Objective: Evaluating the impact of educational intervention concerning knowledge, attitudes and practices (KAP) aimed at changing behaviour in how pesticides and organophosphates are applied in a sample of potato farmers from seven municipalities in the Boyacá department of Colombia in connection with occupational health and labour risks.
Materials and methods: This was a nested, before-after, intervention study. A participative strategy-based occupational health and labour risk educational intervention was used with 659 potato farmers. Knowledge, attitudes and practice concerning these matters were evaluated prior to and following the intervention.
Results: Statistically significant changes in knowledge were recorded; lesser significance was recorded regarding attitudes and practices.
Discussion: Educational interventions in vulnerable, low scholastic level populations require ongoing accompaniment and support for achieving significant changes in health practice.
