RESUMEN

Community action is broadly recognised as central to comprehensive and effective system responses to pandemics. However, there is uncertainty about how and where communities can be best supported to bolster long-term resilience and preparedness. We applied a typology of community interventions (Community Informing, Consulting, Involving, Collaborating or Empowering-or CICICE) to cover the diverse range of interventions identified across the literature and used this to structure a scoping review addressing three linked topics: (i) how CICICE interventions have been understood and applied in the literature on epidemic and pandemic preparedness; (ii) the spectrum of interventions that have been implemented to strengthen CICICE and (iii) what evidence is available on their effectiveness in influencing preparedness for current and future emergencies. We drew on peer-reviewed and grey literature from the HIV (from 2000) and COVID-19 pandemics and recent public health emergencies of international concern (from 2008), identified through systematic searches in MEDLINE, Scopus, the Cochrane Collaboration database, supplemented by keyword-structured searches in GoogleScholar and websites of relevant global health organisations. Following screening and extraction, key themes were identified using a combined inductive/deductive approach. 130 papers met the criteria for inclusion. Interventions for preparedness were identified across the spectrum of CICICE. Most work on COVID-19 focused on informing and consulting rather than capacity building and empowerment. The literature on HIV was more likely to report interventions emphasising human rights perspectives and empowerment. There was little robust evidence on the role of CICICE interventions in building preparedness. Evidence of effect was most robust for multi-component interventions for HIV prevention and control. Much of the reporting focused on intermediate outcomes, including measures of health service utilisation. We put forward a series of recommendations to help address evidence shortfalls, including clarifying definitions, organising and stratifying interventions by several parameters and strengthening evaluation methods for CICICE.

RESUMEN

Adaptive and adequately resourced health systems are necessary to achieve good health outcomes in post-conflict settings, however domains beyond the health system are also critical to ensure broader wellbeing. This paper focuses on the importance of psychosocial support services for adolescent girls in fragile contexts. Its starting point is that adolescence is a pivotal time in the life course but given the physical, cognitive and emotional changes triggered by the onset of puberty, it can also be a period of heightened sensitivity and vulnerability to trauma, social isolation, bullying by peers, a lack of supportive adults and gender-based and sexual violence. Our findings highlight why humanitarian and biomedical approaches in their current form are inadequate to address these complexities. Drawing on qualitative fieldwork (consisting of in-depth and key informant interviews as well as group discussions in Gaza, Liberia and Sri Lanka involving a total of 386 respondents across the three countries), we argue that going beyond biomedical approaches and considering the social determinants of health, including approaches to tackle discriminatory gendered norms and barriers to service access, are critical for achieving broader health and wellbeing. While all three case study countries are classified as post-conflict, the political economy dynamics vary with associated implications for experiences of psychosocial vulnerabilities and the service environment. The study concludes by reflecting on actions to address psychosocial vulnerabilities facing adolescent girls. These include: tailoring services to ensure gender and age-sensitivity; investing in capacity building of service providers to promote service uptake; and enhancing strategies to regulate and coordinate actors providing mental health and psychosocial support services.

RESUMEN

There is a growing understanding that strong health systems are crucial to sustain progress. Health systems, however, are complex and much of their success depends on factors operating at different levels and outside the health system, including broader governance and political commitment to health and social development priorities. Recognizing these complexities, this article offers a pragmatic approach to exploring the drivers of progress in maternal and child health in Mozambique, Nepal and Rwanda. To do this, the article builds on a semi-systematic literature review and case study findings, designed and analysed using a multi-level framework. At the macro level, governance with effective and committed leaders was found to be vital for achieving positive health outcomes. This was underpinned by clear commitment from donors coupled by a significant increase in funding to the health sector. At the meso level, where policies are operationalized, inter-sectoral partnerships as well as decentralization and task-shifting emerged as critical. At micro (service interface) level, community-centred models and accessible and appropriately trained and incentivized local health providers play a central role in all study countries. The key drivers of progress are multiple, interrelated and transversal in terms of their operation; they are also in a constant state of flux as health systems and contexts develop. Without seeking to offer a blueprint, the study demonstrates that a 'whole-system' approach can help elicit the key drivers of change and potential pathways towards desirable outcomes. Furthermore, understanding the challenges and opportunities that are instrumental to progress at each particular level of a health system can help policy-makers and implementers to navigate this complexity and take action to strengthen health systems.

