by N.R. Saltmarsh, staff medical writer - To get the participation of teenage girls in a trial of human papillomavirus (HPV) vaccine, researchers should not discount the support of their parents, according to a study published in the Archives of Medical Research.
To that end, they should educate parents about the main cause of cervical cancer and the potential value of a vaccine, said E. Lazcano-Ponce and colleagues at the National Institute of Public Health, Morales, Mexico.
"A scenario that must be considered when testing prophylactic HPV vaccines in teenagers is the parents' acceptability of their daughters' participation in the study," said Lazcano-Ponce and team.
They surveyed 880 women between the ages of 15 and 49 years in the metropolitan area of Cuernavaca, about their knowledge of risk factors for cervical cancer and their perception of the usefulness of vaccines. In an education component of the study, researchers provided survey respondents with information on the main risk factors for cervical cancer and the future availability of a HPV vaccine to prevent it.
Parents were surveyed again, this time about their potential acceptance of an HPV vaccine for their teenage daughters. Lazcano-Ponce and coworkers considered the degree of acceptability in light of sociodemographic and reproductive factors.
Only 1.9% of respondents knew that the principal risk factor was infection with HPV, but 84.2% were aware of the usefulness of vaccines; 83.6% of the women said they would allow their daughters to participate in a trial to evaluate the effectiveness of an HPV vaccine.
