The Retrospective Analysis of Vitamin D Levels of Pediatric Patients in a Small City Center in TurkeyTürkiye’de Küçük Bir Şehir Merkezinde Pediatrik Hastaların Vitamin D Seviyesinin Retrospektif Analizi

Objective: The aim of this study was to analyze the 25(OH)D3 levels and investigate a province’s pediatric vitamin D insufficiency and deficiency based on residence location. Materials and Methods: The pediatric patients who had 25(OH)D3 level results recorded in the patient file system from April 2013 to December 2014 were enrolled in the study. The demographic data of age, gender, address, and admission season of patients were recorded. The patients were divided into three group according to their 25(OH)D3 levels: Group 1 (deficiency, < 20 ng/mL); Group 2 (insufficiency, 20–29.9 ng/mL); and Group 3 (normal, ≥ 30 ng/mL). Results: Seven hundred and seventy-five patients were included in the study. The average age of the patients was 14.5 ± 9 (1–123) months. The mean vitamin D levels indicated no statistically significant difference among the seasons (p = 0.751) and residence locations (p = 0.183). Conclusion: The results of this study indicate that vitamin D levels are not affected by residence location. Similar studies need to be carried out in major cities.( Sakarya Med J 2016, 6(3):136-140 ) Keywords: childhood, seasons, residence location, vitamin D
