Pathways between food insecurity and glycaemic control in individuals with type 2 diabetes

Patients with diabetes struggling to afford food and control their HbA1c in food-insecure areas in Bronx, NY

OBJECTIVE

To characterise the association between risk of poor glycaemic control and self-reported and area-level food insecurity among adult patients with type 2 diabetes.

DESIGN

We performed a retrospective, observational analysis of cross-sectional data routinely collected within a health system. Logistic regressions estimated the association between glycaemic control and the dual effect of self-reported and area-level measures of food insecurity.

SETTING

The health system included a network of ambulatory primary and speciality care sites and hospitals in Bronx County, NY.

PARTICIPANTS

Patients diagnosed with type 2 diabetes who completed a health-related social need (HRSN) assessment between April 2018 and December 2019.

RESULTS

5500 patients with type 2 diabetes were assessed for HRSN with 7·1 % reporting an unmet food need. Patients with self-reported food needs demonstrated higher odds of having poor glycaemic control compared with those without food needs (adjusted OR (aOR): 1·59, 95 % CI: 1·26, 2·00). However, there was no conclusive evidence that area-level food insecurity alone was a significant predictor of glycaemic control (aOR: 1·15, 95 % CI: 0·96, 1·39). Patients with self-reported food needs residing in food-secure (aOR: 1·83, 95 % CI: 1·22, 2·74) and food-insecure (aOR: 1·72, 95 % CI: 1·25, 2·37) areas showed higher odds of poor glycaemic control than those without self-reported food needs residing in food-secure areas.

CONCLUSIONS

These findings highlight the importance of utilising patient- and area-level social needs data to identify individuals for targeted interventions with increased risk of adverse health outcomes.

Focusing attention on the important association between food insecurity and psychological distress: a systematic review and meta-analysis

BACKGROUND

Food insecurity has involved more than 750 million individuals worldwide. The association of food insecurity with socio-economic factors is also undeniable demand more consideration. Food insecurity will become a global priority by 2030. This systematic review and meta-analysis examined current literature concerning the association between food insecurity and psychological distress.

METHODS

Relevant researches were identified by searching databases including PubMed, EMBASE, Scopus, and Web of Science, ProQuest, and Cochrane Library up to June 2024 without language limitation. Then a snowball search was conducted in the eligible studies. The quality assessment was made through Newcastle-Ottawa Scale.

RESULTS

Data were available from 44 cross-sectional articles for systematic review and 17 eligible articles for meta-analysis with 2,267,012 and 1,953,636 participants, respectively. Findings support the growing segment of literature on the association between food insecurity and psychological distress. The highly represented groups were households with low income. Psychological and diabetic distress was directly associated with food insecurity as it increased the odds of distress to 329% (OR: 3.29; 95% CI: 2.46-4.40). Sleep problems, anxiety, depression, lower life satisfaction, obesity, and a higher rate of smoking were among the secondary outcomes.

CONCLUSION

Food insecurity was a common stressor that can have a negative impact on psychological well-being and even physical health. The findings should be considered in the public health and making policy-making process.

Disparities in Cardiovascular Disease-Related Outcomes Among Cancer Survivors in the United States: A Systematic Review of the Literature

BACKGROUND

Cancer and cardiovascular disease (CVD) are major causes of morbidity and mortality in the United States (US). Cancer survivors have increased risks for CVD and CVD-related mortality due to multiple factors including cancer treatment-related cardiotoxicity. Disparities are rooted in differential exposure to risk factors and social determinants of health (SDOH), including systemic racism. This review aimed to assess SDOH's role in disparities, document CVD-related disparities among US cancer survivors, and identify literature gaps for future research.

METHODS

Following the Peer Review of Electronic Search Strategies (PRESS) guidelines, MEDLINE, PsycINFO, and Scopus were searched on March 15, 2021, with an update conducted on September 26, 2023. Articles screening was performed using the Preferred Reporting Items for Systematic Review and Meta-Analysis (PRISMA) 2020, a pre-defined Population, Exposure, Comparison, Outcomes, and Settings (PECOS) framework, and the Rayyan platform. A modified version of the Newcastle-Ottawa Scale was used to assess the risk of bias, and RAW Graphs for alluvial charts. This review is registered with PROSPERO under ID #CRD42021236460.

