Differences in shared decision-making and prostate cancer screening by sexual orientation and race/ethnicity.

Abstract

10525 Background: There are well-documented disparities among racial and sexual minorities in prostate cancer screening uptake and shared-decision making (SDM) conversations. However, it is unclear how racial/ethnic identity and sexual orientation interact to affect prostate-specific antigen (PSA) testing uptake. Methods: Data came from the 2018-2022 Behavioral Risk Factor Surveillance Survey (BRFSS). Outcomes were survey responses to questions about engagement in SDM and PSA testing uptake. The sample included 88,365 heterosexual (HS) men and 2,562 sexual minority (SM) men ages 55 to 69. Data were stratified by race/ethnicity and survey-weighted logistic regression models analyzed the association between sexual orientation and outcomes. Models controlled for age, relationship status, education, household income, insurance status, having a usual source of care, and region. Results: White SM men were more likely to have discussed disadvantages of PSA testing with their healthcare provider [odds ratio (OR)=1.407; p<0.001] and to have undergone PSA testing [OR=1.320; p<0.001] compared to White HS men. Asian SM men were more likely to have had discussions about PSA testing [OR=4.470; p<0.05]; to have discussed advantages [OR=4.596; p<0.05]; to have been recommended PSA testing [OR=4.836; p<0.05] and to have undergone PSA testing [OR=4.401; p<0.001] compared to Asian HS men. Black SM men were more likely to undergo screening because of an issue or a reason besides routine screening [OR=1.073, p<0.05] compared with Black HS men. Hispanic SM men were more likely to have undergone screening as part of a routine checkup [OR=4.2, p<0.001] compared with Hispanic HS men. There were no sexual orientation differences in PSA screening or SDM among American Indian or Native Alaskans. Conclusions: Differences in PSA testing uptake and SDM by sexual orientation vary by race/ethnicity. Further research is needed to study the factors affecting PSA testing uptake and SDM among sexual minority men of different racial/ethnic groups. [Table: see text]