RESUMEN

Although ART is increasingly accessible and eases some stresses, it creates other challenges including the importance of food security to enhance ART-effectiveness. This paper explores the role livelihood strategies play in achieving food security and maintaining nutritional status among ART patients in Kenya and Zambia. Ongoing quantitative studies exploring adherence to ART in Mombasa, Kenya (n=118) and in Lusaka, Zambia (n=375) were used to identify the relationship between BMI and adherence; an additional set of in-depth interviews with people on ART (n=32) and members of their livelihood networks (n=64) were undertaken. Existing frameworks and scales for measuring food security and a positive deviance approach was used to analyse data. Findings show the majority of people on ART in Zambia are food insecure; similarly most respondents in both countries report missing meals. Snacking is important for dietary intake, especially in Kenya. Most food is purchased in both countries. Having assets is key for achieving livelihood security in both Kenya and Zambia. Food supplementation is critical to survival and for developing social capital since most is shared amongst family members and others. Whilst family and friends are key to an individual's livelihood network, often more significant for daily survival is proximity to people and the ability to act immediately, characteristics most often found amongst neighbours and tenants. In both countries findings show that with ART health has rebounded but livelihoods lag. Similarly, in both countries respondents with high adherence and high BMI are more self-reliant, have multiple income sources and assets; those with low adherence and low BMI have more tenuous livelihoods and were less likely to have farms/gardens. Food supplementation is, therefore, not a long-term solution. Building on existing livelihood strategies represents an alternative for programme managers and policy-makers as do other strategies including supporting skills and asset accumulation.

RESUMEN

Metabolic programming and metabolic imprinting describe early life events, which impact upon on later physiological outcomes. Despite the increasing numbers of papers and studies, the distinction between metabolic programming and metabolic imprinting remains confusing. The former can be defined as a dynamic process whose effects are dependent upon a critical window(s) while the latter can be more strictly associated with imprinting at the genomic level. The clinical end points associated with these phenomena can sometimes be mechanistically explicable in terms of gene expression mediated by epigenetics. The predictivity of outcomes depends on determining if there is causality or association in the context of both early dietary exposure and future health parameters. The use of biomarkers is a key aspect of determining the predictability of later outcome, and the strengths of particular types of biomarkers need to be determined. It has become clear that several important health endpoints are impacted upon by metabolic programming/imprinting. These include the link between perinatal nutrition, nutritional epigenetics and programming at an early developmental stage and its link to a range of future health risks such as CVD and diabetes. In some cases, the evidence base remains patchy and associative, while in others, a more direct causality between early nutrition and later health is clear. In addition, it is also essential to acknowledge the communication to consumers, industry, health care providers, policy-making bodies as well as to the scientific community. In this way, both programming and, eventually, reprogramming can become effective tools to improve health through dietary intervention at specific developmental points.

RESUMEN

BACKGROUND: Because agriculture is the livelihood base for the majority of people affected by AIDS in sub-Saharan Africa, the interactions between AIDS and agriculture, and their implications for policy and programming, are of fundamental importance. OBJECTIVE: This paper summarizes evidence from three RENEWAL (Regional Network on AIDS, Livelihoods, and Food Security) research studies and one policy review on the interactions between AIDS and agriculture in Zambia and their implications for future policy and programming. METHODS: The unit of analysis adopted for each study varies, spanning the individual, household, cluster, and community levels, drawing attention to the wider socioeconomic landscape within which households operate. Results. This paper identifies the ways in which livelihood activities, within the prevailing norms of gender, sexuality, and perceptions of risk in rural Zambia, can influence susceptibility to HIV and how the nature and severity of the subsequent impacts of AIDS are modified by the specific characteristics and initial conditions of households, clusters, and communities. CONCLUSIONS: The findings demonstrate the importance of studying the risks, vulnerabilities, and impacts of the AIDS epidemic in the context of multiple resource flows and relationships between and within households-and in the context of other drivers of vulnerability, some of which interact with HIV and AIDS. The paper addresses several factors that enable or hinder access to formal support programs, and concludes by highlighting the particular importance of engaging communities proactively in the response to HIV and AIDS, to ensure relevance, sustainability, and scale.

