Abstract
AbstractBackground: The lived experience of ethnicity is a source of psychosocial stress.
Objectives: Estimate the association between ethnicity and allostatic load (AL) by measuring the physiological cost of prolonged stress response, reflected in measurable cardiovascular, metabolic, and immune system acclimating changes.
Methods: Adult participants were selected from the National Health and Nutrition Examination Survey (NHANES) 2017-2018 survey cycle and categorized into four ethnic groups: White, African-American (AA), Mexican-/Hispanic-American (MHA), and Asian-American (AsA). AL was calculated using 10 biomarkers representing the regulatory status of cardiovascular, metabolic, and immune systems. Poisson regression analyses produced age-education-adjusted prevalence ratios (PRs) of AL stratified by gender, and age-adjusted PRs stratified by both gender and education.
Results: Adjusting for age and education, AA women had the highest PRs (1.59) in the study, and AsA men had the highest PR (1.4) among men. Stratifying by both gender and education, highlighted the heterogeneity of effect that educational attainment has on the AL of each ethnicity by gender.
Conclusions: Complex relationships exist between gender, ethnicity, education, and allostatic load that underscore the extensive impact of social disparities on health and socioeconomic security, and highlight the need for disaggregation of ethnic subgroups to better understand these relationships.
