Household Food Insecurity, Diet Quality, and Obesity: An Explanatory Model

Childhood Food Insecurity Trajectories and Adult Weight and Self-Reported Health

INTRODUCTION

Research has demonstrated that food insecurity during childhood is associated with worse physical and mental health in childhood. However, little is known about how food insecurity during childhood impacts health outcomes in young adulthood.

METHODS

This study analyzed data from the Future of Families and Child Wellbeing Study (2024), a longitudinal birth cohort study of children born in 1998-2000. Childhood food insecurity trajectory groups from age 3 to 15 years were identified using group-based trajectory modeling. Associations between childhood food insecurity trajectory groups and young adult weight (BMI, overweight status, and obese status) and high self-reported health (good/excellent) at age 22 were modeled with multivariate linear and logistic regression.

RESULTS

Three trajectories were identified among 4,296 participants: 66.9% were food secure, 7.5% were food insecure, and 25.6% transitioned from being food insecure-to-secure throughout childhood. In adjusted analyses, young adults assigned to the food insecure-to-secure trajectory group as children had higher BMI (B 0.82, 95% CI [0.07-1.58]) and higher odds of overweight status (OR 1.24, 95% CI [1.01-1.52]) than young adults assigned to the food secure trajectory group as children. Young adults in the food insecure trajectory group as children had lower odds of high self-reported health than those in the food secure trajectory group as children (OR 0.65, 95% CI [0.48-0.89]).

CONCLUSIONS

Food insecurity in childhood is associated with high weight status and poor self-reported health in young adulthood. These findings highlight the importance of childhood food insecurity screening and interventions to promote health throughout the life course.

Understanding the association between household food insecurity and diet quality: The role of psychological distress, food choice motives and meal patterning

Household food insecurity - a lack of reliable access to food that is safe, nutritious, and sufficient for normal growth - is associated with physical and mental ill-health. In the UK and many countries worldwide, food insecurity has been exacerbated by the cost-of-living crisis and is a major public health concern. To identify potential points of intervention, it is important to understand how food insecurity is associated with individual-level factors, including behaviours and motivations towards food. This study therefore examined the associations between household food insecurity (HHFI), psychological distress, motives underlying food choices and meal patterning behaviours in a sample of UK adults (N = 594, mean age = 40.6 years, 96 % female). Key variables were quantified using questionnaires and structural equation modelling was used to determine the associations between them. HHFI was directly associated with higher food choice motives based on price, but not directly with other food choice motives. HHFI was indirectly associated with poorer diet quality via price motives. There were also significant serial indirect associations between HHFI and diet quality via distress and food choice motives. Specifically, HHFI was associated with greater distress, which in turn was associated with higher convenience motives and lower health motives, which were then both associated with poorer diet quality. Exploratory analyses indicated that HHFI was directly associated with lower meal frequency, and this in turn was associated with poorer diet quality. Findings demonstrate how experiences of general psychological distress, certain food choice motives, and meal frequency may play a role in the relationship between food insecurity and diet quality.

Food access and the severity of newly diagnosed pediatric inflammatory bowel disease

OBJECTIVES

Inflammatory bowel disease (IBD) results from genetic susceptibility, gut microbiome, and environmental factors. Diet, one modifiable environmental factor, has been linked to the increased prevalence of IBD. This study aimed to evaluate a potential association between food deserts and disease severity at diagnosis.

METHODS

This retrospective study included newly diagnosed IBD patients (ages of 2 and 21 years of age; diagnosed between January 1, 2019, and December 31, 2021). The United States Department of Agriculture (USDA's) Food Access Research Atlas was used to determine if patients resided in a food desert. The Modified Retail Food Environment Index (mRFEI) determined the ratio of healthy to unhealthy food options. The primary endpoint was disease severity at diagnosis based on endoscopy scores. Statistical analyses were applied as appropriate.

RESULTS

Ninety-eight patients were enrolled (75 [77%] Crohn' disease; 23 [23%] ulcerative colitis), 59 (60%) identified as Non-Hispanic White. Fifteen (15%) patients lived in a food desert. Food deserts consisted of more Black patients than White (67%; p = 0.05), more public insurance (12; 80%), and lower median vitamin D (17.6 [interquartile range (IQR): 10.8-24.]). In an adjusted (sex, age, insurance, race) multivariable model mRFEI was associated with reduced odds of a living in a food desert (0.91 [95% confidence interval (CI): 0.83-0.98]). There was no difference between the severity of disease and living in a food desert or food swamp.

CONCLUSIONS

Fifteen IBD patients lived in a food desert. Food deserts have less access to healthy food retailers and higher rates of unhealthy food retailers. Further work is needed to better understand spatial disparities related to food accessibility and IBD.

Food insecurity amongst universal credit claimants: the benefits and nutrition study (BEANS), a cross-sectional online study

PURPOSE

Increasing food insecurity (FIS) in the UK presents a major challenge to public health. Universal Credit (UC) claimants are disproportionately impacted by FIS but research on socio-demographic factors and consequent nutritional security is limited.

METHODS

A cross-sectional online survey (September 2021 - April 2022) assessed FIS in UC claimants (males and females, n = 328) (USDA 10 question module), dietary intake (females, n = 43; 3-4 × 24-hour dietary recalls) and coping strategies. Binary logistic regression tested sociodemographic variables influencing the odds of food insecurity. Diets ofUC were compared with national diet and nutrition survey (NDNS) participants and thematic analysis conducted for drivers and impacts of FIS.

RESULTS

FIS was experienced by 84.8% of UC respondents (73.8% very low food security). Equivalised income <£200 week-1 increased odds of FIS by 7.3 (3.4-15.3) times compared with households receiving >£300 week-1. Being unemployed (P = 0.004), travelling > 15 min to obtain food (P = 0.016), shopping less than twice per week (P = 0.001) and receiving < 47.7% of the minimum income standard (MIS) all increased risk of FIS. Diet quality of working age females was lower (45.9%) compared to those in the NDNS (49.6-55.8%; P < 0.05) characterised by limited protein sources, minimal fruit consumption and reliance on bread. Intakes of vitamin A, iron, selenium, potassium, iodine and magnesium were consistently below most NDNS cohorts. Participants felt impotent to make substantive changes to their diets due to poverty.

CONCLUSION

During this study, dependence on UC almost guaranteed recipients would be food insecure, consuming insufficient micronutrients to support health. MIS may provide a useful benchmark to prevent food poverty.

Influential Attributes on Medical Expense for Korean Older Adults Based on Mental Accounting: Panel Data Analysis Using Korean Longitudinal Study of Aging Data

Backgrounds: Korean society is entering an aging society, and this phenomenon indicates the need for preparation for aging in Korean society. In such a situation, exploring the characteristics of the elderly can be considered important for preparation. The objective of this study is to identify the determinants of medical expenses among older adults in South Korea. The key factors analyzed include food, leisure, and housing expenses, as well as lifestyle choices such as drinking and smoking. Method: Data from the Korean Longitudinal Study of Aging, covering 7374 observations from the years 2018 and 2020, are adopted for statistical analysis. This research explores the inverted-U-shape effect of food, leisure, and housing expenditures on medical costs, grounded in the concepts of diminishing marginal utility and mental accounting. A quadratic panel regression analysis is used to test the hypotheses, controlling for variables such as birth year, gender, and personal assets. Results: The results show that food and housing expenses have an inverted-U relationship with medical expenditures based on diminishing marginal utility and mental accounting as the theoretical foundation. However, leisure expenses, drinking, and smoking do not significantly affect medical expenses. Furthermore, this study identifies the optimal expenditure levels for maximizing medical spending through the first-order condition. Conclusions: These findings provide important insights for the development of policies aimed at improving the financial well-being of older adults in South Korea. Moreover, this study contributes to the literature by applying the concepts of mental accounting and the law of diminishing marginal utility to better understand the financial behavior of older adults.

