چکیده

Background: In rural areas of developing countries, children of agricultural workers have a high potential for exposure to organophosphorus (OP) pesticides. This puts them at an increased risk of damage to neurobehavioural performance, cognitive and psychomotor dysfunction. The main objective of this study was to assess the neurological risk of exposure to organophosphate pesticides in the children of agricultural workers in rural India. Methods: A community based cross-sectional study was carried out in 200 children aged 8-15 years in adjoining villages of Taluka Chalisgaon, district Jalgaon, Maharashtra. Various neurological symptoms like muscarinic (diarrhea, urinary incontinence, lacrimation, excessive salivation), nicotinic (tremors, muscle weakness, tachycardia) and general symptoms (headache, insomnia, numbness in legs, fatigue, anorexia, nausea, vomiting, dizziness, lethargy) were assessed by a specially designed Q16 questionnaire. Exposure index (EI) was calculated by multiplying the number of hours exposed to OP pesticides and the number of years of exposure. Results: The predominant clinical symptoms found in children in study group were muscarinic [diarrhea (12%), lacrimation (26%) and urinary incontinence (12%)]; nicotinic [muscle weakness (42%)] and general symptoms [pallor (58%), fatigue (34%), headache (30%), numbness in legs (24%), lethargy (20%)]. Also, the cognition and psychological function was more impaired in children exposed to OP pesticides than the non-exposed children. Conclusion: Our study findings suggest that neurologic symptoms involved both central and peripheral nervous systems, resulting from occupational and environmental exposure to OP pesticides. The high prevalence of neurologic symptoms could be attributed to chronic effects of OP pesticides on the central nervous system.
