[Health status and anxiety in the elderly. A longitudinal perspective].

The prognostic value of physical health for changes in anxiety symptoms in older people was investigated in a prospective longitudinal study design with data from the Longitudinal Aging Study Amsterdam (LASA). In a sample of 2165 older (> 55 yrs.) respondents anxiety symptoms were measured twice over a three year interval with the anxiety subscale of the Hospital Anxiety and Depression Scale (HADS-A). Utilizing a cut-off value of 4 on the HADS-A, subjects were considered as anxious or as non-anxious. Based on the first assessment two groups were formed: subjects with and subjects without anxiety symptoms. In the non-anxious cohort the effect of physical health on the development of anxiety symptoms was studied; in the anxious cohort the same factors were evaluated on their predictive value for chronicity of anxiety. Indices of physical health included the presence of chronic diseases, functional limitations, and self-perceived health at the first assessment and changes on these variables over time. Results revealed that poor self-perceived health was predictive of incidence (OR = 1.5; 95% CI = 1.3-1.8) and chronicity of anxiety (OR = 1.2; CI = 1.0-1.5). Regarding chronic diseases, the results showed that suffering from more than one chronic disease predicted becoming anxious and chronicity of anxiety (OR = 1.7; CI = 1.2-2.5 and OR = 2.2; CI = 1.3-3.6, respectively). Specific chronic diseases were not strongly related to a change in anxiety levels. Thus, somatic diseases not only lead to depression, a finding reported in numerous studies, but also increase the likelihood of anxiety symptoms at a later point in time.
