Summary
Race and ethnicity are not independent risk factors for peripheral arterial disease (PAD). After adjusting for key health factors, disparities in PAD prevalence were not linked to ethnicity, suggesting social factors may play a role.
Area of Science:
- Cardiovascular Medicine
- Public Health
- Health Disparities
Background:
- Peripheral arterial disease (PAD) is a significant vascular condition.
- Understanding ethnic variations in PAD prevalence is crucial for targeted public health interventions.
- Previous studies suggested potential ethnic disparities in PAD, necessitating further investigation.
Purpose of the Study:
- To investigate whether race/ethnicity independently predicts the risk of developing peripheral arterial disease (PAD).
- To identify independent risk factors for PAD in a diverse patient population.
Main Methods:
- A cohort of 403 patients aged 55 years and older were screened for PAD in primary care clinics.
- Logistic regression analysis was employed to identify independent risk factors for PAD, adjusting for variables like age, smoking, diabetes, hypertension, and education.
Main Results:
- The prevalence of PAD was observed to be 22.8% in African American patients, 13.7% in Latino patients, and 13.2% in white patients (P = .06).
- After adjusting for atherosclerotic risk factors and education, neither African American nor Latino patients showed a statistically significant higher likelihood of PAD compared to white patients.
Conclusions:
- Ethnicity was not found to be an independent risk factor for peripheral arterial disease (PAD) when controlling for established risk factors.
- Further research is needed to explore the influence of social determinants and the primary care setting on ethnic variations in PAD outcomes.
