Trial Outcomes & Findings for Phthalate and Bisphenol Exposure During Minipuberty (NCT NCT05864209)

NCT ID: NCT05864209

Last Updated: 2025-06-10

Results Overview

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.

Participant Flow

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.

Measure
Intervention Group
Half of the participants will be randomly assigned to the intervention group and will receive a three-month supply of phthalate- and bisphenol-free baby products (e.g., wipes, diaper cream) and a subscription to a cloth diaper service. Participants will be contacted after 2 and 6 weeks over the phone and administered a brief adherence survey. Phthalate- and Bisphenol-free Baby Products: 3-month supply. Products include wipes and diaper cream. Cloth Diapers: Subscription to cloth diaper service.
Control Group
Half of the participants will be randomly assigned to the control group and provided with a three-month supply of conventional disposable diapers (e.g., Huggies or Pampers) and baby products (e.g., wipes, diaper cream). Participants will be contacted after 2 and 6 weeks over the phone and administered a brief adherence survey. Conventional Disposable Diapers: 3-month supply. Conventional Baby Products: Products include wipes and diaper cream.

Half of the participants will be randomly assigned to the intervention group and will receive a three-month supply of phthalate- and bisphenol-free baby products (e.g., wipes, diaper cream) and a subscription to a cloth diaper service. Participants will be contacted after 2 and 6 weeks over the phone and administered a brief adherence survey. Phthalate- and Bisphenol-free Baby Products: 3-month supply. Products include wipes and diaper cream. Cloth Diapers: Subscription to cloth diaper service.
Control Group
n=2 Participants
Half of the participants will be randomly assigned to the control group and provided with a three-month supply of conventional disposable diapers (e.g., Huggies or Pampers) and baby products (e.g., wipes, diaper cream). Participants will be contacted after 2 and 6 weeks over the phone and administered a brief adherence survey. Conventional Disposable Diapers: 3-month supply. Conventional Baby Products: Products include wipes and diaper cream.
