Abstract
BACKGROUND: This cross-sectional study explored how masculinity beliefs may influence colorectal cancer (CRC) screening participation among ethnic subgroups of screening-age-eligible (45-75 years) Hispanic/Latino men. METHODS: Using a consumer panel, we recruited self-identified Hispanic/Latino men fluent in English or Spanish, and residing in Florida, New York, or Texas. The Masculinity Barriers to Medical Care (MBMC) scale and its six subscales were used to assess masculinity beliefs. Multivariable logistic regression was used to estimate the association between MBMC and CRC screening participation, adjusting for Hispanic/Latino subgroup, marital status, survey language, age group, and health insurance status. Results were then stratified by Hispanic/Latino subgroup. RESULTS: Of the participants (n=611), approximately 31% identified as Puerto Rican, 30% as other Hispanic/Latino, 26% as Mexican, and 14% as Cuban; 63% had ever been screened for CRC. We found no differences in the prevalence of screening participation by Hispanic/Latino subgroup. The majority of participants had completed both a stool-based test and an exam-based screening test (29.3%). After adjusting for confounding, MBMC reduced the odds of screening participation. Slight MBMC-subscale differences were observed by Hispanic/Latino subgroup. For example, higher scores on the Restrictive Emotionality subscale were associated with a lower likelihood of screening participation among Puerto Rican men, but higher odds of screening for Cuban men. CONCLUSIONS: Masculinity barriers to CRC screening may exist. Tailored interventions to address masculinity barriers among specific Latino subgroups may improve CRC screening uptake in this population.
