Abstract
The primary goal of antiretroviral treatment is to improve the health of individuals with HIV, and a secondary goal is to prevent further transmission. In 2016, Rwanda adopted the World Health Organization's "treat-all" approach in combination with the differentiated service delivery (DSD) model. The model's goal was to shorten the time from HIV diagnosis to treatment initiation, regardless of the CD4 T-cell count. This study sought to identify perceptions, enablers, and challenges associated with DSD model adoption among PLHIV.This study included selected health centers in Kigali city, Rwanda, between August and September 2022. The patients included were those exposed to the new HIV care model (DSD) model and those exposed to the previous model who transitioned to the current model. Interviews and focus group discussions were also held to obtain views and opinions on the DSD model. The data were collected via questionnaires and audio-recorded focus group discussions and were subsequently analyzed.The study identified several themes, including participants' initial emotions about a new HIV diagnosis, disclosure, experiences with transitioning to the DSD model, the effect of peer education, and barriers to and facilitators of the DSD model. Participants appreciated reduced clinic visits under the DSD model but faced transition and peer educator mobility challenges.The DSD model reduces waiting times, educates patients, and aligns with national goals. Identified barriers call for training and improved peer educator retention. Recommendations include enhancing the DSD model and future research to evaluate its long-term impact and cost-effectiveness.

A conceptual analysis of SBIRT implementation alongside the continuum of PrEP awareness: domains of fit and feasibility. Front Public Health 2024; 11:1310388. [PMID: 38259734 PMCID: PMC10801388 DOI: 10.3389/fpubh.2023.1310388] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/09/2023] [Accepted: 12/12/2023] [Indexed: 01/24/2024] Open
Abstract
Screening, Brief Intervention, and Referral to Treatment (SBIRT) is a supplementary intervention that can be incorporated into the Pre-Exposure Prophylaxis (PrEP) Care Continuum, complementing initiatives and endeavors focused on Human Immunodeficiency Virus (HIV) prevention in clinical care and community-based work. Referencing the Transtheoretical Model of Change and the PrEP Awareness Continuum, this conceptual analysis highlights how SBIRT amplifies ongoing HIV prevention initiatives and presents a distinct chance to address identified gaps. SBIRT's mechanisms show promise of fit and feasibility through (a) implementing universal Screening (S), (b) administering a Brief Intervention (BI) grounded in motivational interviewing aimed at assisting individuals in recognizing the significance of PrEP in their lives, (c) providing an affirming and supportive Referral to Treatment (RT) to access clinical PrEP care, and (d) employing client-centered and destigmatized approaches. SBIRT is uniquely positioned to help address the complex challenges facing PrEP awareness and initiation efforts. Adapting the SBIRT model to integrate and amplify HIV prevention efforts merits further examination.

Uptake of an app-based case management service for HIV-positive men who have sex with men in China: a process evaluation study (Preprint). J Med Internet Res 2022; 25:e40176. [PMID: 37099367 PMCID: PMC10173030 DOI: 10.2196/40176] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/09/2022] [Revised: 01/15/2023] [Accepted: 02/24/2023] [Indexed: 02/26/2023] Open
Abstract
BACKGROUND Men who have sex with men (MSM) in China are disproportionately affected by the HIV epidemic, and medication adherence to antiretroviral treatment in this vulnerable population is suboptimal. To address this issue, we developed an app-based case management service with multiple components, informed by the Information Motivation Behavioral skills model. OBJECTIVE We aimed to conduct a process evaluation for the implementation of an innovative app-based intervention guided by the Linnan and Steckler framework. METHODS Process evaluation was performed alongside a randomized controlled trial in the largest HIV clinic in Guangzhou, China. Eligible participants were HIV-positive MSM aged ≥18 years planning to initiate treatment on the day of recruitment. The app-based intervention had 4 components: web-based communication with case managers, educational articles, supportive service information (eg, information on mental health care and rehabilitation service), and hospital visit reminders. Process evaluation indicators of the intervention include dose delivered, dose received, fidelity, and satisfaction. The behavioral outcome was adherence to antiretroviral treatment at month 1, and Information Motivation Behavioral skills model scores were the intermediate outcome. Logistic and linear regression was used to investigate the association between intervention uptake and outcomes, controlling for potential confounders. RESULTS A total of 344 MSM were recruited from March 19, 2019, to January 13, 2020, and 172 were randomized to the intervention group. At month 1 follow-up, there was no significant difference in the proportion of adherent participants between the intervention and control groups (66/144, 45.8% vs 57/134, 42.5%; P=.28). In the intervention group, 120 participants engaged in web-based communication with case managers and 158 accessed at least 1 of the delivered articles. The primary concern captured in the web-based conversation was the side effects of the medication (114/374, 30.5%), which was also one of the most popular educational articles topics. The majority (124/144, 86.1%) of participants that completed the month 1 survey rated the intervention as "very helpful" or "helpful." The number of educational articles accessed was associated with adequate adherence in the intervention group (odds ratio 1.08, 95% CI 1.02-1.15; P=.009). The intervention also improved the motivation score after adjusting for baseline values (β=2.34, 95% CI 0.77-3.91; P=.004). However, the number of web-based conversations, regardless of conversation features, was associated with lower motivation scores in the intervention group. CONCLUSIONS The intervention was well-received. Delivering educational resources of interest may enhance medication adherence. The uptake of the web-based communication component could serve as an indicator of real-life difficulties and could be used by case managers to identify potential inadequate adherence.

