Patterns of Medication Use in the Immigrant Population Resident in Spain: Associated Factors

Purpose: This study mainly aimed at to ascertain to ascertain the prevalence of the consumption of medications, prescribed and self-medicated, among the immigrant population (economic immigrants and not economic immigrants) resident in Spain, and to identify the factors associated with such consumption in this population.

Methods: We have worked with individualized secondary data, collected in the Spanish National Health Survey carried out in 2006 and 2007 (SNHS-06), from the Ministry of Health and Consumer Affairs. A total of 2055 subjects born outside Spain, aged 16 years or over, were analysed. The independent variables were sociodemographic and health-related, and the dependent variable was medication use. Using logistic multivariate regression models we have estimated the independent effect of each of these variables on the medication consumption.

Results: The 55.8% of immigrant population responded affirmatively to having consumed some type of medication. The drugs that registered the highest consumption prevalence were analgesics (53.09%). It should be stressed here that 8.75% of the not economic immigrant population has consumed antibiotics. The variables that were independently and significantly associated with a greater probability of medication consumption were: sex, age, presence of chronic disease, use of alternative medicines and a negative perception of health. The most strongly associated variable is medical consultation.

Conclusions: The prevalence of medication use higher among economic immigrant women. In our population, the use of alternative medicines use and medical visits to the physician are associated with higher consumption.
