Relationship between levels of serum 25- hydroxyvitamin D with gender and visual acuity students of junior high school
Background: Visual disturbance can be caused by external factors, that is, the lack of outdoor activities and a positive correlation between the length of outdoor activities and vitamin D levels. The aim of this research was to examine the correlation between serum 25-hydroxyvitamin D level, sex and visual acuity.Methods: This research uses cross-sectional approach, conducted in junior high school 16,18 of Semarang. Purposive sampling method, the analysis is done the chi square test.Results: There is a correlation between sex and serum 25-hydroxyvitamin D at junior high school 16 (p=0.001, c=13.42) and junior high school 18 (p=0.001, c=13.42). There is a correlation between serum 25-hydroxyvitamin D and visual acuity at junior high school 16 (p=0.302, c=4.868). There is no correlation between serum 25-hydroxyvitamin D and visual acuity at Junior High School 18 (p=0.302, c=4.868).Conclusion: Serum 25-hydroxyvitamin D is related to sex, 25-hydroxyvitamin D is correlated with a decrease in vision acuity. Serum 25-hydroxyvitamin D is not correlated with a decrease in vision acuity
