Prevelance of Vitamin D and B12 Deficiency in Adolescence

Aylin Yetim Şahin, Ceyhun Tıkız, Firdevs Baş

Objective: Current guidelines recommend vitamin D supplementation during the adolescence period. Studies showed that the deficiencies of vitamins D and B12 are common in children in developing countries. On the other hand it is important to have optimum levels of vitamin D and B12 during the puberty. This study aims to evaluate the vitamin D and vitamin B12 levels of adolescents admitted to the outpatient department. Material and Method: The study was carried out in the Istanbul Medical Faculty, Department of Adolescent Health outpatient clinic between January to December 2014. The records of the adolescents aged 10-20 years were analyzed retrospectively. Of 187 adolescents were evaluated for vitamin 25 OH D and 219 were evaluated for vitamin B12. Results: Of 187 adolescents 56% had 25-OH vitamin D level ≤20 ng/ml, and 36% between 20-30 ng/ml. There were no statistically significant difference between genders or months in a year. Serum vitamin B12 levels were below the optimal level (<300 pg/mL) in one-third of adolescents (n=78). Conclusion: Vitamin D and vitamin B12 deficiencies were significantly high among adolescents attending to the outpatient department with various medical reasons. Adolescents should be considered risky in terms of lack of vitamin D and vitamin B12 levels, especially in metropolitan cities.

Ergenlik Döneminde D ve B12 Vitamin Eksikliklerinin Sıklığı

Aylin Yetim Şahin, Ceyhun Tıkız, Firdevs Baş

Amaç: D vitamininin kas-iskelet sistemi, immun sistem ve daha birçok mekanizma ile; B12 vitamininin ise özellikle nörokognitif fonksiyonlar olmak üzere yine çeşitli mekanizmalarla insan sağlığı üzerine önemli etkileri olduğu bilinmektedir. Bu yüzden hızlı gelişim ve değişim dönemi olan ergenlikte bu vitamin düzeylerinin istenilen sınırlar içerisinde olması önemlidir. Bu çalışmamızda amacımız ergenlerde D ve B12 vitamin düzeylerini değerlendirmekti. Gereç ve Yӧntem: İstanbul Tıp Fakültesi Ergen Sağlığı Bilim Dalı polikliniğine Ocak-Aralık 2014 tarihleri arasında nonspesifik yakınmalarla ya da kontrol amaçlı başvuran 10-20 yaş arası ergenlerin dosyaları retrospektif olarak incelendi. Serum 25 hidroksi D (25OHD) vitamin düzeyi (n=187) ve serum B12 düzeyi (n=219) ölçülmüş olan hastaların dosyaları değerlendirmeye alındı. Bulgular: Ergenlerin %56’sında serum 25OHD vitamin <20 ng/ml, %36’sında ise 20-30 ng/ml arasında idi. Cinsiyetlere ve aylara gӧre değerlendirildiğinde D vitamin düzeyleri arasında istatistiksel olarak anlamlı fark saptanmadı. Serum B12 vitamin düzeyi ergenlerin 1/3’ünde (n=78) optimal düzeyin altındaydı (<300 pg/mL). Sonuç: Ergenlerde D ve B12 vitamin eksiklikleri sıklığı yüksek bulunmuştur. Özellikle büyük şehirlerde ergenler bu vitamin eksiklikleri açısından riskli sayılmalı, D ve B12 vitamin düzeyleri yönünden değerlendirilmelidir. 

Keywords: Ergen, D vitamini, B12 vitamini, vitamin eksiklikleri
