Discovering unhealthiness: evidence from cluster analysis Summary Purpose This study exploits information on an array of health limitations, chronic conditions, treatments and drug consumptions to reveal the prevalence and severity of unhealthiness

Results Among the study participants, 8% of those age 45-54, 10% of those age 55-64, 13% of those age 65-74 and 17% of those age 75 and over were classified as unhealthy. For the youngest individuals, unhealthiness is characterized by moderate to high mental distress, a poor physical health score equivalent to the score associated with having four major limitations in physical functioning, teeth health less than good, and having been diagnosed with at least two chronic conditions. The oldest individuals also suffer from these limitations, as well as dependence on at least three different drug groups and two medical treatments, but they are in better mental health state.
