ABSTRACT
INTRODUCTION:
Vitamin D deficiency is common in pregnancy, especially in obese women. Lifestyle intervention could potentially result in higher levels of vitamin D. We therefore aimed to study the effect of lifestyle intervention during pregnancy on serum levels of 25-hydroxyvitamin D (25(OH)D). MATERIAL ANDMETHODS:
A total of 360 obese women were randomized before gestational age 14 weeks to lifestyle intervention (diet and exercise) or routine clinical follow up (controls). Clinical outcomes and levels of 25(OH)D were determined three times At gestational age 12-15 weeks (baseline), gestational age 28-30 weeks and 6 months postpartum.RESULTS:
A total of 304 (84%) women completed the intervention study and 238 (66%) attended postpartum follow up. Vitamin D levels were similar in the two groups at baseline. At gestational age 28-30 weeks and 6 months postpartum, 25(OH)D levels were significantly higher in the intervention group than in controls (75.6 vs 66.8 nmol/L, P = 0.009) and (54.8 vs 43.1 nmol/L, P = 0.013), respectively. Concurrently, vitamin D deficiency (25-hydroxyvitamin D <50 nmol/L) was less frequent in the intervention group than in controls 15 vs 25% (P = 0.038) at gestational age 28-30 and 45 vs 63% (P = 0.011) 6 months postpartum, respectively.CONCLUSIONS:
Lifestyle intervention during pregnancy was associated with significantly increased vitamin D levels in late pregnancy and postpartum compared with controls.Palabras clave
