Hearing impairment in relation to vitamin D status in type 2 diabetic patients: A cross-sectional study

<b>Objectives: </b>To evaluate the association of serum 25 hydroxy vitamin D (25OHD) and hearing impairment type 2 diabetes mellitus (T2DM) patients. In addition, we aimed to examine whether T2DM-associated is correlated with severity diabetes.<br /> <b>Methods: </b>The present case-control study recruited adult patients T2DM healthy controls. Using pure-tone stimuli, used an audiometer assess thresholds air conduction in each ear separately.<br <b>Results: </b>84 32 volunteers were included. The 25OHD was lower than control (12.24±1.3 versus 23.19±5.69, respectively; p<0.001). prevalence deficiency 100% group, compared 25% group (p=0.001). exhibited higher at all tested frequencies (p<0.001). Diabetic had a significantly normal (11.7±1.2 12.6±1.2 ng/d; p=0.02). multivariate analysis demonstrated that level independent predictor loss among diabetic (β=-0.605; p=0.041).<br <b>Conclusions: </b>the highlights potential role developing setting T2DM. We found negative correlation between low-mid high amongst
