Association between household food insecurity and annual health care costs

Challenges of Food Insecurity Indicators, Diet Quality and Weight Outcomes in Women: A Cross-Sectional Study

Household food insecurity (FI) is a complex and multidimensional phenomenon. Despite much debate on FI, during the past decades several unaccounted aspects that are assumed to affect the FI of women still remain. Reducing the FI requires understanding its determinants. During this cross-sectional study (Jun to May of 2017), 188 women (19 ~ 64 years of age) were recruited in Sardrood-Tabriz, North-East Iran using cluster, random, and systematic sampling methods. Outcomes included socio-demographics, body compositions, anthropometric incidences, degree of FI, and five-item healthy eating scores (HES-5). Food security was classified as follows: high, marginal, low, and very low (HFS, MFS, LFS, and VLFS, respectively). Based on multiple logistic regression scores, significant relationships were found between household food security status and occupation, education level of household supervisor, number of girls and boys in the family, the household income level, and HES-5 [odds ratios (OR)=2.92; P=0.02, OR=46.57; P=0.03, OR=2.43; P=0.02, OR=2.56; P=0.005, OR=3.84; P=0.009, and OR=1.67; P<0.001, respectively], after adjusting for other factors. Influences inversely affecting diet quality and anthropometric indices may contribute to poor health status in affected women.

A pilot study of an online produce market combined with a fruit and vegetable prescription program for rural families

•

Rural families are at risk for diet-related diseases because of food disparities.

•

An online produce market increases redemption of produce prescriptions.

•

Photovoice illuminates the benefits and limits of produce prescription programs.

•

Produce prescriptions, online produce market, and cooking lessons affect behavior.

•

Fruit and vegetable consumption increases for families when they cook together.

Despite being surrounded by farms, rural families are often at risk for diet-related diseases because of food disparities. Barriers such as distance and transportation to a full service grocery store, lack of cooking knowledge and skills, and the cost of fresh produce, force families to shop at convenience stores that carry predominantly unhealthy, processed foods. We combined a Fruit and Vegetable Prescription Program (F&VRx) with family cooking/nutrition classes and a pilot online produce shopping to promote lifestyle dietary changes in rural families. In 2 rural upstate New York communities school health staff referred low income families with one or more children at risk for chronic disease related to obesity for this pilot program. Each family was given a weekly online produce credit for 5 months, September/October 2017 through January/February 2018. Two monthly nutrition/cooking lessons were provided for the entire family. Evaluation was done using pre and post program surveys and Photovoice. Families took photos in response to the question “How has the F&VRx program affected my family?”. Redemption of online produce credit was 94% and class attendance was 80%. Fruit and vegetable consumption rose for children. Confidence, culinary skills, and food literacy increased slightly. Three months after program completion, 60% of the families continued weekly online produce shopping without the F&VRx. Healthy behaviors for shopping, preparing, and consuming fruits and vegetables can be increased using a F&VRx, online produce ordering, and family cooking classes.

Homeownership status and risk of food insecurity: examining the role of housing debt, housing expenditure and housing asset using a cross-sectional population-based survey of Canadian households

BACKGROUND

Household food insecurity is a potent marker of material deprivation with adverse health consequences. Studies have repeatedly found a strong, independent relationship between owning a home and lower vulnerability to food insecurity in Canada and elsewhere, but the reasons for this relationship are poorly understood. We aimed to examine the influence of housing asset, housing debt and housing expenditure on the relationship between homeownership status and food insecurity in Canada.

METHODS

Cross-sectional data on food insecurity, housing tenure and expenditures, home value, income and sociodemographic characteristics were derived from the 2010 Survey of Household Spending, a population-based survey. Multivariable logistic regression models were conducted to estimate odds ratios of food insecurity among households of all incomes (n = 10,815) and those with lower incomes (n = 5547).

RESULTS

Food insecurity prevalence was highest among market renters (28.5%), followed by homeowners with a mortgage (11.6%) and mortgage-free homeowners (4.3%). Homeowners with a mortgage (OR: 0.51, 95% CI: 0.39-0.68) and those without a mortgage (OR: 0.23, 95% CI: 0.16-0.35) had substantially lower adjusted odds of food insecurity than market renters, and accounting for the burden of housing cost had minimal impact on the association. Mortgage-free homeowners had lower adjusted odds ratios of food insecurity compared to homeowners with a mortgage, but differences in the burden of housing cost fully accounted for the association. When stratifying homeowners based on presence of mortgage and housing asset level, the adjusted odds ratios of food insecurity for market renters were not significant when compared to mortgage holders with low housing asset. Mortgage-free owners with higher housing asset were least vulnerable to food insecurity (adjusted OR: 0.18, 95% CI: 0.11-0.27).

CONCLUSIONS

Substantial disparities in food insecurity exist between households with different homeownership status and housing asset level. Housing policies that support homeownership while ensuring affordable mortgages may be important to mitigate food insecurity, but policy actions are required to address renters' high vulnerability to food insecurity.

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

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

Who uses foodbanks and why? Exploring the impact of financial strain and adverse life events on food insecurity

Background

Rising use of foodbanks highlights food insecurity in the UK. Adverse life events (e.g. unemployment, benefit delays or sanctions) and financial strains are thought to be the drivers of foodbank use. This research aimed to explore who uses foodbanks, and factors associated with increased food insecurity.

Methods

We surveyed those seeking help from front line crisis providers from foodbanks (N = 270) and a comparison group from Advice Centres (ACs) (N = 245) in relation to demographics, adverse life events, financial strain and household food security.

Results

About 55.9% of foodbank users were women and the majority were in receipt of benefits (64.8%). Benefit delays (31.9%), changes (11.1%) and low income (19.6%) were the most common reasons given for referral. Compared to AC users, there were more foodbank users who were single men without children, unemployed, currently homeless, experiencing more financial strain and adverse life events (P = 0.001). Food insecurity was high in both populations, and more severe if they also reported financial strain and adverse life events.

Conclusions

Benefit-related problems appear to be a key reason for foodbank referral. By comparison with other disadvantaged groups, foodbank users experienced more financial strain, adverse life events, both increased the severity of food insecurity.

Combined effects of disease management and food insecurity on physical and mental health in Korean adults

OBJECTIVE

The present study aimed to examine the combined effects of disease management and food insecurity on physical and mental health in a representative Korean population.

DESIGN

A cross-sectional study.

SETTING

Data from the Korea National Health and Nutrition Examination Survey (KNHANES) 2012-2015.

PARTICIPANTS

Adults aged ≥30 years (n 17 934) who participated in the KNHANES.

RESULTS

Among health-care factors, unmet health-care needs and mental health counselling were different by food insecurity status, with a higher prevalence in adults with food insecurity. The prevalence of underweight was higher in men with food insecurity (5·9 %), whereas the prevalence of obesity was higher in women with food insecurity (37·4 %), than that in men and women with food security. Food insecurity was associated with a high risk of all mental health outcomes. For the combined effects of disease management and food insecurity, unmet health-care needs was related to increased risk of obesity for food-insecure men (Pinteraction = 0·029) and lack of participation in nutrition education or counselling was related to increased risk of obesity for food-insecure women (Pinteraction = 0·010). In addition, higher unmet health-care needs in adults with food insecurity was related to higher risk of mental health outcomes.

CONCLUSIONS

Unmet health-care needs may exacerbate obesity for food-insecure men and mental health problems for both food-insecure men and women. In addition, lack of participation in nutrition education or counselling may exacerbate the obesity for food-insecure women.

