The Relationship between Vitamin D Status and Visceral Fat Accumulation in Males with Type 2 Diabetes.

Vitamin D deficiency may play an important role in obesity. The aim of the study was to explore the relationship between vitamin D status and visceral fat accumulation in males with type 2 diabetes. A cross-sectional study was conducted on 128 adult males with type 2 diabetes in Qinhuangdao. The nutritional status of vitamin D was assessed by circulating levels of 25(OH)D, vitamin D deficiency <30 nmol/L, vitamin D insufficiency 30-50 nmol/L and vitamin D sufficiency >50 nmol/L. Accumulation of visceral fat was defined as visceral fat area ≥100 cm2. The prevalence of visceral fat accumulation was 35.9%. The prevalence of visceral fat accumulation was 14.6%, 45.1% and 50.0% in type 2 diabetes with vitamin D sufficiency, vitamin D insufficiency and vitamin D deficiency, respectively. In multiple logistic regression analysis, subjects with vitamin D insufficiency [OR=4.255, p=0.012] and vitamin D deficiency [OR=6.122, p=0.022] were more likely to have visceral fat accumulation compared with subjects with vitamin D sufficiency. Visceral fat accumulation linked to the cluster of cardiometabolic risk factor in males with type 2 diabetes. There was a significant correlation between vitamin D status and visceral fat accumulation in males with type 2 diabetes.
