摘 要:目的探究并分析高氟高碘饮水对潍坊地区农村学龄儿童氟斑牙病的影响。方法按照潍坊地区水中氟碘含量,选取本地区abc三个村学龄儿童作为研究对象,每个村选取50例儿童,分别记为高氟高碘组、高氟适碘组、对照组(适氟适碘),测定并记录下三组儿童尿碘、氟含量以及氟斑牙发生情况,并对儿童氟斑牙的影响因素进行多因素逻辑回归分析,探究其与氟斑牙发生发展的关系。结果三组儿童尿氟、尿碘含量比较差异具有统计学意义(F=20.54,P=0.001;F=18.26,P=0.001)。其中高氟适碘组儿童尿氟和尿碘含量最高,其次是高氟高碘组,对照组儿童尿氟和尿碘含量最低。经秩和检验,三组儿童氟斑牙发生情况差异明显(u1-2=2.53;u1-3=2.62;u2-3=3.82,P<0.05),具有统计学意义。三组儿童氟斑牙率差异明显(F=11.01,P=0.003),具有统计学意义。其中高氟适碘组氟斑牙发生率最高,其次为高氟高碘组儿童,对照组氟斑牙发生率最低。三组儿童氟斑牙指数分别为1.52、1.60、0.75,差异具有统计学意义(F=12.41,P<0.05)。经多因素逻辑回归分析,水氟含量与儿童氟斑牙发生情况具有统计学意义(Waldχ2=7.769,P=0.012),随着水氟含量升高,儿童氟斑牙发生率明显升高。结论水氟含量与学龄儿童氟斑牙发生呈正相关,而在高氟情况下,适碘组的儿童氟斑牙发生率明显高于高碘组儿童,可能与碘离子氟离子交互作用有关,尚待进一步研究。
Objective To explore and analyze the effects of high-fluoride and high-iodine drinking water on dental fluorosis in rural school-age children in Weifang. Methods According to the fluoride and iodine content in water in Weifang, school-age children from three villages abc in the area were selected as the research subjects. Fifty children were selected from each village and recorded as the high-fluoride and high-iodine group, the high-fluoride and appropriate-iodine group, and the control group (appropriate-fluoride and appropriate-iodine). The urinary iodine and fluoride content of the three groups of children and the occurrence of dental fluorosis were measured and recorded. Multivariate logistic regression analysis was performed on the influencing factors of dental fluorosis in children to explore their relationship with the occurrence and development of dental fluorosis. Results The differences in urinary fluoride and iodine content among the three groups of children were statistically significant (F=20.54, P=0.001; F=18.26, P=0.001). The urinary fluoride and iodine content of the children in the high-fluoride and appropriate-iodine group was the highest, followed by the high-fluoride and high-iodine group, and the urinary fluoride and iodine content of the children in the control group was the lowest. The rank sum test showed that the incidence of dental fluorosis among the three groups of children was significantly different (u1-2=2.53;u1-3=2.62;u2-3=3.82,P<0.05), which was statistically significant. The dental fluorosis rate among the three groups of children was significantly different (F=11.01,P=0.003), which was statistically significant. The incidence of dental fluorosis was the highest in the high-fluorine and appropriate-iodine group, followed by the high-fluorine and high-iodine group, and the incidence of dental fluorosis in the control group was the lowest. The dental fluorosis indexes of the three groups of children were 1.52, 1.60, and 0.75, respectively, and the difference was statistically significant (F=12.41,P<0.05). The multivariate logistic regression analysis showed that the water fluoride content was statistically significant with the incidence of dental fluorosis among children (Waldχ2=7.769,P=0.012). With the increase of water fluoride content, the incidence of dental fluorosis among children increased significantly. Conclusion The fluoride content in water is positively correlated with the incidence of dental fluorosis in school-age children. Under high fluoride conditions, the incidence of dental fluorosis in the children in the appropriate iodine group was significantly higher than that in the high iodine group, which may be related to the interaction between iodine ions and fluoride ions, and further research is needed.
