The association between serum testosterone levels and metabolic syndrome among women
Abstract
Abstract Background This study aimed to investigate the relationship between total serum testosterone level (TT) and metabolic syndrome (MetS) among adult female population. Subgroup analysis further stratified the population by menopausal status to address the potential hormonal difference in postmenopausal women. Methods A total of 1966 participants from the National Health and Nutrition Examination Survey (NHANES) 2011–2012 cycle was included for analysis in this study. MetS was defined based on the National Cholesterol Education Program Adult Treatment Panel III guidelines. Serum TT was collected during the physical examination of the NHANES program and divided into quartiles (Q) in this analysis. Menopausal status was determined based on NHANES Reproductive Health Questionnaire. Logistic regression models were applied for analysis. Results The odds of MetS in Q2: 12.99–19.38 ng/mL (OR = 0.641, 95%CI 0.493–0.835, P < 0.01), Q3: 19.39–28.38 ng/mL (OR = 0.476, 95%CI 0.362–0.626, P < 0.001), and Q4: ≥28.40 ng/mL (OR = 0.390, 95%CI 0.294–0.517, P < 0.001) were statistically lower compared to the reference Q1: <12.99 ng/mL. For the postmenopausal group, a significantly lower odds of MetS was observed in the Q2 (OR = 0.689, 95%CI 0.486–0.977, P < 0.05) and Q4 (OR = 0.606, 95%CI 0.399–0.922, P < 0.05), while the odds of Q3 (OR = 0.439, 95%CI 0.248–0.779, P < 0.01) and Q4 (OR = 0.464, 95%CI 0.261–0.825, P < 0.01) were significantly lower than the reference Q1 in the premenopausal group. Conclusions Elevated TT levels are associated with incremental reductions in the odds of metabolic syndrome among adult females. Although, serum testosterone level is associated with the occurrence of metabolic syndrome in both the postmenopausal and the premenopausal group, the patterns of the relationship are different.
