Although acute pesticide poisoning (APP) is known to be a major health concern among farmers in developing countries, knowledge of its prevalence and risk factors is limited. The purpose of this study was to investigate the prevalence and a broad range of potential work-related risk factors of APP among Iranian farmers and farm workers. This cross-sectional study was conducted in rural areas of the Twiserkan County in Iran. In this study, there were 474 farmers and farm workers who had used pesticide 1 week before data collection. Participants were selected from 104 villages. Data were gathered using a questionnaire and analyzed using STATA (version 14.2 SE). Binary logistic regression and multinomial logistic regression were employed. The results of this study showed that 286 (60.3%) farmers and farm workers who applied pesticides suffered from work-related APP. Most frequent APP symptoms were runny nose (29.8%) and headache (25.1%). Five risk factors were identified, including annual income ( p < 0.05), number of farming years (odds ratio (OR) = 0.31), number of spraying years (OR = 2.40), place of pesticide storage (OR = 2.69), and type of sprayer ( p < 0.05). The results of this study indicated that APP is prevalent among the studied farmers. Some work-related factors play an important role in APP among Iranian rural farmers. In addition, the magnitude of these risk factors differed significantly by severity of acute and somatic pesticide poisoning.
