Lactose malabsorption was determined in 277 Mexican-American (MA) and 142 Anglo-American (AA) adults aged 18 to 94 years old, and correlated with nutrient intake assessed from 24-hr dietary recalls, as well as with milk and dairy product consumption. Lactose malabsorption occurred in 144 of 277 (53%) MA and 21 of 142 (15%) AA. Analysis of dietary questionnaires revealed no differences between lactose absorbers and malabsorbers within each ethnic group in their consumption of protein, calories, riboflavin, vitamin A, or calcium. Vitamin A, calcium, and riboflavin intake was greater in AA than in MA subjects. Milk and dairy product consumption was the same in lactose absorbers and malabsorbers in both ethnic groups. Nearly 60% of MA malabsorbers and 24% of AA malabsorbers recognized experiencing symptoms after milk ingestion. Although group differences in milk consumption on the basis of lactose absorption status are not apparent, individual lactose malabsorbers may alter milk ingestion in response to lactose-induced symptoms. Lactose malabsorption occurs in over half of MA adults and may in some individuals present a clinically relevant problem.
对277名年龄在18至94岁之间的墨西哥裔美国人（MA）和142名英裔美国人（AA）成年人进行了乳糖吸收不良测定，并将其与通过24小时饮食回顾评估的营养摄入量以及牛奶和乳制品消费量相关联。277名MA中有144名（53%）、142名AA中有21名（15%）发生乳糖吸收不良。对饮食问卷的分析显示，在每个种族群体中，乳糖吸收者和乳糖吸收不良者在蛋白质、卡路里、核黄素、维生素A或钙的摄入量方面没有差异。AA受试者的维生素A、钙和核黄素摄入量高于MA受试者。两个种族群体中乳糖吸收者和乳糖吸收不良者的牛奶和乳制品消费量相同。近60%的MA乳糖吸收不良者和24%的AA乳糖吸收不良者承认在摄入牛奶后出现症状。尽管基于乳糖吸收状态的牛奶消费量组间差异不明显，但个体乳糖吸收不良者可能会因乳糖引起的症状而改变牛奶摄入量。超过一半的MA成年人存在乳糖吸收不良，在某些个体中可能会出现临床相关问题。
