Vaccines and other factors associated with 1-year HPV vaccination among
girls attending Spanish Primary Care settings
Abstract
Objective To identify primary care recorded factors associated
with the short-term human papillomavirus (HPV) vaccination among girls
and female adolescents. Methods We used the Spanish
Pharmacoepidemiological Research Database for Public Health System to
identify girls aged 9-18 years in 2007-2016 with ≥1 year of primary care
data (start date) and collect baseline characteristics and
consultations. The link between those factors and the 1-year HPV
vaccination was assessed through multivariate adjusted Odds Ratios (OR;
95% CI). Results Among 388,669 girls identified, 14,999 were
vaccinated against HPV during the first year. The vaccination decreased
among girls consulting for social (0.62; 0.55-0.70) or adaptation (0.60;
0.38-0.93) problems, prescriptions of benzodiazepines (0.58; 0.35-0.94)
or drugs for gastrointestinal symptoms (0.58; 0.38-0.89), with recorded
tuberculosis test (0.68; 0.52-0.87), B and C meningitis (0.46;
0.43-0.50) vaccination, consulting the doctor in the last 3 months
(0.92; 0.87-0.98) and with severe thinness (0.68; 0.59-0.78) or obesity
(0.88; 0.78-0.99). The odds increased among girls with abdominal pain
(1.10; 1.04-1.16), prescriptions in the last 3 months (1.17; 1.10-1.25),
and vaccinations against chickenpox (1.16; 1.07-1.27), influenza (1.23;
1.08-1.40), hepatitis (1.46; 1.35-1.58) and diphtheria-tetanus (1.91;
1.82-2.01). Conclusions The correlation between the HPV and
other vaccinations suggested medical (contra)indications or willingness
and knowledge/beliefs that might affect different vaccinations
similarly. The higher frequency of the HPV vaccination among females
requiring specific treatments or with abdominal pain suggested
vulnerability to HPV complications. While a decreased HPV vaccination
linked to certain social and personal situations (and benzodiazepines
treatment) requires further research.
