Evaluation of propagation effects of health education in the pilot a rea of endemic fluorosis of Guizhou province

Objective To assess the effects of health education.Methods The knowledge of endemic fluorosis and its control skills in the goal residents, changes in the related activities, fluoride contents in indoor air and main food, and fluoride level in urine of the children aged 8~12 were studied.Results More than 80% of the goal residents had the knowledge of endemic fluorosis and its control skills. 84% of families installed fluoride pollution-control stove. 97% of households stretched out the chimney to make the coal smoke outdoors. 96% of families did not bake the staple food with uncovered stoves. 70% of families sealed up and stored their staple food, and washed it before cooking. Fluoride level in indoor air decreased below the national standard for permitted concentration. The content of fluoride in the chili pepper significantly went down. Fluoride content in the corn reached the level of national health standard. Concentration of fluoride in urine of the children aged 8~12 was nearly normal.Conclusions Intervention of health education in fluorosis-prevalent areas that possess certain conditions of economy and education could open up the scope of prevention of endemic fluorosis, enhance the effects of control, and consequently reduce the investment of the Government.
