精神分裂症住院患者的脆弱性很常见,并且与跌倒有关. 较高的无脂肪质量可能会减少脆弱性,而缓慢是主要的跌倒风险因素.
科学领域:
- 老年医学 老年医学
- 精神病学研究 精神病学研究
- 营养科学 营养科学
背景情况:
- 在精神分裂症患者中,越来越多地认识到脆弱性.
- 虚弱与不良结果有关,包括跌倒.
- 在精神病医院住院患者中,身体构成,虚弱和跌倒风险之间的机制尚未完全理解.
研究的目的:
- 检查精神分裂症住院患者中无脂肪质量和脆弱性之间的关联.
- 为了调查脆弱和跌倒史之间的关系.
- 为了确定最强烈地与此种人群中跌倒相关的脆弱组件.
主要方法:
- 对195名患有精神分裂症或精神分裂情绪障碍的住院成年人 (≥40岁) 的横截面研究.
- 使用日本版本的心血管健康研究 (J-CHS) 标准评估的脆弱性.
- 通过生物电阻分析测量身体成分,以计算无脂肪质量指数 (FFMI) 和脂肪质量指数 (FMI).
主要成果:
- 虚弱的发病率为32.8% (虚弱前54.9%,强壮12.3%).
- 较高的FFMI独立地与较低的脆弱率有关.
- 脆弱性强烈预测了跌倒史 (OR = 9.85),而缓慢 (步行速度降低) 是与跌倒有关的最重要的组成部分.
结论:
- 精神分裂症住院患者的脆弱性非常普遍,是跌倒风险的强有力的预测因素.
- 缓慢 (步行障碍) 是主要的脆弱组成部分,导致跌倒风险.
