Programme science: a route to effective coverage and population-level impact for HIV and sexually transmitted infection prevention. Lancet HIV 2023; 10:e825-e834. [PMID: 37944547 DOI: 10.1016/s2352-3018(23)00224-2] [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: 04/03/2023] [Revised: 08/10/2023] [Accepted: 08/22/2023] [Indexed: 11/12/2023]
Abstract
Improvements in context-specific programming are essential to address HIV and other sexually transmitted and blood-borne infection epidemics globally. A programme science approach emphasises the need for context-specific evidence and knowledge, generated on an ongoing basis, to inform timely and appropriate programmatic decisions. We aim to accelerate and improve the use of embedded research, inquiry, and learning to optimise population-level impact of public health programmes and to introduce an effective programme coverage framework as one tool to facilitate this goal. The framework was developed in partnership with public health experts in HIV and sexually transmitted and blood-borne infections through several workshops and meetings. The framework is a practice-based tool that centres on the use of data from iterative cycles of programme-embedded research and learning, as well as routine programme monitoring, to refine the strategy and implementation of a programme. This programme science approach aims to reduce programme coverage gaps, to optimise impact at the population level, and to achieve effective coverage. This framework should facilitate the generation of programme-embedded research and learning agendas to inform resource allocation, optimise population-level impact, and achieve equitable and effective programme coverage.

Effectiveness of Cash Transfer Delivered Along With Combination HIV Prevention Interventions in Reducing the Risky Sexual Behavior of Adolescent Girls and Young Women in Tanzania: Cluster Randomized Controlled Trial. JMIR Public Health Surveill 2022; 8:e30372. [PMID: 36121686 PMCID: PMC9531008 DOI: 10.2196/30372] [Citation(s) in RCA: 2] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/12/2021] [Revised: 05/19/2022] [Accepted: 08/02/2022] [Indexed: 01/21/2023] Open
Abstract
BACKGROUND Poverty and social inequality exacerbate HIV risk among adolescent girls and young women (AGYW) in sub-Saharan Africa. Cash transfers can influence the structural determinants of health, thereby reducing HIV risk. OBJECTIVE This study assessed the effectiveness of cash transfer delivered along with combination HIV prevention (CHP) interventions in reducing the risky sexual behavior of AGYW in Tanzania. The incidence of herpes simplex virus type 2 (HSV-2) infection was used as a proxy for sexual risk behavior. METHODS A cluster randomized controlled trial was conducted in 15 matched pairs of communities (1:1 intervention to control) across 3 strata (urban, rural high-risk, and rural low-risk populations) of the Shinyanga Region, Tanzania. The target population was out-of-school AGYW aged 15-23 years who had completed 10-hour sessions of social and behavior change communication. Eligible communities were randomly assigned to receive CHP along with cash transfer quarterly (intervention group) or solely CHP interventions (control group) with no masking. Study recruitment and baseline survey were conducted between October 30, 2017 and December 1, 2017. Participants completed an audio computer-assisted self-interview, HIV counselling and testing, and HSV-2 testing at baseline and during follow-up visits at 6, 12, and 18 months after the baseline survey. A Cox proportional hazards model with random effects specified at the level of clusters (shared frailty) adjusted for matching pairs and other baseline imbalances was fitted to assess the effects of cash transfer on the incidence of HSV-2 infection (primary outcome). Secondary outcomes included HIV prevalence at follow-up, self-reported intergenerational sex, and self-reported compensated sex. All secondary outcomes were measured at each study visit. RESULTS Of the 3026 AGYW enrolled in the trial (1482 in the intervention and 1544 in the control), 2720 AGYW (1373 in the intervention and 1347 in the control) were included in the final analysis. Overall, HSV-2 incidence was not significantly different at all follow-up points between the study arms in the adjusted analysis (hazard ratio 0.96, 95% CI 0.67-1.38; P=.83). However, HSV-2 incidence was significantly lower in the rural low-risk populations who received the cash transfer intervention (hazard ratio 0.45, 95% CI 0.29-0.71; P=.001), adjusted for potential confounders. CONCLUSIONS Although this trial showed no significant impact of the cash transfer intervention on HSV-2 incidence among AGYW overall, the intervention significantly reduced HSV-2 incidence among AGYW in rural low-risk communities. Factors such as lesser poverty and more asset ownership in urban and rural high-risk communities may have undermined the impact of cash transfer.