Abstract
BACKGROUND Medication nonadherence is an important public health issue that has individual and system-level implications. Nonadherence can lead to negative health outcomes and illness, which in turn produce increased healthcare costs for both the individual and system. The transtheoretical model of change (TTM) can be a useful basis for interventions, as it can identify patients' current stages of change and guide them from nonadherence to adherence. OBJECTIVE The objective of this systematic review was to determine the utilization of the TTM to predict or improve medication adherence in patients with chronic conditions. METHODS A systematic review of current literature was conducted to obtain an overview of the use of TTM-informed interventions for medication adherence in chronic conditions. PubMed, Embase, PsycInfo and CINAHL databases were searched in July 2020. The methodological quality of the studies was evaluated using the Downs and Black checklist. The Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines were followed for data extraction, analysis, and reporting. RESULTS Ten studies were included in the final data synthesis of this review. Eight of the reviewed studies supported the utility of TTM to predict or improve medication adherence in patients with chronic conditions, while two studies did not find any significant improvement in medication adherence after using a TTM-based intervention. The Downs and Black checklist revealed the overall methodological quality of the included studies to be fair [mean (SD) = 16.3 (4.5) of a possible maximum score of 28]. CONCLUSION This systematic review provides an overview of the utility of TTM in predicting and improving medication adherence in patients with chronic conditions. Although TTM-based interventions in patients with low or moderate medication adherence were effective, there were few studies identified, suggesting the need for further research.

Abstract
ISSUE ADDRESSED Australian pharmacists are increasingly moving towards the provision of patient-centred professional pharmacy services for chronic disease management. Some of these services are targeted towards improving patients' health and wellbeing through the facilitation of patient-driven health behaviour change. This paper investigates whether the provision of behaviour change interventions by Australian pharmacists is adequately underpinned by the current competency framework. METHODS The foundation and behaviour change competences within each of the domains in the generic health behaviour change competency framework (GHBC-CF), was mapped to the Australian pharmacist competency framework. RESULTS Although the Australian competency framework underpins most of the foundation and behaviour change competences of the GHB-CF required to undertake low-intensity interventions, for medium to high-intensity interventions four specific task-related competences need to be addressed. These are F12 'Ability to recognise barriers to and facilitators of implementing interventions', BC4 'ability to agree on goals for the intervention', BC5 'capacity to implement behaviour change models in a flexible but coherent manner' and BC6 'capacity to select and skilfully apply most appropriate intervention method'. CONCLUSION Additional training is necessary if pharmacists aspire to provide behaviour change interventions for chronic disease management, in particular those that are complex as they involve changes to multiple health behaviours. SO WHAT?: The identification of these gaps is critical and can potentially be addressed in postgraduate training programs and as pharmacy curricula are updated.

Abstract
Successful navigation of the HIV care continuum is necessary to maintain viral suppression. We explored gender-stratified correlates of being virally unsuppressed in the Prevention for Positives (P4P) component of HPTN 065. The outcome of interest was unsuppressed viral load (> 40 copies/mL) among individuals already living with HIV. Correlates included medication adherence factors, social support and stigma. Logistic regression models were stratified by gender (N = 673). Men-specific correlates of being virally unsuppressed included opposite-sex partners, older age and HIV disclosure stigma. Women-specific correlates included time since diagnosis, and personal-level barriers to medication adherence. When more individuals knew about their HIV status, women had over twice the likelihood of being virally unsuppressed; no such association was seen among men. Additionally, higher levels of social support were not associated with viral suppression among women. Interventions should consider gender-specific approaches to engaging social support in de-stigmatization of HIV and promotion of medication adherence and subsequent viral suppression.

