ObjectivesTo determine whether the probability of having heard about human papillomavirus (HPV) vaccination differs by socio-demographic characteristics among Colombian women; and whether the effect of predictors of having heard about HPV vaccination varies by educational levels and rural/urban area of residence.MethodsData of 53,521 women aged 13–49 years were drawn from the 2010 Colombian National Demographic and Health Survey. Women were asked about aspects of their health and their socio-demographic characteristics. A logistic regression model was used to identify factors associated with having heard about HPV vaccination. Educational level and rural/urban area of residence of the women were tested as modifier effects of predictors.Results26.8% of the women had heard about HPV vaccination. The odds of having heard about HPV vaccination were lower among women: in low wealth quintiles, without health insurance, with subsidized health insurance, and those who had children (p < 0.001). Although women in older age groups and with better education had higher probabilities of having heard about HPV vaccination, differences in these probabilities by age group were more evident among educated women compared to non-educated ones. Probability gaps between non-educated and highly educated women were wider in the Eastern region. Living in rural areas decreased the probability of having heard about HPV vaccination, although narrower rural/urban gaps were observed in the Atlantic and Amazon-Orinoquía regions.ConclusionsAlmost three quarters of the Colombian women had not heard about HPV vaccination, with variations by socio-demographic characteristics. Women in disadvantaged groups were less likely to have heard about HPV vaccination.  相似文献

BackgroundSchool-based HPV vaccination in the UK will soon be extended to boys. Based on other countries’ experience, uptake may initially be lower in boys than girls. We assessed HPV vaccine attitudes and decision-making in parents of boys and girls, to explore sex differences and inform public health messages.MethodsWe carried out a cross-sectional population-based survey using home-based interviews in spring 2019. Participants were adults in England and Wales, with a child in school years 5–7 (aged 9–12 and eligible for HPV vaccination within 3 years). Measures included awareness of HPV and the vaccine, demographic factors, previous vaccine refusal and (after exposure to brief information) whether participants would allow their child to have the HPV vaccine (decided to vaccinate; decided not to vaccinate; undecided). We also assessed vaccine attitudes. Data were weighted to adjust for non-response. Multinomial logistic regression was used to explore predictors of deciding to (or not to) vaccinate compared with being undecided.ResultsAmong 1049 parents (weighted n = 1156), 55% were aware of HPV and the girls’ vaccination programme, but only 23% had heard of plans to vaccinate boys. After information exposure, 62% said they would vaccinate their child, 10% would not, and 28% were undecided. Parents of girls were more willing to vaccinate than parents of boys (adjusted odds ratio: 1.80 (1.32–2.45)). Positive attitudes and HPV/vaccine awareness were significantly independently associated with deciding to vaccinate. Previous vaccine refusal for a child was the strongest predictor of not wanting the HPV vaccine.ConclusionsOur findings suggest a need for public health campaigns to raise awareness of plans to extend HPV vaccination to boys. Reassuringly only 10% of all parents were unwilling to vaccinate and our data suggest further information, including about safety and efficacy, may be important in supporting undecided parents to make the decision to vaccinate.  相似文献

ObjectivesTo determine whether five psychosocial variables, namely, religiosity, morality, perceived promiscuity, cancer worry frequency, and cancer worry severity, predict young women's intentions to receive the human papillomavirus (HPV) vaccination.MethodsFemale undergraduate students (n = 408) completed an online survey. Questions pertaining to hypothesized predictors were analyzed through bivariate correlations and hierarchical regression equations. Regressions examined whether the five psychosocial variables of interest predicted intentions to vaccinate above and beyond controls. Proposed interactions among predictor variables were also tested.ResultsStudy findings supported cancer worry as a direct predictor of HPV vaccination intention, and religiosity and sexual experience as moderators of the relationship between concerns of promiscuity reputation and intentions to vaccinate. One dimension of cancer worry (severity) emerged as a particularly robust predictor for this population.ConclusionsThis study provides support for several important, yet understudied, factors contributing to HPV vaccination intentions among college-aged women: cancer worry severity and religiosity. Future research should continue to assess the predictive contributions of these variables and evaluate how messages and campaigns to increase HPV vaccination uptake can utilize religious involvement and worry about cancer to promote more effectively HPV vaccination as a cancer prevention strategy.  相似文献

