Abstract
Diabetes mellitus (DM) is a growing health issue that has been reaching epidemic proportions in the recent years. Low intake of some nutrients like vitamin D may increase the risk of gestational diabetes mellitus (GDM). This study was to investigate the association between the dietary intake of Vitamin D and GDM among women in the Eastern Region of Saudi Arabia. A case-control study was conducted in a sample of 121 women, among those 72 were with GDM and 49 were controls. Vitamin D was estimated using food frequency questionnaire. Also, the 24-h’s dietary recall was carried out for 3 days to determine the nutrient intake as well as biochemical analysis for blood glucose level. In this study, GDM subjects were consuming significantly more eggs (
P
= .040). Vitamin D and vitamin C intakes in GDM and control pregnant women were lower than recommended dietary allowances (RDA). It was also found that low-fat milk, full-fat milk, fortified yogurt, and fortified orange juice were significantly associated with GDM (
P
< 0.05). Saudi women with GDM need a well-organized dietary counseling before, during pregnancy, and after delivery especially for vitamin D sources.