Abstract
African-American men who have sex with men (MSM) with HIV are more likely to have unsuppressed viral load than other racial/ethnic groups. HPTN 065 Study, completed in 2015, consisted of five interconnected study components conducted at clinics in Bronx, New York and Washington, D.C. Participants completed surveys with questions related to socio-demographic factors and individual-level HIV medication adherence barriers, such as forgetting doses or fear of taking medications in front of others. Descriptive analyses and ordinal logistic regression with robust standard errors were conducted. Fifty-seven per cent of participants (N = 359) were African-American (57.1%) and roughly 40% had no more than a high school education. Mean age was 48 years. Overall, MSM with viral load suppression identified fewer individual-level barriers to adherence (p < .01) and individuals with depressive symptoms identified a greater number of barriers to adherence (p < .01). Compared to African-Americans, white MSM had a lower likelihood of identifying barriers to adherence (p < .05). Findings suggest that individual-level barriers to HIV medication adherence are common among MSM, irrespective of time since diagnosis and viral suppression. Race-specific interventions which address intersectional stigma are needed to improve health outcomes among African-American MSM, who bear much of the burden of poor HIV outcomes in the United States.

The use of discrete choice experiments in adherence research: A new solution to an old problem. Res Social Adm Pharm 2020; 16:1487-1492.

Abstract
Theory can play an important role in providing the framework, and underpinning the design and implementation of interventions to improve medication adherence. Interventions that are grounded in a theory are relatively more effective in improving medication adherence than interventions which do not have a theoretical support. However, a large body of adherence research does not appear to be linked to any theory or model, which therefore may have resulted in interventions that are either ineffective or not sustainable. Interventions that are based on theory have mainly employed socio-behavioural models to explain, and design interventions to address, the complex phenomenon of adherence. Yet, the effectiveness of these interventions is inconclusive, supporting the argument that socio-behavioural models alone have limited applicability in explaining behaviour associated with medication-taking. An important reason for this limitation may be the complex and dynamic nature of adherence. There is a need to include a wide variety of factors in a model and examine adherence in the context of its three phases (initiation, implementation, and discontinuation). One possible way forward is to also examine medication-taking behaviour from an economic perspective, for example, by using a discrete choice experiment (DCE), which provides a different approach to understanding human behaviour about medication-taking and the complexities of decision-making in adhering to medication. DCEs can help in understanding how patients decide to initiate, continue or discontinue taking medication, factors that influence their decision, and the relative importance of those factors, which can assist researchers to prioritise interventions to improve medication adherence. Integration of multiple theories is needed to examine adherence from multiple perspectives and design interventions that are effective and sustainable. This commentary focusses on the pros and cons of some of the commonly used socio-behavioural models in adherence research and suggests a way forward by incorporating DCEs in adherence research.

Abstract
BACKGROUND Qatar is currently experiencing a worrying increase in the prevalence of diabetes mellitus (DM). One of the most common reasons for uncontrolled DM is non-adherence to medications. The socio-behavioral intervention has proven effective in some chronic illnesses. OBJECTIVES To assess the stages of change (SOC) and medication adherence scores of type 2 diabetes mellitus (T2DM) patients visiting primary healthcare institutions in Qatar, and to evaluate the cause and effect relationship between SOC and adherence to antidiabetic medications. METHODS The 8-item Morisky Medication Adherence Scale (MMAS-8) was used to assess medication adherence, and a 2-item SOC questionnaire was utilized to classify the SOC. The analysis to determine if the SOC could predict medication adherence while controlling for demographic characteristics, total number of prescribed medications and disease duration was done using hierarchical multiple regression. RESULTS The final analysis included 387 patients. In relation to medication adherence, majority of the patients were in the maintenance stage (76.7%), followed by the preparation stage (14.7%), the action stage (3.9%), the contemplation stage (3.4%) and the precontemplation stage (1.3%). Most of the patients were in high adherence towards antidiabetic medications (50.3%) followed by low level (26.4%) and medium level (23.3%). SOC was significant and positively predicted medication adherence, which accounted for around 58 to 60% (p < 0.001) while controlling for covariates. CONCLUSIONS SOC was significant and positively predicted medication adherence. The study recommends that the SOC questionnaire could potentially be used to identify patients at risk for low adherence.

