摘要
目的应用聚类分析方法对全国饮茶型氟中毒流行现况调查数据进行分析,明确全国各病区省级或市级病情的分类层次,以指导饮茶型氟中毒的防治。方法利用2007年全国饮茶型氟中毒流行现况调查数据库,以Ⅱ度及以上临床氟骨症检出率为聚类指标,对全部调查资料进行聚类分析,绘制聚类图,根据聚类结果进行方差分析以及两两比较。结果全国饮茶型氟中毒病区从省级层面可分为三类:一类地区包括西藏和四川,二类地区为青海,三类地区包括内蒙古、甘肃、新疆和宁夏。从地市级层面也可分为三类:一类地区包括四川阿坝州、西藏日喀则地区及拉萨市;二类地区包括内蒙古乌兰察布市、呼伦贝尔市、包头市,青海海北州、果洛州、海西州、西宁市、海东地区,四川甘孜州,甘肃陇南市、酒泉市,新疆乌鲁木齐市和博尔塔拉州;其他地市(州、盟)为三类地区。省级及地市级一、二、三类地区Ⅱ度及以上临床氟骨症检出率(35.18%、16.21%、5.22%,41.16%、19.64%、4.19%)任意两类间比较差异均有统计学意义(P均〈0.05)。结论全国省级层面与地市级层面饮茶型氟中毒流行程度可以应用聚类分析法进行分类,聚类分析结果可以为国家有效落实饮茶型氟中毒防治措施提供科学依据。
Objective Cluster analysis method was applied to analyze the data of brick-tea-born fluorosis, to clarify the provincial and .municipal classification hierarchy in nation-wide epidemic areas and to guide the prophylaxis and treatment of the disease. Methods Prevalence survey database of the 2007 national brick-tea-born fluorosis was analyzed. Detection rate of second degree and above clinical skeletal fluorosis as clustered index, clustering analysis of all survey data was carried out, clustering figure was drawn, and analysis of variance and multiple comparison was done. Results The provincial level of the nation-wide epidemic areas of the brick-tea- born fluorosis could be classified into three categories: the first category including Tibet and Sichuan province, the second category including Qinghai province, and the third including Inner Mongolia, Gansn, Xinjiang and Ningxia provinces; The city-level they were also could be classified into three categories: the first category including Aba, Shigatse region and Lhasa, the second including Wulanchabu, Hulun Buir, Baotou, Qinghai state, Guoluo state, Haixi state, Xining city, Haidong state, Ganzi state, Longnan city, Jiuquan city, Urumqi city and the state of Bortala, and the other cities were the third category cities. The differences of clinical skeletal fluorosis detection rate between the first, second, and third provincial and municipal categories(35.18%, 16.21%, 5.22%, 41.16%, 19.64%, 4.19%) were statistically significant(all P 〈 0.05). Conclusions Brick-tea-born fluorosis can be classifiedby using cluster analysis at the provincial and municipal levels. Cluster analysis results can provide a scientific basis for effective implementation of the prophylaxis and treatment of brick-tea-born fluorosis.