Investigating the mediating role of physical activity within the association between food insecurity and BMI

Food insecurity is linked with obesity and while the mechanisms behind this association are complex, lower levels of leisure-time physical activity in those with food insecurity may contribute to this. Individual-level factors (such as concerns of performing physical activity) may partly determine levels of physical activity within individuals with food insecurity, as such individuals may seek to minimise their levels of physical activity in order to preserve energy. Using the Food Insecurity Physical Activity Concerns Scale (FIPACS) (used to measure concerns of performing leisure-time physical activity, focusing on factors specific to food insecurity), the current study investigated whether the association between household food insecurity and body mass index (BMI) is explained by a mediation pathway of FIPACS scores and leisure-time physical activity. We also investigated whether the association between food insecurity and FIPACS scores is moderated by nutrition knowledge. Participants (N = 329, food insecure = 55) completed an online survey consisting of the FIPACS, the International Physical Activity Questionnaire long-form (IPAQ), the Diet, Disease, and Weight management sub-section of the General Nutrition Knowledge Questionnaire, a measure of diet quality, and self-reported BMI. Findings revealed that FIPACS scores and leisure-time physical activity did not mediate the association between food insecurity and BMI (b < 0.01, SE = 0.01). Additionally, nutrition knowledge did not moderate the association between food insecurity and FIPACS scores (b = -0.09, SE = 0.08). Findings suggest that concerns of performing physical activity in the context of food insecurity are unrelated to leisure-time physical activity, and that these two factors do not explain the association between food insecurity and BMI. Future research should investigate other factors in the link between food insecurity, physical activity, and BMI.

Mortality from type 2 diabetes mellitus across municipalities in Mexico

BACKGROUND

One in six Mexican adults' lives with type 2 diabetes mellitus (T2DM), which is the third leading cause of death in the country. Analyzing the geographic distribution of T2DM mortality helps identify regions with higher mortality rates. This study aimed to examine the spatial patterns of mortality from type 2 diabetes mellitus (T2DM) across municipalities in Mexico and to analyze the main contextual factors linked to this cause of death in 2020.

METHODS

We employed a spatial Bayesian hierarchical regression model to estimate the risk and probability of death from type 2 diabetes mellitus (T2DM) across Mexico's municipalities.

RESULTS

The SMR results revealed geographic and age-specific patterns. Central Mexico and the Yucatán Peninsula exhibited the highest excess mortality rates. For the population under 50 years of age, municipalities in Oaxaca had the highest T2DM mortality rates, whereas those aged 50 years old and older had the highest rates in Tlaxcala and Puebla. Socioeconomic factors such as low levels of educational attainment, lack of health services, dietary deficiency, and marginalization were positively associated with increased T2DM mortality risk. By contrast, GDP per capita showed a negative association. High-risk areas for T2DM mortality were prominent along the south of the Pacific Coast, the Bajío, Central Mexico, and southern Yucatán for those under 50, and along a central strip extending to the Yucatán Peninsula for the older population. Significant uncertainties in mortality risk were identified, with Central Mexico, Oaxaca, Chiapas, and Tabasco showing high probabilities of excess risk for those under 50 years of age and extended risk areas along the Gulf of Mexico for those 50 years old and older.

CONCLUSIONS

The assessment and identification of spatial distribution patterns associated with T2DM mortality, and its main contextual factors, are crucial for informing effective public health policies aimed at reducing the impact of this chronic disease in Mexico.

Food insecurity and other barriers to adherence to a gluten-free diet in individuals with coeliac disease and non-coeliac gluten sensitivity in the Netherlands: a mixed-methods study

OBJECTIVES

To determine the prevalence of food insecurity among individuals with coeliac disease (CeD) and non-coeliac gluten sensitivity (NCGS) in the Netherlands and explore its association with diet quality and other barriers to adherence to a gluten-free diet.

DESIGN

Mixed-method design comprising a survey and semistructured interviews.

SETTING

An online survey was distributed through social media accounts and the newsletter of the Dutch Association for Celiac Disease. Community-dwelling patients were surveyed and interviewed between June and November 2023.

PARTICIPANTS AND OUTCOME MEASURES

In total 548 adults with CeD and NCGS in the Netherlands who adhered to a gluten-free diet completed the survey including questions related to demographics, household food insecurity, financial stress and diet quality. Regression analyses were conducted to assess associations between food insecurity and diet quality, and between food insecurity and perceived difficulty of gluten-free eating and cooking. Additionally, semistructured interviews with eight food insecure adults with CeD were conducted.

RESULTS

The prevalence of food insecurity was 23.2%, with 10.4% reporting very low food security. Very low food insecurity was associated with poorer diet quality (β=-5.5; 95% CI=-9.2 to -1.9; p=0.003). Food insecurity was associated with heightened perceived barriers across multiple themes. In age, income and education adjusted models, compared with food secure participants, low food secure participants were more likely to experience difficulty regarding skills (OR=2.5; 95% CI=1.5 to 4.3; p≤0.001), social circumstances (OR=2.6; 95% CI=1.1 to 6.4; p=0.038), resources (OR=2.5; 95% CI=1.5 to 4.4; p=0.001) and naturally gluten-free products (OR=1.8; 95% CI=1.0 to 3.1; p=0.045) in gluten-free eating and cooking. Participants with very low food security were more likely to experience difficulty regarding skills (OR=4.4; 95% CI=2.4 to 8.1; p≤0.001) and resources (OR=4.2; 95% CI=2.3 to 7.8; p<0.001) in gluten-free eating and cooking. The qualitative analysis provided a deeper understanding of these challenges, including employed strategies to manage costs and insights into the mental burden associated with adhering to a gluten-free diet.

CONCLUSION

These findings indicate that food insecurity is prevalent among Dutch people with CeD and NCGS, with potential impact on diet quality and adherence to a gluten-free diet. It further provided insight into perceived barriers to adhering to a gluten-free diet among this target population. These challenges should be taken into account by clinicians and policy makers.

The impact of food aid interventions on food insecurity, diet quality and mental health in households with children in high-income countries: a systematic review

OBJECTIVE

Households with children accessing food aid in high-income countries are often food insecure. We aimed to review the evidence on food aid interventions in households with children and impact on food insecurity, diet quality and mental health.

DESIGN

A systematic search was conducted using Web of Science, MEDLINE, CINAHL and PsycINFO. Articles published from January 2008 to July 2022 including cross-sectional, cohort and interventional studies in high-income countries were eligible.

SETTING

Food aid is defined as the use of interventions providing free food items by community and/or charitable organisations.

PARTICIPANTS

Two-parent, lone parent or households with a primary caregiver with at least one child ≤ 18 years.

RESULTS

From a total of 10 394 articles, nine were included. Food banks, mobile pantry combined with a free meal for children, backpack provision during school term and food parcel home delivery interventions were evaluated. Food bank models offering additional support such as community programmes, health and social services, cooking classes and free meals for children, client-choice-based models and programmes providing convenient access were associated with improved food security and diet quality (increased intake of wholegrains, fruit and vegetables). One study reported an improvement in mental health and food bank access at the end of 18 months but not at earlier timepoints and one study reported no change in parents' mental health.

CONCLUSIONS

Accessing food aid was linked to improved diet quality and reduced food insecurity in some studies. Allowing clients to choose food items and providing support services were most effective.

Food inequity and insecurity and MASLD: burden, challenges, and interventions

Liver disease prevalence, severity, outcomes and hepatic risk factors (for example, unhealthy diet) are heavily affected by socioeconomic status and food insecurity. Metabolic dysfunction-associated steatotic liver disease (MASLD) is the most prevalent liver disease globally and is likely to co-occur with other liver diseases associated with food insecurity. Though weight reduction and adopting a healthy diet can reverse the course of MASLD, gaps between recommendations and practice transcend individual responsibility and preference. Broader sociocultural determinants of food choices (social nutrition) include food insecurity, community and social norms and the local environment, including commercial pressures that target people experiencing poverty, ethnic minorities and children. Food insecurity is a barrier to a healthy diet, as a low-quality diet is often less expensive than a healthy one. Consequently, food insecurity is an 'upstream' risk factor for MASLD, advanced fibrosis and greater all-cause mortality among patients with liver disease. Intervening on food insecurity at four major levels (environment, policy, community and health care) can reduce the burden of liver disease, thereby reducing social and health inequities. In this Review, we report on the current research in the field, the need for implementing proven interventions, and the role liver specialists can have.

