Human papillomavirus (HPV) causes a number of cancers that disproportionally affect Latinos yet there is a paucity of research on interventions to increase HPV vaccination among this population. We sought to evaluate the efficacy of a web-based, individually customizable intervention, called CHICOs (Combatting HPV Infection and Cancers, tailored intervention) for its impact on HPV vaccine utilization. We conducted a three-armed, randomized, controlled trial in the waiting rooms of five family medicine practices from June 2014-February 2016 where CHICOS was compared to an iPad-based version of the Vaccine Information Sheet from the Centers for Disease Control and Prevention (untailored intervention), and usual care. Pair-wise comparisons between study arms of 6 different measures of HPV vaccine uptake were assessed, with analyses stratified by adolescents versus young adults. Of the 1,294 participants enrolled in the study, 1,013 individuals could be assessed for vaccination. Across study arms, 265 adolescents, but only 18 young adults, received an HPV vaccine dose during the study period. In both intention-to-treat and per-protocol analyses there were essentially no differences between the CHICOS and untailored arms in any vaccination measure, or between the untailored or CHICOS arms and usual care. Our study suggests that a tailored educational intervention may not be effective for increasing HPV vaccine uptake among Latino adolescents or young adults. However, the higher than expected baseline levels of positive vaccination attitudes of study participants could have diminished the statistical power of the study.Trial Registration Number: ClinicalTrials.gov (NCT02145156).
Infants infected with Bordatella pertussis experience high morbidity and significant mortality. Vaccinating pregnant mothers with the tetanus-diphtheria-acellular pertussis (Tdap) vaccine is a recommended strategy for preventing infant pertussis. This is especially important for mothers living in poverty and from racial and ethnic minority populations as these groups are at increased risk of having a pertussis-affected infant. Using the Health Belief Model as a framework, we surveyed a convenience sample of pregnant mothers representing these high-risk populations to understand factors associated with Tdap vaccine uptake during their pregnancy. Among the 316 mothers surveyed, 82% had gotten or planned to get Tdap that same day even though 63% of the sample had concerns about the safety of the vaccine during pregnancy. Perceived benefits and norms were the Health Belief Model constructs most consistently associated with Tdap vaccination. Although 32% of women reported prior Tdap vaccine receipt, this factor was not associated with Tdap vaccination during the current pregnancy, contrasting studies of vaccination done in non-pregnant populations. Important variations in attitudes were apparent, with Spanish-speaking women significantly more likely to have concerns about the vaccine's safety and efficacy than English-speaking women. This study indicates that among this high-risk population acceptance of Tdap vaccine during pregnancy is high. However, our results suggest that it may be important to modify information conveyed about the safety and importance of Tdap during pregnancy based on individual level factors such as language or acculturation.
Background: Infants in utero during the terrorist attacks of September 11, 2001 may have been negatively affected by maternal stress. Studies to date have produced contradictory results.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
