Food insecurity and mental health: a systematic review and meta-analysis

Food insecurity and symptoms of anxiety and depression disorder during the COVID- 19 pandemic: COVID-Inconfidentes, a population-based survey

This study aimed to investigate the association between adult food insecurity (FI) and symptoms of generalized anxiety disorder (GAD) and major depressive disorder (MDD) in two Brazilian cities during the coronavirus disease (COVID-19) pandemic. This study used data derived from a cross-sectional survey of 1693 adults. Interviews were conducted using an electronic questionnaire. The FI was measured using the Brazilian Food Insecurity Scale. The Generalized Anxiety Disorder-7 was used to measure the symptoms of GAD. The Patient Health Questionnaire-9 was used for MDD symptoms. The association between FI, GAD, and MDD symptoms was investigated using a Poisson regression model with robust variance to estimate the prevalence ratio and 95% confidence interval (95% CI). In regression models, a linear association between FI levels and outcomes was observed, with severe food insecurity having a 3.56 higher prevalence of GAD symptoms (95% CI: 2.23, 5.68) and a 3.03 higher prevalence of MDD (95% CI: 1.55, 5.90). In the stratified analyses, worse results were observed for females and males, individuals with non-white race/skin color, those without children, and those with lower monthly family income. In conclusion, the FI was associated with symptoms of GAD and MDD, and the sociodemographic characteristics interfered in this association. Therefore, we recommend the improvement of public health and social protection policies for food-insecure people.

How gender, education and nutrition knowledge contribute to food insecurity among adults in Australia

Food and nutrition insecurity occurs when healthy and safe food cannot be obtained by socially acceptable means and arises as a result of complex interactions between socioeconomic and demographic determinants. These factors contribute to discrepancies in health and well-being between men and women and may also explain differential rates of food insecurity. The objectives of this cross-sectional study were to investigate the intersection between gender, education, nutrition knowledge and food security status within a high-income country context. Australian adults over 16 years of age who identified as having primary responsibility for food in their household were recruited via social media and a panel. Respondents completed a self-administered survey that included sociodemographic data, nutrition-related knowledge and food security status. Food security was measured using the Australian Household Food and Nutrition Security Scale an adapted version of the United States Department of Agriculture Household Food Security Survey. Among the 1010 survey respondents, household food insecurity (HFI) was highly prevalent (43% were food insecure, with 26% of these severely food insecure). Gender may affect associations between education, nutrition knowledge and HFI. Education was significantly associated with HFI among women but not among men. Conversely, nutrition knowledge was significantly inversely associated with food security among men but not among women. Differences in determinants of HFI exist between men and women, and programs aimed at addressing food insecurity may be more effective if tailored accordingly to account for the social and demographic factors associated with HFI.

Food Insecurity among Low-Income Households with Children Participating in a School-Based Fruit and Vegetable Co-Op

The purpose of this study was to evaluate the impact of a nutrition intervention on food insecurity among low-income households with children. Data were collected from 371 parent−child dyads in a quasi-experimental evaluation study of a 1-year intervention (n = 6 intervention schools receiving Brighter Bites, n = 6 wait-list control schools), and longitudinal follow-up of the intervention group 2 years post-intervention in Houston, Texas. Data were collected at three timepoints: at baseline and 1 year for all participants, and at 2 year follow-up for the intervention group (the wait-list control group received the intervention during that time). At baseline, most parents reported food insecurity (60.6%; 70% intervention group, 53.6% control). Food insecurity decreased significantly from 81.3% to 61.7% [(−0.32, −0.07) p = 0.002] among intervention participants immediately post-intervention. After adjusting for ethnicity, 2 years post-intervention the predicted percentage of participants reporting food insecurity decreased significantly by roughly 35.4% from 76.4% at baseline to 41.0% [(−0.49, −0.22), p < 0.001]. Between-group changes were not significant. The re-sults of this study demonstrated a significant positive impact of Brighter Bites on food security in the short and long-term among low-income households with children, albeit results should be in-terpreted with caution.

The effect of food insecurity and stress on delay discounting across families: a COVID-19 natural experiment

BACKGROUND

Delay Discounting is the extent to which one prioritizes smaller immediate rewards over larger, delayed rewards. The ability to prospect into the future is associated with better health decision-making, which suggests that delay discounting is an important intervention target for the prevention and treatment of chronic disease. Delay discounting decreases throughout development and stressful experiences, particularly those that accompany poverty, may influence this developmental trajectory. The current study leveraged the COVID-19 pandemic and resulting economic downturn as a natural experiment to understand how changes in food insecurity and psychological stress may associated with changes in delay discounting among parents, adolescents, and children.

METHODS

A stratified cohort of families (N = 76 dyads), established prior to the initial pandemic lockdowns, were asked to complete a follow-up survey in the summer of 2020, during reopening. Thirty-seven (49%) families had an older adolescent (aged 15 - 18 years) in the study and 39 (51%) had an elementary aged child (aged 7 - 12 years) in the follow-up study. Both data collection points included measurements of economic position, psychological stress, food security status, and delay discounting.

RESULTS

The results showed that pandemic food insecurity was associated with greater stress among parents (β = 2.22, t(65.48) = 2.81, p = 0.007). Parents, Adolescents, and children significantly differed in their response to psychological stress during the pandemic (β = -0.03, t(102.45) = -2.58, p = 0.011), which was driven by a trend for children to show greater delay discounting associated with an increase in psychological stress during the pandemic (β = -0.01, p = 0.071), while adolescents and parents showed no change.

CONCLUSIONS

These findings add to the evidence that food insecurity is uniquely stressful among parents with no effects on delay discounting. Despite this, we found no evidence that food insecurity was stressful for child or adolescents. A trend in our data suggested that childhood, as compared with adolescence, may be an important developmental period for the association between stress and delay discounting. Future research should continue the longitudinal investigation of childhood stress and the developmental trajectory of delay discounting to ascertain how these effects may persist in adulthood.

Burden of Food Insecurity and Mental Health Symptoms among Adults with Cardiometabolic Conditions during the COVID-19 Pandemic

Our study objectives were to (1) identify the national prevalence and patterns of food insecurity among adults with and without a history of CMCs and (2) determine associations between food insecurity and mental health outcomes among adults with CMCs during the early COVID-19 pandemic period (April−June 2020). We computed prevalence ratios with Poisson regression using the robust estimation of standard errors to identify disparities in the report of food insecurity across demographic groups and by CMC history. Among adults with CMCs, we estimated associations between food insecurity and self-reported mental health symptoms using multinomial logistic regression. Overall, people with CMCs were more likely to be older, White, without employment in the past 7 days, and from the South or an urban environment. We found that the determinants of food insecurity among individuals with cardiometabolic conditions include having: <60 years of age, female sex, Black or Hispanic race/ethnicity, an educational degree lower than a baccalaureate, a household income of <$100,000, and either Medicaid, Indian Health Insurance, or no insurance. Individuals with CMCs and food insecurity also had significantly higher odds of adverse mental health symptoms. The continued clinical screening of food insecurity and mental health, as well as public health interventions, targeted toward individuals with CMCs, should be prioritized as we move through the COVID-19 pandemic.

Systematic evidence and gap map of research linking food security and nutrition to mental health

Connections between food security and nutrition (FSN) and mental health have been analytically investigated, but conclusions are difficult to draw given the breadth of literature. Furthermore, there is little guidance for continued research. We searched three databases for analytical studies linking FSN to mental health. Out of 30,896 records, we characterized and mapped 1945 studies onto an interactive Evidence and Gap Map (EGM). In these studies, anthropometry (especially BMI) and diets were most linked to mental health (predominantly depression). There were fewer studies on infant and young child feeding, birth outcomes, and nutrient biomarkers related to anxiety, stress, and mental well-being. Two-thirds of studies hypothesized FSN measures as the exposure influencing mental health outcomes. Most studies were observational, followed by systematic reviews as the next largest category of study. One-third of studies were carried out in low- and middle-income countries. This map visualizes the extent and nature of analytical studies relating FSN to mental health and may be useful in guiding future research.

