The nutritional status of 59 consecutive geriatric male patients admitted to the medical service of a Veterans Administration Hospital was evaluated and compared with that of 93 younger patients admitted during the period. Protein-calorie malnutrition was diagnosed in 61 per cent of patients aged 65 or older compared with 28 per cent of patients younger than 65. The death rate and the incidence of infection were higher in the malnourished geriatric patients, however, there was no increase in the incidences of these abnormal findings compared with well-nourished patients udder the age of 65. The presence of malnutrition on admission, regardless of age, predicted a significant increase in the risk of infection or death during the hospital course.
对一家退伍军人管理局医院内科收治的59例老年男性患者的营养状况进行了评估，并与同期收治的93例年轻患者的营养状况进行了比较。65岁及以上患者中61%被诊断为蛋白质-热量营养不良，而65岁以下患者中这一比例为28%。营养不良的老年患者死亡率和感染发生率更高，然而，与65岁以下营养良好的患者相比，这些异常情况的发生率并未增加。入院时存在营养不良，无论年龄大小，都预示着住院期间感染或死亡风险会显著增加。
