Metabolic syndrome (MetS) is a constellation of metabolic risk factors for cardiovascular disease in one individual. The more risk categories identified, the higher the potential risk. The diagnosis of MetS is based on the presence of three or more risk categories found in the same person [1]. Assessment and management of MetS become an important cornerstone in primary prevention of cardiovascular disease.

Two recent publications from SWAN (Study of Women’s Health Across the Nation) investigated the prevalence of MetS in the menopausal transition. In the first study [2], 949 healthy, non-users of hormone replacement therapy (HRT) were recruited when they were premenopausal or early perimenopausal and were followed throughout their menopausal transition. By the final menstrual period, 13.7% of the women had new-onset MetS. The main components of the MetS which showed an adverse change during follow-up were: systolic blood pressure, triglycerides and waist circumference. An increase in bioavailable testosterone or a decrease in sex hormone binding globulin levels increased the odds of developing MetS. The second study [3] looked into possible correlations between MetS and the serum levels of various sex hormones. The cohort included 1862 women, aged 42–52 years, who were followed for 5 years. There were 257 new cases of MetS diagnosed during the menopausal transition. Estradiol (E2) and total testosterone (T) levels declined by 12% and 3% per year, respectively, leading to a 10% per year increase in the T/E2 ratio and creating a state of relative androgen excess. Incident MetS correlated with a higher baseline T/E2 molar ratio and its rate of change over time during follow-up. As testosterone progressively dominates the hormonal milieu during the menopausal transition, the prevalence of MetS increases, independent of aging and other important covariates.
