An assessment of protein-calorie status was performed on 200 consecutive adult nonobstetric admissions to a private hospital from two group family practices. Anthropometric measurements, serum albumin level, and total lymphocyte count were determined at admission and weekly if the patient remained in the hospital. Nonnutritional factors affecting muscle protein stores and serum albumin level were taken into account. A total of 63 patients (31.5%) were found to be malnourished. The most common conditions associated with decreased protein stores were hypoxic cardiopulmonary disease, gastrointestinal disease, neuromuscular or arthritic impairment, organic brain syndrome, and febrile illness. Although nonnutritional factors accounted for many instances of protein depletion, expecially milder degrees of depletion, nevertheless protein calorie malnutrition was highly prevalent in this population.
对来自两个集团家庭诊所的200名连续入住一家私立医院的成年非产科患者进行了蛋白质 - 热量状况评估。入院时测定人体测量指标、血清白蛋白水平和总淋巴细胞计数，若患者仍住院则每周测定一次。考虑了影响肌肉蛋白质储备和血清白蛋白水平的非营养因素。共发现63名患者（31.5%）营养不良。与蛋白质储备减少相关的最常见疾病是缺氧性心肺疾病、胃肠道疾病、神经肌肉或关节炎损伤、器质性脑综合征和发热性疾病。尽管非营养因素导致了许多蛋白质消耗的情况，尤其是轻度消耗，但蛋白质热量营养不良在该人群中仍然非常普遍。
