RESUMO
BACKGROUND AND OBJECTIVES: The socioeconomic position of women who have an induced abortion has been explored extensively, but without taking contextual factors into account. The objective was to describe socioeconomic inequalities in the rate of induced abortion in Spain in 2001, jointly evaluating the effects of both regional and individual socioeconomic characteristics. METHODS: A cross-sectional study using a multilevel approach was carried out among women who were resident in Spain in 2001, considering the hierarchical structure of relevant factors. Analyses were carried out at the individual and regional level. We fit Poisson regression models to calculate adjusted relative risks (aRR) of induced abortion and 95% confidence intervals (CIs). RESULTS: The estimated abortion rate was 6.26 per 1000 women aged 20-49 years. Induced abortion was more frequent among younger women (aRR = 1.55 for women aged 20-24 years, compared with those aged 25-34 years) and those with less than primary education (aRR = 2.25 compared with women with university studies). Women residing in regions with lower public spending on non-university education (aRR = 0.83, 95% CI: 0.70-0.98) and a higher percentage of non-European Union immigrants (aRR = 1.06, 95% CI: 1.02-1.10) were also more likely to have had an induced abortion. CONCLUSIONS: Socioeconomic inequalities in the practice of induced abortion in Spain exist not only at the individual level but also at the regional level. The prevention of unintended pregnancy should be approached using a global political strategy aimed at changing contextual and individual factors that contribute to unintended pregnancy.
