老年卧床管饲患者营养状况分析

目的：对住院的老年卧床管饲患者进行营养状况调查。方法：对78例管饲时间半年以上的卧床(年龄63～97岁)男性患者进行摄入量计算、人体测量和观察生化指标。结果：混合型营养不良患者合并肺内感染的发生率最高为89．5％，低蛋白血症型患者合并肺内感染占76．7％，而消瘦型营养不良患者合并肺内感染仅占10．3％。相关分析表明，混合型和低蛋白血症型营养不良的老年患者的蛋白质需要量增加；多因素逐步Logistic回归分析表明，合并肺部感染的OR值为11．88。结论：年龄和肺部感染是老年卧床患者低白蛋白血症的主要危险因素，肺部感染是强危险因素。

Nutritional status of elderly bed-ridden patients with tube feeding

Objective:To evaluate the nutritional status and related to factors hypoalbuminemia in the elderly bed-ridden patients with tube feeding. Methods:78 male elderly bed-ridden patients with tube feeding over half years were studied. Anthropometric and loboratory variables and dietary intake were investigated. Results:The complications of lung infection were 89.5%, 76.7% and 10.3% in Marasmic-Kwashiorkor, hypoalbuminemia and Marasmus patients, respectively. Marasmic-Kwashiorkor and hypoalbuminemia have more protein requirements. By multivariate logistic regression analysis, odds ratios for hypoalbuminemia of complication of lung infection were 11.88.Conclusions:Older age and complication of lung infection are risk factors associated with hypoalbuminemia in elderly bed-ridden patients. But lung infection is major risk factor in these patients.
