Study protocol for a randomized controlled trial to assess the feasibility of an open label intervention to improve hydroxyurea adherence in youth with sickle cell disease. Contemp Clin Trials 2016; 49:134-42. [PMID: 27327779 DOI: 10.1016/j.cct.2016.06.004] [Citation(s) in RCA: 7] [Impact Index Per Article: 0.9] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/28/2016] [Revised: 06/10/2016] [Accepted: 06/16/2016] [Indexed: 12/26/2022]
Abstract
BACKGROUND Community health workers (CHW) are increasingly recognized as a strategy to improve health outcomes for the underserved with chronic diseases but has not been formally explored in adolescents with sickle cell disease (SCD). SCD primarily affects African American, Hispanic and other traditionally underserved populations. Hydroxyurea (HU), an oral, once-daily medication, is the only approved therapeutic drug for sickle cell disease and markedly reduces symptoms, morbidity and mortality and improves quality of life largely by increasing hemoglobin F blood levels. This paper presents the rationale, study design and protocol for an open label randomized controlled trial to improve parent-youth partnerships in self-management and medication adherence to HU in adolescents with SCD. METHODS/DESIGN A CHW intervention augmented by text messaging was designed for adolescents with SCD ages 10-18years and their parents to improve daily HU adherence. Thirty adolescent parent dyads will be randomized with 2:1 intervention group allocation. Intervention dyads will establish a relationship with a culturally aligned CHW to identify barriers to HU use, identify cues to build a habit, and develop a dyad partnership to improve daily HU adherence and achieve their individualized "personal best" hemoglobin F target. Intervention feasibility, acceptability and efficacy will be assessed via a 2-site trial. Outcomes of interest are HU adherence, dyad self-management communication, quality of life, and resource use. DISCUSSION Despite known benefits, poor HU adherence is common. If feasible and acceptable, the proposed intervention may improve health of underserved adolescents with SCD by enhancing long-term HU adherence. TRIAL REGISTRATION NCT02029742.

Human papillomavirus vaccine-related risk perceptions and subsequent sexual behaviors and sexually transmitted infections among vaccinated adolescent women. Vaccine 2016; 34:4040-5. [PMID: 27291086 DOI: 10.1016/j.vaccine.2016.06.026] [Citation(s) in RCA: 13] [Impact Index Per Article: 1.6] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/15/2016] [Revised: 05/27/2016] [Accepted: 06/03/2016] [Indexed: 01/26/2023]
Abstract
OBJECTIVE To examine the association between risk perceptions after human papillomavirus (HPV) vaccination and sexual behaviors and sexually transmitted infection (STI) diagnosis over 30months following vaccination. METHODS Participants included 112 sexually experienced girls aged 13-21years who were enrolled at the time of first HPV vaccination and completed ⩾2 of 4 follow-up visits at 2, 6, 18, 30months and including 30months. At each visit, participants completed surveys assessing risk perceptions (perceived need for safer sexual behaviors, perceived risk of STIs other than HPV) and sexual behaviors. STI testing was done at 6, 18, and 30months. Outcomes were condom use at last intercourse with main male partner, number of sexual partners since last study visit, and STI diagnosis. Associations between risk perceptions and sexual behaviors/STIs were examined using generalized linear mixed models. RESULTS Mean age was 17.9years; 88% were Black; 49% had a history of STI at baseline. Scale scores for perceived need for safer sexual behaviors did not change significantly over time. Scale scores for perceived risk of STIs other than HPV significantly changed (p=0.027), indicating that girls perceived themselves to be more at risk of STIs other than HPV over 30months following vaccination. Multivariable models demonstrated that greater perceived need for safer sexual behaviors following vaccination was associated with condom use (p=0.002) but not with number of partners or STI diagnosis. Perceived risk of STIs other than HPV was not associated with the three outcomes. CONCLUSIONS The finding that perceived risk for STIs other than HPV was not associated with subsequent sexual behaviors or STI diagnosis is reassuring. The association between perceived need for safer sexual behaviors and subsequent condom use suggests that the HPV vaccination visit is an important opportunity to reiterate the importance of safer sexual behaviors to sexually experienced girls.

