Food insecurity and low CD4 count among HIV-infected people: a systematic review and meta-analysis

Addressing food insecurity in HIV care: perspectives from healthcare and social service providers in New York state

Ending the HIV epidemic in the United States will require addressing social determinants contributing to poor care engagement among people living with HIV (PLH), such as food insecurity. Food insecurity is associated with poor care engagement among PLH. Yet, few studies have examined the perspectives of healthcare and social services providers on addressing food insecurity in HIV care. Guided by the Social Ecological Model, we conducted semi-structured interviews with 18 providers in New York State to understand barriers and facilitators to addressing food insecurity in HIV care. Thematic analysis illustrated eight themes across various levels of the Social Ecological Model. At the patient-level, providers perceived patients' feelings of embarrassment, shame, and judgement, and low health literacy as barriers. At the provider-level, challenges included limited time. Facilitators included fostering strong, patient-provider relationships. Barriers at the clinic-level included limited funding, while clinic resources served as facilitators. At the community-level, challenges included intersecting stigmas arising from community norms towards PLH and people who receive food assistance and limited access to healthy food. Findings suggest the need to incorporate their insights into the development of interventions that address food insecurity in HIV care.

Predictors of Clinical Outcomes among People with HIV and Tuberculosis Symptoms after Rapid Treatment Initiation in Haiti

Introduction

Few studies have evaluated baseline predictors of clinical outcomes among people with HIV starting antiretroviral therapy (ART) in the modern era of rapid ART initiation.

Methods

We conducted a secondary analysis of a randomized controlled trial of two rapid treatment initiation strategies for people with treatment-naïve HIV and tuberculosis symptoms at an urban clinic in Haiti. We used logistic regression models to assess associations between baseline characteristics and (1) retention in care at 48 weeks, (2) HIV viral load suppression at 48 weeks (among participants who underwent viral load testing), and (3) all-cause mortality.

Results

500 participants were enrolled in the study 11/2017-1/2020. Eighty-eight (18%) participants were diagnosed with tuberculosis, and ART was started in 494 (99%). After adjustment, less than secondary education (adjusted odds ratio [AOR] 0.21, 95% CI 0.10-0.46), dolutegravir initiation (AOR 2.57, 95% CI 1.22-5.43), age (AOR 1.42 per 10-year increase, 95% CI 1.01-1.99), and tuberculosis diagnosis (AOR 3.92, 95% CI 1.36-11.28) were significantly associated with retention. Age (AOR 1.36, 95% CI 1.05-1.75), dolutegravir initiation (AOR 1.75, 95% CI 1.07-2.85), and tuberculosis diagnosis (AOR 0.50, 95% CI 0.28-0.89) were associated with viral suppression. Higher CD4 cell count at enrollment (unadjusted odds ratio [OR] 0.69, 95% CI 0.55-0.87) and anemia (OR 4.86, 95% CI 1.71-13.81) were associated with mortality.

Conclusions

We identified sociodemographic, treatment-related, clinical, and laboratory-based predictors of clinical outcomes. These characteristics may serve as markers of sub-populations that could benefit from additional interventions to support treatment success after rapid treatment initiation.

Food and water insecurity in households of children and adolescents living with HIV and receiving care in a rural Zambian hospital: A mixed-methods study

Approximately 62,000 Zambian children are living with HIV. HIV care and treatment is generally more limited in rural areas, where a heavy reliance on rain-fed subsistence agriculture also places households at risk of food and water insecurity. We nested a mixed methods study with an explanatory sequential design in a clinical cohort of children and adolescents living with HIV (CHIV) in rural Zambia. We used validated questionnaires to assess household food and water insecurity and examined associations between indicators derived from those scales, household characteristics, and HIV treatment adherence and outcomes using log-binomial regression. We identified caregivers and older CHIV from food insecure households for in-depth interviews. Of 186 participants completing assessments, 72% lived in moderately or severely food insecure households and 2% in water insecure households. Food insecurity was more prevalent in households of lower socioeconomic status (80% vs. 59% for higher scores; p = 0.02) and where caregivers had completed primary (79%) vs. secondary school or higher (62%; p = 0.01). No other characteristics or outcomes were associated with food insecurity. Parents limited both the quality and quantity of foods they consumed to ensure food availability for their CHIV. Coping strategies included taking on piecework or gathering wild foods; livestock ownership was a potential buffer. Accessing sufficient clean water was less of a concern. During periods of drought or service interruption, participants travelled further for drinking water and accessed water for other purposes from alternative sources or reduced water use. Community contributions afforded some protection against service interruptions. Overall, while food insecurity was prevalent, strategies used by parents may have protected children from a measurable impact on HIV care or treatment outcomes. Reinforcing social protection programs by integrating livestock ownership and strengthening water infrastructure may further protect CHIV in the case of more extreme food or water system shocks.

Addressing the Impact of Climate Change on Sexual and Reproductive Health Among Adolescent Girls and Young Women in Low- and Middle-Income Countries

There is an urgent need to better understand the role of climate change on sexual and reproductive health outcomes, particularly among adolescent girls and young women in low- and middle-income countries. Stakeholders at all levels should apply a rights-based, gendered approach to climate action and adaptation.

Unmet Needs for Ancillary Services and Associations with Clinical Outcomes Among Transgender Women with Diagnosed HIV: Medical Monitoring Project, United States, 2015-2020

Purpose: Access to ancillary services-including HIV support services, non-HIV clinical services, and subsistence services-can support care engagement and viral suppression and reduce disparities among people with HIV (PWH). We used representative U.S. data to assess differences in unmet needs for ancillary services between transgender women with HIV and other PWH. In addition, we examined associations between unmet needs and clinical outcomes among transgender women. Methods: We analyzed 2015-2020 Medical Monitoring Project data among transgender women (N = 362), cisgender men (N = 17,319), and cisgender women (N = 6016) with HIV. We reported weighted percentages for characteristics, and reported adjusted prevalence ratios (aPRs) controlling for race/ethnicity and age, and 95% confidence intervals (CI) using logistic regression with predicted marginal means to assess differences between groups. Results: Among transgender women, unmet needs were highest for dental care (24.9%), shelter or housing (13.9%), and transportation assistance (12.6%). Transgender women were more likely than cisgender men to have unmet subsistence needs. Among transgender women, unmet needs for ancillary services were negatively associated with many clinical outcomes after adjusting for age and race/ethnicity. Unmet needs for subsistence services were associated with higher levels of antiretroviral therapy nonadherence (aPR: 1.39; 95% CI: 1.13-1.70) and detectable viral loads (aPR: 1.47; 1.09-1.98), emergency room visits (aPR: 1.42; 1.06-1.90), and depression (aPR: 2.74; 1.83-4.10) or anxiety (aPR: 3.20; 2.05-5.00) symptoms. Conclusions: Transgender women with HIV were more likely than cisgender men with HIV to experience unmet needs for subsistence services-likely a reflection of substantial socioeconomic disadvantage. Addressing unmet needs is an essential step for improving care outcomes among transgender women with HIV.

Associations of inter-annual rainfall decreases with subsequent HIV outcomes for persons with HIV on antiretroviral therapy in Southern Africa: a collaborative analysis of cohort studies

BACKGROUND

Periods of droughts can lead to decreased food security, and altered behaviours, potentially affecting outcomes on antiretroviral therapy (ART) among persons with HIV (PWH). We investigated whether decreased rainfall is associated with adverse outcomes among PWH on ART in Southern Africa.

METHODS

Data were combined from 11 clinical cohorts of PWH in Lesotho, Malawi, Mozambique, South Africa, Zambia, and Zimbabwe, participating in the International epidemiology Databases to Evaluate AIDS Southern Africa (IeDEA-SA) collaboration. Adult PWH who had started ART prior to 01/06/2016 and were in follow-up in the year prior to 01/06/2016 were included. Two-year rainfall from June 2014 to May 2016 at the location of each HIV centre was summed and ranked against historical 2-year rainfall amounts (1981-2016) to give an empirical relative percentile rainfall estimate. The IeDEA-SA and rainfall data were combined using each HIV centre's latitude/longitude. In individual-level analyses, multivariable Cox or generalized estimating equation regression models (GEEs) assessed associations between decreased rainfall versus historical levels and four separate outcomes (mortality, CD4 counts < 200 cells/mm3, viral loads > 400 copies/mL, and > 12-month gaps in follow-up) in the two years following the rainfall period. GEEs were used to investigate the association between relative rainfall and monthly numbers of unique visitors per HIV centre.

