Objective:To observe and evaluate the effect of health education on drinking brick-tea type fluorosis in Zhiduo County, Qinghai Province, so as to provide basis for further formulating health education strategies.Methods:From April 2019 to April 2020, according to the historical prevalence of drinking brick-tea type fluorosis in Zhiduo County, Qinghai Province, 3 townships (towns) were selected to carry out the health education activities on drinking brick-tea type fluorosis for students of grade 4 - 6, village doctors, adults and monks in each township (town). We carried out a one-year publicity on the prevention and treatment of drinking brick-tea type fluorosis, distributed health education materials and organized health education activities. Before and after the intervention, we conducted a questionnaire survey on health education among the target population (grade 4 - 6 students, village doctors, adults and monks), to evaluate the awareness rate and behavior formation rate of fluorosis prevention and control, and to evaluate the intervention effect.Results:A total of 86 students of grade 4 - 6, 40 village doctors, 42 adults and 20 monks were investigated, after the intervention, the awareness rates of prevention and treatment of drinking brick-tea type fluorosis in grade 4 - 6 students, village doctors, adults and monks were 87.98% (227/258), 96.67% (116/120), 81.75% (103/126), 83.33% (50/60), respectively, which were significantly higher than those before the intervention [38.38% (76/198), 83.33% (100/120), 15.45% (19/123), 28.89% (13/45), P < 0.05].
