Exposure to air pollution disproportionately affects racial/ethnic minorities that could contribute health inequalities including metabolic disorders. However, most existing studies used a static assessment of exposure (mostly using the residential address) and do not account for activity space when modelling pollution. The aim this study is understand how impacts disorders biomarkers, effect differs according ethnicity, first time compare these findings with two methods assessment: dynamic measures.Among Community Mine study, cross-sectional conducted in San Diego County, insulin resistance, diabetes, hypertension, obesity, dyslipidemia, syndrome (MetS) were assessed. (PM2.5, NO2, traffic) was calculated measures around home, mobility derived from Global Positioning Systems (GPS) traces kernel density estimators variability across time. Associations quantified generalized estimating equation models clustered nature data.Among 552 participants (mean age 58.7 years, 42% Hispanic/Latino), Hispanics/Latinos had higher PM2.5 compared non-Hispanics measures. In contrast, less For all participants, NO2 associated increased resistance cholesterol levels, risk dyslipidemia MetS (RR 1.17, 95% CI: 1.07-1.28; RR 1.21, 1.12-1.30, respectively). association between differed by Hispanic/Latino ethnicity.These results highlight importance considering people's daily assessing impact on health.