BackgroundSexual minority women (lesbian, bisexual, and other women who have sex with women) are at risk for human papillomavirus (HPV) infection and HPV-related disease, demonstrating the importance of HPV vaccination for these women.MethodsWe conducted an online survey of sexual minority women ages 18–45 from the United States (n = 505) in October 2019, about two months after HPV vaccine recommendations were expanded to include ages 27–45. Multivariable Poisson regression identified correlates of HPV vaccine initiation (i.e., receipt of at least one HPV vaccine dose).ResultsOverall, 65% of participants ages 18–26 and 33% of participants ages 27–45 had initiated the HPV vaccine series. Among participants ages 18–26, initiation was more common among those who had received a healthcare provider recommendation (RR = 2.19, 95% CI: 1.64–2.93) or had disclosed their sexual orientation to their primary healthcare provider (RR = 1.33, 95% CI: 1.07–1.65). Among initiators ages 27–45, a large majority (89%) reported receiving their first dose before turning age 27. Initiation was more common among participants ages 27–45 who had received a healthcare provider recommendation (RR = 3.23, 95% CI: 2.31–4.53) or who reported greater perceived social support for HPV vaccination (RR = 1.22, 95% CI: 1.05–1.40). Several reasons for not yet getting HPV vaccine differed by age group (ages 18–26 vs. ages 27–45; all p < 0.05).ConclusionsMany sexual minority women, particularly those ages 27–45, remain unvaccinated against HPV. Findings provide early insight into HPV vaccine coverage among adult women and highlight key leverage points for increasing vaccination among this population.  相似文献

BackgroundBetween 2010 and 2014, the percentage of 13–17 year-old girls administered ≥3 doses of the human papilloma virus (HPV) vaccine (“fully vaccinated”) increased by 7.7 percentage points to 39.7%, and the percentage not administered any doses of the HPV vaccine (“not immunized”) decreased by 11.3 percentage points to 40.0%.ObjectiveTo evaluate the complex interactions between parents’ vaccine-related beliefs, demographic factors, and HPV immunization status.MethodsVaccine-related parental beliefs and sociodemographic data collected by the 2010 National Immunization Survey-Teen among teen girls (n = 8490) were analyzed. HPV vaccination status was determined from teens’ health care provider (HCP) records.ResultsAmong teen girls either unvaccinated or fully vaccinated against HPV, teen girls whose parent was positively influenced to vaccinate their teen daughter against HPV were 48.2 percentage points more likely to be fully vaccinated. Parents who reported being positively influenced to vaccinate against HPV were 28.9 percentage points more likely to report that their daughter's HCP talked about the HPV vaccine, 27.2 percentage points more likely to report that their daughter's HCP gave enough time to discuss the HPV shot, and 43.4 percentage points more likely to report that their daughter's HCP recommended the HPV vaccine (p < 0.05). Among teen girls administered 1–2 doses of the HPV vaccine, 87.0% had missed opportunities for HPV vaccine administration.ConclusionResults suggest that an important pathway to achieving higher ≥3 dose HPV vaccine coverage is by increasing HPV vaccination series initiation though HCP talking to parents about the HPV vaccine, giving parents time to discuss the vaccine, and by making a strong recommendation for the HPV. Also, HPV vaccination series completion rates may be increased by eliminating missed opportunities to vaccinate against HPV and scheduling additional follow-up visits to administer missing HPV vaccine doses.  相似文献