Abstract
STUDY OBJECTIVE To understand how adolescents and parents describe a sexually transmitted infection prevention study to a friend. DESIGN Adolescents and parents participating in a study about willingness to participate in a hypothetical microbicide clinical trial were interviewed separately and asked to describe the clinical trial to a friend. Qualitative responses were written down verbatim and coded using a thematic framework analysis. SETTING Adolescent medicine clinics in New York City. PARTICIPANTS The participants consisted of adolescents, 14-17 years old, and a parent (n = 301 dyads) who spoke English or Spanish. Most adolescents (72%) identified as Hispanic and 65% reported minimal sexual experience (ie, nothing more than kissing). INTERVENTIONS None. MAIN OUTCOME MEASURES Qualitative responses were content coded for: (1) overall approach; (2) opinion rendered; and (3) details mentioned using thematic framework. The relationship of demographic characteristics, sexual history, and recruitment method to how adolescents and/or parents described the study was evaluated. RESULTS Adolescents (n = 293) differed from parents (n = 298) in their overall approach to describing the study (P < .01) with more adolescents than parents providing a "purpose with detail" (54% adolescents vs 31% parents) and less providing a "commentary" description (6% adolescents vs 28% parents). Fewer adolescents (25% of n = 301) provided an opinion compared with parents (75% of n = 301; P < .01). A greater proportion of adolescents (70% adolescents, n = 206; vs 48% parents, n = 144) provided a detail (P < .01). Adolescents provided a greater number of details than parents (P < .01). CONCLUSION Adolescents in this sample were more focused on the details of the study. Parents were focused on their impression of the study. Adolescents and parents might need to be approached differently about reproductive health studies.

Abstract
PURPOSE Despite their heightened risk of sexually transmitted infections, minor adolescents (<18 years old) are often excluded from clinical trials. The results of trials of adults should not be assumed to generalize to minors. METHODS Two public clinical trial registries were first searched using microbicide or PrEP with STD, STI, HIV, or HSV and with gel, ring, or film, and then searched using prevention/sexually transmitted diseases with gel. Studies were classified based on the information provided in the registry. RESULTS The searches yielded 111 unique studies. Only 9.0% (n = 10) included minors. They were under-represented in Phase 0-II studies and over-represented in studies of individuals infected with human immunodeficiency virus. CONCLUSIONS Minor adolescents should be included during all stages of development and before they have acquired an infection. Future studies should examine the challenges of including minor adolescents in trials and how to overcome these barriers.

