    Vitamin D deficiency and visceral adipose tissue in early pregnant women. Cisneiros Rosangela,Segatto Juliana,Paixão Eloíse,Bacellar Ítalo,Lima Marcelo,Pacheco Álvaro,Alves João Guilherme,Bandeira Francisco BMC pregnancy and childbirth BACKGROUND:We aimed to assess the correlation between vitamin D serum level and visceral fat tissue during early pregnancy. METHODS:This cross-sectional study was performed in Pernambuco, Brazil. 190 low risk pregnant women (8-16 gestational weeks) were eligible. Visceral adipose tissue was measured by ultrasonography following the technique described by Armellini. The 25(OH) D in serum was determined through chemiluminescence. The Spearman correlation test was applied to evaluate the correlation between vitamin D serum level and VAT, considering p < 0.05 to be significant. RESULTS:Vitamin D insufficiency was present in 129 (67.8 %) of subjects. Pregnant women with or without vitamin D deficiency did not differ in age, gestational age, nutritional status and visceral adipose tissue. No correlation between visceral adipose tissue and 25(OH) D was observed: - 0.057 (p = 0.435). CONCLUSIONS:Maternal visceral adipose tissue and vitamin D serum level are not correlated during pregnancy. 10.1186/s12884-021-03888-1
    The Relationship between Vitamin D Status and Visceral Fat Accumulation in Males with Type 2 Diabetes. Liu Bowei,Fan Dongmei,Yin Fuzai Journal of nutritional science and vitaminology 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 cm. 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. 10.3177/jnsv.66.396
