目的 在整体医疗实践中使用简易营养评价精法(MNA-SF)了解我院各临床科室营养不良发生的情况.方法 由经过专门训练的医务人员在患者入院3 d内,使用MNA-SF对全院各科室患者进行营养状况调查,了解营养状况与性别、年龄、病情的关系.结果 全院患者营养不良发生率为22.25%,内科、外科、专科营养不良发生率分别为28.69%、23.26%、14.46%(χ2=144.377,P=0.000),营养分值与年龄、病例分型呈负相关(Z值分别为-60.334和-33.916,P=0.000),男、女营养分值比较,差异有统计学意义(t=-6.123,P=0.000).年龄、病例分型进入了影响营养分值的逐步回归方程,回归方程为:y营养=0.004x年龄+0.099x病理分型+0.447(r=0.146,F=39.772,P=0.000).结论 营养不良发病率在住院患者达20%以上,营养与年龄、病情相关,男性患者营养状况较女性差.%Objective To investigate the malnutrition status in a hospital using Short - Form Mini - Nutritional Assessment ( MNA - SF ). Methods The well - trained medical staff used MNA - SF to investigate the nutrition status of inpatients 3 days after their admission, and the potentail correlation of nutritional status with gender, age, and disease severity were ex-plored. Results The overall malnutrition rate in our hospital was 22. 25% ; more specifically, it was 28. 69% , 23. 26% and 14. 46% in the department f internal medicine, department of surgery, and department of special services ( x2 = 144. 377 , P = 0. 000 ), respectively. In addition, the nutrition score was negatively correlated with age and disease severity ( Z = - 60. 334, -33. 916, P =0. 000 ), and showed significant difference between males and females ( t = - 6. 123 , P =0. 000 ). The score of age, pathological types were qualified for the stepwise regression equation of nutrition, which was ynutrition = 0. 004xage + 0. 099xclassification of cases + 0. 447 ( r = 0. 146, F = 39. 772, P = 0. 000 ). Conclusion The incidence of malnutrition a-mong the inpatients in our hospital is over 20% . Nutrition status can be influenced by age and disease severity. Male patients are more susceptable to malnutrition.
