AbstractIntroductionVitamin 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 and methods360 obese women were randomised 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 si...

ConclusionsThe development of childhood atopy may be associated with maternal vitamin D deficiency in early pregnancy among a cohort of women at risk of vitamin D deficiency. Further research is required to explore the relationship between vitamin D and atopy, particularly among women with poor vitamin D status, and whether supplementation should be prioritised in early pregnancy to reduce childhood atopy.

AbstractVitamin D deficiency is observed worldwide and represents a health hazard for mothers, infants and elderly persons. We know that many young Japanese women experience vitamin D insufficiency; however, there is a lack of knowledge regarding the serum 25-hydroxyvitamin D [25(OH)D] profile of pregnant Japanese women and of the association between maternal 25(OH)D level and maternal bone mass during pregnancy and lactation. In this longitudinal study, 160 pregnant Japanese women were enrolled; of them, 68 have been followed-up from the first trimester through at least 1  year of breast-feeding. We estimated serum 2...

AbstractVitamin D deficiency has been associated with adverse pregnancy and birth outcomes such as increased risk for preterm birth and preeclampsia. This state of the science review analyzed recently published meta ‐analyses and relevant studies that have evaluated the association between vitamin D deficiency and preeclampsia or preterm birth. The results suggest that a positive association between vitamin D deficiency and preterm birth exists. However, the findings of the relationship between vitamin D defi ciency and preeclampsia were inconclusive, possibly because of the need for supplementation to occur prior to pla...

Authors: Anusha K, Hettiaratchi U, Gunasekera D, Prathapan S, Liyanage G Abstract Epidemiologic studies from South Asian countries have reported vitamin D deficiency among all age groups. However, there is very little information on vitamin D levels, especially in the vulnerable populations (pregnant/breast feeding mother and infants) in Sri Lanka. More data on vitamin D status of such populations will be important for policy decisions to be made at a national level. Similarly, it will be valuable for healthcare programs in other countries (e.g., United States, Australia, Europe, and Canada) as Sri Lankans are a fa...

Authors: Nema J, Sundrani D, Joshi S Abstract Objective: Vitamin D plays a key role during pregnancy and is involved in implantation and maintenance of pregnancy. Its deficiency is associated with pregnancy complications like preeclampsia, characterized by abnormal angiogenesis.Method: The current article summarises studies examining the role of vitamin D in pregnancy, with special emphasis on preeclampsia.Results and conclusion: An imbalance in pro- and anti-angiogenic factors is reported in women with preeclampsia. Cell culture studies have demonstrated that vitamin D can influence the process of angiogenesis. Ho...

We report two case studies of full-term newborns who presented long-bone fractures associated with severe vitamin D deficiency transmitted to them by their mothers, even though maternal supplementation had been implemented according to the existing recommendations. These observations encourage the investigation of neonatal vitamin D deficiency in the presence of long-bone fractures in the absence of traumatic birth and the necessity of reenforcing the means of prevention and the selection of risk groups in order to adjust vitamin D supplementation during pregnancy individually.

In conclusion, vitamin D status among pregnant Mongolians is severely depressed throughout the year and should be addressed through fortification and supplementation, while in the U.S.), deficiency is associated with specific characteristics targetable through supplementation.
