Objective: To try to find out the morbidity of elderly chronic pulmonary disease's malnutrition by means of MNA and analyze the consistency between traditionalindex and MNA score. Methods: According to the score of MNA,we divided the 143 elderly pulmonary disease patients into three groups: A group(malnutrition); B group(malnutrition risk);C group(well nourished).The records included anthropometry,biochemical markers,dietary intake as well as the occurrence rate of pneumonia and respiratory failure. Results: There were marked differences on anthropometry,biochemical markers,dietary intake and the occurrence rate of pneumonia and respiratory failure among three groups. And the dietary intake of all three groups did not reach the standard of normal people. Conclusion: MNA is a good method that can be used to evaluate the nutritional state in elderly pulmonary disease patients.
