The aims of this study are (1) to assess changes in infant WHO growth indicators (weight-for-age, weight-for-length, and head circumference z-scores) from birth to 12 months of age as a function of feeding practices (FP) and (2) to describe the proportion of infants experiencing rapid weight gain (RWG; defined as change in weight-for-age z-score of ≥0.67 between birth and six months) among different FP. The modified Infant Feeding Practices Study II questionnaire was administered to 149 diverse caretakers/mothers of infants who were less than six months of age in a pediatric outpatient clinic. Growth as a function of FP was assessed using repeated measures ANOVA, while logistic regression was used to describe the correlates of RWG. The largest proportion of caretakers was African American (37%), 46% completed college, and 48% were enrolled in the Women, Infants, and Children (WIC) program. Regarding FP, 32% of infants were formula fed, and 18% were breastfed, with the remaining being either mixed fed or complementary fed, with nearly 40% of infants demonstrating RWG. While changes in weight-for-age z-scores differed among FP across time (p<0.05), observed patterns for head-circumference-for-age and weight-for-length z-scores did not. Various demographic correlates (caretaker race-ethnicity, education, and WIC enrollment) were associated with FP. Only the patterns of change in weight-for-age z-scores at 9 and 12 months differed among FP (with breastfeeding being the lowest at both time points). Further study is needed to adequately characterize the correlates of infant growth performance and growth patterns among different FP in such diverse samples. Continued research will allow for the development of an easy-to-use, succinct questionnaire that will allow healthcare providers to individualize feeding recommendations for caretakers of infants.
（1）评估婴儿从出生到12个月大时，世界卫生组织生长指标（年龄别体重、身长别体重和头围z评分）随喂养方式（FP）的变化情况；（2）描述不同喂养方式下体重快速增加（RWG；定义为出生至6个月期间年龄别体重z评分变化≥0.67）的婴儿比例。对一家儿科门诊中149名年龄小于6个月婴儿的不同看护人/母亲进行了改良版的《婴儿喂养方式研究II》问卷调查。使用重复测量方差分析评估生长情况与喂养方式的关系，同时使用逻辑回归来描述体重快速增加的相关因素。最大比例的看护人为非裔美国人（37%），46%完成了大学学业，48%参加了妇女、婴儿和儿童（WIC）项目。关于喂养方式，32%的婴儿采用配方奶喂养，18%采用母乳喂养，其余为混合喂养或辅食喂养，近40%的婴儿出现体重快速增加。虽然年龄别体重z评分的变化在不同喂养方式随时间存在差异（p<0.05），但年龄别头围和身长别体重z评分的观察模式并无差异。各种人口统计学相关因素（看护人的种族/民族、教育程度和WIC登记情况）与喂养方式有关。仅9个月和12个月时年龄别体重z评分的变化模式在不同喂养方式之间存在差异（两个时间点母乳喂养的情况都是最低的）。需要进一步研究，以充分描述如此多样化样本中不同喂养方式下婴儿生长表现和生长模式的相关因素。持续的研究将有助于开发一种易于使用、简洁的问卷，使医疗保健提供者能够为婴儿看护人提供个性化的喂养建议。
