HPV vaccination and sexual behaviour in healthcare seeking young women in Luxembourg.

ABSTRACT: Introduction:Human papillomavirus (HPV) is the most common sexually transmitted infection (STI) worldwide. Despite recommendations for HPV vaccination of young women from health authorities, parental concerns were raised whether vaccination could induce unsafe sexual behaviour in young women. Therefore, the primary aim of this study was to investigate if HPV vaccination in healthcare seeking adult women in Luxembourg was associated with unsafe sexual behaviour. Methods:Seven hundred twenty-nine women (mean age = 22.5; range 18-43 years) were recruited either at Luxembourg family planning centres or at private gynaecology practices. All participants completed a questionnaire on vaccination status and sexual behaviour. Poisson and logistic regressions were used to study the association between sexual behaviour and vaccination status (N = 538). Both models were restricted to women younger than 26 years, since the first cohort being vaccinated would be 25 years old at the time of sampling. Assortativity of sexual mixing by age was also assessed for further transmission modelling for women <30 years reporting age of last/current sexual partner (N = 649). Women older than 29 years were excluded from the assortativity analysis due to restricted sample size. Results:In total, 386/538 (71.8%) of participants reported receiving HPV vaccine. Vaccination uptake significantly varied by nationality and was higher in Portuguese 112/142 (78.9%) and in Luxembourgish 224/313(71.6%) residents, and lower in residents of other nationalities 50/83 (60.2%) (p = 0.011). HPV vaccination was not associated with unsafe sexual behaviour such as shorter relationship duration with current or last sexual partner (odds ratio (OR) = 1.05, 95% CI [0.94-1.16]), younger age of sexual debut (OR = 1.00, 95% CI [0.88-1.14]), increased number of lifetime sexual partners (OR = 0.95, 95% CI [0.87-1.03), higher age difference with sexual partner (OR = 1.01, 95% CI [0.95-1.08]), condom use (OR = 0.97, 95% CI [0.60-1.56]), nor with other factors like smoking (OR = 0.73, 95% CI [0.47-1.15]) and nationality. HPV vaccination was only associated with younger age (OR = 0.84, 95% CI [0.75-0.94]). Relationship duration, age of sexual debut, age difference with sexual partner, smoking, age and non-Portuguese foreign nationality were predictors of number of lifetime sexual partners. Assortativity analysis revealed that young women chose sexual partners who were 2.3 years older on average. Conclusions:Our study found no association between unsafe sexual behaviour and HPV vaccination.

Project description:BackgroundWhile prophylactic human papilloma virus (HPV) vaccination is considered effective in young girls, it is unclear whether a catch-up vaccination of older girls would be beneficial. We, therefore, aimed to examine the potential health impact of a HPV catch-up vaccination of girls who were too old at the time of vaccine introduction, hence aged 16 and older.MethodsWe systematically searched the literature for randomized clinical trials (RCTs) that examined the effect of HPV vaccines on overall mortality, cancer mortality and incidence, high-grade cervical intraepithelial neoplasia grade 2 and higher (CIN2+), vulvar intraepithelial neoplasia (VIN) and vaginal intraepithelial neoplasia (VaIN) grade 2 and higher lesions (VIN2+ and VaIN2+, respectively) genital warts (condyloma). We considered all lesions and those associated with HPV type(s) included in the vaccines. RCTs reporting on serious adverse events were also eligible. Selected publications were assessed for potential risk of bias, and we ascertained the overall quality of the evidence for each outcome using Grading of Recommendations Assessment, Development and Evaluation (GRADE). Meta-analyses were performed, assuming both random and fixed effects, to estimate risk ratios (RR) and corresponding 95% confidence intervals (CI), using intention-to-treat and per-protocol populations.ResultsWe included 46 publications reporting on 13 RCTs. Most of the RCTs had a maximum follow-up period of four years. We identified no RCT reporting on the effect of HPV catch vaccination on overall and cancer related mortality, and on cervical cancer incidence. We found a borderline protective effect of a HPV catch-up vaccination on all CIN2+, with a pooled RR of 0.80 (95% CI: 0.62-1.02) for a follow-up period of 4 years. A HPV catch-up vaccination was associated with a reduction in VIN2+ and VaIN2+ lesions, and condyloma. No difference in risk of serious adverse events was seen in vaccinated participants versus unvaccinated women (pooled RR of 0.99 (0.91-1.08)).ConclusionsThis systematic review indicates that a HPV catch-up vaccination could be beneficial, however the long-term effect of such a vaccination, and its effect on cervical cancer incidence and mortality is still unclear.

Project description:In 2012, human papillomavirus (HPV) vaccination was introduced free of charge in the Swedish national school-based vaccination programme for 10-12-year-old girls, and as catch-up vaccination for young women. In Sweden, there is an ongoing discussion about including boys in the national vaccination programme. Few studies are undertaken about adolescents' knowledge, beliefs and HPV vaccination status in relation to socioeconomic status and sexual experience. Thus, the aim was to examine HPV catch-up vaccination status in adolescents in relation to 1) socioeconomic factors, 2) beliefs and knowledge about HPV prevention, and 3) sexual behaviour. The Health Belief Model was used as a theoretical framework. Upper secondary school students (n = 832) aged 16, randomly chosen from a larger sample, were invited to participate in conjunction with the general health interview with the school nurse. A total of 751/832 (90.3%), girls (n = 391, 52%) and boys (n = 360, 48%) completed the questionnaire. HPV vaccination was associated with ethnicity and the mothers' education level; i.e. girls with a non-European background and girls with a less educated mother were less likely to have received the vaccine (p<0.01 and p = 0.04 respectively). Vaccinated girls perceived HPV infection as more severe (p = 0.01), had more insight into women's susceptibility to the infection (p = 0.02), perceived more benefits of the vaccine as protection against cervical cancer (p<0.01) and had a higher intention to engage in HPV-preventive behaviour (p = 0.01). Furthermore, boys and girls were almost equally sexually experienced, although fewer girls had used condom during first intercourse with their latest partner (p = 0.03). Finally, HPV vaccinated girls were less likely to have unprotected sex (p<0.01). In summary, catch-up HPV vaccination among young girls was associated with a European background and high maternal education level, as well as more favourable beliefs towards HPV prevention and less sexual risk-taking. Further preventive measures should therefore be directed at the migrant population.
