Abstract

Research suggests that there is a significant impact of poverty on poor health outcomes. Poverty is associated with limited access to education and healthcare, increased exposure to violence, and chronic stress that contribute to the development of chronic diseases. The poverty and chronic disease relationship is potentially associated with chronically elevated stress biomarkers. The present study investigated the relationship between demographics, poverty (during childhood, young adulthood, and mid/late adulthood), allostatic load—a cumulative measure of system dysregulation—and the Charlson Comorbidity Index, a measure of chronic disease and mortality, using data from the Biopsychosocial and Religion and Health Study (BRHS; Lee et al., 2009) a subset of participants in the Adventist Health Study-2 cohort of Seventh-day Adventists. Of this subset 387 were examined on demographics, poverty, allostatic load (preclinical elevations in 13 biomarkers), chronic diseases and likelihood of mortality. Poverty experienced during childhood—but not during young adulthood or older adulthood—predicted chronic disease severity in late life. Ethnicity moderates the child poverty and AL relationship such that Black individuals have higher risk of elevated stress markers than their White counterparts. Allostatic load has a stronger impact on comorbidity in younger individuals, suggesting a premature aging effect.
