目的:了解新昌县农村饮水型地方性氟中毒(地氟病)病区病情及降氟改水工程现状。方法:对新昌县农村6个改水后地氟病病区村进行饮水含氟量测定,并对8~12岁儿童、16岁以上成人分别进行氟斑牙、氟骨症临床检查。结果:2个病区村水氟均值超过控制标准;调查8~12岁儿童60名,氟斑牙患病率为31.67%,氟斑牙指数为0.67。检查16岁以上成人747例,氟骨症临床症状检出率为23.03%。女性(31.07%)高于男性(15.78%),两者经检验差异明显(χ2=24.59,P<0.05)。氟骨症患者主要集中在50岁以上人群,共151例,占87.79%。结论:新昌县氟病区村病情仍然比较严重,提示地氟病潜在的流行因素尚未有效控制。
Objective: To understand the status of endemic fluorosis (Fluorosis) in rural drinking water area in Xinchang County and the status quo of fluoride reduction and water diversion project. Methods: The fluorine content of drinking water was measured in six villages with changed water quality in Xinchang County, and clinical examination of dental fluorosis and skeletal fluorosis were carried out on children aged 8 ~ 12 years and adults over 16 years old respectively. Results: The fluoride content of water in the two wards exceeded the control standard. 60 children aged 8-12 years were investigated. The prevalence of dental fluorosis was 31.67% and the dental fluorosis index was 0.67. 747 adults over the age of 16 were examined. The detection rate of clinical symptoms of skeletal fluorosis was 23.03%. Women (31.07%) were higher than men (15.78%). The differences between the two groups were significant (χ2 = 24.59, P <0.05). Patients with skeletal fluorosis mainly concentrated in people over the age of 50, a total of 151 cases, accounting for 87.79%. Conclusion: The incidence of Fluorosis in Xinchang County is still relatively serious, suggesting that the potential epidemic factors of Fluorosis have not yet been effectively controlled.
