Free and total urinary phthalate metabolite concentrations among pregnant women from the Healthy Baby Cohort (HBC), China

Season-dependent concentrations of urinary phthalate metabolites among Chinese pregnant women: Repeated measures analysis

“…Regarding maternal factors, all DEHP metabolites were positively related to parity in our study, which was partly consistent with Zhu et al (2016). Furthermore, Zhu et al (2016) also found significant relationships of parity with some low molecular metabolites (MEP and MBP). Despite these positive correlations, the only negative relationship was found between parity and MEP, according to Arbuckle et al (2014).…”

“…However, we only found one relationship between MEHHP and income. In addition, a recent study by Zhu et al (2016) suggested that there was no significant association of any phthalate metabolite with maternal age, prepregnancy BMI and income. Regarding maternal factors, all DEHP metabolites were positively related to parity in our study, which was partly consistent with Zhu et al (2016).…”

“…In Chinese pregnant women from the HBC study, median concentrations of total MBP (53.0 ng/mL) were the highest, followed by secondary metabolites of di(2-ethylhexyl) phthalate (DEHP, including MEHHP (5.59 ng/mL) and MEOHP (4.70 ng/mL)), MEP (4.60 ng/mL) and MEHP (1.73 ng/mL) (Zhu et al, 2016). However, the characteristics of other cohorts (Kim et al, 2011;Lien et al, 2015;Polanska et al, 2014;Téllez-Rojo et al, 2013;Yolton et al, 2011)were different from ours.…”

“…In the mainland of China, limited studies have investigated urinary phthalate levels in this population. The Healthy Baby Cohort (HBC) study measured six phthalate metabolites in 293 urine samples from pregnant women at delivery (Zhu et al, 2016). Our previous Ma'anshan Birth Cohort (MABC) study analyzed seven phthalate metabolites in 3103 urine samples of pregnant women during early pregnancy (5-14 weeks gestation) (Gao et al, 2016).…”
