abstract: 'Research participation among vulnerable populations is often limited by the same socioeconomic factors that contribute to poor health. Identifying best practices for inclusion is critical to addressing health disparities. Urban public housing communities bear a disproportionate burden of chronic disease and may represent an opportunity to directly engage historically vulnerable populations in research designed to ultimately reduce that burden. We used mixed-method data to analyze recruitment effectiveness among a random sample of households (N = 380) across two public housing developments in Boston, MA who were approached for participation in a pre-COVID oral health study. Quantitative data from detailed recruitment tracking methods was analyzed to assess the relative efficiency of the methods employed. Field journals of study staff were qualitatively analyzed to identify community-specific recruitment barriers and facilitators. The participation rate among randomly sampled households was 28.6\% (N = 131), with participation from primarily Hispanic (59.5\%) or Black (26\%) residents. Door-to-door knocking with response yielded the highest participation (44.8\%), followed by responses to informational study flyers (31\%). Primary barriers to enrollment included references to unemployment and employment variations, shift work, childcare responsibilities, time demands, and managing multiple appointments and social services. This study finds active, door-to-door knocking and return visits resolved barriers to participation, and reduced safety concerns and historic distrust. It''s time to consider how best to adapt effective pre-COVID recruitment practices for utilization under current and future exposure conditions as effective recruitment of populations such as urban public housing residents into research is only becoming more important.' affiliation: 'Heaton, B (Corresponding Author), Boston Univ, Henry M Goldman Sch Dent Med, Dept Hlth Policy \& Hlth Serv Res, 560 Harrison Ave,3rd Floor,Rm 329, Boston, MA 02118 USA.
