RESUMO
The aim of this study is to evaluate the association between vitamin D status and glycemic profile in postmenopausal women with type 2 diabetes. A cross-sectional study was carried out with 70 (59.47⯱â¯6.47 years; 1.56⯱â¯0.05â¯m; 73.56⯱â¯13.01â¯kg; 30.30⯱â¯5.00 BMI kg/m2) postmenopausal women with type 2 diabetes (T2D). The blood samples were collected after fasting for 12â¯h and the main outcome parameters were serum follicle-stimulating hormone (FSH), estradiol; 25-OH vitamin D; insulin; C-Reactive Protein; cholesterol total (CT), triglycerides (TG), high density lipoprotein (HDL-cholesterol), glucose; calcium, HDL-cholesterol. The average serum 25(OH)D level in this study was 28.45⯱â¯8.26â¯ng/mL. The prevalence of hypovitaminosis D was 60%. Table 1 displays mean and standard deviation values for participants' characteristics. The postmenopause status of the women studied was confirmed by FSH and estradiol measurement. All the clinical and anthropometric characteristics did not show difference (pâ¯>â¯0.05) between the groups (Table 2). Triglycerides level was highest (pâ¯<â¯0.0391) in the hypovitaminosis D group. The other serum markers did not show statistical differences (pâ¯>â¯0.05) between the groups. In conclusion, our results suggest that only TG level shows a negative correlation with vitamin D status in postmenopausal women with type 2 diabetes.
