Lactose malabsorption was studied by a breath hydrogen technique in 139 Samoan and 68 white schoolchildren. The Samoans were studied in four locations, two in Western Samoa and two in New Zealand, and the white children in both the Cook Islands and New Zealand. The prevalence of malabsorption varied with location: for Samoans it ranged from 41% to 60% in Western Samoa and 0% to 35% in New Zealand; white children had rates of 27% in the Cook Islands and 5% in New Zealand. Environmental factors rather than genetic factors are likely to play the main part in initiating if not perpetuating lactose malabsorption. In both races lactose malabsorption had no effect on the acceptance of, consumption of, and number of gastrointestinal symptoms caused by milk and milk biscuits. Children who had symptoms after consuming a particular dairy product were more likely to say they disliked it than those who reported no symptoms.
采用呼气氢技术对139名萨摩亚学童和68名白人学童进行乳糖吸收不良研究。对萨摩亚学童的研究在四个地点展开，其中两个在西萨摩亚，两个在新西兰；对白人学童的研究在库克群岛和新西兰两地进行。吸收不良的患病率因地点而异：萨摩亚学童在西萨摩亚的患病率为41%至60%，在新西兰为0%至35%；白人学童在库克群岛的患病率为27%，在新西兰为5%。环境因素而非遗传因素即便不是导致乳糖吸收不良持续存在的主要因素，也很可能在引发该问题中起主要作用。在两个种族中，乳糖吸收不良对牛奶和牛奶饼干的接受度、摄入量以及所引发的胃肠道症状数量均无影响。食用特定乳制品后出现症状的儿童比未出现症状的儿童更有可能表示不喜欢该乳制品。
