RESUMEN
OBJECTIVES: Few studies examine the influence that different sources of medical information has on human papillomavirus (HPV)-related knowledge. We examined the relationship between the primary source of medical information and knowledge about HPV in young adults aged 18-26 years. STUDY DESIGN: This study used cross-sectional data from the Health Information National Trends Survey. METHODS: Respondents (n = 404) self-reported their knowledge about HPV-related diseases and vaccinations and their sources of medical information. Sources of medical information included electronic/print media, family/friends, or a healthcare provider. Bivariate and multivariate analyses were used to examine the association between the source of information and HPV knowledge. RESULTS: Fifty-six percent of respondents used electronic or print media as their primary source of medical information. A greater proportion of Hispanic (40.0%) and black (36.0%) respondents received medical information from their family/friends than white respondents (20.0%). Respondents who received medical information from family/friends had 4.34 (95% confidence interval [CI]: 2.14, 8.79), 4.06 (95% CI: 2.05, 8.04), and 2.35 (95% CI: 1.10, 5.04) times higher odds than those who received information from healthcare providers of not knowing that HPV causes cervical cancer, knowing HPV is a sexually transmitted infection, and hearing about the HPV vaccine, respectively. CONCLUSION: Source of medical information was significantly associated with knowledge of HPV. Receiving medical information from family/friends negatively influenced young adults' HPV knowledge. These findings may guide future interventions to target peer and familial influence on medical decisions.