RESUMEN

BACKGROUND: In Ecuador, the prevalence of HIV in the general population is approximately 0.3%. However, up to 17% prevalence has been reported among specific groups of homosexual and bisexual men. The objective of this study is to explore correlates of condom use among men who have sex with men (MSM) across eight cities in Ecuador. METHODS: A cross-sectional survey design was used. A questionnaire including variables on sexual behaviour, demographics, and socio-economic characteristics was distributed to a sample of MSM in eight Ecuadorian cities. RESULTS: Information was obtained for 2,594 MSM across the eight cities. The largest subcategory of self-identification was active bisexuals (35%), followed by those who described themselves as "hombrados" (masculine gays, 22%). The mean age was 25 years, and the majority were unmarried (78%), with a median of 10 years of schooling (IQR 7 - 12). Regarding condom use, 55% of those interviewed had unprotected penetrative sex with each of their last three partners, and almost 25% had never used a condom. The most important correlates of condom use were single status, high life-skills rating, and high socio-economic status (RP 5.45, 95% CI 4.26 - 6.37; RP 1.84, 95% CI 1.79 - 1.86, and RP 1.20, 95% CI 1.01 - 1.31, respectively). CONCLUSION: Our data illustrate the urgent need for targeted HIV-prevention programs for MSM populations in Ecuador. MSM have the highest HIV prevalence in the country, and condom use is extremely low. It is imperative that prevention strategies be re-evaluated and re-prioritized to more effectively respond to the Ecuadorian epidemic.

RESUMEN

BACKGROUND: The majority of sex work in India is clandestine due to unfavorable legal environment and discrimination against female sex workers (FSWs). We report data on who these women are and when they get involved with sex work that could assist in increasing the reach of HIV prevention activities for them. METHODS: Detailed documentation of demography and various aspects of sex work was done through confidential interviews of 6648 FSWs in 13 districts in the Indian state of Andhra Pradesh. The demography of FSWs was compared with that of women in the general population. RESULTS: A total of 5010 (75.4%), 1499 (22.5%), and 139 (2.1%) street-, home-, and brothel-based FSWs, respectively, participated. Comparison with women of Andhra Pradesh revealed that the proportion of those aged 20-34 years (75.6%), belonging to scheduled caste (35.3%) and scheduled tribe (10.5%), illiterate (74.7%), and of those separated/divorced (30.7%) was higher among FSWs (p < 0.001). The FSWs engaged in sex work for >5 years were more likely to be non-street-based FSWs, illiterate, living in small urban towns, and to have started sex work between 12-15 years of age. The mean age at starting sex work (21.7 years) and gap between the first vaginal intercourse and the first sexual intercourse in exchange for money (6.6 years) was lower for FSWs in the rural areas as compared with those in large urban areas (23.9 years and 8.8 years, respectively). CONCLUSION: These data highlight that women struggling with illiteracy, lower social status, and less economic opportunities are especially vulnerable to being infected by HIV, as sex work may be one of the few options available to them to earn money. Recommendations for actions are made for long-term impact on reducing the numbers of women being infected by HIV in addition to the current HIV prevention efforts in India.

RESUMEN

OBJECTIVE: Whilst existing data suggests that the HIV epidemic in Ecuador is concentrated amongst men who have sex with men (MSM), there is very little available information on the situation of key populations, i.e. those most at risk of HIV infection and/or transmitting the infection. In particular, there is very little known about sex workers (SWs), their rate of condom use and other behaviors and characteristics with respect to the risk of acquiring sexually transmitted infections (STIs). This study presents findings from a survey carried out with SWs in eight cities in Ecuador. MATERIAL AND METHODS: Using a cross-sectional design, a questionnaire focusing on behaviours, attitudes and socio-economic and demographic characteristics was administered to SWs in eight cities in Ecuador. These eight cities together account for the majority of the population in the country, and they were also identified as the locations with high reported levels of HIV. RESULTS: Information from a total of 2867 SWs was obtained, the majority were captured in their workplaces. Most of SWs interviewed carry out their activities in closed settings dedicated to sex work (i.e. not in the street). The average age of respondents was 28 (95%CI 27-29), and around half of them live with a male partner (married or not). The rate of condom use with the last client was 88% (82% consistently with the last three), whilst with regular partners it was 6%. A high index of life-skills, high socio-economic status and having an official document that allows them to work, were positively associated with condom use with clients (PR [CI95%] 1.40 [1.40-1.40], 1.37 [1.36-1.37], y 7.26 [6.87-7.46], respectively). CONCLUSIONS: Whilst condom use with clients amongst Ecuadorian SWs is high, this diminishes if one analyzes consistent condom use and is notably low with respect to regular partners. Condom use appears to be related to variables that can be linked to interventions, e.g. life-skills and official permission to carry out sex work. It is, therefore, important to tailor interventions for this population so they maximize the likelihood to increase consistent condom use.

