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)、18.61％(75/403)、20.72％(104/502),组间比较差异无统计学意义(x2=2.90,P＞0.05).3个县2010年氟斑牙检出率调查结果与2000年[34.20％(7 805/22 821)、39.77％(1 782/4 481)、60.88％(2 806/4 609)]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％(9 463/27 596)、36.30％(2 708/7460)、35.72％(1 896/5 308)]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 1986[34.29％ (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.