Associations between food insecurity in high-income countries and pregnancy outcomes: A systematic review and meta-analysis

BACKGROUND

Maternal nutrition is crucial for health in pregnancy and across the generations. Experiencing food insecurity during pregnancy is a driver of inequalities in maternal diet with potential maternal and infant health consequences. This systematic review explored associations between food insecurity in pregnancy and maternal and infant health outcomes.

METHODS AND FINDINGS

Searches included 8 databases (MEDLINE, Embase, Scopus, Web of Science, PsychInfo, ASSIA, SSPC in ProQuest, and CINAHL), grey literature, forwards and backwards citation chaining, and contacting authors. Studies in high-income countries (HICs) reporting data on food insecurity in pregnancy and maternal or infant health, from January 1, 2008 to November 21, 2023 were included. Screening, data extraction, and quality assessment were carried out independently in duplicate. Random effects meta-analysis was performed when data were suitable for pooling, otherwise narrative synthesis was conducted. The protocol was registered on PROSPERO (CRD42022311669), reported with PRISMA checklist (S1 File). Searches identified 24,223 results and 25 studies (n = 93,871 women) were included: 23 from North America and 2 from Europe. Meta-analysis showed that food insecurity was associated with high stress level (OR 4.07, 95% CI [1.22, 13.55], I2 96.40%), mood disorder (OR 2.53, 95% CI [1.46, 4.39], I2 55.62%), gestational diabetes (OR 1.64, 95% CI [1.37, 1.95], I2 0.00%), but not cesarean delivery (OR 1.42, 95% CI [0.78, 2.60], I2 56.35%), birth weight (MD -58.26 g, 95% CI [-128.02, 11.50], I2 38.41%), small-for-gestational-age (OR 1.20, 95%, CI [0.88, 1.63], I2 44.66%), large-for-gestational-age (OR 0.88, 95% CI [0.70, 1.12] I2 11.93%), preterm delivery (OR 1.18, 95% CI [0.98, 1.42], I2 0.00%), or neonatal intensive care (OR 2.01, 95% CI [0.85, 4.78], I2 70.48%). Narrative synthesis showed food insecurity was significantly associated with dental problems, depression, anxiety, and maternal serum concentration of perfluoro-octane sulfonate. There were no significant associations with other organohalogen chemicals, assisted delivery, postpartum haemorrhage, hospital admissions, length of stay, congenital anomalies, or neonatal morbidity. Mixed associations were reported for preeclampsia, hypertension, and community/resilience measures.

CONCLUSIONS

Maternal food insecurity is associated with some adverse pregnancy outcomes, particularly mental health and gestational diabetes. Most included studies were conducted in North America, primarily the United States of America, highlighting a research gap across other contexts. Further research in other HICs is needed to understand these associations within varied contexts, such as those without embedded interventions in place, to help inform policy and care requirements.

The association between COVID-19 related income loss and diet quality: The mediating role of distress

The COVID-19 lockdowns saw many individuals lose income, experience distress and increase intake of foods that would typically be considered less 'healthy' (more processed and less fresh produce). Establishing whether there are direct and indirect links between these variables would be of benefit in preparing for similar future events but also has implications for the current global financial climate, where many are experiencing relative decreases in income. Adults in two locations (UK and Australia) (N = 917) completed online questionnaires to explore the impact of the first COVID-19 lockdown on their change in income, emotional wellbeing (depression, anxiety, stress, loneliness), resilience and diet quality. A structural equation model revealed that income loss was indirectly associated with diet quality via distress. As such, the greater the loss of income experienced, the more distress reported; distress was then directly associated with a less nutritious diet. This pattern of results existed when data from both countries were combined but also when they were modelled individually. Our findings indicate that where individuals experience a sudden reduction of income there are likely to be negative consequences for both mental and physical health. It is plausible that these findings would extend to other circumstances in which sudden loss of income may be experienced such as reductions in state social care, rising inflation and interest rates and sudden increases to the general cost of living.

Physician Perspectives on Malnutrition Screening, Diagnosis, and Management: A Qualitative Analysis

Malnutrition is an important clinical entity that is frequently underdiagnosed and undertreated, in part due to a lack of education and different perceptions by healthcare providers on its value in medical practice. Given this void, the purpose of this qualitative study was to explore physicians' clinical perspectives on malnutrition care, including its prevalence in their practice, and potential barriers that might preclude the delivery of malnutrition care. Using a directed content qualitative analysis approach, a total of 22 general and subspecialist physicians across three Canadian provinces were interviewed using a series of standardized questions developed by a multidisciplinary research team. Responses were transcribed and then analyzed using NVivo Version 14 software. While physicians recognized the importance of malnutrition screening and treatment, they did not view themselves as the primary drivers and often deferred this responsibility to dietitians. Lack of standard malnutrition screening, education amongst allied healthcare providers, time, personnel, and referral processes to have patients assessed and managed for malnutrition were also identified as contributing factors. For physicians, malnutrition education, standard malnutrition screening during patient encounters, and access to the necessary tools to manage malnutrition using a more centralized approach and standard referral process were viewed as strategies with the potential to improve the ability of the physician to identify and manage disease-related malnutrition and its negative consequences.

Associated factors of diet quality among people living with HIV/AIDS in Ghana

INTRODUCTION

Nutrition is a very important element of a comprehensive care for people living with HIV/AIDS (PLHIV), especially in resource-constrained settings where malnutrition and food insecurity are common. Dietary diversity is a useful indication of nutritional adequacy (diet quality) in people of all ages. An optimally diverse diet strengthens the body's immune system.

OBJECTIVE

This study aimed to assess diet quality and its associated factors among PLHIV.

METHODS

A facility-based cross-sectional study design was employed to select 440 PLHIV from two hospitals in the Eastern Region of Ghana. Dietary intakes were determined using 24-hour recall. A stadiometer and bioimpedance analysis machine were used to obtain anthropometric and body composition data. Diet quality was assessed using FAO's individual dietary diversity score (IDDS) as a proxy. SPSS version 20 was used for analysis. Odds ratios and ordinal logistic regression were used to identify factors associated with diet quality among the PLHIV. P-value was set at 0.05.

RESULTS

Most of the PLHIV (73%) consumed from 'Starchy staple" food group. Less than 20% of the study sample consumed 'Fruits' and 'Vegetables' (17% and 14% respectively) a day before the survey. The mean IDDS was 4.11 (SD = 1.29). Overall, most of the PLHIV (56%) had medium IDDS which is equivalent to "diet needing improvement', 14% had higher IDDS (good diet), whiles about 31% of the participants actually had poor diet (lower IDDS). Associated factors of diet quality were age (AOR = 0.966: 95%CI: 0.936-0.997: p = 0.031), married (AOR = 4.634: 95%CI: 1.329-16.157: p = 0.0016), separated (AOR = 0.0203: 95%CI: .036-0.994: p = 0.049), and daily meal frequency (AOR = 0.441: 95%CI: .478-1.948: p = 0.020). Overall, the model accounts for about 20% of the variation in diet quality of the participants (pseudo-R square = 0.196).

CONCLUSION

This study demonstrates that most of the PLHIV did not consume good diet which may have an implication on their immune system, which is already under attack by HIV, and probably emerging infections. Age, marital status, and meal frequency were the variables that predicted diet quality among the study participants.

The lived experience of food insecurity among adults with obesity: a quantitative and qualitative systematic review

BACKGROUND

Food insecurity and obesity are increasing both globally and in the UK. In this review we systematically assess the lived experiences of people with obesity who are food insecure and often turn to food banks.

