(HealthDay News) – Maternal utilization of preventive care and a history of genital warts may influence utilization of the quadrivalent human papillomavirus vaccine (HPV4) among adolescent boys, according to a study published online July 18 in the American Journal of Public Health.
Rulin C. Hechter, MD, PhD, from Kaiser Permanente Southern California in Pasadena, and colleagues analyzed data that linked maternal information with electronic health records of 254,489 boys (aged 9–17 years) enrolled in a Kaiser Permanente health plan from Oct. 21, 2009, through Dec. 21, 2010.
The researchers found a modest but statistically significant association between initiation of HPV4 series and maternal receipt of influenza vaccine (rate ratio [RR], 1.16) and Pap screening (RR, 1.13). A maternal history of genital warts was linked to higher initiation of HPV4 in boys (RR, 1.47; P=0.1).
“The important role of maternal health characteristics and health behaviors needs be considered in intervention efforts to increase vaccine uptake among boys,” the authors write.