Defining 'actionable' high- costhealth care use: results using the Canadian Institute for Health Information population grouping methodology

Background

A small proportion of the population consumes the majority of health care resources. High-cost health care users are a heterogeneous group. We aim to segment a provincial population into relevant homogenous sub-groups to provide actionable information on risk factors associated with high-cost health care use within sub-populations.

Methods

The Canadian Institute for Health Information (CIHI) Population Grouping methodology was used to define mutually exclusive and clinically relevant health profile sub-groups. High-cost users (> = 90th percentile of health care spending) were defined within each sub-group. Univariate analyses explored demographic, socio-economic status, health status and health care utilization variables associated with high-cost use. Multivariable logistic regression models were constructed for the costliest health profile groups.

Results

From 2015 to 2017, 1,175,147 individuals were identified for study. High-cost users consumed 41% of total health care resources. Average annual health care spending for individuals not high-cost were $642; high-cost users were $16,316. The costliest health profile groups were ‘long-term care’, ‘palliative’, ‘major acute’, ‘major chronic’, ‘major cancer’, ‘major newborn’, ‘major mental health’ and ‘moderate chronic’. Both ‘major acute’ and ‘major cancer’ health profile groups were largely explained by measures of health care utilization and multi-morbidity. In the remaining costliest health profile groups modelled, ‘major chronic’, ‘moderate chronic’, ‘major newborn’ and ‘other mental health’, a measure of socio-economic status, low neighbourhood income, was statistically significantly associated with high-cost use.

Interpretation

Model results point to specific, actionable information within clinically meaningful subgroups to reduce high-cost health care use. Health equity, specifically low socio-economic status, was statistically significantly associated with high-cost use in the majority of health profile sub-groups. Population segmentation methods, and more specifically, the CIHI Population Grouping Methodology, provide specificity to high-cost health care use; informing interventions aimed at reducing health care costs and improving population health.

Food insecurity and socio-demographic characteristics in two UK ethnic groups: an analysis of women in the Born in Bradford cohort

Background

The use of foodbanks has risen sharply in the UK; however, the epidemiology of UK food insecurity is undeveloped. This study contributes to the field by analysing socio-demographic risk factors for food insecurity in a female, ethnically diverse population.

Methods

Data from the Born in Bradford (BiB) cohort were matched with data on food insecurity from the nested BiB1000 study (N = 1280). Logistic regression was used to model food insecurity in relation to ethnicity and socio-demographic factors.

Results

Food insecurity, reported by 13.98% of the sample, was more likely among White British than Pakistani women (crude Odds Ratio (OR) 1.94, 95% CI: 1.37; 2.74, adjusted OR 2.37, 95% CI: 1.57; 3.59). In fully adjusted analyses, food insecurity was associated with a range of socio-economic measures, particularly the receipt of mean-tested benefits (adjusted OR 2.11, 95% CI: 1.41; 3.15) and perception of financial insecurity (adjusted OR 8.91, 95% CI: 4.14; 19.16 for finding it difficult/very difficult compared to living comfortably).

Conclusions

The finding that food insecurity prevalence may be higher than previously thought and that food insecurity is highly associated with socio-economic status, notably benefit receipt, is a cause for concern necessitating an urgent policy response.

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.

Screening for poverty and intervening in a primary care setting: an acceptability and feasibility study

BACKGROUND

A movement is emerging to encourage health providers and health organizations to take action on the social determinants of health. However, few evidence-based interventions exist. Digital tools have not been examined in depth.

OBJECTIVE

To assess the acceptability and feasibility of integrating, within routine primary care, screening for poverty and an online tool that helps identify financial benefits.

METHODS

The setting was a Community Health Centre serving a large number of low-income individuals in Toronto, Canada. Physicians were encouraged to use the tool at every possible encounter during a 1-month period. A link to the tool was easily accessible, and reminder emails were circulated regularly. This mixed-methods study used a combination of pre-intervention and post-intervention surveys, focus groups and interviews.

RESULTS

Thirteen physicians participated (81.25% of all) and represented a range of genders and years in practice. Physicians reported a strong awareness of the importance of identifying poverty as a health concern, but low confidence in their ability to address poverty. The tool was used with 63 patients over a 1-month period. Although screening and intervening on poverty is logistically challenging in regular workflows, online tools could assist patients and health providers identify financial benefits quickly. Future interventions should include more robust follow-up.

CONCLUSIONS

Our study contributes to the evidence based on addressing the social determinants of health in clinical settings. Future approaches could involve routine screening, engaging other members of the team in intervening and following up, and better integration with the electronic health record.

The Hunger Vital Sign Identifies Household Food Insecurity among Children in Emergency Departments and Primary Care

This study aimed: (1) to examine the sensitivity and specificity of the 2-item Hunger Vital Sign against the 18-item Household Food Security Survey Module (HFSSM) in identifying young children in food insecure households in emergency department and primary care sites and (2) to examine associations between food insecurity and adverse health conditions. We conducted cross-sectional surveys from 2009-2017 among 5039 caregivers of children age <48 months. We measured adverse child health by caregiver-reported perceived health, prior hospitalizations, and developmental risk (Parents' Evaluation of Developmental Status). Analyses were conducted using covariate-adjusted logistic regression. Sensitivity and specificity of the Hunger Vital Sign against the HFSSM were 96.7% and 86.2%. Using the HFSSM, children in the emergency department had a 28% increase in the odds of experiencing food insecurity, compared to children in primary care, aOR = 1.28, 95% Confidence Interval (CI) = 1.08-1.52, p = 0.005. Using the Hunger Vital Sign, the increase was 26%, aOR = 1.26, 95% CI = 1.08-1.46, and p = 0.003. The odds of children's adverse health conditions were significantly greater in food insecure households, compared to food secure households, using either HFSSM or the Hunger Vital Sign. Screening for food insecurity with the Hunger Vital Sign identifies children at risk for adverse health conditions in both primary care and emergency department sites, and can be used to connect families with resources to alleviate food insecurity.

Use of Survival Analysis to Predict Attrition Among Women Participating in Longitudinal Community-Based Nutrition Research

OBJECTIVE

To identify participant characteristics and study methodology that influenced the completion of a 15-month community-based longitudinal study evaluating the impact of the Supplemental Nutrition Assistance Program Education and Expanded Food and Nutrition Education Program.

DESIGN

Observational longitudinal 15-month study across 12 data collection timepoints. Sociodemographic characteristics were collected with a paper-based survey at baseline.

SETTING

Five counties across central and southern Illinois.

PARTICIPANTS

Women, aged 18 to 65 years (n = 297), recruited at sites likely to serve families eligible for the Supplemental Nutrition Assistance Program Education and Expanded Food and Nutrition Education Program (housing departments, child care centers, etc).

MAIN OUTCOME MEASURES

Predictors of participant attrition during the study duration.

ANALYSIS

Cox proportional hazard models.

RESULTS

Ninety-seven participants were retained across the full study. In unadjusted models, greater income and education levels were significantly related to lower attrition; however, this relationship did not persist in a multivariate model. When adjusted for other characteristics, larger household size was the only measured variable significantly related to greater odds of attrition (odds ratio = 1.09; 95% confidence interval = 1.02, 1.17).

CONCLUSIONS AND IMPLICATIONS

Several characteristics predicting attrition in other settings were not significant in this study. Future attrition analyses that evaluate social support, transportation capacity, and type of phone in longitudinal nutrition education studies are warranted.

