摘要：The aim of this study was to assess the relation between dietary intake of vitamin D and insulin resistance in obese and nonobese women. This cross-sectional study included 93 women, aged between 20 and 50 years, who were subdivided into two groups: the obese group (n = 46) and the agematched control group (n = 47). Vitamin D and calcium intake was monitored using 3-day food records and Dietpro software version 5.1. Measurements of serum glucose and serum insulin were based on an enzymatic colorimetric method and a chemiluminescence assay, respectively. Insulin resistance was assessed by means of homeostasis model assessment of insulin resistance (HOMA-IR). The median values of vitamin D content in the diet were found to be lower than those recommended, although there was a significant difference between groups (p < 0.001). The mean values of calcium intake were found to be above the recommendations, although there was no significant difference between the groups (p > 0.05). The values of serum glucose, serum insulin, and HOMA-IR were higher in obese women than in the control group. The correlation analysis indicated that the association between the dietary intake of vitamin D and insulin resistance was not significant. The results of this study indicate that dietary vitamin D does not influence parameters of glycemic control in obese women.
