BACKGROUND: Sex hormones are strongly linked to the occurrence and development of diabetes, and influence glycated hemoglobin (HbA1c) levels in diabetic population; but, the relationship between sex hormones and HbA1c in non-diabetic population remains unknown. This study aimed to explore the extent of influence of sex hormones on HbA1c levels in non-diabetic population.
METHODS: A total of 1409 non-diabetic subjects, including 601 men and 808 postmenopausal women were recruited from Shanghai community. HbA1c was detected using high performance liquid chromatography, and hemoglobin level was determined by sodium lauryl sulfate colorimetry. Serum estradiol (E2), total testosterone (TT), and sex hormone binding globulin (SHBG) were measured by chemiluminescent microparticle immunoassays.
RESULTS: The level of HbA1c was 5.6 (5.4-5.9) % in all subjects, with 5.6 (5.4-5.8) % in men and 5.7 (5.5-5.9) % in postmenopausal women. After adjusting for age, body mass index (BMI), and hemoglobin, E2 was positively correlated with HbA1c in men (r = 0.122, P = .003), and SHBG was inversely correlated with HbA1c (r = - 0.125, P < .001) in women. Other hormones were not correlated with HbA1c (all P > .05). Multivariate linear regression analysis showed that, except for traditional factors, such as age, hemoglobin, and BMI, E2 was another determinant of HbA1c (standardized β = 0.137, P = .003) in men; besides, in women, SHBG was another determinant of HbA1c (standardized β = - 0.178, P < .001), except for age and systolic blood pressure.
CONCLUSION: After controlling for confounding factors, two sex hormones, as E2 and SHBG could influence HbA1c levels in non-diabetic population.
