Evaluation of differentiated service delivery models on HIV treatment retention among key populations in Nigeria
Linkage to treatment was suboptimal across both models with less than 90% of newly-diagnosed positives initiated on treatment and suggests that facilitated linkage is required to achieve at least 95%. Though retention was higher in the OSS model, both models had an alarmingly short time frame for LTFU and thus intensive monitoring during this phase of treatment is recommended irrespective of the type of DSD. Addressing these gaps will improve ser…
How to do (or not to do)… health resource allocations using constrained mathematical optimization
Despite the push towards evidence-based health policy, decisions about how to allocate health resources are all too often made on the basis of political forces or a continuation of the status quo. This results in wastage in health systems and loss of potential population health. However, if health systems are to serve people best, then they must operate efficiently and equitably, and appropriate valuation methods are needed to determine how to do…
Quality of Care is Perceived to be High with Community-based Antiretroviral Therapy (ART) Services for Female Sex Workers in Tanzania
This qualitative study reports on female sex workers' (FSWs) perceptions of the quality of antiretroviral therapy (ART) services they received as part of a community-based ART distribution intervention compared to services received by FSWs in the standard of care (SOC) arm. In-depth interviews were conducted with 24 participants to explore their perceptions of the quality of ART services. Data was analyzed using a quality-of-care framework that i…
Impacts of Covid-19-related service disruptions on TB incidence and deaths in Indonesia, Kyrgyzstan, Malawi, Mozambique, and Peru
Initial global-level estimates reported in June 2020 by the World Health Organization suggested that levels of disruption to TB service delivery could be as high as 25%-50% and result in an additional 6·3 million cases of tuberculosis (TB) and an additional 1·4 million TB-related deaths attributable to COVID-19 between 2020 and 2025. Quarterly epidemiological estimates and programmatic TB data capturing disruption levels to each TB service were c…
Operationalizing the distribution of oral HIV self-testing kits to men who have sex with men (MSM) in a highly homophobic environment
This study showed the practical steps involved in operationalizing KOL support system distribution of HIVST that positively influenced the testing experience for the participants irrespective of the HIV status and engagement in care. KOLs are a reliable resource to leverage for ensuring that HIV self-test kit is utilized and HIV positive individuals are linked to treatment and care in homophobic environments
Cost-Effectiveness of Peer-Delivered HIV Self-Tests for MSM in Uganda
Introduction: Distribution of HIV self-testing (HIVST) kits through MSM peer networks is a novel and effective strategy to increase HIV testing coverage in this high-risk population. No study has evaluated the cost or cost effectiveness of peer distribution of HIVST strategies among MSM in sub-Saharan Africa. Methods: From June to August 2018, we conducted a pilot study of secondary MSM peer HIVST kit distribution at The AIDS Support Organization…
Community-based antiretroviral therapy (ART) delivery for female sex workers in Tanzania
To increase linkage to and retention in antiretroviral therapy (ART) care, we piloted a community-based, ART service delivery intervention for female sex workers (FSWs). At baseline, we recruited and collected data from 617 FSWs (intervention: 309; comparison: 308) who were HIV positive and not on ART. This paper presents (1) the description of the intervention model, and (2) key descriptive and bivariate-level findings of the baseline FSW cohort…
Community-Based Antiretroviral Therapy (ART) Delivery for Female Sex Workers in Tanzania
We conducted an implementation science study of a community-based ART distribution program for HIV-positive female sex workers (FSW) whereby clients received ART services through community-based mobile and home-based platforms. We compared 6-month treatment-related outcomes in the community-based ART arm (N = 256) to the standard facility-based ART delivery arm (N = 253). Those in the intervention arm were more likely to have initiated ART (100.0…
High Burden of HIV, Syphilis and HSV-2 and Factors Associated with HIV Infection Among Female Sex Workers in Tanzania
Randomized evaluation and cost-effectiveness of HIV and sexual and reproductive health service referral and linkage models in Zambia
ISRCTN84228514 Retrospectively registered. The study was retrospectively registered in the ISRCTN clinical trials registry on 06 October 2015. The first recruitment of participants occurred on 17 December 2013
High levels of bisexual behavior and factors associated with bisexual behavior among men having sex with men (MSM) in Nigeria
Nigerian men who have sex with men (MSM) have a high burden of HIV infection and are known to engage in bisexual behavior. This study presents the first data on characteristics and correlates of Nigerian men having sex with men and women (MSMW) in three Nigerian cities. Five hundred and fifty-seven MSM who engaged in anal sex with men completed a behavioral survey; 48.1% of these MSM also engaged in sex with women in the previous 2 months. MSMW d…
Effectiveness of a combination prevention strategy for HIV risk reduction with men who have sex with men in Central America
PASMO's strategies to reach MSM with HIV prevention programming are still achieving low levels of population coverage, and few men are receiving the complete essential package. However, those reached are able to practice HIV prevention. Combination prevention is a promising approach in Central America, requiring expansion in coverage and intensity
Effectiveness of Behavior Change Communications for Reducing Transmission Risks Among People Living with HIV in 6 Countries in Central America
This first region-wide study (N = 2,818) aims to estimate prevalence of HIV-related risks (sexual behavior, HIV disclosure, number of sex partners, violence) and factors associated with these risks as well as evaluate a behavior change communications program targeted to PLHIV in 6 countries in Central America. After 2 years, the program achieved moderate coverage, with 21 % of the sample reporting exposure to interpersonal communications (IPC) an…
Comparing Estimates of Multiple and Concurrent Partnerships Across Population Based Surveys
HIV-related conspiracy beliefs and its relationships with HIV testing and unprotected sex among men who have sex with men in Tshwane (Pretoria), South Africa
The objective of this study was to determine extent of HIV conspiracy belief endorsement among men who have sex with men (MSM) in Pretoria, and assess whether endorsement of HIV conspiracy beliefs are associated with inconsistent condom use and never testing for HIV. A cross-sectional survey using respondent-driven sampling was conducted between February and August 2009. A high proportion of respondents endorsed HIV conspiracy beliefs. MSM common…
Attitudinal and Behavioral Factors Associated with Extramarital Sex Among Nigerian Men
Using couple data from a national survey, this article examines couple's characteristics associated with extramarital sex among Nigerian men. We found 15.4% of married men had extramarital sex in the past 12 months. Extramarital sex was significantly associated with men's attitude toward extramarital sex (OR = 1.7 [1.4–3.0]), early sexual debut (OR = 1.9 [1.6–2.3]), alcohol use (OR = 1.7 [1.4–2.1]), and intimate partner violence against wife (IPV…
Physical and Mental Health Consequences of Katrina on Vietnamese Immigrants in New Orleans
Levels and Correlates of Internalized Homophobia Among Men Who Have Sex with Men in Pretoria, South Africa
Disclosure of HIV Status to Sex Partners Among HIV-Infected Men and Women in Cape Town, South Africa
Evacuation and Return of Vietnamese New Orleanians Affected by Hurricane Katrina
Hurricane Katrina struck New Orleans East—where the main Vietnamese enclave is located— especially hard. By chance, shortly before this disaster, sociodemographic and health data had been collected for a population-based sample of working-age Vietnamese Americans living in New Orleans. One year after the storm, the authors reinterviewed nearly all respondents from the original sample who had returned to the area, which netted about two thirds of …
