Adjusted mean difference (95% CI) of gestational weight gain z scores associated with an IQR-increase in urinary phthalate biomarkers or a 1-quartile increase in the phthalate mixture, stratified by pre-pregnancy BMI category in the LIFECODES cohort (n = 379).

Abbreviations: IQR, interquartile range; CI, Confidence Interval; BMI, Body Mass Index;DEHP, Summed Di-2-ethylhexyl phthalate metabolites; MBzP, Mono-benzyl phthalate; MBP, Mono-n-butyl phthalate; MiBP, Mono-isobutyl phthalate; MEP, Mono-ethyl phthalate; MCPP, Mono-(3-carboxypropyl) phthalate.

Models for rate of gestational weight gain, gestational weight gain adequacy ratio, and gestational weight gain z score adjusted for maternal age, insurance, race and ethnicity, education, parity, and pre-pregnancy BMI. Models for total gestation weight gain additionally adjusted for gestational age at last recorded weight. Phthalate metabolites were natural log transformed and IQR-standardized.
