ABSTRACT

Objective To master the results of examination and evaluation of coal-burning-borne endemic fluorosis in Shanxi Province,and to provide a scientific basis for further prevention and treatment of the disease.Methods In 2012-2015,the prevention and control situation and condition survey were carried out in all coalburning-borne endemic fluorosis villages of 20 counties in Shanxi Province.A county-level self-inspection and a provincial-level spot-check were conducted to investigate the changes of improved stove and correct usage of the improved stove,and the correct drying of corn and pepper for human consumption.Children aged 8 to 12 were examined for dental fluorosis.The endemic areas were selected according to the Control Standards of Endemic Fluorosis in Endemic Areas (GB 17017-2010) and Eliminating Standards of Coal-burning Type Endemic Fluorosis,and dental fluorosis children was diagnosed based on the Diagnosis of Dental Fluorosis method (WS/T 208-2011).Results Totally 3 371 villages and 716 683 households were investigated,the rates of the improved stove and the correct usage of the improved stove were 98.72％ (707 502/716 683) and 98.74％ (698 608/707 502);the correct drying rate of corn and pepper for human consumption was 99.85％ (715 605/716 683);the dental fluorosis rate of 8 to 12 years old children and the dental fluorosis index were 6.41％ (6 762/105 453) and 0.14.A total of 20 counties in the province,9 counties had reached the control standards,11 counties had reached the elimination standards.Provincial and municipal level checked a total of 57 towns,157 villages,and the results of the overall compliance rate was 87.26％ (137/157).Conclusions The prevention and control effect is obvious on coalburning-borne endemic fluorosis in Shanxi Province.Disease surveillance,health education,the management and maintenance work on defluoridation stoves are keys in control of coal-burning-borne endemic fluorosis.
