The effect of respiratory infections, diarrhea, illness-induced apathy, and of a summary variable of selected common symptoms on food intake was estimated from data collected on preschool children from rural Guatemala. The presence of selected common symptoms was associated with an average reduction in daily intake of nearly 20%, equivalent to 175 kcal and 4.8 g of protein. Effects were of similar magnitude for diarrhea and for apathy but lower for respiratory infections, namely 61 kcal and 1.0 g of protein. It is concluded that common illnesses are an important cause of low dietary intakes in children from Guatemama.
根据从危地马拉农村学龄前儿童收集的数据，估算了呼吸道感染、腹泻、疾病引起的冷漠情绪以及选定常见症状的综合变量对食物摄入量的影响。选定常见症状的出现与每日摄入量平均减少近20%有关，相当于175千卡热量和4.8克蛋白质。腹泻和冷漠情绪的影响幅度相似，但呼吸道感染的影响较小，即61千卡热量和1.0克蛋白质。得出的结论是，常见疾病是危地马拉儿童饮食摄入量低的一个重要原因。