METHODS

We systematically searched electronic databases from January 2007 until October 2022. Data from eligible studies were extracted and the studies assessed for quality. Thematic analysis and narrative synthesis approach was used to analyse the extracted data.

RESULTS

Six themes were identified among 25 included studies, including: the financial cost of food; psychological aspects related to food insecurity; geographical access and the food environment; food practices in the home; experience of food assistance; and parental-child relationships. The cost of healthy food and psychological factors were identified as key driving factors of the relationship between food insecurity and obesity. Psychological factors such as depression, low self-esteem and stress played an important part in the lived experience of people with obesity and food insecurity.

CONCLUSION

The food environment provides context in which food decisions are made, therefore, systems change is necessary to ensure families can afford the food that enables a healthy diet. For clinicians, identification, and attention to the impact of food insecurity on people with obesity are important.

The impact of the cost of living crisis and food insecurity on food purchasing behaviours and food preparation practices in people living with obesity

Lower income households are at greater risk of food insecurity and poor diet quality than higher income households. In high-income countries, food insecurity is associated with high levels of obesity, and in the UK specifically, the cost of living crisis (i.e., where the cost of everyday essentials has increased quicker than wages) is likely to have exacerbated existing dietary inequalities. There is currently a lack of understanding of the impact of the current UK cost of living crisis on food purchasing and food preparation practices of people living with obesity (PLWO) and food insecurity, however this knowledge is critical in order to develop effective prevention and treatment approaches to reducing dietary inequalities. Using an online survey (N = 583) of adults residing in England or Scotland with a body mass index (BMI) of ≥30 kg/m2, participants self-reported on food insecurity, diet quality, perceived impact of the cost of living crisis, and their responses to this in terms of food purchasing behaviours and food preparation practices. Regression analyses found that participants adversely impacted by the cost of living crisis reported experiencing food insecurity. Additionally, food insecurity was associated with use of specific purchasing behaviours (i.e., use of budgeting, use of supermarket offers) and food preparation practices (i.e., use of energy-saving appliances, use of resourcefulness). Exploratory analyses indicated that participants adversely impacted by the cost of living crisis and who used budgeting had low diet quality, whereas use of meal planning was associated with high diet quality. These findings highlight the fragility of food budgets and the coping strategies used by PLWO and food insecurity during the cost of living crisis. Policy measures and interventions are urgently needed that address the underlying economic factors contributing to food insecurity, to improve access to and affordability of healthier foods for all.

Diet in Food Insecurity: A Mediator of Metabolic Health?

Objective

Food insecurity (FI) is associated with poor metabolic health. It is assumed that energy intake and diet quality underlie this association. We tested the hypothesis that dietary factors (quantity and quality) mediate the association of FI with excess weight, waist circumference and glycemic control [glycohemoglobin (A1C)].

Methods

A mediation analysis was performed on data from the National Health And Nutrition Examination Survey using FI as an independent variable; body mass index (BMI), waist circumference, and A1C as metabolic outcome variables and total energy intake, macronutrients, and diet quality measured by the Healthy Eating Index-2015 (HEI-2015) as potential mediators.

Results

Despite a greater prevalence of obesity in participants experiencing FI, daily reported energy intake was similar in food-secure and -insecure subjects. In adjusted analyses of the overall cohort, none of the examined dietary factors mediated associations between FI and metabolic outcomes. In race-stratified analyses, total sugar consumption was a partial mediator of BMI in non-Hispanic Whites, while diet quality measures (HEI-2015 total score and added sugar subscore) were partial mediators of waist circumference and BMI, respectively, for those in the "other" ethnic group.

Conclusion

Dietary factors are not the main factors underlying the association of FI with metabolic health. Future studies should investigate whether other social determinants of health commonly present in the context of FI play a role in this association.

The relationship between household food insecurity and overweight or obesity among children and adults in Canada: a population-based, propensity score weighting analysis

Household food insecurity is independently associated with adverse health outcomes among Canadians, but its association with overweight and obesity is poorly understood partly because of limited attention to confounding. This study assessed the relationship between food insecurity status and overweight/obesity in Canada. Cross-sectional data for individuals aged 2-64 years were drawn from the 2004 and 2015 Canadian Community Health Survey-Nutrition. Overweight/obesity was defined using body mass index calculated with measured height and weight. Food insecurity status was assessed with the 18-item Household Food Security Survey Module. The relationship was examined among preschool children (n = 2007), girls (n = 5512), boys (n = 5507), women (n = 8317), and men (n = 7279) using propensity score weighted logistic regressions to control for confounding. Relative to their food-secure counterparts, girls in moderately food-insecure households (39.7% vs. 28.5%), boys in severely food-insecure households (54.4% vs. 35.0%), and women in moderately and severely food-insecure households (58.9% and 73.1% vs. 50.7%) had higher overweight/obesity prevalence; men in moderately food-insecure households had a lower prevalence (48.9% vs. 66.3%). With propensity score weighting, no association existed between food insecurity and overweight/obesity among preschool children, girls, boys, or men. For women, moderate (adjusted odds ratio (AOR): 1.61; 95% confidence interval (95%CI): 1.06-2.47) and severe (AOR: 2.33; 95%CI: 1.22-4.44) food insecurity was positively associated with overweight/obesity; the association was strongest for severe food insecurity and obesity (AOR: 3.38; 95%CI: 1.60-7.16). Additional research is needed to better understand the nature of the relationship among women. Problems of food insecurity and overweight/obesity among Canadian children and men should not be conflated in public health interventions.

Food insecurity and its association with multiple health outcomes among Indigenous peoples in Canada: the buffering role of culture-based resources

OBJECTIVES

Despite growing interest in the health disparities associated with food insecurity, research focusing on Indigenous peoples has been limited, especially in studies using nationally representative samples. This study investigates the association between food insecurity and various health outcomes - self-rated general and mental health, chronic health conditions, suicidal ideation, and obesity - among Indigenous peoples in Canada. It also explores the potential moderating effects of culture-based resources, which include cultural identity affect, cultural group belonging, cultural engagement, and cultural exploration.

DESIGN

The study utilized data from the 2017 Aboriginal Peoples Survey, a nationally representative sample of First Nations individuals living off-reserve, Métis, and Inuit across Canada (N = 15,533). Logistic regression models were used to analyze the data.

RESULTS

Food insecurity was negatively associated with all examined health outcomes. Culture-based resources demonstrated a mixture of anticipated and unexpected effects on these relationships. Consistent with the stress process model, cultural group belonging mitigated the negative impact of food insecurity on all health outcomes. A similar pattern was observed for cultural engagement. However, contrary to expectations from the stress-buffering perspective, little evidence was found to support the moderating effects of cultural identity affect and cultural exploration.

CONCLUSION

The results underscore the detrimental effects of food insecurity on the health of Indigenous peoples in Canada and suggest that culture-based resources, particularly cultural group belonging, play a crucial role in mitigating health disparities.

Experimental biology can inform our understanding of food insecurity

Food insecurity is a major public health issue. Millions of households worldwide have intermittent and unpredictable access to food and this experience is associated with greater risk for a host of negative health outcomes. While food insecurity is a contemporary concern, we can understand its effects better if we acknowledge that there are ancient biological programs that evolved to respond to the experience of food scarcity and uncertainty, and they may be particularly sensitive to food insecurity during development. Support for this conjecture comes from common findings in several recent animal studies that have modeled insecurity by manipulating predictability of food access in various ways. Using different experimental paradigms in different species, these studies have shown that experience of insecure access to food can lead to changes in weight, motivation and cognition. Some of these studies account for changes in weight through changes in metabolism, while others observe increases in feeding and motivation to work for food. It has been proposed that weight gain is an adaptive response to the experience of food insecurity as 'insurance' in an uncertain future, while changes in motivation and cognition may reflect strategic adjustments in foraging behavior. Animal studies also offer the opportunity to make in-depth controlled studies of mechanisms and behavior. So far, there is evidence that the experience of food insecurity can impact metabolic efficiency, reproductive capacity and dopamine neuron synapses. Further work on behavior, the central and peripheral nervous system, the gut and liver, along with variation in age of exposure, will be needed to better understand the full body impacts of food insecurity at different stages of development.