ObjectiveRacial and ethnic disparities persist in cervical cancer cases, 90% of which are caused by the human papillomavirus (HPV). Suboptimal vaccine uptake is problematic, particularly among Latinx women, who have the highest cervical cancer incidence compared with other racial/ethnic groups. We examined the association of self-efficacy and HPV vaccination intention among Latinx immigrant mothers of unvaccinated 9- to 12-year-old girls.MethodsAn interviewer-administered survey assessed baseline sociodemographic information, knowledge and perceived risk of cervical cancer and HPV, self-efficacy, and intention to vaccinate among 313 Latinx immigrant mothers in Alabama from 2013 to 2017 before the implementation of an intervention to promote HPV vaccination.ResultsParticipants were, on average, 35 years old, with 9 years of education, and had lived in the United States for 12 years. Mothers who perceived their daughters were at risk of HPV infection were more likely to be vaccine intent than their hesitant counterparts (p < .001). Vaccine hesitancy was more common in those with lower education, low HPV and cervical cancer knowledge, and lower perceived self-efficacy scores (p < .001). Self-efficacy was associated with vaccine intention when controlling for other variables (p < .001). The only variable associated with self-efficacy was HPV awareness (p = .001).ConclusionsPrograms promoting HPV vaccination among Latinx immigrants should include educational components regarding risks of HPV infection and cervical cancers in addition to information regarding access to vaccination services. Knowledge of risks and access may heighten perceptions of self-efficacy and improve vaccine uptake among this population.  相似文献

BackgroundCervical cancer is the second most common cancer in Chinese women. Human papillomavirus (HPV) vaccines have not yet been introduced in the Chinese national immunization program, and people vaccinate voluntarily at their own expense. Therefore, it is important to study the factors that could impact parents' decisions for HPV vaccination.ObjectiveTo quantify parental preferences regarding HPV vaccination for junior middle school-aged girls.MethodA discrete choice experiment (DCE) survey was conducted to assess parents' preferences for HPV vaccines. Data were collected from parents of girls aged 12–16 years in 11 middle schools of Shandong Province. We evaluated preferences for five attributes of HPV vaccination (vaccine effectiveness, protection duration, risk of side effects, cost, and vaccination location). Conditional logit regressions were adopted for analyses.Results995 parents completed valid DCE questions. All attributes influenced parents’ willingness to vaccinate. Comparatively highly educated parents preferred more on higher vaccine effectiveness and lower side effects risks while more intended to accept higher prices. Parents were willing to trade 2326.32 CNY for an increase in HPV vaccine effectiveness from 50% to 90%. Nearly 70% percent of the respondents were predicted to prefer multiple improvements in HPV vaccination (protection increased from 70% to 95%, duration increased from 9 years to 15 years, and vaccination location changed from vaccination center to school) to the base case.ConclusionVarious vaccine characteristics and implementation strategies influence respondents’ preferences. Health education with evidence-based information about HPV vaccines would help parents make informed decisions. The findings can also assist agencies responsible for HPV vaccination implementation and cervical cancer prevention in China in decisions regarding vaccination financing and vaccine approval.  相似文献

PurposeWe aimed to identify human papillomavirus (HPV) and HPV vaccine-related knowledge, attitudes, and beliefs among women aged 27–45 years, who became eligible for HPV vaccination in 2018.MethodsEight virtual focus groups were conducted with 52 unvaccinated cisgender women aged 27–45 years living in Southern California's Inland Empire. Themes related to women's knowledge, attitudes, and beliefs were systematically identified using the rigorous and accelerated data reduction technique.ResultsThe sample was diverse: 62% of participants were Hispanic, Black, or Asian; 17% identified as lesbian or bisexual; and annual household incomes ranged from $0 to $260,000 (median, $60,500). Key qualitative themes centered on 1) questions about HPV and HPV vaccination, 2) knowledge and beliefs about HPV and HPV vaccination, 3) concerns about vaccine side effects and safety, 4) low perceived benefits of vaccination, and 5) social factors influencing vaccine acceptance. Few participants were aware adults aged 27–45 years are eligible for HPV vaccination or that vaccination can still be beneficial after sexual debut. Many believed HPV vaccination caused serious side effects among adolescents and questioned whether safety had been adequately studied for newly eligible adults. Although many participants associated HPV vaccination with social stigma, some emphasized that vaccination was a way to exercise control over their health and prevent illness, given they could not always control the actions of their sexual contacts.ConclusionsFindings provide insight into knowledge, attitudes, and beliefs about HPV and HPV vaccination among women aged 27–45 years, which may be useful for informing interventions to promote shared clinical decision-making between patients and health providers.  相似文献