There is a broad range of research available on the relationship between food security and mental health. Here the authors carry out a systematic mapping of evidence on food security and nutrition related to mental health and identifies trends in themes, setting, and study design over the 20 year period studied.

The Impact of Climate Change on Mental Health and Emotional Wellbeing: A Narrative Review of Current Evidence, and its Implications

Converging global evidence highlights the dire consequences of climate change for human mental health and wellbeing. This paper summarises literature across relevant disciplines to provide a comprehensive narrative review of the multiple pathways through which climate change interacts with mental health and wellbeing. Climate change acts as a risk amplifier by disrupting the conditions known to support good mental health, including socioeconomic, cultural and environmental conditions, and living and working conditions. The disruptive influence of rising global temperatures and extreme weather events, such as experiencing a heatwave or water insecurity, compounds existing stressors experienced by individuals and communities. This has deleterious effects on people's mental health and is particularly acute for those groups already disadvantaged within and across countries. Awareness and experiences of escalating climate threats and climate inaction can generate understandable psychological distress; though strong emotional responses can also motivate climate action. We highlight opportunities to support individuals and communities to cope with and act on climate change. Consideration of the multiple and interconnected pathways of climate impacts and their influence on mental health determinants must inform evidence-based interventions. Appropriate action that centres climate justice can reduce the current and future mental health burden, while simultaneously improving the conditions that nurture wellbeing and equality. The presented evidence adds further weight to the need for decisive climate action by decision makers across all scales.

Food Insecurity and Mental Well-Being in Immigrants: A Global Analysis

INTRODUCTION

This study estimates the prevalence of food insecurity, mental well-being, and their associations among immigrants and compares the food insecurity-mental well-being associations with nonimmigrants globally and by region.

METHODS

The Gallup World Poll data from 2014 to 2019 were analyzed in 2021. A total of 36,313 immigrants and 705,913 nonimmigrants were included. Food insecurity was measured by the Food Insecurity Experience Scale. Mental well-being was assessed using the Negative Experience Index and Positive Experience Index. A community attachment index was used to measure the living environment. Multilevel mixed-effect linear models were used to examine how the Negative Experience Index/Positive Experience Index was associated with food insecurity and the community attachment index in immigrants and nonimmigrants, adjusting for sociodemographic characteristics, survey years, and country fixed effects. The modifying effects of immigration status on food insecurity-mental well-being associations were tested.

RESULTS

The weighted proportion of food insecurity among global immigrants was 38.6% during 2014-2019. In the pooled adjusted model, food insecurity was dose-responsively associated with greater Negative Experience Index and lower Positive Experience Index than the food-secure ref (p<0.001 for trend). Similar dose-response associations were observed in nonimmigrants and in region-specific analyses. Community attachment marginally affected the food insecurity-mental well-being associations (all p≤0.001 for interaction). Immigration status significantly modified the food insecurity-mental well-being associations in all analyses (all p=0.01 for interaction), and immigrants experienced poorer mental well-being than nonimmigrants at the same level of community attachment and food insecurity.

CONCLUSIONS

Food insecurity is prevalent and is associated with poor mental well-being in immigrants worldwide. Future interventions are needed to alleviate food insecurity and promote community attachment to improve mental health among immigrants, especially in Asian and Pacific countries.

Mental Health Disturbance after a Major Earthquake in Northern Peru: A Preliminary, Cross-Sectional Study

Little has been studied in Peru on the mental health repercussions after a major earthquake. We aimed to explore the factors associated with depressive and anxiety symptoms in people who experienced a 6.1 magnitude earthquake in Piura, Peru, on 30 July 2021. A preliminary cross-sectional study was conducted in the general population between August–September 2021. An online questionnaire was provided using PHQ-9, GAD-7, and other relevant measures. Generalized linear models were applied. Of the 177 participants, the median age was 22 years, the majority were female (56%), and many experienced depressive (52%) or anxiety symptoms (52%). Presence of depressive symptoms was associated with a personal history of mental disorder, moderate housing damage, social/material support from politicians, moderate food insecurity, and insomnia. Presence of anxiety symptoms was associated with physical injury caused by the earthquake, mild food insecurity, and insomnia. The development of depressive and anxiety symptoms following the 2021 earthquake experienced in Piura depended on multiple individual and socioeconomic factors. Additional studies should reinforce the factors identified here given the methodological limitations, such as the study design, sampling method, and sample size. This would lead to effective intervention measures to mitigate the impact of earthquakes on mental health.

Economic strain, parental education and psychotic experiences among college students in the United States: Findings from the Healthy Minds Study 2020

AIM

Socioeconomic status (SES) is linked to psychosis, and much can be learned by examining how various indicators of SES-specifically economic strain and intergenerational transfer of resources-are related to sub-threshold psychotic experiences among college students.

METHODS

Using data from the Healthy Minds Survey (September 2020-December 2020), we used multivariable logistic regression models to examine the associations between five SES indicators and 12-month psychotic experiences, adjusting for age, gender and race/ethnicity. We also examined the count of predictors and psychotic experiences.

RESULTS

Each indicator of economic strain was associated with greater odds of psychotic experiences. In particular, increasing levels of financial stress (current, childhood and pandemic-related) were associated with greater odds of psychotic experiences in a dose-response fashion. Food insecurity was associated with double the odds of psychotic experiences. In terms of intergenerational transfer of resources, having either one or no parents who attended college was associated with significantly greater odds of having psychotic experiences, when compared with having both parents who attended college. Examining all predictors in the same model, only childhood and current financial stress and food insecurity were significantly associated with psychotic experiences. The count of predictors was significantly associated with greater odds of having psychotic experiences in a dose-dependent fashion.

CONCLUSIONS

Among college students, economic strain and intergenerational transfer of resources were associated with recent psychotic experiences, highlighting the importance of economic interventions targeting young adults to influence risk for psychosis.

High occurrence of food insecurity in young people attending a youth mental health service in regional Australia

Aim

Despite the relationship between food insecurity and poor mental health, food insecurity in young people attending mental health services in Australia remains understudied. This study aimed to determine the occurrence and predictors of food insecurity, and the relationship with dietary factors in young people attending a mental health service.

Methods

A cross‐sectional online survey was conducted in a sample of young people (15–25 years) who attended a mental health service in Launceston, Australia. The survey utilised a single‐item food insecurity screening tool and eight demographic, health and service use questions. Five questions determined self‐reported intake of fruit, vegetables, breakfast, water, sugar‐sweetened beverages and takeaway foods. Binary logistic regression determined predictors of food insecurity. Cross‐tabulations determined differences in dietary intake according to food security.

Results

Of survey respondents (n = 48; 68% female), 40% (n = 19) were food insecure. Respondents living out of home or in unstable accommodation were at significantly higher risk of food insecurity (odds ratio [OR]: 4.43; SE: 0.696; 95% CI: 1.13–17.34; p = 0.032) compared to those living with their parents. Those receiving government financial assistance (OR: 5.00; SE: 0.676; 95% CI: 1.33–18.81; p = 0.017) were also at significantly higher risk of food insecurity. Regardless of food security status, self‐reported intake of fruits, vegetables and breakfast were low, and respondents regularly consumed takeaway foods and sugar‐sweetened beverages.

Conclusions

There was a high occurrence of food insecurity and poor dietary intake in young people attending a youth mental health service demonstrating that initiatives to support access to healthy food in this group should be a priority, with potential benefits for mental health outcomes.

Lifestyle behaviors in Swedish university students before and during the first six months of the COVID-19 pandemic: a cohort study

Background

Changes in Swedish university students’ lifestyle behaviors during the COVID-19 pandemic are unknown. This study aimed to assess physical activity, sitting time, meal frequency and risk substance use (alcohol, tobacco, and illicit use of drugs) in Swedish university students before and during the first six months of the COVID-19 pandemic, for all and stratified by age and sex.

