Niveles de vitamina D en sangre materna y su relación con el consumo de pescado y los parámetros antropométricos de los recién nacidos en una cohorte de parejas madre/hijos de Sevilla

Introduction

To compare maternal vitamin D levels with the area of residence or the consumption of fish, as well as its relationship with the weight, length and cranial perimeter of babies.

Materials and methods

Cohort of 100 mother–child pairs (n = 100) from the province of Seville (Virgen del Rocío University Hospital and Valme University Hospital). In maternal blood samples (gestational age ≥ 40 weeks) 25(OH)D levels have been measured by chemiluminescence. Anthropometric measurements of the babies were made using standard methods.

Results

Regarding vitamin D levels, 54% had deficient values, 26% insufficient and 20% sufficient values. After a multiple regression analysis, it is observed that there is no significant difference between maternal vitamin D levels, the length and the cephalic perimeter of the babies, however, there is a difference with the birth weight (P < .05). When applying the t-Student and the Wilcoxon test, there is no relationship between vitamin D levels and the area of residence or with maternal fish consumption (both P > .05).

Conclusions

Eighty percent of mothers present deficient and insufficient values of vitamin D. There is no correlation between this parameter and the length and cephalic perimeter of the baby, observing a negative correlation with birth weight. No correlation was observed between the area of residence or the consumption of fish and vitamin D levels in mothers. We suggest dietary supplements for pregnant mothers and monitoring of vitamin D levels in babies.
