In a population study on the western coast of Greenland the incidence of sucrose malabsorption was estimated by means of sucrose tolerance tests in 190 persons. Small-intestinal disaccharidase activity was estimated in 19 patients. Sucrose malabsorption was present in 10.5% of the cases studied-a surprisingly high figure and much higher than the incidence reported elsewhere in the world. This incidence is, however, lower than that of lactose malabsorption in Greenland Eskimos (54%). In contrast to lactose malabsorption, sucrose malabsorption is present from birth; this may have important clinical implications since chronic diarrhoea and malnutrition are fairly common during infancy in Greenland.
在格陵兰岛西海岸的一项人群研究中，通过对190人进行蔗糖耐量试验来估计蔗糖吸收不良的发生率。对19名患者的小肠双糖酶活性进行了评估。在所研究的病例中，蔗糖吸收不良的发生率为10.5%——这一数字高得出奇，远高于世界其他地方报道的发生率。然而，这一发生率低于格陵兰爱斯基摩人乳糖吸收不良的发生率（54%）。与乳糖吸收不良不同，蔗糖吸收不良从出生时就存在；这可能具有重要的临床意义，因为在格陵兰岛，婴儿期慢性腹泻和营养不良相当常见。
