目的：配方奶喂养的婴儿体重增长快于母乳喂养的婴儿。这项研究评估了鼓励配方奶喂养者对婴儿饱腹感敏感是否会改变喂养方式，减少婴儿配方奶的摄入量和体重增加。设计：双盲，随机教育干预，有摄入和成长。在干预前（1至2个月）和干预后（4至5个月）测量。地点：加州萨克拉门托的妇女、婴儿和儿童诊所。参与者：筛选836名幼儿看护人；214人符合条件，104人同意参加。干预：对干预对象进行教育，提高他们对饱腹感的认识，并在4个月前不鼓励超过6盎司的奶瓶；干预组和对照组在4月龄后接受有关引入和喂养固体食物的教育。主要观察指标：配方奶粉摄入量（mL/24小时）和体重增加（g/周）。分析：采用双向协方差分析（ANCOVA）评价组间差异。结果：61名受试者完成了基线记录，44名受试者参加了课程，38名受试者完成了研究。尽管对教育干预有积极的反应，但奶瓶喂养行为没有变化（4至5个月时，两组婴儿的配方奶摄入量均超过1100毫升/天）。干预组婴儿生长发育明显高于对照组(P
Objective: Formula-fed infants gain weight faster than breastfed infants. This study evaluated whether encouraging formula-feeding caregivers to be sensitive to infant satiety cues would alter feeding practices and reduce infant formula intake and weight gain. Design: Double-blind, randomized educational intervention, with intake and growth. measured before (at I to 2 months) and after (4 to 5 months) the intervention. Setting: Women, Infants, and Children (WIC) clinics in Sacramento, California. Participants: 836 caregivers of young infants were screened; 214 were eligible, and 104 agreed to participate. Intervention: Intervention subjects received education promoting awareness of satiety cues and discouraging bottles containing more than 6 ounces before 4 months of age; intervention and control groups received education regarding introduction and feeding of solid food after 4 months of age. Main Outcome Measures: Formula intake (mL/24 hours) and weight gain (g/week). Analysis: Differences between groups evaluated using 2-way analysis of covariance (ANCOVA). Results: Sixty-one subjects completed baseline records, 44 attended class, and 38 completed the study. Despite a positive response to the educational intervention, there was no change in bottle-feeding behaviors (formula intake at 4 to 5 months was more than 1100 mL/day in both groups). Infant growth in the intervention group was greater than in the control group (P
