To assess the effects of common infections on dietary intake, 131 Peruvian infants were observed longitudinally. Home surveillance for illness symptoms was completed thrice weekly, and food and breast-milk consumption was measured during 1615 full-day observations. Mean (+/- SD) energy intakes on symptom-free days were 557 +/- 128 kcal/d (92.4 +/- 26.5 kcal.kg-1.d-1) for infants aged less than 181 d and 638 +/- 193 kcal/d (77.7 +/- 25.7 kcal.kg-1.d-1) for infants aged greater than 180 d. Statistical models controlling for infant age, season of the year, and individual showed significant 5-6% decreases in total energy intake during diarrhea or fever. There were no changes with illness in the frequency of breast-feeding, total suckling time, or amount of breast-milk energy consumed. By contrast, energy intake from non-breast-milk sources decreased by 20-30% during diarrhea and fever, and the small decrements in total energy consumption during illness were explained entirely by reduced consumption of non-breast-milk foods.
为评估常见感染对饮食摄入的影响，对131名秘鲁婴儿进行了纵向观察。每周三次对疾病症状进行家庭监测，并在1615次全天观察期间测量食物和母乳摄入量。181日龄以下婴儿在无症状日的平均（±标准差）能量摄入量为557±128千卡/天（92.4±26.5千卡·千克⁻¹·天⁻¹），180日龄以上婴儿为638±193千卡/天（77.7±25.7千卡·千克⁻¹·天⁻¹）。控制婴儿年龄、年份季节和个体因素的统计模型显示，腹泻或发烧期间总能量摄入量显著下降5 - 6%。母乳喂养频率、总吸吮时间或母乳能量摄入量在患病期间没有变化。相比之下，腹泻和发烧期间非母乳来源的能量摄入量下降了20 - 30%，患病期间总能量消耗的小幅下降完全是由于非母乳食品摄入量减少所致。
