Pesticide exposure among students and their families in Nova Friburgo, Rio de Janeiro

Farming is a risky occupation, especially family farming in developing country. The occupational hazards commonly used in such activity could affect all family members, including children and adolescents. This study describes the pattern of pesticide exposure among students and their families from a farming region located in Nova Friburgo, State of Rio de Janeiro, Brazil. Sociodemographic characteristics, habits, working practices and the degree of exposure to pesticides were assessed by a questionnaire. Our study population consisted of students and family members of both sexes, aged between 6 and 85 years old (N = 352) being 167 women and 185 men. There was a predominance of participants between 10-19 years (71.3%), singles (77.5%), and most had not completed primary education (54.5%). In terms of occupation, 45.5% reported to be farmers and 39.6% were students. The variables mostly associated with pesticide exposure were sex (p < 0.001), educational level (p < 0.001), and being a farmer (p < 0.001). Our results showed that children and teenagers seemed to have the same degree of exposure to pesticides as the adults. Our findings also suggest that sex, occupation and educational level, despite teachers were included, are directly associated with degree of exposure.
