Risk factors, awareness of disease and use of medications in a deprived population: differences between indigent natives and undocumented migrants in Italy.

Undocumented migrants experience many health problems; a comparison with a suitable control group of natives living in the same socio-economic conditions is still lacking. Demographic data and data on risk factors, chronic conditions and dietary habits were obtained for 6933 adults (2950 Italians and 3983 undocumented migrants) receiving medical assistance from 40 non-governmental organizations all over the country. Attributed to the fact that these were unselected groups, differences were found in their demographic features, the main ones being their marital status (singles: 50.5% among Italians and 42.8% among migrants; P < 0.001). Smokers were more frequent among Italians (45.3% versus 42.7% P = 0.03); the same happened with hypertension (40.5% versus 34.5% P < 0.001). Migrants were more often overweight (44.1% versus 40.5% P < 0.001) and reporting a chronic condition (20.2% versus 14.4% P < 0.001). Among those on medications (n = 1354), Italians were fewer (n = 425) and on different medications. Differences emerged also in dietary habits. Differences in health conditions exist between native-borns and undocumented migrants, not because of a bias related to socio-economic conditions. Further studies are needed to design sustainable health policies and tailored prevention plans.