RESULTS

Among 270,708 PWH across 386 HIV centres (67% female, median age 39 [IQR: 32-46]), lower rainfall than usual was associated with higher mortality (adjusted Hazard Ratio: 1.18 [95%CI: 1.07-1.32] per 10 percentile rainfall rank decrease) and unsuppressed viral loads (adjusted Odds Ratio: 1.05 [1.01-1.09]). Levels of rainfall were not strongly associated with CD4 counts < 200 cell/mm3 or > 12-month gaps in care. HIV centres in areas with less rainfall than usual had lower numbers of PWH visiting them (adjusted Rate Ratio: 0.80 [0.66-0.98] per 10 percentile rainfall rank decrease).

CONCLUSIONS

Decreased rainfall could negatively impact on HIV treatment behaviours and outcomes. Further research is needed to explore the reasons for these effects. Interventions to mitigate the health impact of severe weather events are required.

Food Insecurity at HIV Diagnosis Associated with Subsequent Viremia Amongst Adults Living with HIV in an Urban Township of South Africa

We assessed the temporal impact of food insecurity on 12-month antiretroviral (ART) adherence, retention in care, hospitalization, and HIV viremia (> 1000 copies/mL) in ART naïve adults presenting for HIV testing in Umlazi, South Africa. At the time of HIV testing and prior to ART initiation, we determined each participants' food security status using the validated Household Food Insecurity Access Scale (HFIAS). Following HIV testing and ART initiation, we then assessed the above outcomes of each study participant at 3-month intervals for a total of 12 months. Among 2,383 participants with HIV in this study, 253 (10.6%) experienced food insecurity. We found that food insecurity is associated with 20% higher adjusted prevalence odd ratios (aPOR) of having HIV viremia (> 1000 copies/mL) at 12 months following initial diagnosis (aPOR 1.2, 95% CI 1.1-1.4). We found no significant differences in ART adherence, retention in care, and hospitalization occurrences between the food secure and food insecure cohorts.

The impact of food insecurity on receipt of care, retention in care, and viral suppression among people living with HIV/AIDS in the United States: a causal mediation analysis

Introduction

Attaining The Joint United Nations Programme on HIV/AIDS 95-95-95 targets to end the HIV epidemic by 2030 will require a greater understanding of the underlying mechanisms influencing care engagement among people living with HIV/AIDS (PLWHA). One such mechanism is food insecurity, defined as limited or uncertain access to food. Food insecurity has been shown to significantly impact HIV outcomes. Yet, few studies have examined the mechanisms through which food insecurity may influence these outcomes. We aimed to examine the effects of nutritional, behavioral, and mental health mechanisms through which food insecurity may impact HIV care continuum outcomes: receipt of care, retention in care, and viral suppression.

Methods

We conducted a cross-sectional study of 200 PLWHA in New York State, United States from May-August 2022. Participants were recruited using convenience sampling methods. Multivariable logistic regression models were conducted to examine the associations between food insecurity and care continuum outcomes (receipt of care, retention in care, viral suppression), adjusting for age, race, ethnicity, education, income, and marital status. Individual causal mediation analyses were conducted to assess whether behavioral, mental health, and nutritional mechanisms mediated the hypothesized associations.

Results

The median age of participants was 30 years (IQR: 27-37 years). The majority self-identified as Black (54.0%), male (55.5%) and straight/heterosexual (63.0%). Increasing severity of food insecurity was associated with greater odds of non-retention in care (aOR: 1.35, 95% CI: 1.07, 1.70) and viral non-suppression (aOR: 1.29, 95% CI: 1.08, 1.54). For the impact of food insecurity on non-retention in care, there was an indirect relationship (natural indirect effect; NIE) mediated through Body Mass Index (BMI) (ORNIE: 1.08, 95% CI: 1.00, 1.18). For viral non-suppression, there was an indirect relationship mediated through BMI (ORNIE: 1.07, 95% CI: 1.00,1.16) and an indirect relationship mediated through depression (ORNIE: 1.27, 95% CI: 1.07, 1.47).

Discussion

Food insecurity was associated with greater odds of non-retention in care and viral non-suppression among PLWHA. Nutritional and mental health pathways are important mediators of these relationships. Results highlight the need for interventions to target these pathways to address food insecurity as an underlying mechanism influencing engagement in HIV care.

Food Insecurity and Transmission Risks Among People with HIV Who Use Substances

Food insecurity (FI) impacts people with HIV (PWH) and those who use substances (i.e. drugs and alcohol). We evaluated the longitudinal association between FI and HIV transmission risks (unprotected sexual contacts and shared needles/syringes). Among 351 PWH who use substances in Russia, 51.6% reported FI and 37.0% past month injection drug use. The mean number of unprotected sexual contacts in the past 90 days was 13.4 (SD 30.1); 9.7% reported sharing needles/syringes in the past month. We did not find a significant association between mild/moderate FI (adjusted IRR = 0.87, 95% CI 0.47, 1.61) or severe FI (aIRR = 0.84, 95% CI 0.46, 1.54; global p = 0.85) and unprotected sexual contacts. We observed a significant association between severe FI and sharing needles/syringes in the past month (adjusted OR = 3.27, 95% CI 1.45, 7.39; p = 0.004), but not between mild/moderate FI and sharing needles/syringes in the past month (aOR = 1.40,95% CI 0.58, 3.38; p = 0.45). These findings suggest that severe FI could be a potential target for interventions to lower HIV transmission.

Structural violence and the uncertainty of viral undetectability for African, Caribbean and Black people living with HIV in Canada: an institutional ethnography

Biomedical advances in healthcare and antiretroviral treatment or therapy (ART) have transformed HIV/AIDS from a death sentence to a manageable chronic disease. Studies demonstrate that people living with HIV who adhere to antiretroviral therapy can achieve viral suppression or undetectability, which is fundamental for optimizing health outcomes, decreasing HIV-related mortality and morbidity, and preventing HIV transmission. African, Caribbean, and Black (ACB) communities in Canada remain structurally disadvantaged and bear a disproportionate burden of HIV despite biomedical advancements in HIV treatment and prevention. This institutional ethnography orients to the concept of 'structural violence' to illuminate how inequities shape the daily experiences of ACB people living with HIV across the HIV care cascade. We conducted textual analysis and in-depth interviews with ACB people living with HIV (n = 20) and health professionals including healthcare providers, social workers, frontline workers, and health policy actors (n = 15). Study findings produce a cumulative understanding that biomedical HIV discourses and practices ignore structural violence embedded in Canada's social fabric, including legislation, policies and institutional practices that produce inequities and shape the social world of Black communities. Findings show that inequities in structural and social determinants of health such as food insecurity, financial and housing instability, homelessness, precarious immigration status, stigma, racial discrimination, anti-Black racism, criminalization of HIV non-disclosure, health systems barriers and privacy concerns intersect to constrain engagement and retention in HIV healthcare and ART adherence, contributing to the uncertainty of achieving and maintaining undetectability and violating their right to health. Biomedical discourses and practices, and inequities reduce Black people to a stigmatized, pathologized, and impoverished detectable viral underclass. Black people perceived as nonadherent to ART and maintain detectable viral loads are considered "bad" patients while privileged individuals who achieve undetectability are considered "good" patients. An effective response to ending HIV/AIDS requires implementing policies and institutional practices that address inequities in structural and social determinants of health among ACB people.