RESULTS

Out of 7,719 retrieved articles, 24 were included, and discussed diverse SDOH that contribute to CVD-related disparities among cancer survivors. The 24 included studies had a large combined total sample size (n=7,704,645; median=19,707). While various disparities have been investigated, including rural-urban, sex, socioeconomic status, and age, a notable observation is that non-Hispanic Black cancer survivors experience disproportionately adverse CVD outcomes when compared to non-Hispanic White survivors. This underscores historical racism and discrimination against non-Hispanic Black individuals as fundamental drivers of CVD-related disparities.

CONCLUSIONS

Stakeholders should work to eliminate the root causes of disparities. Clinicians should increase screening for risk factors that exacerbate CVD-related disparities among cancer survivors. Researchers should prioritise the investigation of systemic factors driving disparities in cancer and CVD and develop innovative interventions to mitigate risk in cancer survivors.

The Impact of Providing Material Benefits to Improve Access to Food on Clinical Parameters, Dietary Intake, and Household Food Insecurity in People with Diabetes: A Systematic Review with Narrative Synthesis

The high cost of healthy foods makes maintaining a healthy dietary pattern challenging, particularly among people with diabetes who are experiencing food insecurity. The objectives of this study were to: 1) review evidence on the impact of providing material benefits (e.g., food coupons/vouchers, free food, or financial subsidies/incentives) to improve access to food on clinical parameters, dietary intake, and household food insecurity in people with diabetes, and 2) review relevant economic evidence. Six databases were searched from inception to March 2023 for longitudinal studies with quantitative outcomes. Twenty-one studies were included in the primary review and 2 in the economic analysis. Risk of bias was high in 20 studies and moderate in 1 study. The number of randomized controlled trials and nonrandomized studies reporting statistically significant improvement, alongside Grading of Recommendations Assessment, Development, and Evaluation (GRADE) certainty of the evidence was: HbA1c: 1/6 and 4/12 (very low), systolic blood pressure: 0/3 and 1/8 (very low), diastolic blood pressure: 0/3 and 1/7 (very low), BMI: 0/5 and 2/8 (very low), body weight: 0/0 and 1/3 (very low), hypoglycemia: 1/2 and 1/2 (very low), daily intake of fruits and vegetables: 1/1 and 1/3 (very low), daily intake of whole grains: 0/0 and 0/2 (very low), overall diet quality: 2/2 and 1/1 (low), and household food insecurity: 2/3 and 0/0 (very low). The 2 studies included in the economic analysis showed no difference in Medicare spending from Supplemental Nutrition Assistance Program participation and cost-savings from medically tailored meals in an economic simulation. Overall, providing material benefits to improve access to food for people with diabetes may improve household food insecurity, fruit and vegetable intake, and overall diet quality, but effects on clinical parameters and whole grain intake are unclear. The certainty of evidence was very low to low by GRADE. PROSPERO (CRD42021212951).

Food insecurity and binge eating: A systematic review and meta-analysis

OBJECTIVE

This review synthesized literature on the relationship between food insecurity and binge eating.

METHODS

Relevant studies were identified by searching PubMed, CINAHL, PsycINFO, and gray literature from inception to October 2022. Eligible studies included primary research that assessed the relationship between food insecurity and binge eating. Data extraction was performed independently by two reviewers. Pooled odds ratios and 95% confidence intervals (CI) were obtained from random effect models with the R package meta. Analyses were stratified by binge eating versus binge-eating disorder (BED), study type (cross-sectional vs. longitudinal), and age (adults vs. adolescents).

