Recruitment of Row Crop Farmers into a Research Study to Assess Farm Hazards.

Farmers are at an elevated risk for injuries and are, therefore, highly sought after for research studies. However, their participation in research studies is low. We examine how characteristics of the farmer, farm location, and timing of recruitment contact impact the probability that farmers will engage and participate in a study of injuries and related farm hazards. Study data were obtained from the Farm Safety Study conducted at the University of Iowa between June 2019 and March 2020. We used recruitment data from participants enrolled using Farm Journal magazine subscription lists. Multinomial logistic regression was used for predictive modeling. Predictor variables included the time of day and the farm season in which phone contact for study recruitment was attempted, as well as the rurality of the farm. Two models were created to characterize screening and participation of farmers in the study. Farm season and time of day of the last recruitment call increased the likelihood of farmers being screened for study participation and completing the study. Specifically, contacting farmers during the growing season and during the daytime, regardless of farm rurality, resulted in higher probabilities of participation. Studies of agricultural injury may be more efficiently conducted, with higher participation responses, when circumstances of the recruitment call are considered. This work serves as a starting place for much-needed methodological research to identify factors that increase participation of farmers and farm workers in research studies.

Circumstances Contributing to Installation, Maintenance, and Repair Worker Death by Suicide.

OBJECTIVE: To examine risk factors related to death by suicide among installation, maintenance, and repair (IMR) workers compared with workers in other occupational groups. METHODS: The National Violent Death Reporting System (NVDRS) data for the years 2013 to 2018 was used to identify suicide deaths. Circumstance variables were used to examine differences between IMR workers and other workers. RESULTS: Having a physical health problem (1.13; 95% confidence interval [CI], 1.03 to 1.23) or a diagnosis of posttraumatic stress disorder (1.24; 95% CI, 1.03 to 1.50) was more likely to contribute to IMR worker suicide compared with other occupations. Installation, maintenance, and repair workers were less likely to receive treatment for a mental health diagnosis or substance use disorder (0.88; 95% CI, 0.81 to 0.94). CONCLUSIONS: Additional support for physical health problems, posttraumatic stress disorder diagnoses, and mental health care access among IMR workers may reduce suicide deaths.

Prevalence of neonicotinoid insecticides in paired private-well tap water and human urine samples in a region of intense agriculture overlying vulnerable aquifers in eastern Iowa.

A pilot study among farming households in eastern Iowa was conducted to assess human exposure to neonicotinoids (NEOs). The study was in a region with intense crop and livestock production and where groundwater is vulnerable to surface-applied contaminants. In addition to paired outdoor (hydrant) water and indoor (tap) water samples from private wells, urine samples were collected from 47 adult male pesticide applicators along with the completions of dietary and occupational surveys. Estimated Daily Intake (EDI) were then calculated to examine exposures for different aged family members. NEOs were detected in 53% of outdoor and 55% of indoor samples, with two or more NEOs in 13% of samples. Clothianidin was the most frequently detected NEO in water samples. Human exposure was ubiquitous in urine samples. A median of 10 different NEOs and/or metabolites were detected in urine, with clothianidin, nitenpyram, thiamethoxam, 6-chloronicotinic acid, and thiacloprid amide detected in every urine samples analyzed. Dinotefuran, imidaclothiz, acetamiprid-N-desmethyl, and N-desmethyl thiamethoxam were found in ≥70% of urine samples. Observed water intake for study participants and EDIs were below the chronic reference doses (CRfD) and acceptable daily intake (ADI) standards for all NEOs indicating minimal risk from ingestion of tap water. The study results indicate that while the consumption of private well tap water provides a human exposure pathway, the companion urine results provide evidence that diet and/or other exposure pathways (e.g., occupational, house dust) may contribute to exposure more than water contamination. Further biomonitoring research is needed to better understand the scale of human exposure from different sources.

Safety Measures, Pesticide Concerns and Resources Utilized among Young Adult Workers: A Brief Report.

INTRODUCTION: Resources on pesticide information are widely available; however, little is known about the concerns young agricultural workers have about pesticides, whether they use existing resources to find information about pesticides, and how these resources influence safety behaviors such as personal protective equipment (PPE) use. OBJECTIVES: To examine demographic characteristics, safety measures, concerns about pesticide use and resources for pesticide information. METHODS: Young agricultural workers were recruited through three collegiate agricultural programs and completed an online questionnaire related to pesticide safety and use. RESULTS: Most participants who applied pesticides reported always wearing gloves (60.5%), using a tractor with an enclosed cab (68.4%), and always wearing long pants (76.3%). Among all participants, pesticide drift to crops (65.1%) and water contamination (62.3%) were the biggest concerns among young agricultural workers. The internet was the most utilized source to locate information about pesticides (76.4%), with the most common internet resources being online materials from universities or colleges (71.6%), the government (69.1%), or pesticide companies (66.7%). Accessibility (90.6%) and speed (78.3%) were the most common reasons for using the internet for information. Misinformation was the most common barrier (80.2%). CONCLUSIONS: Future studies should examine the accuracy and accessibility of pesticide information available on the internet since young adult workers rely on these resources for pesticide information.

Development of a Checklist to Identify Injury Hazards on Row Crop Farms in the Midwestern United States.

Agriculture is among the most dangerous industries in the U.S., yet routine surveillance of injury hazards is not currently being conducted on a national level. The objectives of this study were to describe a new tool, called the Hazard Assessment Checklist (HAC), to identify and characterize farm hazards that increase injury risk to farmers and farm workers, and (2) report the inter-rater reliability of the new tool when administered on row-crop farms in Iowa. Based on a literature review and a consensus of expert opinion, the HAC included hazards related to self-propelled vehicles, powered portable implements, fixed machinery and equipment, farm buildings and structures, fall risks, and portable equipment associated with fall risk. A scoring metric indicating the extent of compliance with recommended safety guidelines and standards was developed for each item of the HAC, which included compliant, minimal improvement needed, substantial improvement needed, and not compliant. Inter-rater reliability was assessed from data collected by research staff on 52 row crop farms in Iowa. Cohen's weighted Kappa values demonstrated high inter-rater reliability, ranging between 0.86 and 0.94, for all HAC sections. The HAC can be completed in 1.5-2 hours on each farm and requires about three hours of training, two hours of which are spent in field training. The ability to monitor injury-related hazards over time using an empirically driven tool will contribute significantly to injury prevention efforts in an industry with consistently high rates of fatal and nonfatal injury.
