Material need support interventions for diabetes prevention and control: a systematic review

Evaluating Intensity, Complexity, and Potential for Causal Inference in Social Needs Interventions: A Review of a Scoping Review

Importance

Interventions that address needs such as low income, housing instability, and safety are increasingly appearing in the health care sector as part of multifaceted efforts to improve health and health equity, but evidence relevant to scaling these social needs interventions is limited.

Objective

To summarize the intensity and complexity of social needs interventions included in randomized clinical trials (RCTs) and assess whether these RCTs were designed to measure the causal effects of intervention components on behavioral, health, or health care utilization outcomes.

Evidence Review

This review of a scoping review was based on a Patient-Centered Outcomes Research Institute-funded evidence map of English-language US-based RCTs of social needs interventions published between January 1, 1995, and April 6, 2023. Studies were assessed for features related to intensity (defined using modal values as providing as-needed interaction, 8 participant contacts or more, contacts occurring every 2 weeks or more often, encounters of 30 minutes or longer, contacts over 6 months or longer, or home visits), complexity (defined as addressing multiple social needs, having dedicated staff, involving multiple intervention components or practitioners, aiming to change multiple participant behaviors [knowledge, action, or practice], requiring or providing resources or active assistance with resources, and permitting tailoring), and the ability to assess causal inferences of components (assessing interventions, comparators, and context).

Findings

This review of a scoping review of social needs interventions identified 77 RCTs in 93 publications with a total of 135 690 participants. Most articles (68 RCTs [88%]) reported 1 or more features of high intensity. All studies reported 1 or more features indicative of high complexity. Because most studies compared usual care with multicomponent interventions that were moderately or highly dependent on context and individual factors, their designs permitted causal inferences about overall effectiveness but not about individual components.

Conclusions and Relevance

Social needs interventions are complex, intense, and include multiple components. Our findings suggest that RCTs of these interventions address overall intervention effectiveness but are rarely designed to distinguish the causal effects of specific components despite being resource intensive. Future studies with hybrid effectiveness-implementation and sequential designs, and more standardized reporting of intervention intensity and complexity could help stakeholders assess the return on investment of these interventions.

Psychosocial Factors and Glycemic Control in Young Adults With Youth-Onset Type 2 Diabetes

Importance

Youth-onset type 2 diabetes is associated with poor glycemic control and early onset of complications. Identification of psychosocial factors associated with poor glycemic control is needed to inform efficacious interventions.

Objective

To identify psychosocial factors associated with glycated hemoglobin (HbA1c) levels in young adults with youth-onset type 2 diabetes.

Design, Setting, and Participants

For the iCount cohort study, HbA1c levels were measured twice (at baseline [T1] and at 1 year [T2]) during the last years (2017-2019) of the observational phase of the multicenter Treatment Options for Type 2 Diabetes in Adolescents and Youth (TODAY2) study. Participants were young adults who had been diagnosed with type 2 diabetes during childhood or adolescence. Data were analyzed from December 2021 to September 2023.

Main Outcomes and Measures

Glycemic control was examined categorically (high [≥8.0%] vs low [<8.0%] HbA1c), continuously (HbA1c level), and over time (change in HbA1c: decreased ≥0.5%, remained stable, or increased ≥0.5%). Psychosocial measures included beliefs about medicines, depression and anxiety symptoms, diabetes distress, diabetes self-efficacy, self-management support, and unmet material needs. Multivariable logistic and linear regression models evaluated the association of each psychosocial factor with the probability of T2 HbA1c of 8.0% or greater, T2 HbA1c level, and change in HbA1c.

Results

Of the 411 TODAY2 participants approached, 381 enrolled in the iCount study, and 348 with T1 and T2 HbA1c data comprised the analysis group. The 348 participants had a mean (SD) age of 26.1 (2.5) years and a mean (SD) HbA1c of 9.4% (2.8%). Most participants (229 [65.8%]) were women. In adjusted multivariable regressions, greater beliefs that diabetes medicines are necessary (odds ratio [OR], 1.19 [95% CI, 1.03-1.37]; P = .02), concerns about medicines (OR, 1.20 [95% CI, 1.00-1.45]; P = .049), diabetes distress (OR, 1.08 [95% CI, 1.02-1.15]; P = .006), and high distress (OR, 2.18 [95% CI, 1.15-4.13]; P = .02) increased the odds of high HbA1c at T2. Greater support (OR, 0.67 [95% CI, 0.46-0.97]; P = .04) and diabetes self-efficacy (OR, 0.91 [95% CI, 0.84-0.99]; P = .02) decreased the odds of high HbA1c at T2. Diabetes distress was associated with higher HbA1c level at T2 (coefficient, 0.08 [95% CI, 0.02-0.13]; P = .01). Beliefs that diabetes medicines are necessary (OR, 1.20 [95% CI, 1.03-1.39]; P = .02) and concerns about medicines (OR, 1.22 [95% CI, 1.00-1.47]; P = .048) increased the odds of an HbA1c decrease of at least 0.5% over 1 year.

Conclusions and Relevance

In this cohort study of young adults with youth-onset type 2 diabetes, beliefs about medicines, high diabetes distress, low diabetes self-efficacy, and self-management support were associated with high HbA1c over time. Future research should assess whether interventions that address these factors result in improved glycemic control in this at-risk group.

Food Insecurity Prevalence and Risk Factors at a Large Academic Medical Center in Michigan

Importance

Health care systems are increasingly adopting methods to screen for and integrate food insecurity and other social risk factors into electronic health records. However, there remain knowledge gaps regarding the cumulative burden of food insecurity in large clinical settings, which patients are most at risk, and the extent to which patients are interested in social assistance through their health care system.

Objective

To evaluate the 5-year prevalence and associated risk factors of food insecurity among adult primary care patients, and to examine factors associated with patients' interest in social assistance among those with food insecurity.

Design, Setting, and Participants

This cross-sectional analysis of a retrospective cohort study took place at a tertiary care academic medical center (encompassing 20 primary care clinics) in Michigan. Participants included adult patients who completed screening for social risk factors between August 1, 2017, and August 1, 2022. Data analysis was performed from November 2022 to June 2023.

Exposure

Food insecurity was assessed using the Hunger Vital Sign.

Main Outcomes and Measures

The primary outcome was patients' interest in social assistance, and associated factors were examined using multivariate logistic regression models, adjusting for patients' demographic and health characteristics.

Results

Over the 5-year period, 106 087 adult primary care patients (mean [SD] age, 52.9 [17.9] years; 61 343 women [57.8%]) completed the standardized social risk factors questionnaire and were included in the analysis. The overall prevalence of food insecurity was 4.2% (4498 patients), with monthly trends ranging from 1.5% (70 positive screens) in August 2018 to 5.0% (193 positive screens) in June 2022. Food insecurity was significantly higher among patients who were younger, female, non-Hispanic Black or Hispanic, unmarried or unpartnered, and with public health insurance. Food insecurity was significantly associated with a higher cumulative burden of social needs, including social isolation, medical care insecurity, medication nonadherence, housing instability, and lack of transportation. Only 20.6% of patients with food insecurity (927 patients) expressed interest in social assistance. Factors associated with interest in social assistance including being non-Hispanic Black, unmarried or unpartnered, a current smoker, and having a higher burden of other social needs.

Conclusions and Relevance

In this retrospective cohort study, the overall prevalence of food insecurity was 4.2%, of whom approximately 1 in 5 patients with food insecurity expressed interest in assistance. This study highlights ongoing challenges in ensuring all patients complete routine social determinants of health screening and gaps in patients' interest in assistance for food insecurity and other social needs through their health care system.