Abstract
IMPORTANCE The quadrivalent human papillomavirus (HPV) vaccine was licensed for use in 9- through 26-year-old females in 2006. Postlicensure studies in Australia, Denmark, and Canada have demonstrated vaccine effectiveness against abnormal cervical cytology results. However, there are limited data describing postlicensure effectiveness in the United States, particularly among minority females at higher risk for HPV infection and cervical cancer. OBJECTIVE To examine the effect of HPV vaccination on abnormal cervical cytology results among minority females. DESIGN, SETTING, AND PARTICIPANTS Retrospective cohort study conducted between January 2007 and January 2014 at 16 academically affiliated community clinics serving a low-income minority population. Included in this study was a population-based sample of 16 266 females aged 11 through 20 years as of January 1, 2007, who received care at a participating clinic on or after that date. EXPOSURE Human papillomavirus vaccination, stratified by the number of doses. MAIN OUTCOMES AND MEASURES Cervical cytology abnormality following either HPV vaccination or, if unvaccinated, the first missed opportunity for HPV vaccination after January 1, 2007. Abnormalities were defined as atypical glandular cells, atypical squamous cells of undetermined significance, atypical squamous cells, cannot exclude a high-grade squamous intraepithelial lesion, low-grade squamous intraepithelial lesions, or high-grade squamous intraepithelial lesions. RESULTS There were 4127 female patients who initiated quadrivalent HPV vaccination or had their first missed HPV vaccination opportunity from 11 through 20 years of age and underwent subsequent cervical cytology screening. The patients were primarily Spanish speaking (n = 2297; 58.3%) and publicly insured (n = 3801; 92.1%). The detection rate for an abnormal cervical cytology result during the observation period was lower among vaccinated (≥1 dose) (79.1 per 1000 person-years) vs unvaccinated (125.7 per 1000 person-years) females. The risk for an abnormal cervical cytology result was lower among vaccinated vs unvaccinated females (hazard ratio [HR], 0.64; 95% CI, 0.57-0.73), particularly if the 3-dose series was completed (HR, 0.48; 95% CI, 0.41-0.56) or if the vaccine was administered from 11 through 14 years of age (≥1 dose: HR, 0.36; 95% CI, 0.16-0.79; 3 doses: HR, 0.27; 95% CI, 0.12-0.63). This protective effect remained after adjusting for demographics, clinic type, abnormal baseline cervical cytology result, and baseline Chlamydia screening (as proxy for sexual experience). CONCLUSIONS AND RELEVANCE This study demonstrated the HPV vaccine is effective in a real-world setting of high-risk patients with variable HPV vaccination patterns.

Abstract
Adolescents with chronic medical conditions (CMCs), a growing population worldwide, possess a wide array of preventive health care needs. Vaccination is strongly recommended for the vast majority of these adolescents given their increased risk of vaccine preventable infection and associated complications. Not only should they receive routine vaccines, but some also require additional vaccines. Despite these guidelines, evidence suggests that adolescents with CMCs often fail to receive needed vaccines. Many factors contribute to this under-immunization, including lack of knowledge among parents and providers and suboptimal coordination of primary and subspecialty care. This review describes current vaccination recommendations for these adolescents as well as recent data related to infection risk, vaccine efficacy and safety, vaccination coverage, and the unique multilevel factors impacting uptake in this population. It also discusses strategies for improving coverage levels and reducing missed vaccination opportunities, with a particular focus on technology-based interventions.

Abstract
Osteoporosis and hemochromatosis are both late-onset preventable diseases, but future genetic tests for these conditions are likely to differ in their predictive abilities. To determine whether interest in a specific genetic test for hemochromatosis would be higher than interest in a theoretical test for osteoporosis susceptibility, undergraduate women at the University of Cincinnati (N = 181) were surveyed regarding their interest in genetic testing for these conditions. The clinical features of the diseases and the limits of a genetic test for each were described. Sixty-three percent of the total population was interested in genetic testing with a trend toward higher interest in the osteoporosis group. Disease familiarity, perceived disease severity, and perceived risk for disease appear to be more important predictors of genetic test acceptance than diagnostic specificity. Suggested implications for the development of population genetic screening tests are discussed.