ObjectiveHPV vaccine uptake in U.S. East African adolescents is low. We developed and evaluated a culturally-targeted interactive educational intervention for East African immigrant mothers to increase HPV-vaccine-related knowledge, attitudes, and intentions to vaccinate adolescent children.MethodsEligible mothers had ≥ 1 11–17-year-old child and reported all children’s HPV vaccination status as unvaccinated or unknown. The intervention was delivered via 10 dinners in the Seattle metropolitan area (8 with the Somali community, 2 with the Ethiopian community). Educational presentations and pre/post-tests on knowledge, attitudes, and intentions were conducted in the participants’ native language by a co-ethnic physician. Pre/post differences in responses were evaluated with McNemar’s tests and GEE models. HPV vaccination uptake 6-months post-intervention was evaluated using state immunization registry data.ResultsOf 115 participating mothers, most (84%) were Somali and < 40 years of age (60%). Median years of formal education was 8 (range 0–16), and 61% reported a household income <$25,000. Knowledge of HPV/HPV-vaccines was low pre-intervention, with correct responses ranging from 4% to 39% (61%-91% of responses were “not sure”); correct post-intervention responses ranged from 29% to 97%. Pre-intervention, only 12% of mothers thought they had enough information to make a decision about vaccination, compared to 90% post-intervention. Pre-intervention, only 16% of mothers reported that they were somewhat or very likely to vaccinate their child, compared to 83% post-intervention. All pre/post comparisons were statistically significantly different (p < 0.0001). Although mothers were more likely to report correct HPV-related knowledge and positive vaccine attitudes and intentions post-intervention, only two mothers’ children initiated HPV vaccination within 6 months after the intervention.ConclusionsResults illustrate that a culturally targeted educational intervention effectively increased East African mothers’ HPV vaccine-related knowledge, attitudes, and intentions to vaccinate their adolescent children. Future research should identify additional intervention components that can bridge the gap between intention and behavior to facilitate HPV vaccine uptake.  相似文献

BackgroundIn Australia, high and widespread uptake of the quadrivalent human papillomavirus (HPV) vaccine has led to substantial population-level reductions in the prevalence of quadrivalent vaccine targeted HPV genotypes 6/11/16/18 in women aged ≤ 35 years. We assessed risk factors for HPV detection among 18–35 year old women, 9–12 years after vaccine program introduction.MethodsWomen attending health services between 2015 and 2018 provided a self-collected vaginal specimen for HPV genotyping (Roche Linear Array) and completed a questionnaire. HPV vaccination status was validated against the National Register. Adjusted odds ratios (aORs) and 95% confidence intervals (CI) were calculated for factors associated with HPV detection.ResultsAmong 1564 women (median age 24 years; IQR 21–27 years), Register-confirmed ≥ 1-dose vaccine coverage was highest at 69.3% and 68.1% among women aged 18–21 and 22–24 years respectively, decreasing to 42.9% among those aged 30–35 years. Overall prevalence of quadrivalent vaccine-targeted HPV types was very low (2.0%; 95% CI: 1.4–2.8%) and influenced only by vaccination status (5.5% among unvaccinated compared with 0.7% among vaccinated women; aOR = 0.13 (95% CI: 0.05–0.30)). Prevalence of remaining HPV types, at 40.4% (95% CI: 38.0–42.9%), was influenced by established risk factors for HPV infection; younger age-group (p-trend < 0.001), more recent (p < 0.001) and lifetime sexual partners (p-trend < 0.001), but not vaccination status. Prevalence of HPV31/33/45, which shared risk factors with that of non-vaccine targeted HPV types, was also lower among vaccinated (4%) compared with unvaccinated (7%) women (aOR = 0.51; 95% CI: 0.29–0.89), indicative of cross-protection.ConclusionVaccination has changed the epidemiology of HPV infection in Australian women, having markedly reduced the prevalence of vaccine-targeted types, including amongst women with known risk factors for infection. Vaccinated women appear to be benefiting from modest cross-protection against types 31/33/45 afforded by the quadrivalent HPV vaccine. These results reinforce the importance of HPV vaccination.  相似文献

