Introduction: Type 2 diabetes has become a chronic worldwide epidemic with advancing complications and has caused many premature deaths. Its global prevalence is about 9.7%, with 92.4 million suffering from the disease. Vitamin D level has been recently considered as an adjustable risk factor of cardiovascular diseases in individuals with type 2 diabetes.
Objectives: The aim of the current study is to investigate the frequency of vitamin D deficiency and the relationship between vitamin D serum levels and age in type 2 diabetes patients.
Patients and Methods: In this descriptive-analytic study, 101 type 2 diabetes patients of Imam Ali clinic in Shahrekord were investigated. Serum vitamin D levels of the participants were measured by DRG (USA) Elisa kits. The results were analyzed using SPSS software with a 95% confidence level.
Results: Of 101 studied patients, 32 were male and 69 were female. The average age of the subjects was 61.25 ± 11.75 years. The average age of the males was 63.09 ± 11.15 years and the average age of the females was 60.39 ± 12 years. Around 72 subjects were vitamin D deficient. No significant difference of vitamin D levels between males and females (P = 0.985) was detected. Serum vitamin D levels of type 2 diabetes patients were significantly positive correlated with their ages (r = 0.282, P = 0.004).
Conclusion: In the present study the prevalence of vitamin D deficiency in type 2 diabetes patients was 71.3 %. We found a positive significant relationship between the vitamin D level and age. It is possible that ageing process is not one of the causes of vitamin D deficiency.
