Factors associated with the serum 25-hydroxyvitamin D levels in adults

This study identified several key variables associated with serum 25(OH)D levels in adults. These findings provide important targets for designing health education programs aimed at reducing the prevalence of vitamin D insufficiency. Future community-based research should consider incorporating additional determinants of vitamin D status, including quantified sunlight exposure, dietary intake of vitamin D-rich foods, and supplementation patterns. Accounting for these broader lifestyle and environmental factors may enable subsequent studies to generate more robust insights into the multifactorial nature of vitamin D regulation and inform more effective public health strategies.
