Summary
Insulin resistance syndrome components are linked to heart disease in American Indians. Specific clusters of metabolic factors and blood pressure correlate with coronary heart disease risk.
Area of Science:
- Cardiovascular epidemiology
- Metabolic syndrome research
- Indigenous health studies
Background:
- Insulin resistance syndrome (IRS) is a cluster of metabolic abnormalities.
- IRS components are associated with increased risk of macrovascular disease.
- Understanding IRS interrelationships is crucial for targeted interventions.
Purpose of the Study:
- To investigate the relationships between IRS components.
- To examine the association of IRS clusters with macrovascular disease in American Indians.
- To identify key risk factors for cardiovascular disease within this population.
Main Methods:
- Analysis of data from 4,228 American Indian participants (aged 45-74) in the Strong Heart Study.
- Utilized factor analysis to identify clusters of IRS variables.
- Assessed associations between identified clusters and coronary heart disease (CHD) and peripheral vascular disease (PVD).
Main Results:
- In nondiabetics, glucose, BMI, and insulin formed a significant cluster associated with CHD.
- Blood pressure clusters were linked to CHD in nondiabetics but not in diabetics.
- HDL cholesterol, triglycerides, and glucose cluster associated with CHD in diabetic women and PVD in both sexes.
Conclusions:
- Specific clusters of insulin resistance syndrome components are associated with macrovascular disease in American Indians.
- Findings highlight distinct risk factor profiles for coronary and peripheral vascular disease.
- Understanding these associations can inform strategies for managing metabolic disorders and cardiovascular risk in this population.
