The utility of health education among lead workers: the experience of one program.
Health education represents a fundamental tool in the prevention of occupational diseases. For lead-exposed workers, work practices, personal hygiene, and life habits are certainly influences in the amount of the metal absorbed in the body. This study evaluated the effectiveness of a health education program in 50 workers exposed to inorganic lead employed in seven small factories. The study was performed in 3 phases over one year. Before the program, blood lead levels were measured, and a questionnaire was administered in order to evaluate the baseline knowledge of the workers about lead poisoning and its prevention. After the health education program, the blood lead levels decreased (from 38.2 to 32.3 micrograms/dl) and the questionnaire scores improved in a highly significant manner (p < 0.001). These results were obtained both in the short (4 months) and in the medium term (1 year). The reduction of blood lead concentrations seemed to be due to changes in hygienic behaviors and life habits, such as alcohol consumption or cigarette smoking, probably induced by an increase in specific knowledge about the prevention of lead damages.
