摘要：We evaluated a community-based participatory research worksite intervention intended to improve farmworkers' behaviors at work and after work to reduce occupational and take-home pesticide exposures. The workers received warm water and soap for hand washing, gloves, coveralls, and education. Self-reported assessments before and after the intervention revealed that glove use, wearing clean work clothes, and hand washing at the midday break and before going home improved significantly. Some behaviors, such as hand washing before eating and many targeted after-work behaviors, did not improve, indicating a need for additional intervention. Agricultural pesticide exposure among farmworkers is a long-standing occupational health and environmental justice concern. 1 – 3 The importance of preventing farmworkers' pesticide exposures is underscored by research documenting exposures to farmworkers' children from agricultural pesticide residues brought home by parents 4 – 11 and potential adverse neurodevelopmental effects. 12 – 14 Although effectively preventing pesticide exposures at work is paramount for safeguarding the health of farmworkers and their families, few comprehensive worksite programs, including the Environmental Protection Agency's Worker Protection Standard, 15 have been evaluated. 16 We conducted a cluster-randomized, controlled trial of a community-based participatory research (CBPR) worksite intervention to reduce farmworkers' occupational and take-home pesticide exposures. To our knowledge, this was the first evaluated worksite intervention that integrated behavioral and environmental components and provision of protective clothing. Here we report the intervention's effect on farmworkers' behaviors; impact on exposure was reported previously. 17
