Predictors of pesticide poisoning.

The analysis of 1,026 reports of suspected pesticide poisonings to the regional Poison Control Centre at the Hospital for Sick Children, Toronto consisted of 597 (58.2%) cases less than six years of age. Age was the strongest predictor: there was a risk of 3.1 that young children would encounter rodenticide poisoning compared to that of insecticides; a ten-fold risk of having symptoms from pesticide poisoning if the victim was over five years of age; an increased risk of 5.9 of exposure to moderate or large amounts of pesticide, compared to small quantities, for those over five years of age; and there was less treatment referral for young children, and a 5.7 risk of being referred if the victim was over the age of five years. Other significant predictor variables include the type of person making the inquiry (lay or physician/nurse), the calendar season of the event, and the location (metropolitan or nonmetropolitan) of the event.
