Breastfeeding has been implicated in the establishment of infant appetite regulation, feeding patterns and body composition (BC). A holistic approach is required to elucidate relationships between infant and maternal BC and contributing factors, such as breastfeeding parameters. Associations between maternal and breastfed term infant BC ( = 20) and feeding parameters during first 12 months of lactation were investigated. BC was measured at 2, 5, 9 and/or 12 months postpartum with ultrasound skinfolds (US; infants only) and bioimpedance spectroscopy (infants and mothers). 24-h milk intake (MI) and feeding frequency (FFQ) were measured. Higher FFQ was associated with larger 24-h MI ( ≤ 0.003). Higher 24-h MI was associated with larger infant fat mass (FM) (US: ≤ 0.002), greater percentage FM (US: ≤ 0.008), greater FM index (FMI) (US: ≤ 0.001) and lower fat-free mass index (FFMI) (US: 0.015). Lower FFQ was associated with both larger FFM (US: ≤ 0.001) and FFMI (US: < 0.001). Greater maternal adiposity was associated with smaller infant FFM measured with US (BMI: < 0.010; %FM: = 0.004; FMI: < 0.011). Maternal BC was not associated with FFQ or 24-h MI. These results reinforce that early life is a critical window for infant programming and that breastfeeding may influence risk of later disease via modulation of BC.

母乳喂养与婴儿食欲调节、喂养模式和身体成分（BC）的建立有关。需要采用整体方法来阐明婴儿和产妇 BC 以及母乳喂养参数等因素之间的关系。研究了母乳喂养足月婴儿 BC（= 20）和哺乳期前 12 个月喂养参数之间的关系。产后 2、5、9 和/或 12 个月使用超声皮褶（仅婴儿）和生物阻抗光谱（婴儿和母亲）测量 BC。测量 24 小时牛奶摄入量（MI）和喂养频率（FFQ）。较高的 FFQ 与较大的 24 小时 MI 相关（≤0.003）。较高的 24 小时 MI 与婴儿脂肪量（FM）更大相关（US：≤0.002）、更大的百分比 FM（US：≤0.008）、更大的 FM 指数（FMI）（US：≤0.001）和更低的无脂肪质量指数（FFMI）（US：0.015）。较低的 FFQ 与更大的 FFM（US：≤0.001）和 FFMI（US：<0.001）相关。母体肥胖程度与 US 测量的婴儿 FFM 更大相关（BMI：<0.010；%FM：=0.004；FMI：<0.011）。母体 BC 与 FFQ 或 24 小时 MI 无关。这些结果表明，生命早期是婴儿编程的关键窗口，母乳喂养可能通过调节 BC 影响日后疾病的风险。