Abstract
OBJECTIVES Among 11-12 year-old girls who received the human papillomavirus (HPV) vaccine, we explored, over the subsequent 30 months: (1) trajectories of knowledge about HPV/HPV vaccines and vaccine-related risk perceptions; (2) whether knowledge and risk perceptions impacted sexual attitudes and sexual experience; (3) whether mothers, clinicians, and media influenced girls' risk perceptions, attitudes, and behavior. METHODS Girls and mothers (n=25dyads) completed separate, semi-structured interviews within 2 days of, and 6, 18, and 30 months after, their first HPV vaccine dose. Knowledge, risk perceptions related to HPV and other sexually transmitted infections (STIs), and attitudes about sexual behaviors were assessed. Sexual experience was assessed at girls' 30 month interviews. Clinicians completed interviews at baseline. Transcribed interviews were analyzed using framework analysis. RESULTS Girls' baseline knowledge was poor but often improved with time. Most girls (n=18) developed accurate risk perceptions about HPV but only half (n=12) developed accurate risk perceptions about other STIs by 30 months. The vast majority of girls thought that safer sex was still important, regardless of knowledge, risk perceptions, or sexual experience. Girls whose HPV knowledge was high at baseline or increased over time tended to articulate accurate risk perceptions; those who were able to articulate accurate risk perceptions tended to report not having initiated sexual activity. Girls whose mothers demonstrated higher knowledge and/or communication about HPV vaccination tended to articulate accurate risk perceptions, whereas clinicians and media exposure did not appear to influence risk perceptions. CONCLUSIONS Higher knowledge about HPV vaccines among mothers and girls was linked with more accurate risk perceptions among girls. Clinicians may play an important role in providing education about HPV vaccines to mothers and girls.

Abstract
Altruism is a well-established reason underlying research participation. Less is known about altruism in adolescent-parent decision-making about clinical trials enrolling healthy adolescents. This qualitative investigation focused on identifying spontaneous statements of altruism within adolescent-parent (dyadic) discussions of participation in a hypothetical phase I clinical trial related to adolescent sexual health. Content analysis revealed several response patterns to each other's altruistic reasoning. Across 70 adolescent-parent dyads in which adolescents were 14-17 years of age and 91% of their parents were mothers, a majority (61%) of dyadic discussions included a statement reflecting altruism. Parents responded to adolescents' statements of altruism more frequently than adolescents responded to parents' statements. Responses included: expresses concern, reiterates altruistic reasoning, agrees with altruistic reasoning, and adds to/expands altruistic reasoning. Since an altruistic perspective was often balanced with concerns about risk or study procedures, researchers cannot assume that altruism will directly lead to study participation. Optimizing the informed consent process for early phase clinical trials involving healthy adolescents may include supporting parents to have conversations with their adolescents which will enhance their capacity to consider all aspects of trial participation.

Abstract
BACKGROUND AND OBJECTIVES Early first sexual intercourse (FSI) is a risk factor for unplanned teenage pregnancy, sexually transmitted infection, and adverse social, emotional, and physical health outcomes in adolescence and into adulthood. The aim of this study was to examine relationships between internalizing (eg, anxious/depressed, withdrawn) and externalizing (eg, delinquent, aggressive) behavior problems in childhood and age at FSI. METHODS We used a large, population-based birth cohort (The Western Australian Pregnancy Cohort [Raine] Study) to address this question. Child behavior was measured by using the Child Behavior Checklist collected from parents at ages 2, 5, 8, 10, and 14 and scores calculated for total, internalizing, and externalizing behavior problems. At age 17, 1200 participants reported sexual behavior. RESULTS Participants with clinically significant Child Behavior Checklist scores (T ≥ 60) were at increased risk for earlier first sexual intercourse (FSI) (<16 years). Adjusted odds ratios revealed that total and externalizing behavior problems from age 5 years onward significantly increased the risk of earlier FSI for boys. In girls, externalizing problems from age 10 years increased the risk for earlier FSI. Internalizing problems at ages 8 and 10 were significantly associated with early FSI for boys but not girls. CONCLUSIONS Externalizing behavior from as early as 5 in boys and 10 in girls is a significant risk factor for earlier age at FSI. Adolescent sexual health promotion should consider early intervention in children with behavior problems, particularly boys.

