title: [Healthy Life Years: a very promising indicator to be handled with caution].
abstract: In several public debates, scientific conferences and, recently, also in the scientific literature, some figures from EUROSTAT have been presented; they show a relevant decrease in the healthy life expectancy in Italy. This idea is based on the analysis of the trend of Healthy Life Years (HLY), an indicator synthesizing the grade of functional limitation of individuals based on the answers to a self-completed questionnaire. In particular, the dramatic decrease of HLY in Italy from 2005 to 2007 raised concerns. This paper analyses the reasons suggesting caution in interpreting these data considering first and foremost the changes across years in the formulation of questions and answers. Even though HLY and the other indicators selected by the European Union have a great potential in terms of communication and synthetic view, caution is needed in using these data and in drawing conclusions from figures and instruments of recent application that are still evolving.
