Reducing occupational exposure to pesticides: understanding the preventive behaviours of French farmers.

OBJECTIVE

Preventing farmers' exposure to pesticides is a major public health issue. However, research on farmers' practices, particularly in high-income countries, rarely explores the combined role of sociodemographic, occupational and psychosocial factors or considers behaviours beyond the use of personal protective equipment. This study investigated pesticide risk prevention behaviours among French farmers, focusing on agricultural specialisation (ie, the main production on the farm), individual characteristics and key psychosocial determinants.

METHODS

A comprehensive telephone survey conducted among French winegrowers or grower-breeders probed their pesticide knowledge, psychological constructs (attitudes and perceptions, social norms and control) and individual and occupational factors. Associations with three preventive behaviours were studied separately by logistic regression.

RESULTS

162 male farmers were surveyed (median age 50, 74% with high school education), including 99 grower-breeders and 63 winegrowers, with differences in farm size, labour structure and employment status. Preventive measures were not implemented systematically: 59% wore gloves, 65% washed their hands and 45% read hazard information on labels. Agricultural specialisation was a major factor influencing behaviour as well as psychosocial determinants (self-efficacy, perceived barriers and social norms). In contrast, sociodemographic factors and knowledge levels had little effect.

CONCLUSION

The adoption of pesticide risk prevention behaviours remains limited over time, even in high-income countries. Our study demonstrates that (1) behaviours relying on distinct determinants should be analysed separately, (2) agricultural specialisation is a major factor influencing behaviours and (3) psychosocial variables play a predominant role in behaviour adoption. This appraisal is crucial for designing an appropriate intervention targeting French farmers.
