Abstract: Objective To explore the effects of personalized nutrition intervention on lung function and immune status in the elderly patients with chronic obstructive pulmonary disease (COPD)and malnutrition risk. Methods A total of 128 elderly COPD patients with malnutrition risk screened by Nutrition Risk Screening 2002(NRS 2002) score were divided into the personalized nutrition intervention group and the control group according to random number table method,with 64 cases in each group.The personalized nutrition intervention group was given individualized nutrition treatment,and the control group was given routine nutrition guidance.The indexes of nutritional status, lung function, exercise tolerance and immune status were observed and compared after 3 months of treatment. Results After treatment, the indexes of nutritional status, lung function, exercise tolerance and immune status in the individualized nutrition intervention group were all significantly improved compared with those before treatment(P<0.05), and showed significant difference with those in the control group(P<0.05).The indexes of nutritional status and immune status in the control group were significantly improved after treatment(P<0.05),while there were no significant difference in the lung function and exercise tolerance(P>0.05). Conclusions Individualized nutritional intervention can improve nutritional status, enhance lung function and exercise tolerance, and restore immune status in the elderly COPD patients with the risk of malnutrition.
