Prevalence of and Risk Factors for Peripheral Artery Disease in Rural South Africa: A Cross-Sectional Analysis of the HAALSI Cohort.
Beidelman et al., J Am Heart Assoc 2023
DOI: 10.1161/JAHA.123.031780
Summary of New Findings:
The study provides new insights into the prevalence and risk factors of peripheral artery disease (PAD) in a rural South African population, highlighting a higher prevalence of PAD in younger age groups than previously reported. The findings indicate that 6.6% of the sample had clinical PAD, while a significant 44.7% had borderline PAD. Notably, age, diagnosed hypertension, and C-reactive protein levels were associated with an increased prevalence of clinical PAD.
Importance:
This research is important as it addresses the gap in population-representative data on PAD in sub-Saharan Africa, particularly from rural, low-income settings. It suggests that PAD is more prevalent in these communities than expected, especially among younger adults, which could have implications for public health strategies and resource allocation.
Contribution to Literature:
The study contributes to the literature by providing specific prevalence rates of PAD in a rural South African cohort, identifying associated risk factors, and challenging the assumption that traditional risk factors are predominant in this setting. It calls for further investigation into unique risk factors for PAD in low-income rural populations and suggests the need for expanded screening programs.
