Vaccines have the potential to reduce morbidity from HPV infections if age-eligible patients receive and parents know about them. Content analyses have demonstrated significant range in the quality of HPV information obtained from different sources. The purpose of this study was to determine the pattern of associations between information source and level of knowledge about HPV and vaccine receipt/intention.
We analyzed the 2007 California Health Interview Survey, a population-based, statewide random digit dial survey, using data on adult females ages 18-65 who had heard about HPV (n=16,806). One-way ANOVA and multivariate logistic regression assessed the associations between source of information (advertisement only, advertisement plus other sources, and non-advertisement sources) and knowledge of HPV (3 or greater correct on a 4-point scale). Multivariate logistic regressions were conducted on a subsample of vaccine-eligible women and parents to assess vaccine uptake or intention.
Less than half of respondents (43%) correctly answered 3 or more of the HPV knowledge questions. Mean knowledge scores were significantly different when comparing women who reported advertisement only, non-advertisement, and advertisement plus other sources of information (p<0.001). In multivariate analysis, women who reported non-advertisement sources (OR 2.44, 95% CI 2.07-2.87) and advertisements plus other sources (OR 3.03, 95% CI 2.57-3.58) were more likely to have knowledge scores above the 75% level than women who relied on advertisements alone. In the subsample of vaccine-eligible women and parents, those who reported advertisements plus other sources (OR 1.85, 95% CI 1.30-2.62) were more likely to have received or intend to receive the vaccine than those who reported advertisements as their sole information source.
Advertisements are the most commonly reported source of information about HPV, and while they inform women of the existence of the vaccine, they do not contribute to accurate knowledge about the virus, nor do they appear to influence vaccine uptake. Other sources may play a larger role in refining knowledge and/or improving uptake.

The vaccinations against human papilloma virus (HPV) are highly effective in preventing persistent infection. The level of knowledge about HPV and the consequences of an infection with this virus are low in the general population and in patients who suffer from HPV-associated diseases. We aimed to compare the level of knowledge about HPV and about the women’s individual malignant disease between women with and without HPV-associated gynecologic cancer as well as the knowledge about individual malignant diseases.
In a pilot study, 51 women with HPV-related cancer (cervical cancer: n = 30; vulvar or vaginal cancer: n = 21) and 60 women with non-HPV associated gynecologic malignancies (ovarian cancer: n = 30; endometrial cancer, n = 30) were included. They answered a questionnaire including questions about personal medical history, risk factors for cancer development, and HPV.
The general level of knowledge of the term “HPV” was low (29.7%, 33/111) and it was similar in patients with HPV-related and non-HPV-associated cancer (18/60, 30.0% vs. 15/51, 29.4%, respectively; p = 1.000). When asked about their disease, 80% (24/30) of women with ovarian cancer correctly named their diagnosis, followed by women with cervical cancer (73.3%, 22/30), endometrial cancer (70%, 21/30) and vaginal or vulvar cancer (42.9%, 9/21; p = 0.008).
The level of knowledge about HPV and the malignant diseases the patient suffered from was low. This applied even to patients with HPV associated malignancies.

ABSTRACT: Approximately 73 million adults in the United States report using the Internet as a source for health information. This study examines the quality, content, and scope of human papillomavirus (HPV) vaccine Internet news coverage starting on the day of its licensure. Information about the HPV vaccine in the media may influence personal attitudes and vaccine uptake.
Using four search engines and six search terms, a sample of 250 Internet articles on the HPV vaccine were identified between June 8, 2006, and September 26, 2006. The coding instrument captured how the headline was depicted and how the vaccine was labeled in addition to information about HPV, cervical cancer, the HPV vaccine, and current social issues and concerns about the vaccine.
Analysis revealed balanced Internet news coverage; 52.4% of Internet news stories were coded as neutral toward the vaccine. Eighty-eight percent of articles labeled the vaccine as a cervical cancer vaccine; 73.5% explained the link between HPV and cervical cancer, although without providing background information on HPV or cervical cancer. Vaccine affordability was the most cited social concern (49.2%). Information about vaccine safety and side effects, duration of vaccine protection, and availability of the catchup vaccine for females aged 13-26 was repeatedly missing.
The HPV vaccine is being marketed as a vaccine to prevent cervical cancer. Comprehensive information on the vaccine, HPV, and cervical cancer continues to be missing from media coverage. Public health educators should monitor online media in an effort to respond to inaccurate information. Barriers to vaccine cost and funding mechanisms need to be addressed more effectively by states. Knowledge of particular media messages could provide a starting point for tackling opposition and uptake issues for future sexually transmitted infection (STI) vaccines.

ABSTRACT: We examined factors associated with information seeking about the human papillomavirus vaccine among mothers of adolescent girls by testing whether information seeking and vaccination intentions for their daughters are associated with perceived vulnerability, severity, and vaccine benefits in an ethnically diverse sample. Mothers (N = 256) of unvaccinated girls living in Dallas, Texas, were surveyed (49% Black, 29% Hispanic, and 18% White). Perceived vulnerability to human papillomavirus was associated with talking with others (odds ratio = 1.71, 95% confidence interval = 1.09, 2.66) and talking with a doctor about the vaccine (odds ratio = 1.42, 95% confidence interval = 1.01, 1.99), and perceived vaccine benefits were associated with vaccination intentions (odds ratio = 2.96, 95% confidence interval = 1.98, 4.42), but the perceived severity was not associated with any dependent measure. Beliefs about human papillomavirus risk are associated with seeking information from a doctor and interpersonal sources, but ethnic minorities are less likely to talk with others about the vaccine.