A randomized control trial of high-dose micronutrient-antioxidant supplementation in healthy persons with untreated HIV infection

Background

Although micronutrient and antioxidant supplementation are widely used by persons with human immunodeficiency virus (HIV), a therapeutic role beyond recommended daily allowances (RDA) remains unproven. An oral high-dose micronutrient and antioxidant supplement (Treatment) was compared to an RDA supplement (Control) for time to progressive immunodeficiency or initiation of antiretroviral therapy (ART) in people living with HIV (PLWH).

Methods

This study was a randomized, double-blind, placebo-controlled multicenter clinical trial. PLWH were recruited from Canadian HIV Trials Network sites, and followed quarterly for two years. Eligible participants were asymptomatic, antiretroviral treatment (ART)-naïve, HIV-seropositive adults with a CD4 T lymphocyte count (CD4 count) between 375–750 cells/μL. Participants were randomly allocated 1:1 to receive Treatment or Control supplements. The primary outcome was a composite of time-to-first of confirmed CD4 count below 350 cells/μL, initiation of ART, AIDS-defining illness or death. Primary analysis was by intention-to-treat. Secondary outcomes included CD4 count trajectory from baseline to ART initiation or two years. A Data and Safety Monitoring Board reviewed the study for safety, recruitment and protocol adherence every six months.

Results

Of 171 enrolled participants: 66 (38.6%) experienced a primary outcome: 27 reached a CD4 count below 350 cells/μL, and 57 started ART. There was no significant difference in time-to-first outcome between groups (Hazard Ratio = 1.05; 95%CI: 0.65, 1.70), or in time to any component outcome. Using intent-to-treat censoring, mean annualized rates of CD4 count decline were -42.703 cells/μL and -79.763 cells/μL for Treatment and Control groups, with no statistical difference in the mean change between groups (-37.06 cells/μL/52 weeks, 95%CI: (-93.59, 19.47); p = 0.1993). Accrual was stopped at 171 of the 212 intended participants after an interim analysis for futility, although participant follow-up was completed.

Conclusions

In ART-naïve PLWH, high-dose antioxidant, micronutrient supplementation compared to RDA supplementation had no significant effect on disease progression or ART initiation.

Water Insecurity is Associated with Lack of Viral Suppression and Greater Odds of AIDS-Defining Illnesses Among Adults with HIV in Western Kenya

Reliable access to safe and acceptable water in sufficient quantities (i.e., water security) is important for medication adherence and limiting pathogen exposure, yet prior studies have only considered the role of food security as a social determinant of HIV-related health. Therefore, the objective of this analysis was to assess the relationships between household water insecurity and HIV-related outcomes among adults living with HIV in western Kenya (N = 716). We conducted a cross-sectional analysis of baseline data from Shamba Maisha (NCT02815579), a cluster randomized controlled trial of a multisectoral agricultural and asset loan intervention. Baseline data were collected from June 2016 to December 2017. We assessed associations between water insecurity and HIV-related outcomes, adjusting for clinical and behavioral confounders, including food insecurity. Each five-unit higher household water insecurity score (range: 0-51) was associated with 1.21 higher odds of having a viral load ≥ 1000 copies/mL (95% CI 1.07, 1.36) and 1.26 higher odds of AIDS-defining illness (95% CI 1.11, 1.42). Household water insecurity was not associated with CD4 cell count (B: 0.27; 95% CI -3.59, 13.05). HIV treatment and support programs should consider assessing and addressing water insecurity in addition to food insecurity to optimize HIV outcomes.

HIV Infections and Food Insecurity Among Pregnant Women from Low- and Middle-Income Countries: A Systematic Review and Meta-analysis

There are few studies on the occurrence of food insecurity (FI) in pregnant women living with HIV/AIDS (PrWLWHA). Our objective was to estimate the prevalence of food insecurity among PrWLWHA and to analyse the association between HIV and FI. For this we searched eight databases. We used the prevalence and prevalence ratio (PR) with a 95% confidence interval (CI) as the summary measurements for the meta-analysis. We identified 300 studies, 13 of which were eligible. The prevalence of FI was 64%, ranging between 26% (mild), 33% (moderate) and 27% (severe). People living with HIV/AIDS (PLWHA) had a 23% greater chance of facing FI (PR = 1.23, 95% CI 1.16-1.38) compared to those not living with HIV. The results revealed a high prevalence and positive association with FI among PLWHA, which suggests the need for food security assessments in HIV/AIDS clinical care.

Health-Related Social Needs Among Emergency Department Patients with HIV

Little research has examined the health-related social needs of emergency department (ED) patients who have HIV. We surveyed a random sample of public hospital ED patients and compared the social needs of patients with and without HIV. Social needs were high among all ED patients, but patients with HIV reported significantly higher levels of food insecurity (65.0% vs. 50.3%, p = 0.01) and homelessness or living doubled up (33.8% vs. 21.0%, p < 0.01) than other patients. Our findings suggest the importance of assessing social needs in ED-based interventions for patients with HIV.

Factors associated with non-adherence to antiretroviral therapy among female sex workers living with HIV in Hyderabad, India

We determined factors associated with non-adherence (consuming <90% of monthly antiretroviral therapy) among female sex workers (FSWs). An interviewer-administered questionnaire was used in a sample of 100 South Indian FSWs living with HIV. We examined demographics, food insecurity, side effects, stigma, alcohol/substance use and self-efficacy. Non-adherence was assessed by self-report, pill-count and combined measures. Prevalence ratios and 95% confidence intervals (CIs) were calculated at p-value <0.1. Thirty-seven percent (33/90) of FSWs were non-adherent by pill-count, 29% (28/95) by self-report and 52% (51/99) by the combined measure. Seventy-six percent (76/100) of FSWs reported experience of at least one form of food insecurity in the past six months. In the regression analysis, arrest in the past year was independently associated with the combined measure of non-adherence (crude prevalence ratios 1.7, 95% CI 1.0-2.8). A successful combination adherence intervention should consider several of the socio-behavioral factors identified in this study including arrest and food insecurity.

Food Insecurity and Cognitive Impairment in the Miami Adult Studies on HIV (MASH) Cohort

BACKGROUND

Food insecurity is a social determinant of health associated with cognitive impairments in older adults and people living with HIV (PLWH). Few studies have examined this relation longitudinally, and no studies have explored how the frequency of food insecurity over time may impact cognitive impairment.

OBJECTIVE

This study aimed to examine the impact of food insecurity on cognitive impairment over a 2-y follow-up period in a cohort of people living with and without HIV.

METHODS

This was a 2-y longitudinal analysis of primarily economically disadvantaged, middle-aged, Black, and Hispanic participants from the Miami Adult Studies on HIV (MASH) cohort. Food insecurity was assessed with the USDA Household Food Security Module at baseline and 12- and 24-mo follow-ups. Food insecurity in all 3 assessments was considered persistent food insecurity. Cognitive impairment was assessed with the Mini-Mental State Examination. Statistical analyses consisted of logistic regressions.

RESULTS

A total of 394 participants (247 HIV positive) with 2-y follow-up data were included in this analysis. At baseline, 104 (26.4%) were food-insecure and 58 (14.7%) had cognitive impairment. Very low food security was associated with cognitive impairment at baseline (OR: 3.23; 95% CI: 1.08, 9.65). PLWH not virally suppressed had higher risk for cognitive impairment compared with HIV-uninfected participants (OR: 2.87; 95% CI: 1.15, 7.18). Additionally, baseline food insecurity (OR: 2.28; 95% CI: 1.08, 4.81) and the frequency of food insecurity over time (OR: 1.50 per year; 95% CI: 1.08, 2.10), particularly persistent food insecurity (OR: 3.69; 95% CI: 1.15, 11.83), were associated with cognitive impairment at 2-y follow-up; the results were consistent after excluding cognitively impaired participants at baseline.

CONCLUSIONS

Food insecurity is a significant risk factor for cognitive impairment, particularly among individuals who experience food insecurity frequently or persistently. Screening for food insecurity and interventions to secure access to sufficient, nutritious foods may help delay cognitive decline among socioeconomically disadvantaged individuals.