Trends and Predictors of Glycemic Control Among Adults With Type 2 Diabetes Covered by Alabama Medicaid, 2011-2019

INTRODUCTION

Despite advances in diabetes management, only one-quarter of people with diabetes in the US achieve optimal targets for glycated hemoglobin A1c (HbA1c), blood pressure, and cholesterol. We sought to evaluate temporal trends and predictors of achieving glycemic control among adults with type 2 diabetes covered by Alabama Medicaid from 2011 through 2019.

METHODS

We completed a retrospective analysis of Medicaid claims and laboratory data, using person-years as the unit of analysis. Inclusion criteria were being aged 19 to 64 years, having a diabetes diagnosis, being continuously enrolled in Medicaid for a calendar year and preceding 12 months, and having at least 1 HbA1c result during the study year. Primary outcomes were HbA1c thresholds of <7% and <8%. Primary exposure was study year. We conducted separate multivariable-adjusted logistic regressions to evaluate relationships between study year and HbA1c thresholds.

RESULTS

We included 43,997 person-year observations. Mean (SD) age was 51.0 (9.9) years; 69.4% were women; 48.1% were Black, 42.9% White, and 0.4% Hispanic. Overall, 49.1% had an HbA1c level of <7% and 64.6% <8%. Later study years and poverty-based eligibility were associated with lower probability of reaching target HbA1c levels of <7% or <8%. Sex, race, ethnicity, and geography were not associated with likelihood of reaching HbA1c <7% or <8% in any model.

CONCLUSION

Later study years were associated with lower likelihood of meeting target HbA1c levels compared with 2011, after adjusting for covariates. With approximately 35% not meeting an HbA1c target of <8%, more work is needed to improve outcomes of low-income adults with type 2 diabetes.

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 Adequacy of Dietary Intake in Youth and Young Adults With Youth-Onset Type 1 and Type 2 Diabetes

BACKGROUND

Household food insecurity is associated with poor dietary intake in the general population, but little is known about this association in persons with diabetes.

OBJECTIVE

We examined the degree of adherence to the dietary reference intakes and 2020-2025 Dietary Guidelines for Americans overall and according to food security status and diabetes type among youth and young adults (YYA) with youth-onset diabetes.

DESIGN, PARTICIPANTS, AND SETTING

The SEARCH for Diabetes in Youth study includes 1,197 YYA with type 1 diabetes (mean age = 21 ± 5 years) and 319 YYA with type 2 diabetes (25 ± 4 years). Participants (or parents if younger than age 18 years) completed the US Department of Agriculture Household Food Security Survey Module, wherein ≥3 affirmations indicate food insecurity.

MAIN OUTCOME MEASURES

Diet was assessed via food frequency questionnaire and compared with age- and sex-specific dietary reference intakes for 10 nutrients and dietary components (calcium; fiber; magnesium; potassium; sodium; vitamins C, D, and E; added sugar; and saturated fat).

STATISTICAL ANALYSES PERFORMED

Median regression models controlled for sex- and type-specific means for age, diabetes duration, and daily energy intake.

RESULTS

Prevalence of guideline adherence was overarchingly poor, with <40% of participants meeting recommendations for eight of 10 nutrients and dietary components; however, higher adherence (>47%) was observed for vitamin C and added sugars. YYA with type 1 diabetes who were food insecure were more likely to meet recommendations for calcium, magnesium, and vitamin E (P < 0.05), and less likely for sodium (P < 0.05) than those with food security. In adjusted models, YYA with type 1 diabetes who were food secure had closer median adherence to sodium (P = 0.002) and fiber (P = 0.042) guidelines than those food insecure. No associations were observed in YYA with type 2 diabetes.

CONCLUSIONS

Food insecurity is associated with lesser adherence to fiber and sodium guidelines in YYA with type 1 diabetes, which may lead to diabetes complications and other chronic diseases.

The National Clinical Care Commission Report to Congress: Leveraging Federal Policies and Programs for Population-Level Diabetes Prevention and Control: Recommendations From the National Clinical Care Commission

The etiology of type 2 diabetes is rooted in a myriad of factors and exposures at individual, community, and societal levels, many of which also affect the control of type 1 and type 2 diabetes. Not only do such factors impact risk and treatment at the time of diagnosis but they also can accumulate biologically from preconception, in utero, and across the life course. These factors include inadequate nutritional quality, poor access to physical activity resources, chronic stress (e.g., adverse childhood experiences, racism, and poverty), and exposures to environmental toxins. The National Clinical Care Commission (NCCC) concluded that the diabetes epidemic cannot be treated solely as a biomedical problem but must also be treated as a societal problem that requires an all-of-government approach. The NCCC determined that it is critical to design, leverage, and coordinate federal policies and programs to foster social and environmental conditions that facilitate the prevention and treatment of diabetes. This article reviews the rationale, scientific evidence base, and content of the NCCC's population-wide recommendations that address food systems; consumption of water over sugar-sweetened beverages; food and beverage labeling; marketing and advertising; workplace, ambient, and built environments; and research. Recommendations relate to specific federal policies, programs, agencies, and departments, including the U.S. Department of Agriculture, the Food and Drug Administration, the Federal Trade Commission, the Department of Housing and Urban Development, the Environmental Protection Agency, and others. These population-level recommendations are transformative. By recommending health-in-all-policies and an equity-based approach to governance, the NCCC Report to Congress has the potential to contribute to meaningful change across the diabetes continuum and beyond. Adopting these recommendations could significantly reduce diabetes incidence, complications, costs, and inequities. Substantial political resolve will be needed to translate recommendations into policy. Engagement by diverse members of the diabetes stakeholder community will be critical to such efforts.

Within-person Relationships of Sleep Duration with Next-Day Stress and Affect in the Daily Life of Adults with Type-1 Diabetes

Objective

The objective of this study is to examine the within-person relationships between sleep duration and next-day stress and affect in the daily life of individuals with T1D.

Methods

Study participants were recruited in the Function and Emotion in Everyday Life with Type 1 Diabetes (FEEL-T1D) study. Sleep duration was derived by synthesizing objective (actigraphy) and self-report measures. General and diabetes-specific stress and positive and negative affect were measured using ecological momentary assessment. Multilevel regression was used to examine the within-person relationships between sleep duration and next-day stress and affect. Cross-level interactions were used to explore whether gender and baseline depression and anxiety moderated these within-person relationships.

Results

Adults with T1D (n=166) completed measurements for 14 days. The average age was 40.99 years, and 91 participants (54.82%) were female. The average sleep duration was 7.29 hours (SD=1.18 hours). Longer sleep was significantly associated with lower general stress (p<0.001) but not diabetes-specific stress (p=0.18) on the next day. There were significant within-person associations of longer sleep with lower levels on next-day negative affect (overall, p=0.002, disappoint, p=0.05; sad, p=0.05; tense, p<0.001; upset, p=0.008; anxious, p=0.04). There were no significant associations with positive affect. Examination of the interaction effects did not reveal significant differential relationships for men and women and for individuals with and without depression or anxiety at baseline.

Conclusion

Findings from this study suggest optimizing sleep duration as an important interventional target for better managing general stress and improving daily emotional wellbeing of individuals with T1D.

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.

