Abstract
Objective:
To determine the relationship between serum
vitamin D levels in third trimester mothers and newborn
birthttweight.
Method:
The study was conducted at the maternity ward
of Dr. Zainoel Abidin General Hospital in Banda Aceh,
Indonesia. Maternal and infant serum vitamin D levels
were measured using the Automatic Chemiluminescence
Immunoassay Analyzer (CLIA) method. Blood samples were
collected from mothers in the third trimester and from
infants after delivery. Spearman's correlation rank test was
employed with a con
fi
dence level of 95%. Vitamin D levels
were categorized as suf
fi
cient, insuf
fi
cient, and de
fi
cient.
Results:
A total of 39 pregnant women with an average
age of 30.38 ± 6.21 years participated in the study, with a
predominance of 38-39 weeks of gestation (35.9%). The
mean vitamin D levels in mothers and neonates were 17.4
ng/mL and 17.6 ng/mL, respectively (p = 0.003, R = 0.462).
The average birth weight of the babies was 3,100 grams,
ranging from 2,100 grams to 4,200 grams (p = 0.185, R =
0.217). Both variables showed a positive correlation with
varying strength of the relationship.