RESULTS

We included 24 articles that reported on 20 studies, and 13 articles were included in the meta-analysis. Based on the random effects meta-analysis, the odds of adults in the food insecure group having binge eating were 1.66 (95% CI = 1.42, 1.93) times the odds of adults in the food secure group having binge eating. The odds of adults in the food insecure group having BED were 2.70 (95% CI = 1.47, 4.96) times the odds of adults in the food secure group having BED. Insufficient data were available for a meta-analysis on adolescents or longitudinal relationships.

CONCLUSIONS

These findings support that food insecurity is associated with binge eating in adults. There is a need for research to investigate the mechanisms underlying this relationship. Results highlight the importance of screening participants with food insecurity for disordered eating behaviors and vice versa. Future research is needed to examine whether interventions targeting food insecurity may help to mitigate disordered eating behaviors.

PUBLIC SIGNIFICANCE

Food insecurity is a common but under-recognized contributor to binge eating. In this article, we systematically reviewed research that has been published on the relationship between food insecurity and binge eating. We found support that food insecurity should be considered in the prevention and treatment of binge eating.

Structural Racism as an Upstream Social Determinant of Diabetes Outcomes: A Scoping Review

OBJECTIVE

To evaluate the evidence on the role of structural racism as an upstream factor impacting diabetes outcomes, identify current gaps, and recommend areas for future work.

RESEARCH DESIGN AND METHODS

A reproducible search of Medline and Ovid was used. Structural factors based on the World Health Organization social determinants of health framework (governance, macroeconomic policy, social policy, public policy, and cultural and societal values) had to be included as measured variables or contextual factors discussed as upstream influences. Outcomes included 1) hemoglobin A1c (HbA1c), 2) LDL, 3) BMI, 4) quality of life, 5) self-efficacy, 6) mortality, 7) years of life lost, and 8) self-care behaviors.

RESULTS

Thirteen articles were included for final synthesis. Ten studies focused on governance, two on social policies, one on public policies, and one on cultural and societal values. Results highlight significant associations between structural racism and poorer clinical outcomes (HbA1c and blood pressure), worse self-care behaviors (diet and physical activity), lower standards of care, higher mortality, and more years of life lost for adults with diabetes.

CONCLUSIONS

There is a paucity of work investigating the relationship between structural racism and diabetes outcomes. Five areas for future work include 1) more rigorous research on the relationship between structural racism, downstream social determinants, and health outcomes in diabetes, 2) policy assessments specific to diabetes outcomes, 3) research designed to examine pathways and mechanisms of influence, 4) intervention development to mitigate the impact of structural racism, and 5) tracking and monitoring of change over time.

Implementation Support for a Social Risk Screening and Referral Process in Community Health Centers

Evidence is needed about how to effectively support health care providers in implementing screening for social risks (adverse social determinants of health) and providing related referrals meant to address identified social risks. This need is greatest in underresourced care settings. The authors tested whether an implementation support intervention (6 months of technical assistance and coaching study clinics through a five-step implementation process) improved adoption of social risk activities in community health centers (CHCs). Thirty-one CHC clinics were block-randomized to six wedges that occurred sequentially. Over the 45-month study period from March 2018 to December 2021, data were collected for 6 or more months preintervention, the 6-month intervention period, and 6 or more months postintervention. The authors calculated clinic-level monthly rates of social risk screening results that were entered at in-person encounters and rates of social risk-related referrals. Secondary analyses measured impacts on diabetes-related outcomes. Intervention impact was assessed by comparing clinic performance based on whether they had versus had not yet received the intervention in the preintervention period compared with the intervention and postintervention periods. In assessing the results, the authors note that five clinics withdrew from the study for various bandwidth-related reasons. Of the remaining 26, a total of 19 fully or partially completed all 5 implementation steps, and 7 fully or partially completed at least the first 3 steps. Social risk screening was 2.45 times (95% confidence interval [CI], 1.32-4.39) higher during the intervention period compared with the preintervention period; this impact was not sustained postintervention (rate ratio, 2.16; 95% CI, 0.64-7.27). No significant difference was seen in social risk referral rates during the intervention or postintervention periods. The intervention was associated with greater blood pressure control among patients with diabetes and lower rates of diabetes biomarker screening postintervention. All results must be interpreted considering that the Covid-19 pandemic began midway through the trial, which affected care delivery generally and patients at CHCs particularly. Finally, the study results show that adaptive implementation support was effective at temporarily increasing social risk screening. It is possible that the intervention did not adequately address barriers to sustained implementation or that 6 months was not long enough to cement this change. Underresourced clinics may struggle to participate in support activities over longer periods without adequate resources, even if lengthier support is needed. As policies start requiring documentation of social risk activities, safety-net clinics may be unable to meet these requirements without adequate financial and coaching/technical support.