SNAP, Young Children's Health, and Family Food Security and Healthcare Access

INTRODUCTION

The Supplemental Nutrition Assistance Program (SNAP) is the largest nutrition assistance program in the U.S. This study's objective was to examine the associations between SNAP participation and young children's health and development, caregiver health, and family economic hardships.

METHODS

Cross-sectional data from 2006 to 2016 were analyzed in 2017 for families with children aged <3 years in 5 cities. Generalized estimating equations and logistic regression were used to evaluate the associations of SNAP participation with child and caregiver health outcomes and food insecurity, forgone health care, and health cost sacrifices. Nonparticipants that were likely to be eligible for SNAP were compared with SNAP participants and analyses adjusted for covariates including Consumer Price Index for food to control for site-specific food prices.

RESULTS

The adjusted odds of fair or poor child health status (AOR=0.92, 95% CI=0.86, 0.98), developmental risk (AOR=0.82, 95% CI=0.69, 0.96), underweight, and obesity in children were lower among SNAP participants than among nonparticipants. In addition, food insecurity in households and among children, and health cost sacrifices were lower among SNAP participants than among nonparticipants.

CONCLUSIONS

Participation in SNAP is associated with reduced household and child food insecurity, lower odds of poor health and growth and developmental risk among infants and toddlers, and reduced hardships because of healthcare costs for their families. Improved SNAP participation and increased SNAP benefits that match the regional cost of food may be effective preventive health strategies for promoting the well-being of families with young children.

"We have a roof over our head, but we have to eat too:" Exploring shifting foodscapes from homelessness into Housing First in Kingston, Ontario

BACKGROUND

People facing extended periods of homelessness exhibit a remarkable degree of agency and resilience in procuring food. The literature on foodscapes considers the sociospatial contexts of food procurement, finding that what happens within and along the way to sites of food acquisition and consumption are important considerations in fully understanding and realizing food security.

PURPOSE

This study explores the shift in foodscapes of people who are transitioning from homelessness into scattered-site independent housing via a municipal Housing First program and considers implications for health and wellbeing.

METHODS

Our mixed-method approach included observational research at 11 local food providers and drop-in centres that provided context for semi-structured interviews with 10 Housing First clients in Kingston, Ontario between November 2016 and March 2017.

RESULTS

The findings confirm that the provision of stable housing makes it possible for people to store, prepare, and consume food at home. An increased ability to have control over when, where, and what is eaten had a positive impact on people's sense of health and wellbeing. However, other effective markers of wellbeing were enacted along people's everyday routines and activities that had negative impacts. Interviewees remained heavily dependent on charitable food programs, including increased use of foodbanks. Others reported increasing detachment and social isolation from previously established food routines. Finally, the structured transition perpetuated a circuit of dependence and marginalization that fell short of contributing to improved food security as well as health and wellbeing.

IMPLICATIONS

Understanding the relational geography of foodscape transitions is critical to the design of effective Housing First programs. Addressing the root causes of homelessness and poverty requires investments in comprehensive housing strategies including adequate social assistance and community supports that take a sociospatially holistic approach to wellbeing.

Outcomes of disease prevention and management interventions in food pantries and food banks: a scoping review

OBJECTIVE

Food insecurity affects millions of Americans and is associated with a range of adverse health outcomes. Food insecure individuals often obtain food from food pantries/banks, prompting health researchers to implement disease prevention/management interventions at these sites. This review examined the existing peer-reviewed research on disease prevention/management interventions implemented in food pantries/banks.

DESIGN

Scoping review.

DATA SOURCES

Databases searched included MEDLINE, Web of Science, CINAHL and Cochrane. Search strategies included Medical Subject Headings and key terms, including food pantry, food bank, food shelf, food aid and related concepts.

ELIGIBILITY CRITERIA

Studies were included if they described an intervention involving food pantries/banks where at least one biometric indicator was included as an outcome variable. Articles focused solely on the quality of foods distributed, the diet quality of food pantry/bank clients or government food aid programmes were excluded.

DATA EXTRACTION AND SYNTHESIS

Extracted data included publication details, intervention type, study design, participant characteristics, study outcomes, and barriers and facilitators of intervention implementation.

RESULTS

A total of 3317 articles were assessed for eligibility. Six studies met the predefined inclusion criteria. The studies employed a range of intervention approaches to manage or prevent a number of chronic diseases, including obesity, type 2 diabetes and HIV. The studies examined a range of biometric outcomes, including body mass index, glycated haemoglobin and blood pressure. Information about the food pantries/banks where the interventions were conducted was lacking. The studies documented multiple barriers and facilitators related to costs, sustainability and organisational capacity.

CONCLUSIONS

To our knowledge, this is the first review to examine disease prevention and management interventions conducted in food pantries and food banks. Given the high number of households who obtain food from food pantries/banks and the chronic health conditions associated with food insecurity, this review highlights the need for more high-quality research in this setting.

Is food insecurity related to health-care use, access and absenteeism?

OBJECTIVE

Food insecurity (FI) is defined as uncertain access to healthy food in quantity and quality. We hypothesize that FI may be associated with greater health-care use and absenteeism because it may amplify the effect of diseases; also, FI may be associated with reduced health-care access because it reflects economic vulnerability. The present study estimates the association between FI and health-care use and access, and absenteeism.

DESIGN

Cross-sectional data collected in 2015-2016. Health-care use was measured as the number of consultations, taking any drug and having been hospitalized in the past year. Health-care access was measured by the suspension of medication and having fewer consultations due to financial constraints. Absenteeism was measured by the weeks of sickness leave. Binary variables were modelled as a function of FI using logistic regressions; continuous variables were modelled as a function of FI using negative binomial and zero-inflated negative binomial regressions. Covariates were included sequentially.

SETTING

Portugal.

PARTICIPANTS

Non-institutionalized adults from the EpiDoc3 cohort (n 5648).

RESULTS

FI was significantly associated with health-care use before controlling for socio-economic conditions and quality of life. Moderate/severe FI was positively related to the suspension of medicines (adjusted OR = 4·68; 95 % CI 3·11, 6·82) and to having fewer consultations (adjusted OR = 3·98; 95 % CI 2·42, 6·37). FI and absenteeism were not significantly associated.

CONCLUSIONS

Our results support the hypothesis that FI reflects precariousness, which hinders access to health care. The greater use of health care among food-insecure people is explained by their worse quality of life and lower socio-economic condition, so that the specific role of poor nutrition is unclear.

Food Security Status and Hair Cortisol among Low-income Mother-Child Dyads

This cross-sectional study among low-income mother-child dyads examined the relationship between food security status and hair cortisol concentration (HCC), and how mother and child food security status was interactively related to mothers' perceived distress and coping. Data from 32 dyads were analyzed. Approximately 46.9% had household food insecurity, 37.5% children had food insecurity, and 34.4% mothers had food insecurity. Children with food insecurity had significantly higher HCC than those with food security. A significant interaction effect occurred between child food security status and race on children's HCC, with White children's HCC being more likely to be influenced by food security status. Mother food security and child food security status together explained about 6% of the variance in mothers' HCC, 27% in perceived distress, and 18% in perceived coping. These findings indicate that assisting low-income families with food insecurity to get enough food can benefit both children's and mothers' mental health.

