La misura delle differenze etniche nella salute - During the last ten years the number of immigrants has rapidly risen in Italy, reaching almost the 6% of the total population. Immigrants come from more than 190 different countries and their health is a crucial capital to enter the labour market, where they play an important role, even if the achievement of social integration is still a challenge. As the monitoring of immigrants health status is an important mean to plan the actions to tackle health inequalities and to improve their health conditions, it is necessary that the National Health System develops a common methodology and produces some shared indicators to perform it. To achieve this aim a national board on the project Promoting immigrants health in Italy has been established and it is now working to find the sources of data and a reduced number of useful health indicators, measurable all around the Country. This paper presents a summary of the main informations provided by the board up to now. Keywords: immigrants, health, socio-economic status, pregnancy, indicators, epidemiology. Parole chiave: immigrati, salute, condizione socio-economica, gravidanza, indicatori, epidemiologia.
