Background Vitamin D deficiency in pregnancy has important maternal and fetal implications, with increased risk of developing gestational diabetes, preeclampsia, preterm birth and small for gestational age birthweight. It is recommended that every pregnant woman should take 5 μg (200 IU) of vitamin D per day during pregnancy and lactation.

The claim that large proportions of North American and other populations are deficient in vitamin D is based on misinterpretation and misapplication of the Institute of Medicine reference values for nutrients — misunderstandings that can adversely affect patient care.

Associations between vitamin D and pregnancy outcomes have been inconsistent.We described the distribution of 25-hydroxyvitamin D3 [25(OH)D3], 3-epi-25(OH)D3, and 25(OH)D2 in early pregnancy and investigated associations with pre-eclampsia and small-for-gestational-age (SGA) birth, which are indicative of uteroplacental dysfunction.The SCOPE (Screening for Pregnancy Endpoints) Ireland prospective pregnancy cohort study included 1768 well-characterized low-risk, nulliparous women resident at 52°N...

In most large cities in the Northern hemisphere in the late 19th and early 20th centuries, rickets was an enormous public health problem, mainly because exposure to sunlight was limited, particularly for children.1 German physicians noticed that daily administration of a tablespoon of cod liver oil could reverse rickets, a finding that led to the discovery of vitamin D, its structure, and function. In the United States, most of the milk supply is now voluntarily fortified with vitamin D, whereas...

Importance Asthma and wheezing begin early in life, and prenatal vitamin D deficiency has been variably associated with these disorders in offspring. Objective To determine whether prenatal vitamin D (cholecalciferol) supplementation can prevent asthma or recurrent wheeze in early childhood. Design, Setting, and Participants The Vitamin D Antenatal Asthma Reduction Trial was a randomized, double-blind, placebo-controlled trial conducted in 3 centers across the United States. Enrollment began in ...

Background In recent years the role of vitamin D status in early life on the development of allergic disease has generated much interest. The aim of this study was to determine whether cord blood vitamin D concentrations were associated with risk of early childhood allergic disease.

Background The Institute of Medicine 2011 Report on Dietary Reference Intakes for Calcium and Vitamin D specified higher intakes for all age groups compared to the 1997 report, but also cautioned against spurious claims about an epidemic of vitamin D deficiency and against advocates of higher intake requirements. Over 40 years, we have noted marked improvement in vitamin D status but we are concerned about hypervitaminosis D.

Objective To assess the association between serum 25-hydroxyvitamin D (25OHD) levels and outcomes in preterm infants ( Study design Serum 25OHD was measured in mothers and their infants within 24 hours of birth, before the start of enteral vitamin D supplementation, and at discharge from the neonatal intensive care unit. We evaluated the associations between vitamin D status and various early preterm outcomes. Results Ninety-four preterm infants and their mothers were included; 92% of the infant...

Background Epidemiological studies have suggested an association between maternal vitamin D dietary intake during pregnancy and risk of asthma and allergy in the offspring. However, prospective clinical studies on vitamin D measured in cord blood and development of clinical end-points are sparse.

Introduction The Institute of Medicine (IOM) 2011 on dietary references intakes for calcium and vitamin D specified that a 25-hydroxyvitamin D (25OHD) level below 30 nmol/L indicated risk of deficiency and that a level above 125 nmol/L indicated risk of harm.

Iron deficiency is associated with atopy. Iron deficiency during pregnancy increases the risk of atopic diseases in children, while both allergic children and adults are more likely to have iron deficiency anemia. Immunologically, iron deficiency leads to activation of antigen-presenting cells, promotion of Th2 cells and enables antibody class switch in B cells. In addition, iron deficiency primes mast cells for degranulation, while an increase in their iron content inhibits their degranulation....
OBJECTIVES Vitamin D plays an important role in the release of the placenta and implantation, and low levels are a risk factor for pre-eclampsia. Studies have also shown that symptomatic treatment of vitamin D3 deficiency can effectively reduce the risk of pre-eclampsia. In this study, vitamin D3 supplementation was performed on the risk of pre-eclampsia to observe its effect. METHODS From January 2016 to December 2018, 450 women with maternal treatment and delivery in our hospital underwent an ...
