Objectives: The relationship between heat stress, chronic kidney diseases and acute kidney injury has been documented in cross-sectional studies with agricultural workers. However, only a few international studies have assessed renal function in agricultural workers longitudinally. Our research study, Occupational Heat Exposure and Renal Dysfunction (OHEaRD) is the first longitudinal study in the U.S. that monitored renal function in agricultural workers five times over the course of 32-months. The main objectives of this study were to evaluate the rate of retention and identify predictors associated with retention in a longitudinal study with agricultural workers.

Methods: In January 2020, we enrolled 119 Florida agricultural workers to observe on 5 workdays over 32 months. Retention was defined by the number of follow-up visits that a participant attended, the consistency of visit attendance, and attendance at the last visit. Participants were provided hemoglobin A1C, lipid panel, creatinine measurement, glomerular filtration rate (eGFR), blood pressure, and body mass index results and an incentive gift card were handed out to participants at each visit.

Results: Four enrollees did not participate on any workday, thus analysis concentrated on the remaining 115 participants. The majority of participants (64%) completed the 32-month study, 78% completed at least 4 visits, and 55% completed all 5 visits. The statistically significant predictors of higher retention among this study were being older in age (p=0.02), Mexican nationality (p=0.004), working in ferneries (p=0.009), more years working in agriculture (p=0.02), and higher total cholesterol (p=0.02). Appreciation for the health tests was associated with greater participation at the final visit (p=0.01).

Conclusion: Retention in longitudinal studies is crucial to better understand kidney disease among agricultural workers, an understudied population. Participants reported valuing the access to health results, indicating that implementing point-of-care health screenings and providing the health results to each participant is a good retention strategy. There was some evidence that a participant living with or being related to a fellow co-participant could impact retention as they either showed up or missed visits together, suggesting recruiting from the same household may reduce retention.

Objectives: The "decision" to go to work, or remain absent, when unwell undermines worker energy. I is therefore understandable that low work performance is one of the main consequences of the act of presenteeism. This study evaluated the association between presenteeism, and absolute and relative work performance among fruit farm workers in Northeast Brazil.

Methods: A cross-sectional study investigated 340 paid employees of both sexes, aged 18 years or over, who worked during the 2019 irrigated fruit harvest in the municipality of Petrolina, Northeast Brazil. Absolute and relative work performance were measured using the Health and Work Performance Questionnaire. Workers who answered "one or more days" to the question "How many days have you worked this season when you were injured or unwell?" were considered presenteeists. Poisson regression with robust variance models was used to estimate the prevalence ratios of the main associations, adjusted for potential confounders.

Results: Presenteeist workers presented lower absolute and relative work performance than non-presenteeist workers according to the strata for most of the investigated factors. The associations between presenteeism, and absolute (adjusted prevalence ratio = 1.31) and relative work performance (adjusted prevalence ratio = 1.45) remained strong, even after multiple adjustments for other relevant variables.

Conclusion: Presenteeist fruit culture workers self-assessed their work performance as lower than non-presenteeist ones.

Objective: Agricultural producers face a wide array of stress triggers, shocks, and long-term pressures such as drought, flooding, fire, government policies, financial insecurity, and physical injuries. Extant research has revealed that mental health stigma, lack of access to care in rural areas, and negative coping responses (alcohol abuse, suicide, prescription drugs use) exacerbate the challenge of producer responses to short and long-term adversity. Resilience, the traits, processes, and capacities of producers to adapt and transform their approach to farming or ranching, when necessary, in response to stress triggers or long-term pressures, has received less research attention, particularly in the Western United States. The purpose of the study was to apply an interactionist occupational resilience theoretical perspective to the investigation of contextual factors contributing to resilience in Western United States agricultural producers.

Methods: Qualitative interviews (45 to 90 minutes) were conducted with agricultural producers (n=51) from Western states and territories. Applied thematic analysis with a phenomenological lens was utilized to analyze interview transcriptions. First and second level coding were conducted to derive themes.

Results: The analysis revealed that resilience is based upon the interactions between traits of producers and the context of agriculture. Four themes were generated (Agricultural Life, External Stressors, Traits and Adaptations, and Supports and Resources), supported by subthemes. The themes and subthemes are depicted in an agricultural producer resiliency model. The findings shed light on the equivocal role of neighbors in providing support for each other and the double-edged sword of co-working with family.