Abstract
Background: Transtheoretical model (TTM) is one of the most commonly used methods in behavioral change modeling. The aim of this study was to conduct a systematic review (SR) to determine research gaps with regard to this template with an emphasis on intervention for patients with chronic diseases (CDs). Materials and Methods: ISI-WOS, Scopus, PubMed, SID, and Magiran databases were examined systematically and on the basis of defined criteria. Titles, abstracts, and full texts of articles retrieved were examined for the presence of defined criteria. Then finalized articles were analyzed in consensus meetings. After that, references of selected articles and full text of those meeting the criteria were also analyzed. Results: We screened 103 articles, excluded 27 in abstract review and 34 in full-text review, leaving 42 articles for critical appraisal. Then the references of these 42 articles were also screened. Fifty articles were excluded on abstract review and 5 on full-text review, leaving 15 articles. The result of the analysis of 57 final articles of this SR determined that 28 articles were about aspects of TTM and 5 stages of change were the most commonly used aspect. Eight articles used TTM in intervention about CDs. A total of 21 articles examined TTM's pros and cons, most of which were about TTM's pros. Conclusions: The majority of studies focused on the effectiveness of TTM on the behavioral change management. This finding supported the hypothesis that TTM can be applied in the prevention of CDs.

Abstract
BACKGROUND People who inject drugs (PWID) constitute 60% of the approximately 5 million people in the U.S. infected with hepatitis C virus (HCV). Treatment of PWID is complex due to addiction, mental illness, poverty, homelessness, lack of positive social support, poor adherence-related skills, low motivation and knowledge, and poor access to and trust in the health care system. New direct-acting antiviral medications are available for HCV with high cure rates and few side effects. The life expectancy and economic benefits of new HCV treatments will not be realized unless we determine optimal models of care for the majority of HCV-infected patients. The purpose of this study is to evaluate the effectiveness of directly observed therapy and group treatment compared with self-administered individual treatment in a large, urban opioid agonist therapy clinic setting in the Bronx, New York. METHODS/DESIGN In this randomized controlled trial 150 PWID with chronic HCV were recruited from opioid agonist treatment (OAT) clinics and randomized to one of three models of onsite HCV treatment in OAT: 1) modified directly observed therapy; 2) group treatment; or 3) control - self-administered individual treatment. Participants were age 18 or older, HCV genotype 1, English or Spanish speaking, treatment naïve (or treatment experienced after 12/3/14), willing to receive HCV treatment onsite, receiving methadone or buprenorphine at the medication window at least once per week, and able to provide informed consent. Outcomes of interest include adherence (as measured by self-report and electronic blister packs), HCV treatment completion, sustained virologic response, drug resistance, and cost-effectiveness. DISCUSSION This paper describes the design and rationale of a randomized controlled trial comparing three models of care for HCV therapy delivered in an opioid agonist treatment program. Our trial will be critical to rigorously identify models of care that result in high adherence and cure rates. Use of blister pack technology will help us determine the role of adherence in successful cure of HCV. Moreover, the trial methodology outlined here can serve as a template for the development of future programs and studies among HCV-infected drug users receiving opioid agonist therapy, as well as the cost-effectiveness of such programs. TRIAL REGISTRATION This trial was registered with ClinicalTrials.gov ( NCT01857245 ). Trial registration was obtained prospectively on May 20th, 2013.

Abstract
The stages of change (SOC) theory suggests individuals adapt incrementally to behaviors like adherence, requiring different strategies over the behavior change continuum. Offering financial incentives (FIs) is one strategy to motivate adherence. This qualitative sub-study examined adherence barriers and the role of FIs to increase viral suppression (VS) among HIV Prevention Trials Network (HPTN) 065 study participants categorized into SOC-related adherence stages based on changes from baseline to follow-up viral load tests. Of 73 participants, most were in Maintenance stage (n = 31), defined as having achieved VS throughout HPTN 065, or in Action stage (n = 29), defined as moving from virally unsuppressed to suppressed in 50% or more of tests. Only 13 were Low Adherers, having achieved VS in fewer than 50% of tests. The latter group faced substantial social and structural adherence barriers. Participants in the Action stage made positive changes to adherence routines to achieve VS. Those in Maintenance were less incentivized by FIs, as they were already committed. Results from this sub-study suggest FI effectiveness may vary across the SOC continuum, with greatest impact for those initiating antiretroviral or without explicit adherence routines. FIs may be insufficient to overcome strong social or structural barriers, and unnecessary for those intrinsically committed to remaining adherent.