The qualitative evaluation of food addiction across the lifespan

Although it remains controversial, food addiction (FA) research has expanded substantially and empirical evidence for FA is growing. While quantitative studies have explored the prevalence and correlates of FA during childhood and adolescence, little is known about the perceived lived experience of FA across the lifespan, nor how experiences and perceptions of FA may change over time. For this study, 16 participants who met symptom threshold criteria for FA on the Yale Food Addiction Scale 2.0 completed in-depth, semi-structured qualitative interviews focused on their perceptions of the development of FA overtime, and perceived risk and protective factors. Thematic analysis was used to develop themes about the lived experience of FA in childhood, adolescence, and adulthood. Overall, highly palatable foods were viewed as the most problematic, while minimally processed foods were less associated with impairment and distress. Themes in childhood included a strong desire for highly processed foods and the perception that parental control over food choices could be either protective or risky for the later development of FA depending on which foods were available at home. In adolescence and young adulthood, increasing autonomy over food choices and the high availability of highly processed foods in the college environment were viewed as risk factors. Additionally, weight gain was a prominent theme. Finally, adulthood was characterized by more severe manifestations of FA, and the stress of adult responsibilities (e.g., work, parenting) contributed to this perception. This research sets the stage for future quantitative studies to explore these novel findings at the population level.

The Association of Preoperative Food Insecurity With Early Postoperative Outcomes After Bariatric Surgery

INTRODUCTION

To assess the rate of food insecurity in patients undergoing bariatric surgery. To compare the rates of 30-d postoperative complications based on food security status.

METHODS

Patients undergoing primary Roux-en-Y gastric bypass or sleeve gastrectomy between 7/2020 - 3/2022 were screened for food insecurity via telephone using questions from the Accountable Health Communities Health-Related Social Needs Screening Tool. Screens were matched to patient data and 30-d outcomes from the Metabolic and Bariatric Surgery Accreditation and Quality Improvement Program database.

RESULTS

In total, 213 (59%) of the 359 bariatric surgery patients were screened with 81 (38%) screening positive for food insecurity. Evaluation of preoperative variables based on food security status showed comparable age, body mass index, and comorbidity status. Food insecure patients were found to have an increased length of stay following surgery compared to food secure patients (P = 0.003). Food insecurity was not associated with higher rates of Metabolic and Bariatric Surgery Accreditation and Quality Improvement Program reported 30-d postoperative complications including emergency department/urgent care visits (P = 0.34) and hospital readmissions (P = 0.94).

CONCLUSIONS

Food insecurity was prevalent at 38% of the bariatric surgical population. Food insecure patients had a statistically longer length of stay after primary bariatric surgery but were not associated with an increased risk of 30-d complications. Future studies are needed to determine the mid-term and long-term effects of food insecurity status on bariatric surgical outcomes and the potential impact of food insecurity on length of stay.

A positive association between food insecurity and the prevalence of overactive bladder in U.S. adults

Objective

This study aims to examine the correlation between overactive bladder (OAB) and food insecurity.

Methods

We conducted a cross-sectional analysis utilizing extensive population data derived from the National Health and Nutrition Examination Survey 2007-2018. The status of Household food insecurity is evaluated by the US Food Security Survey Module. To explore the relationship between food insecurity and OAB, three multivariable logistic regression models were carried out. Additionally, interaction and stratified analyses were also performed to find whether some factors have the potential to alter the correlation.

Results

There were 29,129 participants enrolled in the study. Compared to the other three groups, individuals with full food security exhibited a lower proportion of nocturia, urinary urgency incontinence, and OAB. In the fully-adjusted model, it was found that people experiencing food insecurity have a significantly higher prevalence of OAB compared to those with food security in the fully-adjusted model (OR = 1.540, 95%CI 1.359-1.745). Additionally, there was a significant association between the levels of food insecurity and an increased risk of OAB prevalence was also observed (marginal food security: OR = 1.312, low food security: OR = 1.559, and very low food security: OR = 1.759). No significant interaction was seen in the fully-adjusted model.

Conclusion

There is a strong positive correlation between food insecurity and the prevalence of OAB. Similarly, the correlation between levels of food insecurity and OAB also indicates the same trend. Namely, the more insecure food, the higher risk of OAB prevalence in the population.

Lifestyle interventions in nonalcoholic fatty liver disease

Nonalcoholic fatty liver disease (NAFLD) is a dynamic chronic liver disease that develops in close association with metabolic irregularities. Between 2016 and 2019, the global prevalence among adults was reported as 38% and among children and adolescents it was about 10%. NAFLD can be progressive and is associated with increased mortality from cardiovascular disease, extrahepatic cancers and liver complications. Despite these numerous adverse outcomes, no pharmacological treatments currently exist to treat nonalcoholic steatohepatitis, the progressive form of NAFLD. Therefore, the main treatment is the pursuit of a healthy lifestyle for both children and adults, which includes a diet rich in fruits, nuts, seeds, whole grains, fish and chicken and avoiding overconsumption of ultra-processed food, red meat, sugar-sweetened beverages and foods cooked at high heat. Physical activity at a level where one can talk but not sing is also recommended, including leisure-time activities and structured exercise. Avoidance of smoking and alcohol is also recommended. Policy-makers, community and school leaders need to work together to make their environments healthy by developing walkable and safe spaces with food stores stocked with culturally appropriate and healthy food items at affordable prices as well as providing age-appropriate and safe play areas in both schools and neighbourhoods.

Food insecurity is associated with lower diet quality among dental students

PURPOSE

Food insecurity is associated with lower diet quality, adverse health outcomes, and academic difficulty among undergraduate students. The objective was to identify the relationship between food security status and diet quality in dental students.

METHODS

All dental students attending Howard University (n = 286) or the University of Iowa (n = 326) during the fall 2021 semester were invited to complete a cross-sectional survey designed to query demographics, food security status (i.e., United States Department of Agriculture's ten item Adult Food Security Module), and diet quality (i.e., short Healthy Eating Index). The survey was administered using the Qualtrics platform.

RESULTS

Response rates were similar for Howard (32.5%) and Iowa (29.4%). Students with food insecurity (46.0%) were slightly older and more likely to be Black or other, first generation professional/graduate students, and receive financial aid than peers with food security (p < 0.050). Food insecurity was associated with lower intakes of fruits and vegetables (p ≤ 0.005), higher intakes of added sugars (p < 0.001), and lower diet quality (p = 0.003). In linear regression analyses that controlled for other variables, food insecurity (p = 0.012), school site (p = 0.027), and gender (p = 0.039) were predictive of lower diet quality.

CONCLUSIONS

The inability to procure adequate and appropriate foods was associated with marginal dietary habits (i.e., less than ideal food choices and eating behaviors) and lower diet quality in dental students. Both marginal dietary habits and lower diet quality increase chronic disease risk and may present a barrier to academic success. Addressing food insecurity among dental students is necessary to ensure equitable opportunities for a healthy workforce in the future.

