背景：需要信息来设计辅食喂养方案对儿童辅食（CF）和母乳摄入量影响的研究。目的：我们评估了不同能量密度的辅食对膳食摄入稳定时间以及每日总能量摄入量（EI）和母乳摄入量的影响。设计：低[0.4 kcal/g（LD）]和高[1.5 kcal/g（HD）]能量密度的CFs每天喂食3次， 10 名儿童（9-18 个月）在 2 个随机分配的三个 8 天饮食周期（HD-LD-HD 或 LD-HD-LD）序列中进行随意母乳喂养。测量 CF 和母乳摄入量。结果：HD 饮食和母乳的摄入量没有随经期的日期变化，但 LD 饮食的摄入量逐渐增加。在每个序列的最后 2 个饮食周期的第 5-7 天，消耗的 LD 多于 HD 饮食（分别为 752 +/- 252 和 439 +/- 111 g/d，P < 0.001），但 HD 饮食中 CF 的 EI 更大。与 LD 饮食期间相比，HD 期间的母乳消耗量略少（分别为 192 115 和 234 +/- 121 g/d；P = 0.03），但每日总 El 较高（分别为 774 +/- 175 和 441 +/- 85 kcal/d；P < 0.001）。 结论：关于新引入的饮食对这些饮食和每日摄入量的影响的新信息母乳可用于设计未来的研究。尽管 HD 饮食对母乳摄入量有负面影响，但每日总 EI 更高。
Background: Information is needed to design studies of the effects of complementary feeding regimens on children's intakes of complementary foods (CFs) and breast milk.Objective: We evaluated the effects of varied energy density of CFs on the time until stabilization of dietary intakes and on total daily energy intakes (EIs) and breast-milk intakes.Design: CFs with low [0.4 kcal/g (LD)] and high [1.5 kcal/g (HD)] energy density were fed 3 times/d to 10 children (aged 9-18 mo) during 2 randomly assigned sequences of three 8-d diet periods (HD-LD-HD or LD-HD-LD) along with ad libitum breastfeeding. CF and breast-milk intakes were measured.Results: Intakes of the HD diet and breast milk did not vary by day of period, but intake of the LD diet increased progressively. During days 5-7 of the last 2 diet periods in each sequence, more of the LD than of the HD diet was consumed (752 +/- 252 and 439 +/- 111 g/d, respectively, P < 0.001), but EIs from CFs were greater with the HD diet. Breast-milk consumption was slightly less (192 115 and 234 +/- 121 g/d, respectively; P = 0.03) but total daily El was greater (774 +/- 175 and 441 +/- 85 kcal/d, respectively; P < 0.001) during the HD than during the LD diet period.Conclusions: New information on the effects of newly introduced diets on daily intakes of these diets and of breast milk can be used to design future studies. Total daily EIs were greater with the HD diet despite its negative effects on breast-milk intakes.
