Vitamin D plays a crucial role in the growth and development of children, especially in maintaining bone health and supporting the immune system. This article explores the prevalence and causes of vitamin D deficiency among school-age children, highlighting its impact on physical and cognitive development. Factors contributing to the deficiency, such as limited sun exposure, poor dietary intake, and lifestyle habits, are discussed. The article also presents recommendations for early diagnosis, prevention, and intervention strategies to improve vitamin D levels in children and reduce associated health risks.