Methods

Data were obtained from the Sustainable University Life cohort study in which web-based surveys were sent to university students repeatedly for one year. Baseline assessment (before the pandemic) was between August 2019-March 2020, follow-up 1 (FU1) between March-June 2020, and follow-up 2 (FU2) between June–September 2020. Participants reported weekly minutes of physical activity, daily sitting hours, meal frequency by weekly intake of different meals, and motivation for eating irregularly, if so. Also, harmful use of alcohol, tobacco and illicit drugs was assessed. Population means and differences with 95% confidence intervals (95% CI) in lifestyle behaviors between time points were calculated with Generalized Estimating Equations.

Results

1877 students (73% women, mean age 26.5 years) answered the baseline survey. Weekly exercise decreased by -5.7 min (95% CI: -10.0, -1.5) and -7.7 min (95% CI: -12.6, -2.8) between baseline and FU1 and FU2, respectively. Weekly daily activities increased by 5.6 min (95% CI: 0.3, 11.7) and 14.2 min (95% CI: 7.9, 20.5) between baseline and FU1 and FU2. Daily sitting time decreased by -1.4 h (95% CI: -1.7, -1.2) between baseline and FU2. Breakfast intake increased by 0.2 days per week (95% CI: 0.1, 0.3) between baseline and FU2. Lunch intake decreased by -0.2 days per week (95% CI: -0.2, -0.1) between baseline and FU1 and by -0.2 days per week (95% CI: -0.3, -0.0) between baseline and FU2. Dinner intake decreased by -0.1 days per week (95% CI: -0.2, -0.0) between baseline and both FU1 and FU2. Only minor differences in risk substance use were observed. Similar changes were observed in analyses stratified by age and sex.

Conclusions

Lifestyle behaviors in Swedish university students slightly improved during the first six months of the COVID-19 pandemic compared to before.

Social Relationships, Food Security, Protein Intake, and Hospitalization in Homebound Older Adults: A PATH Analysis

The objective of this study was to measure direct and indirect relationships between food insecurity (FI), protein intake, social relationships, depressive symptoms, and their impact on hospitalization among home-delivered meal (HDM) recipients, compared to controls, using structural equation modeling. The analysis used data from the National Outcomes Evaluation Study (2015-2017) of the OAANSP. HDM recipients' mean usual protein intake was significantly higher than controls, but both groups had mean intakes below recommendations. Eating alone was inversely associated with lower protein intake and greater hospitalizations in controls. FI, prevalent in 25.1% of HDM recipient and 16% of controls, was associated with lower protein intake in both groups. Receiving instrumental social support was directly associated with lesser severity of FI in recipients. and more depressive symptoms only in controls. HDM recipients and controls may be at high risk for protein insufficiency, underscored by high prevalence of FI.

Campus Food Pantry Use Is Linked to Better Health Among Public University Students

OBJECTIVE

To examine retrospectively whether access to a campus food pantry (CFP) is related to improvements in sleep, mental health, and physical health among college students in a public university system.

DESIGN

Retrospective, cross-sectional study of student CFP users who completed an online survey in the summer of 2019.

SETTING

Ten-campus University of California system.

PARTICIPANTS

A total of 1,855 students completed the survey.

MAIN VARIABLES MEASURED

Students reported the number of CFP visits in a usual week or month. Students retrospectively rated their perceived health, depressive symptoms, and sleep sufficiency before and after having food pantry access. The difference between pre- and post-food pantry access responses was calculated.

ANALYSIS

Path analysis was used to examine direct and indirect paths of the relationship between CFP visits with self-reported changes in depressive symptoms and perceived health through positive changes in self-reported sleep sufficiency, controlling for sociodemographic factors.

RESULTS

More monthly CFP visits were directly related to decreased depressive symptoms and improved perceived health (β_depressive = 0.10, P < 0.001; β_health = 0.12, P < 0.001). In addition, more CFP visits were related to improved sleep sufficiency (β = 0.09, P = 0.001), which in turn was related to a decrease in depressive symptoms (β = 0.24, P = 0.001; indirect effect: 0.02, P < 0.01) and improved perceived health (β = 0.23, P < 0.001; indirect effect: 0.02, P < 0.01).

CONCLUSIONS AND IMPLICATIONS

Findings suggest that college campus emergency food access is associated with self-reported improvements in student health outcomes associated with food security. Until more long-term solutions that improve college student nutrition are developed, food pantries may be filling a gap.

Resting-State Functional Connectivity Differences in College Students with and without Food Insecurity

We used functional magnetic resonance imaging (fMRI) to investigate cross-sectional differences in functional connectivity across cognitive networks at rest among age and sex matched college students with very low food security [food insecurity (FI); n = 20] and with high food security (n = 20). The participants completed the Behavior Rating Inventory of Executive Function-2 (BRIEF-2) and Adverse Childhood Experiences (ACEs) questionnaires. Seven-minute resting-state fMRI scans were collected. Independent Component Analysis assessed group connectivity differences in three large-scale networks: the default-mode network (DMN), the frontoparietal network (FPN), and the salience network (SN). FI was associated with poorer Global BRIEF scores (adjusted β = 8.36; 95% CI: 2.32, 14.40) and five BRIEF subscales: Inhibit, Initiate, Working Memory, Plan, and Organize (p-values < 0.05). The students with FI had greater functional connectivity between the FPN and left middle temporal gyrus (cluster size p-FWE = 0.029), the SN and precuneus (cluster size p-FWE < 0.001), and the SN and right middle frontal gyrus (cluster size p-FWE = 0.016) compared to the students with high food security. Exploratory correlations revealed that greater connectivity between the SN and right middle frontal gyrus was associated with poorer BRIEF Inhibit scores (p = 0.038), and greater connectivity between the FPN and left middle temporal gyrus was associated with poorer BRIEF Organize scores (p = 0.024) for the students with FI. Greater functional connectivity between the FPN, DMN, and SN at rest may contribute to executive function difficulties for college students with FI.

Food insecurity and SNAP use among sexual minority people: analysis of a population-based sample from National Health Interview Survey, 2017

Background

Food insecurity is a pressing public health problem. Lesbian, gay, and bisexual (LGB) people are at increased risk for food insecurity, yet this issue remains grossly understudied among this population. The purpose of this study was to add to the existing literature surrounding food insecurity and the use of federal food assistance programs (SNAP) among LGB people.

Methods

This study used publicly available, de-identified data from the 2017 National Health Interview Survey (NHIS). Primary variables were sexual orientation, food security status, and receipt of SNAP. Food security was assessed using the 10-item USDA Family Food Security measure.

Results

In our sample, people who identified as bisexual had the highest rates of food insecurity (23.8%, n = 76). Female sexual minorities were 52% more likely to experience food insecurity (aOR = 1.518, 95% CI 1.105–2.087, p = .01) and 44% more likely to report household SNAP assistance than their heterosexual counterparts (aOR = 1.441, 95% CI 1.025–2.028, p = .03). SNAP partially mediated the association between sexual orientation and food insecurity for LGB females.

Conclusions

Our findings add to the growing empirical evidence documenting food insecurities among sexual minority adults. Our results reiterate the need for sexual orientation to be included in nationally representative federal food security measures.

Examining the Association of Food Insecurity and Being Up-to-Date for Breast and Colorectal Cancer Screenings

BACKGROUND

Food insecurity (FI) has been associated with poor access to health care. It is unclear whether this association is beyond that predicted by income, education, and health insurance. FI may serve as a target for intervention given the many programs designed to ameliorate FI. We examined the association of FI with being up-to-date to colorectal cancer and breast cancer screening guidelines.

METHODS

Nine NCI-designated cancer centers surveyed adults in their catchment areas using demographic items and a two-item FI questionnaire. For the colorectal cancer screening sample (n = 4,816), adults ages 50-75 years who reported having a stool test in the past year or a colonoscopy in the past 10 years were considered up-to-date. For the breast cancer screening sample (n = 2,449), female participants ages 50-74 years who reported having a mammogram in the past 2 years were up-to-date. We used logistic regression to examine the association between colorectal cancer or breast cancer screening status and FI, adjusting for race/ethnicity, income, education, health insurance, and other sociodemographic covariates.

