Concentrations (geometric mean, GM) of maternal and childrenʼs urinary phthalates (μg/g creatinine), HOME scores, and intelligence quotients (IQs) at the four follow-up points.

aTen pregnant women could not provide sufficient urine samples; the total numbers of pregnant women were 100 subjects.bMixed model was used to test for age trend of childrenʼs urinary phthalate levels, HOME score, and IQ.cΣMEHP = MEHP + MEHHP + MEOHP.dIQ: The mental development index scores of the Bayley Scales were used to assess the IQ of children aged 2–3 years. The Wechsler Scales were to evaluate the IQ of children aged 5–12 years.Concentrations (geometric mean, GM) of maternal and childrenʼs urinary phthalates (μg/g creatinine), HOME scores, and intelligence quotients (IQs) at the four follow-up points.