Conclusions: The findings underscore that social capital is an important mechanism for supporting farmers and ranchers, as those with stronger social resources are more resilient. We recommend more funding to tailor stress and mental health programming to the specifics of agriculture, integration of behavioral health in primary care as a mechanism to increase access to care, and more intentional technical assistance for farmers and ranchers on strategic planning and problem solving.

Objectives: Children of seasonal agricultural workers (SAW) live in the worst conditions of agricultural labor and, consequently, face many health risks. Therefore, it is essential to evaluate the quality of life (QoL) of these children. This study aimed to compare the QoL between children of SAW and local residents in semi-rural areas of Eskisehir, Turkey, and determine the factors affecting them.

Methods: In this cross-sectional study, we included children of SAW living in temporary camp areas and those of local residents visiting the Family Health Center close to the camp areas. Basic sociodemographic data collection forms and the Pediatric Quality of Life (PedsQL) scale were employed for data collection. Univariate and multivariate analyses were used to determine factors that had a significant effect on the QoL.

Results: We included 324 children of SAW and 256 local children. As per the multivariate analysis, QoL was lower in children aged between 8 and 12 years, with physician-diagnosed chronic diseases, and children of SAW. Also, there was no significant association between gender, parental education levels, family income, number of siblings, school attendance status, and QoL level.

Conclusion: The QoL of children of SAW families was significantly lower than their peer local children. Therefore, the appropriate authorities must prioritize the planning and implementation of health services for SAW families.

Gastrointestinal (GI) disorders are a major public health burden in the United States. Due to close contact with animals, farmers may be a high risk subgroup for acute GI infections, though some studies suggest farm work is actually protective against GI illness. The purpose of this study was to examine associations between dairy farm work and GI symptoms over 3 years. A prospective, matched cohort study was used that included 70 adult dairy farm workers and 74 matched (age, gender, ZIP code) non-farm participants from central Wisconsin. The outcome was mean GI symptom scores for abdominal pain, diarrhea, constipation, dyspepsia, nausea, and reflux, per the 23-item Gastrointestinal Symptoms Severity Index (GISSI). After adjustment for potential confounding variables, linear regression results indicated dairy farm workers had significantly lower GISSI scores for abdominal pain (mean±SE = 4.3 ± 1.1 dairy vs. 7.6 ± 1.1 non-farm, p = .047), diarrhea (3.2 ± 1.0 dairy vs. 7.0 ± 1.0 non-farm, p = .010), constipation (2.0 ± 0.8 dairy vs. 6.6 ± 0.8 non-farm, p < .001), and dyspepsia (2.0 ± 0.6 dairy vs. 3.9 ± 0.5 non-farm, p = .026). Working on a dairy farm was associated with significantly less frequent and severe GI illness symptoms in adults. Future research should identify underlying causal pathways, including possible farm animal exposures, that influence beneficial gut microbiota that could inform therapeutic remedies to help prevent clinical GI disorders.

Objective: Pesticide exposure via take-home pathways is a major health concern among farmers. However, little is known about the effects of pesticide take-home pathways on small-scale Hmong farmers in the Central Valley. This study explored factors that contribute to pesticide exposure via the take-home pathway among small-scale Hmong farmers in the Central Valley.

Methods: Detailed ethnographic observations of small-scale farms and corresponding homes were coupled with in-depth qualitative interviews with Hmong farmers to assess the extent of the pesticide take-home pathway.

Results: The study found daily challenges and numerous ways that pesticide particles may be introduced into farmers' homes. Given the paucity of research about Hmong farmers' pesticide take-home pathways, the study's findings advance the scholarship on pesticide exposures in the Hmong farmer community.

Conclusion: This study advocates for more culturally and linguistically appropriate pesticide exposure training and educational programs tailored to Hmong farmers in the United States.

Objectives: The purpose of this study was to examine the association between farm exposures and asthma and allergic disease in children while also highlighting the experiences of non-farm rural children.

Methods: This was a cross-sectional analysis of data collected from across the province of Saskatchewan, Canada in 2014. Surveys were completed by parents of 2275 rural dwelling children (farm and non-farm) aged 0 to 17 years within 46 rural schools. Questionnaires were distributed through schools for parents to complete.

Results: Asthma prevalence was 7.6%, of which 29.5% of cases were allergic. After adjustment for potential confounders, home location (farm vs non-farm) and other farm exposures were not associated with asthma and asthma phenotypes. Those who completed farm safety education were more likely to have asthma (11.7% vs. 6.7%; p = .001) compared to children without asthma. In sub-analyses among 6-12-year-old children, boys were more likely to have asthma (non-allergic) and use short-acting beta-agonists compared to girls. Doing farm work in the summer was associated with an increased risk of asthma [adjusted OR (aOR) = 1.71 (1.02-2.88); p = .041]. Doing routine chores with large animals was associated with an increased risk of asthma [aOR = 1.83 (1.07-3.15); p = .027] and allergic asthma [aOR = 2.37 (95%CI = 1.04-5.40); p = .04].

