Differentiating middle-aged long-term and short-term frequent attenders by means of the Northern Finland Birth Cohort 1966 Study.

Middle-aged long-term FAs and short-term FAs have distinct characteristics; namely, depression and high income differentiate long-term FAs from short-term FAs. Poor self-reported health was associated with long-term FAs in particular. In order to identify FAs with prolonged service needs and to develop far-reaching interventions, the focus of research should be on long-term FAs.
