Evaluating associations between sources of information, knowledge of the human papillomavirus, and human papillomavirus vaccine uptake for adult women in California
ABSTRACT 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.

ABSTRACT: Romania has the highest cervical cancer burden in Europe. Despite the implementation of two human papillomavirus (HPV) vaccination programmes, the uptake remained extremely low and the programmes were discontinued. Given that media are a common source of information for the public and may influence vaccination decisions, this article sought to explore the content and quality of HPV vaccine media coverage in Romania. We conducted a content analysis of 271 media reports (from newspapers, magazines, videos and informational websites) published online between November 2007 and January 2012. Overall, results indicated that 31.4% of the materials were neutral, 28% were negative or extremely negative, 17% were mixed, while 23.6% were positive towards the vaccine. The most dominant vaccine-related concerns were side effects and insufficient testing. Elementary information about the vaccine and HPV was constantly left out and sometimes inaccuracies were found. Negatively disposed reports were more likely to contain incorrect data about vaccine efficacy and less likely to provide comprehensive information about the vaccine and HPV-related diseases. Some dimensions of media coverage varied across time and media outlets. The present findings suggest that educational interventions are greatly needed as a response to suboptimal and incomplete media coverage of HPV vaccination.

ABSTRACT: Seasonal influenza vaccine was once part of the routine immunization schedule that is routinely offered to all children in Japan, but it is now excluded from the schedule. This study aimed to investigate factors influential to parents' decision to have their children receive seasonal influenza vaccine, as well as types of seasonal influenza vaccine information that is given to parents. We conducted a cross-sectional online survey of 555 participants who have at least one child younger than 13 years of age. Respondents were asked to categorize the history of influenza vaccination of their youngest child as either 'annual' , 'sometimes' , or 'never'. Participants were also asked about potentially influential factors in their decision to have their children receive a seasonal influenza vaccine. A total of 75% of respondents answered that their youngest child had received a seasonal influenza vaccine, and 57% of respondents answered that their child receives the vaccine every year. The higher income group was more likely than the lowest income group to have a history of influenza vaccine uptake. A recommendation from a pediatrician or school/nursery to have their child vaccinated was also positively associated with a history of influenza vaccine uptake. The most common reason for a pediatrician's recommendation was 'it leads to milder symptoms if infected'. The main finding of the study is a significant association between household income and influenza vaccination of the youngest child in the household. We also found that cost could be a barrier to vaccinating children in low income households and that information from pediatricians and schools/nurseries could motivate parents to have their children vaccinated.BMC Infectious Diseases 12/2015; 15(1).

ABSTRACT: To assess the level of HPV knowledge among low income, minority mothers with a child between the ages of 9-17 y. Women who sought care at a university-based clinic and had at least 1 child aged 9 to 17 years were approached. A total of 638 mothers were recruited. Only those who had heard of HPV were included in the correlation analyses (n = 468). HPV knowledge was assessed utilizing a self-administered questionnaire consisting of 20 questions. There were differences between those who had heard of HPV and those who had not. More of those who had not heard of HPV were Hispanic (63%), low-income (89%), and did not graduate high school (59%). Of those who had heard of HPV, the majority did not answer 50% of questions correctly. Few knew the vaccine could prevent genital warts (19.7%). Factors independently associated with HPV knowledge included age, personal history of HPV, cervical dysplasia or cervical cancer, acquiring knowledge from ≥2 sources, having known someone with HPV or cervical cancer, having seen a brochure on the vaccine, and having seen an advertisement for the vaccine. Knowledge regarding HPV is low among low-income women with children in the target age range for HPV vaccination. Increased awareness should focus on genital warts and other cancers, since this population has virtually no knowledge of other health outcomes related to HPV infection. Educational programs tailored to this population need to be developed to increase vaccination. Copyright © 2014 North American Society for Pediatric and Adolescent Gynecology.
