Objective: The purpose of this study is to establish the prevalence of vitamin D deficiency and their newborns and analyze the risk factors related to this deficiency. Methods: This is an observational, transversal, and prospective study. It included 191 puerperal women and their full-term newborns. Serum 25 hydroxyvitamin D values were analyzes by enzyme immunoassay. Results: 61% of the puerperal presented deficiency and 26% insufficiency of vitamin D. In the newborn group 98% showed deficiency and 66% of them presented severe deficiency. There is a positive correlation between the values of vitamin D in mothers and their newborns (r2 = 0.173 ng/ml; p = 0.017). The lowest levels were in autumn. (15.75 ng/mL mothers, 6 ng/mL newborns). There was no correlation between vitamin D levels in mothers and their dietary intake, maternal skin type, sun time exposure and prenatal body mass index. Conclusions: This is the first study that shows the existence of a high deficiency of vitamin D in Mexican mothers and their newborns. Copyright:
