Estimated associations for ∑DEHP and MnBP with IR markers.

β and 95% confidence interval (CI) were obtained in single pollutant models of ∑DEHP and MnBP. Changes in glucose, insulin, and HOMA indices by a log change of ∑DEHP and MnBP were obtained by model; Model 1 adjusted for age, sex, BMI, educational attainment, exercise, and cotinine level; model 2 adjusted for model 1 variables plus PM10 on lag day 4, O3 on lag day 5, NO2 on lag day 7, and outdoor temperature and dew point in the day; model 3 adjusted for model 2 variables plus total caloric and fat intake. ∑DEHP, molar sum of mono-(2-ethyl-5-hydroxyhexyl) phthalate (MEHHP) and mono-(2-ethyl-5-oxohexyl) phthalate (MEOHP); MnBP, mono-n-butyl phthalate; HOMA, homeostatic model assessment.