RESULTS

The prevalence of FI was 18.2% and 21.6% among colorectal cancer and breast cancer screening participants, respectively. For screenings, 25.6% of colorectal cancer and 34.1% of breast cancer participants were not up-to-date. In two separate adjusted models, FI was significantly associated with lower odds of being up-to-date with colorectal cancer screening [OR, 0.7; 95% confidence interval (CI), 0.5-0.99)] and breast cancer screening (OR, 0.6; 95% CI, 0.4-0.96).

CONCLUSIONS

FI was inversely associated with being up-to-date for colorectal cancer and breast cancer screening.

IMPACT

Future studies should combine FI and cancer screening interventions to improve screening rates.

Food insecurity, depressive symptoms, and the salience of gendered family roles during the COVID-19 pandemic in South Africa

Extensive research has indicated food insecurity to be associated with depressive symptoms, both of which have been indicated to increase globally during the COVID-19 pandemic. Few studies, however, have made use of nationally representative and longitudinal data to investigate this relationship, making causal claims difficult. In South Africa (SA), as with other low- and middle-income contexts, population-based studies have generally focused on mothers during the perinatal period and other vulnerable groups. This study made use of Cross-Lagged Dynamic Panel Models to examine the relationship between household food insecurity and the depressive symptoms of adults across three waves of the National Income Dynamics Survey–Coronavirus Rapid Mobile Survey (NIDS-CRAM) study collected in 2020 and 2021, a dataset nationally representative of all adults in SA in 2017. Stratification of the sample by gender, parenthood and marital statuses allowed for the assessment of gender differences in family roles that might account for differential impacts of food insecurity on mental health outcomes. The findings of this study indicated a significant impact of food insecurity on the depressive symptoms of adults. Controlling for stable trait-like individual differences eliminated much of this relationship, indicating partial or full mediation by unobserved factors. Gender differences in food security's association with depressive symptoms amongst cohabitating parents following the inclusion of individual effects provided support for a gendered role response. These findings provide further evidence of the complex interactions between sex, gender and health.

Food insecurity and mental health among young adult college students in the United States

BACKGROUND

Food insecurity is prevalent among college students in the United States and has been associated with mental health problems. However, the literature is not entirely consistent and is missing key aspects of mental health.

METHODS

Using cross-sectional data from the Health Minds Study (N = 96,379; September 2020-June 2021), we used multivariable logistic regression to examine associations between food insecurity and several aspects of mental health (i.e., depression, anxiety, languishing, perceived need, loneliness, self-injurious behaviors), adjusting for age, gender, race/ethnicity, financial distress, and parental education.

RESULTS

Food insecurity was associated with greater odds of having depression, anxiety, languishing, perceived need for help, loneliness, and self-injurious behaviors, adjusting for sociodemographic characteristics and markers of socioeconomic status.

CONCLUSION

This study found evidence to suggest that food insecurity is related to poor mental health in a large sample of young adult college students in the United States, calling for targeted interventions.

Daily Food Insecurity Predicts Lower Positive and Higher Negative Affect: An Ecological Momentary Assessment Study

Food insecurity (FI) is a dynamic phenomenon, and its association with daily affect is unknown. We explored the association between daily FI and affect among low-income adults during a 2-seasonal-month period that covered days both pre- and during the COVID-19 pandemic. A total of 29 healthy low-income adults were recruited during fall in 2019 or 2020, 25 of whom were followed in winter in 2020 or 2021. Daily FI (measured once daily) and affect (measured 5 times daily) were collected over the 2nd−4th week in each month. Time-Varying-Effect-Models were used to estimate the association between daily FI and positive/negative affect (PA/NA). Overall, 902 person-days of daily-level data were collected. Daily FI was associated with lower PA in the 3rd and 4th week of fall and winter and with higher NA in the second half of winter months. Similar patterns of FI-affect relations were found pre- and during COVID-19 in the second half of a given month, while unique patterns of positive affect scores in the 2nd week and negative scores in the 1st week were only observed during COVID days. Our study supports a time-varying association between FI and affect in low-income adults. Future large studies are needed to verify the findings; ultimately, better understanding such associations may help identify, target, and intervene in food insecure adults to prevent adverse mental health outcomes.

Food Insecurity and Mental Well-Being Among Low-Income Families During COVID-19 Pandemic

Purpose

To examine the interaction effects of adult and child food insecurity on parents’ and children’s mental well-being.

Design

An online survey study was conducted.

Setting

Two Head Start organizations and the Qualtrics Panel.

Subjects

Four hundred and eight parents under poverty level and having a child aged 3–5 years participated.

Measures

Food insecurity was assessed by the U.S. Household Food Security Survey Module. Parents’ stress, anxiety and depression; and children’s sadness, fear, anger, and positive affect were measured using instruments from HealthMeasures.

Analysis

Multivariate general linear models were performed in SPSS.

Results

Mean age was 31 years, 17% Hispanic, 21% Black. About 51% parents and 37% children were food insecure. After adjusting for demographics and child food insecurity, parents with adult food insecurity had higher stress (B = 2.65, p = .002), anxiety (B = 3.02, p = .001), and depression (B = 3.66, p = .001); and fear in their children (B = 5.03, p = .002) than those without adult food insecurity. Similarly, parents reporting child food insecurity had greater depression than those having no child food insecurity (B = 4.61, p = .020). Black parents had lower stress (B = −1.91, p = .018), anxiety (B = −2.26, p = .012), and depression (B = −4.17, p < .001) than their White counterparts.

Conclusions

The study’s results underscore the importance of reducing food insecurity in both parents and children as a whole family system to promote mental well-being of low-income families.

Food insecurity among Finnish private service sector workers: validity, prevalence and determinants

OBJECTIVE

To examine the prevalence and determinants of food insecurity among private sector service workers in Finland and assess validity of the Household Food Insecurity Access Scale (HFIAS) tool.

DESIGN

In this cross-sectional study, food insecurity and background characteristics were collected from Finnish private service workers via electronic questionnaires (2019) and national register data (2018-2019). We conducted univariate and multivariate logistic regression analyses to determine the variables explaining food insecurity. Validity of HFIAS was assessed with rotated principal component analysis and Cronbach's α.

SETTING

Members of the trade union for private sector service workers, Service Union United (PAM), from all municipalities in Finland participated in the study in 2019.

PARTICIPANTS

The subjects were 6435 private sector workers that were members of the Service Union United (PAM) in Finland. Mean age of participants was 44 years (sd 12·7 years).

RESULTS

Two-thirds of the participants (65 %) were food insecure with over a third (36 %) reporting severe food insecurity. Reporting great difficulties in covering household expenses and young age markedly increased the risk of severe food insecurity (OR 15·05; 95 % CI 10·60, 21·38 and OR 5·07; 95 % CI 3·94, 6·52, respectively). Not being married, low education, working in the hospitality industry, being male and living in rented housing also increased the probability of severe food insecurity. The HFIAS tool demonstrated acceptable construct and criterion validity.

CONCLUSIONS

Severe food insecurity was widespread and associated with low socio-economic status, young age and being male among Finnish private sector service workers, emphasising the need for regular monitoring of food insecurity in Finland.

Food Insecurity across the Life-Course and Cognitive Function among Older Mexican Adults

BACKGROUND

Food insecurity remains a global public health problem. Experiencing food insecurity is related to poorer cognitive function among older adults. However, few studies have examined how food insecurity, experienced over the life-course, relates to cognitive function among older adults in Mexico.

METHODS

Data came from the 2015 Mexican Health and Aging Study (n = 11,507 adults aged 50 and over). Early- and late-life food insecurity were ascertained by self-report. We evaluated how both measures of food insecurity related to the performance of multiple cognitive tasks (Verbal Learning, Verbal Recall, Visual Scanning, and Verbal Fluency), while controlling for key health and sociodemographic confounders using linear regression.

