Inequalities in induced abortion according to birthplace and educational attainment in a Southern European region (Basque Country)
The study was a cross-sectional population-based study including IA of women aged 25-49 years residing in the Basque Country, Spain, between 2011 and 2013. Prevalence estimates and log-binomial regression were used to quantify the effects of birthplace and education attainment on all outcomes.
The results indicate that immigrant women exhibited higher probability of having an IAs (PR:5.31), repeated (PR:7.23) and 2nd trimester IAs (PR:4.07) than Spanish women. For educational attainment, we found a higher probability in all outcomes among women with a primary or lower education relative to those with a graduate education (All IA PR:2.51; repeated IA PR:6.00; 2nd trimester IA PR:3.08). However, no heterogeneity was observed for the joint effect birthplace and educational attainment on IAs, repeated and 2nd trimester IAs.
This study called attention to the importance of birthplace and educational level as key factors explaining not only an IA decision but also having a repeated IA or a 2nd semester IA and suggest a better understanding of these factors when designing programs for sexual and reproductive health education to reduce inequalities between women.
