[Prevalence of diagnosed chronic disorders in the immigrant and native population].

Objective: To estimate the prevalence rates of chronic disorders in immigrants and to compare them with those in the native population, based on electronic clinical records in primary care (ECRPC).

Methods: We performed a descriptive cross-sectional study in patients aged 16 and over included in the Madrid Regional Public Health System. Age-adjusted prevalence rates for each sex and region were estimated on the basis of medically examined cases registered in the ECRPC with any new data entry made in 2005 or 2006.