Improving the measurement of food insecurity among people with HIV in South Africa: a psychometric examination

OBJECTIVE

Food insecurity is a structural barrier to HIV care in peri-urban areas in South Africa (SA), where approximately 80 % of households are moderately or severely food insecure. For people with HIV (PWH), food insecurity is associated with poor antiretroviral therapy adherence and survival rates. Yet, measurement of food insecurity among PWH remains a challenge.

DESIGN

The current study examines the factor structure of the nine-item Household Food Insecurity Access Scale (HFIAS, isiXhosa-translated) among PWH in SA using a restrictive bifactor model.

SETTING

Primary care clinics in Khayelitsha, a peri-urban settlement in Cape Town, SA.

PARTICIPANTS

Participants (n 440) were PWH who received HIV care in Khayelitsha screening for a clinical trial. Most were categorised as severely (n 250, 56·82 %) or moderately (n 107, 24·32 %) food insecure in the past 30 d.

RESULTS

Revised parallel analysis suggested a three-factor structure, which was inadmissible. A two-factor structure was examined but did not adequately fit the data. A two-factor restrictive bifactor model was examined, such that all items loaded on a general factor (food insecurity) and all but two items loaded on one of two specific additional factors, which adequately fit the data (comparative fit index = 0·995, standardised root mean square residual = 0·019). The two specific factors identified were: anxiety/insufficient quality and no food intake. Reliability was adequate (ω = 0·82).

CONCLUSIONS

Results supported the use of a total score, and identified two specific factors of the HFIAS, which may be utilised in future research and intervention development. These findings help identify aspects of food insecurity that may drive relationships between the construct and important HIV-related variables.

The impact of food insecurity on HIV outcomes in Senegal, West Africa: a prospective longitudinal study

BACKGROUND

Understanding the impact of food insecurity on HIV outcomes is critical for the development and implementation of effective, evidence-based interventions to address food insecurity and improve the HIV care cascade. We conducted a prospective, longitudinal study to determine the impact of food insecurity on HIV outcomes in Senegal, West Africa.

METHODS

HIV-infected individuals presenting for care and initiation of ART through the Senegalese National AIDS program in Dakar and Ziguinchor were eligible for enrollment. Data were collected using interviews, clinical evaluations, laboratory analyses, and chart review at enrollment, month 6, and month 12. Logistic regression was used to determine the association between food insecurity and HIV outcomes.

RESULTS

Among the 207 participants in this study, 70% were female and the median age was 37 years. The majority (69%) were food insecure at enrollment, 29% were severely food insecure, and 38% were undernourished. Nearly a third (32%) had no formal education, 23% practiced agriculture, and 40% owned livestock. The median daily food expenditure per person was $0.58. The median round trip transportation time to clinic was 90 min (IQR 30-240). The median cost of transportation to clinic was $1.74. At month 12, 69% were food insecure, 23% were severely food insecure, and 14% were undernourished. At month 12, 43% had not disclosed their HIV status; food insecurity was associated with non-disclosure of HIV-status due to fear of stigmatization and feelings of shame. Severe food insecurity was a strong predictor of loss to follow-up (OR 3.13 [1.08-9.06]) and persistent severe food insecurity was associated with virologic failure (OR 5.14 [1.01-26.29]) and poor adherence to ART 8.00 [1.11-57.57]. Poor nutritional status was associated with poor immunologic recovery (OR 4.24 [1.56-11.47]), virologic failure (OR 3.39 [1.13-10.21]), and death (OR 3.35 [1.40-8.03]).

CONCLUSION

Severity and duration of food insecurity are important factors in understanding the relationship between food insecurity and HIV outcomes. Our findings highlight the importance of nutritional status, socioeconomic opportunity, and self-stigmatization in the complex pathway between food insecurity and HIV outcomes. Interdisciplinary, multisectoral efforts are needed to develop and implement effective interventions to address food insecurity among people living with HIV.

Food Insecurity and T-cell Dysregulation in Women Living With Human Immunodeficiency Virus on Antiretroviral Therapy

BACKGROUND

Food insecurity is associated with increased morbidity and mortality in people with human immunodeficiency virus (HIV) on antiretroviral therapy, but its relationship with immune dysregulation, a hallmark of HIV infection and comorbidity, is unknown.

METHODS

In 241 women participating in the Women's Interagency HIV Study, peripheral blood mononuclear cells were characterized by flow cytometry to identify cell subsets, comprising surface markers of activation (%CD38+HLADR+), senescence (%CD57+CD28-), exhaustion (%PD-1+), and co-stimulation (%CD57- CD28+) on CD4+ and CD8+ T cells. Mixed-effects linear regression models were used to assess the relationships of food insecurity with immune outcomes, accounting for repeated measures at ≤3 study visits and adjusting for sociodemographic and clinical factors.

RESULTS

At the baseline study visit, 71% of participants identified as non-Hispanic Black, 75% were virally suppressed, and 43% experienced food insecurity. Food insecurity was associated with increased activation of CD4+ and CD8+ T cells, increased senescence of CD8+ T cells, and decreased co-stimulation of CD4+ and CD8+ T cells (all P < .05), adjusting for age, race/ethnicity, income, education, substance use, smoking, HIV viral load, and CD4 count. In stratified analyses, the association of food insecurity with CD4+ T-cell activation was more pronounced in women with uncontrolled HIV (viral load >40 copies/mL and CD4 <500 cells/mm3) but remained statistically significant in those with controlled HIV.

CONCLUSIONS

Food insecurity may contribute to the persistent immune activation and senescence in women with HIV on antiretroviral therapy, independently of HIV control. Reducing food insecurity may be important for decreasing non-AIDS-related disease risk in this population.

High magnitude of food insecurity and malnutrition among people living with HIV/AIDS in Ethiopia: A call for integration of food and nutrition security with HIV treatment and care Programme

BACKGROUND

Food insecurity and malnutrition has been reported to have a strong connection with human immunodeficiency viruses (HIV); this is more pervasive in Sub-Saharan Africa including Ethiopia. In this study, we examined the predictors of food insecurity and factors associated with malnutrition among people living with HIV (PLHIV) in Benishangul Gumuz Regional State, Ethiopia.

METHODS

We conducted a cross-sectional study at outpatient antiretroviral therapy (ART) clinics. Data were collected using participant interview, anthropometry, and participants' chart review. Interviews were carried out with 390 PLHIVs who were on antiretroviral treatment follow-up. Four robust multivariate linear regression models were used to identify predictors of food insecurity and factors associated with malnutrition.

RESULTS

The prevalence of food insecurity and malnutrition among PLHIV were found to be 76% and 60%, respectively. The predictors of food insecurity were: urban residence; household dependency; average monthly income below 53.19 USD; poor asset possession; CD4 count below 350 cell/μL; and recurrent episodes of opportunistic infections (OIs). Correspondingly, malnutrition among PLHIV was found strongly associated with: female gender; urban residence; income below 53.19 USD; poor asset possession; duration of less than one year on ART; and recurrent episodes of OIs.

CONCLUSION

The study findings suggest that the higher prevalence of food insecurity and malnutrition among PLHIV underscore: the need for economic and livelihood intervention; addressing contextual factors including the gender dimensions; adoption of nutrition-specific and sensitive interventions; and integration of food and nutrition security with HIV treatment and care programmes.

Social Support Mitigates Negative Impact of Food Insecurity on Antiretroviral Adherence Among Postpartum Women in Western Kenya

Food insecurity (FI), low social support, and low health-related quality of life (HRQoL) are associated with self-reported nonadherence to antiretroviral therapy (ART) among postpartum women, but these relationships have not been evaluated using objective adherence indicators. Hair samples were therefore analyzed among 83 postpartum Kenyan women living with HIV on efavirenz and nevirapine ART drug regimens in an observational cohort (NCT02974972). FI (0-27), social support (0-40), and HRQoL (8-40) in the prior month were also assessed. In multivariable models, each point increase in FI and decrease in HRQoL were associated with a 45.1% (95% CI: -64.3%, -15.6%) and 10.5% decrease (95% CI: 1.0%, 22.1%) in hair ART drug concentrations respectively, when social support was held constant. A significant interaction between social support and FI (β = 0.02, p = 0.017) indicated that greater social support was predicted to mitigate the negative impacts of FI on ART adherence. Addressing these modifiable barriers could improve ART adherence during this critical period.

