Heterogeneity in Trust of Cancer Information among Hispanic Adults in the United States: An Analysis of the Health Information National Trends Survey

Background: Hispanics are differentially burdened by inequities in cancer outcomes. Increasing knowledge about cancer and cancer services among Hispanics may aid in reducing inequities, but little is known about what information sources are considered most effective or most trusted by this diverse population. The goal of this study was to examine heterogeneity in trust of cancer information from various media sources among U.S. Hispanic adults. Methods: Using data from the Health Information National Trends Survey (HINTS) 4, Cycles 2 and 4 and HINTS 5, Cycle 2, we examined nine trust questions, divided into four domains of health communication sources [doctor, government health/charitable organizations, media (including Internet), and family/friends and religious organizations]. Independent variables examined were gender, Hispanic ethnic categories (Mexican American, Cuban/Puerto Rican, and other Hispanics), age, education, income, language, and nativity. We used multivariable logistic regression with survey weights to identify independent predictors of cancer information source use and trust. Results: Of the 1,512 respondents, trust in sources ranged from 27% for radio to 91% for doctors. In multivariable models, Cubans/Puerto Ricans were twice as likely to trust cancer information from print media compared with Mexican Americans. Hispanics 75 years and older were nearly three times as likely to trust cancer information from religious organizations compared with those ages 18 to 34. Hispanic women were 59% more likely to trust cancer information from the Internet compared with men. Conclusions: Subgroup variability in source use and trust may be masked by broad racial and ethnic categories. Impact: Among Hispanics, there is significant variation by ethnicity and other sociodemographics in trust of sources of cancer information across multiple constructs, with notable implications for disseminating cancer information.
