Objective: Vitamin
D has important implications for human health. The aim of this research was to
investigate retrospectively how the laboratory data of vitamin D level changes
according to sex and age groups during winter and summer
months.

Materials
and
Methods: Study groups composed of woman and men were
formed according to age groups of 0-4 years, 5-12 years, 13-18 years, 19-49
years, 50-90 years. For this purpose, between July and October, the data of 354
male and 1105 female patients, of a total of 1459 subjects were taken. Between November
and March, data of 544 men and of 1579 women, of total 2123 persons were analyzed.
In total, data of 3582 personswere screened retrospectively from laboratory
automation data. Blood samples (Containing EDTA) were analyzed by Thermo uHPLC
(Ultra High Performance Liquid Chromatography) after preliminary processing the
results of calibration and control are found appropriate.

Results: Vitamin
D levels of automation data were scanned in different age and gender groups in summer
months where sunny days were long and numerous and in winter days where sunny
days were short and fewer. The cut-off value in the scan was accepted as 20
ng/dL (limit value). Accordingly, when all age groups were considered,there was
a decrease of 36.4% for men and 38.2% for women in Vitamin D levels in winter
months compared to that in summer months.







Conclusion:
In this research, it has been observed that vitamin D levels in winter months
decrease by a rate of 1/3. Accordingly, when vitamin D levels are below 20
ng/ml due to inadequate exposure to sunlight, it may be recommended that people
be exposed to sunlight in sunny days or take D vitamin preparations.

Amaç: D vitamini [25(OH)D3] insan sağlığı
açısından önemli fonksiyonlara sahiptir. Bu araştırmada yaz ve kış aylarını
içeren dönemlerde yaş ve cins gruplarına göre 25(OH)D3 laboratuvar verilerinin geriye dönük olarak
incelenmesiyle ne oranda değişim gösterdiğinin ortaya konulması amaçlandı.

Gereç ve Yöntem:

Çalışmaya 
0-5, 5-12, 13-18, 19-49, 50-90 yaş aralığında bulunan kadın ve erkek olgular
alındı. Bu amaçla
temmuz-ekim
ayları dahil dönemi içeren 354 erkek ve 1105 kadın olmak üzere toplam 1459
kişi, kasım-mart ayları dahil dönemi içeren ise 544 erkek ve 1579 kadın olmak
üzere toplam 2123 kişi ve genel toplamda 3582 kişinin 25(OH)D3düzeyleri  geriye dönük olarak hastanemiz biyokimya laboratuvar
otomasyon verilerinden taranarak incelendi. 
EDTA’lı tüplere alınan kan örnekleri, ön
işlem sonrası Thermo uHPLC (Ultra high performans likit
kromatografisi) cihazında kalibrasyon ve control sonuçlarının uygun bulunmasını
takiben analizleri gerçekleştirildi.

Bulgular:

Değişik yaş ve cins gruplarında
güneşli günlerin uzun ve çok sayıda olduğu yaz ayları ile güneşli günlerin kısa
ve az sayıda olduğu kış aylarını içeren dönemlerdeki 25(OH)D3 düzeylerinin otomasyon
verileri taranmıştır. Taramada cut-off değeri 20 ng/dl (sınır değer)
alınmıştır. Verilerin arasındaki farkın anlamlılığı ortaya konmuştur. Buna göre
tüm yaş grupları göz önüne alındığında yaz aylarına göre kış aylarında ortalama
olarak erkeklerde % 36.4, kadınlarda
ise  % 38.2 oranında bir azalmanın olduğu
gözlenmektedir.











Sonuç:
Yapılan bu çalışma ile kış aylarında D vitamin düzeylerinde
1/3’e varan oranlarda
azalmanın olduğu
gözlemlenmiştir. Buna göre 20 ng/ml’nin altındaki olguların güneş ışığından
yeterince faydalanmadıkları bu nedenle güneşli günlerde yeterince güneş ışığına
maruz kalmaları veya D vitamini desteği almaları önerilebilir.