Financial, Food, and Housing Insecurity Due to Coronavirus Disease 2019 Among At-Risk People With Human Immunodeficiency Virus in a Nonurban Ryan White HIV/AIDS Program Clinic

Coronavirus disease 2019 negatively impacts social determinants of health that contribute to disparities for people with human immunodeficiency virus (HIV). Insecurity of food, housing, and employment increased significantly in April 2020 among patients with lower incomes at a Ryan White HIV/AIDS program clinic in the Southern United States.

Association between household food insecurity and mortality in Canada: a population-based retrospective cohort study

BACKGROUND

Food insecurity affects 1 in 8 households in Canada, with serious health consequences. We investigated the association between household food insecurity and all-cause and cause-specific mortality.

METHODS

We assessed the food insecurity status of Canadian adults using the Canadian Community Health Survey 2005-2017 and identified premature deaths among the survey respondents using the Canadian Vital Statistics Database 2005-2017. Applying Cox survival analyses to the linked data sets, we compared adults' all-cause and cause-specific mortality hazard by their household food insecurity status.

RESULTS

Of the 510 010 adults sampled (3 390 500 person-years), 25 460 died prematurely by 2017. Death rates of food-secure adults and their counterparts experiencing marginal, moderate and severe food insecurity were 736, 752, 834 and 1124 per 100 000 person-years, respectively. The adjusted hazard ratios (HRs) of all-cause premature mortality for marginal, moderate and severe food insecurity were 1.10 (95% confidence interval [CI] 1.03-1.18), 1.11 (95% CI 1.05-1.18) and 1.37 (95% CI 1.27-1.47), respectively. Among adults who died prematurely, those experiencing severe food insecurity died on average 9 years earlier than their food-secure counterparts (age 59.5 v. 68.9 yr). Severe food insecurity was consistently associated with higher mortality across all causes of death except cancers; the association was particularly pronounced for infectious-parasitic diseases (adjusted HR 2.24, 95% CI 1.42-3.55), unintentional injuries (adjusted HR 2.69, 95% CI 2.04-3.56) and suicides (adjusted HR 2.21, 95% CI 1.50-3.24).

INTERPRETATION

Canadian adults from food-insecure households were more likely to die prematurely than their food-secure counterparts. Efforts to reduce premature mortality should consider food insecurity as a relevant social determinant.

The Mediating Role of Depressive Symptoms in the Association Between Food Insecurity and HIV Related Health Outcomes Among HIV-HCV Co-Infected People

Food insecurity may lead to depressive symptoms, which are known to be associated with poor HIV related health outcomes. However, it is unclear to what extent food insecurity 'directly' affects these outcomes. We used data from the Food Security & HIV-HCV Sub-Study of the Canadian Co-Infection Cohort to assess the controlled direct effect. People experiencing severe food insecurity had 1.47 (95% CI 1.04-2.09) times the risk of having detectable HIV viral load and 0.94 (95% CI 0.87-1.02) fold change in CD4 count. After holding depressive symptoms constant, the association between severe food insecurity and HIV viral load was attenuated to a statistically non-significant level (RR 1.36, 95% CI: 0.95-1.96), whereas the association between severe food insecurity and CD4 count was unchanged. Depressive symptoms partially mediate the effect of severe food insecurity on HIV viral suppression; interventions focused on depressive symptoms alone may not be sufficient, however, to eliminate this effect.

Food insecurity and substance use in people with HIV infection and substance use disorder

BACKGROUND

Food insecurity and substance use are common among people living with HIV (PLWH). Substance use may help people cope with hunger and thus be associated with food insecurity, but the association is uncertain. This study assessed whether, in PLWH and substance dependence, if there was an association between food insecurity and substance use.

Methods: We studied adults with HIV and current substance dependence or ever injection drug use interviewed at 12 and 24 months after enrollment in a prospective cohort study. The presence of food insecurity (insufficient food quantity or quality, or anxiety about its availability) was assessed using the Household Food Insecurity Assessment Scale questionnaire (HFIAS). Unhealthy alcohol use was assessed with the Alcohol Use Disorder Identification Test - Consumption (AUDIT-C) and past 30-day other drug use with the Addiction Severity Index. Associations using repeat cross-sectional data from each of two time-points, 12 months apart, from the same participants were tested using generalized estimating equations logistic regressions.

Results: The 233 participants had a mean age of 50 years and 65% were male. At the first interview, 44% reported food insecurity, 40% unhealthy alcohol use, 25% past 30-day cocaine use, and 17% past 30-day illicit opioid use. In analyses adjusted for demographics, social factors, physical and mental health function, and substance use related variables, there was no significant association between food insecurity and unhealthy alcohol use (adjusted odds ratio (aOR) = 1.06 (95% CI: 0.59, 1.87)). Those with food insecurity had higher odds of illicit opioid use (aOR = 2.5 (95% CI: 1.12, 5.58)) and cocaine use (aOR = 1.95 (CI 95%: 1.00, 3.81)).

Conclusion: Food insecurity was not associated with unhealthy alcohol use but was associated with cocaine and illicit opioid use. Given the prevalence and impact substance use has on PLWH, food insecurity should be identified and addressed.

The role of mental health on the relationship between food insecurity and immunologic outcome among people living with HIV in Guangxi, China

Background

Previous studies showed that food insecurity could adversely affect clinical outcomes of people living with HIV (PLWH). The mental health pathways of such effects are suggested in existing literature, but empirical data are limited in resource-limited settings.

Methods

This cross-sectional study aims to explore the role of depressive symptoms and anxiety on the association between food insecurity and CD4 counts among a sample of 2,987 PLWH in Guangxi, China. Path analysis was used to examine a hypothetical model and delta z test was used to assess the indirect effects of food insecurity on CD4 counts through depressive symptoms and anxiety.

Results

The prevalence of food insecurity in this sample was 25.3%, and the median CD4 counts were 318 cells/mm³. In correlation analyses, food insecurity was not directly associated with LogCD4 but was associated with depressive symptoms and anxiety. Path analysis indicated a significant indirect effect from food insecurity to LogCD4 through depressive symptoms, but not anxiety.

Conclusion

Improving mental health among PLWH with food insecurity may be beneficial for treatment outcomes. Besides intervening food insecurity, an intervention targeting depressive symptoms could improve the immunologic outcomes of PLWH.

Money speaks: Reductions in severe food insecurity follow the Canada Child Benefit

Food insecurity is a pervasive public health problem in high income countries, disproportionately affecting households with children. Though it has been strongly linked with socioeconomic status and investments in social protection programs, less is known about its sensitivity to specific policy interventions, particularly among families. We implemented a difference-in-difference (DID) design to assess whether Canadian households with children experienced reductions in food insecurity compared to those without following the roll-out of a new country-wide income transfer program: the Canada Child Benefit (CCB). Data were derived from the 2015-2018 cycles of Canadian Community Health Survey. We used multinomial logistic regressions to test the association between CCB and food insecurity among three samples: households reporting any income (N = 41,455), the median income or less (N = 18,191) and the Low Income Measure (LIM) or less (N = 7579). The prevalence and severity of food insecurity increased with economic vulnerability, and were both consistently higher among households with children. However, they also experienced significantly greater drops in the likelihood of experiencing severe food insecurity following CCB; most dramatically among those reporting the LIM or less (DID: -4.7%, 95% CI: -8.6, -0.7). These results suggest that CCB disproportionately benefited families most susceptible to food insecurity. Furthermore, our findings also indicate that food insecurity may be impacted by even modest changes to economic circumstance, speaking to the potential of income transfers to help people meet their basic needs.

