【摘要】 我们于1986～1987年在位于新疆南、北部、气候条件差别较大,但居民饮水氟含量相似的阿勒泰和莎车进行了气候与饮食习惯对氟斑牙影响的对照调查。结果表明,气候相对凉爽湿润的阿勒泰地区儿童恒牙氟斑牙率明显地低于干旱炎热的莎车绿洲;在阿勒泰地区,水氟条件相似的牧区汉族儿童氟斑牙率明显低于农区儿童,牧区哈萨克族儿童氟斑牙率略低于汉族儿童,但在水氟更低的城镇,哈萨克儿童氟斑牙率却反比牧区高,且明显高于当地汉族儿童,哈萨克族儿童尿氟高于当地汉族儿童。牧区居民吃肉和奶制品多于农区与城镇所致动物蛋白摄人量差异是引起相同水氟条件下氟斑牙率不同的主要原因,这在哈萨克族中最明显。哈萨克族习惯饮茶是引起尿氟较高的主要原因,饮食结构变化饮茶习惯不变,使居于水氟更低城镇哈萨克族儿童氟斑牙率反高于水氟较高的牧区,表明饮食习惯对氟斑牙流行有影响。更多还原

【Abstract】 An epidemiological investigation was conducted to estimate the influences of climate and people’s dietary habits on the prevalence of endemic fluorosis during 1986-1987. The investigated areas, Altai and Shache, are situated at the northern and southern extremities of Xinjiang respectively. Incidence of dental fluorosis in children 8-15 years old was less than 30% in Altai (water F-:0.73±0.48ppm, n = 28) but it was over 30% in Shache with a water fluoride of 0.75±0.36ppm (n = 24). The rate of dental fluorosis in Han children was 10.8% in Qinghe (Altai) and 60.8% in Zepu (Shache), while water fluoride contents were almost the same in both towns. The reason for the above result was that meteorological conditions were significantly different between the two areas. In Altai, dental fluorosis rate of Kazak residing in urban was the highest, which was higher than that of Han and still higher than that of Kazak in pastoral areas. The food for Kazak in pastoral areas are meat, milk and cheese with large quantities of milk-tea, but they usually change their foods into cereal with brick-tea when move into urban areas. The staple foods for the Han people are always cereal with small amounts of meat and milk.更多还原