Food Security and Medication Adherence in Young and Middle-Aged Adults with Diabetes

Medication nonadherence in individuals with diabetes can lead to adverse health outcomes. Young and middle-aged adults are more likely to have low food security than other age groups. However, little research has focused on the relationship between food security and medication adherence in this population. The objective of this study was to examine the relationship between food security and medication adherence among young and middle-aged adults with diabetes. This study used 2019 National Health Interview Survey data. Persons were included if they were aged less than 50 and had a diabetes diagnosis. Individuals were categorized as nonadherent to medication if they answered "yes" to one question indicating nonadherence. Food security status was categorized as food secure, low food security, and very low food security. Among adults under age 50 with diabetes, nearly a fifth were categorized as having low or very low food security. Approximately a quarter of the participants were not adherent. Respondents with low food security and very low food security were significantly more likely to be nonadherent to medication than those who were food secure. People with diabetes under the age of 50 who have low or very low food security are at an increased risk for nonadherence to medication.

Medically tailored meals for food insecurity and type 2 diabetes: Protocol for the Food as Medicine for Diabetes (FAME-D) trial

BACKGROUND

Food insecurity is associated with worse glycemic management for individuals with type 2 diabetes mellitus (T2DM), but whether medically tailored meals (MTM), a food insecurity intervention, can improve glycemic management is unclear.

OBJECTIVE

To describe the protocol for a trial assessing whether an MTM plus lifestyle intervention improves hemoglobin A1c (HbA1c) and participant-reported outcomes, relative to a food subsidy (money that can be spent on foods participants choose), for adults with both T2DM and food insecurity.

METHODS

The Food as Medicine for Diabetes (FAME-D) randomized clinical trial (goal n = 200) is a pragmatic trial with an active comparator. Participants, who will have T2DM and report food insecurity, will be randomly assigned to a 6-month MTM plus telephone-delivered lifestyle change intervention, or a 6-month food subsidy ($40/month). The primary outcome is HbA1c at 6 months. Secondary outcomes include HbA1c at 12 months to assess whether the intervention effect (if any) is sustained, along with weight, food insecurity, diabetes distress, and health-related quality of life. Qualitative analyses of semi-structured interviews will help understand why, how, and under what circumstances the intervention achieved its observed results.

CONCLUSION

Results from FAME-D will help inform clinical management of food insecurity when it co-occurs with T2DM. Further, results may be useful as healthcare payors are considering coverage for MTM interventions.

Protocol: Developing a framework to improve glycaemic control among patients with type 2 diabetes mellitus in Kinshasa, Democratic Republic of the Congo

In Kinshasa, Democratic Republic of the Congo (DRC), between 68–86% of patients with type 2 diabetes present with poor glycaemic control leading to increased risk of complications and high cost of care. Identifying the factors driving glycaemic control is essential for better management. There is lack of data on factors associated with poor glycaemic control and targeted interventions in the DRC. This study aims to determine the factors associated with type 2 diabetes control and develop an appropriate intervention package in Kinshasa. The study will comprise of three sub-studies as follows: the first sub-study being a concurrent parallel mixed-methods cross-sectional study to determine factors driving poor glycaemic control among patients in Kinshasa. A total of 614 patients will be invited to participate in a cross-sectional study and respond to standardized questionnaires. A minimum of 20 purposively selected patients will participate in the qualitative study that will involve in-depth interviews about their perspectives on glycaemic control. In the quantitative study, multivariable logistic regression will be performed to determine factors associated with glycaemic control, after identifying the confounding factors. In the qualitative study, thematic analysis will be performed. Findings of the quantitative and qualitative studies on factors that are associated with glycaemic control will be triangulated. And allow to conduct the second sub-study, a qualitative inquiry with a minimum of 20 healthcare providers and 20 patients, selected purposively, to explore their perspectives about potential interventions to improve glycaemic control. At the last, the findings of both sub-studies will be subjected to an anonymous electronic three-round process Delphi study involving 25 stakeholders on the intervention package to develop a framework to optimise glycaemic control in Kinshasa. The implementation of the intervention package will occur after the completion of this study with expected substantial impact on the patients, healthcare providers, and health system.

