目的为了解潮阳市(现已划归为汕头市潮阳区和潮南区)饮水型高氟区10多年的改水工程及预防地氟病的效果,对潮阳市高氟区饮水型高氟区改水后儿童氟斑牙患病情况进行了流行病学调查分析。方法对高氟区各种饮水类型进行布点抽样,测定其水氟含量;对高氟区8～15岁儿童进行氟斑牙患病情况普查;以资料档案查询法、访谈法收集改水前的改水降氟基本情况及8～15岁儿童氟斑牙患病情况。结果潮阳市饮水型高氟区改水后,居民饮用水含量不超过1.0mg/L,且96.37%的病区人口都饮用上低氟含量的水。改水后,儿童氟斑牙患病率已由改水前的62.01%降至36.01%,有差异、有高度统计学意义(P<0.01)。儿童氟斑牙患病率与改水年限有关,改水超过8年以后,儿童氟斑牙患病率可降至非病区水平。结论该市高氟区改水成效显著,病情呈下降趋势,以改水降氟和健康教育为主的综合防治措施,是防治饮水型地氟病切实可行的措施。
Objective To understand the effect of water diversion project and prevention of dexamethasone in Chaoyang City (now classified as Chaoyang District and Chaonan District, Shantou City) drinking water high fluoride area for more than 10 years, Epidemiological investigation and analysis of the prevalence of dental fluorosis in children after water change. Methods Various types of drinking water in high fluoride area were spot-sampled to determine the content of fluoride in water. The prevalence of dental fluorosis in children aged 8-15 years in high-fluoride area was surveyed by questionnaire, interviews Change the basic situation of fluoride water and children aged 8 to 15 dental fluorosis prevalence. Results After the water-drinking high-fluoride area of Chaoyang changed water, the residents’ drinking water content did not exceed 1.0mg / L, and 96.37% of the ward population drank low-fluorine water. After water change, the prevalence of dental fluorosis in children dropped from 62.01% to 36.01% before water change, with a significant difference (P <0.01). The prevalence of dental fluorosis in children is related to the age of water diversion. After more than 8 years of water diversion, the prevalence of dental fluorosis in children can be reduced to the non-endemic level. Conclusion The effect of water diversion in high fluoride area of the city is remarkable, and the condition is in a downward trend. Comprehensive prevention and control measures based on water and fluoride reduction and health education are practical measures for preventing and treating fluorosis in drinking water.