Abstract
Adolescent immunization rates for human papillomavirus (HPV) are low and interventions within school-based health centers (SBHCs) may increase HPV uptake and series completion. We examined the effect of a parent health message intervention on HPV vaccination intent, first dose uptake and series completion among adolescents who received care at SBHCs. Via computer-assisted telephone interviews (CATI), 445 parents of young adolescents were randomly assigned to 2 two-level interventions using a 2 × 2 design (rhetorical question (RQ) or no-RQ and one-sided or two-sided message). The RQ intervention involved asking the parent a question they were likely to endorse (e.g., "Do you want to protect your daughter from cervical cancer?") with the expectation that they would then behave in a manner consistent with their endorsement (i.e., agree to vaccinate). For the one-sided message, parents were given information that emphasized the safety and effectiveness of HPV vaccine, whereas the two-sided message acknowledged that some parents might have concerns about the vaccine, followed by reassurance regarding the safety and effectiveness. At CATI conclusion, parents indicated intentions to have their adolescents vaccinated. Parents who endorsed any intent were sent a consent form to return and all adolescents with signed returned consents were vaccinated at SBHCs. Medical records were reviewed for uptake/completion. Parents were 87% female; adolescents were 66% male and racially/ethnically diverse. 42.5% of parents indicated some intention to immunize, 51.4% were unsure, and 6.1% were not interested. 34% (n = 151) of adolescents received their first dose with series completion rates of 67% (n = 101). The RQ component of the intervention increased intention to vaccinate (RR = 1.45; 95%CI 1.16,1.81), but not first dose uptake or series completion. The 1-sided and 2-sided messages had no effect. This brief, RQ health intervention enhanced intent, but did not impact vaccination rates, likely due to the time delay between the intervention and consent form receipt.

Abstract
INTRODUCTION Sexually active adolescent and adult men have substantial sexual and reproductive health (SRH) needs, but little is known about their willingness and preferred approach to talk about SRH with their healthcare provider. PURPOSE To examine participants' willingness to talk about 11 SRH topics, including sexually transmitted disease (STD) risk; human papilloma virus (HPV) vaccine; condom use; female birth control methods; emergency contraception; concerns about sexual performance or making someone pregnant; being a father; relationships; testicular cancer; and acne, with their healthcare provider and their preferred approach (provider- or self-initiated). METHODS This cross-sectional clinic-based survey of 346 men aged 16-35 years was conducted in 2011. Bivariate analyses conducted in 2012 examined variation in study outcomes by participants' predisposing (age, race/ethnicity); enabling (education, past provider SRH discussion); and need factors (SRH concern). RESULTS Almost all participants (84%-98%) were willing to talk about all SRH topics. The top three topics included STD risk (98%); testicular cancer (98%); and HPV vaccine (97%). Among those willing to talk, the majority preferred their provider initiate the discussion (52%-88%). Participants reporting past provider discussions were more likely to prefer that their provider initiate discussions on condom use, female birth control methods, concerns about sexual performance and making someone pregnant, and relationships. Study outcomes did not vary by any other participant predisposing, enabling, or need factors. CONCLUSIONS These findings indicate that adolescent and adult men are willing to discuss a wide range of SRH topics with their healthcare provider. Providers need to move beyond whether male patients want to talk about these topics and instead proactively promote these conversations.

Abstract
HPV infection leads to significant morbidity and mortality worldwide. The HPV vaccine is currently licensed and recommended for adolescents and young adults in many countries. Nonetheless, coverage levels remain low, especially in settings using a clinic-based rather than school-based delivery model. Health care professionals (HCPs) have the potential to strongly impact HPV vaccine acceptability and uptake, yet often fail to discuss and/or strongly recommend HPV vaccination. This article reviews the myriad factors that influence HPV vaccination, focusing, in particular, on those relevant to HCP communication with patients and families. It also provides a historical framework and highlights recent evidence related to HPV vaccination that may be valuable for these conversations. Lastly, it discusses strategies targeting HCPs and their practices that may increase HPV vaccination initiation and completion rates globally.

