BACKGROUND: Vitamin D status, as measured by serum 25-hydroxyvitamin D (25(OH)D), has been shown in some studies to be inversely associated with gestational diabetes risk. Recently, it has been suggested that maternal smoking status may modify this relationship. We explored the association between 25(OH)D concentration and gestational diabetes and determined if there was an interaction between smoking and 25(OH)D. METHODS: A nested case-control study was conducted in Halifax, Nova Scotia and Quebec City, Quebec...

Based on the Hyperglycemia and Adverse Pregnancy Outcome study, new universal screening recommendations and cut-offs for gestational diabetes mellitus (GDM) have been proposed. In addition to the immediate perinatal risk, GDM carries an increased risk of metabolic disease in the mother and child. Maternal obesity has even been shown to be associated with increased all-cause mortality in offspring. In addition to known risk factors, excessive gestational weight gain, increased fat consumption, a low vitamin D level, psychological stress and negative mood are risk factors for GDM...
