Associations of pre- and postnatal per- and polyfluoroalkyl substance exposure with adolescents' eating behaviors.

Background: Per- and polyfluoroalkyl substances (PFAS), persistent environmental chemicals, may act as obesogens by interacting with neuroendocrine pathways regulating energy homeostasis and satiety signals influencing adolescent eating behaviors.

Methods: In 211 HOME Study adolescents (Cincinnati, OH; recruited 2003-2006), we measured PFAS concentrations in serum collected during pregnancy, at delivery, and at ages 3, 8, and 12 years. Caregivers completed the Child Eating Behavior Questionnaire (CEBQ) at age 12, and we calculated food approach and food avoidance scores.

Evaluating Housing Characteristics Associated With Childhood Lead Exposure in Providence, Rhode Island.

Objective: This research aims to take an in-depth look into the child, housing, and neighborhood characteristics associated with Providence children's likelihood of having elevated blood lead levels (BLLs).

Design And Setting: The 2019 Providence, Rhode Island, Property Tax Assessor's database, containing each property owner's address, was geocoded and spatially joined with the 2017-2019 blood lead tests for children aged 0 to 6 years from the Rhode Island Department of Health.

Main Outcome Measures: The prevalence of elevated BLLs (≥5 μg/dL) overall, as well as by property type, number of properties owned, owner occupancy, assessed value, and neighborhood rates of old housing and poverty, was computed.
