The Relationship Between HbA1c and 25-hidroxy Vitamin D Levels in Adult Diabetic Patients

Abstract

Objective: The aim of this study was to determine vitamin D levels in patients with type II Diabetes Mellitus who applied to the internal medicine diabetes and endocrinology policlinic of a training and research hospital, and to determine the relationship between HbA1c and 25-hydroxy vitamin D levels.
 Material and Method: Type II Diabetes Mellitus patients constituted the material of the study. The study was conducted between 2018-2019. The data were obtained from the hospital information management system. Those with bone-derived malignancies and pregnant women were excluded from the study. A total of 65 patients, 40 (61%) female and 25 (39%) males were included in the study. Statistical analyzes were made with the help of IBM SPSS for Windows 26.0 package program. The normal distribution was tested for the categories of factors affecting vitamin D levels. Accordingly, the hypothesis test was chosen and the descriptive statistics values suitable for the used hypothesis test were calculated. Variables indicated by measurement mean ± SD, smallest and largest; Variables that are represented by numbers are indicated by %. Pearson correlation coefficients were used to evaluate the correlations.
 Results: HbA1c and 25-hydroxy vitamin D levels were determined in the patients included in the study. HbA1C levels were found to be 9,023 ± 1.72 (%) higher than the normal values. 25-hydroxy vitamin D levels were 13.94±4.12 ng/ml and were lower than normal values. HbA1c levels and 25-hydroxy vitamin D levels were found to be statistically significant in type II Diabetes Mellitus patients (p
