Parents and other caretakers of young women learned about human papillomavirus (HPV) vaccine primarily from advertisements sponsored by the pharmaceutical company that makes the vaccine, a new study from the University of North Carolina at Chapel Hill shows.
In the study, published in the February issue of the journal Cancer Epidemiology Biomarkers & Prevention , researchers from the UNC Gillings School of Global Public Health and the UNC Lineberger Comprehensive Cancer Center interviewed a sample of parents of girls aged 10 to 18 years old in areas of North Carolina with high rates of cervical cancer. Parents were asked whether they knew a vaccine against HPV is now available and how they heard of it.
HPV infection, which causes genital warts, cervical cancer and other cancers, can be prevented by the new vaccine.
"While regular screening prevents cervical cancer, gaps in our health-care system cause thousands of women to die from cervical cancer every year," said Noel Brewer, Ph.D., UNC assistant professor of health behavior and health education and senior author of the paper. "Our goal was to assess how parents are getting information about HPV vaccine to make sure they are getting the message about cervical cancer prevention."
The researchers found that 82 percent of parents had heard of HPV vaccine, which is twice as many as previous studies had shown. News coverage of HPV was high around the FDA's approval of the first vaccine in 2006, which accounted for some awareness.
However, the survey also found that the primary way parents heard of the vaccine was through pharmaceutical company ads. In all, 83 percent of parents had heard of it this way.
"Drug companies are the de facto health educators for the nation on HPV vaccine," said Brewer. "We need to make sure the public is getting balanced information about the vaccine so they can make informed decisions for their daughters."