Multiple social risk factors are adversely associated with diabetes management and psychosocial outcomes among adults with diabetes

Adults from structurally marginalized populations have disproportionately higher rates of diabetes, highlighting the importance of addressing social risk factors in diabetes prevention and management. This study examined the correlations among multiple social risk factors and their respective burden on diabetes management and psychosocial health outcomes among adults with diabetes. Data came from the baseline assessment of an ongoing randomized controlled trial evaluating approaches to addressing unmet social needs among 579 adults with diabetes. Four social risks (food insecurity, financial insecurity, housing insecurity, and utility insecurity) were assessed, dichotomized and summed to create a score of cumulative social risk factors. The outcomes of interest were: hemoglobin A1c, cost-related non-adherence for diabetes, diabetes distress, and anxiety or depression. Multivariate regression models were used to examine the associations between cumulative social risk factors and health outcomes, adjusting for sociodemographic characteristics and diabetes duration. Approximately 18% of study participants reported one social risk, 18% reported two social risks, and 23% reported three or four social risks. After multivariate adjustment, adults with three or four social risk factors had a greater likelihood of cost-related non-adherence (OR 2.81, 95% CI 1.95, 4.06), diabetes distress (OR 3.03, 95% CI 2.13, 4.31), and anxiety or depression (OR 5.36, 95% CI 3.39, 8.47), compared to adults with no social risk factors. Significant dose-response relationships were observed with greater social risk factors and poorer diabetes-related outcomes. These findings support efforts to address systemic contributors to diabetes management and care to better promote individual and population health.

Bridge to Health/Puente a la Salud: a pilot randomized trial to address diabetes self-management and social needs among high-risk patients

Social needs contribute to persistent diabetes disparities; thus, it is imperative to address social needs to optimize diabetes management. The purpose of this study was to determine determine the feasibility and acceptability of health system-based social care versus social care + behavioral intervention to address social needs and improve diabetes self-management among patients with type 2 diabetes. Black/African American, Hispanic/Latino, and low-income White patients with recent hemoglobin A1C (A1C) ≥ 8%, and ≥1 social need were recruited from an integrated health system. Patients were randomized to one-of-two 6-month interventions: (a) navigation to resources (NAV) facilitated by a Patient Navigator; or (b) NAV + evidence-based nine-session diabetes self-management support (DSMS) program facilitated by a community health worker (CHW). A1C was extracted from the electronic health record. We successfully recruited 110 eligible patients (54 NAV; 56 NAV + DSMS). During the trial, 78% NAV and 80% NAV + DSMS participants successfully connected to a navigator; 84% NAV + DSMS connected to a CHW. At 6-month follow-up, 33% of NAV and 34% of NAV + DSMS participants had an A1C < 8%. Mean reduction in A1C was clinically significant in NAV (-0.65%) and NAV + DSMS (-0.72%). By follow-up, 89% of NAV and 87% of NAV + DSMS were successfully connected to resources to address at least one need. Findings suggest that it is feasible to implement a health system-based social care intervention, separately or in combination, with a behavioral intervention to improve diabetes management among a high-risk, socially complex patient population. A larger, pragmatic trial is needed to test the comparative effectiveness of each approach on diabetes-related outcomes.

Relationship between material needs security and clinical outcomes in adults with type 2 diabetes in Lebanon

BACKGROUND

Despite their documented significance in type 2 diabetes (T2DM) management, social determinants of health (SDOHs) including material needs security are poorly studied in the Middle East and North Africa (MENA) region. This study aims to assess the relation between material needs security and clinical outcomes in Lebanese adults with T2DM.

METHODS

Subjects with T2DM (n = 300) were recruited; demographic and material need variables were collected using self-reported questionnaires. Measured clinical outcomes included Hemoglobin A1c (A1C), systolic (SBP) and diastolic blood pressure (DBP). Regression models were used to examine associations between material needs security and clinical outcomes, controlling for relevant confounding variables.

RESULTS

Most of the participants were men, married and with lower education levels. Having higher material needs security and being employed predicted better A1C levels (p < 0.05), whereas male sex was associated with poorer A1C(β = 0.52, p = 0.03) and DBP(β = 3.06, p = 0.05). Other predictors of DBP included older age and lack of confidence in filling out medical forms, reflecting lower health literacy.

CONCLUSIONS

Our study highlights the importance of material needs in achieving optimal T2DM outcomes T2DM in the MENA region. Further research is needed to understand potential pathways/mechanisms and options for effective interventions.

Relationships between enabling services use and access to care among adults with cardiometabolic risk factors: findings from the 2014 National Health Center Patient Survey

BACKGROUND

Community health centers (CHCs) provide comprehensive primary and preventive care to medically underserved, low-income, and racially/ethnically diverse populations. CHCs also offer enabling services, non-clinical assistance to reduce barriers to healthcare due to unmet social and material needs, to improve access to healthcare and reduce health disparities. For patients with modifiable cardiometabolic risk factors, including obesity, hypertension, and diabetes, enabling services may provide additional support to improve disease management. However, little is known about the relationship between enabling services and healthcare accessibility and utilization among patients with cardiometabolic risk factors.

METHODS

This study uses data from the 2014 Health Center Patient Survey to examine the relationship between enabling services use and delayed/foregone care, routine check-ups, and emergency room visits, among adult community health center patients in the United States with cardiometabolic risk factors (N = 2358). Outcomes of enabling services users were compared to nonusers using doubly robust propensity score matching methods and generalized linear regression models.

RESULTS

Overall, enabling service users were 15.4 percentage points less likely to report delayed/foregone care and 29.4 percentage points more likely to report routine check-ups than nonusers. Enabling service users who lived in urban areas, younger and middle-aged adults, and those with two cardiometabolic risk factors were also less likely to report delayed/foregone care and/or more likely to report routine check-ups in comparison with nonusers. However, among adults with three or more cardiometabolic risk factors, enabling services use was associated with a 41.3 percentage point increase in emergency room visits and a 7.6 percentage point decrease in routine check-ups.

CONCLUSIONS

The findings highlight the value in utilizing enabling services to improve timeliness and receipt of care among CHC patients with heightened cardiometabolic risk. There is a need for targeting high-risk populations with additional enabling services to support management of multiple chronic conditions.

Healthy food prescription incentive programme for adults with type 2 diabetes who are experiencing food insecurity: protocol for a randomised controlled trial, modelling and implementation studies

INTRODUCTION

The high cost of many healthy foods poses a challenge to maintaining optimal blood glucose levels for adults with type 2 diabetes mellitus who are experiencing food insecurity, leading to diabetes complications and excess acute care usage and costs. Healthy food prescription programmes may reduce food insecurity and support patients to improve their diet quality, prevent diabetes complications and avoid acute care use. We will use a type 2 hybrid-effectiveness design to examine the reach, effectiveness, adoption, implementation and maintenance (RE-AIM) of a healthy food prescription incentive programme for adults experiencing food insecurity and persistent hyperglycaemia. A randomised controlled trial (RCT) will investigate programme effectiveness via impact on glycosylated haemoglobin (primary outcome), food insecurity, diet quality and other clinical and patient-reported outcomes. A modelling study will estimate longer-term programme effectiveness in reducing diabetes-related complications, resource use and costs. An implementation study will examine all RE-AIM domains to understand determinants of effective implementation and reasons behind programme successes and failures.

METHODS AND ANALYSIS

594 adults who are experiencing food insecurity and persistent hyperglycaemia will be randomised to a healthy food prescription incentive (n=297) or a healthy food prescription comparison group (n=297). Both groups will receive a healthy food prescription. The incentive group will additionally receive a weekly incentive (CDN$10.50/household member) to purchase healthy foods in supermarkets for 6 months. Outcomes will be assessed at baseline and follow-up (6 months) in the RCT and analysed using mixed-effects regression. Longer-term outcomes will be modelled using the UK Prospective Diabetes Study outcomes simulation model-2. Implementation processes and outcomes will be continuously measured via quantitative and qualitative data.

