Abstract

Objective: The current research examined if there is a variance in the frequency of vitamin D deficiency or insufficiency among adults visiting the hospital for medical problems in winter and summer, and whether comorbidities have an impact on this. Material and Method: A total of 1155 patients (771 women, 384 men, mean age:48±15 years) who were admitted to the outpatient clinics of Istanbul Medeniyet University Goztepe Training and Research Hospital in August and February were tested for 25(OH)D levels for any reason were included. A 25(OH)D level of<20 ng/ml was stated as inadequacte, and 20–29 ng/ml was defined as insufficient. The two groups were examined in contrast in terms of vitamin D deficiency and insufficiency and the frequency of comorbidities. Results: 25(OH)D levels were inferior in the winter compared to the summer (16.1±12.5 ng/ml versus 22.2±15.8 ng/ml, p<0.001). Vitamin D deficiency was detected in 769 (66.6%) patients, and vitamin D insufficiency was detected in 226 (19.6%). Furthermore, 51.9% and 78.6% of patients had vitamin D deficiency (p< 0.001) and 27.3% and 13.1% had vitamin D insufficiency (p<0.001) during summer and winter, respectively. Prevalence rates of diabetes (60.1% and 39.9%, respectively, p=0.04) and hypertension (62.7% and 37.3%, accordingly, p<0.01) were more common in the winter compared to the summer. Conclusion: The findings of this research show that vitamin D insufficiency and deficiency are well-known health issues in Turkey, and although there has been some improvement, the problem persists even during the sunny seasons.

Özet

Amaç: Vitamin D [25(OH)D] eksikliği veya yetersizliğinin mevsimsel değişiklik gösterdiği bildirilmektedir. Bu çalışmada hastaneye başvuran erişkinlerde vitamin D eksikliği veya yetersizliği sıklığının kış ve yaz aylarında farklılık gösterip göstermediği ve komorbid durumlardan etkilenip etkilenmediği araştırıldı. Gereç ve Yöntem: Çalışmaya Ağustos 2014 (yaz grubu) ile Şubat 2015 (kış grubu) aylarında İstanbul Medeniyet Üniversitesi Göztepe Eğitim ve Araştırma Hastanesi polikliniklerine müracaat eden ve belirli bir sebeple 25(OH)D vitamini seviyelerine bakılan toplam 1155 olgu (771 kadın, 384 erkek, ortalama yaş: 48±15) dahil edildi. Vitamin D eksikliği<20 ng/ml, vitamin D yetersizligi 20-29 ng/ml olarak tanımlandı. Gruplar vitamin D ihtiyacı, yetersizliği ve komorbidite sıklıklarına göre karşılaştırıldı. Bulgular: Tüm olgularda ortalama vitamin D düzeyi 18,9±14,4 ng/ml (kadınlarda 18,9±15,5 ng/mL, erkeklerde 18,9±12,1 ng/mL) idi. Vitamin D düzeyleri; kış grubunda yaz grubuna göre daha düşük (16,1±12,5 ng/mL’ye karşılık 22,2±15,8 ng/mL, p<0,001) bulundu. Vitamin D eksikliği 769 hastada (%66,6), vitamin D yetersizliği 226 hastada (%19,6) saptandı. Vitamin D eksikliği %51,9’u yaz aylarında, %78,6’sı kış aylarında (p<0,001), D vitamini yetersizliği % 27,3’ü yaz aylarında ve %13,1’i kış aylarında (p<0,001) idi. Kış grubunda yaz grubuna göre diyabet (sırasıyla %60,1 ve %39,9, p=0,04) ve hipertansiyon sıklığı (sırasıyla %62,7 ve %37.3, p<0,01) yüksekti. Sonuç: Bu çalışmada güneşli yaz aylarında dahi populasyonumuzun yaklaşık yarısında, kış aylarında ise yaklaşık her 4 kişiden 3’ünde vitamin D eksikliği olduğu görülmüştür. Bu bulgular ülkemizde D vitamini eksiklik ve yetersizliğinin yaygın bir sağlık problemi olduğunu, güneşli mevsimlerde bu problemin kısmen azalsa da devam ettiğini göstermiştir.
