Vitamin D Postpartum Concentrations: Relationship with Nutritional Condition and Morbidities during Pregnancy.

Vitamin D Postpartum Concentrations: Relationship with Nutritional Condition and Morbidities during Pregnancy. J Pregnancy. 2018;2018:1070528 Authors: Martins MEP, Esmeraldo CUP, Sabiá JPD, Carvalho JHL, Suano-Souza FI, Sarni ROS Abstract Objective: To evaluate postpartum vitamin D deficiency/insufficiency and to relate it to pregestational BMI, gestational weight gain, and sociodemographic variables. Methods: This is a cross-sectional study with 225 full-term pregnant women. Data collected are as follows: maternal health, socioeconomic status, pregestational body mass index (BMI), and gestational weight gain. Laboratory evaluation included vitamin D [25(OH)D], calcium, phosphorus, magnesium, and alkaline phosphatase. Results: The mean age of women was 25.6±6.6 years. Dark skin color, low education, and work in the urban region were predominant. Regular sun exposure, photoprotection, and vitamin D supplementation were reported by 144 (64.0%), 44 (19.6%), and 5 (2.2%) women, respectively. The mean plasma concentrations of 25(OH)D were 26.0±6.8 ng/mL. Levels compatible with deficiency (

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 ‚Äźanalyses 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.

We studied a nested cohort from a randomized controlled trial to investigate the association between BV and vitamin D concentration in pregnancy. Study Design Subjects with randomly assigned 400 versus 4,400 IU of daily cholecalciferol (vitamin D3) had vaginal swabs collected for Gram staining and Nugent score calculation, as well as plasma 25-hydroxyvitamin D (25(OH)D) measurement at three pregnancy time points. Results Fifty-two (21.2%) of ...