Cross-Sectional Associations: Social Risks and Diabetes Care Quality, Outcomes

INTRODUCTION

Social risks (e.g., food/transportation insecurity) can hamper type 2 diabetes mellitus (T2DM) self-management, leading to poor outcomes. To determine the extent to which high-quality care can overcome social risks' health impacts, this study assessed the associations between reported social risks, receipt of guideline-based T2DM care, and T2DM outcomes when care is up to date among community health center patients.

METHODS

A cross-sectional study of adults aged ≥18 years (N=73,484) seen at 186 community health centers, with T2DM and ≥1 year of observation between July 2016 and February 2020. Measures of T2DM care included up-to-date HbA1c, microalbuminuria, low-density lipoprotein screening, and foot examination, and active statin prescription when indicated. Measures of T2DM outcomes among patients with up-to-date care included blood pressure, HbA1c, and low-density lipoprotein control on or within 6‒12 months of an index encounter. Analyses were conducted in 2021.

RESULTS

Individuals reporting transportation or housing insecurity were less likely to have up-to-date low-density lipoprotein screening; no other associations were seen between social risks and clinical care quality. Among individuals with up-to-date care, food insecurity was associated with lower adjusted rates of controlled HbA1c (79% vs 75%, p<0.001), and transportation insecurity was associated with lower rates of controlled HbA1c (79% vs 74%, p=0.005), blood pressure (74% vs 72%, p=0.025), and low-density lipoprotein (61% vs 57%, p=0.009) than among those with no reported need.

CONCLUSIONS

Community health center patients received similar care regardless of the presence of social risks. However, even among those up to date on care, social risks were associated with worse T2DM control. Future research should identify strategies for improving HbA1c control for individuals with social risks.

Food Insecurity and Cardiometabolic Conditions: a Review of Recent Research

PURPOSE OF REVIEW

To understand recent literature that examines associations between food insecurity and cardiometabolic conditions and risk factors. We included original research, systematic reviews, and meta-analyses on the topic of food insecurity and cardiometabolic risk published from January 1, 2017, to December 31, 2020. Editorials, perspectives, and case reports were excluded. After the initial search, 3 reviewers selected studies for inclusion based on relevance and methods. Ultimately, fifty studies were included.

RECENT FINDINGS

We included 35 studies of adults (20 cross-sectional observational studies, 5 longitudinal observational studies, 5 interventional studies, and 5 meta-analyses/reviews). In adults, food insecurity is associated with greater prevalence of overweight/obesity (especially for women). It is also associated with hypertension, diabetes (including worse glycemic control and more diabetes complications), coronary heart disease, congestive heart failure, stroke, and chronic kidney disease. We included 15 studies of children (11 cross-sectional observational studies and 4 longitudinal observational studies). In children, findings were more nuanced, and in particular, many studies did not find an association between food insecurity and overweight/obesity. However, authors noted that these conditions may not have had time to develop. With notable exceptions, many studies were cross-sectional, and there were few interventions. There is a robust association between food insecurity and cardiometabolic conditions and risk factors in adults, but the picture is less clear in children. Overt cardiometabolic clinical conditions develop more rarely in children, but childhood experiences may set a trajectory for worse health later in life. Detailed life course epidemiologic studies are needed to better understand this relationship. Future interventions should examine how to reduce the prevalence of food insecurity, and how best to improve health for those who experience food insecurity.

