Abstract
Cross-sectional studies have linked vitamin D deficiency and alteration of calcium levels to an increased incidence of type 2 diabetes and insulin resistance. This study investigated a possible correlation between blood vitamin D and calcium levels with insulin resistance and beta-cell dysfunction in type 2 diabetes, pre-diabetes, and healthy individuals. This cross-sectional study involved 300 participants. Participants were divided into three groups (n=100), type 2diabetic, prediabetic, and healthy. In order to measure insulin resistance and β –cell function, the HOMA IR and HOMA B were assessed, respectively. Also, the other parameters such as serum 25(OH)D, blood insulin (FPI), glucose (FBS), HbA1c, and calcium were assessed in this study. In simple regression analysis, a high vitamin D level is linked to lower levels of FBS, HbA1c, Insulin, and HOMA IR, and higher levels of HOMA B. Calcium has a positive connection with FBS and HbA1c and a negative connection with insulin level and HOMAB. Hypovitaminosis D may substantially influence diabetes patients' glycemic dysregulation. "An increased incidence of type 2 diabetes has been related to a disruption in calcium homeostasis. All in all an increament in calcium levels may have a role in developing type 2 diabetes".