ETHICS AND DISSEMINATION

Ethical approval was obtained from the University of Calgary and the University of Alberta. Findings will be disseminated through reports, lay summaries, policy briefs, academic publications and conference presentations.

Diabetes technologies for children and adolescents with type 1 diabetes are highly dependent on coverage and reimbursement: results from a worldwide survey

INTRODUCTION

To study healthcare professionals' (HCP) perceptions on decision making to start insulin pumps and continuous glucose monitoring (CGM) systems in pediatric type 1 diabetes.

RESEARCH DESIGN AND METHODS

An electronic survey supported by the International Society for Pediatric and Adolescent Diabetes (ISPAD) was disseminated through a weblink structured as follows: (1) HCP's sociodemographic and work profile; (2) perceptions about indications and contraindications for insulin pumps and (3) for CGM systems; and (4) decision making on six case scenarios.

RESULTS

247 responses from 49 countries were analyzed. Seventy per cent of respondents were members of ISPAD. Most of participants were women over 40 years old, who practice as pediatric endocrinologists for more than 10 years at university/academic centers and follow more than 500 people with type 1 diabetes. Although insulin pumps and CGMs are widely available and highly recommended among respondents, their uptake is influenced by access to healthcare coverage/insurance. Personal preference and cost of therapy were identified as the main reasons for turning down diabetes technologies. Parental educational level, language comprehension and income were the most relevant socioeconomic factors that would influence HCPs to recommend diabetes technologies, while gender, religious affiliation and race/ethnicity or citizenship were the least relevant.

CONCLUSIONS

Responders seem to be markedly supportive of starting people on diabetes technologies. However, coverage/insurance for devices holds the biggest impact on the extent of their recommendations.

Insights about interventions to address food insecurity in adults with type 2 diabetes: Valuable lessons from the stories of African Americans living in the inner city

OBJECTIVES

This qualitative study aimed to gain insight from the perspectives of food insecure African Americans living in an inner city regarding important diabetes intervention strategies and components.

METHODS

Using a grounded theory approach, two focus groups (totaling 16 individuals) were conducted in Milwaukee, Wisconsin. Purposive, convenience sampling was used to identify food insecure adults with diabetes. Questions were asked using a moderator guide to explore challenges and barriers to managing diabetes within the context of food insecurity, and facilitators or resources that helped participants improve diabetes management. Questions were open ended and followed by probes asking for additional perspectives and personal experiences related to the overarching topic, and questions asking to clarify statements.

RESULTS

Overarching concepts and themes specific to possible interventions discussed during the focus groups included group education, peer support, access to community resources and programs, stress management, and faith-based programs as desired intervention outcomes.

CONCLUSIONS

Key findings from the current study show that inner-city African Americans with diabetes desire interventions that foster social and community support systems.

PRACTICE IMPLICATIONS

Given this insight, more robust and comprehensive interventions are needed to account for the multifaceted experience of food insecurity and diabetes within the inner-city environment.

Evaluation of a Community Health Worker Social Prescribing Program Among UK Patients With Type 2 Diabetes

IMPORTANCE

Despite lacking robust evidence of effectiveness, health care systems in developed countries are funding holistic community health worker (CHW) social prescribing programs that address social needs and health behaviors as adjuncts to clinical care.

OBJECTIVE

To determine whether a UK National Health Service (NHS) CHW social prescribing program was associated with improved hemoglobin A1c (HbA1c) levels among patients with type 2 diabetes.

DESIGN, SETTING, AND PARTICIPANTS

This cohort study with difference-in-differences analysis was conducted among 8086 patients (4752 in the referral program, 3334 in the control group) in 24 NHS primary care practices in a city in North East England. Patients aged 40 to 74 years with a diagnosis of type 2 diabetes were observed for 8 years, from 2011 through 2019. The statistical analysis was conducted between June 1, 2019, and January 31, 2021.

INTERVENTIONS

A social prescribing program, launched in April 2015, enabling primary care staff to refer patients to CHW support to identify condition management and social needs goals and access voluntary and community sector support to address these goals. Intervention referral was only available in primary care practices in the city's west. The control group included patients in the city's east where referral was unavailable.

MAIN OUTCOMES AND MEASURES

HbA1c level, a marker of glycemic control.

RESULTS

A total of 8086 patients were included in the analysis (mean [SD] age, 57.8 [8.78] years; 3477 women [43%]; 6631 White patients [82%]). Mean (SD) baseline HbA1c levels were 7.56% (1.47%) in the referral program group and 7.44% (1.43%) in the control group. Following introduction of the social prescribing referral program, the referral group experienced an HbA1c reduction of -0.10 percentage points (95% CI, -0.17 to -0.03 percentage points) compared with the control group. The association increased over time: after 3 years the estimated association was -0.14 percentage points (95% CI, -0.24 to -0.03 percentage points). The association was stronger for White patients compared with non-White patients (-0.15 percentage points [95% CI, -0.26 to -0.04 percentage points] after 3 years), those with fewer additional comorbidities (-0.16 percentage points [95% CI, -0.29 to -0.04 percentage points] after 3 years), and those living in the most socioeconomically deprived areas (-0.19 percentage points [95% CI, -0.32 to -0.07 percentage points] after 3 years).

CONCLUSIONS AND RELEVANCE

In this study of UK adults with type 2 diabetes, a social prescribing program with referral to CHWs targeting patients' social needs and health behaviors was associated with improved HbA1c levels, suggesting that holistic CHW interventions may help to reduce the public health burden of type 2 diabetes.

A multi-scalar perspective on health and urban housing: an umbrella review

With more than half the world's population living in cities, understanding how the built environment impacts human health at different urban scales is crucial. To be able to shape cities for health, an understanding is needed of planetary health impacts, which encompass the human health impacts of human-caused disruptions on the Earth's natural ecosystems. This umbrella review maps health evidence across the spatial scales of the built environment (building; neighbourhood; and wider system, including city, regional and planetary levels), with a specific focus on urban housing. Systematic reviews published in English between January 2011 and December 2020 were searched across 20 databases, with 1176 articles identified and 124 articles screened for inclusion. Findings suggests that most evidence reports on health determinants at the neighbourhood level, such as greenspace, physical and socio-economic conditions, transport infrastructure and access to local services. Physical health outcomes are also primarily reported, with an emerging interest in mental health outcomes. There is little evidence on planetary health outcomes and significant gaps in the research literature are identified. Based on these findings, three potential directions are identified for future research.

Fatty liver index and progression to type 2 diabetes: a 5-year longitudinal study in Spanish workers with pre-diabetes

OBJECTIVE

The main aim of the study was to evaluate the association between non-alcoholic fatty liver disease (NAFLD), estimated by fatty liver index (FLI), and the development of type 2 diabetes (T2D) in a large cohort of adult workers with pre-diabetes.

DESIGN

Prospective cohort study.

SETTING

Occupational health services from Spain.

PARTICIPANTS

16 648 adult workers (aged 20-65 years) with pre-diabetes (fasting plasma glucose (FPG) of 100-125 mg/dL).

OUTCOME AND MEASURES

FLI was calculated based on measurements of triglycerides, body mass index, waist circumference and γ-glutamyltransferase. The population was classified into three categories: FLI<30 (no hepatic steatosis), FLI 30-60 (intermediate status) and FLI>60 (hepatic steatosis). Sociodemographic, anthropometric, dietary habits, physical activity and clinical data were collected from all subjects. The incidence rate of T2D was determined after 5 years of follow-up.

