2022年新疆生产建设兵团饮水型地方性氟中毒监测结果分析

Monitoring results of drinking water-type endemic fluorosis in Xinjiang Production and Construction Corps in 2022

目的了解新疆生产建设兵团(以下简称兵团)饮水型地方性氟中毒(以下简称饮水型氟中毒)控制情况,找出防治薄弱环节,为兵团饮水型氟中毒精准防控工作提供参考。方法自兵团疾病预防控制中心收集2022年1-12月兵团饮水型氟中毒病区监测数据,回顾性分析饮用水氟含量超标情况及8~12岁儿童氟斑牙患病情况。结果2022年兵团病区团场的水氟合格率为100.00%(62/62),病区连队的水氟合格率为99.44%(705/709)。病区团场8~12岁儿童氟斑牙患病率为3.38%(1412/41714),各年龄组间氟斑牙患病率比较,差异无统计学意义(χ^(2)=6.07,P=0.194)。水氟超标连队所在团场8~12岁儿童氟斑牙患病率(6.00%,106/1768)高于水氟合格连队所在团场氟斑牙患病率(3.27%,1306/39946),差异有统计学意义(χ^(2)=38.47,P<0.001)。结论2022年兵团饮水型氟中毒达到控制标准,但仍然要重视个别水氟超标连队的改水情况及对改水工程的维护,防止对病区儿童造成持续性氟斑牙损害,巩固防控成果。

Objective To investigate the control situation of drinking water-type endemic fluorosis(hereinafter referred to as drinking water fluorosis)in Xinjiang Production and Construction Corps(hereinafter referred to as the Corps),identify weak links in prevention and control,and provide reference for precise prevention and control of drinking water fluorosis in the Corps.Methods Monitoring data of drinking water fluorosis areas in the Corps from January to December 2022 were collected from the Corps Center for Disease Control and Prevention,the level of fluoride in drinking water and the prevalence of dental fluorosis in children aged 8-12 were analyzed retrospectively.Results In 2022,the qualified rate of water fluoride in the disease affected TuanChang of the Corps was 100.00%(62/62),and the qualified rate of water fluoride in the disease affected company was 99.44%(705/709).The prevalence of dental fluorosis in children aged 8-12 in the disease affected TuanChang was 3.38%(1412/41714),and there was no statistically significant difference in the prevalence of dental fluorosis among different age groups(χ^(2)=6.07,P=0.194).The prevalence of dental fluorosis in children aged 8-12 in the TuanChang where the company with water fluoride exceeding standard was located(6.00%,106/1768)was higher than that in the TuanChang where the company with qualified water fluoride was located(3.27%,1306/39946,χ^(2)=38.47,P<0.001).Conclusion In 2022,the drinking water fluorosis in the Corps has reached the control standard,but attention still should be paid to the water improvement situation and maintenance of water improvement projects in some water fluoride exceeding standard companies,in order to prevent sustained dental fluorosis damage to children in the affected areas,and consolidate the achievements of prevention and control.