Abstract
OBJECTIVES The HIV care cascade provides milestones to track the progress of HIV-positive people from seroconversion through viral suppression. We propose a Motivational pre-exposure prophylaxis (PrEP) Cascade involving 5 stages based on the Transtheoretical Model of Change. METHODS We analyzed data from 995 men in One Thousand Strong, a longitudinal study of a national panel of HIV-negative gay and bisexual men in the United States. RESULTS Nearly all (89%) participants were sexually active in the past 3 months and 65% met Centers for Disease Control criteria for PrEP candidacy. Of those identified as appropriate candidates, 53% were Precontemplative (stage 1; unwilling to take or believing they were inappropriate candidates for PrEP) and 23% were in Contemplation (stage 2; willing and self-identified as appropriate candidates). Only 11% were in PrEParation (stage 3; seeing PrEP as accessible and planning to initiate PrEP) and 4% were in PrEP Action (stage 4; prescribed PrEP). Although few of those who were identified as appropriate candidates were on PrEP, nearly all PrEP users (98%) reported adhering to 4 or more doses per week and most (72%) were returning for recommended quarterly medical visits, resulting in 9% of PrEP candidates reaching Maintenance and Adherence (stage 5). CONCLUSIONS The large majority of participants were appropriate candidates for PrEP, yet fewer than 1 in 10 were using and adherent to PrEP. These findings highlight the need for interventions tailored to address the unique barriers men face at each stage of the cascade, particularly at the earliest stages where the most dramatic losses were identified.

Abstract
Few self-report measures of medication adherence have been rigorously developed and validated against electronic drug monitoring (EDM). Assess the validity of the 3-item self-report scale by comparing it with a contemporaneous EDM measure. We conducted an observational study in which adherence assessments were done monthly for up to 4 months for 81 patients with HIV who were taking antiretroviral medications. We report results for both HIV antiretroviral medications, and also for other, non-HIV-related medications. Raw and calibrated self-report adherence measures, electronic drug monitoring adherence measures, and sociodemographic variables. The mean age of patients was 46 years, 37 % were female, 49 % had some education beyond high school, 22 % were Black, and 22 % were Hispanic. Cronbach's alphas for the 3-item scale for HIV and non-HIV medications were 0.83 and 0.87, respectively. The mean differences (raw/uncalibrated self-report scale minus EDM) for HIV and non-HIV medications were 7.5 and 5.2 points on a 100-point scale (p < 0.05 for both). Pearson correlation coefficients between the calibrated 3-item scale and the EDM for HIV and non-HIV medications were 0.47 and 0.59, respectively. The c-statistics for the ROC curves for the calibrated scale, using cut-offs of 0.8 and 0.9 for the EDM gold standard measure to define non-adherence, were between 0.74 and 0.76 for HIV and non-HIV medications. This 3-item adherence self-report scale showed good psychometric characteristics and good construct validity when compared with an EDM standard, for both HIV and non-HIV medications. In clinical care it can be a useful first-stage screener for non-adherence. In clinical research and quality improvement settings it can be a useful tool when more complex and expensive methods such as EDM or pharmacy claims are impractical or unavailable.

Abstract
It has been shown that socioeconomic factors are associated with the prognosis of several chronic diseases; however, there is no recent systematic review of their effect on HIV treatment outcomes. We aimed to review the evidence regarding the existence of an association of socioeconomic status with virological and immunological response to antiretroviral therapy (ART). We systematically searched the current literature using the database PubMed. We identified and summarized original research studies in high-income countries that assessed the association between socioeconomic factors (education, employment, income/financial status, housing, health insurance, and neighbourhood-level socioeconomic factors) and virological response, immunological response, and ART nonadherence among people with HIV-prescribed ART. A total of 48 studies met the inclusion criteria (26 from the United States, six Canadian, 13 European, and one Australian), of which 14, six, and 35 analysed virological, immunological, and ART nonadherence outcomes, respectively. Ten (71%), four (67%), and 23 (66%) of these studies found a significant association between lower socioeconomic status and poorer response, and none found a significant association with improved response. Several studies showed that adjustment for nonadherence attenuated the association between socioeconomic status and ART response. Our review provides strong support that socioeconomic disadvantage is associated with poorer response to ART. However, most studies have been conducted in settings such as the United States without universal free healthcare access. Further study in settings with free access to ART could help assess the impact of socioeconomic status on ART outcomes and the mechanisms by which it operates.

