- The study refined the pediatric EVIDENCe-Q questionnaire by adding weighted variables for sun exposure during peak UVB hours and BMI z-score to improve prediction of vitamin D deficiency in children.
- Among 354 children, vitamin D deficiency (<10 ng/mL) was found in 6.8%, insufficiency (<20 ng/mL) in 38.1%, and levels below 30 ng/mL in 74.7%. The sun + BMI-weighted model showed significant discrimination and correlation with serum 25-OH-D levels.
- The enhanced questionnaire, particularly the sun + BMI-weighted version, offers a practical noninvasive screening tool, though with moderate accuracy, for identifying children at risk of vitamin D deficiency.
