Disclosure of one's HIV status can help to improve uptake and retention in prevention of mother-to-child transmission of HIV services; yet, it remains a challenge for many women. This systematic review evaluates disclosure rates among pregnant and postpartum women in sub-Saharan Africa, timing of disclosure, and factors affecting decisions to disclose. PubMed and EMBASE databases were searched to identify relevant studies published between January 2000 and April 2014. Rates of HIV serostatus disclosure to any person ranged from 5.0% to 96.7% (pooled estimate: 67.0%, 95% CI: 55.7%-78.3%). Women who chose to disclose their status did so more often to their partners (pooled estimate: 63.9%; 95% CI: 56.7%-71.1%) than to family members (pooled estimate: 40.1; 95% CI: 26.2%-54.0%), friends (pooled estimate: 6.4%; 95% CI: 3.0%-9.8%), or religious leaders (pooled estimate: 7.1%; 95% CI: 4.3%-9.8%). Most women disclosed prior to delivery. Decisions to disclose were associated with factors related to the woman herself (younger age, first pregnancies, knowing someone with HIV, lower levels of internalized stigma, and lower levels of avoidant coping), the partner (prior history of HIV testing and higher levels of educational attainment), their partnership (no history of domestic violence and financial independence), and the household (higher quality of housing and residing without co-spouses or extended family members). Interventions to encourage and support women in safely disclosing their status are needed.

Epidemiologic studies have shown inconsistent conclusions about the effect of caffeine intake during pregnancy on the risk of low birth weight (LBW). We performed a meta-analysis and linear-dose response analysis examining the association between caffeine consumption during pregnancy and risk of LBW. PubMed and EMBASE were searched for relevant articles published up to March 2014. Eight cohort and four case-control studies met all inclusion criteria. Using a random-effects model of the twelve studies, the pooled odds ratio (OR) for the risk of LBW comparing the highest versus lowest level of caffeine intake during pregnancy was 1.38 (95% CI: 1.10, 1.73). Linear dose-response analysis showed that every additional 100 mg of caffeine intake (1 cup of coffee or 2 cups of tea) per day during pregnancy was associated with a 3.0% increase in OR for LBW. There was a moderate level of overall heterogeneity with an I-squared value of 55% (95% CI: 13, 76%), and no evidence of publication bias based on Egger’s test (P = 0.20) and the funnel plot. Thus, high caffeine intake during pregnancy is associated with a significant increase in the risk of LBW, and this risk appears to increase linearly as caffeine intake increases.

BackgroundWireless electronic adherence monitors can detect antiretroviral therapy (ART) adherence lapses and trigger interventions in real time, thus potentially avoiding unnecessary HIV viremia. Evidence about the acceptability and feasibility of these monitors and associated interventions, however, is limited.ObjectiveThe aim of this study was to assess the acceptability and feasibility of real-time adherence monitoring linked to text messaging (short message service, SMS) reminders and notifications to support adherence among individuals living with HIV who are taking ART in rural southwestern Uganda.MethodsIndividuals living with HIV who were initiating ART were enrolled in a pilot randomized controlled trial and followed up for 9 months. Participants received a real-time adherence monitor and were randomized to one of the following study arms: (1) scheduled SMS, (2) SMS triggered by missed or delayed doses, or (3) no SMS. SMS notifications were also sent to 45 patient-identified social supporters for sustained adherence lapses in the scheduled SMS and triggered SMS arms. Study participants and social supporters participated in qualitative semistructured in-depth interviews on acceptability and feasibility of this technology. An inductive, content analytic approach, framed by the unified theory of acceptance and use of technology model, was used to analyze qualitative data. Quantitative feasibility data, including device functionality and SMS tracking data, were recorded based upon device metrics collected electronically and summarized descriptively.ResultsA total of 63 participants participated in the study. Participants reported that real-time monitoring intervention linked to SMS reminders and notifications are generally acceptable; the predominant feedback was perceived utility—the intervention was beneficial in motivating and reminding patients to take medication, as well as enabling provision of social support.The intervention was found to be technically feasible, as data were obtained from most participants as expected most of the time. Potential challenges included the impact of the technology on confidentiality, shared phone ownership, usability skills, and availability of electricity.ConclusionsReal-time adherence monitoring integrated with SMS reminders and social support notifications is a generally acceptable (based primarily on perceived utility) and feasible intervention in a resource-limited country. Future efforts should focus on optimized device design, user training to overcome the challenges we encountered, cost effectiveness studies, as well as studying the monitoring aspect of the device without accompanying interventions.Trial RegistrationClinicalTrials.gov NCT01957865; https://clinicaltrials.gov/ct2/show/NCT01957865 (Archived by WebCite at http://www.webcitation.org/6zFiDlXDa)

Objective:To understand how a pilot intervention combining SMS reminders with real-time adherence monitoring improved adherence to HIV antiretroviral therapy (ART) for adults initiating treatment in rural Uganda.Design:Qualitative study, conducted with a pilot randomized controlled trial.Methods:Sixty-two pilot intervention study participants took part in qualitative interviews on: preferences for content; frequency and timing of SMS adherence reminders; understandings and experiences of SMS reminders; and understandings and experiences of real-time adherence monitoring. Analysis of interview data was inductive and derived categories describing how participants experienced the intervention, and what it meant to them.Results:SMS reminders prompted taking individual doses of antiretroviral therapy, and helped to develop a ‘habit’ of adherence. Real-time adherence monitoring was experienced as ‘being seen’; participants interpreted ‘being seen’ as an opportunity to demonstrate seriousness of commitment to treatment and ‘taking responsibility’ for adherence. Both SMS reminders and real-time monitoring were interpreted as signs of ‘caring’ by the healthcare system. Feeling ‘cared about’ offset depressed mood and invigorated adherence.Conclusion:Although serving as reminders, SMS messages and real-time adherence monitoring also had larger emotional and moral meanings for participants that they felt improved their adherence. Understanding the larger ‘meanings in the messages,’ as well as their more literal content and function, will be central in delineating how SMS reminders and other adherence interventions using cellular technology work or do not work in varying contexts.

In 2012, there were an estimated 2 million children in need of antiretroviral therapy (ART) in the world, but ART is still reaching fewer than 3 in 10 children in need of treatment. [1, 7] As more HIV-infected children are identied early and universal treatment is initiated in children under 5 regardless of CD4, the success of pediatric HIV programs will depend on our ability to link children into care and treatment programs, and retain them in those services over time. In this review, we summarize key individual, institutional, and systems barriers to diagnosing children with HIV, linking them to care and treatment, and reducing loss to follow-up (LTFU). We also explore how linkage and retention can be optimally measured so as to maximize the impact of available pediatric HIV care and treatment services.