Food Is Medicine: A Presidential Advisory From the American Heart Association

Unhealthy diets are a major impediment to achieving a healthier population in the United States. Although there is a relatively clear sense of what constitutes a healthy diet, most of the US population does not eat healthy food at rates consistent with the recommended clinical guidelines. An abundance of barriers, including food and nutrition insecurity, how food is marketed and advertised, access to and affordability of healthy foods, and behavioral challenges such as a focus on immediate versus delayed gratification, stand in the way of healthier dietary patterns for many Americans. Food Is Medicine may be defined as the provision of healthy food resources to prevent, manage, or treat specific clinical conditions in coordination with the health care sector. Although the field has promise, relatively few studies have been conducted with designs that provide strong evidence of associations between Food Is Medicine interventions and health outcomes or health costs. Much work needs to be done to create a stronger body of evidence that convincingly demonstrates the effectiveness and cost-effectiveness of different types of Food Is Medicine interventions. An estimated 90% of the $4.3 trillion annual cost of health care in the United States is spent on medical care for chronic disease. For many of these diseases, diet is a major risk factor, so even modest improvements in diet could have a significant impact. This presidential advisory offers an overview of the state of the field of Food Is Medicine and a road map for a new research initiative that strategically approaches the outstanding questions in the field while prioritizing a human-centered design approach to achieve high rates of patient engagement and sustained behavior change. This will ideally happen in the context of broader efforts to use a health equity-centered approach to enhance the ways in which our food system and related policies support improvements in health.

The Impact of COVID-19 Restrictions and Changes to Takeaway Regulations in England on Consumers' Intake and Methods of Accessing Out-of-Home Foods: A Longitudinal, Mixed-Methods Study

BACKGROUND

COVID-19 restrictions significantly impacted the operations of fast food and full-service retailers. Full-service retailers were permitted to operate as takeaway outlets without needing to seek formal changes in planning permissions. We conducted a study to determine consumers' intake and modes of accessing foods from fast food and full-service retailers during various COVID-19 restrictions and changes to takeaway/delivery regulations, as well as their experiences.

METHODS

We conducted a longitudinal, mixed-methods study comprising three surveys, which examined the intake frequency and modes of accessing retailers, and two rounds of qualitative focus groups, which explored their related experiences. The data were collected at three timepoints (T) from May 2021-March 2022. The participants were adults living in Northern England (n = 701 at T1); a sub-sample participated in the focus groups (n = 22). The intake data were presented descriptively; an ordered logit regression explored the factors associated with the intake frequency. The focus group data were analysed using a framework analysis.

RESULTS

The mean weekly intake frequency from fast food retailers at T1, T2, and T3 was 0.96 (SD 1.05), 1.08 (SD 1.16), and 1.06 times (SD 1.12), respectively. For full-service retailers, this was 0.36 (SD 0.69), 0.75 (1.06), and 0.71 (SD 0.99) times, respectively. Food access issues (OR (SE): T1 = 1.65 (0.40), T2 = 2.60 (0.66), T = 2.1 (0.62)) and obesity (T1 = 1.61 (0.31), T2 = 2.21 (0.46), T3 = 1.85 (0.42)) were positively associated with intake from fast food, but not full-service retailers. Delivery services were commonly used to access fast food (30-34% participants), but not full-service retailers (6-10% participants). As COVID-19 restrictions eased, participants were eager to socialise on-premises at full-service retailers.

CONCLUSIONS

Takeaway/delivery services were seldom used to access full-service retailers, but the use of delivery services to access fast food was high. Policymakers must recognise delivery services as a growing part of the food environment, and the challenges they pose to planning policies for obesity prevention.

Diet and Food and Nutrition Insecurity and Cardiometabolic Disease

Poor nutrition is the leading cause of poor health, health care spending, and lost productivity in the United States and globally, which acts through cardiometabolic diseases as precursors to cardiovascular disease, cancer, and other conditions. There is great interest in how the social determinants of health (the conditions in which people are born, live, work, develop, and age) impact cardiometabolic disease. Food insecurity is an example of a powerful social determinant of health that impacts health outcomes. Nutrition insecurity, a distinct but related concept to food insecurity, is a direct determinant of health. In this article, we provide an overview of how diet in early life relates to cardiometabolic disease and then continue to focus on the concepts of food insecurity and nutrition insecurity. In the discussions herein we make important distinctions between the concepts of food insecurity and nutrition insecurity and provide a review of their concepts, histories, measurement and assessment devices, trends and prevalence, and links to health and health disparities. The discussions here set the stage for future research and practice to directly address the negative consequences of food and nutrition insecurity.

A Qualitative Study to Compare Barriers to Improving Food Security among Households with Young Children in the U.S. as Perceived by Different Types of Stakeholders before and during COVID-19

This qualitative study aimed to determine the perceived barriers of different community stakeholders’ to providing resources for improving food security in households with young children in the U.S. Community stakeholders working with low-income families with children 0–3 years of age in Florida were recruited to represent healthcare (n = 7), community/policy development (n = 6), emergency food assistance (n = 6), early childhood education (n = 7), and nutrition education (n = 6) sectors. In 2020, one-on-one interviews were conducted with each stakeholder in via Zoom, using an interview script based on the PRECEDE–PROCEED model and questions to capture the impacts of COVID-19. The interviews were audio-recorded, transcribed verbatim, and analyzed using a deductive thematic approach. A cross-tab qualitative analysis was used to compare data across categories of stakeholders. Healthcare professionals and nutrition educators indicated stigma, community/policy development stakeholders indicated a lack of time, emergency food assistance personnel indicated a limited access to food, and early childhood professionals indicated a lack of transportation as the main barriers to food security prior to COVID-19. COVID-19 impacts included the fear of virus exposure, new restrictions, lack of volunteers, and a lack of interest in virtual programming as barriers to food security. As perceived barriers may vary with respect to providing resources to improve food security in families with young children and the COVID-19 impacts persist, coordinated policy, systems, and environmental changes are needed.

Nutritional changes during the COVID-19 pandemic: a rapid scoping review on the impact of psychological factors

COVID-19 and the resulting measures to curb the spread of the virus have significantly changed our lives, including our nutritional choices. In this rapid scoping review an overview is provided of what psychological factors may be associated with peoples' eating behaviour during COVID-19 restrictions. Relevant literature was identified using PubMed, PsycInfo, CINAHL and MEDLINE databases from 2019 onwards. For included studies, information on study characteristics, eating behaviours, and psychological factors were extracted. 118 articles were included, representing 30 countries. Findings indicated that most people consumed more and unhealthy food in times of COVID-19 restrictions, while some consumed less but often for the wrong reasons. Several psychological factors, related to (1) affective reactions, (2) anxiety, fear and worriers, (3) stress and (4) subjective and mental wellbeing were found to be associated with this increase in food consumption. These outcomes may help to be better inform future interventions, and with that, to be better prepared in case of future lockdown scenarios.

Predictors of Overweight and Obesity in Early Care and Education Teachers during COVID-19

The purpose of this cross-sectional study was to determine individual, sociocultural, policy, and economic predictors of overweight/obesity in early care and education (ECE) teachers to identify modifiable opportunities to enhance the health of this critical workforce. ECE teachers (n = 1434) in the U.S. completed an online survey in late spring to mid-summer 2020. Teachers self-reported height and weight; body mass index (BMI) and weight status were calculated. Teachers reported micro-environment variables including age, race, gender, obesogenic lifestyle behaviors, well-being, food security, personal health, stress, job stress, type of ECE, COVID-19 teaching modality, and age of children in the classroom. Logistic regression predicting overweight/obesity and linear regression predicting BMI were conducted. Teachers with more years of teaching experience (OR: 1.022: 95% CI 1.005, 1.039) and higher consumption of fast food (2.038: 1.310, 3.169) had higher odds of overweight/obesity. Teachers with higher levels of education (0.58: 0.407, 0.828) and higher physical health (0.836: 0.775, 0.902) had lower odds of overweight/obesity. Other variables were not associated with overweight/obesity. Variables significant in logistic regression were also associated with higher BMI. Additionally, Native American race (β = 2.467 SE = 1.206) and sedentary hours/day (β = 0.152 SE = 0.075) were associated with higher BMI. Implications for enhancing workplace health for these ECE teachers are emerging.

