[Factors associated to medical visits: comparison among Italians and immigrants resident in Italy].

OBJECTIVES: to evaluate the role of factors potentially associated with the use of medical visits by the immigrant population living in Italy, making a comparison with the Italian population.

DESIGN: cross-sectional study based on the representative sample of the population residing in Italy considered in the Survey "Health and use of health services" conducted by the Italian National Institute of Statistics (Istat) in 2013.

SETTING AND PARTICIPANTS: the study was conducted on a sample of citizens aged 18-64 years (72,476 individuals) representing a population of 37,290,440 residents in Italy (33.9 million Italians and 3,390,440 foreigners) in 2013.

MAIN OUTCOME MEASURES: an indicator on the use of medical visits has been used as an outcome, based on people who had replied affirmatively to the question: «In the last four weeks, have you been examined by the family doctor, by the pediatrician, or by medical specialists, as an eye doctor, dentist, etc.?». Starting from this outcome, the question «Can you indicate the main reason of the visits made in the last 4 weeks?» was used to build two additional outcome variables for separately evaluating the use of medical examinations for "diseases or disorders" from the use of medical examination for "health check in the absence of diseases or disorders". For each outcome, a logistic regression model was fitted, considering as independent variables information related to socioeconomic status and to the respondent's health condition.

RESULTS: 21.4% of foreigners (18-64 years) living in Italy used medical visits during the four weeks before the interview, a percentage lower than the one recorded among Italian citizens (27.0%). Taking into account the socioeconomic characteristics, lifestyle and health status of respondents, the results of logistic regression models showed that foreigners have a lower probability than Italians to make a medical examination, both for visits motivated by any health problems (OR: 0.80; 95%CI 0.73-0.87), and in case of medical examination carried out for preventive purposes (OR: 0.72; 95%CI 0.64-0.82).

CONCLUSION: the more the time living in the host Country increases, the more immigrants residing in Italy tend to have the same health problems of the most disadvantaged groups of the autochthonous population, maybe beacuse of the deterioration of the so-called "healthy immigrant effect". In this context, they should be considered as more vulnerable in terms of health, and special attention must be paid to prevention. The lower use of medical visits highlights inequities in access to services. In order to reduce health inequalities, barriers that affect equitable access to health care should be removed, taking into account the heterogeneity of these sub-groups, characterized by different cultures and attitudes towards the health system.
