A total of 1688 participants were included in this cross-sectional investigation. Spearman's correlation analysis was used to assess the relationships between candidate indicators and PDM. The impact of indicators on PDM risk was determined by multivariate logistic regression. The receiver operating characteristic (ROC) analysis was performed to evaluate the prognostic value of indicators. Our study indicated a positive correlation between WC, BMI, and 25-OH-D3 and PDM. WC (OR = 1.05, 95% CI = 1.04-1.06, <i>p</i> < 0.001), BMI (OR = 1.11, 95% CI = 1.08-1.15, <i>p</i> < 0.001), and 25-OH-D3 (OR = 1.01, 95% CI = 1.00-1.02, <i>p</i> = 0.037) and an increased risk of PDM.
