摘要
目的了解河南省饮水型地方性氟中毒(简称地氟病)流行现状,评估防治效果,为制定进一步防治政策提供依据。方法2021年4-11月,在河南省17个省辖市和9个省直管县(市)的112个饮水型地氟病病区县(市、区,以下简称县)的所有病区村开展饮水型地氟病监测,收集病区县及病区村的基本情况,以村为单位测定病区居民户饮用水氟含量和调查8~12岁儿童氟斑牙患病情况。结果截至2021年底,河南省112个病区县均有饮水型地氟病流行,涉及17450个病区村,其中落实降氟改水措施的病区村有17433个,改水率为99.90%(17433/17450);水氟合格病区村有14920个,水氟合格率为85.50%(14920/17450)。全部病区村共有改水工程4232个,工程正常运转率为97.09%(4109/4232),工程水氟合格率为93.03%(3937/4232)。全省儿童氟斑牙总检出率为9.64%(39391/408584),中、重度氟斑牙共占8.08%(3182/39391),氟斑牙指数为0.18,氟中毒流行强度属于阴性。结论2021年河南省饮水型地氟病流行广泛,病区村降氟改水措施已经基本落实,但部分病区村水氟含量仍不达标,部分改水工程不能全年正常运转。今后需要针对上述问题逐一整改,巩固饮水型地氟病防治成果。
Objective To investigate the epidemic situation of drinking water-borne endemic fluorosis in Henan Province,evaluate the effectiveness of prevention and control measures,and provide a basis for formulating further prevention and control policies.Methods From April to November 2021,a census of all diseased villages registered in 112 drinking water-borne endemic fluorosis counties(cities,districts,hereinafter referred to as counties)of 17 provincial-level cities and 9 provincial-level counties(cities)in Henan Province was conducted to collect the basic information of diseased counties and villages.The content of fluoride in drinking water and the prevalence of dental fluorosis in children aged 8-12 years old were measured on a village by village basis.Results By the end of 2021,drinking water-borne endemic fluorosis was prevalent in 112 diseased counties in Henan Province,involving 17450 diseased villages.Among them,17433 villages had implemented measures to reduce fluoride and improve water quality,with a water improvement rate of 99.90%(17433/17450).There were 14920 villages with qualified water,and the qualified rate of water fluoride was 85.50%(14920/17450).There were a total of 4232 water improvement projects in all diseased villages,with a normal operation rate of 97.09%(4109/4232)and a qualified rate of 93.03%(3937/4232)for water fluoride in the projects.The total detection rate of dental fluorosis in children in the province was 9.64%(39391/408584),with moderate to severe dental fluorosis accounted for 8.08%(3182/39391),the dental fluorosis index was 0.18.The prevalence of fluorosis was negative.Conclusions In 2021,the prevalence of drinking water-borne endemic fluorosis is widespread in Henan Province,and measures to reduce fluoride and improve water quality in diseased villages have been basically implemented.However,the fluoride content of water in some villages still does not meet the standard,and some water improvement projects cannot operate normally throughout the year.In the future,it is necessary t