RESULTS

After 5 years of follow-up, 3706 of the 16 648 participants (22.2%) were diagnosed with T2D, corresponding to an annual rate of progression of 4.5%. FLI was strongly associated with T2D conversion. The incidence rates of T2D in the FLI<30, FLI 30-60 and FLI>60 groups were significantly different after 5 years of follow-up were 19/6,421 (0.3%), 338/4,318 (7.8%) and 3,349/5,909 (56.7%), respectively. This association remained significant for FLI>60 after adjustment for, age, diet, physical activity, FPG, blood pressure, social class and smoking habits (adjusted HR=6.879; 95% CI 5.873 to 8.057 for men, and HR=5.806; 95% CI 4.863 to 6.932 for women).

CONCLUSION

NAFLD assessed by FLI independently predicted the risk of conversion to T2D among people with pre-diabetes. FLI may be an easily determined and valuable early predictor for T2D in people with pre-diabetes. FLI-based assessment of NAFLD in subjects with pre-diabetes in routine clinical practice could allow the adoption of effective measures to prevent and reduce their progression to T2D.

Financial burden, distress, and toxicity in cardiovascular disease

Cardiovascular disease (CVD) is a major source of financial burden and distress, which has 3 main domains: (1) psychological distress; (2) cost-related care non-adherence or medical care deferral, and (3) tradeoffs with basic non-medical needs. We propose 4 ways to reduce financial distress in CVD: (1) policymakers can expand insurance coverage and curtail underinsurance; (2) health systems can limit expenditure on low-benefit, high-cost treatments while developing services for high-risk individuals; (3) physicians can engage in shared-decision-making for high-cost interventions, and (4) community-based initiatives can support patients with system navigation and financial coping. Avenues for research include (1) analysis of how healthcare policies affect financial burden; (2) comparative effectiveness studies examining high and low-cost strategies for CVD management; and (3) studying interventions to reduce financial burden, financial coaching, and community health worker integration.

ACTonDiabetes-a guided psychological internet intervention based on Acceptance and Commitment Therapy (ACT) for adults living with type 1 or 2 diabetes: results of a randomised controlled feasibility trial

OBJECTIVES

This two-group randomised controlled trial evaluates the feasibility of an Acceptance and Commitment Therapy (ACT)-based internet intervention for diabetes distress in people with diabetes type 1 or type 2. Participants were assigned to a guided self-help intervention (EG) or waitlist control group (CG).

SETTING

Recruitment took place following an open recruitment strategy including different diabetes centres, self-help groups and social media platforms.

PARTICIPANTS

Eligibility criteria comprised being 18 years of age or older, self-reported diagnosis of type 1 or type 2 diabetes, internet access, sufficient German language skills and written informed consent.

INTERVENTION

ACTonDiabetes is an internet-based and mobile-based intervention and comprises an introduction and seven modules (one module per week, processing time about 45-60 min). Intervention contents are based on ACT.

PRIMARY AND SECONDARY OUTCOME MEASURES

Participants were assessed before and 8 weeks after randomisation. Primary outcome was feasibility (trial recruitment, acceptability). Potential group differences in diabetes distress and other outcomes at follow-up were analysed using linear regression models with baseline values as predictors. All analyses were based on an intention-to-treat principle, potential negative effects were analysed on per-protocol basis.

RESULTS

From October 2017 to April 2018, N=42 people with diabetes consented and were randomised (EG n=21, CG n=21). Forty-three per cent of the EG completed all treatment modules within 8 weeks. Across modules, formative user feedback revealed that contents could be optimised regarding comprehensibility (34%), individualisation (20%) and text amount (21%). Overall, 57% of participants dropped out prior to full treatment completion. There were reductions of diabetes distress in the EG (d=0.65, p=0.042).

CONCLUSIONS

Modifications of the intervention content according to the user feedback will be performed to further improve acceptability. Mechanisms to foster intervention adherence should be considered for lowering the attrition rate. ACTonDiabetes is feasible for the implementation in a confirmatory trial.

Bridge to Health/ Puente a la Salud: Rationale and design of a pilot feasibility randomized trial to address diabetes self-management and unmet basic needs among racial/ethnic minority and low-income patients

Introduction

Racial/ethnic and socioeconomic disparities in diabetes prevalence and management persist. Unmet basic needs such as food insecurity and unstable housing interfere with optimal diabetes self-management. Bridge to Health/Puente a la Salud is a randomized pilot trial designed to examine the feasibility of testing the effectiveness of addressing unmet basic needs via navigation services versus navigation plus diabetes self-management support (DSMS) on improving diabetes-related outcomes among racial/ethnic minority and low-income patients with uncontrolled diabetes.

Material and methods

We recruited and randomized 110 African American, Hispanic, and Medicaid patients (any race/ethnicity) with diabetes and recent hemoglobin A1C ≥ 8% to one of two 6-month interventions: 1) Navigation only; or 2) Navigation + DSMS. In both arms, practice-embedded patient navigators help participants navigate social services and community-based resources to address unmet basic needs. In Navigation + DSMS, participants are also assigned to a community health worker (CHW) embedded in a local community-based organization who provides additional navigation support and delivers DSMS. A1C and unmet basic needs data are collected via routine lab and survey, respectively, at baseline and 6-month follow-up. Qualitative interviews with participants, health system leaders, CHWs, and patient navigators are conducted to explore intervention acceptability and determinants of implementation in a health care setting.

Discussion

Findings from this pilot feasibility study will enhance understanding about acceptability, preliminary clinical effectiveness, and facilitators and barriers to implementation of the Navigation only and Navigation + DSMS interventions and inform refinements of the overall study design for the larger, randomized clinical trial.

Lowering the impact of food insecurity in African American adults with type 2 diabetes mellitus (LIFT-DM) - Study protocol for a randomized controlled trial

BACKGROUND

There is strong evidence that disparities in the burden of diabetes exist by both race and poverty. Food insecurity, or an inability to or limitation in accessing nutritionally adequate food, is an important modifiable social determinant of health, particularly in adults with chronic disease. African Americans are more likely to be diagnosed with diabetes and more likely than whites to be food insecure.

METHODS

We describe a 4-year ongoing randomized controlled trial, which will test the separate and combined efficacy of monthly food vouchers and monthly food stock boxes layered upon diabetes education in improving glycemic control in low income, food insecure, African Americans with type 2 diabetes mellitus using a 2 × 2 factorial design. Three hundred African American adults with clinical diagnosis of diabetes and HbA1c ≥ 8% will be randomized into one of four groups: 1) diabetes education alone; 2) diabetes education plus food vouchers; 3) diabetes education plus stock boxes; and 4) diabetes education plus combined food vouchers and stock boxes. Our primary hypothesis is: among low-income, food insecure, African Americans with type 2 diabetes, those receiving diabetes education enhanced with food supplementation (food vouchers alone, stock boxes alone, or combination) will have significantly greater reduction in HbA1c at 12 months compared to those receiving diabetes education only.

DISCUSSION

Results from this study will yield valuable insight currently lacking on how best to design and deliver diabetes interventions to low-income, food insecure, African Americans with diabetes that takes into account both clinical and social determinants of health.

Moving Diabetes Upstream: the Social Determinants of Diabetes Management and Control Among Immigrants in the US

PURPOSE OF REVIEW

Relative to the US-born population, immigrants are less likely to successfully manage and control their diabetes, leading to a host of diabetes-related complications. This review draws on the social determinants of health framework (SDoH) to summarize the multilevel factors that shape diabetes care and management among immigrants in the USA.