The Climate Change, Food Security and Human Health Nexus in Canada: A Framework to Protect Population Health

Climate change impacts on the Canadian food system pose risks to human health. Little attention has been paid to the climate change, food security, and human health nexus, resulting in a number of knowledge gaps regarding food system components that are most vulnerable to climate change. The lack of understanding of key dynamics and possible future impacts challenges the ability of public health officials and partners in other sectors to prepare Canadians for future health risks. A series of literature reviews were conducted to establish the relationship between climate change, food security, and human health, and to identify vulnerabilities within the Canadian food system. Evidence suggests that key activities within the food system are vulnerable to climate change. The pathways in which climate change impacts travel through the food system and affect the critical dimensions of food security to influence human health outcomes are complex. Climate-related disruptions in the food system can indirectly impact human health by diminishing food security, which is a key determinant of health. Human health may also be directly affected by the physical effects of climate change on the food system, primarily related to the impacts on nutrition and foodborne illnesses. In this study, we propose a novel analytical framework to study and respond to the climate change, food security, and human health nexus. This work is intended to help public health officials, researchers, and relevant stakeholders investigate and understand current and future risks, and inform adaptation efforts to protect the health of Canadians.

State-Level and County-Level Estimates of Health Care Costs Associated with Food Insecurity

INTRODUCTION

Food insecurity, or uncertain access to food because of limited financial resources, is associated with higher health care expenditures. However, both food insecurity prevalence and health care spending vary widely in the United States. To inform public policy, we estimated state-level and county-level health care expenditures associated with food insecurity.

METHODS

We used linked 2011-2013 National Health Interview Survey/Medical Expenditure Panel Survey data (NHIS/MEPS) data to estimate average health care costs associated with food insecurity, Map the Meal Gap data to estimate state-level and county-level food insecurity prevalence (current though 2016), and Dartmouth Atlas of Health Care data to account for local variation in health care prices and intensity of use. We used targeted maximum likelihood estimation to estimate health care costs associated with food insecurity, separately for adults and children, adjusting for sociodemographic characteristics.

RESULTS

Among NHIS/MEPS participants, 10,054 adults and 3,871 children met inclusion criteria. Model estimates indicated that food insecure adults had annual health care expenditures that were $1,834 (95% confidence interval [CI], $1,073-$2,595, P < .001) higher than food secure adults. For children, estimates were $80 higher, but this finding was not significant (95% CI, -$171 to $329, P = .53). The median annual health care cost associated with food insecurity was $687,041,000 (25th percentile, $239,675,000; 75th percentile, $1,140,291,000). The median annual county-level health care cost associated with food insecurity was $4,433,000 (25th percentile, $1,774,000; 75th percentile, $11,267,000). Cost variability was related primarily to food insecurity prevalence.

CONCLUSIONS

Health care expenditures associated with food insecurity vary substantially across states and counties. Food insecurity policies may be important mechanisms to contain health care expenditures.

Food Insecurity in Portugal Among Middle- and Older-Aged Adults at a Time of Economic Crisis Recovery: Prevalence and Determinants

BACKGROUND

To characterize the scenario of food insecurity in Portugal at a time of economic crisis recovery is of the utmost relevance.

OBJECTIVE

This study aimed to estimate the prevalence and to identify the determinants of food insecurity during economic crisis recovery in a population-based urban sample of middle- and older-aged Portuguese adults.

METHODS

A cross-sectional study including 604 participants of the EPIPorto cohort was conducted. Data on sociodemographic characteristics and on food security status were collected. Food security status was assessed using the US Household Food Security Survey Module: Six-Item Short Form. Logistic regression models, crude and adjusted for sex, age, education, and household income perception, were performed.

RESULTS

The prevalence of food insecurity was 16.6%. Women (odds ratio [OR] = 1.96; 95% confidence interval [CI]: 1.09-3.54), those less educated (OR = 5.46; 95% CI: 2.84-10.46), and those who had the perception of an insufficient household income (OR = 10.39; 95% CI: 5.00-21.56) were more likely to belong to a food insecure household. Unmarried individuals (OR = 1.79; 95% CI: 1.05-3.06) and lower white-collar workers (OR = 2.22; 95% CI: 1.03-4.77) were also more prone to live within a food insecure household, regardless of sex, age, education, and household income perception.

CONCLUSIONS

The obtained information is valuable for the development of intervention strategies to reduce food insecurity in middle- and older-aged adults, suggesting that women, unmarried, less educated individuals, less skilled workers, and lower income families should be targeted.

Cost of hospital care for the older adults according to their level of frailty. A cohort study in the Lazio region, Italy

Background

The increasing burden of chronic diseases associated with the ageing of the European population constitutes one of the main challenges for the welfare systems in developed western countries, especially through its impact on the use of hospital services and the cost of care. This study aims at evaluating the cost of hospital care for older adults living in the Lazio Region, Italy, according to their level of frailty.

Methods

Since 2014 a longitudinal randomized cohort study has been carried out on a sample consisting of 1280 older adults aged over 64 years resident in the Lazio region (Italy), with their being evaluated for multidimensional frailty. Accesses to Hospital Services (acute care and Day Hospital care admissions and Emergency Room accesses) during the first year after enrolment, as well as the related costs have been recorded through a regional database. Costs have been stratified on the basis of the state of frailty.

Results

The analysis of hospital services and costs highlights the role played by pre-frail individuals who generated 49.3% of the hospital care cumulative costs. Hospital Admission (HA) costs arising from robust and pre-frail subjects are 70% of the total HA costs. Pre-frail individuals also showed the highest average HA cost per person/year (7062.89 Euros). The main determinant of the highest HA costs was given by the number of HAs during the follow-up (multivariate linear regression, ß coefficient = 0.319; p<0.001), which was higher among pre-frail individuals than in any other group of patients.

Conclusions

Pre-frail individuals generated the highest cost for hospital care in a sample of representative subjects living in an Italian Region with a low rate of community care services, as is the case in the Lazio region. Assessment of the multidimensional frailty of older adults permits a better definition of the important target of the pre-frail population as the main category within which interventions to prevent or mitigate frailty should be carried out.

Food insecurity in Nunavut following the introduction of Nutrition North Canada

BACKGROUND

Household food insecurity, a measure of income-related problems of food access, is a pressing public health problem in Canada's North, especially in Nunavut. We aimed to assess the impact of Nutrition North Canada, a food retail subsidy intended to improve food access and affordability in isolated communities, on household food insecurity in Nunavut.

METHODS

Using data from 3250 Nunavut households sampled in the annual components of the Canadian Community Health Survey (2007 to 2016), we conducted interrupted time series regression analyses to determine whether the introduction of Nutrition North Canada was associated with changes in the rates of self-reported food insecurity, according to a validated instrument. We used propensity score weighting to control for several sociodemographic characteristics associated with food insecurity.

RESULTS

Food insecurity affected 33.1% of households in 2010 (the year before the launch of Nutrition North Canada), 39.4% of households in 2011 (the year of the launch) and 46.6% of households in 2014 (the year after full implementation). After controlling for several covariates, we found the rate of food insecurity increased by 13.2 percentage points (95% confidence interval [CI] 1.7 to 24.7) after the full implementation of the subsidy program, and the increase in food insecurity first occurred in 2011 (9.6 percentage points, 95% CI 2.7 to 16.4), the year Nutrition North Canada was launched.

INTERPRETATION

Food insecurity was a pervasive problem in Nunavut before Nutrition North Canada, but it has become even more prevalent since the program was implemented. Given the important health consequences of food insecurity, more effective initiatives to address food insecurity in Canada's North are urgently needed.

Food bank operational characteristics and rates of food bank use across Britain

Background

Food banks are a common community-based response to household food insecurity in high-income countries. While the profile of their users and nature of the quality of food they provide have been researched, few studies have examined their operational characteristics to explore the accessibility of their services for people at risk of food insecurity. This study describes the nature of operations in a food bank network operating in Britain and explores how operations are associated with volume of use.

