Abstract

We aimed to investigate whether CDT and 25-hydroxyvitamin D (25OHD) level are predictors for sun exposure and walking duration, and aimed to investigate whether CDT is reliable in low educated (LE) elderly. Material and Methods: A total of 185 LE patients without dementia above the age of 65 who had applied to internal medicine clinic were included in the study. The patients’ demographic data, sun exposure, walking duration, a history of coronary artery disease (CAD) and the number of falls were recorded. Clock drawing was measured using Manos scoring system. Results: The study population included 127 (68.6%) males with a mean age of 73 ± 6 years and 58 (31.4%) females with a mean age of 70 ± 5 years. According to Manos scoring system a total of 90 (48.6%) subjects had a CDT score of 0, 70 (37.9%) subjects had a CDT score of 1-9 and 25 (13.5%) subjects had a CDT score of 10. The mean vitamin D level of the patients was 18.4 ± 7.3 ng/mL. Vitamin D levels and CDT scores were predictive for sun exposure, duration of walking, number of falls and CAD. Conclusion: CDT scores of LE subjects were unreliable to demonstrate cognitive functions. This study has shown that vitamin D levels to be more potent predictor than CDT scores to demonstrate sun exposure, walking duration, numbers of falls and the incidence of CAD in LE subjects.

Düşük Eğitim Düzeyli Yaşlı Hastalarda D Vitamin ve Saat Çizme Testinin Değerlendirilmesi

Abstract

Amaç: Saat çizme testi (SÇT) kognitif fonksiyonları değerlendirmede kullanılan kısa, pratik ve güvenli bir testtir. Biz SÇT ile 25-hidroksivitamin D seviyesinin güneşe maruziyet ve yürüme süresi için prediktif olup olmadığını ve SÇT’nin düşük eğitim düzeyli (DE) yaşlılarda güvenilir olup olmadığını araştırmayı amaçladık.
Materyal ve Metod: İç hastalıkları kliniğine başvuran 65 yaş üzeri demansı olmayan 185 DE hasta bu çalışmaya dahil edildi. Hastaların demografik verileri, güneş maruziyetleri, yürüme süreleri, koroner kalp hastalığı (KKH) öyküsü ve düşme sayısı kaydedildi. SÇT, Manos skorlama sistemi kullanılarak ölçüldü. 
Bulgular: Çalışma populasyonu yaş ortalaması 73 ± 6 yıl olan 127 (%68.6) erkek ve yaş ortalaması 70 ± 5 yıl olan 58 (%31.4) kadın hastayı içeriyordu. Manos skorlama sistemine göre, 90 (%48.6) kişinin CDT skoru 0, 70 (%37.9) kişinin CDT skoru 1-9 arası ve 25 (%13.5) kişinin CDT skoru 10 idi. Hastaların ortalama D vitamin düzeyi 18.4 ± 7.3 ng/mL idi. D vitamin seviyesi ve SÇT skorları güneş maruziyeti, yürüme süresi ve düşme sayısı ve KKH için tahmin edici değerdeydi.
Sonuç: DE kişilerin SÇT skorları bilinç fonksiyonlarını göstermede güvenilir değildir. Bu çalışma gösterdi ki DE bireylerde D vitamin seviyeleri güneş maruziyeti, yürüme süresi, düşme sayısı ve KKH sıklığını göstermede SÇT skorundan daha güçlüdür.
