我们评估了孟加拉国农村135名6-12月龄母乳喂养婴儿的营养摄入量，并检查了由于补充食物可能取代母乳而造成的营养权衡。观察员完成了12小时白天测量母乳和辅食的摄入量，前12小时的数据来自母亲回忆，估计总24小时的摄入量。平均而言，婴儿轻度消瘦（平均SD身高体重Z评分= -0.92 +/-0.88）和中度发育不良（身高年龄Z评分= -1.49 +/-0.96）。6-8个月和9-12个月的总能量摄入量分别为绝对能量需求（kJ/d）的88%和86%，每公斤体重需求的106%和105%，以及每公斤中位体重需求的97%和94%-长度。母乳在6-8个月和9-12个月分别贡献了78%和75%的能量摄入。平均用餐频率和能量密度的辅食一般与建议一致，但只有少量的食物提供。然而，只有72%的食物能量被消耗。总能量摄入量与进餐频率、每餐摄入量和母乳能量摄入量呈正相关，但与辅食能量密度无关。从辅食中摄取的能量与从母乳中摄取的能量呈负相关。这些饮食没有达到许多维生素和矿物质的推荐摄入量。我们的结论是，尽管补充食品的摄入量增加与总能量摄入量增加有关，但由于补充食品的微量营养素密度较低以及母乳的部分替代，微量营养素摄入量仍然较低。
We assessed the adequacy of nutrient intakes of 135 rural Bangladeshi breast-fed infants 6-12 mo of age and examined nutritional trade-offs due to possible displacement of breast milk by complementary foods. Observers completed 12-h daytime measurements of breast milk and complementary food intakes; data for the previous 12 h were obtained from maternal recall, yielding estimates of total 24-h intakes. On average, infants were mildly wasted (mean SD weight-for-length Z-score = -0.92 +/- 0.88) and moderately stunted (length-for-age Z-score = -1.49 +/- 0.96). Total energy intakes at 6-8 and 9-12 mo were 88 and 86% of absolute energy requirements (kJ/d), 106 and 105% of requirements per kg body weight, and 97 and 94% of requirements per kg median weight-for-length, respectively. Breast milk contributed 78% of energy intake at 6-8 mo and 75% at 9-12 mo. Mean meal frequency and energy density of complementary foods were generally consistent with recommendations, but only small amounts of food were offered. Nevertheless, only 72% of the food energy offered was consumed. Total energy intake was positively correlated with meal frequency, quantity consumed per meal, and energy intake from breast milk, but not with energy density of complementary foods. Energy intake from complementary foods was inversely related to energy intake from breast milk. The diets fell short of recommended intakes for numerous vitamins and minerals. We conclude that although greater intakes of complementary foods were associated with higher total energy intake, micronutrient intake remained low due to the low micronutrient density of the complementary foods consumed and the partial displacement of breast milk.