Conclusion: The present study showed that the prevalence of asthma and asthma phenotypes were similar between farm and non-farm rural children. There did not appear to be differential involvement in farming activities between those with and without asthma although those with asthma had more training suggesting possible attempts to mitigate harm from farm exposures.

Objectives: To identify current knowledge about the role of fatigue in occupational injury in the agricultural sector and briefly assess potential intervention approaches.

Methods: Narrative review of peer reviewed literature (in English) from 2010 to 2022 focusing on fatigue in agricultural and other sectors. Data were extracted from Medline, Scopus, and Google Scholar.

Results: The initial search revealed 6,031 papers, of these 33 met the inclusion criteria. The literature unanimously agreed that fatigue contributes to occupational injury in agriculture and related industries. However, there was a scarcity of literature specific to Australia or agriculture. This limits the ability to draw conclusions about the true relationship between fatigue and injury.

Conclusion: While fatigue is likely a major contributor to occupational injury in Australian agriculture, the limited literature impedes the ability to draw conclusions and extrapolate interventions used by other industries that are practical and feasible, to agriculture. Future studies should establish the nature of the problem in Australian agriculture and consult with members of the sector to establish the best interventions to ameliorate the problem, then implement and robustly evaluate intervention studies.

Objective: The objective of this study was to investigate the effect of the size of pesticide pictograms on comprehensibility and their adherence to principles of familiarity, compatibility, and standardization. Pictograms usually involve complex details, and space limitation demands size reductions, which reduces overall comprehensibility, especially in agriculture and healthcare.

Methods: Two experiments were conducted. In experiment 1, the effect of different sizes of pictograms on comprehension was tested. In experiment 2, the level of compliance for different ergonomic principles on different sizes of pictograms was investigated.

Results: Results of experiment 1 indicated significant variation in comprehension level (p < .05), with maximum comprehension for the size 15 mm × 15 mm (87.6%) and minimum comprehension for the size 7 mm × 7 mm (69.4%). Results of experiment 2 indicated significant variation in compliance of ergonomic principles with different pictogram sizes (p < .05), with maximum compliance for the size 15 mm × 15 mm (7.7, 7.7, 7.6) and minimum compliance for the size 7 mm × 7 mm (6.3, 6.3, 6.3). A significant increase in the comprehensibility of pictograms and their adherence to familiarity, compatibility, and standardization was observed with the increase in the sizes of pictograms.

Conclusion: The smallest size of pictograms with a mean comprehension level ≥ 65% and scores for familiarity, compatibility, and standardization ≥ 7 (on a scale of 1 to 10) was 10 mm × 10 mm. The potential application of this research is to identify the most comprehensible size of pictograms that adhere to the principles of familiarity, compatibility, and standardization.

The objective of this pilot study was to determine the health needs of dairy farm workers and the feasibility of on-farm health risk screenings in the Texas Panhandle and South Plains. A cross-sectional study design was used to collect survey responses concerning health needs, occupational, and economic characteristics among 300 dairy workers between April 2020 and July 2021. Participants were predominantly immigrant Hispanic (88.8%) males (83.0%) of approximately 34.4 (SD 9.9) years of age, worked 6.0 (SD 0.4; Range 3-7) days a week and 9.9 (SD 1.5; Range 6-13) hours a day, earning a mean hourly rate of $13.40 (SD $2.80). Participants reported interest in attending on-farm health risk screenings (93.8%) as well as receiving a COVID-19 vaccine if it became available (86.4%). Health service categories were ranked from: (1st "most important") preventative care (Mean Rank 2.3), (2nd) laboratory and diagnostic care (Mean Rank 2.6), (3rd) nutritional and physical fitness support (Mean Rank 2.8), (4th) mental health care (Mean Rank 3.4), and (5th) workplace interventions (Mean Rank 3.6). Participants reported obtaining health information predominantly from internet searches (32.0%) and social media (17.7%). Findings suggest there is need and interest for on-farm health risk screenings and education among immigrant dairy workers in the Texas Panhandle-South Plains region. Addressing known barriers to health should be paramount to the organization of on-farm health risk screenings.