RECENT FINDINGS

While the diabetes literature is replete with research on individual-level risk factors and health behaviors, empirical literature linking the SDoH to diabetes management among immigrants is limited. However, housing precarity, food insecurity, poverty, uninsurance and underinsurance, and limited support for immigrants in healthcare systems are consistently shown to deter diabetes management and care. Immigrants with diabetes face a multitude of structural constraints to managing their diabetes. More research that theorizes the role of SDoH in diabetes management along with empirical qualitative and quantitative studies are needed. Interventions to address diabetes also require a more upstream approach in order to mitigate the drivers of diabetes disparities among immigrants.

Asylum seekers' and Refugees' Changing Health (ARCH) study protocol: an observational study in Lebanon and Denmark to assess health implications of long-distance migration on communicable and non-communicable diseases and mental health

INTRODUCTION

By end of 2018, the European Union countries hosted approximately 2.5 million refugees and Lebanon alone hosted more than 1 million. The majority of refugees worldwide came from Syria. The prevailing study design in published studies on asylum seekers' and refugees' health leaves a number of fundamental research questions unanswerable. In the Asylum seekers' and Refugees' Changing Health (ARCH) study, we examine the health of a homogeneous group of refugees and asylum seekers in two very different host countries with very different migration histories. We aim to study the health impact of the migration process, living conditions, access to healthcare, gene-environment interactions and the health transition.

METHODS AND ANALYSIS

ARCH is an international multisite study of the health of adult (>18 years old) Syrian refugees and asylum seekers in Lebanon and Denmark. Using a standardised framework, we collect information on mental and physical health using validated scales and biological samples. We aim to include 220 participants in Danish asylum centres and 1100 participants in Lebanese refugee camps and settlements. We will use propensity score weights to control for confounding and multiple imputation to handle missing data.

ETHICS AND DISSEMINATION

Ethical approval has been obtained in Lebanon and Denmark. In the short term, we will present the cross-sectional association between long-distance migration and the results of the throat and wound swab, blood and faeces samples and mental health screenings. In the longer term, we are planning to follow the refugees in Denmark with collection of dried blood spots, mental health screenings and semistructured qualitative interviews on the participant's health and access to healthcare in the time lived in Denmark. Here, we present an overview of the background for the ARCH study as well as a thorough description of the methodology.

Differential Impact of Food Insecurity, Distress, and Stress on Self-care Behaviors and Glycemic Control Using Path Analysis

BACKGROUND

The aim of this study was to investigate the direct and indirect pathways through which food insecurity influences glycemic control and self-care behaviors.

METHODS

Using data collected from 615 adults with type 2 diabetes, we investigated pathways between food insecurity and diabetes outcomes using path analysis. We included measures of perceived stress, diabetes distress, diabetes fatalism, and depression as psychosocial factors in the pathway. Self-care behaviors included general diet, specific diet, exercise, blood sugar testing, foot care, and medication adherence. Analyses were conducted using Stata v14, to include both direct and indirect effects, with standardized estimates to allow comparison of paths.

RESULTS

Food insecurity was directly associated with stress (r = 0.43, p < 0.001), depression (r = 0.34, p < 0.001), fatalism (r = 0.09, p = 0.03), and distress (r = 0.36, p < 0.001). The type of stress, however, was differentially associated with outcomes, with distress associated with HbA1c (r = 0.25, p < 0.001), general and specific diet (r = - 0.28 and - 0.17, respectively, p = 0.001), and medication adherence (r = - 0.26, p < 0.001), while stress was associated with specific diet (r = - 0.14, p = 0.005) and medication adherence (r = - 0.15, p < 0.001) and depression was associated with exercise (r = - 0.06, p = 0.007). Food insecurity was indirectly associated with HbA1c (r = 0.08, p = 0.001), and four self-care behaviors (general diet, specific diet, exercise, and medication adherence).

CONCLUSIONS

Food insecurity influences self-care behaviors indirectly via multiple psychosocial factors, and glycemic control indirectly through diabetes distress, supporting the hypothesis that stress is an important mechanism. Programs to improve access to resources and manage psychosocial concerns should be combined with food-based programs for food insecure populations with diabetes.

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.

Food Insecurity Screening Among Families of Children With Diabetes

Little is known about screening in clinical settings for food insecurity (FI) among households of children with diabetes. This study evaluated the acceptability and feasibility of an FI screening initiative in a pediatric diabetes clinic that was implemented to help diabetes dietitian educators tailor management plans for families of children with type 1 or type 2 diabetes facing FI. The initiative comprised three validated screening questions, a care algorithm, a community resource handout, and a poster. In total, 50 families of children and adolescents aged 0-18 years with type 1 or type 2 diabetes were screened for FI. In-person semi-structured interviews combining open-ended and Likert-scale questions were conducted with 37 of the screened families and the three diabetes dietitian educators who conducted the screening. Perceived barriers and facilitators of the screening initiative were identified using content analysis, and Likert-scale questionnaires rated interviewees' comfort level with the screening questions. A reflective journal kept by an onsite research interviewer also facilitated the data interpretation process. Most families felt comfortable answering the screening questions. Families with FI appreciated the opportunity to express their concerns and learn about affordable food resources. However, ∼20% of these families described stigma and fear of judgment by clinicians if they screened positive for FI. Diabetes educators also felt comfortable with the screening questions but reported lack of time to screen all families and to follow-up with resources after a positive screen. A self-reported intake form was recommended to ensure that everyone is systematically screened. A standardized and respectful method of assessing FI could help clinicians better tailor treatment plans and support for families of children with diabetes who face FI. Based on these findings, similar FI screening initiatives should be implemented in other clinical settings as part of routine clinical practice.

Study protocol for a Community Health Worker (CHW)-led comprehensive neighborhood-focused program for medicaid enrollees in detroit

Residents of low income neighborhoods disproportionately experience poor health, and many have unmet social needs. Clinical trials have shown the efficacy of Community Health Worker (CHW) programs in improving outcomes for a variety of health conditions. An important next step is developing and evaluating financially sustainable CHW program models in real-life settings. This program evaluation examines health care utilization among participants in a geographically targeted program led by salaried CHWs from three Medicaid health plans. Beneficiaries who reside in the Cody Rouge neighborhood of Detroit and had more than 3 Emergency Department (ED) visits or at least 1 ambulatory care-sensitive hospitalization in the prior 12 months are eligible for the program. Health plan CHWs assigned to the program reach out to eligible beneficiaries to provide an assessment; link them to resources; and provide follow-up. At 12-month follow up, claims data on ED visits, ambulatory care-sensitive hospitalizations, primary care visits, and related costs will be compared between beneficiaries who participated and eligible beneficiaries randomized to receive usual outreach. We hypothesize that patients enrolled in the CHW intervention will experience a reduction in acute care usage resulting in cost savings compared to those receiving usual health plan outreach. This study is among the first to evaluate the impact on health care utilization of augmented services delivered by health plan CHWs for high-utilizing health plan members as part of a health plan-community-academic partnership. This study will provide important information on CHW program sustainability and provide insights into effective implementation of such programs.

Inflammation and Stress Biomarkers Mediate the Association between Household Food Insecurity and Insulin Resistance among Latinos with Type 2 Diabetes

BACKGROUND

Household food insecurity (HFI) is a stressor that is associated with type 2 diabetes (T2D). However, little is known about HFI and the insulin resistance (IR) underlying T2D, and the mechanisms involved.

OBJECTIVE

We examined the cross-sectional association between HFI and IR among low-income Latinos with T2D and tested whether inflammation and stress hormones mediated this association.

