Unhealthy behaviors are important problems in public health. Education is one of the best ways to change unhealthy behaviors. Interventions based on model and theories have many capacities for behavior change. Health Belief Model is one of the health education models that are useful for behavior change. This research has been performed in order to assess the effect of health education program based on health belief model (HBM) to prevent occupational respiratory diseases in workers.

  Methods

Data collecting tool were a self-administered questionnaire including 53 questions based on health belief model that was completed by the workers, in addition to the performance check list which was conducted by researcher via insensible controlling the workers' safety behaviour. Validity and reliability of the tools were examined prior to the study. Educational intervention was conducted in the first stage following by the second data collection one month later. The data of both experimental and control group were compared statistically before and after the intervention.

  Results
