Abstract

Respiratory problem is one of the main occupational health challenges faced by farmworkers, it can occur while preparing and applying pesticides and during tasks in recently sprayed fields. Symptoms associated with different respiratory problems include coughing, wheezing and airway inflammation are commonly observed among farmworkers who are occupationally exposed to pesticides. In low and middle-income countries, epidemiological evidence for the association between occupational exposure to pesticides and respiratory diseases in adults is limited. The study employed a cross-sectional survey that ran from January to February 2021 using face to face semi-structured questionnaire administered to farmworkers who were working on flower and coffee farms in Arusha and Kilimanjaro. Approximately 384 farmworkers were randomly selected to participate in this study. The study included organic and non-organic farmworkers who were directly engaged in agricultural activities and exclude supporting staff such as human resource managers who were not engaged directly in agricultural activities. The results indicate that non-organic farmers were at high risk of developing respiratory symptoms than organic farmworkers. Non-organic farmers were significantly associated with cough, rhinitis, and shortness of breath among farmworkers [adj. OR (95% CI) 31.94 (12.04, 84.70), 4.44 (2.61, 7.56) and 6.44 (1.98, 20.95)] respectively. However, there should be a systematic collection of data about poisoning cases occurring in the farm areas with a large number of employees so that effective measures can be taken to protect the farmers from chronic illnesses associated with pesticide exposure, particularly respiratory problems in this case.
