[The Istat National Health Interview Surveys for immigrant population]

The Istat "National Health Interview Surveys" (NHISs; 2005 and 2013) and the ad hoc interview surveys "Social conditions and integration of foreign citizens in Italy" (2011-2012) offer a wide range of information about health conditions and accessibility to health services of immigrants in Italy. NHIS, in particular, based on samples of about 60,000 families for a total of almost 120,000 individuals, allows to analyse changes in health conditions over the years and to make comparative analyses between foreign citizens and Italians. The survey "Conditions and social integration of foreign citizens", carried out on a national sample of about 10.000 households with at least one resident foreign citizen (more than 20,000 individuals), for the first time in Italy gives the chance to lead in-depth analyses in terms of health and social integration of foreigners. It also allows to study the relationships between indicators, distinguishing against major nationalities, thorugh explanatory models.
