摘要
目的探讨解决我国乳糖不耐受儿童的饮奶问题。方法在北京市郊募集10～11岁小学生106名,经筛查后选择乳糖不耐受小学生68例,采用交叉实验设计,应用呼气氢法研究了乳糖不耐受小学生饮用乳糖酶发酵型低乳糖牛奶、调配型低乳糖牛奶、酸牛奶后以及在随餐饮用普通牛奶时乳糖不耐受的发生情况。结果经症状调查和口服25 g 乳糖后3 h 呼气氢的检查结果,儿童中乳糖不耐受的发生率为80.2%;饮用250 ml 普通牛奶、经乳糖酶发酵型低乳糖牛奶、调配型低乳糖牛奶、酸牛奶及随餐饮奶250 ml 后,儿童的乳糖不耐受发生率分别为21.1%(12/57)、0.0%(0/25)、6.1%(2/33)、8.6%(3/35)和13.6%(3/22)。结论饮用低乳糖牛奶和酸牛奶可有效降低儿童乳糖不耐受的发生。
Objective To identify methods in reducing the prevalence of lactose intolerance in children. Methods A hydrogen respiration test （HRT） method was used in screening lactose intolerance （LI） subjects after taking 25 g of lactose among 106 children aged from 10 to 11 years old in a primary school located in the suburban area of Beijing. A cross-design was used to detect the effects of low lactose milk, yogurt and cereal-effect among 68 selected LI children. Results The incidence of LI was 80. 2% after the children took 25 g of lactose, and after taking a 250 ml of full milk, lactase-fermented milk, confected milk, yogurt, or milk with meal, the LI incidences were 21.1% （ 12/57）, 0% （0/25）, 6. 1% （2/33）, 8.6% （3/35） and 13. 6% （3/22） respectively. Condusion Low lactose milks and yogurt could reduce the LI incidence among LI children significantly.
