Abstract:
Objective To investigate and analyze the examination and acceptance results for coalburning-borne endemic fluorosis control and elimination in Hubei Province.Methods A county-level selfinspection and a provincial-level spot-check were conducted to investigate the status of improved-stove usage,the situation of correctly drying corn and chili,and the dental fluorosis prevalence among children aged 8 to 12 in 501 historic coal-burning-borne endemic fluorosis villages of 6 counties (cities) in Hubei Province from 2012 to 2014.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.Results The results of county-level inspection showed that the qualified rates of improved stoves,the correct-usage rates of qualified stoves,and the correctly drying rates of corn and chili were all higher than 98％ in targeted villages,and the prevalence rate of dental fluorosis of children was 7.73％ (2 319/30 003).The results of provincial-level recheck were more than 99％ and 8.25％ (353/4 277),respectively.The results of county-level inspection were of good consistency with those of provincial-level recheck (88.89％,48/54).Five counties (cities) but one had met the standard of fluorosis control or elimination.Conclusion Coal-burning-borne endemic fluorosis scope in Hubei Province is narrowed greatly and the prevalence rates are decreased significantly.
