RESUMO
OBJECTIVES: The literature has been conceptualizing pregnancy occurrence as a multiphase event. However, the different combinations of decisions and behaviors leading to pregnancy that end in abortion remain unexplored in the literature. The aims of the study were to describe the reproductive and relational trajectories leading to pregnancy in women who decide to abort and to explore the differences in this process according to women's age [adolescents (<20 years old) vs. adults]. STUDY DESIGN: In this cross-sectional study, 426 women [246 adolescents (58.4%), 177 adults (41.6%)] who chose abortion were recruited. Data on reproductive and relational characteristics were collected through a self-report questionnaire at 16 healthcare services that provide abortion. The variables were introduced in trajectories according to the criterion of temporal sequence between them: age at first sexual intercourse, relationship type, pregnancy planning, use of contraception, identification of contraceptive failure, and occurrence of pregnancy. RESULTS: Seven trajectories leading to pregnancy were identified. The most frequent trajectory (30.8%) included women who 1) were involved in a long-term romantic relationship, 2) did not plan the pregnancy, 3) were using contraception, and 4) did not identify the contraceptive failure that led to pregnancy. Although this was the most frequent trajectory for both age groups, the remaining trajectories showed a different distribution. Compared to adolescents, adult women's trajectories more frequently included casual relationships with non-use of contraception, or contraceptive use with no contraceptive failure identification. CONCLUSION: Our study highlights the need to recognize the multiplicity of reproductive and relational trajectories leading to pregnancies that end in abortion and their specificities according to women's age. These findings have important implications for abortion counselling and for the development of age-appropriate guidelines for preventive interventions, by drawing attention to prioritization of different contexts of intervention according women's age.