Psychosocial Factors Associated with Food Insufficiency Among People Living with HIV/AIDS (PLWH) Initiating ART in Ethiopia

Food insufficiency is associated with suboptimal HIV treatment outcomes. Less is known about psychosocial correlates of food insufficiency among PLWH. This sample includes 1176 adults initiating antiretroviral therapy at HIV clinics in Ethiopia. Logistic regression modeled the association of psychological distress, social support, and HIV-related stigma with food insufficiency. Among respondents, 21.4% reported frequent food insufficiency. Psychological distress [adjusted odds ratio (aOR) 2.61 (95% CI 1.79, 3.82)], low social support [aOR 2.20 (95% CI 1.57, 3.09)] and enacted stigma [aOR 1.69 (95% CI 1.26, 2.25)] were independently associated with food insufficiency. Food insufficiency interventions should address its accompanying psychosocial context.

Assessing the impact of food insecurity on HIV medication adherence in the context of an integrated care programme for people living with HIV in Vancouver, Canada

OBJECTIVE

Food insecurity, or self-reports of inadequate food access due to limited financial resources, remains prevalent among people living with HIV (PLHIV). We examined the impact of food insecurity on combination antiretroviral therapy (cART) adherence within an integrated care programme that provides services to PLHIV, including two meals per day.

DESIGN

Adjusted OR (aOR) were estimated by generalized estimating equations, quantifying the relationship between food insecurity (exposure) and cART adherence (outcome) with multivariable logistic regression.

SETTING

We drew on survey data collected between February 2014 and March 2016 from the Dr. Peter Centre Study based in Vancouver, Canada.

PARTICIPANTS

The study included 116 PLHIV at baseline, with ninety-nine participants completing a 12-month follow-up interview. The median (quartile 1-quartile 3) age was 46 (39-52) years at baseline and 87 % (n 101) were biologically male at birth.

RESULTS

At baseline, 74 % (n 86) of participants were food insecure (≥2 affirmative responses on Health Canada's Household Food Security Survey Module) and 67 % (n 78) were adherent to cART ≥95 % of the time. In the adjusted regression analysis, food insecurity was associated with suboptimal cART adherence (aOR = 0·47, 95 % CI 0·24, 0·93).

CONCLUSIONS

While food provision may reduce some health-related harms, there remains a relationship between this prevalent experience and suboptimal cART adherence in this integrated care programme. Future studies that elucidate strategies to mitigate food insecurity and its effects on cART adherence among PLHIV in this setting and in other similar environments are necessary.

Sustained Effect of a Community-based Behavioral and Nutrition Intervention on HIV-related Outcomes Among Women Living With HIV in Rural India: A Quasi-experimental Trial

BACKGROUND

Women living with HIV (WLH) in rural communities face challenges to obtaining treatment and accurate disease-related information. Nutritional deficits exacerbate disease progression.

SETTING

WLH were recruited from primary health centers in rural India.

METHOD

A quasi-experimental trial of a comprehensive Accredited Social Health Activist (Asha)-supported intervention compared 4 distinct Asha-based programs [(1) standard education (SE) alone; (2) nutrition education (+NE); (3) nutrition supplements (+NS); or (4) nutrition education and nutrition supplements (+NENS)] on key disease and nutrition-related outcomes [CD4 count, body mass index (BMI), serum albumin, and hemoglobin]. Assessments occurred at baseline, and months 6 (immediately after intervention), 12, and 18. Multilevel modeling examined effects of program (group) over time.

FINDINGS

Among 600 WLH enrolled (n = 150 per arm), mean age, CD4 count, and BMI (kg/m) were 34.31, 447.42, and 20.09, respectively, at baseline. At 18-month follow-up, program 4 (+NENS) experienced greatest improvements in CD4 counts compared with program 1 (+SE) [adjusted difference = 223.81, 95% confidence interval (CI): 170.29 to 277.32]. For BMI, programs 3 (+NS; adjusted difference = 2.33, 95% CI: 1.39 to 3.26) and 4 (+NENS; adjusted difference = 2.14, 95% CI: 1.17 to 3.12) exhibited greater gains compared with program 1 (+SE). Programs 3 and 4 were not significantly different from each other (adjusted difference = -0.18, 95% CI: -1.12 to 0.76). Hemoglobin and serum albumin also improved over time; program 4 (+NENS) exhibited the greatest gains.

CONCLUSIONS

A low-cost Asha-supported behavioral and nutritional intervention improved outcomes for WLH. Gains were sustained at 18-month follow-up. Similar approaches may help improve HIV and other infectious disease-related outcomes in vulnerable populations.

<i>Chuma na Uchizi</i>: A Livelihood Intervention to Increase Food Security of People Living with HIV in Rural Zambia

The objective of this study was to evaluate the impact of Chuma na Uchizi, a livelihood intervention for people living with HIV (PLHIV) in rural Eastern Province, Zambia, on food security. The intervention included cash transfers to purchase income-generating assets, access to a savings account, and life-skills training. The study employed a non-equivalent groups design to compare intervention (n = 50) and control participants (n = 51) who were receiving outpatient care from two comparable health facilities in distinct constituencies in the same geographic area. We collected data before and after implementation of the intervention. Chuma na Uchizi improved access to food. At follow-up, the intervention group reported lower food insecurity scores compared with the control group (β = -5.65; 95% CI - 10.85 --0.45). Livelihood programs for PLHIV are practical and may be a promising approach to address food insecurity and its adverse effects.

Elevated highly sensitive C-reactive protein and d-dimer levels are associated with food insecurity among people living with HIV in Pune, India

OBJECTIVE

To assess the prevalence and determinants of food insecurity among people living with HIV (PLWH) in Pune, India and its association with biomarkers known to confer increased risks of morbidity and mortality in this population.

DESIGN

Cross-sectional analysis assessing food insecurity using the standardized Household Food Insecurity Access Scale. Participants were dichotomized into two groups: food insecure and food secure. Logistic regression models were used to assess associations between socio-economic, demographic, clinical, biochemical factors and food insecurity.

SETTING

Antiretroviral therapy (ART) centre of Byramjee Jeejeebhoy Government Medical College and Sassoon General Hospitals (BJGMC-SGH), Pune, a large publicly funded tertiary and teaching hospital in western India.ParticpantsAdult (≥18 years) PLWH attending the ART centre between September 2015 and May 2016 who had received ART for either ≤7d (ART-naïve) or ≥1 year (ART-experienced).

RESULTS

Food insecurity was reported by 40 % of 483 participants. Independent risk factors (adjusted OR; 95 % CI) included monthly family income &lt;INR 5000 (~70 USD; 13·2; CI 5·4, 32·2) and consuming ≥4 non-vegetarian meals per week (4·7; 1·9, 11·9). High-sensitivity C-reactive protein (hs-CRP) ≥0·33 mg/dl (1·6; 1·04, 2·6) and d-dimer levels 0·19-0·31 µg/ml (1·6; 1·01, 2·6) and ≥0·32 µg/ml (1·9; 1·2, 3·2) were also associated with food insecurity.

CONCLUSIONS

More than a third of the study participants were food insecure. Furthermore, higher hs-CRP and d-dimer levels were associated with food insecurity. Prospective studies are required to understand the relationship between food insecurity, hs-CRP and d-dimer better.

Food insecurity status and mortality among adults in Ontario, Canada

BACKGROUND

Food insecurity is associated with a wide array of negative health outcomes and higher health care costs but there has been no population-based study of the association of food insecurity and mortality in high-income countries.

METHODS

We use cross-sectional population surveys linked to encoded health administrative data. The sample is 90,368 adults, living in Ontario and respondents in the Canadian Community Health Survey (CCHS). The outcome of interest is all-cause mortality at any time after the interview and within four years of the interview. The primary variable of interest is food insecurity status, with individuals classed as "food secure", "marginally food insecure", "moderately food insecure", or "severely food insecure". We use logistic regression models to determine the association of mortality with food insecurity status, adjusting for other social determinants of health.