The magnitude of hypertension and associated factors among clients on highly active antiretroviral treatment in Southern Ethiopia, 2020: A hospital-based cross-sectional study. PLoS One 2021; 16:e0258576. [PMID: 34653207 PMCID: PMC8519467 DOI: 10.1371/journal.pone.0258576] [Citation(s) in RCA: 7] [Impact Index Per Article: 2.3] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/07/2020] [Accepted: 09/21/2021] [Indexed: 11/19/2022] Open
Abstract
INTRODUCTION Following the introduction of Highly Active Anti Retro Viral Treatment (HAART), the survival of people living with HIV/AIDS (PLHIV) has improved. However, hypertension remains a major challenge for people living with HIV. Very little effort has been made to examine the magnitude of hypertension and its contributing factors among clients receiving HAART, particularly in southern Ethiopia. Hence, the current study aimed at determining the frequency of Hypertension and associated factors among clients receiving HAART at Wachemo University Nigist Eleni Mohammed Memorial Referral Hospital, southern Ethiopia, 2020. METHODS A hospital-based cross-sectional study took place from January 20- March 20, 2020. A systematic sampling technique was employed in the selection of 397 clients. Interviewer administered pretested structured questionnaire was used for data collection. Blood pressure and anthropometric parameters of PLHIV were measured. The data was encoded and entered using Epi Data Version 3.1 and exported to SPSS version 23 for analysis. Then bivariable and multivariable logistic regression analyses were used to identify associated factors. Adjusted Odds Ratio (AOR) with 95% CI was used to present the estimated effect size and declare the presence of statistically significant association respectively. RESULTS The magnitude of hypertension among clients on HAART was 11.0% 95% CI [7.93, 14.04]. Being on HAART for at least 60 months (AOR: 2.57, 95% CI: 1.24-5.21), being on TDF/3TC/EFV combination (AOR: 4.61, 95% CI: 2.52-8.3), and high alcohol consumption (AOR: 4.31, 95% CI: 1.84-10.02) were identified as significant predictors of hypertension among clients on HAART. CONCLUSION AND RECOMMENDATION The magnitude of hypertension in the study area was in a considerable state to plan and implement intervention measures. For those clients who have received TDF/3TC/EFV and TDF/3TC/NVP and those who have been on HAART for 60 months, a strong emphasis should be placed on planning a strict follow-up. A concerted effort among health care providers is needed through counseling and education to discourage the habit of high alcohol consumption among clients.

Abstract
HIV-related stigma has been associated with worse health-related quality of life (HRQoL) among people living with HIV (PLWH). Little is known about how different types of HIV-related stigma (i.e., anticipatory, internalized, or enacted HIV-related stigma) influence HRQoL and whether these relationships differ by gender. The sample included 912 PLWH aged 18 years or older enrolling in HIV care at four health facilities in Tanzania. HRQoL was assessed with the life satisfaction and overall function subscales of the HIV/AIDS-Targeted Quality of Life (HAT-QoL) instrument. Sex-stratified multivariable logistic regression modeled the association of anticipatory, internalized, and enacted HIV-related stigma on poor HRQoL. Across all participants, the mean life satisfaction score was 63.4 (IQR: 43.8, 81.3) and the mean overall function score was 72.0 (IQR: 58.3, 91.7). Mean HRQoL scores were significantly higher for women compared to men for overall function (5.1 points higher) and life satisfaction (4.3 points higher). Fourteen percent of respondents reported recent enacted HIV-related stigma and 13% reported recent medium or high levels of internalized stigma. In multivariable models, high internalized and high anticipatory stigma were significantly associated with higher odds of poor life satisfaction and poor overall function in both men and women. Psychosocial interventions to prevent or reduce the impact of internalized and anticipatory stigma may improve HRQoL among persons in HIV care. Future research should longitudinally examine mechanisms between HIV-related stigma, poor HRQoL, and HIV care outcomes.

