目的 探讨运用不同的营养评价方法评价住院老年患者的营养状况并分析其相关的影响因素，为进一步合理有效 地对老年住院患者进行营养治疗提供科学依据。方法  选取我院2017 年 4 月至2018 年 4 月住院接受治疗的210 例老年患 者作为研究对象，运用微型营养评定简版、体质指数、小腿围及血清白蛋白水平来评价老年住院患者的营养状态，比较分 析相关影响因素对老年患者营养状况的影响。结果  微型营养评定简版、体质指数、小腿围及血清白蛋白水平评价出的营养 状况正常者的比例分别为40.48%、42.86%、78.57% 和 79.52%。在微型营养评定简版、小腿围及血清白蛋白方面，年龄段 ≥ 85 岁与 65~74 岁和 75~84 岁年龄段住院老年患者比较存在差异显著，具有统计学意义（P ＜ 0.05）；自身营养关注度： 关注组与一般关注组住院老年患者微型营养评定及血清白蛋白比较，具有统计学意义（P ＜ 0.05）；很关注组与不关注组 住院老年患者指标之间比较，具有统计学意义（P ＜ 0.05）。日常生活活动能力：在微型营养评定简版、体质指数、小腿 围及血清白蛋白方面，基本或完全自理与需要帮助、明显或完全依赖比较，具有统计学意义（P ＜ 0.05）。结论 营养不良 在老年住院患者中所占的比例较高，营养评价结果受年龄、文化程度、自身营养关注度及日常生活活动能力影响，通过健 康宣教、体能锻炼来提高患者对自身营养的关注度和日常生活活动自理能力，可以帮助老年住院患者改善营养状况。

Objective To evaluate the use of different nutrition evaluation methods to evaluate the nutritional status of elderly patients in hospital and analyze the related influencing factors, to provide a scitific basis by taking tnterventons improve the health of the elderly. Methods Selected 210 elderly patients in Beijing shijitan Hospital from April 2017 to April 2018 as the research objects. The nutritional status was evaluated by MNA-SF, BMI, CC, ALB levels, to analysis of the influence of related factors on the nutritional status of elderly patients. Results The rates of good nutrition were 40.48%, 42.86%, 78.57% and 79.52% respectively in MNA-SF, BMI, CC and ALB levels. In terms of MNA-SF score, CC, and ALB, there was a significant difference in the age group≥85、6574 years old and 75-84 years old in the elderly patients with statistical significance (P<0.05); Self-nutritional attention: The attention group compared MNA-SF score and ALB in elderly patients with general concern group with statistical significance (P<0.05); In terms of MNA-SF score, BMI, CC, and ALB, there is a statistical significance between the group of concern and the group of inpatient elderly patients (P<0.05). Daily life activity ability: In MNA-SF score, BMI, CC, and ALB, basic or complete self-care is statistically significant compared with the need for help, obvious or complete dependence (P<0.05). Conclusions Malnutrition accounts for a high proportion of elderly inpatients, and the nutritional evaluation results are influenced by age, educational level, self-nutritional attention and ability of daily activities. Health education and physical exercise to improve the patient's attention to their own nutrition and daily activities self-care ability, can help elderly inpatients improve nutritional status.
