Lactobezoars have been reported with increasing frequency in low-birth-weight infants. The etiology of a lactobezoar is not well understood and is probably multifactorial. During a 2 1/2-year period, 29 of 442 infants weighing less than 2,000 g who were fed casein-predominant formulas had lactobezoars. During the subsequent 14-month period, 223 infants weighing less than 2,000 g were fed a whey-predominant formula, and none had lactobazoars. There have been no reports of lactobezoars in infants fed human milk or whey-predominant formulas. It would appear that the presence of casein as the predominant protein is necessary for the development of a lactobezoar.
在低体重婴儿中，乳酸乳石的报告频率越来越高。乳酸乳石的病因尚不完全清楚，可能是多因素的。在2年半的时间里，442名体重不足2000克且喂食以酪蛋白为主的配方奶粉的婴儿中有29名出现了乳酸乳石。在随后的14个月里，223名体重不足2000克的婴儿喂食了以乳清为主的配方奶粉，没有一例出现乳酸乳石。没有关于喂食母乳或以乳清为主的配方奶粉的婴儿出现乳酸乳石的报告。看来，以酪蛋白作为主要蛋白质的存在是乳酸乳石形成的必要条件。
