Food as harm reduction: barriers, strategies, and opportunities at the intersection of nutrition and drug-related harm

Determinants of psychological distress during the COVID-19 pandemic among people who use drugs in Montreal, Canada

INTRODUCTION

Limited data exists on psychological impacts of the COVID-19 pandemic among people who use drugs (PWUD). This study aimed to determine the prevalence and correlates of severe psychological distress (PD) among PWUD in Montreal around the beginning of the pandemic.

METHODS

We conducted a rapid assessment study from May to December 2020 among PWUD recruited via a community-based cohort of people who inject drugs in Montreal (Hepatitis C cohort [HEPCO], N = 128) and community organisations (N = 98). We analysed self-reported data on changes in drug use behaviours and social determinants since the declaration of COVID-19 as a public health emergency, and assessed past-month PD using the Kessler K6 scale. Multivariable logistic regression was conducted to examine correlates of PD distress (score ≥13).

RESULTS

Of 226 survey participants, a quarter (n = 56) were screened positive for severe PD. In multivariable analyses, age (1-year increment) (adjusted odds ratio = 0.94, 95% confidence interval [0.90, 0.98]) and a decrease in non-injection drug use versus no change (0.26 [0.07, 0.92]) were protective against severe PD, while positive associations were found for any alcohol use in the past 6 months (3.73 [1.42, 9.78]), increased food insecurity (2.88 [1.19, 6.93]) and both moving around between neighbourhoods more (8.71 [2.63, 28.88]) and less (3.03 [1.18, 7.74]) often compared to no change.

DISCUSSION AND CONCLUSIONS

This study documented a high prevalence of severe PD among PWUD during the COVID-19 pandemic compared with pre-COVID-19 data. Social determinants such as food insecurity and mobility issues, alongside demographic and substance use-related factors, were linked to distress. Evidence-based risk mitigation strategies for this population could reduce negative consequences in future pandemics or disruptions.

Harm reduction strategies in acute care for people who use alcohol and/or drugs: A scoping review

BACKGROUND

People who use alcohol and/or drugs (PWUAD) are at higher risk of infectious disease, experiencing stigma, and recurrent hospitalization. Further, they have a higher likelihood of death once hospitalized when compared to people who do not use drugs and/or alcohol. The use of harm reduction strategies within acute care settings has shown promise in alleviating some of the harms experienced by PWUAD. This review aimed to identify and synthesize evidence related to the implementation of harm reduction strategies in acute care settings.

METHODS

A scoping review investigating harm reduction strategies implemented in acute care settings for PWUAD was conducted. A search strategy developed by a JBI-trained specialist was used to search five databases (Medline, Embase, CINAHL, PsychInfo and Scopus). Screening of titles, abstracts and full texts, and data extraction was done in duplicate by two independent reviewers. Discrepancies were resolved by consensus or with a third reviewer. Results were reported narratively and in tables. Both patients and healthcare decision makers contributing to the development of the protocol, article screening, synthesis and feedback of results, and the identification of gaps in the literature.

FINDINGS

The database search identified 14,580 titles, with 59 studies included in this review. A variety of intervention modalities including pharmacological, decision support, safer consumption, early overdose detection and turning a blind eye were identified. Reported outcome measures related to safer use, managed use, and conditions of use. Reported barriers and enablers to implementation related to system and organizational factors, patient-provider communication, and patient and provider perspectives.

CONCLUSION

This review outlines the types of alcohol and/or drug harm reduction strategies, which have been evaluated and/or implemented in acute care settings, the type of outcome measures used in these evaluations and summarizes key barriers and enablers to implementation. This review has the potential to serve as a resource for future harm reduction evaluation and implementation efforts in the context of acute care settings.

Exploring current nutritional programming and resources available to people living with HIV in Canada: a scoping review

OBJECTIVE

The objective of this scoping review was to map the current literature and resources available on nutrition and food programming for people living with HIV in Canada. This review is phase 1 of a 4-phase project, called FoodNOW (Food to eNhance Our Wellness), a community-based nutritional needs assessment of people living with HIV in Nova Scotia, Canada.

INTRODUCTION

People living with HIV may experience nutritional challenges, including nutritional deficiencies associated with the virus, food insecurity, and nutrition-drug interactions. Nutritional programming is often required for optimal care for people living with HIV. The literature, however, has not been sufficiently mapped to create a comprehensive picture of available programming. This review has informed the development of subsequent study phases, and will contribute towards shaping and planning food programs, as well as evaluating the need for subsequent systematic reviews.

