我们于1981年4～6月结合膳食营养调查在吐鲁番、哈密、阿勒泰地区,对维、汉,哈族农牧民共8,234人进行了口腔粘膜白斑罹患情况的调查。调查结果显示三民族白斑检出率有明显差別,标化检出率顺序为哈族>汉族>维族。哈族发病年龄最早;发病高峰期哈,维族明显早于汉族。三民族白斑检出率随年龄升高而升高,男性明显高于女性,与地区海拨气象条件无关。造成三民族白斑检出率差异的原因可能为:(1)风俗生活习惯的不同,(2)牙(牙合)发育的遗传因素。调查结果肯定了在影响白斑发病的诸因素中吸烟与白斑的关系;揭示了
We investigated the prevalence of oral leukoplakia in 8,234 people of Victoria, Han and Kazakh farmers and herdsmen in Turpan, Hami and Altay from April to June 1981 in combination with the dietary survey. The survey results showed that there was a significant difference in the detection rates of white national spot among the three ethnic groups. The order of the detection rate of standardization was Ha ethnic group> Han nationality> Uygur ethnic group. Kazak the earliest age of onset; the peak incidence Kazakhstan, Uygur significantly earlier than Han. The prevalence of leukoplakia in three ethnic groups increased with increasing age, significantly higher in males than in females, irrespective of regional weather conditions. The causes of the differences in the detection rates of the three national whitewings may be: (1) different customs and habits, and (2) genetic factors in the development of the occlusion. The findings confirm the relationship between smoking and leukoplakia among the factors affecting leukoplakia; revealed
