We used data from the STD Surveillance Network to estimate HIV testing among patients being tested or treated for gonorrhea. Of 1,845 gonorrhea-infected patients identified through nationally notifiable disease data, only 51% were tested for HIV when they were tested or treated for gonorrhea. Among the 10 geographic sites in this analysis, the percentage of patients tested for HIV ranged from 22–63% for men and 20–79% for women. Nearly 33% of the un-tested patients had never been previously HIV-tested. STD clinic patients were more likely to be HIV-tested than those in other practice settings.

It is not well understood how infection with HIV and prior experience of sexual violence affects sexual behavior in African women. We describe factors influencing current sexual practices of Rwandan women living with or without HIV/AIDS. By design, 75 % of participants were HIV positive and ~50 % reported having experienced genocidal rape. Univariate and multivariate logistic regression models were fit to describe demographic and clinical characteristics that influenced sexual behavior in the previous 6 months, condom use, history of transactional sex, and prior infection with a non-HIV sexually transmitted disease. Respondents’ age, where they lived, whether or not they lived with a husband or partner, experience of sexual trauma, CD4 count, CES-D and PTSD scores were strongly associated with risky sexual behavior and infection with non-HIV STI. HIV positive women with a history of sexual violence in the contexts of war and conflict may be susceptible to some high-risk sexual behaviors.

Depression is a known barrier for antiretroviral therapy (ART) adherence, but less is understood about its effects on ART initiation. We followed 1013 HIV-infected individuals participating in the Partners Demonstration Project, an open-label study of integrated pre-exposure prophylaxis (PrEP) and ART delivery for HIV serodiscordant couples in Kenya and Uganda. Associations between depression, measured annually with the Hopkins Symptoms Checklist-Depression (HSCL-D), and ART initiation were assessed with Cox proportional hazards regression. At enrollment, 162 participants (16.0%) reported symptoms consistent with probable depression, defined by a HSCL-D mean score >1.75, and this proportion decreased during study follow-up (6.7 and 3.6% at 12- and 24-months, respectively; p value < 0.001). Greater depressive symptom severity was associated with a greater likelihood of ART initiation overall (adjusted hazard ratio [aHR] 1.32, 95% CI 1.01–1.73) and among participants with CD4 count ≤ 350 cells/µl (aHR 1.30, 95% CI 1.01–1.67). Depression decreased 6 months after ART initiation (adjusted odds ratio [aOR] 0.34, 95% CI 0.23–0.51). Among East African HIV-infected persons in HIV serodiscordant couples, depression was not a barrier to ART initiation. ART initiation was associated with improved depressive symptoms in this setting.

A qualitative assessment of Kenyan men who have sex with men taking daily and intermittent oral HIV pre-exposure prophylaxis (PrEP) found stigma, sex work, mobility, and alcohol impacted adherence. We analyzed quantitative data from the same cohort to explore different definitions of intermittent adherence. Volunteers were randomized to daily emtricitabine/tenofovir or placebo, or intermittent (prescription: Mondays/Fridays/after sex, maximum 1 dose/day) emtricitabine/tenofovir or placebo (2:1:2:1), and followed for 4 months. By electronic monitoring, median adherence for daily dosing was 80 %. Median adherence for intermittent dosing was 71 % per a “relaxed” definition (accounting for off-prescription dosing) and 40 % per a “strict” definition (limited to the prescription). Factors associated with lower adherence included travel, transactional sex, and longer follow-up; higher adherence was associated with daily dosing and an income. The definition of intermittent dosing strongly affects interpretation of adherence. These findings suggest interventions should address challenges of mobility, sex work, and long-term PrEP.

Problematic substance use may attenuate the effect of treating depression in people living with HIV (PLWH). We examined the potential moderating effect of problematic substance use on depression and adherence outcomes in PLWH (N = 143) who participated in a randomized controlled trial of cognitive behavioral therapy for adherence and depression (CBT-AD) and were randomized to either CBT-AD or enhanced treatment as usual (ETAU). Problematic substance use was operationalized as either having substance use-related diagnosis or current substance use in the past 30 days with a lifetime history of problematic use. Acute (baseline to 4-month) and follow up (4, 8, and 12-month) general linear modeling with time, condition, problematic baseline substance use, and corresponding interactions demonstrated that substance use did not significantly moderate the effects of CBT-AD on adherence or depression improvements. Therefore, CBT-AD was beneficial for PLWH with depression, regardless of problematic substance use when starting depression treatment. Based on these results, clinicians should not withhold CBT treatment for depression in patients with HIV and problematic substance use to attain reductions in depression and gains in adherence.

