The incidence and length of breast feeding of LBW (less than or equal to 2500 grams) infants were investigated. A marked increase from 1979 to 1982 was noted: the incidence rose from 78% to 91% and the proportion of infants breast fed for 3 months rose from 54% to 67%. A breast feeding promotion programme did not influence the length of breast feeding of LBW infants within one year of the intervention. Smaller infants, those with RDS and those from lower social classes were breast fed less than others.
对低体重（小于或等于2500克）婴儿的母乳喂养发生率及持续时间进行了调查。结果发现，1979年至1982年期间有显著增长：发生率从78%升至91%，母乳喂养3个月的婴儿比例从54%升至67%。在干预的一年内，一项母乳喂养促进计划并未影响低体重婴儿的母乳喂养持续时间。较小的婴儿、患有呼吸窘迫综合征的婴儿以及社会阶层较低的婴儿母乳喂养次数少于其他婴儿。
