Low income, primiparous mothers who had exclusively breast-fed for 4 mo were randomly assigned to one of three groups: 1) continued exclusive breast-feeding to 6 mo (EBF), 2) introduction of complementary foods at 4 mo, with ad libitum nursing 4-6 mo (SF), and 3) introduction of complementary foods at 4 mo, with maintenance of base-line nursing frequency 4-6 mo (SF-M). After the intervention phase (4-6 mo; n= 141), home visits were conducted for a subsample at 9 (n = 60) and 12 (n = 123) mo. At each visit, an observer recorded infant food intake at the midday meal and interviewed the mother regarding usual feeding patterns and the infant's acceptance of 20 common food items. All but two infants (1.5%) were breast-fed to 9 mo and all but eight (6%) to 12 mo. There were no significant differences among groups in breast-feeding frequency, amount or number of foods consumed at the midday meal, percentage of food offered that was consumed, usual daily number of meals and snacks, number of food groups consumed, or overall food acceptance score. Frequency of consumption of foods from eight different food groups (dairy, meats, eggs, grains, beans, fruits, vegetables, tubers) was not significantly different among groups except that, at 9 mo only, the SF group (but not the SF-M group) consumed more vegetables than did the EBF group. These results indicate that delaying the introduction of complementary foods until 6 mo does not adversely affect appetite or food acceptance among breast-fed infants.
低收入初产母亲中,那些纯母乳喂养4个月的母亲被随机分为三组:1)继续纯母乳喂养至6个月(纯母乳喂养组);2)4个月时引入辅食,4至6个月按需哺乳(辅食添加组);3)4个月时引入辅食,4至6个月维持基线哺乳频率(辅食添加-维持组)。在干预阶段(4至6个月;n = 141)结束后,对一个子样本在9个月(n = 60)和12个月(n = 123)时进行了家访。每次家访时,一名观察者记录婴儿午餐时的食物摄入量,并就通常的喂养模式以及婴儿对20种常见食物的接受情况与母亲进行访谈。除两名婴儿(1.5%)外,所有婴儿均母乳喂养至9个月,除八名婴儿(6%)外,所有婴儿均母乳喂养至12个月。三组在母乳喂养频率、午餐时摄入的食物量或种类、提供食物的摄入量百分比、通常每日的正餐和零食数量、摄入的食物种类数量或总体食物接受评分方面均无显著差异。除了在9个月时,辅食添加组(而非辅食添加-维持组)比纯母乳喂养组摄入更多蔬菜外,来自八个不同食物组(乳制品、肉类、蛋类、谷物、豆类、水果、蔬菜、块茎类)的食物消费频率在三组之间没有显著差异。这些结果表明,将辅食引入推迟至6个月不会对母乳喂养婴儿的食欲或食物接受度产生不利影响。
