[Health and its determinants in the immigrant population of the region of Madrid]

Objectives: To describe health status and its determinants in immigrants living in the region of Madrid and to compare these factors with those in the native-born population.

Material and methods: We performed a descriptive, cross-sectional study based on data from the Madrid Regional Health Survey 2007 (n=12,190). Subjects were classified as native-born or immigrants born in medium-to-low-income countries and with less or more than 5 years of residence in Spain. The results were adjusted for age. Proportions and means were compared through the ji square test and linear regression.

Results: Compared with native-born residents, immigrants were younger, carried out mainly precarious manual jobs that did not match their educational level and had a lower income and less space in their dwellings. Both immigrant men and women smoked and drank less, but women showed a higher prevalence of overweight (10% more) and physical inactivity. Adherence to smear test and blood pressure screening was up to a 16% lower. Attendance at primary care and emergency facilities was less frequent in men and women with less residence time than in those with longer residence in Spain. Self-perceived health and mental health were worse in women with 5 or more years of residence. Chronic diseases were similar in both populations but were less prevalent in immigrants.

Conclusions: Immigrants' health status is not as unfavorable as could be expected from the higher prevalence of harmful determinants of health.
