Introduction and objectives: Vitamin D deficiency has been associated with altered glycemic metabolism and metabolic syndrome. New data suggest that it might have a role in prevention of gestational diabetes mellitus and preeclampsia. The present study was designed to analyze the relationship between vitamin D with parathormone levels, bone turn over markers and metabolic control.

Methodology: The sample consisted of 44 pregnant women with gestational diabetes mellitus, ages 15-45, who attended to endocrinology external consultation. The variables analyzed were 25-hydroxivitan D, parathormone, fructosamine, total calcium, ionic calcium, calcium corrected by albumin and phosphorus, also, the relationship with body mass index, season of the year and age.

Results: 25-hydroxivitamin D levels were analyzed regarding the season of the year; the average value was 37 ng/ml in summer, 26 ng/ml in autumn, 24 ng/ml in spring and 17 ng/ml in winter. There was an inverse relationship between vitamin D and parathormone (p<0.014). The analysis regarding vitamin D and BMI revealed the following values, 32.27 ng/ml for BMI <30 and 23.63 ng/ml for BMI >30 (p<0.027). There was an inverse relationship between Vitamin D and fructosamine (p 0.479).

Conclusions: The prevalence of Vitamin D deficiency during pregnancy must be taken into account because of the implications in multiple aspects of maternal, fetal and postnatal health, especially when it is associated with other risk factors as overweight, obesity and gestational diabetes mellitus.

Keywords : Vitamin D Deficiency Pregnancy; Gestational diabetes mellitus Bone turnover.
