摘要
目的研究经济状况对儿童饮水型氟中毒的流行病学特征及多种膳食营养素摄取水平的影响。方法选择总摄氟量和饮水氟含量相同、经济状况较富裕的天津市郊区某村和经济状况较贫困的内蒙古某旗某村共计194名8～12岁儿童为研究对象,采用3日膳食调查法分析人群膳食摄入情况,氟离子选择电极法测定尿氟含量、按Dean氏分类法检查受检者氟班牙病损程度,并利用SPSS统计软件进行数据分析。结果天津市郊区某村儿童摄入钾、钙、锌、磷、硒等8种矿物质营养素,蛋白质、脂肪能量营养素,维生素C等5种维生素的量高于内蒙古某旗某村,差异有统计学意义(P<0.05),天津市郊区某村儿童和内蒙古某旗某村晨尿尿氟浓度均值分别为5.20±2.75 mg/L和6.79±3.92 mg/L,差异有统计学意义(P<0.05),天津市郊区某村儿童氟中毒的患病主要以1～2度氟斑牙为主,内蒙古某旗某村氟中毒患病主要以3度氟斑牙为主,差异有统计学意义(P<0.05)。结论天津市郊区某村儿童膳食营养摄入状况好于内蒙古某旗某村儿童,天津市郊区某村儿童氟中毒的患病程度明显轻于内蒙古某旗某村儿童,增加多种膳食营养素的摄入量有利于提高儿童对氟的耐受。
To study the impact of economic status on epidemiological characteristics of children drink- ing - water type fluorosis and several dietary nutrients intake. Methods The two communities that patieipated in this study were a village of Inner Mongolia Autonomous Region and a village of Tianjin. Average water fluoride concentrations and total intake of fluoride in two sites were close to each other, but ecnomic status were not a- like. Participants were children aged 8 through 12 years. Food and nutrient intakes status were obtained from 3 -days diet records. Urinary fluoride excretion of morning urinary samples was measured by fluoride ion elec- trode. The Tooth Surface Index of Dean was applied to measure the prevalence and severity of dental fluorosis. All statistical analyses were carried out by means of SPSS software. Results The 8 mineral nutrients such as kalium, calcium, zinc, phosphorus and selenium; energy nutrients such as protein and fat; and 5 kind of vitamins such as vitamin C intakes of children in a vil- lage of Tianjin was higher than that in a village of Inner Mongolia Autonomous Region, and with the differences was statistically significant （P 〈 0. 05）. The average offasting urinary fluoride concentrations was 5.20 ± 2. 75 the village of Mongolia Autonomous Region, and with mg/L in the village of Tianjin and 6.79 ± 3.92 mg/L in the difference was statistically significant （P 〈 0. 05 ）. The prevalence of fluorosis in Inner Mongolia Autonomous Region was mainly in 3 degree of dental fluorosis; and in Tianjin was mainly in 1 - 2 degree of dental fluorosis, the difference was statistically significant （ P 〈 0. 05 ）. Conclusion The condition of dietary nutrients intake of the children in the village of Tianjin was better than the village of Mongolia Autonomous Region. The prevalence of fluorosis in Inner Mongolia Autonomous Region was obviously higher than that in Tianjin. The tolerable intake of fluoride in children increases with the increased intakes of dietary nutrients.