The Determinants of Food Insecurity Among Hispanic/Latinx Households With Young Children: A Narrative Review

Food insecurity has disproportionately impacted Hispanic/Latinx households in the United States, specifically those with young children. Although the literature provides evidence of an association between food insecurity and adverse health outcomes in young children, minimal research has addressed the social determinants and related risk factors associated with food insecurity among Hispanic/Latinx households with children under three, a highly vulnerable population. Using the Socio-Ecological Model (SEM) as a framework, this narrative review identified factors associated with food insecurity among Hispanic/Latinx households with children under three. A literature search was conducted using PubMed and four additional search engines. Inclusion criteria consisted of articles published in English from November 1996 to May 2022 that examined food insecurity among Hispanic/Latinx households with children under three. Articles were excluded if conducted in settings other than the US and/or focused on refugees and temporary migrant workers. Data were extracted (i.e., objective, setting, population, study design, measures of food insecurity, results) from the final articles (n = 27). The strength of each article's evidence was also evaluated. Results identified individual factors (i.e., intergenerational poverty, education, acculturation, language, etc.), interpersonal factors (i.e., household composition, social support, cultural customs), organizational factors (i.e., interagency collaboration, organizational rules), community factors (i.e., food environment, stigma, etc.), and public policy/societal factors (i.e., nutrition assistance programs, benefit cliffs, etc.) associated with a food security status of this population. Overall, most articles were classified as "medium" or higher quality for the strength of evidence, and more frequently focused on individual or policy factors. Findings indicate the need for more research to include a focus on public policy/society factors, as well as on multiple levels of the SEM with considerations of how individual and policy levels intersect and to create or adapt nutrition-related and culturally appropriate interventions to improve food security of Hispanic/Latinx households with young children.

A mixed-method systematic review and meta-analysis of the influences of food environments and food insecurity on obesity in high-income countries

Obesity remains a serious public health concern in rich countries and the current obesogenic food environments and food insecurity are predictors of this disease. The impact of these variables on rising obesity trends is, however, mixed and inconsistent, due to measurement issues and cross-sectional study designs. To further the work in this area, this review aimed to summarize quantitative and qualitative data on the relationship between these variables, among adults and children across high-income countries. A mixed-method systematic review was conducted using 13 electronic databases, up to August 2021. Two authors independently extracted data and evaluated quality of publications. Random-effects meta-analysis was used to estimate the odds ratio (OR) for the association between food insecurity and obesity. Where statistical pooling for extracted statistics related to food environments was not possible due to heterogeneity, a narrative synthesis was performed. Meta-analysis of 36,113 adults and children showed statistically significant associations between food insecurity and obesity (OR: 1.503, 95% confidence interval: 1.432-1.577, p < .05). Narrative synthesis showed association between different types of food environments and obesity. Findings from qualitative studies regarding a reliance on energy-dense, nutrient-poor foods owing to their affordability and accessibility aligned with findings from quantitative studies. Results from both qualitative and quantitative studies regarding the potential links between increased body weight and participation in food assistance programs such as food banks were supportive of weight gain. To address obesity among individuals experiencing food insecurity, wide-reaching approaches are required, especially among those surrounded by unhealthy food environments which could potentially influence food choice.

Association of Food Insecurity and Food Addiction Symptoms: A Secondary Analysis of Two Samples of Low-Income Female Adults

BACKGROUND

Household food insecurity persists in the United States and has important implications for health and well-being. Food insecurity in female-identified caregivers is particularly concerning, given its association with their mental health and adverse health outcomes for their children. Food insecurity is associated with disordered eating but, to our knowledge, no prior studies have examined an association between food insecurity and food addiction.

OBJECTIVE

Our aim was to examine whether food insecurity is associated with higher food addiction symptom endorsement in low-income female adults.

DESIGN

Secondary analysis of baseline data from a quasi-experimental study of a mindfulness-based intervention on gestational weight gain among low-income pregnant individuals and an observational study of low-income families.

PARTICIPANTS/SETTING

Participants in study 1 (n = 208) were English-speaking, low-income pregnant individuals with overweight or obesity, recruited in California from 2011 to 2013. Participants in study 2 (n = 181) were English-speaking, low-income female caregivers for children aged 8 through 10 years, recruited in Michigan from 2018 to 2019. Both studies recruited participants from community health clinics, social service agencies, and online advertisements.

MAIN OUTCOME MEASURES

The primary outcome measure was food addiction symptoms, assessed by the Yale Food Addiction Scale.

STATISTICAL ANALYSIS

Multivariate Poisson regression was used to examine the association between household food insecurity and food addiction symptoms in each sample, adjusted for sociodemographic characteristics.

RESULTS

In study 1, pregnant individuals in food-insecure households reported 21% higher food addiction symptoms than pregnant individuals in food-secure households (incidence rate ratio 1.21; 95% CI 1.00 to 1.47; P = .047). In study 2, caregivers in food-insecure households had 56% higher food addiction symptoms than caregivers in food-secure households (incidence rate ratio 1.56; 95% CI 1.01 to 2.40; P = .045).

CONCLUSIONS

These findings provide preliminary support for a relationship between household food insecurity and food addiction. Future research should examine potential mechanisms and whether interventions to reduce food insecurity lower risk of food addiction.

Food insecurity, food environments, and disparities in diet quality and obesity in a nationally representative sample of community-dwelling older Americans

Food insecurity, reflecting a household's low ability to purchase healthy food, is a public health concern that is associated with poor diet and obesity. Poor food environments, characterized as a neighborhood with low access to healthy, affordable food, may amplify the negative impact of food insecurity on diet and obesity. This study aims to investigate whether food insecurity and food environments are jointly associated with an increased risk of poor diet quality and obesity. We used data from a nationally representative sample of community-dwelling older adults in the Health and Retirement Study Health Care and Nutrition Survey and the National Neighborhood Data Archive to investigate the role of household and neighborhood characteristics on diet and obesity. Weighted regression models were estimated to examine the relationship between food insecurity and food environments as well as their interaction with diet quality and obesity. Food insecure respondents had lower Healthy Eating Index scores and were more likely to be obese than food secure respondents. Living in a poor food environment was associated with lower Healthy Eating Index scores, but not with obesity. We did not find any interaction between food insecurity and food environment in determining either healthy eating or obesity. Reducing food insecurity and increasing access to healthy food environments may encourage healthier eating among older adults, while alleviating food-related hardship may also reduce their obesity risk.

Food insecurity as a risk factor for obesity: A review

Obesity is considered a 21^st-century epidemic and it is a metabolic risk factor for Non-Communicable Diseases such as cardiovascular diseases, type 2 diabetes, metabolic syndrome, hypertension, some types of cancer, among others. Thus, its prevention and treatment are important public health concerns. Obesity within the context of food insecurity adds an additional layer of complexity to the current obesity epidemic. Efficient policies and interventions ought to take into consideration the effects of food insecurity on the risks of developing obesity among food insecure households. This review aims to analyze the recent available evidence around the obesity – food insecurity paradox. Most of the literature has consistently shown that there is a significant association between food insecurity and obesity, specifically in women of high-income countries. However, mechanisms explaining the paradox are still lacking. Even though researchers have tried to analyze the issue using different individual and societal variables, these studies have failed to explain the mediatory mechanisms of the food insecurity–obesity relationship since the proposed mechanisms usually lack strength or are purely theoretical. The research focus should shift from cross-sectional models to other research designs that allow the exploration of pathways and mechanisms underlying the food insecurity and obesity relationship, such as longitudinal studies, which will hopefully lead to consecutive research testing the effectiveness of different approaches and scale up such interventions into diverse contexts among those affected by obesity and the different degrees of food insecurity.