Household food insecurity and health in a high-migration area in rural Honduras

Household food insecurity (HFI) is a significant problem in the developing world. Relationships between HFI and nutrition, physical growth, and development have been elucidated; less is known about the non-nutritional impacts among individuals living in rural areas in low-income countries. The aim of this study was to determine if HFI is a risk factor for suboptimal mental health and overall health in rural Honduras. In a population of 24,696 adults with 176 isolated villages in western Honduras, we collected data on household food insecurity and physical and mental health outcome measures. Using logistic regression with and without adjusting for village and household level unobservables invariant across individual respondents, we show that females (OR: 1.11, p <0.01)), indigenous people (OR: 2:00, p < 0.01), and those planning to migrate (OR: 1.24, p <0.01) have higher odds of experiencing food insecurity. The risks of food insecurity and poor health were mitigated among respondents living where they were born and having multi-generations of relatives living in the same village-a measure of the opportunity and availability of social networks. Living in a food insecure compared to a food secure household was associated with 77 percent higher odds of being depressed, 35 percent higher odds of low overall mental health, and 20 percent higher odds for low overall health.

Food insecurity is associated with magnetic resonance-determined nonalcoholic fatty liver and liver fibrosis in low-income, middle-aged adults with and without HIV

BACKGROUND

Nonalcoholic fatty liver disease (NAFLD) is the most prevalent liver disease in the United States. Food-insecure individuals often depend on low-cost, energy-dense but nutritionally poor foods, resulting in obesity and chronic diseases related to NAFLD.

OBJECTIVES

To determine whether food insecurity is associated with NAFLD in a cohort of HIV and hepatitis C virus (HCV) infected and uninfected adults.

METHODS

We conducted a cross-sectional analysis of low-income, middle-aged adults from the Miami Adult Studies on HIV (MASH) cohort without a history of excessive alcohol consumption. Food security was assessed with the USDA's Household Food Security Survey. MRIs were used to assess liver steatosis and fibrosis. Metabolic parameters were assessed from fasting blood, anthropometrics, and vitals.

RESULTS

Of the total 603 participants, 32.0% reported food insecurity. The prevalences of NAFLD, fibrosis, and advanced fibrosis were 16.1%, 15.1%, and 4.6%, respectively. For every 5 kg/m2 increase in BMI, the odds of NAFLD increased by a factor of 3.83 (95% CI, 2.37-6.19) in food-insecure participants compared to 1.32 (95% CI, 1.04-1.67) in food-secure participants. Food insecurity was associated with increased odds for any liver fibrosis (OR, 1.65; 95% CI, 1.01-2.72) and advanced liver fibrosis (OR, 2.82; 95% CI, 1.22-6.54), adjusted for confounders. HIV and HCV infections were associated with increased risks for fibrosis, but the relationship between food insecurity and liver fibrosis did not differ between infected and uninfected participants.

CONCLUSIONS

Among low-income, middle-aged adults, food insecurity exacerbated the risk for NAFLD associated with a higher BMI and independently increased the risk for advanced liver fibrosis. People who experience food insecurity, particularly those vulnerable to chronic diseases and viral infections, may be at increased risk for liver-related morbidity and mortality. Improving access to adequate nutrition and preventing obesity among low-income groups may lessen the growing burden of NAFLD and other chronic diseases.

A qualitative investigation of lived experiences of long-term health condition management with people who are food insecure

Background

As more people are living with one or more chronic health conditions, supporting patients to become activated, self-managers of their conditions has become a key health policy focus both in the UK and internationally. There is also growing evidence in the UK that those with long term health conditions have an increased risk of being food insecure. While international evidence indicates that food insecurity adversely affects individual’s health condition management capability, little is known about how those so affected manage their condition(s) in this context. An investigation of lived experience of health condition management was undertaken with food insecure people living in north east Scotland. The study aimed to explore the challenges facing food insecure people in terms of, i. their self-care condition management practices, and ii. disclosing and discussing the experience of managing their condition with a health care professional, and iii. Notions of the support they might wish to receive from them.