RESULTS

In descriptive analyses, respondents who experienced food insecurity in either early or late life performed significantly worse on all cognitive tasks when compared to the food secure. In models adjusted for health and sociodemographic confounders, early-life food insecurity predicted worse Verbal Learning performance and late-life food insecurity was associated with poorer Visual Scanning performance.

CONCLUSIONS

Food insecurity was related to poorer cognitive function in a nationally representative sample of older adults in Mexico. However, results suggested that the significance of effects depended on cognitive task and when in the life-course food insecurity was experienced.

Patient perceptions of the relationship between food insecurity and eating disorder treatment: A qualitative exploration

INTRODUCTION

Independently, food insecurity (FI) and binge-spectrum eating disorders (B-ED) are widespread problems; moreover, FI is associated with elevated binge-eating symptoms. However, extant research has not explored how FI may contribute to the development of B-ED symptoms, nor potential impacts of FI on eating disorder treatment.

METHOD

This study aimed to qualitatively examine (1) mechanisms by which FI impacts B-ED development and maintenance, (2) effects of past and/or present FI on ED treatment, and (3) participant recommendations for addressing FI in future B-ED treatment. Fourteen individuals who completed B-ED treatment and endorsed FI completed a 30-min interview about their experiences.

RESULTS

Participants reported that FI contributed to binge eating by maintaining dietary restraint-binge-eating cycle and by leading them to use food as a coping mechanism or for emotional comfort, both in past and present situations. Present FI interfered with treatment, particularly with adhering to treatment recommendations and food purchasing choices, however, participants did not report any impact of past FI on B-ED treatment. Participants reported that rarely was FI addressed as part of treatment; most participants suggested that future treatments work to (1) assess and problem solve present FI to minimize interference and (2) assess and understand the influence of past FI on current symptoms to validate the function of behavior.

DISCUSSION

These findings provide qualitative support that FI may reinforce B-ED symptoms and present FI may interfere with treatment. This study emphasizes the need for assessment and consideration of FI as a factor when treating individuals with B-EDs.

Food insecurity is associated with eating disorders independent of depression and anxiety: Findings from the 2020-2021 Healthy Minds Study

OBJECTIVE

To examine the association between food insecurity and eating disorder (ED) risk independent of co-occurring anxiety/depression.

METHOD

Data were provided by 121,627 undergraduate/graduate students who participated in the 2020-2021 Healthy Minds Study (HMS). Participants responded to questionnaire measures of food insecurity and risk for EDs, depression, and anxiety. Established cut-offs were used to identify students with food insecurity and probable psychopathology. Separate modified Poisson regressions adjusted for age, gender, race/ethnicity, and socioeconomic background examined the association between food insecurity and each form of psychopathology. The association between food insecurity and probable ED was then examined in a regression further adjusted for probable depression and anxiety.

RESULTS

Food insecurity was significantly associated with all three forms of psychopathology when examined separately (prevalence ratios ranged from 1.41 to 1.54, all p's < .001). When accounting for probable depression/anxiety, food insecurity was significantly associated with 1.19 times greater prevalence of a probable ED (p < .001).

DISCUSSION

The association between food insecurity and EDs was replicated in a large, national sample of university students. To our knowledge, this is the first study to examine the independence of this relationship after adjusting for depression/anxiety. This finding supports the hypothesis that specific mechanisms, rather than general psychological distress, likely underlie the food insecurity-ED relationship.

Food insecurity status is of added value in explaining poor health: a cross-sectional study among parents living in disadvantaged neighbourhoods in the Netherlands

OBJECTIVES

The aim of this study was to examine the added value of food insecurity in explaining poor physical and mental health beyond other socioeconomic risk factors.

DESIGN, SETTING, PARTICIPANTS AND OUTCOME MEASURES

Data for this cross-sectional study were collected using questionnaires with validated measures for food insecurity status and health status, including 199 adult participants with at least 1 child living at home, living in or near disadvantaged neighbourhoods in The Hague, the Netherlands. To assess the added value of food insecurity, optimism-corrected goodness-of-fit statistics of multivariate regression models with and without food insecurity status as a covariate were compared.

RESULTS

In the multivariable models explaining poor physical health (Physical Component Summary: PCS) and mental health (Mental Component Summary: MCS), from all included socioeconomic risk factors, food insecurity score was the most important covariate. Including food insecurity score in those models led to an improvement of explained variance from 6.3% to 9.2% for PCS, and from 5.8% to 11.0% for MCS, and a slightly lower root mean square error. Further analyses showed that including food insecurity score improved the discriminative ability between those individuals most at risk of poor health, reflected by an improvement in C-statistic from 0.64 (95% CI 0.59 to 0.71) to 0.69 (95% CI 0.62 to 0.73) for PCS and from 0.65 (95% CI 0.55 to 0.68) to 0.70 (95% CI 0.61 to 0.73) for MCS. Further, explained variance in these models improved with approximately one-half for PCS and doubled for MCS.

CONCLUSIONS

From these results it follows that food insecurity score is of added value in explaining poor physical and mental health beyond traditionally used socioeconomic risk factors (ie, age, educational level, income, living situation, employment status and migration background) in disadvantaged communities. Therefore, routine food insecurity screening may be important for effective risk stratification to identify populations at increased risk of poor health and provide targeted interventions.

Food Insecurity in the Food Allergic Population: A Work Group Report of the AAAAI Adverse Reactions to Foods Committee

Food allergies affect 32 million Americans. Restricted diets due to food allergies can be difficult to maintain especially when the household is food insecure. Food insecurity is defined as the inability to acquire food for household members due to insufficient money or resources for food. The COVID-19 pandemic has caused many people to face food insecurity for the first time with Latinx, Native American, and Black communities disproportionately affected. Because of the increase in food insecurity, this work group developed a survey regarding food insecurity screening. This survey was sent out to a random sample of American Academy of Allergy Asthma & Immunology members to assess food insecurity knowledge and practices. The majority of survey participants did not routinely screen their patients for food insecurity. The biggest barrier identified to screening was lack of knowledge of how to perform a screen and resources available when a patient screened positive. This work group report provides guidance on how to implement and perform a food insecurity screen, including federal resources and assistance programs.

Food insecurity and common mental disorders in perinatal women living in low socio-economic settings in Cape Town, South Africa during the COVID-19 pandemic: a cohort study

BACKGROUND

Common mental disorders (CMDs), i.e. depression and anxiety, are highly prevalent during the perinatal period, and is associated with poverty, food insecurity and domestic violence. We collected data from perinatal women at two time-points during the COVID-19 pandemic to test the hypotheses that (1) socio-economic adversities at baseline would be associated with CMD prevalence at follow-up and (2) worse mental health at baseline would be associated with higher food insecurity prevalence at follow-up.

METHODS

Telephonic interviews with perinatal women attending healthcare facilities in Cape Town, South Africa. Multivariable (multilevel) regression analysis was used to model the associations of baseline risk factors with the prevalence of household food insecurity and probable CMD at 3 months follow-up.

RESULTS

At baseline 859 women were recruited, of whom 217 (25%) were pregnant, 631 (73%) had given birth in the previous 6 months, 106 (12%) had probable CMD, and 375 (44%) were severely food insecure. At follow-up (n = 634), 22 (4%) were still pregnant, 603 (95%) had given birth, 44 (7%) had probable CMD, and 207 (33%) were severely food insecure. In the multivariable regression model, after controlling for confounders, unemployment [incidence rate ratio (IRR) 1.19 (1.12-2.27); p < 0.001] and had higher scores on the Edinburgh Postnatal Depression Scale [IRR 1.05 (1.03-1.09); p < 0.001] at baseline predicted food insecurity at follow-up; and experiencing domestic violence [OR 2.79 (1.41-5.50); p = 0.003] at baseline predicted CMD at follow-up.

CONCLUSIONS

This study highlights the complex bidirectional relationship between mental health and socio-economic adversity among perinatal women during the COVID-19 pandemic.

