Objective: To identify socio-demographic factors associated with presenting for abortion services past the gestational age (GA) limit (12 weeks), and thus not receiving services, in Mexico City’s public sector first trimester abortion program. Methods: We used clinical data from four high volume sites in the Interrupción Legal de Embarazo (ILE) program, 2007–2015. We used descriptive statistics to quantify the proportion of women who did not receive an abortion due to presenting past the gestational age limit. We used multivariable logistic regression to identify associations between women’s characteristics and presenting past the GA limit and calculated predicted probabilities of late presentation for key characteristics. Results: Our sample included 52,391 women, 8.10% (n = 4,246) of whom did not receive abortion services due to presenting past the GA limit. Adolescents (12–17) made up 8.69% of the total sample and 13.40% of those presenting past the GA limit (p< 0.05). In multivariable analyses, all age groups of adult women had significantly lower odds than adolescents of presenting past the limit (aOR = 0.77, aOR = 0.63, aOR = 0.58 and aOR = 0.37 for 19–24, 25–29, 30–39, and > = 40 years’ old respectively). Women living in Mexico City and with higher levels of education had lower odds of presenting past the GA limit, and there was an educational gradient across all age groups. In the multivariable predicted probability models, adolescents at every level of education have significantly higher probabilities of not receiving an abortion due to presenting past the gestational age limit compared with adults (among women with a primary education: 11.75% adolescents vs. 9.02–4.26% across adult age groups). Conclusions: Our results suggest that continued efforts are needed to educate women, especially younger and less educated women, about early pregnancy recognition. In addition, all women need information about the availability of first trimester legal abortion to ensure timely access to abortion services. [ABSTRACT FROM AUTHOR]

Objectives: In the Mexico City Metropolitan Area, only women in the city center have local access to legal first-trimester abortion. We quantify how this legislative discrepancy affects access to legal, public-sector abortion across the metropolitan area.Study Design: In this observational study, we used a dataset representing 67.2% of all abortions occurring between 2010 and 2012 in Mexico City's public abortion program and census population data. We calculate utilization rates for 75 municipalities in the metropolitan area for 2010-2012. We compare utilization between municipalities with and without local legal access, adjusting for differences in sociodemographic drivers of abortion demand. We explore the effects of local abortion legality, travel time and socioeconomic status (SES).Results: Women who had to travel into the city center for legal abortions used services at only 18.6% (95% CI 13.3%-33.0%) of the expected rate if they had local access, adjusting for sociodemographic factors. After controlling for travel time and SES, women who lived where abortion is illegal had a 58.6% (95% CI 21.5%-78.1%) reduction in access, and each additional 15 min of travel further reduced access by 33.7% (95% CI 18.2%-46.3%). Women who travel to seek legal abortions are more likely to have completed secondary education compared to other reproductive age women in their municipality (p = <.00001).Conclusions: We find that, in the Mexico City Metropolitan Area, both living where abortion is illegal and having to travel further to access services substantially reduce access to legal, public-sector abortion. These burdens disproportionately affect women of lower SES.Implications: Both local legality and proximate access are key to ensuring equity in access to public-sector abortion. Legalization of abortion services across the greater Mexico City Metropolitan Area has the potential to increase equity in utilization and meet unmet demand for legal abortion. [ABSTRACT FROM AUTHOR]
