Breast cancer screening outcomes among Mexican-origin Hispanic women participating in a breast cancer screening program

Understanding the role of access in Hispanic cancer screening disparities

BACKGROUND

Hispanic populations in the United States experience numerous barriers to care access. It is unclear how cancer screening disparities between Hispanic and non-Hispanic White individuals are explained by access to care, including having a usual source of care and health insurance coverage.

METHODS

A secondary analysis of the 2019 National Health Interview Survey was conducted and included respondents who were sex- and age-eligible for cervical (n = 8316), breast (n = 6025), or colorectal cancer screening (n = 11,313). The proportion of ever screened and up to date for each screening type was compared.  Regression models evaluated whether controlling for reporting a usual source of care and type of health insurance (public, private, none) attenuated disparities between Hispanics and non-Hispanic White individuals.

RESULTS

Hispanic individuals were less likely than non-Hispanic White individuals to be up to date with cervical cancer screening (71.6% vs. 74.6%) and colorectal cancer screening (52.9% vs. 70.3%), but up-to-date screening was similar for breast cancer (78.8% vs. 76.3%). Hispanic individuals (vs. non-Hispanic White) were less likely to have a usual source of care (77.9% vs. 86.0%) and more likely to be uninsured (23.6% vs. 7.1%). In regressions, insurance fully attenuated cervical cancer disparities. Controlling for both usual source of care and insurance type explained approximately half of the colorectal cancer screening disparities (adjusted risk difference: -8.3 [-11.2 to -4.8]).

CONCLUSION

Addressing the high rate of uninsurance among Hispanic individuals could mitigate cancer screening disparities. Future research should build on the relative successes of breast cancer screening and investigate additional barriers for colorectal cancer screening.

PLAIN LANGUAGE SUMMARY

This study uses data from a national survey to compare cancer screening use those who identify as Hispanic with those who identify as non-Hispanic White. Those who identify as Hispanic are much less likely to be up to date with colorectal cancer screening than those who identify as non-Hispanic White, slightly less likely to be up to date on cervical cancer screening, and similarly likely to receive breast cancer screening. Improving insurance coverage is important for health equity, as is further exploring what drives higher use of breast cancer screening and lower use of colorectal cancer screening.

Effectiveness of a Breast Cancer Education Screening and NavigaTion (BEST) Intervention among Hispanic Women

BACKGROUND

In the United States, breast cancer remains one of the most diagnosed cancers among females and remains the second leading cause of cancer death. In addition, breast cancer is most likely diagnosed at an advanced stage among Hispanic females in the United States due to lower mammogram utilization.

AIMS

The objective of this study was to determine the effectiveness of a multilevel, multicomponent community-based breast cancer screening intervention called the Breast Cancer Education Screening and NavigaTion (BEST) program. The primary outcome was the completion of a screening mammogram 4 months post-intervention.

METHOD

We used a pragmatic approach for evaluation, utilizing a quasi-experimental delayed intervention design. We recruited women from the community aged between 50 and 75, uninsured or underinsured, and overdue for screening.

RESULTS

Six hundred participants were recruited (300 intervention and 300 control). Among completers, the screening rate was 97% in the intervention group and 4.4% in the control group (RR = 22.2, 95% CI: 12.5-39.7, p < .001). In multivariable analysis, age ≥ 65 (RR = 1.29, p = .047), perceived benefits (RR = 1.04, p = .026), curability (RR = 1.24, p < .001), subjective norms (RR = 1.14, p = .014), and fatalism (RR = .96, p = .004) remained significantly associated with screening outcome.

CONCLUSION

A multicomponent, bilingual, and culturally tailored intervention effectively facilitated breast cancer screening completion in an underserved population of Hispanic women. Individuals with improved screening outcomes were more likely to have higher positive beliefs. Our study has important implications regarding using multicomponent interventions in increasing breast cancer screening completion in poorly screened populations. It also highlights differences in health belief motivation for breast cancer screening completion.