Methods

Data from The Trussell Trust Foodbank’s network of 1145 distribution centres in 2015/16 on hours of operation, locations, and usage were combined with national statistics on Working Tax Credit claimants, disability and unemployment. Descriptive statistics focused on how often and when food banks were open within local authorities. The relationships between operational characteristics and volume of use were examined using regression analyses. Interaction terms tested how relationships between indicators of need with food bank usage changed with operational characteristics.

Results

Weekday operating hours were primarily between the hours of 10 a.m. and 2 p.m., but at any given hour no more than 20% of distribution centres were open, with fewer than 3% open after 4 pm. Where food banks had fewer distribution centres and operating hours, the volume of food bank usage was lower. In-work poverty, disability, and unemployment rates were all associated with higher volume of usage; however, the relationship between disability and food bank use was modified by the density of food banks and number of operating hours. Where food banks were less accessible, the relationship between disability and food bank use was diminished.

Conclusions

These findings suggest operational characteristics are an important part of access to food banks and raise questions about the ability of food banks to meet the needs of people at risk of food insecurity in Britain.

Food Security and 10-Year Cardiovascular Disease Risk Among U.S. Adults

INTRODUCTION

Cardiovascular disease is a leading cause of mortality in the U.S. Although the risk of cardiovascular disease can be mitigated substantially by following a healthy lifestyle, adhering to a healthy diet and other healthy behaviors are limited by reduced food security. This study aims to determine the association between food security and cardiovascular disease risk.

METHODS

Three samples from the 2007-2014 National Health and Nutrition Examination Survey were examined: (1) 7,340 non-fasting adults (aged 40-79 years); (2) 13,518 non-fasting adults (aged 20-64 years); and (3) 6,494 fasting adults (aged 20-64 years). Food security was assessed using the U.S. Household Food Security Survey Module, with households categorized as having full, marginal, low, or very low food security. Regressions were conducted in 2018 to test the associations between food security status and odds of ≥20% 10-year cardiovascular disease risk among middle-aged to older adults (OR, 95% CI) and cardiovascular disease risk factors among all adults (β, 95% CI).

RESULTS

Compared with adults with full food security, those with very low food security had higher odds of ≥20% 10-year cardiovascular disease risk (OR=2.36, 95% CI=1.25, 4.46), whereas those with marginal food security had higher systolic blood pressure (β=0.94 mmHg, 95% CI=0.09, 1.80). Compared with adults with full food security, adults with different levels of food security had higher BMIs (marginal: 0.76, 95% CI=0.26, 1.26; low: 0.97, 95% CI=0.34, 1.60; and very low: 1.03, 95% CI=0.44, 1.63) and higher odds of current smoking (marginal: OR=1.43, 95% CI=1.17, 1.75; low: OR=1.47, 95% CI=1.22, 1.77; and very low: OR=1.95, 95% CI=1.60, 2.37).

CONCLUSIONS

Adults with food insecurity have elevated cardiovascular disease risk factors and excess predicted 10-year cardiovascular disease risk. Substantially improving food security may be an important public health intervention to reduce future cardiovascular disease in the U.S.

The rise of hunger among low-income households: an analysis of the risks of food insecurity between 2004 and 2016 in a population-based study of UK adults

Background

Rising food bank use in the past decade in the UK raises questions about whether food insecurity has increased. Using the 2016 Food and You survey, we describe the magnitude and severity of the problem, examine characteristics associated with severity of food insecurity, and examine how vulnerability has changed among low-income households by comparing 2016 data to the 2004 Low Income Diet and Nutrition Survey.

Methods

The Food and You survey is a representative survey of adults living in England, Wales, and Northern Ireland (n=3118). Generalised ordered logistic regression models were used to examine how socioeconomic characteristics related to severity of food insecurity. Coarsened exact matching was used to match respondents to respondents in the 2004 survey. Logistic regression models were used to examine if food insecurity rose between survey years.

Results

20.7% (95% CI 18.7% to 22.8%) of adults experienced food insecurity in 2016, and 2.72% (95% CI 2.07% to 3.58%) were severely food insecure. Younger age, non-white ethnicity, low education, disability, unemployment, and low income were all associated with food insecurity, but only the latter three characteristics were associated with severe food insecurity. Controlling for socioeconomic variables, the probability of low-income adults being food insecure rose from 27.7% (95% CI 24.8% to 30.6 %) in 2004 to 45.8% (95% CI 41.6% to 49.9%) in 2016. The rise was most pronounced for people with disabilities.

Conclusions

Food insecurity affects economically deprived groups in the UK, but unemployment, disability and low income are characteristics specifically associated with severe food insecurity. Vulnerability to food insecurity has worsened among low-income adults since 2004, particularly among those with disabilities.

Medically Tailored Meals as a Prescription for Treatment of Food-Insecure Type 2 Diabetics

Type 2 diabetes mellitus is an immense burden to the health of our population and to our current health care system, and the weight of this burden is only projected to multiply in coming years. A nutritious diet is an indispensable aspect of diabetes treatment, and the lack of access to food engenders poor disease-state control, which correlates with increased health care utilization. Interventions aimed at improving access to food through medically tailored meals (MTMs) have demonstrated effectiveness in improving the health of food-insecure type 2 diabetic patients and reducing health care costs. Further studies are necessary to increase the external validity of existing positive research on medically tailored meals in food-insecure diabetic patients and to provide evidence to support potential policy changes under which the costs of medically tailored meals for diabetics might be covered by insurers.

Aligning Programs and Policies to Support Food Security and Public Health Goals in the United States

Food insecurity affects 1 in 8 US households and has clear implications for population health disparities. We present a person-centered, multilevel framework for understanding how individuals living in food-insecure households cope with inadequate access to food themselves and within their households, communities, and broader food system. Many of these coping strategies can have an adverse impact on health, particularly when the coping strategies are sustained over time; others may be salutary for health. There exist multiple opportunities for aligning programs and policies so that they simultaneously support food security and improved diet quality in the interest of supporting improved health outcomes. Improved access to these programs and policies may reduce the need to rely on individual- and household-level strategies that may have negative implications for health across the life course.

Canadian Children from Food Insecure Households Experience Low Self-Esteem and Self-Efficacy for Healthy Lifestyle Choices

The objectives of this cross-sectional study were to: (i) determine whether there are differences in self-esteem and self-efficacy for healthy lifestyle choices between children living in food secure and food insecure households; and (ii) determine whether the association between household food insecurity (HFI), self-esteem and self-efficacy differs by gender. Survey responses of 5281 fifth-grade students (10 and 11 years of age) participating in the Canadian Children’s Lifestyle and School Performance Study II were analyzed using logistic and linear regression. HFI status was determined by the six-item short-form Household Food Security Survey Module (HFSSM). Students from food insecure households had significantly higher odds of low self-esteem, and significantly lower scores for global self-efficacy to make healthy choices, compared to students from food secure households. These associations were stronger for girls than for boys and appeared independent of parental educational attainment. Household income appeared to be the essential underlying determinant of the associations of food insecurity with self-esteem and self-efficacy. Upstream social policies such as improving the household income of low-income residents will reduce food insecurity and potentially improve self-esteem and self-efficacy for healthy choices among children. This may improve health and learning, and in the long term, job opportunities and household earnings.