IntroductionThe objective of this study was to assess incremental costs and benefits of a human papillomavirus (HPV) vaccination program expanded to include “mid-adults” (adults aged 27 through 45 years) in the United States.MethodsWe adapted a previously published, dynamic mathematical model of HPV transmission and HPV-associated disease to estimate the incremental costs and benefits of a 9-valent HPV vaccine (9vHPV) program for people aged 12 through 45 years compared to a 9vHPV program for females aged 12 through 26 years and males aged 12 through 21 years.ResultsA 9vHPV program for females aged 12 through 26 years and males aged 12 through 21 years was estimated to cost < $10,000 quality-adjusted life year (QALY) gained, compared to no vaccination. Expanding the 9vHPV program to include mid-adults was estimated to cost $587,600 per additional QALY gained when including adults through age 30 years, and $653,300 per additional QALY gained when including adults through age 45 years. Results were most sensitive to assumptions about HPV incidence among mid-adults, current and historical vaccination coverage, vaccine price, and the impact of HPV diseases on quality of life.ConclusionsMid-adult vaccination is much less cost-effective than the comparison strategy of routine vaccination for all adolescents at ages 11 to 12 years and catch-up vaccination for women through age 26 years and men through age 21 years.  相似文献

ObjectiveTo describe knowledge about human papillomavirus (HPV) and HPV vaccination among women ages 19 to 26 seeking a variety of services at reproductive health centers. A secondary objective was to identify common sources of HPV information.MethodsTen reproductive health centers enrolled 365 women ages 19 to 26 in a randomized, controlled trial to determine the effect of automated reminder messages on HPV vaccine completion. Using responses from a 61-item self-administered baseline questionnaire completed before initiating the HPV vaccine, this subanalysis assessed participants' knowledge regarding HPV and the HPV vaccine.ResultsKnowledge of HPV prevention, transmission, and disease outcomes among the study population was highly variable. The mean HPV knowledge score was 11.0 of a possible 19 (SD = 3.8). Most participants (77%) had heard of the HPV vaccine before completing the questionnaire and indicated that their primary sources of information about the vaccine were television ads (61%), health care providers (52%), and friends (45%).ConclusionsDespite a relatively high awareness of the vaccine, specific knowledge regarding HPV and the HPV vaccine varied substantially and participant scores highlighted knowledge gaps among vaccine-eligible young women. Media, health care providers, and friends were identified by participants as sources of information and may influence their knowledge of HPV and the HPV vaccine.  相似文献

