摘要
采用呼气氢试验(HBT)对来自拉萨地区30名藏族中学生和重庆地区30名汉族中学生的乳糖吸收不良和乳糖不耐受进行了检测,测定结果显示:藏族学生组乳糖吸收不良者21例(70%),乳糖不耐受2例(9.57%);与汉族学生组乳糖吸收不良29例(96.67%),乳糖不耐受16例(55.17%)相比,藏族学生乳糖吸收不良和乳糖不耐受的发生率分别均明显低于汉族学生(P<0.01和P<O05)。本文说明乳糖吸收不良的显著种族差异可能与两民族长期生活环境与饮食习惯的不同有关。
actose malabsorption and lactose intolerance were determined in 30 Tibetan teen-agers and 30 Han teen-agers byhybrogen breath test(HBT),There were 21 cases of lactose malabsorption in 30 Tibetan tenn- agers(70%)and 2 cases oflactose intolerance in those 21 lactose malabsorbers(9.57%)However,lactose malabsorption was found in 29 out of 30cases(96.67%)and lactose intolerance 16 out of 29 cases(55 17%)of lactose malabsorption in Han teen-agers. The fre-quencies of lactose malabstorption and lactose intolerance in Tibetan teen-agers were obviously lower than those ofHan'sre-spoctively(P<0.01 & P < 0. 05) It is proposed that the difference of frequencies in lactose malabsorption and lactose in-tolerance betWeen Tibetan and Han may be due to their distinctive enviromental factors and dietarv habits.