The Good Food Revolution: Building Community Resiliency in the Mississippi Delta

The Mississippi Delta represents one of the greatest concentrations of rural persistent poverty in the United States. High unemployment, high food insecurity, higher rates of obesity and diabetes, and low access to healthy, affordable food characterize much of the 18 counties in the region. In the face of this, The Good Food Revolution, a community-based program to address food related health and thereby employment, developed in response to significant need in three small communities in North Bolivar County, Mississippi, bringing together community members, public and private sector organizations, researchers and students. This paper examines the process of community-engaged scholarship from the theoretical lens on building community capacity and resiliency developed by Chaskin. Increasing community capacity for all participants in the Good Food Revolution project through community-engaged scholarship has built resilient communities that are engaging more communities.

A Pediatric Fruit and Vegetable Prescription Program Increases Food Security in Low-Income Households

OBJECTIVE

To assess change in household food security associated with participation in a pediatric fruit/vegetable prescription program.

METHODS

The researchers analyzed clinic-based, fruit/vegetable prescription program data for 578 low-income families, collected in 2013-2015, and calculated changes in food security (summative score; high/low/very low; and individual US Department of Agriculture measures).

RESULTS

Of participating households, 72% increased their summative score over the course of the program. In adjusted regression models, participants had higher change scores with 5 or 6 clinical visits, compared with 1 or 2 visits (β = .07; 95% confidence interval, 0.01-0.14), and college education of the primary caretaker, compared with less than college (β = .05; 95% confidence interval, 0.01-0.09). Select clinic sites (but neither visit nor redemption proportions) significantly contributed to change score variance. All US Department of Agriculture measures saw significant increases.

CONCLUSIONS AND IMPLICATIONS

Fruit/vegetable prescription programs may help providers address patients' food insecurity. Further research using experimental designs and implementation science could build the case to incorporate programs into practice.

What can Secondary Data Tell Us about Household Food Insecurity in a High-Income Country Context?

In the absence of routinely collected household food insecurity data, this study investigated what could be determined about the nature and prevalence of household food insecurity in Scotland from secondary data. Secondary analysis of the Living Costs and Food Survey (2007–2012) was conducted to calculate weekly food expenditure and its ratio to equivalised income for households below average income (HBAI) and above average income (non-HBAI). Diet Quality Index (DQI) scores were calculated for this survey and the Scottish Health Survey (SHeS, 2008 and 2012). Secondary data provided a partial picture of food insecurity prevalence in Scotland, and a limited picture of differences in diet quality. In 2012, HBAI spent significantly less in absolute terms per week on food and non-alcoholic drinks (£53.85) compared to non-HBAI (£86.73), but proportionately more of their income (29% and 15% respectively). Poorer households were less likely to achieve recommended fruit and vegetable intakes than were more affluent households. The mean DQI score (SHeS data) of HBAI fell between 2008 and 2012, and was significantly lower than the mean score for non-HBAI in 2012. Secondary data are insufficient to generate the robust and comprehensive picture needed to monitor the incidence and prevalence of food insecurity in Scotland.

Food-Aid Quality Correlates Positively With Diet Quality of Food Pantry Users in the Leket Israel Food Bank Collaborative

Introduction: In many affluent countries, including Israel, networks of food banks and pantries have increasing responsibility to alleviate endemic poverty and food insecurity. While they may relieve acute hunger, their long-term influence on health and well-being is poorly understood.

Methods: An exploratory cross-sectional telephone survey assessed both adequacy and quality of food aid provided via food pantries in the Leket Israel food bank network, in relation to recipients' dietary needs and health. The quality of food baskets and recipient diets were given a Healthy Portions Score (HPS) to measure compliance with Government guidelines for a “Basic Healthy Food Basket,” and a Nutrient Density Score (NDS) to capture how well the food achieved the recommended dietary allowance (RDA) for vital macro and micronutrients. A total of 105 pantry users were surveyed from 16 pantries around the country.

Results: The basket HPS correlated positively and highly significantly with dietary quality (individual NDS) after adjusting for gender, marital status and country of birth (standardized β = 0.22, p = 0.03). Nearly half (46%) reported food insecurity with hunger. Two thirds were overweight or obese, and anemia, cardiovascular and metabolic disease were prevalent. The average food basket provides 30% of energy, 55% of protein, 50% of fiber, but only 33% or less of the household requirement for most minerals and vitamins. Only 60% of participants met their estimated energy requirements, and the intake of many essential micronutrients was well below the RDA. Fruits and vegetable portions contributed by Leket Israel correlated positively with the dietary quality (individual NDS) after adjustment for the same covariates (Standardized β = 0.20, p = 0.04).

Discussion: A structured telephone survey proved a feasible method to study the impact of food-aid quality on the nutrition and health of food pantry users in an affluent country. Food baskets with fruits, vegetables and higher quality nutrition were correlated with healthier diets among the recipients. Data correlating food-aid quality and recipient diet and health is essential to effective policy making.

The effect of socio-demographic factors on mental health and addiction high-cost use: a retrospective, population-based study in Saskatchewan

OBJECTIVE

A small proportion of the population accounts for the majority of healthcare costs. Mental health and addiction (MHA) patients are consistently high-cost. We aimed to delineate factors amenable to public health action that may reduce high-cost use among a cohort of MHA clients in Saskatoon, Saskatchewan.

METHODS

We conducted a population-based retrospective cohort study. Administrative health data from fiscal years (FY) 2009-2015, linked at the individual level, were analyzed (n = 129,932). The outcome of interest was ≥ 90th percentile of costs for each year under study ('persistent high-cost use'). Descriptive analyses were followed by logistic regression modelling; the latter excluded long-term care residents.

RESULTS

The average healthcare cost among study cohort members in FY 2009 was ~ $2300; for high-cost users it was ~ $19,000. Individuals with unstable housing and hospitalization(s) had increased risk of persistent high-cost use; both of these effects were more pronounced as comorbidities increased. Patients with schizophrenia, particularly those under 50 years old, had increased probability of persistent high-cost use. The probability of persistent high-cost use decreased with good connection to a primary care provider; this effect was more pronounced as the number of mental health conditions increased.

CONCLUSION

Despite constituting only 5% of the study cohort, persistent high-cost MHA clients (n = 6455) accounted for ~ 35% of total costs. Efforts to reduce high-cost use should focus on reduction of multimorbidity, connection to a primary care provider (particularly for those with more than one MHA), young patients with schizophrenia, and adequately addressing housing stability.

Food Insecurity is Associated with Maladaptive Eating Behaviors and Objectively Measured Overeating

OBJECTIVE

The association between food insecurity and obesity may be partially explained by overeating in response to unpredictable food availability cycles. The aim of this study was to measure objective food intake in food-insecure individuals.

METHODS

Eighty-two volunteers (53 m; BMI 29 ± 7; 38 ± 12 years) were admitted to our inpatient Clinical Research Unit and completed the Food Security Short Form, Three-Factor Eating Questionnaire, Gormally Binge Eating Scale, and body composition assessment (dual-energy x-ray absorptiometry). After 5 days of a weight-maintaining diet, participants self-selected food from an ad libitum vending machine paradigm for 3 days. Mean daily intake (kilocalories), macronutrient intake, and percentage of weight-maintaining energy needs (%WMEN) were calculated.

RESULTS

Based on Food Security Short Form cutoffs, food-insecure participants (n = 46; 56%) had higher body weight (P = 0.04), fat-free mass (P = 0.05), disinhibition (P = 0.008), hunger (P = 0.02), and binge-eating scores (P = 0.02) but not cognitive restraint (P = 0.37) compared with food-secure individuals. They overate more kilocalories (P = 0.001), %WMEN (P = 0.003), fat (P = 0.003), and carbohydrates (P = 0.004) during the vending machine paradigm, continued to increase their hourly rate of kilocalories (group × time; β = 37.7 cumulative kcal/h; P < 0.0001), and ate more total kilocalories across the 72 hours (β = 47.09 kcal/h; P = 0.003).