IntroductionThe HPV vaccine prevents HPV-related cancers and genital warts, which cause significant morbidity and mortality in the US. The vaccine is targeted toward 11–12 year old males and females, but is recommended for “catch-up” vaccination until age 26 for females. Young adult females (18–26 years) represent a unique group that may face distinct barriers to HPV vaccination, one of which is relationship status. The purpose of this study was to assess how relationship status impacts interest in HPV vaccination and primary reasons for non-vaccination among 18–26 year old young adult women.MethodsThe National Health Interview Survey 2010 was examined among unvaccinated females, 18–26 years (N = 1457). A survey-weighted logistic regression analysis with conversion to prevalence ratios assessed how interest in the HPV vaccine (yes/no) was influenced by relationship status (married, living with a partner, other, single) among young adult women. A Rao-Scott chi-square test examined differences between primary reasons for non-vaccination and relationship status among HPV vaccine uninterested women.ResultsAmong unvaccinated women, 31.4% were interested in the HPV vaccine. Women who were living with a partner (PR = 1.45, 95%CI 1.06–1.90) and single (PR = 1.42, 95%CI 1.11–1.76) were significantly more likely than married women to be interested in the HPV vaccine, while controlling for socio-demographic and other known risk factors. Additionally, primary reasons for non-vaccination differed based on relationship status among uninterested women (p < 0.01). Women who were married were more likely to cite not needing the vaccine compared to never married women (p < 0.05).ConclusionRelationship status in young adulthood impacts HPV vaccine interest and decision-making among a national sample of women. Primary reasons for non-interest in the vaccine may be shaped by attitudes and knowledge about the HPV vaccine that differ by relationship status. Future research is needed to elucidate ways to overcome relationship status as a barrier to HPV vaccination.  相似文献

BackgroundPrevention of pre-invasive cervical lesions is an important benefit of HPV vaccines, but demonstrating impact on these lesions is impeded by changes in cervical cancer screening. Monitoring vaccine-types associated with lesions can help distinguish vaccine impact from screening effects. We examined trends in prevalence of HPV 16/18 types detected in cervical intraepithelial neoplasia 2, 3, and adenocarcinoma in situ (CIN2+) among women diagnosed with CIN2+ from 2008 to 2012 by vaccination status. We estimated vaccine effectiveness against HPV 16/18-attributable CIN2+ among women who received ≥1 dose by increasing time intervals between date of first vaccination and the screening test that led to detection of CIN2+ lesion.MethodsData are from a population-based sentinel surveillance system to monitor HPV vaccine impact on type-specific CIN2+ among adult female residents of five catchment areas in California, Connecticut, New York, Oregon, and Tennessee. Vaccination and cervical cancer screening information was retrieved. Archived diagnostic specimens were obtained from reporting laboratories for HPV DNA typing.ResultsFrom 2008 to 2012, prevalence of HPV 16/18 in CIN2+ lesions statistically significantly decreased from 53.6% to 28.4% among women who received at least one dose (Ptrend < .001) but not among unvaccinated women (57.1% vs 52.5%; Ptrend = .08) or women with unknown vaccination status (55.0% vs 50.5%; Ptrend = .71). Estimated vaccine effectiveness for prevention of HPV 16/18-attributable CIN2+ was 21% (95% CI: 1–37), 49% (95% CI: 28–64), and 72% (95% CI: 45–86) in women who initiated vaccination 25–36 months, 37–48 months, and >48 months prior to the screening test that led to CIN2+ diagnosis.ConclusionsPopulation-based data from the United States indicate significant reductions in CIN2+ lesions attributable to types targeted by the vaccines and increasing HPV vaccine effectiveness with increasing interval between first vaccination and earliest detection of cervical disease.  相似文献

PurposeHispanic women experience a disproportionate burden of cervical cancer morbidity and mortality compared to non-Hispanic women. Increasing HPV vaccination among Hispanic adolescents can help alleviate disparities. This study aimed to identify parental psychosocial predictors associated with HPV vaccine initiation and correlates of parental intentions to obtain the vaccine for their Hispanic adolescent daughters aged 11–17 years.MethodsThis study is part of a larger three-arm randomized controlled trial testing the effectiveness of interventions to increase HPV vaccination. Parents of adolescent females were recruited in community clinics where we conducted baseline surveys. We obtained electronic medical records six months after baseline to assess vaccination status. Multilevel logistic regression was used to identify correlates of parental intentions to vaccinate and predictors of HPV vaccine initiation. Analyses with initiation as the outcome also controlled for intervention study arm. The Integrated Behavioral Model guided selection of psychosocial and outcome variables.ResultsOur sample (n = 765) consisted mostly of mothers with less than a high school education born outside of the U.S. Forty-one percent had a household income less than $15,000. Most daughters had public or private insurance. Twenty-one percent initiated the HPV vaccine series. Correlates of intention to vaccinate intention included subjective norms related to daughter’s doctor (AOR = 1.04; 95% CI 1.01–1.07), belief that the vaccine is safe (AOR = 1.38; 95% CI 1.06–1.78), self-efficacy to obtain the vaccine for their daughter (AOR = 2.39; 95% CI 1.52–3.77), and parental concern about vaccine side effects (AOR = 0.73; 95% CI 0.60–0.89). Intentions predicted initiation (AOR = 2.01; 95% CI 1.10–5.26); concern about sexual disinhibition decreased the odds of having a vaccinated daughter at follow-up (AOR = 0.66; 95% CI 0.47–0.92).DiscussionParental intention and concerns about sexual disinhibition predict vaccine initiation. Further research is needed to explore the role of intention as a potential mediator between psychosocial variables and vaccination status.  相似文献

