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.