An Assessment of the Relationship of SNAP and Anemia Among School-Aged Children and Adolescents Living in Households With Food Insecurity

Children in food-insecure households have an increased risk of anemia. Participation in Supplemental Nutrition Assistance Programs (SNAP) has several benefits. However, it is unknown if it ameliorates anemia among school-aged children and adolescents living in food-insecure households. This study aims to assess the association of SNAP participation and anemia among children and adolescents living in households experiencing food insecurity. The sample population (n = 1635), aged 6 to 18 years, were pooled from the 2003–2014 National Health and Nutrition Examination Survey (NHANES). The exposure of interest was self-reported household SNAP participation. The outcome variable was the presence or absence of anemia, classified using the blood hematocrit concentration values. Survey weighted logistic regression was performed to calculate the odds ratio (OR) and 95% Confidence Interval (CI) of the association between participation in SNAP and anemia in food-insecure children. We found that over 80% of anemic children and adolescents, living in food-insecure households, participated in SNAP, while 63% of non-anemic children and adolescents, living in food-insecure households participated in SNAP (p = .007). Among children living in food-insecure households, SNAP participants had 3-fold increased odds of anemia compared to those who do not participate in SNAP, after adjusting for confounders (OR = 3.33, 95% CI: 1.25–8.88). In this study, SNAP participation was associated with increased odds of anemia in children and adolescents living in food-insecure households. Additional research is needed to assess if these unexpected findings are related to the adequacy of SNAP, affordability, and accessibility to healthy foods, or the household and individual food preferences in food-insecure households.

The association of COVID-19 vaccine availability with mental health among adults in the United States

OBJECTIVE

To assess whether COVID-19 vaccine approval and availability was associated with reduction in the prevalence of depression and anxiety among adults in the United States.

METHODS

We adopted cross sectional and quasi-experimental design with mental health measurements before vaccine availability (June 2020, N = 68,009) and after vaccine availability (March 2021, N = 63,932) using data from Census Pulse Survey. Depression and anxiety were derived from PHQ-2 and GAD-2 questionnaires. We compared rates of depression and anxiety between June 2020 and March 2021. Unadjusted and adjusted analysis with replicate weights were conducted.

RESULTS

Depression prevalence was 25.0% in June 2020 and 24.6% in March 2021; anxiety prevalence was 31.7% in June 2020 and 30.0% in March 2021 in the sample. In adjusted analysis, there were no significant differences in likelihood of depression and anxiety between June 2020 and March 2021.

CONCLUSION

Depression and anxiety were not significantly different between June 2020 and March 2021, which suggests that the pandemic effect continues to persist even with widespread availability of vaccines.

Food insecurity and mental health of college students in Lebanon: a cross-sectional study

The present study aimed to assess the prevalence of food insecurity (FI) among college students and explore its association with indicators of mental and psychosocial health. Data were collected using a cross-sectional online survey from college students in different universities in Lebanon during the Spring 2021 semester. FI was assessed using the validated eight-item food insecurity experience scale. The mental health of college students was assessed using validated screening tools for depression, anxiety and well-being, namely the Patient Health Questionnaire (PHQ-9), the General Anxiety Disorder-7 (GAD-7) and the World Health Organization (WHO-5) index, respectively. Multiple linear regression models were conducted to assess the relationship of FI with PHQ-9, GAD-7 and WHO-5 scores. A total of 745 students completed the online survey. Approximately 39 % of students in the sample were experiencing FI of which 27·4, 8·1, and 3·5 % were experiencing mild, moderate and severe FI , respectively. Low maternal education, low household monthly income and high levels of stress were significant correlates of FI among college students (P-trend < 0·001). In addition, 22·6 and 34·4 % of students showed severe symptoms of depression and anxiety, respectively. Regression models showed that FI was associated with higher scores on PHQ-9 and GAD-7 (β = 2·45; 95 % CI [1·41, 3·49]) and (β = 1·4; 95 % CI [1·1, 2·2], respectively) and lower scores on WHO-5 (β = −4·84; 95 % CI [−8·2, −1·5]). In conclusion, a remarkable proportion of college students reported experiencing different forms of FI, which was associated with poorer mental health and well-being outcomes. Public health programmes and interventions are needed to mitigate FI and improve student health-related outcomes.

Food insecurity, type 2 diabetes, and hyperglycaemia: A systematic review and meta-analysis

AIMS

Food insecurity (FIS) is a major public health issue with possible implications for type 2 diabetes mellitus (T2DM) risk. We conducted a systematic review and meta-analysis to explore the association between FIS and T2DM.

METHODS

We performed a systematic search in PubMed, Embase, Scopus, and Web of Science. All cross-sectional, peer-reviewed studies investigating the link between FIS and T2DM were included. Population characteristics, study sizes, covariates, T2DM diagnoses, and diabetes-related clinical measures such as fasting blood glucose (FBG) and HbA1c were extracted from each study. Outcomes were compared between food insecure and food secure individuals. Effect sizes were combined across studies using the random effect model.

RESULTS

Forty-nine peer-reviewed studies investigating the link between FIS and T2DM were identified (n = 258,250). Results of meta-analyses showed no association between FIS and clinically determined T2DM either through FBG or HbA1c: OR = 1.22 [95%CI: 0.96, 1.55], Q(df = 5) = 12.5, I2  = 60% and OR = 1.21 [95%CI: 0.95, 1.54], Q(df = 5) = 14; I2  = 71% respectively. Standardized mean difference (SMD) meta-analyses yielded no association between FIS and FBG or HbA1c: g = 0.06 [95%CI: -0.06, 0.17], Q(df = 5) = 15.8, I2  = 68%; g = 0.11 [95% CI: -0.02, 0.25], Q(df = 7) = 26.8, I2  = 74% respectively. For children, no association was found between FIS and HbA1c: g = 0.06 [95%CI: 0.00, 0.17], Q(df = 2) = 5.7, I2  = 65%.

CONCLUSIONS

Despite multiple proposed mechanisms linking FIS to T2DM, integration of the available literature suggests FIS is not associated with clinically determined T2DM or increases in FBG or HbA1c among adult patients.

Food Security, Financial Resources, and Mental Health: Evidence during the COVID-19 Pandemic

COVID-19 has negatively impacted many households’ financial well-being, food security, and mental health status. This paper investigates the role financial resources play in understanding the relationship between food security and mental health among U.S. households using data from a survey in June 2020. Results show job loss and savings draw down to pay for household bills had a significant relationship with both lower food security and greater numbers of poor mental health days during the pandemic.

Pathways by Which Food Insecurity Is Associated With Atherosclerotic Cardiovascular Disease Risk

Background Food insecurity (FI) has been associated with an increased atherosclerotic cardiovascular disease (ASCVD) risk; however, the pathways by which FI leads to worse cardiovascular health are unknown. We tested the hypothesis that FI is associated with ASCVD risk through nutritional/anthropometric (eg, worse diet quality and increased weight), psychological/mental health (eg, increased depressive symptoms and risk of substance abuse), and access to care pathways. Methods and Results We conducted a cross-sectional study of adults (aged 40-79 years) using the 2007 to 2016 National Health and Nutrition Examination Survey. Our primary exposure was household FI, and our outcome was 10-year ASCVD risk categorized as low (<5%), borderline (≥5% -<7.5%), intermediate (≥7.5%-<20%), and high risk (≥20%). We used structural equation modeling to evaluate the pathways and multiple mediation analysis to determine direct and indirect effects. Of the 12 429 participants, 2231 (18.0%) reported living in a food-insecure household; 5326 (42.9%) had a low ASCVD risk score, 1402 (11.3%) borderline, 3606 (29.0%) intermediate, and 2095 (16.9%) had a high-risk score. In structural models, we found significant path coefficients between FI and the nutrition/anthropometric (β, 0.130; SE, 0.027; P<0.001), psychological/mental health (β, 0.612; SE, 0.043; P<0.001), and access to care (β, 0.110; SE, 0.036; P=0.002) pathways. We did not find a significant direct effect of FI on ASCVD risk, and the nutrition, psychological, and access to care pathways accounted for 31.6%, 43.9%, and 15.8% of the association, respectively. Conclusions We found that the association between FI and ASCVD risk category was mediated through the nutrition/anthropometric, psychological/mental health, and access to care pathways. Interventions that address all 3 pathways may be needed to mitigate the negative impact of FI on cardiovascular disease.

