*Model 1 adjusted for age, sex, and BMI.

^†Model 2 adjusted for Model 1 + smoking status, alcohol consumption status, history of pregnancy, household monthly income, and PCP use within the last 2 days.

SE: standard error, ∑DEHP: sum of MEHHP, MEOHP, and MECPP.

Sum of frequencies of using PCPs: less than once a month within the last 3 months, once a month within the last 3 months, twice or three times a month within the last 3 months, once or twice a week within the last 3 months, three or five times a week within the last 3 months, six times a week and more within the last 3 months.
