Vulnerability to experiencing an unintentional pregnancy among women who use the Unified Health System

Objective: To analyze the vulnerability to experience an unintentional pregnancy among women users of Primary Care Centers and the associated aspects. Methods: A cross-sectional study with a total of 470 women users of Primary Care Centers of the East Health Supervision Department from the city of Sao Paulo. Data were collected through interviews and multiple logistic regression was used to analyze the associated aspects. Results: Approximately half of the women were found to be vulnerable to experiencing an unintentional pregnancy (48.3%). Women aged 25 to 34 years old were more likely to be vulnerable to unintentional pregnancy compared to women aged 18 to 24 years old (OR=2.0; 95%CI 1.2-3.4), the same observed for women aged 35 years old or older (OR=9.7; 95%CI 5.3-17.6). Women in a stable relationship were less likely to be vulnerable to an unintentional pregnancy compared to single women (OR=0.4; 95%CI 0.3-0.7). Women who did not plan a previous pregnancy were more likely to be vulnerable to an unintentional pregnancy compared to women who planned a previous pregnancy (OR=2.5; 95%CI 1.2-5.1), unlike women who never got pregnant (OR=0.4; 95%CI 0.2-0.7). Conclusion: A significant portion of women was vulnerable to experiencing an unintentional pregnancy. The aspects associated with experiencing this pregnancy were age, not being in a stable relationship and not having planned the last pregnancy.
