The nutritional status of 191 elderly subjects living in three types of non-acute care institutions was studied by estimating nutrient intake and biochemical status. The dietary intake of women in the long-stay institution was similar to that of free-living elderly subjects. Dietary consumption of subjects living in a private nursing home and a convalescent unit were poorer than for elderly free-living subjects. Elderly women in all institutions had a poorer protein nutritional status, a poorer biochemical status of vitamin B12, folate, ascorbic acid, and vitamin D, and lower plasma potassium levels when compared with free-living elderly women. Those in the private nursing home and the convalescent unit had the poorest protein nutritional status. Among men, institutionalized subjects were observed to have poorer thiamine and riboflavine status, in addition to the above findings. The greater prevalence of chronic diseases and disability in the convalescent unit and the private nursing home may partly account for the poorer nutritional status of residents in these two institutions.
通过评估营养摄入量和生化状况，对居住在三类非急性护理机构中的191名老年受试者的营养状况进行了研究。长期居住机构中女性的饮食摄入量与自由生活的老年受试者相似。居住在私立养老院和康复机构的受试者的饮食消费比自由生活的老年受试者差。与自由生活的老年女性相比，所有机构中的老年女性蛋白质营养状况较差，维生素B12、叶酸、抗坏血酸和维生素D的生化状况较差，血浆钾水平较低。私立养老院和康复机构中的老年女性蛋白质营养状况最差。在男性中，除上述发现外，还观察到机构化受试者硫胺素和核黄素状况较差。康复机构和私立养老院中慢性病和残疾的患病率较高，这可能部分解释了这两个机构中居民营养状况较差的原因。
