摘要
目的了解贵州省燃煤型地方性氟中毒（简称地氟病）病区实施综合防治措施前后儿童氟斑牙病情变化情况，为地方性氟中毒的可持续防治提供科学依据。方法2010年，按照整群单纯随机抽样方法，在贵州省遵义、开阳、龙里3个县各抽取1／5的乡镇，每个乡镇抽取1／5的村作为调查点，对调查点全体在校8～12岁儿童进行氟斑牙检查．并将调查结果与1986、2000年的历史病情进行纵向比较。氟斑牙诊断采用Dean法。结果遵义、开阳、龙里3个县8～12岁儿童氟斑牙检出率分别为23．76％（202／850）、15．77％（79／501）、11．17％（42／376）。3个县8、9、10、11、12岁年龄组儿童总的氟斑牙检出率分别为11．52％（19／165）、17．19％（44／256）、20．20％（81／401）、18．6l％（75／403）、20．72％（104／502），组间比较差异无统计学意义（x2=290，P〉0．05）。3个县2010年氟斑牙检出率调查结果与2000年[34．20％（7805／22821）、39．77％（1782／4481）、60．88％（2806／4609）]比较，差异均有统计学意义（x2值分别为37．81、110．91、350．76，P均〈0．01）；与1986年[34．29％（9463／27596）、36．30％（2708／7460）,35．72％（1896／5308）]比较，遵义县差异无统计学意义（x2=0．045，P〉0．05），开阳、龙里2个县差异均有统计学意义（x2值分别为14．35、626．39，P均〈0．01）。结论病区实施综合防治措施后干预效果明显，3个县8～12岁儿童氟斑牙检出率明显下降，已降至病区控制标准（30％）之下。今后应持续开展后期管理。并按照有关卫生标准有计划地组织达标考核验收。
Objective To explore the changes of children＇s dental fluorosis before and after implementation of comprehensive prevention and control intervention in coal-burning-borne endemic fluorosis areas of Guizhou Province, and to provide a scientific basis for making corresponding prevention and control measures. Methods In 2010, according to a simple-random cluster sampling method, 1/5 of the villages out of 1/5 of the towns of Zunyi, Kaiyang and Longli Counties, were selected as investigation sites for inspection of dental fluorosis in 8 - 12 years old children and a longitudinal comparison was done with historical related dental fluorosis （year 1986 and 2000）. Dental fluorosis of children was diagnosed by Dean method. Results In Zunyi, Kaiyang and Longli Counties,the detection rates of 8 - 12 years old children＇s dental fluorosis were 23.76%（202/850）, 15.77% （79/501） and 11.17%（42/376）, respectively. The detection rates of dental fluorosis in the 8, 9, 10, 11 and 12 years old age group of children were 11.52% （19/165）, 17.19% （44/256）, 20.20% （81/401）, 18.61% （75/403） and 20.72%（104/502）, respectively, and there was no significant difference between groups （X2= 2.90, P 〉 0.05）. The survey results of this investigation in the three counties in 2000 were 34.20%（7 805/22 821 ）, 39.77%（1 782/ 4 481）, 60.88%（2 806/4 609）, and the differences were statistically significant between the results of 2010 and 2000（X2 = 37.81, 110.91, 350.76, all P 〈 0.01）. And compared with the results of 1986134.29%（9 463/27 596）, 36.30% （2 708/7 460）, 35.72% （1 896/5 308）], the difference of Zunyi County was not statistically significant （X2 = 0.045, P 〉 0.05）, but for Kaiyang and Longli the differences were statistically significant（x2 = 14.35, 626.39, all P 〈 0.01 ）. Conclusions The effect of comprehensive prevention and control intervention is very obvious. In the 3 counties, the incidence rates of 8 - 12 years old children＇s dental fluorosis are already dropped to below 30% of the control standard. Subsequent management should be carried out and the state of disease should be evaluated for organization-assessment acceptance in accordance with relevant hygiene standards in a planned way.
