Background: Vitamin D plays a pivotal role in supporting the immune system, helping to reduce the risk of infections and certain autoimmune diseases. Adequate vitamin D levels may be associated with a reduced risk of certain health conditions like pre-eclampsia, gestational diabetes, and postpartum depression. Brittle bones, osteoporosis in the elderly, and osteomalacia in young children are all symptoms of vitamin D insufficiency. Additionally, it contributes to problems linked to gum disease, including an increase in dental cavities, alveolar bone loss around the teeth, and other problems. It could lead to depression, tiredness, and a loss of appetite. In this study, urban children and adolescents in Dhaka city, Bangladesh are examined for vitamin D deficiency, insufficiency, and sufficiency. Methods: The Study was a cross-sectional study conducted under Dhaka National Medical College and Hospital, Dhaka and additionally included two other health centers Medinova Medical Services and Monoara General Hospital Service Golap bag, Dhaka from October 2020 to November 2021. The study location was at the 3 (Three) different hospitals which was located in Dhaka City. In this cross-sectional study, Participants will be selected purposively and conveniently based on the age categories from 0 - 19 years of age at the outdoor department of the hospital. The study included the secondary dataset of ambulatory individuals who came to the 3 (three) hospitals, randomly to evaluate serum vitamin D levels on referral from a general out-patient-department (OPD). They were examined for laboratory findings of serum 25 hydroxyvitamin D levels to determine vitamin D deficiency, insufficiency, and sufficiency among children and adolescent groups of both male and female Sex. Results: A total of 6394 individuals with a diverse age group were statistically examined for laboratory findings of serum vitamin D levels. Vitamin D deficiency was observed in 40.58% of individuals with a mean log of 1.01 ± 0.18 ng/ml serum vitamin D levels, vitamin D insufficiency in 30.93% of individuals with a mean log of 1.38 ± 0.05 ng/ml serum vitamin D levels and vitamin D sufficiency in 19.49% individuals with a mean log of 1.63 ± 0.12 ng/ml serum vitamin D levels. The highest percentage of individuals deficient in vitamin D were children and adolescents of age ranging between 15 to 19 years. Conclusion: The findings of vitamin D deficiency in children and adolescents direct higher authorities in the public health sector to take immediate steps to screen, intervene and educate high-risk populations incorporating vitamin D supplements to establish preventive and therapeutic measures.