Short message service (SMS) surveys are a promising data collection method and were used to measure sexual behavior and adherence to HIV pre-exposure prophylaxis (PrEP) among HIV-uninfected partners of serodiscordant couples enrolled in a sub-study of the Partners Demonstration Project (an open-label study of integrated antiretroviral therapy and PrEP for HIV prevention in Kenya and Uganda). Questionnaires were completed by 142 participants after study exit. Median age was 29 years; 69% were male. Ninety-five percent (95%) felt SMS surveys were “easy” or “very easy”, 74% reported no challenges, and 72% preferred SMS surveys over in-person study visits. Qualitative interviews involving 32 participants confirmed the ease of responding to SMS surveys. Participants also indicated that surveys acted as reminders for adherence to PrEP and condom use and were experienced as support from the study. SMS surveys were generally found to be acceptable in this population and provided real-time context of PrEP use.

Although mobile health (mHealth) technologies have shown promise in improving clinical care in resource-limited settings (RLS), they are infrequently brought to scale. One limitation to the success of many mHealth interventions is inattention to end-user acceptability, which is an important predictor of technology adoption. We conducted in-depth interviews with 43 people living with HIV in rural Uganda who had participated in a clinical trial of a short messaging system (SMS)-based intervention designed to prompt return to clinic after an abnormal laboratory test. Interviews focused on established features of technology acceptance models, including perceived ease of use and perceived usefulness, and included open-ended questions to gain insight into unexplored issues related to the intervention’s acceptability. We used conventional (inductive) and direct content analysis to derive categories describing use behaviors and acceptability. Interviews guided development of a proposed conceptual framework, the technology acceptance model for resource-limited settings (TAM-RLS). This framework incorporates both classic technology acceptance model categories as well as novel factors affecting use in this setting. Participants described how SMS message language, phone characteristics, and experience with similar technologies contributed to the system’s ease of use. Perceived usefulness was shaped by the perception that the system led to augmented HIV care services and improved access to social support from family and colleagues. Emergent themes specifically related to mHealth acceptance among PLWH in Uganda included (1) the importance of confidentiality, disclosure, and stigma, and (2) the barriers and facilitators downstream from the intervention that impacted achievement of the system’s target outcome. The TAM-RLS is a proposed model of mHealth technology acceptance based upon end-user experiences in rural Uganda. Although the proposed model requires validation, the TAM-RLS may serve as a useful tool to guide design and implementation of mHealth interventions.

Our objective was to investigate antiretroviral adherence device use by HIV-infected youth and assess associations of device use with viral suppression and self-reported adherence. This cross-sectional, multisite, clinic-based study included data from 1,317 HIV-infected individuals 12–24 years of age that were prescribed antiretroviral therapy. Mean adherence in the past 7 days was 86.1 % and 50.5 % had an undetectable HIV RNA. Pillbox was the most commonly endorsed device. No specific device was independently associated with higher odds of 100 % adherence. Paradoxically, having an undetectable HIV RNA was inversely associated with use of adherence devices (OR 0.80; p = 0.04); however, among those with <100 % adherence, higher adherence was associated with use of one or more adherence devices (coefficient = 7.32; p = 0.003). Our data suggest that adolescents who experienced virologic failure often used adherence devices which may not have been sufficiently effective in optimizing adherence. Therefore, other tailored adherence-enhancing methods need to be considered to maximize virologic suppression and decrease drug resistance and HIV transmission.

Poverty alleviation programs can reduce HIV incidence but may have greater impacts when combined with other psychosocial interventions. We modeled the change in HIV incidence among South African adolescent girls and young women (AGYW) associated with combining a cash transfer (the South African Child Support Grant (CSG)) with other structural and behavioral interventions. We modeled observational data from the HPTN 068 study where 2328 HIV negative AGYW (13–20 years) were followed for 4 years. In a Monte Carlo simulation based on this cohort (N = 10,000), CSG receipt was not independently associated with HIV incidence. Providing the CSG combined with increasing caregiver care and reducing adolescent depression had the largest reduction in HIV incidence with the fewest number of combined interventions (RD − 3.0%; (95% CI − 5.1%, − 0.9%). Combining a monthly grant with interventions to increase caregiver care and reduce adolescent depression could substantially reduce HIV incidence above the provision of cash alone.