CONCLUSIONS

Food insecurity may amplify susceptibility to weight gain via overeating during times of unlimited food access.

Expenditure Reductions Associated with a Social Service Referral Program

Recent health system innovations provide encouraging evidence that greater coordination of medical and social services can improve health outcomes and reduce health care expenditures. This study evaluated the savings associated with a managed care organization's call center-based social service referral program that aimed to assist participants address their social needs, such as homelessness, transportation barriers, and food insecurity. The program evaluation linked social service referral data with health care claims to analyze expenditures in 2 annual periods, before and after the first social service referral. Secondary data analysis estimated the change in mean expenditures over 2 annual periods using generalized estimating equations regression analysis with the identity link. The study compared the change in mean health care expenditures for the second year for those reporting social needs met versus the group whose needs remained unmet. By comparing the difference between the first and second year mean expenditures for both groups, the study estimated the associated savings of social services, after controlling for group differences. These results showed that the decrease in second year mean expenditures for the group of participants who reported all of their social needs met was $2443 (10%) greater than the decrease in second year mean expenditures for the group who reported none of their social needs met, after controlling for group differences. Organizations that integrate medical and social services may thrive under policy initiatives that require financial accountability for the total well-being of patients.

Evaluation of Food Insecurity in Adults and Children With Cystic Fibrosis: Community Case Study

Advances in the care and treatment of cystic fibrosis (CF) have led to improved mortality rates; therefore, considerably more individuals with CF are living into adulthood. With an increased number of CF patients advancing into adulthood, there is the need for more research that surrounds the aging adult CF patient. It is important to conduct research and collect results on the aging CF population to help better prepare the CF patient, who is dealing with the heavy treatment and financial burden of their disease, build autonomy and increase their quality of life. Of note, research has found that social, behavioral, and physical factors influence the ability of those with CF to follow dietary recommendations. A primary treatment goal in CF is a high calorie, high protein, and high fat diet. A socio-economic factor that has not been adequately investigated with regards to dietary compliance of individuals with CF is food insecurity. The aim of this community case study was to document the experiences and estimate the prevalence of food insecurity among CF patients residing in Idaho. The correlation between food insecurity and health outcomes (lung function and body mass index) was also examined. Participants included adult patients and parents of pediatric patients with CF. Food insecurity rates among CF patients of all ages were found to be significantly higher than that seen in the overall community; however, no specific correlation between food insecurity and body mass index (BMI) or lung function emerged. This case study highlights the need for continued research around food access issues in this patient population. The data resulting from this study shows the value of CF advocacy organizations promoting efforts to build resources and provide education around food insecurity issues.

The application of 'valence' to the idea of household food insecurity in Canada

Household food insecurity (HFI), lack of access to adequate food due to financial constraint, has been studied extensively in Canada and is well-recognized for its negative impacts on population health. Despite considerable high-level political recognition, the issue has evoked little substantive policy deliberation. We suggest that Béland and Cox's recently articulated construct of 'valence' may be useful in examining why the idea of HFI has motivated little policy response. Valence is defined as the emotional quality of an idea. According to valence theory, ideas with a high emotional intensity, positive valence acquire importance in policy debate, and those with high intensity, negative valence are 'unthinkable' as a policy idea. We compiled four datasets in which HFI was discussed (verbatim legislative excerpts, parliamentary committee proceedings, government reports, interviews with HFI policy entrepreneurs), representing different kinds of political forums for debate. We analyzed what was said with respect to the valence of the idea of HFI. We found that discussions about HFI were on the whole generally subdued and of low emotional intensity. High intensity negative valence pronouncements were found among legislators' statements and parliamentary committee evidence. Regardless of emotional intensity level, speakers usually talked about the idea of HFI in ways that elicited a negative valence. Positive valence in discussion of the idea of HFI was limited and invoked comments about individual aspiration, prosperity, and community spirit. Our findings suggest that the negative valence of HFI is an inherent trait of the idea that makes it unattractive to policy makers. We suggest that HFI may be a better metric than a policy problem and that aspirational goals with positive valence related to poverty alleviation might better use HFI as an outcome rather than the focus of action.

Prevalence and Predictors of Food Insecurity among Older People in Canada

Background: Food insecurity research has been mainly examined among young people. The root causes of food insecurity are closely linked to poverty, and social policies and income supplements, including public and private pensions, have been shown to sharply curb food insecurity into later life. However, social, economic, and political trends that are closely connected to social and health inequalities threaten to undermine the conditions that have limited food insecurity among older people until now. Exploring the prevalence and predictors of food insecurity among older people across Canada has important implications for domestic policies concerning health, healthcare, and social welfare. Methods: Data come from the Canadian Community Health Survey 2012 Annual Component (n = 14,890). Descriptive statistics and a generalized linear model approach were used to determine prevalence and estimate the associations between food insecurity-as measured by the Household Food Security Survey Module-and social, demographic, geographic, and economic factors. Results: Approximately 2.4% of older Canadians are estimated to be moderately or severely food insecure. Income was by far the strongest predictor of food insecurity (total household income <$20,000 compared to >$60,000, OR: 46.146, 95% CI: 12.523⁻170.041, p < 0.001). Younger older people, and those with a non-white racial background also had significantly greater odds of food insecurity (ages 75+ compared to 65⁻74, OR: 0.322, 95% CI: 0.212⁻0.419, p < 0.001; and OR: 2.429, 95% CI: 1.438⁻4.102, p < 0.001, respectively). Sex, home ownership, marital status, and living arrangement were all found to confound the relationship between household income and food insecurity. Prevalence of food insecurity varied between provinces and territories, and odds of food insecurity were approximately five times greater for older people living in northern Canada as compared to central Canada (OR: 5.189, 95% CI: 2.329⁻11.562, p < 0.001). Conclusion: Disaggregating overall prevalence of food insecurity among older people demonstrates how disparities exist among sub-groups of older people. The seemingly negligible existence of food insecurity among older people has obscured the importance, practicality, and timeliness of including this age group in research on food insecurity. The current research underscores the critical importance of an income floor in preventing food insecurity among older people, and contributes a Canadian profile of the prevalence and predictors of food insecurity among older people to the broader international literature.

Walking the Food Security Tightrope-Exploring the Experiences of Low-to-Middle Income Melbourne Households

There is limited evidence of how Australian low-to-middle income (AUD $40,000⁻$80,000) households maintain food security. Using a sequential explanatory mixed methods methodology, this study explored and compared the food security (FS) and insecurity (FIS) experiences of these households. An initial quantitative survey categorised participants according to food security status (the 18-item United States Department of Agriculture Household Food Security Survey Module) and income level to identify and purposefully select participants to qualitatively explore food insecurity and security experiences. Of the total number of survey participants (n = 134), 42 were categorised as low-to-middle income. Of these, a subset of 16 participants (8 FIS and 8 FS) was selected, and each participant completed an in-depth interview. The interviews explored precursors, strategies to prevent or address food insecurity, and the implications of the experience. Interview data were analysed using a thematic analysis approach. Five themes emerged from the analysis: (i) food decision experiences, (ii) assets, (iii) triggers, (iv) activation of assets, and (v) consequences and emotion related to walking the food security tightrope. The leverage points across all themes were more volatile for FIS participants. Low-to-middle income Australians are facing the challenges of trying to maintain or improve their food security status, with similarities to those described in lower income groups, and should be included in approaches to prevent or address food insecurity.