Reasons for not starting antiretroviral therapy in HIV-1-infected individuals: a changing landscape. Infection 2016; 44:521-9.

Abstract
PURPOSE A cross-sectional survey was conducted to better understand why chronically HIV-1-infected individuals stratified by CD4 count (≤349; 350-499; ≥500 cells/μL) were not on antiretroviral therapy (ART). METHODS Before the consultation, treatment-naive patients and their physicians independently completed a 90-item-questionnaire about barriers and their readiness to start/defer ART. The study was carried out at 34 sites in nine countries in Europe and Australia. RESULTS Between December 2011 and October 2012, 508 pairs of patient- and physician-questionnaires were completed. 426 (84 %) patients were male and 39 (8 %), 138 (27 %), and 330 (65 %) were in the three stratified groups based on CD4 count, respectively. In the category 'Body and symptoms' the most commonly identified reason for patients not to start was: "As long as I feel good I don't have to take medication" (44 %). Less than 20 % of respondents indicated fears of side effects and toxicity or problems to manage pills. Most patients were in the lowest stage of treatment-readiness (N = 323, 68 %), especially patients with CD4 cells ≥500 cells/μL (N = 240, 79 %). Physicians answered in 92 (18 %) cases that ART was not indicated for CD4 cells <500 cells/μL. Main reasons for physicians not starting treatment for these patients were their perception that patients were 'too depressed' (13 %) or that they had not known them long enough (13 %). CONCLUSIONS Nowadays patient-barriers to ART are commonly related to health-and treatment-beliefs compared to fear of toxicity or ART manageability in the past. This new barrier pattern seems to reflect the era of well tolerated, easier ART regimens and has to be considered in light of the new recommendations to treat all HIV-infected individuals regardless of the CD4 cell count.

Abstract
Treatment as prevention is expected to have a major role in reducing HIV incidence, but other prevention interventions will also be required to bring the epidemic under control, particularly among key populations. One or more forms of pre-exposure prophylaxis (PrEP) will likely play a critical role. Oral PrEP with emtricitabine-tenofovir (Truvada®) is currently available in the US and some other countries, but uptake has been slow. We review the concerns that have contributed to this slow uptake and discuss current and future research in this critical area of HIV prevention research.

Abstract
Medication adherence is a major determinant of antiretroviral (ARV) treatment success and a significant challenge for HIV-positive patients, yet a well-defined adherence threshold to maintain virologic suppression on current ARV regimens remains unclear. The present study evaluated 1915 Kaiser Permanente Southern California HIV-positive patients on one of three regimen types: (1) emtricitabine-tenofovir-efavirenz (FTC-TDF-EFV); (2) emtricitabine-tenofovir (FTC-TDF) and raltegravir (RAL); and (3) FTC-TDF and a boosted protease inhibitor, either darunavir (DRV) or atazanavir (ATV), to compare virologic failure rates between patients with varying levels of adherence to the regimens. Medication possession ratios (MPRs) were calculated to determine adherence, and HIV RNA PCR levels drawn 12-18 months after the initial pharmacy claim for the measured drug were used to determine virologic failure, which was defined as two consecutive HIV RNA PCR measurements ≥200 copies/mL. Adherence was inversely related to virologic failure, with an 80-90% MPR threshold resulting in no more than 3.5% virologic failure rate. In comparison, ≥90% MPR yielded no more that 1.1% virologic failure rate. Although the gold-standard adherence threshold for older ARV regimens has been 95%, an 80-90% MPR appears sufficient to maintain virologic suppression in patients treated with these three ARV regimen types.