RESULTS

Using a full set of covariates, in comparison to food secure individuals, the odds of death at any point after the interview are 1.28 (CI = 1.08, 1.52) for marginally food insecure individuals, 1.49 (CI = 1.29, 1.73) for moderately food insecure individuals, and 2.60 (CI = 2.17, 3.12) for severely food insecure individuals. When mortality within four years of the interview is considered, the odds are, respectively, 1.19 (CI = 0.95, 1.50), 1.65 (CI = 1.37, 1.98), and 2.31 (CI = 1.81, 2.93).

INTERPRETATION

These findings demonstrate that food insecurity is associated with higher mortality rates and these higher rates are especially large for the most severe food insecurity category. Efforts to reduce food insecurity should be incorporated into broader public health initiatives to reduce mortality.

Risk Factors for Self-Reported Cholera Within HIV-Affected Households in Rural Haiti

BACKGROUND

Cholera continues to be a major cause of morbidity and mortality worldwide and is now endemic in Haiti since first being introduced in 2010. Cholera and HIV have significant geographic overlap globally, but little is known about the clinical features and risk of cholera among HIV-infected people and their households.

METHODS

We assessed HIV-affected households originally recruited for a randomized controlled trial of food supplements. We assessed for correlation between household and individual factors and reported history of cholera since 2010 using univariable and multivariable analyses.

RESULTS

There were 352 HIV-infected household members, 32 with reported history of medically attended cholera, and 1968 other household members, 55 with reported history of medically attended cholera. Among HIV-infected individuals in this study, no variables correlated with reported history of cholera in univariable analyses. Among all household members, known HIV infection (adjusted odds ratio [AOR], 3.75; 95% CI, 2.43-5.79; P < .0001), source of income in the household (AOR, 1.82; 95% CI, 1.05-3.15; P = .034), time required to fetch water (AOR, 1.07 per 5-minute increase; 95% CI, 1.01-1.12; P = .015), and severe household food insecurity (AOR, 3.23; 95% CI, 1.25-8.34; P = .016) were correlated with reported history of cholera in a multivariable analysis.

CONCLUSIONS

Known HIV infection, source of household income, time required to fetch water, and severe household food insecurity were independently associated with reported history of medically attended cholera in HIV-affected households in rural Haiti. Further research is required to better understand the interactions between HIV and cholera.

Injection drug use, food insecurity, and HIV-HCV co-infection: a longitudinal cohort analysis

Injection drug use (IDU) and food insecurity (FI) are highly prevalent among individuals living with HIV-hepatitis C virus (HCV) co-infection. We quantified the association between IDU and FI among co-infected individuals using biannual data from the Canadian Co-infection Cohort (N = 608, 2012-2015). IDU (in the past six months) and IDU frequency (non-weekly/weekly in the past month) were self-reported. FI (in the past six months) and FI severity (marginal FI, moderate FI, and severe FI) were measured using the Household Food Security Survey Module. Generalized estimating equations were used to estimate risk ratios (RR) quantifying the associations between IDU, IDU frequency, and FI with Poisson regression. The associations between IDU, IDU frequency, and FI severity were quantified by relative-risk ratios (RRR) estimated with multinomial regression. At the first time-point in the analytical sample, 54% of participants experienced FI in the past six months, 31% engaged in IDU in the six months preceding the FI measure, and 24% injected drugs in the past month. After adjustment for confounding, IDU in the past six months (RR = 1.15, 95% confidence interval [CI] = 1.04-1.28) as well as non-weekly (RR = 1.15, 95% CI = 1.02-1.29) and weekly IDU (RR = 1.21, 95% CI = 1.07-1.37) in the past month are associated with FI. Weekly IDU in the past month is also strongly associated with severe FI (RRR = 2.68, 95% CI = 1.47-4.91). Our findings indicate that there is an association between IDU and FI, particularly weekly IDU and severe FI. This suggests that reductions in IDU may mitigate FI, especially severe FI, in this vulnerable subset of the HIV-positive population.

Methadone treatment, severe food insecurity, and HIV-HCV co-infection: A propensity score matching analysis

BACKGROUND

Severe food insecurity (FI) is common among individuals living with HIV-hepatitis C virus (HCV) co-infection. We hypothesize that the injection of opioids is partly responsible for the association between injection drug use and severe FI. Therefore, this analysis examines whether methadone maintenance treatment for opioid dependence is associated with a lower risk of severe FI.

METHODS

We used biannual data from the Canadian Co-infection Cohort (N = 608, 2012-2015). Methadone treatment (exposure) was self-reported and severe FI (outcome) was measured using the Household Food Security Survey Module. To quantify the association between methadone treatment and severe FI, we estimated an average treatment effect on the treated (marginal risk difference [RD]) using propensity score matching.

RESULTS

Among participants, 25% experienced severe FI in the six months preceding the first time-point in the analytical sample and 5% concurrently reported receiving methadone treatment. Injection of opioids in the six months preceding the treatment and outcome measurements was much higher among those who received methadone treatment (39% vs. 12%). Among the treated participants, 97% had injected opioids in their lifetimes. After propensity score matching, the average risk of experiencing severe FI is 12.3 percentage-points lower among those receiving methadone treatment, compared to those who are not receiving treatment (marginal RD = -0.123, 95% CI = -0.230, -0.015).

CONCLUSIONS

After adjustment for socioeconomic, sociodemographic, behavioural, and clinical confounders, methadone treatment is associated with a lower risk of severe FI. This finding suggests that methadone treatment may mitigate severe FI in this vulnerable subset of the HIV-positive population.

Food Insecurity, HIV Disease Progression and Access to Care Among HIV-Infected Russians not on ART

Food insecurity (FI) has been associated with HIV disease progression among people on antiretroviral therapy (ART), presumably a consequence of poor medication adherence. We assessed whether there is a longitudinal association between FI and two primary outcomes reflecting on HIV disease progression (i.e., CD4 count and time to ART initiation) among people not on ART. Analyses used linear mixed effects and Cox models controlling for confounders. In this cohort (n = 310) FI was common (53%). Most (71.3%) reported past month heavy alcohol use and 37.1% reported past month injection drug use. Only 50 participants initiated ART during the study and mean time to ART was 128 days (SD 120). There were no significant differences in CD4 cell count between the groups with mild/moderate FI or severe FI versus those with no FI [adjusted mean difference, mild/moderate insecurity versus no FI -32.5 (95% CI -94.3, 29.3); severe versus no FI -45.5 (95% CI -124.1, 33.0); global p = 0.42]. We found no significant association between FI and longer time to ART initiation (p = 0.36). Food security is a desirable goal for overall health and shown beneficial for those on ART, however it does not appear to be associated with HIV disease progression among those with high prevalence of substance use and not yet on ART.

Injection Drug Use, Unemployment, and Severe Food Insecurity Among HIV-HCV Co-Infected Individuals: A Mediation Analysis

Severe food insecurity (FI), which indicates reduced food intake, is common among HIV-hepatitis C virus (HCV) co-infected individuals. Given the importance of unemployment as a proximal risk factor for FI, this mediation analysis examines a potential mechanism through which injection drug use (IDU) is associated with severe FI. We used biannual data from the Canadian Co-infection Cohort (N = 429 with 3 study visits, 2012-2015). IDU in the past 6 months (exposure) and current unemployment (mediator) were self-reported. Severe FI in the following 6 months (outcome) was measured using the Household Food Security Survey Module. An overall association and a controlled direct effect were estimated using marginal structural models. Among participants, 32% engaged in IDU, 78% were unemployed, and 29% experienced severe FI. After adjustment for confounding and addressing censoring through weighting, the overall association (through all potential pathways) between IDU and severe FI was: risk ratio (RR) = 1.69 (95% confidence interval [CI] = 1.15-2.48). The controlled direct effect (the association through all potential pathways except that of unemployment) was: RR = 1.65 (95% CI = 1.08-2.53). We found evidence of an overall association between IDU and severe FI and estimated a controlled direct effect that is suggestive of pathways from IDU to severe FI that are not mediated by unemployment. Specifically, an overall association and a controlled direct effect that are similar in magnitude suggests that the potential impact of IDU on unemployment is not the primary mechanism through which IDU is associated with severe FI. Therefore, while further research is required to understand the mechanisms linking IDU and severe FI, the strong overall association suggests that reductions in IDU may mitigate severe FI in this vulnerable subset of the HIV-positive population.