Abstract
BACKGROUND The data needed to understand the characteristics and outcomes, over time, of adolescents enrolling in HIV care in East Africa are limited. SETTING Six HIV care programs in Kenya, Tanzania, and Uganda. METHODS This retrospective cohort study included individuals enrolling in HIV care as younger adolescents (10-14 years) and older adolescents (15-19 years) from 2001-2014. Descriptive statistics were used to compare groups at enrollment and antiretroviral therapy (ART) initiation over time. The proportion of adolescents was compared with the total number of individuals aged 10 years and older enrolling over time. Competing-risk analysis was used to estimate 12-month attrition after enrollment/pre-ART initiation; post-ART attrition was estimated by Kaplan-Meier method. RESULTS A total of 6344 adolescents enrolled between 2001 and 2014. The proportion of adolescents enrolling among all individuals increased from 2.5% (2001-2004) to 3.9% (2013-2014, P < 0.0001). At enrollment, median CD4 counts in 2001-2004 compared with 2013-2014 increased for younger (188 vs. 379 cells/mm, P < 0.0001) and older (225 vs. 427 cells/mm, P < 0.0001) adolescents. At ART initiation, CD4 counts increased for younger (140 vs. 233 cells/mm, P < 0.0001) and older (64 vs. 323 cells/mm, P < 0.0001) adolescents. Twelve-month attrition also increased for all adolescents both after enrollment/pre-ART initiation (4.7% vs. 12.0%, P < 0.001) and post-ART initiation (18.7% vs. 31.2%, P < 0.001). CONCLUSIONS Expanding HIV services and ART coverage was likely associated with earlier adolescent enrollment and ART initiation but also with higher attrition rates before and after ART initiation. Interventions are needed to promote retention in care among adolescents.

Abstract
BACKGROUND Although non-occupational Human Immunodeficiency Virus (HIV) post-exposure prophylaxis (nPEP) has been proven to be efficacious in preventing HIV, it remains an underutilized prevention strategy in Nigeria. We aimed to conduct an overview of research studies on nPEP and practice in Nigeria from 2002 to 2018 examining: sociodemographic characteristics of study sample, awareness, knowledge and prior use of nPEP, reasons for HIV nPEP, timeliness in presenting for PEP, antiretrovirals (ARVs) used for nPEP, side effects and adherence, monitoring and follow-up visits, adherence to guidelines and recommendations for nPEP by healthcare institutions and the strength of evidence of reviewed studies. METHODS An electronic search on PubMed, PubMed Central (PMC), cumulative Index to Nursing and Allied Health Literature (CINAHL), Scopus, Medline, Embase and Google Scholar for published studies on nPEP from January 2002 to December 2018. We conducted our search using different combinations of the keywords "HIV," "non-occupational," "nonoccupational," "post-exposure," "postexposure," "prophylaxis" and "Nigeria." RESULTS Five articles met the inclusion criteria for this study. About 25.4% of college students were aware of PEP.PEP awareness was significantly determined by the following factors ever tested for HIV, nude picture exchanges, sex without condom, and knowledge of partner's HIV status. Across studies, exposed victims who presented for PEP were mostly females (64%-78%). Rape was the most frequently occurring reason for seeking nPEP (25.9%-64.1%). Although most patients presented for nPEP within 72 hours, follow up visits were generally low (0%-2%) across studies assessed, except for one study that reported a high follow up visit of 83.3%. Guidelines adherence by healthcare institutions could not be established due to lack of information on key variables. CONCLUSION Our study highlights the paucity of research evidence on nPEP use in Nigeria, the societal and cultural contexts in which non-occupational exposures occur, healthcare providers' roles and the public health and practice implications.
