Abstract

Introduction: Prevalence of vitamin D deficiency has been reported from all over the world since lower levels of vitamin D has been one of word’s problem in the 21st century; especially pregnant women are the most prominent one.

Objectives: This study aims to investigate the relationship between mothers’ vitamin D level with infants’ birth-weight and head circumference.

Patients and Methods: A cross-sectional study was conducted in the department of obstetrics and gynecology of Akbarabadi hospital during 2017-2018. Regarding two groups, infants’ three main characteristics including their weight, head circumference and height were studied.

Results: The mean blood levels of vitamin D in mothers with normal-born neonates were 15.23 ± 7.14 (ng/ mL) and in the mothers who gave birth to low-birth weight were 10.02 ± 8.06 (ng/mL), which was significantly lower than the mothers of normal-weight infants (P=0.018). The mean blood levels of vitamin D in mothers who gave birth to a normal head circumference neonate were 16.07 ± 8.1 (ng/mL) and in mothers with infants’ head circumference of less than 33 cm, was 9.87 ± 7.57 (ng/mL), which was significantly lower from mothers of normal-head circumference infants (P=0.007). The serum levels of vitamin D in mothers with normal-height infants were 14.74 ± 7.52 (ng/mL) and in the mothers with a height of less than 47 cm were 15.17 ± 7.91 (ng/mL), that does not suggest any significant difference (P=0.341). The mean serum vitamin D level in mothers who had normal vaginal delivery was lower than those with cesarean delivery, however there was no significant difference (P=0.174).

Conclusion: Nutrition improvement and prescribing vitamin D supplements can positively be effective in the way of curbing low-birth weight infants. Moreover, Exposure to sunlight and letting rays strike skin is essential for maintaining a healthy vitamin D status for girls and women.