ObjectiveThis study aims to investigate acceptance and willingness to pay for HPV vaccination among adult women in China.MethodsAn online survey was sent to mothers aged 27–45 years of primary school pupils in the Fujian province, China. Participants completed questions about HPV related knowledge and health beliefs, intention to take the HPV vaccine and the willingness to pay for bivalent vaccine (2vHPV), quadrivalent vaccine (4vHPV), and 9-valent HPV vaccine (9vHPV).ResultsOf a total of 2339 complete responses, 58.3% reported intent to obtain HPV vaccine. Mothers who were younger in age, residing in urban, working in managerial or professional occupations, who knew someone with cervical cancer and who were able to make independent decisions about the HPV vaccine (vs. joint decision with spouse) were more likely to express intent to have HPV vaccination. Perceived barriers, cues to action and self-efficacy were three of the constructs in the health belief model that significantly influenced HPV vaccination intent. A higher proportion of participants expressed willingness to pay for 2vHPV (81.2%) and 4vHPV (75.9%), as compared to 9vHPV (67.7%).ConclusionAdults women expressed moderate intention to receive the HPV vaccine. Intervention to address barriers to uptake of the HPV vaccine among adult women in China is warranted.  相似文献

PurposeSeasonal influenza vaccination is recommended in children aged 6–59 months, but little is known about child vaccination coverage and determinants in Asian settings. We report the results of a survey of knowledge, attitudes, practices, and determinants of child influenza vaccination in Singapore.MethodsIn December 2015-March 2016, we conducted a survey of 332 parents of children aged 6 months to 5 years attending pre-schools. We assessed child influenza vaccine coverage and parental knowledge, attitudes, and practices of child influenza vaccination. We used multivariable regression and structural equation models to identify factors associated with child influenza vaccination.ResultsKnowledge about influenza, perceived benefit of vaccination, and willingness to vaccinate were high. However, only 32% of children had ever received influenza vaccine, and only 15% in the past year. Factors independently associated with child influenza vaccination included: being recommended influenza vaccine by a child’s doctor (prevalence ratio (PR) = 2.47, 95% CI: 1.75–3.48); receiving influenza vaccine information from a private general practitioner (PR = 1.47, 95% CI: 1.05–2.04); regularly receiving pre-travel influenza vaccine (PR = 1.64, 95% CI: 1.19–2.25); higher willingness to vaccinate (PR = 1.58, 95% CI:1.24–2.04 per unit increase in willingness score); and feeling well-informed about influenza vaccine (PR = 1.44, 95% CI: 1.04–1.99). Parents who obtained influenza vaccine information from television were less likely to have vaccinated their child (PR = 0.44, 95% CI: 0.23–0.85). Path analysis indicated that being recommended vaccination by a child's doctor increased willingness to vaccinate and self-efficacy (feeling well-informed about influenza vaccine). Median willingness-to-pay for a dose of influenza vaccine was SGD30 (interquartile range: SGD20-SGD50), and was higher in parents of vaccinated compared with unvaccinated children (SGD45 vs SGD30, p = 0.0012).ConclusionKnowledge and willingness to vaccinate was high in this parent population, but influenza vaccine uptake in children was low. Encouraging medical professionals to recommend vaccination of eligible children is key to improving uptake.  相似文献

