Participant perspectives related to individual chemical exposure report-back approaches in three environmental health studies.

Returning results to participants of environmental exposure studies has become more common in recent years. Despite evidence of benefits for study participants, there are challenges in communicating results to people with limited resources or capacity to mitigate chemical exposures. We interviewed N=54 participants and compared exposure report-back conducted in 2010-2013 across three susceptible study populations: 1) low-income pregnant individuals in the Chemicals in Our Bodies (CIOB) study; 2) the Center for the Health Assessment of Mothers and Children of Salinas (CHAMACOS) cohort; and 3) early childhood educators (ECE).

Fast-food consumption and asthma-related emergency room visits in California.

Introduction: Asthma is common, affecting up to 8% of adults in the United States. Several studies have shown an association between poorer diet and asthma. Despite the prevalence of fast-food consumption in the Western diet, research examining fast food consumption and asthma is limited.

Estimated human intake of endogenous and exogenous hormones from beef in the United States.

Background: Endogenous and exogenous hormones may be present in beef. Human consumption of hormones has been linked to adverse health effects.

Objective: To estimate daily intake of hormonal growth promotants (HGP) from beef consumed by the US population.

Prenatal Maternal Occupation and Child Epigenetic Age Acceleration in an Agricultural Region: NIMHD Social Epigenomics Program.

Importance: Research on fetal epigenetic programming suggests that the intrauterine environment can have long-term effects on offspring disease susceptibility.

Objective: To examine the association between prenatal maternal occupation and child epigenetic age acceleration (EAA) among a farmworker community.

Design, Setting, And Participants: This cohort study included participants in the Center for the Health Assessment of Mothers and Children of Salinas, a prospective, Latino, prebirth cohort.

Childhood exposure to organophosphate pesticides: Functional connectivity and working memory in adolescents.

Background: Early life exposure to organophosphate (OP) pesticides is linked with adverse neurodevelopment and brain function in children. However, we have limited knowledge of how these exposures affect functional connectivity, a measure of interaction between brain regions. To address this gap, we examined the association between early life OP pesticide exposure and functional connectivity in adolescents.