Setting Preconception Care Priorities in Australia Using a Delphi Technique

Preconception health affects fertility, pregnancy, and future health outcomes but public awareness of this is low. Our aims were to rank priorities for preconception care (PCC), develop strategies to address these priorities, and establish values to guide future work in preconception healthcare in Australia. A Delphi technique involved two rounds of online voting and mid-round workshops. Inputs were a scoping review of PCC guidelines, a priority setting framework and existing networks that focus on health. During July and August, 2021, 23 multidisciplinary experts in PCC or social care, including a consumer advocate, completed the Delphi technique. Ten priority areas were identified, with health behaviors, medical history, weight, and reproductive health ranked most highly. Six strategies were identified. Underpinning values encompassed engagement with stakeholders, a life course view of preconception health, an integrated multi-sectorial approach and a need for large scale collaboration to implement interventions that deliver impact across health care, social care, policy and population health. Priority populations were considered within the social determinants of health. Health behaviors, medical history, weight, and reproductive health were ranked highly as PCC priorities. Key strategies to address priorities should be implemented with consideration of values that improve the preconception health of all Australians.

Food insecurity and severe mental illness: understanding the hidden problem and how to ask about food access during routine healthcare

Food insecurity occurs when an individual lacks the financial resources to ensure reliable access to sufficient food to meet their dietary, nutritional and social needs. Adults living with mental ill health, particularly severe mental illness, are more likely to experience food insecurity than the general adult population. Despite this, most interventions and policy reforms in recent years have been aimed at children and families, with little regard for other vulnerable groups. Initiating a conversation about access to food can be tricky and assessing for food insecurity does not happen in mental health settings. This article provides an overview of food insecurity and how it relates to mental ill health. With reference to research evidence, the reader will gain an understanding of food insecurity, how it can be assessed and how food-insecure individuals with severe mental illness can be supported. Finally, we make policy recommendations to truly address this driver of health inequality.

Chronic experience with unpredictable food availability promotes food reward, overeating, and weight gain in a novel animal model of food insecurity

Ubiquitous, easy access to food is thought to promote obesity in the modern environment. However, people coping with food insecurity have limited, unpredictable food access and are also prone to obesity. Causal factors linking food insecurity and obesity are not understood. In this study we describe an animal model to investigate biopsychological impacts of the chronic unpredictability inherent in food insecurity. Female rats were maintained on a 'secure' schedule of highly predictable 4x/day feedings of uniform size, or an 'insecure' schedule delivering the same total food over time but frequently unpredictable regarding how much, if any, food would arrive at each scheduled feeding. Subgroups of secure and insecure rats were fed ordinary chow or high-fat/high-sugar (HFHS) chow to identify separate and combined effects of insecurity and diet quality. Insecure chow-fed rats, relative to secure chow-fed rats, were hyperactive and consumed more when provided a palatable liquid diet. Insecure HFHS-fed rats additionally had higher progressive ratio breakpoints for sucrose, increased meal size, and subsequently gained more weight during 8 days of ad libitum HFHS access. Insecurity appeared to maintain a heightened attraction to palatable food that habituated in rats with secure HFHS access. In a second experiment, rats fed ordinary chow on the insecure schedule subsequently gained more weight when provided ad libitum chow, showing that prior insecurity per se promoted short-term weight gain in the absence of HFHS food. We propose this to be a potentially useful animal model for mechanistic research on biopsychological impacts of insecurity, demonstrating that chronic food uncertainty is a factor promoting obesity.

A Qualitative Study Exploring Management of Food Intake in the United Kingdom During the Coronavirus Pandemic

The coronavirus pandemic has impacted dietary quality through increased emotional eating and extended time spent at home, as well as instances of panic buying due to uncertainty over food availability. We recruited an opportunistic sample of 40 adults living in the United Kingdom (Female = 25; Mean age = 41.9 years) (SD = 14.4) without any prior history of eating disorders. Semi-structured interviews were conducted in June 2020 and focused on the impacts of the COVID-19 lockdown on eating habits and experiences of panic buying. The data were transcribed and organized using the softwares Otter and Quirkos, respectively. Reflexive thematic analysis identified positive and negative changes to eating habits. Overall, themes highlighted that effective organization was vital to manage food purchases and consumption due to a reduced shopping frequency. However, overconsumption frequently occurred due to boredom and ease of accessing energy dense foods, which had negative implications for weight and body image. After indulging, participants attempted to revert to prior eating habits and adhere to a nutritious diet. Many also expressed the importance of having enough food to feed families, which was often reported as a reason for buying extra supplies. Understanding the long-term impacts of changes to eating habits that account for the novel coronavirus context is required to preserve health and prevent unintended changes to weight.

The effect of acute and chronic scarcity on acute stress: A dyadic developmental examination

BACKGROUND

Food insecurity, obesity, and psychological stress are interrelated constructs which are thought to be connected through increased energy intake, but the underlying mechanisms for these relationships remain unclear. The current study used experimental methods to investigate how financial losses may influence acute stress in the context of food insecurity for both parents and offspring. This study also sought to examine the effect of acute stress related to financial losses on the reinforcing value of food (RRV_food) and delay discounting (DD).

METHODS

One hundred and six families stratified by both offspring age (53 children aged 7-10, 53 adolescents aged 15-17) and household financial resources, visited our laboratory for three separate appointments. Each appointment included the experimental manipulation of financial gains and losses, saliva samples for cortisol assay, continuous heart rate monitoring, self-rated tension, and computer-based DD and RRV_food tasks. Participants also completed surveys to report perceived life stress level and food insecurity status.

RESULTS

Among all participants, financial losses were related to decreased heart rates and increased self-rated tension. Among parents reporting food insecurity, acute financial losses resulted in an increase in cortisol levels. Changes in cortisol, heart rate, and tension were not related to RRV_food or DD.

CONCLUSION

Food insecure parents are sensitive to financial losses and respond with an increase in cortisol. However, we found no evidence for a relationship between cortisol and RRV_food or DD. This sensitivity to financial losses did not extend to children or adolescents.

The association between COVID-19 related food insecurity and weight promoting eating behaviours: The mediating role of distress and eating to cope

Food insecurity (a lack of stable access to nutritious food) is reliably associated with higher BMI, although the underlying mechanisms are unclear. Past research indicates that this relationship may, in part, be explained by the distress of being food insecure and using food as a coping mechanism. While previous work has focused on long-term food insecurity, the first COVID-19 national lockdown presented a unique opportunity to establish if the same relationships existed for individuals experiencing pandemic related food insecurity. Adults in the United Kingdom (N = 211) were recruited three months after the first UK lockdown via social media. They completed questionnaires on COVID-19 related food insecurity, physical stress, psychological distress, eating to cope, drinking to cope, diet quality, and changes in weight promoting eating behaviours (e.g. consuming larger portions, increased snacking) since the start of the lockdown. A structural equation model revealed that food insecurity was indirectly associated with changes in weight promoting eating behaviours. As predicted, the more instances of pandemic related food insecurity, the more distress individuals reported. Distress was then associated with eating as a way of coping, which in turn was associated with increases in weight promoting eating behaviours. Food insecurity was also indirectly associated with diet quality, but this was via distress only. These results reflect similar pathways observed in individuals reporting chronic food insecurity and strengthens the evidence that distress and eating to cope are generic mediators of food insecurity and eating behaviour.

Food Insecurity and Cardiometabolic Conditions: a Review of Recent Research

PURPOSE OF REVIEW

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

RECENT FINDINGS

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

Yeast volatiles double starvation survival in Drosophila

Organisms make decisions based on the information they gather from their environment, the effects of which affect their fitness. Understanding how these interactions affect physiology may generate interventions that improve the length and quality of life. Here, we provide evidence that exposure to live yeast volatiles during starvation significantly extends survival, increases activity, and slows the rate of triacylglyceride (TAG) decline independent of canonical sensory perception. We demonstrate that ethanol (EtOH) is one of the active components in yeast volatiles that influences these phenotypes and that EtOH metabolites mediate dynamic mechanisms to promote Drosophila survival. Silencing R4d neurons reverses the ability of high EtOH concentrations to promote starvation survival, and their activation promotes EtOH metabolism. The transcription factor foxo promotes EtOH resistance, likely by protection from EtOH toxicity. Our results suggest that food-related cues recruit neural circuits and modulate stress signaling pathways to promote survival during starvation.
