Correlation between obesity and serum 25-hydroxyvitamin D levels in patients with type 2 diabetes

Abstract

[Objective] The paper analyzes the correlation of vitamin D level with obesity degree and serum 25-hydroxyvitamin D level in patients with type 2 diabetes mellitus (T2DM) through clinical case studies, which can provide clinical guidance for obese T2DM patients' weight control to lower their risk of developing metabolic illnesses. [Methods] A total of 249 patients with T2DM were chosen from among those hospitalized at Lanzhou University's First Hospital between April and September of 2023. The serum 25-hydroxyvitamin D level, body fat rate, fasting blood glucose, and fasting insulin of the subjects were detected, and 198 T2DM patients with low serum 25-hydroxyvitamin D levels were selected as the observation group. 51 T2DM patients with normal serum 25-hydroxyvitamin D levels were selected as the control group, and the correlation between type 2 diabetes mellitus and vitamin D levels and obesity was analyzed. [Results] Obesity and serum vitamin D insufficiency are associated with type 2 diabetes. Both vitamin D deficiency and obesity eventually lead to T2D, endocrine disorders, and other common diseases. [Conclusions] Low plasma 25-hydroxyvitamin D (25[OH]D) concentration and high BMI are correlated with an increased risk of diabetes.
