Relationship between LE8 score and peripheral arterial disease from NHANES perspective

Background: This study examined the link between the Life's Essential 8 (LE8) metric and peripheral artery disease (PAD) prevalence in the U.S. Patients and methods: This population-based prospective cohort study analyzed data from 6,076 participants aged 20 years and older from the National Health and Nutrition Examination Survey (NHANES) conducted between 1999 and 2004. LE8 scores were categorized into low, moderate, and high cardiovascular health (CVH) levels. Multivariable weighted logistic regression and subgroup analyses were performed to examine the relationship between CVH and PAD, adjusting for demographic and clinical variables. Results: In final analysis, a total of 6,076 individuals were included, with a mean age of 59.41±12.80 years and 51.3% (n=3,115) being male. The prevalence of PAD was 6.9% (n=418). After adjusting for confounding factors, compared to participants with low CVH, those with moderate CVH had a 34% lower risk of PAD (OR: 0.66, 95% CI: 0.53-0.82), and those with high CVH had a 62% lower risk of PAD (OR: 0.38, 95% CI: 0.25-0.58). Conclusions: In conclusion, we report that lower CVH scores are associated with higher PAD risk among U.S. adults. These findings may contribute to the prevention strategies for PAD.