Abstract
We conducted a secondary data analysis of 11 AIDS Clinical Trials Group (ACTG) studies to examine longitudinal associations between 14 self-reported antiretroviral therapy (ART) adherence barriers (at 12 weeks) and plasma HIV RNA (at 24 weeks) and to discern the relative importance of these barriers in explaining virologic detectability. Studies enrolled from 1997 to 2003 and concluded between 2002 and 2012. We included 1496 (54.2% of the original sample) with complete data. The most commonly selected barriers were "away from home" (21.9%), "simply forgot" (19.6%), "change in daily routine" (19.5%), and "fell asleep/slept through dosing time" (18.9%). In bivariate analyses, "too many pills to take" (OR=0.43, p<0.001), "wanted to avoid side effects" (OR=0.54, p=0.001), "felt drug was toxic/harmful" (OR=0.44, p<0.001), "felt sick or ill" (OR=0.49, p<0.001), "felt depressed/overwhelmed" (OR=0.58, p=0.004), and "problem taking pills at specified time" (OR=0.71, p=0.04) were associated with a lower odds of an undetectable HIV RNA. "Too many pills to take," "wanted to avoid side effects," "felt drug was toxic/harmful," "felt sick/ill,", and "felt depressed/overwhelmed" had the highest relative importance in explaining virologic detectability. "Simply forgot" was not associated with HIV RNA (OR=0.99, p=0.95) and was ninth in its relative importance. Adherence interventions should prioritize barriers with highest importance in explaining virologic outcomes rather than focusing on more commonly reported barriers.

Abstract
[Purpose] The purpose of this study was to identify the distribution of stages of change in the exercise behavior of university students the transtheoretical model. [Subjects and Methods] Study subjects at four universities in G city were surveyed. A total of 1,000 questionnaires were distributed, and 959 responses were analyzed. The collected data was analyzed using descriptive statistics and multiple logistic regression analysis. [Results] Factors that contributed to the transition from the pre-contemplation stage to the contemplation stage included change-experimental processes (C-EP) and change-behavioral processes (C-BP). Factors that contributed to the transition from the contemplation stage to the preparation stage were C-BP and decisional decisional balance-cons (DB-C). Self-efficacy was the factor that contributed to the transition from the preparation stage to the action stage. However, there was no factor that contributed to the transition from the action stage to the maintenance stage. [Conclusion] When exercise behavior change is low, strategies such as giving one-to-one training, having the subjects read relevant books, and providing information are needed. When exercise behavior change is high, it is necessary to heighten self-efficacy by having subjects select and freely conduct appropriate kinds of exercises.

Abstract
Poor adherence to combination antiretroviral therapy (ART) is a major global challenge. In this study we examined the efficacy of a smartphone application incorporating personalized health-related visual imagery that provided real-time information about the level of medication and the patient's level of immunoprotection, in order to improve adherence to ART. We randomized 28 people on ART to either a standard or augmented version of the smartphone application. The augmented version contained components that illustrated participants' current estimated plasma concentrations of antiretroviral drugs and the immune protection provided by ART. Adherence to ART was assessed at baseline and at 3 months using self-reported adherence, pharmacy dispensing records, and HIV viral load. Information was also collected on illness and medication beliefs and use of the application. Participants who received the augmented application showed a significantly higher level of self-reported adherence to ART at 3 months (p=0.03) and decreased viral load (p=0.023) as compared to individuals using the standard version. Greater usage of the extra components of the augmented application was associated with greater perceived understanding of HIV infection and increased perceived necessity for ART. Smartphone applications that incorporate personalized health-related visual imagery may have potential to improve adherence to ART.

Abstract
Young, Black men who have sex with men and transgender women who have sex with men (YBMSM/TW) are at disproportionate risk for HIV and other sexually transmitted infections (HIV/STI). HealthMpowerment.org (HMP) is a mobile phone optimised online intervention that utilises behaviour change and gaming theories to reduce risky sexual behaviours and build community among HIV-positive and negative YBMSM/TW. The intervention is user-driven, provides social support, and utilises a point reward system. A four-week pilot trial was conducted with a diverse group of 15 YBMSM/TW. During exit interviews, participants described how HMP components led to behaviour changes such as asking partners' sexual history, increased condom use, and HIV/STI testing. The user-driven structure, interactivity, and rewards appeared to facilitate sustained user engagement and the mobile platform provided relevant information in real-time. Participants described the reward elements of exceeding their previous scores and earning points toward prizes as highly motivating. HMP showed promise for being able to deliver a sufficient intervention dose and we found a trend toward higher dose received and more advanced stages of behaviour change. In this pilot trial, HMP was well accepted and demonstrates promise for translating virtual intervention engagement into actual behaviour change to reduce HIV risk behaviours.
