Psychiatric disorders among Egyptian pesticide applicators and formulators.

Two hundred eight pesticide formulators, 172 pesticide applicators, and 223 control subjects (72 from an urban region matching the pesticide formulators and 151 from a rural area matching the pesticide applicators) underwent psychiatric assessment. The study aimed to screen for psychiatric morbidity using a standardized screening tool, the General Health Questionnaire, and a widely recognized system of diagnosis and classification, the revised third edition of the Diagnostic and Statistical Manual of Psychiatric Disorders (DSM-III-R). Significantly higher frequencies of psychiatric disorders were found in the exposed groups. The predominant diagnosis was depressive neurosis; the most frequent symptoms were irritability and erectile dysfunction. Theoretical and practical implications of these findings are discussed.
