Pesticide Use and Health Effects among Nepalese Farmers: A Cross-Sectional Study in Tokha Municipality.

Background: Pesticides are essential for agricultural development, but their increased use in developing countries like Nepal poses health risks to farmers. Methods: A cross-sectional study was conducted in wards 1, 2, and 3 of the Tokha Municipality in Kathmandu District to identify the health effects of pesticides and associated factors among farmers. The study included 333 respondents who were interviewed between April 26 and June 04, 2022. Results: The majority of farmers (36.6%) were aged between 40 and 49 years, with a median (IQR) age of 45.0 (38.0 to 51.0) years. All farmers reported using pesticides, with 100% usage in vegetables. Most respondents (73%) reported experiencing health effects: headache (69.5%), skin irritation (42.8%), and burning eyes (31.3%) were the most common symptoms. Only 8% sought medical care. Additionally, 94.6% of respondents had not received training on integrated pest management, and none of them reported using a complete set of personal protective equipment. The study found that older age groups, females, those who were unable to read and write, and those of the Hindu religion, as well as respondents with longer pesticide use, more frequent spraying, and not detecting wind direction, had significantly higher odds of self-reported health problems ( Conclusion: Our findings show that all farmers in the study were using pesticides, and the majority had reported health effects. Therefore, we recommend that farmers receive training on integrated pest management, use a complete set of personal protective equipment, and promptly seek medical care if they experience health issues.
