Gender-Affirming Hormone Therapy and Cervical Cancer Screening Rates in Transgender Men and Nonbinary People: A Cross-Sectional Study from a Boston Community Health Center.

Purpose: Clinical monitoring for patients receiving gender-affirming hormone therapy (GAHT) has the potential to facilitate their receipt of preventive health services. We aimed to determine whether GAHT is associated with increased utilization of cervical cancer screening among transgender men (TM) and nonbinary persons assigned female at birth (NB-AFAB). Methods: We conducted a cross-sectional observational study of a single community health center in Boston. Persons of all gender identities eligible for cervical cancer screening during 2008-2019 were assessed. The outcome of interest was receipt of cervical cancer screening based on U.S. Preventive Services Task Force recommendations. We compared the proportion of persons who received cervical cancer screening by prescription of GAHT. Results: We identified 13,267 eligible persons. This cohort included 10,547 (79.5%) cisgender women, 1547 (11.7%) TM, and 1173 (8.8%) NB-AFAB persons. Among all persons eligible for cervical cancer screening, TM and NB-AFAB persons were less likely to receive screening than cisgender women (56.2% and 56.1% vs. 60.5% respectively; odds ratio [OR] = 0.84; 95% confidence interval [CI] = 0.75-0.93; OR = 0.84; 95% CI = 0.74-0.94, respectively). Among TM, those prescribed testosterone were more likely to receive cervical cancer screening than those not prescribed testosterone (57.9% vs. 48.2%, OR = 1.47; 95% CI = 1.14-1.92). Among NB-AFAB adults, those prescribed testosterone were more likely to receive cervical cancer screening than those not prescribed testosterone (61.9% vs. 51.5%, OR = 1.53; 95% CI = 1.21-1.93). Conclusions: The benefits of engagement in care to access GAHT may extend beyond the hormonal intervention to preventive health services.