Prevalence of food insecurity in people with major depression, bipolar disorder, and schizophrenia and related psychoses: A systematic review and meta-analysis

People with severe mental illness (SMI), such as major depression, bipolar disorder, and schizophrenia, experience numerous risk factors that may predispose them to food insecurity; however, the prevalence of food insecurity and its effects on health are under-researched in this population group. This systematic review and meta-analysis aimed to describe the prevalence and correlates of food insecurity in people with SMI. A comprehensive electronic search was conducted up to March 2021. Random effects meta-analysis was employed to determine the prevalence of food insecurity in SMI, and odds ratio (OR) of food insecurity in people with SMI compared to non-psychiatric controls/general population. Twenty-nine unique datasets (31 publications) were included. Prevalence estimate of food insecurity in people with SMI was 40% (95% CI 29-52%, I² = 99.7%, N = 27). People with SMI were 2.71 (95% CI 1.72-3.25) times more likely to report food insecurity than the comparator group (Z = 11.09, p < 0.001, I² = 95%, N = 23). The odds of food insecurity in SMI were higher in high/high-middle income countries compared to low/low-middle income countries, likely due to the high food insecurity rates in the general population of lower income countries. There was no difference in food insecurity rates by diagnosis. Food insecurity should be a consideration for health professionals working with community-dwelling people with SMI.

The prevalence and correlates of depression before and after the COVID-19 pandemic declaration among urban refugee adolescents and youth in informal settlements in Kampala, Uganda: A longitudinal cohort study

Purpose

There is scant research examining urban refugee youth mental health outcomes, including potential impacts of the COVID-19 pandemic. We examine prevalence and ecosocial risk factors of depression in the periods before and after the COVID-19 pandemic declaration among urban refugee youth in Kampala, Uganda.

Methods

Data from a cohort of refugee youth (n = 367) aged 16–24 years were collected in periods before (February 2020) and after (December 2020) the WHO COVID-19 pandemic declaration. We developed crude and adjusted generalized estimating equation logistic regression models to examine demographic and ecosocial factors (food insecurity, social support, intimate partner violence) associated with depression, and include time-ecosocial interactions to examine if associations differed before and after the pandemic declaration.

Results

The prevalence of depression was high, but there was no significant difference before (27.5%), and after (28.9%) the pandemic declaration (P = .583). In adjusted models, food insecurity (aOR: 2.54; 95% CI: 1.21–5.33) and experiencing violence (aOR: 2.53; 95% CI: 1.07–5.96) were associated with increased depression, and social support was associated with decreased depression (aOR: 0.85; 95% CI: 0.81–0.89).

Conclusions

These findings highlight the urgent need for interventions to address chronic depression, food insecurity, and ongoing effects of violence exposure among urban refugee youth in Kampala.

Global Mental Health and Nutrition: Moving Toward a Convergent Research Agenda

Both malnutrition and poor mental health are leading sources of global mortality, disease, and disability. The fields of global food security and nutrition (FSN) and mental health have historically been seen as separate fields of research. Each have undergone substantial transformation, especially from clinical, primary care orientations to wider, sociopolitical approaches to achieve Sustainable Development Goals. In recent years, the trajectories of research on mental health and FSN are further evolving into an intersection of evidence. FSN impacts mental health through various pathways such as food insecurity and nutrients important for neurotransmission. Mental health drives FSN outcomes, for example through loss of motivation and caregiving capacities. They are also linked through a complex and interrelated set of determinants. However, the heterogeneity of the evidence base limits inferences about these important dynamics. Furthermore, interdisciplinary projects and programmes are gaining ground in methodology and impact, but further guidance in integration is much needed. An evidence-driven conceptual framework should inform hypothesis testing and programme implementation. The intersection of mental health and FSN can be an opportunity to invest holistically in advancing thinking in both fields.

Association between the food security status and dietary patterns with polycystic ovary syndrome (PCOS) in overweight and obese Iranian women: a case-control study

Background

Polycystic ovary syndrome (PCOS), as one of the significant endocrine disorders, is common among women worldwide. Food insecurity (FI) and unhealthy dietary patterns can negatively affect reproductive health. The effects of the lifestyle modifications, especially dietary components, on PCOS are contradictory. The aim was the assessment of association between PCOS with food security status and dietary patterns among overweight or obese women.

Methods

This case-control study was performed on 240 overweight and obese women with and without PCOS (ratio 1:1) referred to the infertility clinic of Arash Hospital, Tehran, Iran. The general and socioeconomic characteristics, anthropometrics (weight, height, body mass index (BMI), waist circumference, hip circumference), physical activity, food security status, and dietary intakes (or patterns) were assessed using valid questionnaires, scales, stadiometer, and tape meter. The significant p-value was < 0.05.

Results

The prevalence of FI was 60% in women with PCOS and 30% in healthy women. PCOS risk was positively related to FI, quasi-western dietary patterns, low economic levels, waist circumference, and menstrual age and negatively with physical activity and healthy dietary patterns, even after controlling the potential confounders (P <  0.05). PCOS women had a higher intake of saturated fats, monounsaturated fats, oleic acid, fluorine, sucrose, and caffeine and a lower intake of vitamins A, B₅, B₆, B₁₂, C, and D, potassium, proteins, carbohydrates, cholesterols, docosahexaenoic acid, potassium, carotenes, lutein, beta-cryptoxanthin, lycopene, calcium, iron, thiamine, riboflavin, niacin, tetra- and dihydrofolate, biotin, phosphorus, magnesium, zinc, copper, fiber (total, insoluble, and crude), glucose, galactose, fructose, and lactose compared to the healthy women (P <  0.05).

Conclusions

FI, quasi-western dietary patterns, low economic levels, and waist circumference were significantly associated with the higher risk of PCOS. The lifestyle changes, especially dietary patterns, may be an essential strategy for reducing PCOS. Further studies are warranted to confirm these findings and to identify the underlying mechanisms.

Prevalence of food insecurity in community-dwelling people living with severe mental illness

AIM

The present study aimed to measure the prevalence and severity of food insecurity in people with a severe mental illness, defined as schizophrenia and related psychoses, and bipolar disorder; and explore relationships between food insecurity status, and sociodemographic and clinical characteristics.

METHODS

This cross-sectional study recruited community-dwelling people with severe mental illness receiving clozapine and/or a long-acting injectable antipsychotic medication within three mental health services in Sydney, Australia. Participants completed the 18-item Household Food Insecurity Access Scale. Sociodemographic and medical information was obtained from participants' medical records. Independent samples t-test and chi-square analyses were used to test for between group differences based on food insecurity status. Binary logistic regression analyses adjusting for age and gender were used to determine the odds ratio.

RESULTS

One-hundred and eighty-eight people completed the assessment: 63% were male, mean age was 49.2 ± 12.4 years, and the majority (85%) had a diagnosis of schizophrenia. Food insecurity was detected in 31% of participants. Of those who were food insecure, 12% were classified as severe, 13% as moderate and 7% as mild. Tobacco smoking was higher in food insecure people compared to food secure people (odds ratio = 3.1, 95% CI 1.3 to 7.1, p = 0.01). Food insecurity status was not associated with demographic, diagnostic or other clinical data.

CONCLUSIONS

Food insecurity is highly prevalent among community-dwelling people with severe mental illness receiving clozapine and/or long-acting injectable antipsychotic medication. Food security screening should be considered as routine care for this population group.

Tooth wear and socioeconomic status in childhood and adulthood: Findings from a systematic review and meta-analysis of observational studies

OBJECTIVES

To evaluate the association and level of evidence between socioeconomic status (SES) and tooth wear (TW) in children, adolescents, and adults.

