Background
Anxiety disorders are prevalent amongst older adults and negatively impact their quality-of-life and health. Anxiety disorders often go undetected or are misattributed to age-related changes. The aim of this systematic review of reviews, was to synthesize existing evidence on risk factors associated with anxiety in older adults to improve opportunities for early detection and intervention.
Methods
A rapid systematic review of reviews was performed. Studies were included if they were systematic reviews, specific to older adults, reported modifiable or non-modifiable factors associated with increased or decreased frequency of anxiety, and reported on anxiety disorders or symptoms of anxiety (including fear of falling).
Results
27 papers met criteria for inclusion. A total of 77 unique risk and protective factors across demographic, health, environmental, and psychosocial domains were identified. Recurrently identified risk factors for anxiety included female sex, health (e.g., multimorbidity, sensory impairments), physical functions (e.g., impaired balance, history of falls), psychological factors (e.g., fear of falling, depression), social isolation, and sleep disturbances, whereas good physical health and balance confidence were protective.
Conclusions
This review reinforces the multifaceted and complex nature of anxiety in older adults. The results synthesized, highlight risk factors that should prompt detection of older adults for anxiety disorders and provide valuable insight for the development of tailored detection tools that better identify older adults at risk. Future research should address methodological limitations and include more diverse populations to improve opportunities for early detection and intervention in this vulnerable population.

背景
焦虑障碍在老年人群中高发，会对其生活质量与健康状况产生负面影响。焦虑障碍常被漏诊，或被错误归因于年龄相关的生理变化。本项系统综述的系统综述（systematic review of reviews）旨在整合现有关于老年人群焦虑相关风险因素的研究证据，以提升早期识别与干预的可行性。
方法
本研究开展了一项快速系统综述的系统综述。纳入标准如下：研究类型为系统综述、研究对象为老年人群、报告了与焦虑发生频率升高或降低相关的可改变或不可改变因素、且针对焦虑障碍或焦虑症状（包括跌倒恐惧）展开分析。
结果
共计27篇文献符合纳入标准。研究最终识别出涵盖人口统计学、健康状况、环境及社会心理四大领域的77种独特的风险与保护因素。反复被证实的焦虑相关风险因素包括：女性性别、健康状况（如共病、感官功能障碍）、躯体功能（如平衡受损、跌倒史）、心理因素（如跌倒恐惧、抑郁）、社会隔离及睡眠障碍；而良好的躯体健康状况与平衡信心则为保护因素。
结论
本综述进一步证实了老年人群焦虑问题的多维度与复杂性特征。本次整合的研究结果明确了可用于提示老年人群焦虑障碍筛查的风险因素，同时为开发更精准的针对性筛查工具提供了重要参考，以更好地识别高危老年人群。未来研究应针对现有方法学局限展开改进，并纳入更多样化的研究人群，从而进一步提升这一脆弱群体的早期识别与干预可行性。
