Evaluating the Applied Knowledge of BRCA Testing among Spanish-Preferring Latino Americans: The Influence of Acculturation and Literacy.

INTRODUCTION

This study examined applied knowledge about BRCA testing among Spanish-preferring Latino adults in the USA and identifies factors influencing this knowledge, addressing gaps in understanding genetic literacy within this demographic.

METHODS

A national survey was conducted with 196 Spanish-preferring Latino adults. Participants completed a questionnaire measuring applied knowledge of BRCA testing, acculturation variables, and literacy measures. Linear regression analysis explored relationships between these factors and applied knowledge scores.

RESULTS

The mean applied knowledge score was 2.33 out of 6, with 26.7% of participants scoring zero. Regression analysis revealed that younger age, female, higher education, higher e-health literacy, and higher numeracy were associated with greater applied knowledge. US identity and critical media literacy were negatively associated with applied knowledge scores.

CONCLUSION

Spanish-preferring Latino adults demonstrated lower applied knowledge of BRCA testing compared to the general US population, highlighting a significant knowledge disparity. The study identified key factors influencing applied knowledge, such as age, ethnic identity, and e-health literacy, providing insights for developing targeted interventions to improve genetic literacy in this population. These findings can inform culturally competent genetic education initiatives to enhance health outcomes and decision-making regarding genetic testing among Spanish-preferring Latinos.
