RESUMEN

BACKGROUND: Food insecurity and HIV-related stigma negatively affect HIV outcomes. Few studies have examined how food security interventions affect HIV-related stigma and social support. SETTING: Two HIV clinics in the Dominican Republic. METHODS: A pilot cluster randomized controlled trial of an urban gardens and peer nutritional counseling intervention was conducted to examine outcomes of HIV-related stigmas and social support. Adult patients (≥18 years of age) with moderate or severe household food insecurity and evidence of suboptimal ART adherence and/or a detectable viral load were enrolled; standard measures of internalized and experienced stigmas and social support were collected at baseline and at 6 and 12 months. Intervention clinic participants received training and materials from agronomists for a home garden, 3-4 sessions of nutritional counseling from the clinic's peer counselor, and a garden produce cooking workshop facilitated by professional nutritionists. RESULTS: Of 109 study participants (46 intervention and 63 control), 103 (94%) completed 12-month follow-up. Difference-in-differences multivariate longitudinal linear regressions adjusting for sociodemographic factors found that intervention participants had reduced internalized stigma by 3.04 points (scale 0-32) at 12 months (P = 0.002); reduced probability of experiencing HIV-related stigma or discrimination in the past 6 months (20 percentage points at 6 months, P = 0.05 and 25 percentage points at 12 months, P = 0.02); and modestly improved social support at 12 months (1.85 points on 30-pt scale, P = 0.093). CONCLUSION: A fully powered, larger trial is needed to establish the efficacy of the intervention and assess pathways by which the intervention may improve HIV stigma and social support.

RESUMEN

OBJECTIVE: Explore participants' perceptions of urban gardens and peer nutritional counseling intervention for people with HIV and food insecurity on antiretroviral therapy in the Dominican Republic. METHODS: Semistructured endline interviews (n = 21) with intervention participants about their perceptions of diet, health, and quality of life. A codebook was applied to verbatim transcripts, and coded data were analyzed using matrices to identify themes. RESULTS: Participants were mostly Dominican (86%; 14% Haitian); 57% were men; the mean age was 45 years. The most salient experiences described by intervention participants were improved dietary quality and diversity, improved food security, and saving money. Participants also emphasized improved social interactions, mental health, and emotional well-being. CONCLUSIONS AND IMPLICATIONS: Urban gardens and peer nutritional counseling may improve participants' diet and psychosocial well-being. Nutrition programs with marginalized populations may need to improve access to healthy foods and build camaraderie and linkages to programs addressing structural factors.

RESUMEN

OBJECTIVE: Food security interventions with people living with HIV (PLHIV) are needed to improve HIV outcomes. This process evaluation of a pilot intervention involving urban gardening and peer nutritional counselling with PLHIV assesses feasibility, acceptability and implementation challenges to inform scale-up. DESIGN: Mixed methods were used, including quantitative data on intervention participation and feasibility and acceptability among participants (n 45) and qualitative data from a purposive sample of participants (n 21). Audio-recorded interviews were transcribed and coded using a codebook developed iteratively. SETTING: An HIV clinic in the northwest-central part of the Dominican Republic. RESULTS: The intervention was feasible for most participants: 84 % attended a garden workshop and 71 % established an urban garden; 91 % received all three core nutritional counselling sessions; and 73 % attended the cooking workshop. The intervention was also highly acceptable: nearly, all participants (93-96 %) rated the gardening as 'helpful' or 'very helpful' for taking HIV medications, their mental/emotional well-being and staying healthy; similarly, high percentages (89-97 %) rated the nutrition counselling 'helpful' or 'very helpful' for following a healthy diet, reducing unhealthy foods and increasing fruit/vegetable intake. Garden barriers included lack of space and animals/pests. Transportation barriers impeded nutritional counselling. Harvested veggies were consumed by participants' households, shared with neighbours and family, and sold in the community. Many emphasised that comradery with other PLHIV helped them cope with HIV-related marginalisation. CONCLUSION: An urban gardens and peer nutritional counselling intervention with PLHIV was feasible and acceptable; however, addressing issues of transportation, pests and space is necessary for equitable participation and benefit.

RESUMEN

HIV-related stigma can affect health by compromising coping and social support. Gender differences in stigma experiences and social support are underexplored, particularly in the Caribbean. We conducted semi-structured interviews (N = 32) with patients at two HIV clinics in the Dominican Republic. Transcripts were coded using qualitative content analysis (deductive and inductive approaches) to identify themes regarding stigma experiences and social support, which were then compared across men and women participants to identify gender differences. While both men and women described experienced stigma, including verbal abuse, men's experience of stigma were subtler and women described outright rejection and instances of physical violence, including intimate partner violence. Both men and women described job discrimination, but women described severe disempowerment as well as permanent loss of income and/or employment whereas men described temporary changes in employment and /or decrease in income. Men and women described modifying behavior due to anticipated stigma, but only women discussed isolating themselves and discomfort taking HIV medication in front of others. Regarding internalized stigma, both men and women described shame, guilt, and depression over their HIV status, though these experiences were more common among women. Women's experiences prevented health care seeking and included suicidality, while men sometimes blamed women for their HIV status and expressed a desire to "move on" and "look ahead." Both men and women described receiving financial support from family and friends, community support from neighbors, governmental support, and support from other people living with HIV. Women most frequently discussed receiving support from family and friends and using religiosity to cope, whereas men referenced general family support and government benefits and were less forthcoming about personal relationships and social networks, oftentimes not disclosing HIV status to others. The social context of HIV-related stigma affects women and men differently with physical and mental health impacts and may require distinct mitigation approaches.

