Note: There are two groups of maternal Vitamin D levels
< 28 ng and > 39 ng
Suspect those mothers with lower vitamin D levels had concealing clothing (Muslem)

- Burka clothing reduces vitamin D levels, which causes pregnancy problems – Oct 2015
- Pregnant Arab women 25 X more likely to have low vitamin D if indoors a lot – April 2018
- Malay women 14 X more likely to be Vitamin D deficient than Chinese in Malay – July 2017
- Malay women wear concealing clothing, the Chinese do not

CONTEXT: The neonatal skeletal outcomes due to maternal Vitamin D deficiency.
The aim of this study is to assess the serum 25 hydroxy Vitamin D (25[OH]D) status in pregnant women and correlate with cord blood 25(OH)D levels, femur length at 34 weeks gestation, and neonatal anthropometry (birth weight, birth length, and head circumference).
SETTINGS AND DESIGN: This was prospective cohort study.
SUBJECTS AND METHODS:
This study was carried out in 250 healthy primigravida between 18 and 40 years of age in the third trimester of gestation attending the Obstetrics and Gynaecology Department of Gauhati Medical College, Guwahati from December 2012 to December 2015. Dietary assessment of calcium and Vitamin D intake, sunlight exposure among the pregnant mothers and fetal femur length measurements were done. The neonates were followed up at birth for biometric assessment and the estimation of cord 25(OH)D.
STATISTICAL ANALYSIS USED:
Chi-square test and Pearson correlation were carried out to see the association and correlation between different variables. Statistical significance was set at the 0.05 level.
We found low Vitamin D levels (60%) in the majority of pregnant mothers and newborns (62.4%). The mean Vitamin D levels were 17.51 ± 2.24 ng/ml and 14.51 ± 1.8 ng/ml among the low Vitamin D maternal subjects and their new born, respectively. There was a significant association of maternal Vitamin D levels with sun exposure, dietary intake of Vitamin D, serum calcium, serum alkaline phosphatase levels, and serum parathyroid hormone in subjects with low Vitamin D. Fetal femur length and birth length were significantly shorter in mothers with low Vitamin D (P < 0.01).
CONCLUSIONS: Maternal hypovitaminosis D was associated with adverse skeletal outcome in neonates.