Abstract
OBJECTIVES Concerns have been raised that human papillomavirus (HPV) vaccination could lead to altered risk perceptions and an increase in risky sexual behaviors among adolescents. The aim of this study was to assess whether adolescent risk perceptions after the first vaccine dose predicted subsequent sexual behaviors. METHODS Young women 13 to 21 years of age (N = 339) completed questionnaires immediately after HPV vaccination, and 2 and 6 months later, assessing demographic characteristics, knowledge/attitudes about HPV vaccination, risk perceptions, and sexual behaviors. Risk perceptions were measured by using 2 5-item scales assessing: (1) perceived risk of sexually transmitted infections (STI) other than HPV, and (2) perceived need for safer sexual behaviors after HPV vaccination. We assessed associations between risk perceptions at baseline and sexual behaviors over the next 6 months by using logistic regression, stratifying participants by sexual experience at baseline and age (13-15 vs. 16-21 years). RESULTS Among all sexually inexperienced participants (42.5%), baseline risk perceptions were not associated with subsequent sexual initiation; in age-stratified analyses, girls 16 to 21 years of age who reported lower perceived risk for other STI (an inappropriate perception) were less likely to initiate sex (odds ratio [OR] 0.13, 95% confidence interval [CI] 0.03-0.69). Among all sexually experienced participants (57.5%) and in age-stratified analyses, baseline risk perceptions were not associated with subsequent number of sexual partners or condom use. CONCLUSIONS Risk perceptions after HPV vaccination were not associated with riskier sexual behaviors over the subsequent 6 months in this study sample.

Hofstetter AM, Stockwell MS, Al-Husayni N, Ompad D, Natarajan K, Rosenthal SL, Soren K. HPV vaccination: are we initiating too late? Vaccine 2014; 32:1939-45. [PMID: 24530404 DOI: 10.1016/j.vaccine.2014.01.084] [Citation(s) in RCA: 14] [Impact Index Per Article: 1.4] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/23/2013] [Revised: 01/27/2014] [Accepted: 01/30/2014] [Indexed: 12/01/2022]
Abstract
BACKGROUND Human papillomavirus (HPV) vaccination is recommended in early adolescence. While limited data suggest that patients frequently delay initiation of the three-dose series, age-based variability in initiation of HPV vaccination and its clinical relevance are not well described. Thus, this study aims to characterize HPV vaccination delay among adolescent and young adult females. METHODS This retrospective cohort study examined age at HPV vaccination initiation and missed opportunities for receipt of the first vaccine dose (HPV1) among 11-26 year-old females (n=22,900) receiving care at 16 urban academically-affiliated ambulatory care clinics between 2007 and 2011. Predictors of timely vaccination and post-licensure trends in age at HPV1 receipt were assessed using multivariable logistic regression and a generalized linear mixed model, respectively. Chlamydia trachomatis and Papanicolaou screening before HPV vaccination initiation, as markers of prior sexual experience and associated morbidity, were examined in a subcohort of subjects (n=15,049). RESULTS The proportion of 11-12 year-olds who initiated HPV vaccination increased over time (44.4% [2007] vs. 74.5% [2011], p<0.01). Initiation rates also improved among 13-26 year-olds. Thus, the mean age at HPV1 receipt remained unchanged between 2007 and 2011 (16.0 ± 2.7 vs. 15.9 ± 4.0 years, p=0.45). Spanish language was a positive predictor (AOR 1.62, 95% CI 1.05-2.48) of HPV vaccination initiation among 11-12 year-olds in 2011. The majority (70.8-76.4%) of unvaccinated subjects experienced missed vaccination opportunities. Of the subcohort, 36.9% underwent Chlamydia screening before HPV1 receipt (19.1% with ≥ 1 positive result). Of those with prior Papanicolaou screening (16.6%), 32.1% had ≥ 1 abnormal result. CONCLUSIONS These low-income, minority females frequently delayed initiation of HPV vaccination. Many had evidence of prior sexual experience and associated morbidity, placing them at risk of HPV-related complications. Promoting timely HPV vaccination and reducing missed vaccination opportunities are crucial.