DATA

Eligibility criteria comprised population-based observational studies assessing the association between SES and TW in permanent dentition of adolescents and adults. Interventional and descriptive studies or those without an internal comparison between exposed and nonexposed groups were excluded. The Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines were applied where applicable. Risk of bias (RoB) was assessed using the Newcastle-Ottawa scale. Meta-analyses were conducted to estimate the pooled effect measures. Q-statistic, I²statistic, subgroup and sensitivity analyses assessed study heterogeneity.

SOURCES

PubMed/Medline, Embase, Scopus, Web of Science, LILACS, SciELO, Cochrane Library, and Google Scholar databases were searched for articles published in English between 1st January 1980 and 31st March 2021.

RESULTS

Sixty-five studies were included, involving 63,893 participants in over 30 countries. A positive association was found between TW and education (OR=1.25 [0.96; 1.62]), family income (OR=1.18 [0.91; 1.53]), and private school (OR= 1.24 [0.90; 1.72]) among adolescents. Higher educated adults had a lower risk for TW (OR=0.70 [0.52; 0.93]). Most included studies had a moderate RoB. Limitations relating to population representation and assessment methodologies were identified in the included studies.

CONCLUSIONS

SES was associated with TW with its direction depending on the individuals' age. The overall quality of evidence was moderate.

CLINICAL SIGNIFICANC

SES should be included as part of the routine screening and risk assessment for tooth wear.

Food Insecurity and Sleep Disturbance Among 223,561 Adolescents: A Multi-Country Analysis of Cross-Sectional Surveys

This study was to investigate the association between food insecurity (FI) and sleep disturbance among adolescents. Based on the cross-sectional data of the Global School-based Student Health Survey, this study analyzed self-reported data from adolescents in 68 countries. Multivariate logistic regression and meta-analysis were used to evaluate the association between FI and sleep disturbance. The final sample included 223,561 adolescents. The prevalence of severe FI and sleep disturbance was 6.4% and 8.0%, respectively. Severe FI was significantly associated with a higher risk of sleep disturbance in 48 of the 68 countries after adjusting for covariates, with a pooled OR (95% CI) of 1.94 (1.79-2.09). Overall, the association between FI and sleep disturbance was similar across countries and gender, though a large level of heterogeneity existed across upper- and middle-income countries. Identifying adolescents suffering from FI and remedying the FI severity may be important to improve sleep quality in global adolescents.

Examining the associations between food worry and mental health during the early months of the COVID-19 pandemic in Canada

OBJECTIVE

Little is known about the association between mental health and diminished food worry during the COVID-19 pandemic. This paper examines worry about having enough food to meet household needs and its association with mental health during the early months of the pandemic in Canada.

METHODS

Data are drawn from the first round of a multi-round mental health monitoring survey. Online surveys were administered between May 14 and 29, 2020, to a nationally representative sample of Canadian adults (n = 3000). Logistic regression models were used to examine associations between food worry and mental health indicators (anxious/worried, depressed, worse mental health compared with pre-pandemic, and suicidal thoughts/feelings), after adjusting for socio-demographic characteristics and pre-existing mental health conditions. Fully adjusted models explored the impact of controlling for financial worry due to the pandemic in the previous 2 weeks.

RESULTS

Overall, 17.3% of the sample reported food worry due to the pandemic in the previous 2 weeks, with the highest prevalence found among those with a reported disability (29.3%), Indigenous identity (27.1%), or pre-existing mental health condition (25.3%). Compared with participants who did not report food worry, those who did had higher odds of reporting feeling anxious/worried (OR=1.36, 95% CI: 1.08-1.71) and suicidal thoughts/feelings (OR=1.87, 95% CI: 1.24-2.80) when controlling for socio-demographics, pre-existing mental health conditions, and financial worry.

CONCLUSION

This paper provides insights about the associations between food worry and mental health in Canada during the COVID-19 pandemic and indicates the need for improved policies and social supports to mitigate food worry and associated mental health outcomes.

Facemask and Respirator in Reducing the Spread of Respiratory Viruses; a Systematic Review

Introduction

Respiratory viruses spread fast, and some manners have been recommended for reducing the spread of these viruses, including the use of a facemask or respirator, maintaining hand hygiene, and perfoming social distancing. This systematic review aimed to assess the impact of facemasks and respirators on reducing the spread of respiratory viruses.

Methods

We conducted a systematic review using MeSH terms, and reported findings according to PRISMA. PubMed, Embase, Cochrane Library, Scopus, ProQuest, Web of Science(WoS), and Google Scholar were searched for articles published between 2009 and 2020. Two independent reviewers determined whether the studies met inclusion criteria. The risk of bias of studies was assessed using Newcastle-Ottawa (NOS) and Consolidated Standards of Reporting Trials (CONSORT).

Results

A total of 1505 articles were initially retrieved and 10 were finally included in our analysis (sample size: 3065). 96.8% of non-infected participants used facemask or respirator in contact with people infected with a respiratory virus, facemask and respirator have a significant effect on reducing the spread of respiratory viruses.

Conclusion

Evidence support that using a facemask or respirator can reduce the spread of all types of respiratory viruses; therefore, this result can be generalized to the present pandemic of a respiratory virus (SARS-COV-2) and it is recommended to use a facemask or respirator for reducing the spread of this respiratory virus.

The Food Equity and Environmental Data Sovereignty (FEEDS) Project: Protocol for a Quasi-Experimental Study Evaluating a Digital Platform for Climate Change Preparedness

Background

Despite having the tools at our disposal to enable an adequate food supply for all people, inequities in food acquisition, distribution, and most importantly, food sovereignty, worsen food insecurity. The detrimental impact of climate change on food systems and mental health is further exacerbated by a lack of food sovereignty. We urgently require innovative solutions to enable food sovereignty, minimize food insecurity, and address climate change–related mental distress (ie, solastalgia). Indigenous communities have a wealth of Traditional Knowledge for climate change adaptation and preparedness to strengthen food systems. Traditional Knowledge combined with Western methods can revolutionize ethical data collection, engagement, and knowledge mobilization.

Objective

The Food Equity and Environmental Data Sovereignty (FEEDS) Project takes a participatory action, citizen science approach for early detection and warning of climate change impacts on food sovereignty, food security, and solastalgia. The aim of this project is to develop and implement a sustainable digital platform that enables real-time decision-making to mitigate climate change–related impacts on food systems and mental well-being.

Methods

Citizen science enables citizens to actively contribute to all aspects of the research process. The FEEDS Project is being implemented in five phases: participatory project planning, digital climate change platform customization, community-led evaluation, digital platform and project refinement, and integrated knowledge translation. The project is governed by a Citizen Scientist Advisory Council comprising Elders, Traditional Knowledge Keepers, key community decision makers, youth, and FEEDS Project researchers. The Council governs all phases of the project, including coconceptualizing a climate change platform, which consists of a smartphone app and a digital decision-making dashboard. Apart from capturing environmental and health-related big data (eg, weather, permafrost degradation, fire hazards, and human movement), the custom-built app uses artificial intelligence to engage and enable citizens to report on environmental hazards, changes in biodiversity or wildlife, and related food and mental health issues in their communities. The app provides citizens with valuable information to mitigate health-related risks and relays big data in real time to a digital dashboard.

Results

This project is currently in phase 1, with the subarctic Métis jurisdiction of Île-à-la-Crosse, Saskatchewan, Canada.

Conclusions

The FEEDS Project facilitates Indigenous Peoples’ self-determination, governance, and data sovereignty. All citizen data are anonymous and encrypted, and communities have ownership, access, control, and possession of their data. The digital dashboard system provides decision makers with real-time data, thereby increasing the capacity to self-govern. The participatory action research approach, combined with digital citizen science, advances the cocreation of knowledge and multidisciplinary collaboration in the digital age. Given the urgency of climate change, leveraging technology provides communities with tools to respond to existing and emerging crises in a timely manner, as well as scientific evidence regarding the urgency of current health and environmental issues.
