The study found that chronic exposure to insecticides and organophosphorus pesticides may be associated with a higher prevalence of overweight in farmers, but not necessarily with abdominal obesity. Additional research is needed to confirm these findings and clarify the specific mechanisms of these pollutants in the etiology of obesity.
The association of chronic exposure to pesticides with overweight and abdominal obesity in adult farmers was investigated. This cross-sectional study included a random sample of 122 farmers and their family members of both sexes (61% were male), living in the municipality of Farroupilha, southern Brazil. Pesticide groups and their individual compounds were self-reported and classified according to major functional and chemical classes (never used, 1-20 years, or > 20 years of use). Abdominal obesity and overweight were the outcomes of interest. A multivariate Poisson regression model was analyzed. After confounding factors were controlled, chronic use (>20 years) of insecticides (PR: 1.45; 95% CI: 1.00-2.10) and organophosphorus pesticides (PR: 1.48, 95% CI: 1.02-2.12) was associated with a higher prevalence of overweight but not abdominal obesity. Additional studies are needed to confirm our findings and clarify the specific mechanisms of these pollutants in the etiology of obesity.
