Prevalence of Nutritional Risk, Undernutrition, Overweight/Obesity and Application of Nutritional Support Among Geriatric Patients at Peking University People's Hospital

摘要

Objective To investigate the prevalence of nutritional risk,undernutrition,overweight/obesity,and the application of nutritional support among geriatrics so as to provide evidence for whether elderly inpatients with undernutrition and nutritional risk should receive timely nutritional support.Methods A total of 445 elderly inpatients in the Department of Geriatrics of Peking University People's Hospital were consecutively enrolled from July 2010 to June 2011.The Nutritional Risk Screening 2002 (NRS 2002) questionnaire was used on the second day after admission.The application of nutritional support was investigated on the 14th day or the discharge day.The relationship between the nutritional risk and nutritional support was analyzed.A NRS 2002 score ≥ 3 was defined as nutritional risk.A body mass index (BMI) ＜ 18.5 kg/m2 was defined as malnutrition,24.0 kg/m2 ≤ BMI ＜ 28.0 kg/m2 as overweight,and a BMI ≥ 28.0 kg/m2 as obese.Results A total of 445 patients were enrolled and 423 patients (95.1％) completed the NRS 2002.The prevalence of undernutrition and nutritional risk was 4.7％ and 13.2％,respectively.Among 230 patients who were overweight/obese,the prevalence of nutritional risk was 6.1％.In total,15 of the 56 patients (26.8％) with NRS 2002 scores ≥ 3 received nutritional support,and 14 patients (3.8％) with NRS 2002 scores ＜ 3 also received nutritional support.The average PN∶ EN ratio was 1.6∶1.Conclusion A certain proportion of elderly inpatients in the department of geriatrics were experiencing undernutrition or were at nutritional risk.The prevalence of nutritional risk did not increase significantly with age.The current application of nutritional therapy is inappropriate.Evidence-based guidelines are required to improve this situation.The NRS 2002 may not applicable for overweight/obese elderly inpatients.