Food insecurity may lead to incomplete HIV viral suppression and less immune reconstitution among HIV/hepatitis C virus-coinfected people

OBJECTIVES

The aim of this study was to determine the impact of food insecurity (FI) on HIV viral load and CD4 count among people coinfected with HIV and hepatitis C virus (HCV).

METHODS

This study was conducted using data from the Food Security & HIV-HCV Sub-Study of the Canadian Co-Infection Cohort study. FI was measured using the adult scale of Health Canada's Household Food Security Survey Module and was classified into three categories: food security, moderate food insecurity and severe food insecurity. The association between FI, HIV viral load, and CD4 count was assessed using a stabilized inverse probability weighted marginal structural model.

RESULTS

A total of 725 HIV/HCV-coinfected people with 1973 person-visits over 3 years of follow-up contributed to this study. At baseline, 23% of participants experienced moderate food insecurity and 34% experienced severe food insecurity. The proportion of people with undetectable HIV viral load was 75% and the median CD4 count was 460 [interquartile range (IQR): 300-665] cells/μL. People experiencing severe food insecurity had 1.47 times [95% confidence interval (CI): 1.14, 1.88] the risk of having detectable HIV viral load and a 0.91-fold (95% CI: 0.84, 0.98) increase in CD4 count compared with people who were food secure.

CONCLUSIONS

These findings provide evidence of the negative impact of food insecurity on HIV viral load and CD4 count among HIV/HCV-coinfected people.

Food insecurity, sexual risk behavior, and adherence to antiretroviral therapy among women living with HIV: A systematic review

Gender inequalities shape the experience of food insecurity among women living with HIV (WLHIV). We systematically reviewed the impact of food insecurity on sexual risk behaviors and antiretroviral therapy (ART) adherence among WLHIV. We included qualitative or quantitative peer-reviewed articles, extracted data in duplicate, and assessed rigor. Seven studies, from sub-Saharan Africa, North America, and Europe, met inclusion criteria. Food insecurity was associated with increased sexual risk through transactional sex and inability to negotiate safer sex. Hunger and food insecurity were barriers to ART initiation/adherence. Multidimensional programming and policies should simultaneously address poverty, gender inequality, food insecurity, and HIV.

Micronutrient supplementation in adults with HIV infection

BACKGROUND

Micronutrient deficiencies are common among adults living with HIV disease, particularly in low-income settings where the diet may be low in essential vitamins and minerals. Some micronutrients play critical roles in maintenance of the immune system, and routine supplementation could therefore be beneficial. This is an update of a Cochrane Review previously published in 2010.

OBJECTIVES

To assess whether micronutrient supplements are effective and safe in reducing mortality and HIV-related morbidity of HIV-positive adults (excluding pregnant women).

SEARCH METHODS

We performed literature searches from January 2010 to 18 November 2016 for new randomized controlled trials (RCTs) of micronutrient supplements since the previous review included all trials identified from searches prior to 2010. We searched the CENTRAL (the Cochrane Library), Embase, and PubMed databases. Also we checked the World Health Organization (WHO) International Clinical Trials Registry Platform (ICTRP) and the ClinicalTrials.gov trials registers. We also checked the reference lists of all new included trials.

SELECTION CRITERIA

We included RCTs that compared supplements that contained either single, dual, or multiple micronutrients with placebo, no treatment, or other supplements. We excluded studies that were primarily designed to investigate the role of micronutrients for the treatment of HIV-positive participants with metabolic morbidity related to highly active antiretroviral therapy (HAART). Primary outcomes included all-cause mortality, morbidity, and disease progression.

DATA COLLECTION AND ANALYSIS

Two review authors independently selected trials for inclusion, and appraised trial quality for risk of bias. Where possible, we presented results as risk ratios (RR) for dichotomous variables, as hazard ratios (HRs) for time-to-event data, and as mean differences (MD) for continuous variables, each with 95% confidence intervals (CIs). Since we were often unable to pool the outcome data, we tabulated it for each comparison. We assessed the certainty of the evidence using the GRADE approach.

MAIN RESULTS

We included 33 trials with 10,325 participants, of which 17 trials were new trials. Ten trials compared a daily multiple micronutrient supplement to placebo in doses up to 20 times the dietary reference intake, and one trial compared a daily standard dose with a high daily dose of multivitamins. Nineteen trials compared supplementation with single or dual micronutrients (such as vitamins A and D, zinc, and selenium) to placebo, and three trials compared different dosages or combinations of micronutrients. Multiple micronutrientsWe conducted analyses across antiretroviral therapy (ART)-naive adults (3 trials, 1448 participants), adults on antiretroviral therapy (ART) (1 trial, 400 participants), and ART-naive adults with concurrent active tuberculosis (3 trials, 1429 participants). Routine multiple micronutrient supplementation may have little or no effect on mortality in adults living with HIV (RR 0.91, 95% CI 0.72 to 1.15; 7 trials, 2897 participants, low certainty evidence).Routine supplementation for up to two years may have little or no effect on the average of mean CD4+ cell count (MD 26.40 cells/mm³, 95% CI -22.91 to 75.70; 6 trials, 1581 participants, low certainty evidence), or the average of mean viral load (MD -0.1 log₁₀viral copies, 95% CI -0.26 to 0.06; 4 trials, 840 participants, moderate certainty evidence). One additional trial in ART-naïve adults did report an increase in the time to reach a CD4+ cell count < 250 cells/mm³ after two years of high dose supplementation in Botswana (HR 0.48, 95% CI 0.26 to 0.88; 1 trial, 439 participants). However, the trial authors reported this effect only in the trial arm that received multiple micronutrients plus selenium (not either supplementation alone), which is inconsistent with the findings of other trials that used similar combinations of micronutrients and selenium.In one additional trial that compared high-dose multiple micronutrient supplementation with standard doses in people on ART, peripheral neuropathy was lower with high dose supplements compared to standard dose (incidence rate ratio (IRR) 0.81, 95% CI 0.7 to 0.94; 1 trial, 3418 participants), but the trial was stopped early due to increased adverse events (elevated alanine transaminase (ALT) levels) in the high dose group. Single or dual micronutrientsNone of the trials of single or dual micronutrient supplements were adequately powered to assess for effects on mortality or morbidity outcomes. No clinically significant changes in CD4 cell count (data not pooled, 14 trials, 2370 participants, very low or low certainty evidence) or viral load (data not pooled, seven studies, 1334 participants, very low or low certainty evidence), were reported. Supplementation probably does increase blood concentrations of vitamin D and zinc (data not pooled, vitamin D: 4 trials, 299 participants, zinc: 4 trials, 484 participants, moderate certainty evidence) and may also increase blood concentrations of vitamin A (data not pooled, 3 trials, 495 participants, low certainty evidence), especially in those who are deficient.

AUTHORS' CONCLUSIONS

The analyses of the available trials have not revealed consistent clinically important benefits with routine multiple micronutrient supplementation in people living with HIV. Larger trials might reveal small but important effects.These findings should not be interpreted as a reason to deny micronutrient supplements for people living with HIV where specific deficiencies are found or where the person's diet is insufficient to meet the recommended daily allowance of vitamins and minerals.

Prevalence and Predictors of Food Insecurity among People Living with HIV Enrolled in Antiretroviral Therapy and Livelihood Programs in Two Rural Zambian Hospitals

The objective of this study was to examine the prevalence and predictors of food insecurity among people living with HIV (PLHIV) in two rural communities in Zambia. A cross-sectional sample of 101 PLHIV was surveyed using the Household Food Insecurity Access Scale. In multivariable linear regression models, income, household possessions, and perceived coping strategies were significantly associated with decreased food insecurity. Debt and perceived mental distress were significantly associated with increased food insecurity. Programs that tackle economic disadvantage and its adverse effect on stress may be an appropriate strategy to improve food security of PLHIV in low-resource communities.