METHODS

HFI was measured with the 6-item US Household Food Security Survey module. IR was calculated from fasting plasma blood glucose and serum insulin. Inflammation was indicated by high-sensitivity C-reactive protein (hsCRP), and stress hormones included urinary cortisol, metanephrine, and normetanephrine. To test for an indirect effect of HFI on homeostasis model assessment of IR, a parallel multiple mediation model was run with biological markers that significantly differed between food security status-entered as mediators in the model. We used 95% bias-corrected bootstrap CIs, with 10,000 bootstrap samples, to assess the significance of the indirect effects.

RESULTS

The 121 participants with T2D were primarily Puerto Rican (85.8%), aged mean = 60.7 y, and 74% were female. Eighty-two (68%) were classified as food insecure. Compared with food-secure individuals, food-insecure individuals had a significantly higher IR [mean difference (Δ) = 7.21, P = 0.001], insulin (Δ = 9.7, P = 0.019), glucose (Δ = 41, P < 0.001), hsCRP (Δ = 0.8, P = 0.008), cortisol (Δ = 21, P = 0.045), and total cholesterol (Δ = 29, P = 0.004). Groups did not differ on other lipids, metanephrine, normetanephrine, or A1c. The mediation model showed a significant direct effect of HFI on hsCRP (P = 0.020) and on cortisol (P = 0.011). There was a direct effect of cortisol (P = 0.013), hsCRP (P = 0.044), and HFI on IR (P = 0.015). The total combined indirect effect of HFI through cortisol and hsCRP indicated partial mediation.

CONCLUSIONS

Among Latinos with T2D, HFI is associated with IR partially through inflammation and stress hormones. Interventions to ameliorate HFI and mitigate its effects on inflammation, stress, and IR are warranted. This trial was registered at clinicaltrials.gov as NCT01578096.

Conformity of Diabetes Mobile apps with the Chronic Care Model

Background

Despite the growing use of mobile applications (apps) for chronic disease management, the evidence on the effectiveness of this technology on clinical and behavioural outcomes of the patients is scant. Many studies highlight the importance of the theoretical foundations of mobile-based interventions. One of the most widely accepted models for the management of chronic diseases, such as diabetes, is the Chronic Care Model (CCM). In this study, we investigated the conformity of the selected diabetes mobile apps with CCM.

Method

We searched online journal databases related to diabetes mobile apps to find common features. Then considering the components of the CCM as a reference model, features of some popular and top-ranking apps were compared with CCM.

Results

Among 23 studied apps, 34 per cent of them had medium conformity and 66 per cent of these apps were in weak conformity. The self-management support component is covered by 100 per cent of them. Ninety-five per cent of apps have covered the proactive follow-up component.

Conclusions

App conformance with CCM is generally weak. App developers are recommended to give greater consideration to established theoretical models in their design and implementation.

A Review of Housing and Food Intersections: Implications for Nurses and Nursing Research

Study Background

Quality, accessibility, and affordability of housing and food are public health and nursing concerns. Yet, intersections between housing and food security are relatively understudied.

Purpose

The purpose of this article is to examine the evidence describing the relationship between food security and housing interventions, and second, describing specific opportunities for targeted strategies for nursing practice and research.

Methods

Arksey and O’Malley’s scoping review method was followed to search housing and food security research. A database search identified 46 studies that were mapped onto a social ecological theory to understand the micro, meso, exo, and macro interventions.

Results

Three major recommendations were identified. Micro-system recommendations include primary care screening for low-income groups. Meso- and exo-system recommendations focus on creating partnerships in research and enhancing social housing. Lastly, macro-system recommendations focus on challenging housing affordability standards. The major gap in the literature is addressing healthy housing.

Conclusion

Broadening housing interventions to include comprehensive approaches to meeting individuals’ needs offers more than simply packaging two interventions together. There is a significant moment in nursing in which nurses are witness to a paradigmatic shift in the ways to approach housing and food security.

Assessing the relationship between food insecurity and mortality among U.S. adults

PURPOSE

Significant evidence supports a relationship between food insecurity and health, but little work has investigated its relationship on all-cause mortality within a high resource country, such as the United States.

METHODS

Data from the 2003-2010 National Health and Nutrition Examination Survey was matched to National Death Index information. Cox models were used to study the relationship between mortality and food insecurity, adjusting for relevant covariates in a sequential manner (demographics, comorbidities, lifestyle variables, body mass index). Food insecurity was used as dichotomous and as four categories.

RESULTS

Of 20,918 participants, 11.6% (representing 208,789,244 U.S. residents) were food insecure. When food insecurity was dichotomized, there was 49% higher odds of mortality after adjusting for demographics (HR, 1.49; 95% CI, 1.19-1.87). After adjusting for comorbidities, the HR remained significant, but lost significance with adjustment for lifestyle factors and body mass index (HR, 1.15; 95% CI, 0.94-1.42). However, marginal food security lost significance after adjustment for lifestyle variables.

CONCLUSIONS

Food insecurity significantly impacts all-cause mortality in the United States; however, lifestyle may explain this relationship. Interventions should account for level of severity when creating targeted programs.

The Next Generation of Diabetes Translation: A Path to Health Equity

Disparities in diabetes burden exist in large part because of the social determinants of health (SDOH). Translation research and practice addressing health equity in diabetes have generally focused on changing individual behavior or providing supportive approaches to compensate for, rather than directly target, SDOH. The purpose of this article is to propose a pathway for addressing SDOH as root causes of diabetes disparities and as an essential target for the next generation of interventions needed to achieve health equity in diabetes prevention and treatment. This review describes ( a) the current burden of diabetes disparities, ( b) the influence of SDOH on diabetes disparities, ( c) gaps in and implications of current translation research, and ( d) approaches to achieving health equity in the next generation of diabetes translation.

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

OBJECTIVE

Food insecurity is reported in approximately 28 % of individuals with diabetes in the USA and is associated with poor glycaemic and lipid control. The present study aimed to understand the direct and indirect pathways through which food insecurity impacts glycaemic control in individuals with diabetes.Design/Setting/SubjectsAdults (n 615) with type 2 diabetes completed validated questionnaires after recruitment from two primary care clinics. Structural equation modelling was used to investigate mechanisms through which food insecurity influences diabetes self-care behaviours and glycaemic control, including investigation into possible direct and indirect effects of perceived stress and social support.

RESULTS

The final model showed that higher food insecurity was directly significantly related to increased stress (r=0·14, P<0·001) and increased glycosylated Hb (r=0·66, P=0·03). Higher stress was significantly related to poorer self-care (r=-0·54, P<0·001) and lower social support (r=-0·41, P<0·001). There was no significant direct association between food insecurity and self-care, or between perceived stress and glycaemic control.

CONCLUSIONS

Food insecurity had both a direct effect on glycaemic control and an indirect effect on self-care through stress. The indirect pathway suggests that efforts to address stress may influence the ability of individuals to perform diabetes self-care behaviours. The direct effect on glycaemic control suggests that pathways independent of self-care behaviours may also be necessary to improve diabetes outcomes. Results from the study suggest a multipronged approach is necessary to address food insecurity in individuals with diabetes.

Clinician Experiences with Screening for Social Needs in Primary Care

BACKGROUND

Despite clear evidence demonstrating the influence of social determinants on health, whether and how clinicians should address these determinants remain unclear. We aimed to understand primary care clinicians' experiences of administering a social needs screening instrument.

METHODS

Using a prospective, observational design, we identified patients living in communities with lower education and income seen by 17 clinicians from 12 practices in northern Virginia. Before office visits, patients completed social needs surveys, which probed about their quality of life, education, housing, finances, substance use, transportation, social connections, physical activity, and food access. Clinicians then reviewed the completed surveys with patients. Concurrently, clinicians participated in a series of learning collaboratives to consider how to address social needs as part of care and completed diary entries about how knowing the patient's social needs influenced care after seeing each patient.

