BACKGROUND Distal radius fractures (DRF) are common in the elderly and are typically caused falls. Malnutrition has also been identified as a poor prognostic factor in elderly patients with fractures. However, the relationship between nutritional status and subsequent falls and functional prognosis for DRF in the elderly is not clear. The aim of the present study was to investigate the association between nutritional status and functional prognosis in elderly patients with DRF. METHODS Study participants included 229 outpatients who required surgical treatment for DRF. The patients' clinical information, including age, sex, body mass index, bone mineral density, geriatric nnutritional risk index (GNRI), total number of drugs being treated with on admission, use of drugs for osteoporosis, comorbidity severity, the Barthel Index (BI), presence of subsequent falls, fracture type, postoperative follow-up period, and Mayo wrist score was reviewed. Subjects were further divided into two groups according to their GNRI: the malnutrition group and the normal group. Propensity score matching was used to confirm factors affecting the BI and subsequent falls. RESULTS Thirty-one patients (13.5%) presented with malnutrition before surgery for DRF. According to multiple liner regression analysis, the GNRI positively affected the efficiency of the BI (β = 0.392, 95% confidence interval [CI], 0.001 to 0.351, p = 0.039). Furthermore, on logistic regression analysis, subsequent falls were associated with serum albumin levels (odds ratio = 0.033, 95% CI, 0.002 to 0.477, p = 0.012). CONCLUSION Malnutrition impaired improvement of activities of daily living (ADL) and increased the incidence of subsequent falls. Improvement of nutritional status before DRF surgery may further improve ADL and prevent falls.

老年radius骨远端骨折患者的营养状况和功能预后：一项回顾性队列研究。

背景技术Dis骨远端骨折（DRF）在老年人中很常见，并且通常是导致跌倒的原因。营养不良也被认为是老年骨折患者的不良预后因素。但是，营养状况和随后的跌倒与老年人DRF功能预后之间的关系尚不清楚。本研究的目的是调查老年DRF患者的营养状况与功能预后之间的关系。方法研究参与者包括229名需要手术治疗DRF的门诊患者。患者的临床信息包括年龄，性别，体重指数，骨矿物质密度，老年营养风险指数（GNRI），入院时正在接受治疗的药物总数，用于骨质疏松症的药物使用，合并症的严重程度，Barthel指数（双），回顾了随后跌倒的存在，骨折类型，术后随访时间和Mayo手腕评分。根据受试者的GNRI将其进一步分为两组：营养不良组和正常组。倾向得分匹配用于确认影响BI和随后跌倒的因素。结果31例（13.5％）患者在DRF手术前出现营养不良。根据多重线性回归分析，GNRI对BI的效率产生积极影响（β= 0.392，95％置信区间[CI]，0.001至0.351，p = 0.039）。此外，在逻辑回归分析中，随后的下降与血清白蛋白水平相关（赔率= 0.033、95％CI，0.002至0.477，p = 0.012）。结论营养不良损害了日常生活活动能力，并增加了随后跌倒的发生率。DRF手术前营养状况的改善可进一步改善ADL并预防跌倒。
