COVID-19 pandemic exacerbation of disparities in access to public abortion services in Mexico

Background We describe clients in Mexico City's public abortion programme, Interrupci & oacute;n Legal de Embarazo (ILE), during the COVID-19 pandemic and test whether the pandemic exacerbated inequities in access.Methods We conducted a cohort study of all abortions in the ILE programme from 1 January 2019 to 30 June 2022. We compared patients from within and outside the Mexico City Metropolitan area (ZMVM) by pandemic stage (pre-, acute-, mid- and late-COVID periods) and assessed changes in client characteristics (adolescent age, education, weeks' gestation) by place of residence (ZMVM vs outside the ZMVM) using linear probability models clustered on state.Results We included 45 031 abortions. The proportion of abortions to women who travelled from outside the ZMVM decreased from 6.5% pre-COVID to 4.4%-4.8% in in the acute, mid- and late-COVID periods. The adjusted probability of being an adolescent who travelled from outside the ZMVM dropped between pre-COVID (14.4%, 95% CI 12.7% to 16.1%) and mid-COVID (9.3%, 95% CI 7.9% to 10.7%). The proportion of abortions to women with a high school education stayed fairly flat among those travelling, while it rose among those residing in the ZMVM. The adjusted probability of presenting at 11 gestational weeks or greater was higher among women residing in the ZMVM in the pre-pandemic period; this flipped during all pandemic stages, with a higher probability of presenting at 11 weeks or greater among those who travelled from outside the ZMVM.Conclusions The COVID-19 pandemic exacerbated existing disparities in who can access ILE services. To reduce inequities in access to essential health services, public sector abortion services should be made available in all Mexican states.
