Correlation between vitamin D intake with level of 25-hydroxy vitamin D serum maternal

Vitamin D deficiency is a health problem that is of concern at this time. During pregnancy, vitamin D is associated with fetal growth and development, wherein the 25(OH)D level of the fetus is completely dependent on the mother's supply. This study aims to examine the relationship between vitamin D intake and maternal serum 25(OH)D levels. This research uses a cross-sectional design. Data collection was carried out in samples at Hermina Hospital, BMC and Army Hospital in June-December 2022. The sampling technique used consecutive sampling, totaling 40 term pregnant women. Data collection was carried out by taking maternal blood. Data on vitamin D intake were obtained from interviews using the FFQ questionnaire. Maternal serum was examined using the ELISA method at the Unand Biomedical Laboratory. The test used is Pearson correlation The results showed that the mean intake of vitamin D and levels of 25(OH)D in maternal serum were 16.54 ± 2.99 mcg, 14.74 ± 4.93 ng/ml. The relationship between vitamin D intake and maternal serum 25(OH)D levels with a value of r=0.379 was significantly ρ=0.016. The conclusion of this study was that the correlation between vitamin D intake and maternal serum 25(OH)D levels was significantly correlated