Abstract
STUDY OBJECTIVE Genital herpes, which can be spread through oral sex, is an important target for microbicides. We examined episode-specific predictors of young women's receptive oral sex and of microbicide surrogate use. DESIGN Longitudinal study. SETTING Participants were recruited to participate in a microbicide acceptability study from adolescent clinics and local colleges and through snowballing. PARTICIPANTS Young women (ages 14 to 21 y) who reported sexual contact on at least 1 weekly phone interview (n = 181) were included from the larger sample of 208 young women. MAIN OUTCOME MEASURES On weekly diary phone interviews, participants reported whether or not their last sexual contact included receptive oral sex and whether or not their last sexual contact included use of a microbicide surrogate. RESULTS AND CONCLUSIONS Participants reported a total of 1042 episodes of sexual contact of which 311 included receptive oral sex and 354 included microbicide surrogate use. Being older, having sex for the first time with a partner, and having given oral sex were associated with having received oral sex during a sexual episode. Being older, being African American, and having discussed the microbicide surrogate with their partner were associated with having used the microbicide surrogate use during a sexual episode. These results indicate that oral sex should be considered in the design of clinical trials. Future studies need to evaluate ways to promote consistent microbicide use in the context of receiving oral sex as well as those factors (eg, taste, pleasure) which may serve as a barrier.

Abstract
Little is known about adolescent males and their parents with respect to intent and first dose uptake of the human papillomavirus (HPV) vaccine outside of primay care settings. The purpose of this study was to evaluate potential predictors of parental intent to vaccinate (study was conducted in November 2010-December 2012) and of first dose uptake of HPV vaccine among a sample of young adolescent males, 11-15 years of age, who received care at a school-based health center (SBHC). We also examined intent as a potential mediator of the relationships between predictors (health beliefs and perceived spousal agreement) and vaccination. Slightly more than half (n=135 of 249) of parents reported an intention to vaccinate and 28% (n=69) of males received their first dose of the HPV vaccine. Two of three health beliefs were significantly associated with both intention and uptake as was perceived spousal agreement. We found intention to vaccinate was a partial mediatator between the perceived benefits of HPV vaccine and first dose acceptance. We also determined that intent was a strong mediator between both general immunization benefits and perceived spousal agreement and first dose uptake. While vaccine uptake was lower than expected, particularly considering that many barriers to vaccine initiation were eliminated because of the SBHC setting, this rate is higher than in traditional settings. After controlling for intent, only perceived benefits of the HPV vaccine remained a significant predictor of first dose acceptance.

Abstract
UNLABELLED Background Bacterial vaginosis (BV) is the most common reproductive tract infection (RTI) and is a significant risk factor for preterm birth. Microbicides could be an option for the prevention and treatment of BV in pregnancy, and understanding use of the product will be crucial. The present study explored attitudes of women in the third trimester of pregnancy regarding topical microbicide use for the prevention and treatment of BV. METHODS Twenty-six women in their third trimester were interviewed regarding their knowledge and beliefs about RTIs during pregnancy and attitudes concerning the use of topical microbicides for prevention and treatment of BV. RESULTS Participants had a mean age of 24.9 years, were largely under-represented minorities and the majority had had past pregnancies. Participants had knowledge and experience with RTIs but not BV. They were open to the use of microbicides for prevention or treatment of BV, but believed that women requiring treatment would be more motivated. Rationales for acceptability were most commonly related to the baby's health. Practical issues that may interfere with use were often, but not always, related to pregnancy. There was a range of attitudes about partner involvement in decision-making and the practicalities of product use. CONCLUSION Pregnant women are knowledgeable about RTIs but not necessarily BV. The women in this study found microbicide use acceptable, particularly for treatment. To improve acceptability and use, education would be needed about BV and possible complications, how to overcome practical problems and the value of involving partners in the decision.

