Research summary
Concerns have been expressed globally about vitamin D deficiency among pregnant women. There is no national data on the prevalence of vitamin D deficiency among pregnant women in Scotland. Vitamin D levels are not routinely
measured during pregnancy so the extent of this problem among local women is not known.
Primary Research Objective:
The aim of the study is to assess vitamin D status in a group of pregnant women living in Ayrshire and the effect of
vitamin D supplementation on their serum 25 hydroxyvitamin D (25 OHD) levels. The primary outcome measure will be serum 25 OHD levels at 12 and 34 weeks gestation.
Secondary Research Objectives:
The objectives of the study are to:
• Describe the characteristics of pregnant women with regard to age, social position (determined by Scottish Index of
Multiple Deprivation (SIMD) category), parity, smoking status and BMI.
• Measure the bone profile and vitamin D levels of two groups of pregnant women at two time points (one group in
winter and the other in summer) to assess seasonal variation in vitamin D.
• Assess the efficacy of vitamin D supplementation in this group.REC name
