lower LDL cholesterol (p<0.001). Hormone replacement treatment was related to lower fasting blood glucose level in postmenopausal women (p<0.01). Oral contraception is suggestive of a positive influence on lipid spectrum by increasing the ratio HDL/total cholesterol. Markers of lipid and carbohydrate metabolism are not only age-related, but they are also related to BMI, total fat mass and central fat indices. Therefore, preventive programs should be focused above all on menopausal women.
