Bisphenol Exposure, Phthalate Exposure
Conditions
Brief summary
Phthalates and bisphenols have been detected in a range of infant care products. This pilot study will test whether intervening on these sources of exposure during the critical period of minipuberty affects infants' body burden of phthalates and bisphenols. Investigators will recruit 10 participants from the ongoing NYU Children's Health and Development Study (CHES) cohort study who are \>=37 weeks gestation, carrying a male fetus, and intending to breastfeed. Investigators will randomly assign them to use either conventional baby products or phthalate- and bisphenol-free baby products for the first three months of their children's lives. Toward the end of the intervention, investigators will collect maternal breast milk and infant urine, and assay samples for phthalate metabolite and bisphenol concentrations.

Primary
| Measure | Time frame | Description |
|---|---|---|
| Log Signal Intensity of Bisphenol A (BPA) in Child Urine Samples | Month 3 | Child urine samples were analyzed for bisphenols and for phthalate metabolites via non-targeted HPLC-MS/MS. The log signal intensity, an arbitrary unit, is a measurement of the signal strength of BPA in child urine; as the concentration of BPA increases, the signal intensity increases proportionally in a logarithmic fashion; higher values indicate greater infant exposure to bisphenol. |
| Log Signal Intensity of Bisphenol A (BPA) in Maternal Urine Samples | Month 3 | Maternal urine samples were analyzed for bisphenols and for phthalate metabolites via non-targeted HPLC-MS/MS. The log signal intensity, an arbitrary unit, is a measurement of the signal strength of BPA in child urine; as the concentration of BPA increases, the signal intensity increases proportionally in a logarithmic fashion; higher values indicate greater maternal exposure to bisphenol. |

Pre-assignment details
Infants were not considered enrolled participants for the purpose of this study; infant urine samples were submitted voluntarily by enrolled (mother) participants at home during follow-up. Participant information (participant flow, baseline characteristics) are thus not reported for infants.
