ABSTRACT

Objective To evaluate the control effects on coal-burning-borne endemic fluorosis in Shangli County and Yuanzhou District of Jiangxi Province in 2014.Methods Self-evaluation at the county level was carried out in all diseased villages in Shangli County and Yuanzhou District,including 145 villages of Shangli County and 32 villages of Yuanzhou District.Review at the provincial level was based on the results of selfevaluation of the county,3 towns were chosen in each county (district),3 villages were chosen in each town,a total of 18 villages were re-checked in Shangli County and Yuanzhou District,and 10 households were chosen to recheck in each village.According to the project requirements for endemic disease control,in all diseased villages of Shangli County and Yuanzhou District,self-evaluation results of the county was used to evaluate the status of the improved and the used stoves,and dental fluorosis of children aged 8-12.Review at the provincial level was carried,and the results were evaluated based on the Standards for Control Criteria for Endemic Fluorosis Areas (GB 17017-2010) and Elimination of Coal-burning-borne Endemic Fluorosis.Results Self-evaluation of the county110 443 households in Shangli County and 20 280 households in Yuanzhou District were investigated,the qualified rates of improved stoves were 92.45％ (102 109/110 443) and 98.28％ (19 932/20 280),respectively;the correct-usage rates of qualified stoves were 93.46％ (95 427/102 109) and 98.47％ (19 627/19 932),respectively.Dental fluorosis of 28 772 children were examined,the number of dental fluorosis was 5 730,the prevalence rate of dental fluorosis was 19.92％ (5 730/28 772);Shangli County and Yuanzhou District were up to the standard of fluorosis control,the rates of control were 95.17％ (138/145) and 100.00％ (32/32),respectively.Review at the provincial level180 households were selected,the qualified numbers of improved stoves and the correct-usage of qualified stoves were 179 and 177,respectively,the qualified rate of improved stoves was 99.44％ (179/180) and the correct-usage rates of qualified stoves was 98.88％ (177/179).Dental fluorosis of 805 children were examined,the number of dental fluorosis was 139,the prevalence rate of dental fluorosis was 17.27％ (139/805).The consistency rate of county-level and provincial-level was 88.89％ (16/18).Conclusion The control efficiency for coal-burningborne fluorides in Shangli County and Yuanzhou District of Jiangxi Province is obvious,the prevalence is under control.
