Impact of Social Drivers of Health on Mammogram Screening Adherence Among Women of Different Hispanic Subgroups in the United States

<b>Introduction:</b> This study addresses the diversity within Hispanic communities by examining mammogram screening adherence among various Hispanic subgroups, focusing on how social drivers of health influence adherence to United States Preventive Services Task Force (USPSTF) mammogram screening guidelines from 2010, 2013, 2015, and 2018. <b>Methods:</b> We analyzed datasets from the 2010, 2013, 2015, and 2018 National Health Interview Survey (NHIS). We included 3,120 Hispanic women aged 50-74 and assessed their demographic and health characteristics, including insurance coverage and healthcare utilization. The primary outcome was adherence to mammogram guidelines. <b>Results:</b> Health insurance significantly increased mammogram screening adherence across all Hispanic subgroups (PR 1.39, p < 0.001). For Mexican Americans, longer U.S. residency was associated with lower screening adherence (PR 0.72, p < 0.001), and among Dominicans, education beyond high school was associated with lower screening adherence (PR 0.68, p = 0.011). Consulting a general doctor in the past (PR 1.17, p < 0.001) and having a usual place to go when sick (PR 1.48, p < 0.001) were associated with mammogram screening adherence across all subgroups. <b>Conclusion:</b> Screening rates varied among subgroups but did not differ significantly, consistent with prior studies. However, inconsistencies in subgroup behaviors highlight the need for targeted healthcare interventions addressing the unique challenges of these diverse communities.
