• Youth ATV operators typically have a diminished field of vision compared to adults. • Limited vision in youth compromises control and perception, increasing crash risks. • Findings provide data to update ATV safety guidelines and prevention strategies. Problem: All-Terrain Vehicles (ATVs) cause a distressing number of fatalities and injuries among farm youth in the United States. The number of severe injuries caused by ATV crashes on farms, which stood at 25 children in 2019, is expected to rise due to increased ATV sales during the COVID-19 pandemic. Existing research into children's injuries has explored physical capabilities like anthropometry, strength, and visual acuity. Yet, studies assessing youths' physical ability to operate ATVs remain limited. This study tests the hypothesis that diminished vision field in young ATV operators raises crash risks. Methods: This study used SAMMIECAD digital human modeling system to simulate and compare the field of vision of youth and adult ATV operators. The simulations incorporated 3-D mockups of ATVs, humans, sprayer tanks, windshields, and obstacles. Ten utility ATVs and children of both genders across nine ages (8–16) and three height percentiles (5th, 50th, 95th) were evaluated. Results: Simulations showed that young ATV operators generally have a more restricted field of vision than adults, particularly those aged 6–11 years. Discussion: Visual limitations hinder riders' ability to see ATV controls, potentially leading to vehicle control loss. Moreover, they impair environmental perception during riding, compromising youths' ATV operation abilities and increasing crash risks. Practical Applications: These findings offer crucial data in support of modifying ATV safety guidelines. Additionally, they can guide youth occupational health professionals in preventing ATV-related incidents in agricultural settings. [ABSTRACT FROM AUTHOR]

Objective: The aim of this study was to introduce and evaluate two interventions, Ergo Bucket Carrier (EBC) and Easy Lift (EL), for youths (and adults) to handle water/feed buckets on farms.Background: The physical activities of both adult and youth farm workers contribute to the development of low-back disorders (LBDs). Many of the activities youths perform on farms are associated with increased LBD risk, particularly, the handling of water and feed buckets.Method: Seventeen adult and youth participants (10 males and seven females) participated in this study. To assess the risk of LBDs, the participants were instrumented with a three-dimensional spinal electrogonio-meter while lifting, carrying, and dumping water buckets using the traditional method and the two interventions.Results: For both the adult and youth groups, the results showed that the two interventions significantly decrease the magnitudes of LBD risk in many of the tasks evaluated. Overall, the use of the EBC resulted in a 41% reduction in the level of LBD risk for the carrying task and a reduction of 69% for the dumping task. Using the EL, on the other hand, is especially effective for lifting tasks (55% reduction in LBD risk). Results of the subjective response were consistent with the objective evaluations.Conclusion: This study demonstrated the potential for ergonomic interventions in reducing LBD risk during the common farming task of bucket handling.Application: Potential application of this study includes the introduction of the EBC and EL in family farms to reduce the LBD risk among youth and adult farmers.
