摘要

The magnesium depletion score (MDS) is considered a new valuable predictor of body magnesium status. This study aimed to explore the association between MDS and PAD among participants aged ≥ 40 years on the National Health and Nutrition Examination Survey in 1999–2004. Survey-weighted multivariable logistic regression and restricted cubic spline models were used to assess the association between MDS and PAD. Survey-weighted multivariable logistic regression showed a significant positive association between MDS and the prevalence of PAD. For each unit increase in MDS, the risk of PAD increased by 24%. Compared to individuals with MDS = 0, those with MDS ≥ 3 had a 95% higher risk of PAD. Restricted triple spline analysis showed a linear dose–response relationship between MDS and PAD risk. Subgroup analysis indicated that this positive association was stronger in individuals aged > 60 years. Numerous future longitudinal cohort studies are required to validate our findings.
