Correlates of pregnancies ending in induced abortions: a population-based analysis from the age perspective

Induced abortions (IAs) constitute a fundamental right contributing to women's reproductive sexual health allowing them to decide whether they wish to avoid, postpone, space, or conclude their motherhood. In this study, fertility control through IA is analysed according to the age combined with the individual and contextual characteristics of the women. Data from the Voluntary Termination of Pregnancy Statistics (Ministry of Health) and the Vital Statistics (Movimiento Natural de la Población, National Statistics Institute) were combined to capture all pregnancy outcomes, including IAs, live births, stillbirths, and late foetal deaths. Binary logistic regression models were applied to each age group (15-19, 20-29, 30-39, and 40-44 years) to calculate the likelihood of opting for an abortion based on whether individuals have a partner, the number of children, and adjusted for other sociodemographic variables. In the early reproductive stages, the probability of opting for an IA was higher in women without a partner than in those with one. In contrast, in the later years of the reproductive cycle, women with two or more children were more likely to opt for an IA, indicating their desire to stop childbearing. The likelihood of opting for an IA varies according to the woman's age. Furthermore, sociodemographic characteristics within each group of age undergo significant changes. A more detailed analysis of the reasons leading to the choice of abortion is necessary. Additionally, this study serves as valuable input for family planning public policies.