Methods

Twenty in-depth interviews were conducted with individuals attending a food bank and food pantry in north east Scotland. Interview audio recordings were fully transcribed and thematically analysed.

Results

Individuals reporting multiple physical and mental health conditions, took part in the study. Four main themes were identified i.e.: 1. food practices, trade-offs and compromises, that relate to economic constraints and lack of choice; 2. illness experiences and food as they relate to physical and mental ill-health; 3. (in) visibility of participants’ economic vulnerability within health care consultations; and 4. perceptions and expectations of the health care system.

Conclusions

This study, the first of its kind in the UK, indicated that participants’ health condition management aspirations were undermined by the experience of food insecurity, and that their health care consultations in were, on the whole, devoid of discussions of those challenges. As such, the study indicated practical and ethical implications for health care policy, practice and research associated with the risk of intervention-generated health inequalities that were suggested by this study. Better understanding is needed about the impact of household food insecurity on existing ill health, wellbeing and health care use across the UK.

Emerging trends and the clinical impact of food insecurity in patients with diabetes

Food insecurity is a major public health concern in the United States affecting 15 million households according to data in 2017 from the US Department of Agriculture. Food insecurity, or the inability to consistently obtain nutritious food, disproportionately affects socioeconomically disadvantaged households, as well as those with chronic diseases including diabetes mellitus (DM). This review article explores the literature over the past 10 years pertaining to the complex relationship between food insecurity, social determinants of health, and chronic disease with an emphasis on diabetes and glycemic control. Those with diabetes and food insecurity together have been shown to have worse glycemic control compared to those who are food secure, but it remains unclear exactly how food insecurity affects glycemic control. Prior interventional studies have targeted aspects of food insecurity in patients with diabetes but have reported variable outcomes with respect to improvement in glycemic control despite effectively reducing rates of food insecurity. Additionally, few data exist regarding long-term outcomes and diabetes-related complications in this population. It is likely that many factors at both the community and individual levels impact glycemic control outcomes in the setting of food insecurity. Further studies are needed to better understand these factors and to create multifaceted targets for future interventional studies aimed at improving glycemic control in this population.

Emerging practices supporting diabetes self-management among food insecure adults and families: A scoping review

BACKGROUND

Food insecurity undermines a patient's ability to follow diabetes self-management recommendations. Care providers need strategies to direct their support of diabetes management among food insecure patients and families.

OBJECTIVE

To identify what emerging practices health care providers can relay to patients or operationalize to best support diabetes self-management among food insecure adults and families.

ELIGIBILITY CRITERIA

Food insecure populations with diabetes (type 1, type 2, prediabetes, gestational diabetes) and provided diabetes management practices specifically for food insecure populations. Only studies in English were considered. In total, 21 articles were reviewed.

SOURCES OF EVIDENCE

Seven databases: Cumulative Index of Nursing and Allied Health Literature, Cochrane Database of Systematic Reviews, Medline, ProQuest Nursing & Allied Health Database, PsychInfo, Scopus, and Web of Science.

RESULTS

Emerging practices identified through this review include screening for food insecurity as a first step, followed by tailoring nutrition counseling, preventing hypoglycemia through managing medications, referring patients to professional and community resources, building supportive care provider-patient relationships, developing constructive coping strategies, and decreasing tobacco smoking.

CONCLUSION

Emerging practices identified in our review include screening for food insecurity, nutrition counselling, tailoring management plans through medication adjustments, referring to local resources, improving care provider-patient relationship, promoting healthy coping strategies, and decreasing tobacco use. These strategies can help care providers better support food insecure populations with diabetes. However, some strategies require further evaluation to enhance understanding of their benefits, particularly in food insecure individuals with gestational and prediabetes, as no studies were identified in these populations. A major limitation of this review is the lack of global representation considering no studies outside of North America satisfied our inclusion criteria, due in part to the English language restriction.
