摘要
目的了解江苏省饮水型氟中毒病区防治措施的实施进度,动态监测病情变化趋势,综合评价改水等其他因素对病情的影响。方法于2011-2015年,选择江苏省徐州沛县、连云港东海县、宿迁泗洪县3个氟中毒监测县,每个县抽取3个村共9个村做为监测村,采集水样并检测水氟值,按Dean法对全部8~12岁儿童的氟斑牙进行检查。结果 2011-2015年儿童氟斑牙检出率分别为33.68%(194/576),29.43%(176/598),27.26%(190/697),24.26%(163/672),26.84%(222/827),呈下降趋势(χ^2=88.821,P<0.05)。男童、女童的氟斑牙检出率分别为27.51%(631/2 294)和29.18%(314/1 076),差异无统计学意义(χ^2=6.785,P>0.05)。8~12岁儿童的氟斑牙检出率分别为28.57%(148/518),31.54%(211/669),27.91%(187/670),26.97%(192/712),25.84%(207/801),差异无统计学意义(χ^2=16.423,P>0.05)。未改水监测村、改水水氟超标监测村、改水水氟合格监测村氟斑牙检出率分别为36.58%(117/320),52.46%(192/366),23.70%(636/2 684),其中,改水水氟超标监测村儿童的氟斑牙检出率高于未改水监测村和改水水氟合格监测村,差异均有统计学意义(χ^2=26.694、31.469,均P<0.05);而改水水氟合格监测村与未改水监测村儿童的氟斑牙检出率间比较,差异无统计学意义(χ^2=2.131,P>0.05)。结论江苏省饮水型氟中毒总体病情逐步得到控制,改水后水氟超标对儿童氟斑牙影响较大。
Objective To understand the schedule implementation of drinking water fluorosis prevention and control in Jiangsu province and evaluate the influence of water supply improvement and other factors on endemic fluorosis. Methods Three endeminc fluorosis counties in Xuzhou, Lianyungang and Suqian were selected, three villages from each county were selected as the monitoring sites. The water fluoride was surveyed and the teeth examination was conducted in children aged 8 to 12 according to the method of Dean. Results The detection rates of dental fluorosis from 2011 to 2015 were 33.68%(194/576), 29.43%(176/598),27.26%(190/697),24.26%(163/672) and 26.84%(222/827) respectively (χ^2=88.821 ,P<0.05). The detectionrates of dental fluorosis among boys and girls were 27.51 %(631/2 294) and 29.18%(314/1 076) respectively (χ^2=6.785,P>0.05).The dental fluorosis detection rates of children aged 8 to 12 were 28.57% (148/518),31.54% (211/669),27.91 % (187/670), 26.97%(192/712) and 25.84%(207/801) respectively (χ^2=16.423,P>0.05). The detection rates of dental fluorosis in villages without water supply improvement and in water supply —improved villages with unqualified and qualified water fluoride concentration were 36.58%(117/320),52.46%(192/366) and 23.70%(636/2 684) respectively (χ^2=43.227,P<0.05). Conclusion Drinking water endemic fluorosis in Jiangsu province has been gradually controlled from 2011 to 2015, but the adverse effect of excessive fluoride exposure through drinking water on children still exists in the investigated areas.
