Purpose: The purpose of this study was to identify the association between physical activity and vitamin D deficiency status among Korean adolescents.
Methods: This is cross-sectional analysis of Korean adolescents aged 10-18 years from the 5th Korea National Health and Nutrition Examination Survey(KNHANES 2010-2012; n=2,384). We estimated the prevalence of vitamin D deficiency and identified the correlations with the strength of physical activity. χ2 test, t-test, and multiple logistic regression using complex sample analysis were done. The odds ratio of vitamin D deficiency by physical activity was calculated using complex sample multivariate logistic regression analysis.
Results: The prevalence of vitamin D deficiency was 78.2%. The mean serum 25 (OH) D level in deficiency group and non-deficiency group was 14.4ng/mL, 23.7ng/mL respectively. Differences by age strata (the prevalence ranging from 68.5% to 86.3%) and gender (78.6% for boy and 84.5% for girl) were identified. Among adolescents aged 16-18 or girl in vigorous physical activity, a significant correlation between vitamin D deficiency and physical activity was observed, whereas no significant correlation were found among adolescents in moderate physical activity.
Conclusion: In conclusion, vigorous physical activity was associated with vitamin D deficit in Korean adolescents. Thus, intervention programs enhancing vigorous activity than moderate activity need to be developed in schools and community.
