Mixed-Methods Assessment Of Farmworkers’ Perceptions Of Workplace Compliance With Worker Protection Standards And Implications For Risk Perceptions And Protective Behaviors, Carly Hyland, Lisa Meierotto, Rebecca L. Som Castellano, Cynthia L. Curl

Public Health and Population Science Faculty Publications and Presentations

Introduction: The Environmental Protection Agency (EPA)’s Worker Protection Standards is the primary set of legislation aimed at protecting farmworkers from occupational pesticide exposure in the United States. Previous studies suggest that worker adoption of Pesticide Protective Behaviors (PPBs) promoted by WPS is associated with lower urinary pesticide concentrations. However, adoption of PPBs is often outside of the control of individual farmworkers and dependent on workplace factors such as employer provisioning of Personal Protective Equipment (PPE) and access to trainings/resources.

Methods: We conducted a mixed-method study including urinary pesticide biomonitoring, surveys, and interviews with 62 Latinx farmworkers in southwestern Idaho from …

Examination Of Urinary Pesticide Concentrations, Protective Behaviors, And Risk Perceptions Among Latino And Latina Farmworkers In Southwestern Idaho, Carly Hyland, Alejandra Hernandez, Éric Gaudreau, Jessica Larose, Jean-François Bienvenu, Lisa Meierotto, Rebecca L. Som Castellano, Cynthia L. Curl

Public Health and Population Science Faculty Publications and Presentations

Introduction: Studies have documented high levels of pesticide exposure among men farmworkers; however, few have examined exposures or the experiences of women farmworkers. Data gaps also exist regarding farmworkers’ perceived risk and control related to pesticides, information that is critical to develop protective interventions.

Objective: We aimed to compare urinary pesticide biomarker concentrations between Latino and Latina farmworkers and examine associations with occupational characteristics, risk perceptions, perceived control, and protective behaviors.

Methods: We enrolled a convenience sample of 62 farmworkers (30 men and 32 women) during the pesticide spray season from April–July 2022 in southwestern Idaho. Participants were asked to …

Perspective: Organic Food Consumption During Pregnancy And The Potential Effects On Maternal And Offspring Health, Cynthia L. Curl, Annica Balentine

Public Health and Population Science Faculty Publications and Presentations

Pregnancy represents a critical window for both maternal and child health. Previous studies have shown that the consumption of an organic diet during pregnancy can reduce pesticide exposure compared with the consumption of a conventional diet. It is possible that this could, in turn, improve pregnancy outcomes, because maternal pesticide exposure during pregnancy has been associated with increased risk of pregnancy complications. Organic foods are produced by methods that comply with organic standards, generally restricting the use of agrochemicals, such as synthetic pesticides. In the past few decades, the global demand for organic foods has increased drastically, driven in large …

Interactions Of Agricultural Pesticide Use Near Home During Pregnancy And Adverse Childhood Experiences On Adolescent Neurobehavioral Development In The Chamacos Study, Carly Hyland

Public Health and Population Science Faculty Publications and Presentations

Background: Studies have documented independent adverse associations between prenatal and early-life exposure to environmental chemicals and social adversity with child neurodevelopment; however, few have considered these exposures jointly. The objective of this analysis is to examine whether associations of pesticide mixtures and adolescent neurobehavioral development are modified by early-life adversity in the Center for the Health Assessment of Mothers and Children of Salinas (CHAMACOS) cohort.

Methods: We used linear mixed effects Bayesian Hierarchical Models (BHM) to examine the joint effect of applications of 11 agricultural pesticides within 1 km of maternal homes during pregnancy and youth-reported Adverse Childhood Experiences (ACEs) …

Measurement Of Urinary Pesticide Biomarkers Among Latina Farmworkers In Southwestern Idaho, Cynthia L. Curl, Lisa Meierotto, Rebecca L. Som Castellano, Meredith R. Spivak, Kurunthachalam Kannan

Public Health and Population Science Faculty Publications and Presentations

Background Women who work in agriculture may have greater risk of pesticide exposure than men who share this occupation. Despite an increase in the fraction of the agricultural workforce comprised by women, few studies have characterized pesticide exposure in the USA with a focus on among these workers.

Objective This pilot study aimed to describe pesticide exposure in a cohort of Latina farmworkers in farming communities in southwestern Idaho.

Methods We collected urine samples from 29 Latina farmworkers, which were analyzed for 11 pesticide biomarkers. We evaluated the effect of pesticide spray season on urinary biomarker levels, and explored the …

Organophosphate Pesticide Dose Estimation From Spot And 24-Hr Urine Samples Collected From Children In An Agricultural Community, Carly Hyland, Katherine Kogut, Robert B. Gunier, Rosemary Castorina, Cynthia Curl, Brenda Eskenazi, Asa Bradman

Public Health and Population Science Faculty Publications and Presentations

Background: Spot urine samples are often used to assess exposure to organophosphate (OP) pesticides in place of “gold standard” 24-hr samples, which are cumbersome to collect. Assessment of non-persistent chemicals using spot urine samples may result in exposure misclassification that could bias epidemiological analyses towards the null. Few studies have examined the validity of measurements of urinary metabolites in spot samples to estimate daily OP dose or the potential implications of reliance on spot samples for risk assessments.

Objective: Examine the validity of using first morning void (FMV) and random non-FMV urine samples to estimate cumulative 24-hr OP pesticide dose …

Understanding Challenges To Well-Being Among Latina Farmworkers In Rural Idaho Using In An Interdisciplinary, Mixed-Methods Approach, Cynthia L. Curl, Lisa Meierotto, Rebecca L. Som Castellano

Public Health and Population Science Faculty Publications and Presentations

The aim of this study was to identify social, cultural and workplace-related risk factors affecting well-being among Latina farmworkers in rural Idaho. We recruited 70 Latina farmworkers from southwestern Idaho in 2019. We employed an inter-disciplinary, mixed-methods approach—including surveys, focus groups, interviews, and pesticide biomonitoring—to characterize multiple domains that influence well-being, including food security and access, housing conditions, social supports, access to medical care, and workplace safety. Six major themes emerged as primary challenges to Latina farmworkers’ well-being. In the public sphere, study participants identified these challenges as long working hours, concerns regarding pesticide exposure, and lack of enforcement of …

Organic Food Health Benefits Have Been Hard To Assess, But That Could Change, Cynthia Curl

Public Health and Population Science Faculty Publications and Presentations

“Organic” is more than just a passing fad. Organic food sales totaled a record US$45.2 billion in 2017, making it one of the fastest-growing segments of American agriculture. While a small number of studies have shown associations between organic food consumption and decreased incidence of disease, no studies to date have been designed to answer the question of whether organic food consumption causes an improvement in health.

I’m an environmental health scientist who has spent over 20 years studying pesticide exposures in human populations. Last month, my research group published a small study that I believe suggests a path forward …