Inpatient Medicaid Usage and Expenditure Patterns After Changes in Supplemental Nutrition Assistance Program Benefit Levels

Introduction

Food insecurity worsens health outcomes and is associated with increased health care usage and expenditures. The Supplemental Nutrition Assistance Program (SNAP) reduces but does not eliminate recipients’ food insecurity. We sought to determine whether inpatient Medicaid usage and expenditure patterns responded to an April 2009 increase in SNAP benefit levels and a subsequent November 2013 decrease.

Methods

Interrupted time series models estimated responses to the 2009 and 2013 SNAP changes in the Medicaid population, compared responses between Medicaid and Medicare recipients, and compared responses between Medicaid recipients with different likelihoods of having a disability. Analyses used 2006 through 2014 Healthcare Cost and Utilization Project National (previously Nationwide) Inpatient Sample data.

Results

After the 2009 SNAP increase, Medicaid admission growth fell nationally from 0.80 to 0.35 percentage points per month (a difference of –0.45; 95% CI, –0.72 to –0.19), adjusting for enrollment. After the 2013 SNAP decrease, admission growth rose to 2.42 percentage points per month (a difference of 2.07; 95% CI, 0.68 to 3.46). Inflation-adjusted monthly Medicaid expenditures followed similar patterns and were associated with $26.5 billion (in 2006 dollars) in reduced expenditures over the 55 months of the SNAP increase, and $6.4 billion (in 2006 dollars) in additional expenditures over the first 14 months after the SNAP decrease. Effects were elevated for Medicaid compared with Medicare recipients and among people with a high likelihood of having a disability.

Conclusion

Although alternative causal explanations warrant consideration, changes in SNAP benefit levels were associated with changes in inpatient Medicaid usage and cost patterns.

Food insecurity, healthcare utilization, and high cost: a longitudinal cohort study

OBJECTIVES

Reducing utilization of high-cost healthcare services is a common population health goal. Food insecurity-limited access to nutritious food owing to cost-is associated with chronic disease, but its relationship with healthcare utilization is understudied. We tested whether food insecurity is associated with increased emergency department (ED) visits, hospitalizations, and related costs.

STUDY DESIGN

Retrospective analysis of a nationally representative cohort.

METHODS

Adults (≥18 years) completed a food insecurity assessment (using 10 items derived from the US Department of Agriculture Household Food Security Module) in the 2011 National Health Interview Survey and were followed in the 2012-2013 Medical Expenditures Panel Survey. Outcome measures were ED visits, hospitalizations, days hospitalized, and whether participants were in the top 10%, 5%, or 2% of total healthcare expenditures.

RESULTS

Of 11,781 participants, 2056 (weighted percentage, 13.2%) were in food-insecure households. Food insecurity was associated with significantly more ED visits (incidence rate ratio [IRR], 1.47; 95% CI, 1.12-1.93), hospitalizations (IRR, 1.47; 95% CI, 1.14-1.88), and days hospitalized (IRR, 1.54; 95% CI, 1.06-2.24) after adjustment for demographics, education, income, health insurance, region, and rural residence. Food insecurity was also associated with increased odds of being in the top 10% (odds ratio [OR], 1.73; 95% CI, 1.31-2.27), 5% (OR, 2.53; 95% CI, 1.51-3.37), or 2% (OR, 1.95; 95% CI, 1.09-3.49) of healthcare expenditures.

CONCLUSIONS

Food insecurity is associated with higher healthcare use and costs, even accounting for other socioeconomic factors. Whether food insecurity interventions improve healthcare utilization and cost should be tested.

Incremental Health Care Costs Associated With Food Insecurity and Chronic Conditions Among Older Adults

INTRODUCTION

The prevalence of food insecurity and chronic health conditions among older adults is a public health concern. However, little is known about associated health care costs. We estimated the incremental health care costs of food insecurity and selected chronic health conditions among older adults, defined as adults aged 50 or older.

METHODS

We analyzed 4 years of data (2011-2014) from the National Health Interview Survey and 3 years of data (2013-2015) from the Medical Expenditure Panel Survey; we used 2-part models to estimate the incremental health care costs associated with food insecurity and 9 chronic conditions (hypertension, coronary heart disease, stroke, emphysema, asthma, cancer, chronic bronchitis, arthritis, and diabetes) among older adults.

RESULTS

Approximately 14% of older adult respondents (n = 2,150) reported being food insecure. The 3 most common chronic conditions were the same for both food-insecure and food-secure older adults: hypertension, arthritis, and diabetes. The adjusted annual incremental health care costs resulting from food insecurity among older adults were higher in the presence of hypertension, stroke, and arthritis (P ≤ .05) and in the presence of diabetes (P ≤ .10). These findings were also true for the incremental health care costs resulting from food insecurity in the absence of these specific chronic conditions.

CONCLUSION

Our findings show that food insecurity interacts with chronic conditions. We observed higher health care costs in the presence of this interaction for those who were food insecure and had poor health than for those who were food secure.

Food insecurity status and mortality among adults in Ontario, Canada

BACKGROUND

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

METHODS

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

RESULTS

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

INTERPRETATION

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

Public Program Enrollment Following US State Medicaid Expansion and Outreach

OBJECTIVES

To examine the joint impact of states' Medicaid expansion and participation in Medicaid enrollment outreach at the take-up of other means-tested public programs (Women, Infants, and Children [WIC], Supplemental Nutrition Assistance Program [SNAP]).

METHODS

Data were used from the American Community Survey, WIC, and SNAP. We used difference-in-differences analyses to compare the combined impact of Medicaid expansion and enrollment outreach on program enrollment.

RESULTS

Enrollment in means-tested programs decreased after 2014, regardless of Medicaid expansion and outreach status. However, gaps in enrollment among states that both expanded Medicaid and conducted outreach, compared with states that did neither, increased after expansion of SNAP and WIC enrollment (10.15% and 4.57%, respectively) and favored those states that did both.

CONCLUSIONS

States that both expanded Medicaid and conducted Medicaid enrollment outreach experienced smaller decreases in SNAP and WIC enrollment in comparison with other states. Moreover, enrollment in SNAP has shown to reduce health care expenditures. Greater collaboration among public programs, such as streamlining eligibility data and concerted outreach efforts, is one of the achievements of the Affordable Care Act that should be continued.

Food Insecurity and Mental Health among Females in High-Income Countries

Food insecurity is a persistent concern in high-income countries, and has been associated with poor mental health, particularly among females. We conducted a scoping review to characterize the state of the evidence on food insecurity and mental health among women in high-income countries. The research databases PubMed, EMBASE, and psycINFO were searched using keywords capturing food insecurity, mental health, and women. Thirty-nine articles (representing 31 unique studies/surveys) were identified. Three-quarters of the articles drew upon data from a version of the United States Department of Agriculture Household Food Security Survey Module. A range of mental health measures were used, most commonly to measure depression and depressive symptoms, but also anxiety and stress. Most research was cross-sectional and showed associations between depression and food insecurity; longitudinal analyses suggested bidirectional relationships (with food insecurity increasing the risk of depressive symptoms or diagnosis, or depression predicting food insecurity). Several articles focused on vulnerable subgroups, such as pregnant women and mothers, women at risk of homelessness, refugees, and those who had been exposed to violence or substance abuse. Overall, this review supports a link between food insecurity and mental health (and other factors, such as housing circumstances and exposure to violence) among women in high-income countries and underscores the need for comprehensive policies and programs that recognize complex links among public health challenges.
