Introduction: The existing literature on colorectal cancer-related inequities among Hispanic/Latino men may be poorly descried as most outcome data to date for this ethnic group are reported in aggregate. This study explored how masculine beliefs may influence colorectal cancer screening participation among ethnic subgroups of Hispanic/Latino men aged 45-75 years.

Methods: Utilizing a consumer panel, self-identified Hispanic/Latino men that were age-eligible for colorectal cancer screening and fluent in either English or Spanish were recruited from Florida, New York, and Texas (February-March 2022). The Masculinity Barriers to Medical Care (MBMC) scale, comprising six theoretically derived subscales, was assessed masculinity. Multivariable logistic regression was employed to estimate the association between MBMC and colorectal cancer screening participation, adjusting for Hispanic/Latino subgroup, marital status, survey language, age, and health insurance status. Next, to explore differences by Hispanic/Latino subgroups (Mexican/Mexican American/Chicano; Puerto Rican; Cuban; Other Hispanic/Latino), results were stratified by subgroup and adjusted for confounding.

Results: There were 611 male participants, with roughly 31% identifying as Puerto Rican, 30% a different Hispanic ethnic background (“Other Hispanic/Latino”), 26% Mexican, and 14% Cuban. More than half (63%) of whom had ever been screened for colorectal cancer. No variations in screening rates were observed across Hispanic/Latino subgroups. Stool-based tests were more commonly used for screening compared to exam-based tests (60% vs. 49%). After adjusting for confounding, masculinity barriers reduced the odds of the screening participation. Differences were observed by Hispanic/Latino subgroup for a few MBMC scale items. Specifically, Cuban men were most likely to report trust in healthcare professionals, but least likely to report receiving quality medical care. Latino men of other Hispanic ethnicity were more likely to report taking risks with their own health if it benefits their family. Among Puerto Rican men, higher scores on the restrictive emotionality subscale were associated with a lower likelihood of screening participation. Conversely, higher scores on the health-related self-reliance subscale were associated with a greater likelihood of screening participation among men of other Hispanic/Latino ethnicity.

Conclusion: Differences in colorectal cancer screening participation by Hispanic/Latino ethnicity were not observed, suggesting barriers to screening may be similar among subgroups. Masculinity barriers to colorectal cancer screening may exist among Latino men, particularly among Puerto Rican men. Intervening on these masculinity-related barriers masculinity may improve colorectal cancer screening uptake among Latino men.
