Previous studies of malnourished children in hospital have shown that their developmental quotients (DQS) improve as their nutritional status improves, but they have not taken into account the possible effects of being in hospital and of test practice. The present study assessed development of malnourished and adequately nourished children in hospital and found that mean DQS of each group rose to a similar extent during recovery from illness. It is concluded that DQS on admission to hospital were lowered by the children's discomfort and unhappiness at being in hospital, and/or by illness, and that rises in DQ shown by children recovering from malnutrition are not necessarily attributable to improving nutritional status.
以往针对住院营养不良儿童的研究表明，随着营养状况的改善，他们的发育商（DQ）会提高，但这些研究并未考虑住院因素及测试操作可能产生的影响。本研究评估了住院的营养不良儿童和营养充足儿童的发育情况，发现每组儿童在疾病康复过程中，平均发育商的提升幅度相近。由此得出结论，住院儿童入院时的发育商降低是由于住院带来的不适和不开心，和/或疾病所致，而从营养不良中康复的儿童发育商的上升并不一定归因于营养状况的改善。