INCLUSION CRITERIA

This review considered literature focused on nutrition and food programming and resources in Canada for people living with HIV. People living with HIV of any age, sex, race, gender identity, or sexual orientation, as well as pregnant and lactating people, were included as the population of interest.

METHODS

The databases searched were MEDLINE (Ovid), CINAHL (EBSCO), Academic Search Premier (EBSCO), Social Services Abstracts (ProQuest), and Scopus. Sources of gray literature searched included government and organization websites, and Google searches. The database search was conducted in July 2021, and the gray literature searches were conducted in August and October 2021. Searches were limited to evidence published or translated in English. Two independent reviewers conducted title and abstract screening, and potentially relevant results were retrieved in full. Full-text screening and data extraction was conducted by 2 independent reviewers using a data extraction tool designed specifically for the scoping review objectives and research inclusion criteria, and any conflicts were resolved through discussion. Results are presented in both tabular and diagrammatic formats, with a narrative summary.

RESULTS

A total of 581 results were screened (published and gray literature). A total of 64 results were included in the review. The 6 reasons for exclusion at full-text review were i) not nutrition and food programming (n= 83), ii) not Canadian (n= 37), iii) duplicates (n= 22), iv) not focused on people living with HIV (n= 6), v) conference abstract (n= 1), and vi) not in English (n= 1). A total of 76 resources were located, as some of the 64 included sources offered more than 1 resource. The 76 resources were organized into 6 categories: i) charitable food provision (n = 21; 27.6%), ii) financial aid (n = 14; 18.4%), iii) nutrition care (n =12; 15.8%), iv) providing access to secondary sources (n= 10; 13.2%), v) food and nutrition expertise (n= 10; 13.2%), and vi) population health promotion (n= 9; 11.8%). Recommendations for future research and programming are discussed.

CONCLUSIONS

This scoping review demonstrates that current programming relies heavily on charitable food provision services for people living with HIV and that there is an unequal distribution of resources across Canada. Program expansion to target diverse populations with more equal distribution across Canada may improve overall health outcomes for people living with HIV. Future research is needed to evaluate the effectiveness of available programming and the needs of end users (people living with HIV and their supports). FoodNOW will build on these findings to further explore and address the needs of people living with HIV.

"We just don't have the space for it": Geographies of survival and spatial triage in overdose prevention sites

This study explores the role of Overdose Prevention Sites (OPS) within the geographies of survival of vulnerably housed people who use drugs (PWUD) in Vancouver, British Columbia (BC), Canada. In BC, OPS are low-barrier spaces where people may use drugs under monitoring of trained staff. OPS have been established by people who use drugs, activists, and allied organizations as an emergency measure to prevent overdose deaths. However, OPS have other important uses for PWUD who are vulnerably housed and rely on public spaces for survival. Drawing on two years (2018-2020) of ethnographic fieldwork and interviews with fifty-five people who work at and/or use OPS, we explore how OPS operators negotiated multiple and at times competing uses of service space for everyday survival. Data analysis was guided by critical urban theory to explore the place of OPS within PWUD's geographies of survival, with attention to how different uses of space were negotiated within the context of an illicit drug poisoning crisis and urban control practices that displace and exclude unhoused and vulnerably housed PWUD from the city. We find that OPS accommodated other important potential uses of space for unhoused and vulnerably housed PWUD who relied on public space for survival and were routinely displaced by revanchist urban control strategies. Low-barrier approaches and facility enhancements to OPS improved program accessibility and enabled PWUD to use the sites more broadly to meet survival needs including for mutual-aid, sheltering, and income-generation. However, these secondary uses of OPS presented multiple operational challenges as service volumes increased. We observed processes of 'spatial triage' emerge within sites to manage these challenges, which we characterise as a pragmatic set of rules, procedures, and spatial practices that constrained broader uses of OPS within PWUD's geographies of survival. While spatial triage offered a pragmatic way of prioritizing service delivery to address the most acute survival threats of overdose fatality, these practices had unintended and inequitable impacts on service access. Our findings indicate the need for complementary structural changes as part of overdose responses to reduce the need for spatial triage (i.e., safe, affordable housing and drug decriminalisation) and service innovations to mitigate potential harms (e.g., Expanded drop-in and chill spaces, temporary storage spaces for service user).