RESUMEN

People living with HIV and a non-communicable disease (NCD) experience multi-level barriers when co-managing multiple conditions. We explored the factors affecting living with multiple chronic conditions in the Dominican Republic. We conducted 21 in-depth interviews from October 2019-February 2020 with Dominican adults who participated in a food security intervention and managed HIV and at least one chronic NCD. Using thematic analysis, we explored participant lived experiences co-managing multiple chronic conditions. All participants (mean age = 45.5 years) were linked to HIV care, but only three were linked to NCD-specific care. Individual-level barriers to managing NCDs included limited education and limited self-efficacy for self-management. Interpersonally, barriers included limited rapport building with an NCD-specific specialist. Structural barriers to managing NCDs were no health insurance, poor referral systems, and limited financial assistance. Health system adaptation requires equitably considering the needs of individuals managing multiple chronic conditions. Key factors to address include patient-provider relationships, improved referral systems, accessibility and availability of specialists, and financial assistance.

RESUMEN

A pilot cluster randomized controlled trial involving two HIV clinics in the Dominican Republic assessed preliminary efficacy of an urban garden and peer nutritional counseling intervention. A total of 115 participants (52 intervention, 63 control) with moderate or severe food insecurity and sub-optimal antiretroviral therapy (ART) adherence and/or detectable viral load were assessed at baseline, 6- and 12-months. Longitudinal multivariate regression analysis controlling for socio-demographics and accounting for serial cluster correlation found that the intervention: reduced the prevalence of detectable viral load by 20 percentage points at 12 months; reduced any missed clinic appointments by 34 and 16 percentage points at 6 and 12 months; increased the probability of "perfect" ART adherence by 24 and 20 percentage points at 6 and 12 months; and decreased food insecurity at 6 and 12 months. Results are promising and warrant a larger controlled trial to establish intervention efficacy for improving HIV clinical outcomes.Trial registry Clinical Trials Identifier: NCT03568682.


RESUMEN: Un estudio piloto de un ensayo controlado aleatorio por conglomerados que involucró a dos clínicas del VIH en la República Dominicana evaluó de forma preliminar la eficacia de una intervención de huertos urbanos y consejería nutricional entre pares. Un total de 115 participantes (52 de intervención, 63 de control) con inseguridad alimentaria moderada o grave y con adherencia subóptima a la terapia antirretroviral (TARV) y/o carga viral detectable fueron evaluados al inicio del estudio, y a los 6 y 12 meses. El análisis de regresión longitudinal multivariada controlando por variables sociodemográficas y tomando en cuenta la correlación serial de clúster encontró que la intervención: redujo la prevalencia de carga viral detectable en 20 puntos porcentuales a los 12 meses; redujo las citas clínicas perdidas en 34 y 16 puntos porcentuales a los 6 y 12 meses; aumentó la probabilidad de adherencia "perfecta" al TARV en 24 y 20 puntos porcentuales a los 6 y 12 meses; y disminuyó la inseguridad alimentaria a los 6 y 12 meses. Los resultados son prometedores y justifican un ensayo controlado más grande para establecer la eficacia de la intervención en mejorar los resultados clínicos del VIH.

RESUMEN

Understanding factors related to suboptimal adherence to antiretroviral therapy (ART) and detectable viral load (VL), especially among vulnerable populations, is needed to improve HIV outcomes. The Caribbean is highly impacted by HIV and socioeconomic inequalities, but few studies have been conducted there to explore food insecurity among people with HIV and factors associated with viral suppression in this vulnerable population. Using baseline data from a pilot intervention trial among people living with HIV and food insecurity in the Dominican Republic, we examined psychosocial and behavioral factors associated with viral suppression, ART adherence, and competing needs. Among participants (n = 115), 61% had a detectable VL; the strongest factor associated with detectable VL was having missed taking ART in the last six months due to not having food (OR = 2.68, p = 0.02). Greater odds of reporting missed ART doses due to not having food were associated with severe food insecurity (OR = 4.60, p = 0.006), clinical depression (OR = 2.76, p = 0.018), Haitian background (OR = 6.62 p = 0.017), and internalized HIV stigma (OR = 1.09, p = 0.041), while lower odds were associated with social support (OR = 0.89, p = 0.03) and having health insurance (OR = 0.27, p = 0.017). Ensuring that people with HIV and food insecurity have food to take with their ART is essential for viral suppression.