BackgroundPublic polling indicates that vaccine uptake will be suboptimal when COVID-19 vaccines become available. Formative research seeking an understanding of weak vaccination intentions is urgently needed.MethodsNationwide online survey of 804 U.S. English-speaking adults. Compensated participants were recruited from the U.S. through an internet survey panel of 2.5 million residents developed by a commercial survey firm. Recruitment was based on quota sampling to produce a U.S. Census-matched sample representative of the nation with regard to region of residence, sex, and age.ResultsCOVID-19 vaccination intentions were weak, with 14.8% of respondents being unlikely to get vaccinated and another 23.0% unsure. Intent to vaccinate was highest for men, older people, individuals who identified as white and non-Hispanic, the affluent and college-educated, Democrats, those who were married or partnered, people with pre-existing medical conditions, and those vaccinated against influenza during the 2019–2020 flu season.In a multiple linear regression, significant predictors of vaccination intent were general vaccine knowledge (β = 0.311, p < .001), rejection of vaccine conspiracies (β = ?0.117, p = .003), perceived severity of COVID-19 (β = 0.273, p < .001), influenza vaccine uptake (β = 0.178, p < .001), having ≥ 5 pre-existing conditions (β = 0.098, p = .003), being male (β = 0.119, p < .001), household income of ≥ $120,000 (β = 0.110, p = .004), identifying as a Democrat (β = 0.075, p < .029), and not relying upon social media for virus information (β = -0.090, p 〈0 0 2). Intent to vaccinate was lower for Fox News (57.3%) than CNN/MSNBC viewers (76.4%) (χ2 (1) = 12.68, p < .001). Political party differences in threat appraisals and vaccine conspiracy beliefs are described.ConclusionsDemographic characteristics, vaccine knowledge, perceived vulnerability to COVID-19, risk factors for COVID-19, and politics likely contribute to vaccination hesitancy.  相似文献

BackgroundAustralia commenced a publically-funded, National Human Papillomavirus (HPV) Vaccination Program in 2007 with a two year catch-up phase for females aged 12–26 years.ObjectiveTo identify the factors associated with the uptake of the HPV vaccine (which has a recommended 3-dose schedule in Australia) by young adult women vaccinated by general practitioners and community-based programs within the catch-up phase.Methods1139 women who were eligible to receive the free HPV vaccine during the catch-up period were recruited in 2008–2009 (age 20–29 years at recruitment), in New South Wales, after having a normal (negative) cervical smear result recorded on the NSW Pap Test Register. Participants completed a self-administered questionnaire providing information on vaccination status, and sociodemographic and other factors.ResultsOverall, 880 (77%) women reported receiving ≥1 dose of the vaccine and 777 women (68%) reported receiving ≥2 doses. In multivariable analysis (adjusting for the period for which each woman was eligible for free HPV vaccination), uptake of ≥1 dose of the vaccine was significantly associated with being born in Australia (p < 0.01), being single (p = 0.02), being nulliparous (p < 0.01), living in a higher socioeconomic status area (p-trend = 0.03), living in more remote areas (p = 0.03), drinking alcohol (p < 0.01) and using hormonal contraceptives (p < 0.01). Although vaccinated women were more likely to have fewer sexual partners than unvaccinated women (p-trend = 0.02), they were also more likely to report a prior sexually transmitted infection (STI) (p = 0.03). Similar factors were associated with receiving ≥2 doses.ConclusionsIn this group, women living in higher socioeconomic status areas were more likely to be vaccinated against HPV in the catch-up phase of the national program. Although vaccinated women tended to have fewer sexual partners, they also reported prior STIs, which may be a marker of increased risk of prior exposure to HPV. The findings of this study reinforce the continuing need to prioritise equitable delivery of vaccination to various population subgroups.  相似文献
