The authors assessed anxiety and depression among nursing home and congregate housing residents at yearly intervals. At baseline, modified DSM-III-R criteria yielded a 3.5% prevalence rate for anxiety or panic disorders. Another 13.2% reported milder symptoms not meeting diagnostic criteria. Anxiety was strongly associated with depression and with physical health, functional disability, and cognitive status. Follow-up data yielded an overall incidence rate of 2.3% for possible anxiety disorders; the majority of these cases were among those with mild anxiety at baseline. Change in anxiety was strongly associated with depression and, less consistently, with functional disability and cognitive status. Results are interpreted as indicating the indistinguishability of anxiety from depression in this frail elderly population.
作者每年对养老院和集体住房居民的焦虑和抑郁情况进行评估。在基线时，采用修订后的《精神疾病诊断与统计手册》第三版修订本（DSM-III-R）标准，焦虑症或恐慌症的患病率为3.5%。另有13.2%的人报告有未达到诊断标准的较轻症状。焦虑与抑郁、身体健康、功能残疾和认知状态密切相关。随访数据显示，可能的焦虑症总体发病率为2.3%；其中大多数病例发生在基线时患有轻度焦虑的人群中。焦虑的变化与抑郁密切相关，与功能残疾和认知状态的相关性则不太一致。研究结果被解释为表明在这个体弱的老年人群体中，焦虑与抑郁难以区分。