RESUMEN

Food insecurity negatively affects HIV prevention and care, and sustainable interventions are needed. Here we describe the development of an integrated urban gardens and peer nutritional counseling intervention to address food insecurity and nutrition among people with HIV, which included: (1) peer nutritional counseling, (2) gardening training, and (3) garden-based nutrition and cooking workshops. The intervention was developed using community-based participatory research over multiple years and stages of data gathering and implementation and evaluation. Lessons learned include the importance of cross-sectoral partnerships to achieve multifaceted, integrated, and sustainable interventions and a shared commitment among partners to an ongoing cycle of action-oriented research, and the need for home-based and community-based gardens to enhance food security and social support. The development process successfully combined an evidence-based framework and community engagement to yield a multicomponent yet integrated food security and nutrition intervention appropriate for people with HIV and potentially adaptable for other chronic conditions.

RESUMEN

OBJECTIVE: The current study aimed to understand how moderate and severe food-insecure people living with HIV (PLHIV) in the Dominican Republic perceive a healthy diet and explore facilitators and barriers to engaging in healthy dietary behaviours as a means of HIV self-management. DESIGN: We conducted semi-structured interviews with PLHIV. We generated codes on food insecurity among PLHIV and used content analysis to organise codes for constant comparison between and within participants. SETTING: Two urban HIV clinics in the Dominican Republic. PARTICIPANTS: Thirty-two PLHIV participated in the interviews. RESULTS: Factors that contributed to dietary behaviours include individual factors, such as knowledge of nutrition, views and attitudes on healthy dietary behaviours, beliefs about dietary needs for PLHIV and diet functionality. Interpersonal factors, including assistance from family and peers in providing food or funds, were deemed critical along with community and organisational factors, such as food assistance from HIV clinics, accessibility to a variety of food store types and the availability of diverse food options at food stores. Policy-level factors that influenced dietary behaviours were contingent on respondents' participation in the labour market (i.e. whether they were employed) and consistent access to government assistance. Food insecurity influenced these factors through unpredictability and a lack of control. CONCLUSIONS: PLHIV who experience food insecurity face various barriers to engaging in healthy dietary behaviours. Their diets are influenced at multiple levels of influence ranging from individual to structural, requiring multi-level interventions that can address these factors concurrently.

RESUMEN

BACKGROUND: Vitamin A deficiency is a risk factor for blindness and for mortality from measles and diarrhoea in children aged 6-59 months. We aimed to estimate trends in the prevalence of vitamin A deficiency between 1991 and 2013 and its mortality burden in low-income and middle-income countries. METHODS: We collated 134 population-representative data sources from 83 countries with measured serum retinol concentration data. We used a Bayesian hierarchical model to estimate the prevalence of vitamin A deficiency, defined as a serum retinol concentration lower than 0·70 µmol/L. We estimated the relative risks (RRs) for the effects of vitamin A deficiency on mortality from measles and diarrhoea by pooling effect sizes from randomised trials of vitamin A supplementation. We used information about prevalences of deficiency, RRs, and number of cause-specific child deaths to estimate deaths attributable to vitamin A deficiency. All analyses included a systematic quantification of uncertainty. FINDINGS: In 1991, 39% (95% credible interval 27-52) of children aged 6-59 months in low-income and middle-income countries were vitamin A deficient. In 2013, the prevalence of deficiency was 29% (17-42; posterior probability [PP] of being a true decline=0·81). Vitamin A deficiency significantly declined in east and southeast Asia and Oceania from 42% (19-70) to 6% (1-16; PP>0·99); a decline in Latin America and the Caribbean from 21% (11-33) to 11% (4-23; PP=0·89) also occurred. In 2013, the prevalence of deficiency was highest in sub-Saharan Africa (48%; 25-75) and south Asia (44%; 13-79). 94 500 (54 200-146 800) deaths from diarrhoea and 11 200 (4300-20 500) deaths from measles were attributable to vitamin A deficiency in 2013, which accounted for 1·7% (1·0-2·6) of all deaths in children younger than 5 years in low-income and middle-income countries. More than 95% of these deaths occurred in sub-Saharan Africa and south Asia. INTERPRETATION: Vitamin A deficiency remains prevalent in south Asia and sub-Saharan Africa. Deaths attributable to this deficiency have decreased over time worldwide, and have been almost eliminated in regions other than south Asia and sub-Saharan Africa. This new evidence for both prevalence and absolute burden of vitamin A deficiency should be used to reconsider, and possibly revise, the list of priority countries for high-dose vitamin A supplementation such that a country's priority status takes into account both the prevalence of deficiency and the expected mortality benefits of supplementation.
