Abstract

Objectives. We assessed 2 pathways through which dietary antioxidants may counter adverse effects of exposure to particulate matter less than 2.5 micrometers in diameter (PM 2.5 ) on blood pressure (BP): main (compensatory) and modifying (protective) models. Methods. We used 2002 to 2003 data from the Detroit Healthy Environments Partnership community survey conducted with a multiethnic sample of adults (n = 347) in low- to moderate-income, predominantly Hispanic and non-Hispanic Black neighborhoods in Detroit, Michigan. We used generalized estimating equations to test the effects of ambient exposure to PM 2.5 and dietary antioxidant intake on BP, with adjustment for multiple confounders. Results. Dietary antioxidant intake was inversely associated with systolic BP (b = -0.5; P 2.5 remained significant after accounting for antioxidant intakes. Exploratory analyses suggested potential modifying effects of antioxidant intake on associations between ambient PM 2.5 exposure and BP. Conclusions. Interventions to improve access to antioxidant-rich foods in polluted urban areas may be protective of cardiovascular health. However, efforts to reduce PM 2.5 exposure remain critical for cardiovascular health promotion. © 2015, American Public Health Association Inc. All rights reserved.