Abstract
OBJECTIVE Younger age at menarche (AAM) may put girls at risk for earlier first sexual intercourse (FSI). Young age at FSI has far-reaching negative outcomes. We describe the longitudinal relationship between AAM and FSI in a large prospective birth cohort. METHODS AAM was collected from 554 girls from the Western Australia (Raine) Pregnancy Cohort Study, prospectively from age 10 or retrospectively at age 14. Age at FSI was collected at ages 17 and 20. Cox regression models describe likelihood of FSI by age and years since menarche for younger (<12 years) and older (≥14 years) AAM relative to average AAM (12-13 years). RESULTS Girls with younger AAM and average AAM were equally likely to have FSI by age 16 (adjusted hazard ratio [aHR]: 0.90 [95% confidence interval (CI): 0.60-1.35]). FSI by age 16 was less likely among girls with older AAM than those with average AAM (aHR: 0.35 [95% CI: 0.17-0.72]). Girls with younger AAM had a longer median interval between menarche and FSI than girls with average AAM (5.0 years [interquartile range: 4.4-8.5 years] vs 3.7 years [interquartile range: 2.4-5.3 years]). Those with younger AAM were less likely to report FSI within 4 years of menarche than those with average AAM (0-2 years aHR: 0.04 [95% CI: 0.01-0.31]; 2-4 years aHR: 0.36 [95% CI: 0.23-0.55]). By age 20, 429 girls (77.4%) reported FSI. CONCLUSIONS Younger AAM was not a risk factor for younger age at FSI in this cohort.

Abstract
OBJECTIVES Because little is known about the content of human papillomavirus (HPV) vaccine-related discussions with young adolescent girls in clinical settings, we explored communication between 11- and 12 year-old girls, mothers, and clinicians regarding HPV vaccines and concordance in reports of maternal and clinician communication. METHODS We conducted individual interviews with 33 girls who had received the quadrivalent HPV vaccine in urban and suburban clinical settings, their mothers, and their clinicians. Data were analyzed using qualitative methods. RESULTS From the perspectives of both girls and mothers, clinicians and parents were the preferred sources of HPV vaccine information for girls. Vaccine efficacy and risks/benefits of vaccination were the most commonly reported desired and actual topics of discussion by mothers, girls, and clinicians. Clinician recommendation of vaccination was reported by nearly one-fifth of girls and nearly half of mothers. The most common concordant messages were related to efficacy of the vaccine, with concordance in 70% of triads. The most common discordant messages were related to sexual health. Approximately half of clinicians (16) reported discussing sexual health, but only 5 mothers (15%) and 4 girls (12%) reported this. Triads recruited from suburban (vs. urban) practices had higher degrees of concordance in reported vaccination communication. CONCLUSIONS HPV vaccine efficacy and safety are important topics for clinicians to discuss with both girls and mothers; educating mothers is important because parents are a preferred source of vaccine-related information for girls. Because girls may be missing important vaccine-related messages, they should be encouraged to actively engage in vaccine discussions.

Abstract
OBJECTIVE The aims of this study were to examine pre-existing videos in order to explore the motivation for, possible approaches to, and timing and context of disclosure of genital herpes infection as described by the lay public. METHODS A thematic content analysis was performed on 63 videos submitted to an Australian online contest sponsored by the Australian Herpes Management Forum and Novartis Pharmaceuticals designed to promote disclosure of genital herpes. RESULTS Videos either provided a motivation for disclosure of genital herpes or directed disclosure without an explicit rationale. Motivations included manageability of the disease or consistency with important values. Evaluation of strategies and logistics of disclosure revealed a variety of communication styles including direct and indirect. Disclosure settings included those that were private, semiprivate and public. Disclosure was portrayed in a variety of relationship types, and at different times within those relationships, with many videos demonstrating disclosure in connection with a romantic setting. CONCLUSIONS Individuals with genital herpes are expected to disclose to susceptible partners. This analysis suggests that understanding lay perspectives on herpes disclosure to a partner may help healthcare providers develop counselling messages that decrease anxiety and foster disclosure to prevent transmission.
