Abstract

The occurrence of Down syndrome and chromosomal nondysjunction is more prevalent in the progeny of mothers who conceive at an advanced age. The primary objectives of the study were to investigate the prevalence of Vitamin D deficiency through the evaluation of 25(OH) Vitamin D levels in children diagnosed with Down syndrome. Material and Methods: This study employed a prospective descriptive design. The research was carried out at the Department of Pediatrics, Gayatri Vidya Parishad Institute of Health Care and Medical Technology, Visakhapatnam, Andhra Pradesh, which is a medical center providing specialized care in India. The study spanned from May 2022 to April 2023. A total of 50 children who were thought to have Down syndrome were subjected to examinations. Results: A total of 50 youngsters who were thought to have Down syndrome were subjected to interviews. Two individuals exhibited a cytogenetic profile consistent with Down syndrome; nevertheless, they expressed a lack of willingness to undergo additional diagnostic procedures. Three individuals exhibited clinical characteristics consistent with Down syndrome, however, they declined to provide a blood sample for subsequent diagnostic testing and verification. The cytogenetic study of the youngster, consisting of 50 samples, did not reveal any evidence of Down syndrome. The analysis comprised a total of 50 children, consisting of 40 boys and 10 girls. The following table and graph provide an overview of the demographic composition of the children in terms of age and gender. Conclusion: Children with Down syndrome had a prevalence of 25 (OH) Vitamin D deficiency of 26.8%. Deficiencies in 25 (OH) Vitamin D had no appreciable effect on these children's height, bone age, or other biochemical indicators.
