Korelasi Kadar Vitamin D dengan Panjang Badan Bayi 8- 10 Bulan di Jakarta Pusat = Correlation between Vitamin D Levels and Body Length on 8 to 10 Months Old Infants in Central Jakarta.

Vitamin D dapat mempengaruhi pertumbuhan tulang. Penelitian ini bertujuan untuk mengetahui korelasi kadar vitamin D dengan panjang badan bayi di Jakarta Pusat. Studi cross-sectional dilakukan terhadap 75 subjek yang memenuhi kriteria penelitian. Kadar vitamin D dalam serum diukur dengan metode CLIA (Chemiluminescence Immunoassay), dan panjang badan bayi diukur dengan teknik terstandarisasi dengan ketelitian 1mm oleh tenaga terlatih. Data dianalisis dengan uji Kolmogorov-Smirnov dan uji korelasi Pearson (korelasi bermakna jika p < 0,05). Hasil penelitian menunjukkan bahwa mayoritas subjek penelitian (80%) tidak memiliki asupan vitamin D yang cukup. Nilai tengah kadar vitamin D bayi berusia 8-10 bulan di Jakarta Pusat sebesar 26,4 ng/dL, sedangkan nilai tengah panjang badan bayi 70,63 cm. Hasil penelitian menunjukkan tidak terdapat korelasi bermakna antara kadar vitamin D dengan panjang badan bayi 8-10 bulan di Jakarta Pusat (p=0,563).

Vitamin D can influence bone growth. This study aims to determine the correlation between vitamin D levels and body length on 8 to 10 months old infants in Central Jakarta. Cross-sectional study was conducted on 75 infants which met the criteria. Serum vitamin D levels were measured with CLIA (Chemiluminescence Immunoassay), while body length was measured by antropometric standardized technique by trained personnel. The data was analyzed with Kolmogorov-Smirnov test and Pearson test (significant correlation if p < 0,05). The result shows that the majority of subjects (80%) do not have adequate vitamin D intake. The median value of vitamin D levels on 8 to 10 months old infants in Central Jakarta is 26,4 ng/dL, while the median value of body length is 70,63 cm. The result shows that there are no significant correlation between vitamin D levels and body length on 8 to 10 months old infants in Central Jakarta (p=0,563).
