AimMethodologyResultsConclusionVitamin D is involved in several processes related to the development of neuronal and non-neuronal cells. There is a possible link between maternal vitamin D status in pregnancy and delayed neurocognitive development in the offspring. The aim of the study was to explore the association of maternal and cord blood vitamin D levels with infants’ neurodevelopment at 6 and 9 months of age.A cohort study was conducted in western Rajasthan, India. Maternal and cord blood samples were collected at the time of delivery. Serum 25(OH)-vitamin D levels were measured in both. Infant neurodevelopment was assessed at 6 and 9 months of age in six domains namely cognitive, receptive language, expressive language, fine motor, gross motor and social-emotional using the Bayley Scale of Infant Development- III (BSID-III).A total of 175 mother–child pairs were enrolled. Among the mothers taking part in this study, 7.3% had deficient and 59.09% had insufficient levels of serum 25(OH) vitamin D during the third trimester of their pregnancy. Maternal and cord blood serum 25-OH vitamin D levels were 18.86 ± 8.53 ng/mL and 17.39 ± 8.87 ng/mL, respectively, and there was a significant correlation (r = 0.9778, p = 0.000) between levels of vitamin D. Based on the repeated measures ANOVA, post hoc Tukey’s HSD test, maternal vitamin D levels had a significant relationship (p = 0.047) to the cognitive development of infants at 6 months of age. Furthermore, cord serum vitamin D levels showed a significant association (p = 0.023 and p = 0.010) with the social-emotional development of the infant at the age of 6 and 9 months.Maternal and cord serum 25-OH vitamin D deficiency was significantly associated with the cognitive and social-emotional development of infants.

Aim: Adequate vitamin B12 levels in infancy are crucial for normal psychomotor and cognitive development of infants. Our aim was to examine serum vitamin B12, folate and ferritin levels in exclusively breastfed healthy full‐term infants (age group: 1–6 months), and also investigate their correlation with maternal markers. Methods: A cross‐sectional study was conducted on 100 exclusively breastfed healthy full‐term infants (age group: 1–6 months) along with their lactating mothers. Serum vitamin B12, folate and ferritin levels were determined for each mother–infant dyad using enzyme‐linked immunosorbent assay. Results: The mean serum vitamin B12, folate and ferritin levels were 512 vs. 535 pg/mL, 15 vs. 12 ng/mL and 313 vs. 114 ng/mL in infants and mothers, respectively. Among 100 infants, 26 (26%) had lower vitamin B12 levels and 5 (5%) had inadequate folate levels. In addition, 22 (22%) of 100 lactating mothers were deficient in vitamin B12 levels and 14 (14%) had inadequate folate levels. We found a statistically significant positive correlation between infant and maternal vitamin B12 (r = 0.659, P < 0.001) and folate levels (r = 0.51, P < 0.001). Conclusion: Vitamin B12 deficiency was observed in 26% of infants and 22% of lactating mothers. Vitamin B12 and folate levels of infants were positively correlated with maternal levels in the state of Punjab, North‐West India. Our findings support that maternal vitamin B12 status can be used as a valuable predictor of infant vitamin B12 status. [ABSTRACT FROM AUTHOR]

This study deals with the quantitative assessment of nutritionally important fatty acids (FAs) in 94 indigenous rice (Oryza sativa ssp. indica) landraces of India which are critically endangered, being cultivated only by a handful of marginal farmers. Three modern high-yielding varieties and one local high-yielding farmers' variety were analysed for comparative assessment. Qualitative and quantitative analyses of FAs based on gas chromatography-mass spectrometric analysis of these varieties revealed their significant contribution to daily diet. Two 'case studies' were considered on the basis of individual FAs and nutritionally correlated FA parameters of the rice cultivars to isolate the most promising landraces, by clustering through linear discriminant function. These folk rice landraces may add important precursors to essential FAs in the staple diet and can provide for FA requirement in normal brain development in infants. We suggest incorporation of these landraces into India's food and agriculture policy, both for conserving the vanishing landraces and for ensuring nutritional security of the economically marginalized people.