RESUMEN

OBJETIVO: Obtener información sobre la tasa de uso del condón y otros comportamientos y características relacionados con el riesgo de adquirir infecciones de transmisión sexual en trabajadoras sexuales (TS) de ocho ciudades del Ecuador. Este estudio presenta resultados de una encuesta realizada con TS en ocho ciudades del Ecuador. MATERIAL Y MÉTODOS: Se trata de un estudio transversal en el que se aplicó un cuestionario de comportamientos, actitudes y características socioeconómicas y demográficas a una muestra de TS en las ocho ciudades del Ecuador que concentran a la mayor parte de la población del país y padecen la mayor problemática en relación con el VIH. RESULTADOS: Se obtuvo información de un total de 2 867 TS, la mayor parte de ellas en sus lugares de trabajo. El mayor porcentaje de las TS entrevistadas realizaba sus actividades en sitios dedicados al comercio sexual. La edad media de las entrevistadas fue de 28 años (IC95 por ciento 27-29) y alrededor de la mitad vivía con parejas masculinas (ya sea casadas o en unión libre). La tasa de uso del condón con el último cliente fue de 88 por ciento (82 por ciento de forma consistente); en cambio, con las parejas regulares fue de 6 por ciento. Un alto índice de habilidades para la vida, mayor nivel socioeconómico y contar con permiso para trabajar se relacionaron de forma positiva con el uso del condón con clientes (RP= 1.40; IC95 por ciento 1.40-1.40; RP= 1.37; IC95 por ciento 1.36-1.37; y RP= 7.26; IC95 por ciento 6.87-7.46, respectivamente). CONCLUSIONES: Si bien el uso del condón de las TS ecuatorianas con clientes es elevado, disminuye si se analiza su consistencia y es sumamente bajo cuando se trata de parejas regulares. La utilización del condón, por otra parte, parece relacionarse con variables sobre las cuales es posible realizar intervenciones para modificarlas, como las habilidades para la vida y el permiso oficial para realizar el trabajo sexual. En ese sentido, es importante realizar intervenciones específicas que incrementen el uso consistente del condón en esta población.

RESUMEN

BACKGROUND: Heterosexual contact is the most common mode of HIV transmission in India that is largely linked to sex work. We assessed the non-use of condoms in sex work and with regular sex partners by female sex workers (FSWs), and identified its associations that could assist in planning HIV prevention programmes. METHODS: Detailed documentation of various aspects of sex work, and sexual behaviour with regular sex partners, was done through confidential interviews for 6,648 FSWs in 13 districts in the Indian state of Andhra Pradesh. Multivariate analysis was done to understand condom non-use with clients. RESULTS: 5,010 (75.4%), 1,499 (22.5%), and 139 (2.1%) FSWs were street-, home-, and brothel-based, respectively. Of the total 6,648 FSWs, 6,165 (92.7%) had penetrative vaginal/anal sex with at least one client in the last 15 days, and of these 2,907 (47.2%; 95% CI 41.2-53.2%) reported non-use of condom with at least one of her last three clients. Lack of knowledge that HIV could be prevented (odds ratio 5.01; 95% CI 4.38-5.73), no access to free condoms (odds ratio 3.45; 95% CI 2.99-3.98), being street-based as compared with brothel-based (odds ratio 3.36; 95% CI 1.87-6.04), and no participation in FSW support groups (odds ratio 2.02; 95% CI 1.50-2.70) were the most significant predictors of condom non-use with clients. Other associations included lower social support, lower income, age >24 years, illiteracy, and living in medium-size urban or rural areas. Of the 2582 who had penetrative sex with regular sex partner within the last 7 days, 2428 (94%; 95% CI 92.1-95.9%) had not used condom at last sex, and 1032 (41.8%) had neither used condom consistently with clients nor with regular sex partner. CONCLUSION: About half the FSWs do not use condom consistently with their clients in this Indian state putting them at high risk of HIV infection. Non-brothel-based FSWs, who form the majority of sex workers in India, were at a significantly higher risk of HIV infection as compared with brothel-based FSWs. With their high vulnerability, the success of expansion of HIV prevention efforts will depend on achieving and sustaining an environment that enables HIV prevention with the non-brothel based FSWs.
