HIV incidence among non-migrating persons following a household migration event: a population-based, longitudinal study in Uganda.

Background: The impact of migration on HIV risk among non-migrating household members is poorly understood. We measured HIV incidence among non-migrants living in households with and without migrants in Uganda. Methods: We used four survey rounds of data collected from July 2011-May 2018 from non-migrant participants aged 15-49 years in the Rakai Community Cohort Study, an open, population-based cohort. Non-migrants were individuals with no evidence of migration between surveys or at the prior survey. The primary exposure, household migration, was assessed using census data and defined as ≥1 household member migrating in or out of the house from another community between surveys (∼18 months). Incident HIV cases tested positive following a negative result at the preceding visit. Incidence rate ratios (IRR) with 95% confidence intervals were estimated using Poisson regression with generalized estimating equations and robust standard errors. Analyses were stratified by gender, migration into or out of the household, and the relationship between non-migrants and migrants (i.e., any household migration, spouse, child). Findings: Overall, 11,318 non-migrants (5,674 women) were followed for 37,320 person-years. 28% (6,059/21,370) of non-migrant person-visits had recent migration into or out of the household, and 240 HIV incident cases were identified in non-migrating household members. Overall, non-migrants in migrant households were not at greater risk of acquiring HIV. However, HIV incidence among men was significantly higher when the spouse had recently migrated in (adjIRR:2·12;95%CI:1·05-4·27) or out (adjIRR:4·01;95%CI:2·16-7·44) compared to men with no spousal migration. Women with in- and out-migrant spouses also had higher HIV incidence, but results were not statistically significant. Interpretation: HIV incidence is higher among non-migrating persons with migrant spouses, especially men. Targeted HIV testing and prevention interventions such as pre-exposure prophylaxis could be considered for those with migrant spouses. Funding: National Institutes of Health, US Centers for Disease Control and Prevention. Research in context: We searched PubMed for studies focused on HIV acquisition, prevalence or sexual behaviors among non-migrants who lived with migrants in sub-Saharan Africa (SSA) using search terms such as "HIV", "Emigration and Immigration", "family", "spouses", "household", "parents", and "children". Despite high levels of migration and an established association with HIV risk in SSA, there is limited data on the broader societal impacts of migration on HIV acquisition risk among non-migrant populations directly impacted by it.There has been only one published study that has previously evaluated impact of migration on HIV incidence among non-migrating persons in sub-Saharan Africa. This study, which exclusively assessed spousal migration, was conducted in Tanzania more than two decades earlier prior to HIV treatment availability and found that non-migrant men with long-term mobile partners were more than four times as likely to acquire HIV compared to men who had partners that were residents. To the best of our knowledge, this is the first study to examine the effect of non-spousal migration, including any household migration and child migration, on HIV incidence among non-migrants. Added value of this study: In this study, we used data from the Rakai Community Cohort Study (RCCS), a population-based HIV surveillance cohort to measure the impact of migration on HIV incidence for non-migrant household members. The RCCS captures HIV incident events through regular, repeat HIV testing of participants and migration events through household censuses. Our study adds to the current literature by examining the general effect of migration in the household on HIV incidence in addition to child, and spousal migration. Using data from over 11,000 non-migrant individuals, we found that spousal, but not other types of household migration, substantially increased HIV risk among non-migrants, especially among men. Taken together, our results suggest that spousal migration may be associated with an increased risk of HIV acquisition in the period surrounding and immediately after spousal migration. Implications of all the available evidence: Our findings suggest that spousal migration in or out of the household is associated with greater HIV incidence. Targeted HIV testing and prevention interventions such as pre-exposure prophylaxis could be considered for men with migrant spouses.

"A Double Stress": The Mental Health Impacts of the COVID-19 Pandemic Among People Living with HIV in Rakai, Uganda.

Mental health impacts of the COVID-19 pandemic for people living with HIV are poorly understood, especially in low-income settings. We conducted qualitative semi-structured in-depth interviews among people living with HIV (n = 16) and health workers (n = 10) in rural Rakai, southcentral Uganda. Data were analyzed thematically. We found mental stress during COVID-19 was compounded by worry about antiretroviral therapy (ART) access, distress over inadvertent disclosure of HIV status, fear that coronavirus infection would have more severe outcomes for immunocompromised individuals, and exacerbated poverty and economic stress. Mental health support for people living with HIV deserves greater attention during the COVID-19 pandemic and beyond.

Should trained lay providers perform HIV testing? A systematic review to inform World Health Organization guidelines.

New strategies for HIV testing services (HTS) are needed to achieve UN 90-90-90 targets, including diagnosis of 90% of people living with HIV. Task-sharing HTS to trained lay providers may alleviate health worker shortages and better reach target groups. We conducted a systematic review of studies evaluating HTS by lay providers using rapid diagnostic tests (RDTs). Peer-reviewed articles were included if they compared HTS using RDTs performed by trained lay providers to HTS by health professionals, or to no intervention. We also reviewed data on end-users' values and preferences around lay providers preforming HTS. Searching was conducted through 10 online databases, reviewing reference lists, and contacting experts. Screening and data abstraction were conducted in duplicate using systematic methods. Of 6113 unique citations identified, 5 studies were included in the effectiveness review and 6 in the values and preferences review. One US-based randomized trial found patients' uptake of HTS doubled with lay providers (57% vs. 27%, percent difference: 30, 95% confidence interval: 27-32, p < 0.001). In Malawi, a pre/post study showed increases in HTS sites and tests after delegation to lay providers. Studies from Cambodia, Malawi, and South Africa comparing testing quality between lay providers and laboratory staff found little discordance and high sensitivity and specificity (≥98%). Values and preferences studies generally found support for lay providers conducting HTS, particularly in non-hypothetical scenarios. Based on evidence supporting using trained lay providers, a WHO expert panel recommended lay providers be allowed to conduct HTS using HIV RDTs. Uptake of this recommendation could expand HIV testing to more people globally.

Developing WHO guidelines with pragmatic, structured, evidence-based processes: A case study.

Many guidelines, including those produced by the World Health Organisation (WHO), have failed to adhere to rigorous methodological standards. Operational examples of guideline development processes may provide important lessons learned to improve the rigour and quality of future guidelines. To this end, this paper describes the process of developing WHO guidelines on prevention and care interventions for adults and adolescents living with HIV. Using a pragmatic, structured, evidence-based approach, we created an organising committee, identified topics, conducted systematic reviews, identified experts and distributed evidence summaries. Subsequently, 55 global HIV experts drafted and anonymously submitted guideline statements at the beginning of a conference. During the conference, participants voted on statements using scales evaluating appropriateness of the statements, strength of recommendation and level of evidence. After review of voting results, open discussion, re-voting and refinement of statements, a draft version of the guidelines was completed. A post-conference writing team refined the guidelines based on pre-determined guideline writing principles and incorporated external comments into a final document. Successes and challenges of the guideline development process were identified and are used to highlight current issues and debates in developing guidelines with a focus on implications for future guideline development at WHO.

Child guidance as perceived by foster parents and social workers --a research note.

A brief report of findings from a regional study into the conflict and confluence between the attitudes of foster parents and social workers on children's developmental characteristics points to the need for greater discussion of guidance issues between these groups and further research into the nature and effects of their perceptual differences.
