Abstract

Amaç: D vitamini, bazı gıdalarda bulunan ve güneş ışığına maruz kalan öncülerinden sentezlenebilen yağda çözünen bir vitamindir. Serum 25-hidroksi vitamin D (25-OH Vit D) konsantrasyonunun Vitamin D seviyesinin en iyi göstergesi olduğu bilinmektedir. D vitamininin ana kaynağı güneş ışığına maruz kalan ciltten sentez edilmesidir. Çalışmada Van'da hastanemize başvuran hastaların D vitamini düzeylerini geriye yönelik taradık. 25-OH vit D düzeylerinin yaş, cinsiyet ve mevsimsel farklılıkları arasındaki ilişkiyi araştırdık. 

Yöntem: Yüzüncü Yıl Üniversitesi Tıp Fakültesi Dursun Odabaş Tıp Merkezine başvuran 01.01.2013 - 01.01.2014 tarihleri arasında 25-OH vit D düzeyleri tespit edilen kriterleri sağlayan sonuçlar dahil edildi. 

Bulgular: Erkeklerin yaş ortalaması (n = 306) 46.65 ± 16.62, kadınlarda (n = 1613) 43.58 ± 15.03 olarak bulundu. Erkeklerde ortalama 25-OH vit D 18.95 ± 7.93 ng / mL ve kadınlarda 14.79 ± 9.42 ng / ml olarak bulundu. Erkeklerin 25-OH D vitamini düzeyleri kadınlardan anlamlı derecede yüksek bulundu (p <0.05). Mevsime göre 25-OH D vitamini seviyeleri analiz edildiğinde, yaz mevsimi için 25-OH Vitamin D ortalaması kış mevsimine ya da Sonbahar-İlkbahar aylarına göre anlamlı olarak yüksekti (p = 0,006). 

Sonuç: Her ne kadar Van, konumu itibariyle en çok güneş alan şehirler arasında olsa da, tüm mevsimler ve yaş gruplarına göre vitamin D düzeylerini düşük olduğunu düşünüyoruz. Bu bulgulara göre, Van ilindeki ve çevresindeki vitamin D eksikliğinin düzelmesi için hem beslenme desteğinin hem de D vitamini desteğinin önemli olduğu sonucuna vardık.

Evaluation of seasonal relationship with vitamin D levels in the Van region

Abstract

Objectives:
Vitamin D is a fat-soluble vitamin which is found in certain foods and can be
synthesized from its precursors with exposure to sunlight. It is known that
serum 25-hydroxy vitamin D (25-OH Vit D) concentration is the best indicator of
Vitamin D level. Main source of Vitamin D is the synthesis to the skin with
sunlight exposure. In our study we investigated the vitamin D levels of
patients administered to our hospital in Van. We aimed to determine any
significant difference between age, sex and seasonal differences of the 25-OH
vit D levels.

Materials and Method: Patients
admitted to Yuzuncu Yil University Faculty of Medicine Dursun Odabas Medical
Hospital from 01.01.2013 to 01.01.2014 with 25-OH vit D levels were determined
and evaluated [JB1] respectively.

Results: Mean
age for males (n=306) was found as 46.65±16.62 and for females (n=1613) as
43.58±15.03. Mean 25-OH vit D in males was found as 18.95±7.93 ng/mL and in
females it was found as 14.79±9.42 ng/ml. 25-OH vit D levels of males were found
significantly higher than that of females (p<0.05). When 25-OH vit D levels
were analyzed according to season, a mean of 25-OH vit D for the summer season
was found significantly higher than those of the winter or autumn-spring months
(p=0.006). Although Van receives one of the highest amount of sunlight due to
its geographical position, we consider that there exists a deficiency in all
age groups in the society, for all seasons.

Conclusions:
According to these findings we conclude that both nutritional support and
Vitamin D supplementation is important for recovery of vitamin D deficiency in
and around the city of Van.