"Food engages people, as we know": health care and service providers' experiences of using food as an incentive in HIV care and support in British Columbia, Canada

Food insecurity is widely documented among people living with HIV (PLWH) worldwide, and it presents significant challenges across the spectrum of HIV care and support. In North America, the prevalence of food insecurity among PLWH exceeds 50%. In the province of British Columbia (BC), it exceeds 65%. It comes as no surprise that food has become an essential tool in supporting and engaging with PLWH. Over the past decade, however, a shift has taken place, and food has become an incentive to boost uptake and outcomes of prevention, testing, treatment, and support. To explore this practice, we drew on a qualitative case study of incentives in the care and support of PLWH. This paper presents the findings of a targeted analysis of interviews (N = 25) that discuss food incentives and explores two main themes that shed light on this practice: (1) Using food to engage versus to incentivize and (2) Food is more beneficial and more ethical. Providers perceived food more positively than other incentives, despite the goal remaining somewhat the same. Incentives, such as cash or gift cards, were considered ethically problematic and less helpful (and potentially harmful), whereas food addressed a basic need and felt more ethical.

Food access among people who inject drugs in West Virginia

BACKGROUND

The substance use epidemic in the United States continues to drive high levels of morbidity and mortality, particularly among people who inject drugs (PWID). Poor access to food often co-occurs with drug use and contributes to associated sequelae, such as risks for HIV and diabetes. The objective of this study was to examine factors associated with adequate food access among PWID in a rural Appalachian community.

METHODS

Cross-sectional surveys were used to collect data among PWID aged 18 and older in Cabell County, West Virginia. Frequency of hunger and sociodemographic, structural and drug use characteristics were measured. Adequate food access was defined as reporting 'never' going to bed hungry at night in the past six months. Pearson's χ² and t-tests and multivariable logistic regression were used to identify factors associated with food access.

RESULTS

Only 71 individuals (17%) reported never going to bed hungry at night in the past six months. Adjusted odds of having adequate food access were higher among PWID who completed high school (aOR 2.94; P = 0.010) and usually used drugs alone (aOR 1.97; P = 0.025), and lower among PWID who were female (aOR 0.51; P = 0.037), experienced homelessness (aOR 0.23, P < 0.001), were recently arrested (aOR 0.50 P = 0.047), and engaged in receptive sharing of injection equipment (aOR 0.52, P = 0.035).

CONCLUSIONS

We found extremely low food access in a population of PWID in Appalachia who are vulnerable to overdose and infectious disease transmission. Integrated interventions promoting food access are needed to improve the public health and wellbeing of people who inject drugs in Appalachia.

Foodscape: A scoping review and a research agenda for food security-related studies

Since 1995, the term ‘foodscape’, a contraction of food and landscape, has been used in various research addressing social and spatial disparities in public health and food systems. This article presents a scoping review of the literature examining how this term is employed and framed. We searched publications using the term foodscape in the Web of Science Core Collection, MEDLINE, and Scopus databases. Analyzing 140 publications, we highlight four approaches to the foodscape: (i) Spatial approaches use statistics and spatial analysis to characterize the diversity of urban foodscapes and their impacts on diet and health, at city or neighborhood scales. (ii) Social and cultural approaches at the same scales show that foodscapes are socially shaped and highlight structural inequalities by combining qualitative case studies and quantitative surveys of food procurement practices. (iii) Behavioral approaches generally focus on indoor micro-scales, showing how consumer perceptions of foodscapes explain and determine food behaviors and food education. (iv) Systemic approaches contest the global corporate food regime and promote local, ethical, and sustainable food networks. Thus, although spatial analysis was the first approach to foodscapes, sociocultural, behavioral and systemic approaches are becoming more common. In the spatial approach, the term ‘foodscape’ is synonymous with ‘food environment’. In the three other approaches, ‘foodscape’ and ‘food environment’ are not synonymous. Scholars consider that the foodscape is not an environment external to individuals but a landscape including, perceived, and socially shaped by individuals and policies. They share a systemic way of thinking, considering culture and experience of food as key to improving our understanding of how food systems affect people. Foodscape studies principally address three issues: public health, social justice, and sustainability. The review concludes with a research agenda, arguing that people-based and place-based approaches need to be combined to tackle the complexity of the food-people-territory nexus.

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.

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.