RESULTS

Out of a total of 123 patients, 106 (86%) reported a social need. Excluding physical activity, 71% reported a social need, although only 3% wanted help. Clinicians reported that knowing the patient had a social need changed care delivery in 23% of patients and helped improve interactions with and knowledge of the patient in 53%. Clinicians reported that assessing social needs is difficult and resource intensive and that there were insufficient resources to help patients with identified needs.

CONCLUSIONS

Clinicians reported that knowing patients' social needs changed what they did and improved communication for many patients. However, more evidence is needed regarding the benefit of social needs screening in primary care before widespread implementation.

Executive Function in Adolescents With Type 1 Diabetes: Relationship to Adherence, Glycemic Control, and Psychosocial Outcomes

Objective

Impairments in executive function (EF) skills have been observed in youth with type 1 diabetes (T1D), and these skills are critical for following the complex treatment regimen. This study examines parent reports of EF in relation to measures of adherence, glycemic control (A1c), and psychosocial outcomes (depression and quality of life) in adolescents with T1D. A total of 120 adolescents (aged 13-17 years, 52.5% female, 87.5% White) with T1D and their parents completed questionnaires. Glucometers were downloaded and A1c was obtained during clinical visits at the time of enrollment. The prevalence of clinically significant elevated scores on specific EF skills ranged from 11 to 18.6%. In multivariate analyses, parent-reported EF deficits were associated with poorer adherence and lower quality of life, explaining 13 and 12% of the variance, respectively. Adolescents with T1D exhibit specific EF deficits that may negatively impact their quality of life and their ability to engage in self-management activities.

Individualising Chronic Care Management by Analysing Patients' Needs - A Mixed Method Approach

Background

Modern health systems are increasingly faced with the challenge to provide effective, affordable and accessible health care for people with chronic conditions. As evidence on the specific unmet needs and their impact on health outcomes is limited, practical research is needed to tailor chronic care to individual needs of patients with diabetes. Qualitative approaches to describe professional and informal caregiving will support understanding the complexity of chronic care. Results are intended to provide practical recommendations to be used for systematic implementation of sustainable chronic care models.

Method

A mixed method study was conducted. A standardised survey (n = 92) of experts in chronic care using mail responses to open-ended questions was conducted to analyse existing chronic care programs focusing on effective, problematic and missing components. An expert workshop (n = 22) of professionals and scientists of a European funded research project MANAGE CARE was used to define a limited number of unmet needs and priorities of elderly patients with type 2 diabetes mellitus and comorbidities. This list was validated and ranked using a multilingual online survey (n = 650). Participants of the online survey included patients, health care professionals and other stakeholders from 56 countries.

Results

The survey indicated that current care models need to be improved in terms of financial support, case management and the consideration of social care. The expert workshop identified 150 patient needs which were summarised in 13 needs dimensions. The online survey of these pre-defined dimensions revealed that financial issues, education of both patients and professionals, availability of services as well as health promotion are the most important unmet needs for both patients and professionals.

Conclusion

The study uncovered competing demands which are not limited to medical conditions. The findings emphasise that future care models need to focus stronger on individual patient needs and promote their active involvement in co-design and implementation. Future research is needed to develop new chronic care models providing evidence-based and practical implications for the regional care setting.

Developing and Implementing a Food Insecurity Screening Initiative for Adult Patients Living With Type 2 Diabetes

OBJECTIVES

Routine food insecurity screening is recommended in diabetes care to inform more tailored interventions that better support diabetes self-management among food-insecure patients. This pilot study explored the acceptability and feasibility of a food insecurity screening initiative within a diabetes care setting in Toronto.

METHODS

A systematic literature review informed the development of a food insecurity screening initiative to help health-care providers tailor diabetes management plans and better support food-insecure patients with type 2 diabetes. Interviews with 10 patients and a focus group with 15 care providers elicited feedback on the relevance and acceptance of the food insecurity screening questions and a care algorithm. Subsequently, 5 care providers at 4 sites implemented the screening initiative over 2 weeks, screening 33 patients. After implementation, 7 patients and 5 care providers were interviewed to assess the acceptability and feasibility of the screening initiative.

RESULTS

Our findings demonstrate that patients are willing to share their experiences of food insecurity, despite the sensitivity of this topic. Screening elicited information about how patients cope with food insecurity and how this affects their ability to self-manage diabetes. Care providers found this information helpful in directing their care and support for patients.

CONCLUSIONS

Using a standardized, respectful method of assessing food insecurity can better equip health-care providers to support food-insecure patients with diabetes self-management. Further evaluation of this initiative is needed to determine how food insecurity screening can affect patients' self-management and related health outcomes.

Influence of Race, Ethnicity and Social Determinants of Health on Diabetes Outcomes

BACKGROUND

There is strong evidence that race, ethnicity and social determinants of health significantly influence outcomes for patients with diabetes. A better understanding of the mechanisms of these relationships or associations would improve development of cost-effective, culturally tailored programs for patients with diabetes.

METHODS

This article reviews the current state of the literature on the influence of race and ethnicity and social determinants of health on process of care, quality of care and outcomes for diabetes, with particular emphasis on the rural South to give an overview of the state of the literature.

RESULTS

The literature review shows that racial or ethnic differences in the clinical outcomes for diabetes, including glycemic, blood pressure (BP) and lipid control, continue to persist. In addition, the literature review shows that the role of social determinants of health on outcomes, and the possible role these determinants play in disparities have largely been ignored. Psychosocial factors, such as self-efficacy, depression, social support and perceived stress, show consistent associations with self-care, quality of life and glycemic control. Neighborhood factors, such as food insecurity, social cohesion and neighborhood esthetics have been associated with glycemic control. Perceived discrimination has also been associated with self-care and the psychological component of quality of life.

CONCLUSION

Healthcare professionals need to be skilled in assessing social determinants of health and taking them into consideration in clinical care. In addition, more research is needed to identify the separate and combined influence of race and ethnicity and social determinants of health on process of care, quality of care and outcomes in diabetes, especially in the South, where the burden of disease is particularly high.

Food Insecurity and Diabetes in Developed Societies

Food insecurity is an important issue in public health even in developed societies, particularly for vulnerable populations. Food insecurity refers to the uncertain or limited access to adequate and safe foods. Emerging evidence shows an association between food insecurity, type 2 diabetes risk factors, and management of type 1 and type 2 diabetes. A review of the current literature describing the association between food insecurity and diabetes reveals possible mechanisms and pathophysiologic pathways. There is less evidence for effective interventions, and much of the current literature is limited to cross-sectional studies. Future work should evaluate longitudinal associations and ways to help vulnerable patients with diabetes access adequate food for effective diabetes management.

Health Beliefs and Practices of African Immigrants in Canada

A purposive sample of 14 immigrants living in Ontario, Canada, participated in two focus groups. The researchers used semi-structured interviews to collect data and five themes emerged from the data: beliefs about diabetes were centered on diverse factors, preserving culture through food preferences and preparation, cultural practices to stay healthy, cultural practices determined number of servings of fruit and vegetables per day, and engaging in physical activity to stay healthy. Findings indicated how health beliefs and cultural practices influenced behavior in preventing type 2 diabetes (T2D). Future research should focus on other high-risk minority groups (South Asian, Caribbean, and Latin American) to examine their health beliefs and cultural practices and use these finding to develop best practice guidelines, which should be incorporated into culturally tailored interventions.
