Food insecurity and depressive symptoms of older adults living alone in South Korea

Influence of health food literacy on willingness to pay for healthier foods: focus on food insecurity

BACKGROUND

The repercussions of food insecurity are widely recognized to negatively impact overall health and are influenced by a complex interplay of physiological, psychological, social, and environmental factors.

METHODS

This study examined the disparities in food consumption and literacy between among food security households and food insecurity households using data from the Korea Rural Economic Institute's 2022 Consumer Behavior Survey for Food, which involved 3,321 respondents.

RESULTS

Food security households had a greater understanding of and better attitude toward healthier food choices than food insecurity households. Economic ability was identified as having the most significant association with food purchasing behavior, with food security households spending more on average than food insecurity households. Structural equation modeling demonstrated the association of knowledge and attitude with dietary implementation and underscored the significance of consumer literacy as a factor related to willingness to pay for healthier foods.

CONCLUSIONS

This study underscores the intertwined relationships among financial capacity, knowledge, and health-conscious dietary choices. It also suggests the need for targeted interventions addressing economic and educational gaps to foster healthier food consumption patterns across different socioeconomic contexts.

"It's just a constant concern in the back of my mind": Lived experiences of college food insecurity

Objective: Food insecurity is a growing concern to the health and wellbeing of college students. This study aims to examine the lived experiences of students at-risk of food insecurity and associated challenges in a public urban campus. Participants: The study recruited 21 college students at risk of food insecurity using purposive sampling. Methods: We performed qualitative interviews with three focus groups and conducted a thematic analysis to explore themes that emerged from participant discussions. Results: Three central themes emerged from our qualitative analysis: (a) barriers to accessing stable and healthy food; (b) impacts of food insecurity on academic performance and physical and mental health; and (c) coping strategies for navigating food insecurity. Conclusions: The study highlights the distinct natures of food hardship and responses specific to urban public college students. Suggestions for academics and college administrators to mitigate college food insecurity are discussed.

Food insecurity and unmet healthcare needs in South Korea

BACKGROUND

Food insecurity is a significant risk factor for chronic and infectious diseases. It is also a barrier to accessing healthcare because food insecurity tends to co-occur with other socioeconomic disadvantages. The objective of this study is to examine whether food insecure individuals in South Korea can access desired level of healthcare when needed.

METHODS

This repeated cross-sectional study used data from the 2013-2015 and 2019-2021 waves of the Korean National Health and Nutrition Examination Survey. Multivariable logistic regression models were used to examine the association between household food insecurity and two indicators of unmet healthcare needs - any experience of forgoing medical service and the reasons for unmet needs (problems with availability, acceptability, and accessibility). Covariates indicating predisposing, enabling, and need factors were included in the regression analyses.

RESULTS

Of the 19,394 participants aged 19-64 years, 4.5% were moderately food insecure, 0.9% were severely food insecure, and 9.3% reported unmet healthcare needs. In the adjusted model, moderate food insecurity (OR, 1.47; 95% CI, 1.19-1.82) and severe food insecurity (OR, 3.32; 95% CI, 2.27-4.85) were associated with higher odds of unmet healthcare needs in a dose-graded manner. These associations were largely due to the increased odds of accessibility-related unmet needs among participants with moderate (OR, 2.31; 95% CI, 1.68-3.19) and severe food insecurity (OR, 6.15; 95% CI, 3.91-9.68).

CONCLUSIONS

Food insecurity was associated with higher odds of unmet healthcare needs among Korean adults. Competing life demands may have a cumulative impact on health over the short and long term. Efforts to address trade-offs between healthcare needs and food insecurity may improve the health and well-being of marginalized populations.

Longitudinal Associations Between Food Insecurity and Suicidal Ideation Among Adults Aged ≥65 in the Korean Welfare Panel Study

Objectives : This study aimed to explore longitudinal associations between food insecurity and suicidal ideation, and the moderating roles of intervention programs. Methods: Data were derived from the 2012-2019 waves of the Korean Welfare Panel Study. Participants aged ≥65 at baseline (n = 4,425) and their annual follow-up measurements for a mean of 6.58 years were included. Conditional fixed effects logistic regressions were used to test 1) associations between food insecurity and the onset of suicidal ideation; 2); whether associations were attenuated by food assistance and income support programs. Results: Food insecurity was associated with higher odds of suicidal ideation in the full sample (OR, 1.77; 95% CI, 1.37-2.29), among women (OR, 1.67; 95% CI, 1.24-2.26) and men (OR, 2.06; 95% CI, 1.25-3.40). The association between food insecurity and suicidal ideation was attenuated by participation in home-delivered meal services (OR, 0.43; 95% CI, 0.21-0.88). Conclusion: Food insecure older adults were more likely to consider committing suicide than their food secure counterparts. Food assistance through home-delivered meal services, but not other intervention programs, could weaken this link.

Mental Health, Food Insecurity, and Economic Hardship among College Students during the COVID-19 Pandemic

The mental health crisis among college students has become one of the most pressing issues, especially during the pandemic. Researchers discuss food insecurity as one of the leading causes of mental distress. The onset and continued impacts of the COVID-19 pandemic appear to compound food insecurity, economic hardship, and mental health. This study aims to understand the mental health of college students in relation to food insecurity and financial struggles to meet basic living expenses and debts during the pandemic. Authors collected survey data from college students in a public urban university in 2020 and conducted a multiple regression (N = 375). Evidence indicated that mental health became significantly worse after the pandemic onset. Mental health was significantly associated with food insecurity and multiple economic hardships, controlling for prepandemic mental health and other characteristics. The findings affirm that food insecurity and dire levels of economic hardship have devastating effects on the mental health of young adults. The article highlights the long-term implications of mental health affected by basic needs insecurity and the emergent need for integrated services and university-community partnerships.

Association between food insecurity and perceived stress among older adults (50+) in six low- and middle-income countries

OBJECTIVES

In this study, we assess the relationship between food insecurity andperceived stress among older adults (50+) in six low- and middle-income countries of China, Ghana, India, Mexico, Russia and, South Africa.

METHODS

Cross-sectional comparative analysis was conducted using nationally representative data from the WHO's Study on global AGEing and adult health survey. Bivariate and multivariate regression analyses examine if food insecurity was associated with perceived stress. We also examined the mediating role of health conditions on the association between food insecurity and perceived stress.

RESULTS

Across countries, the mean perceived stress score was higher among the older population with food insecurity. Regression analysis showed significant and positive association between food insecurity and perceived stress. Findings from the pooled data of six countries showed, older adults who experienced severe food insecurity (β = 4.05, p < .001) had higher perceived stress scores. The association was statistically significant in India, Russia, South Africa, and Ghana.

CONCLUSION

Food insecurity showed significant adverse impact on perceived stress among the older population in low- and middle-income countries. Policy measures to reduce household food insecurity are important for improving both mental and physical health conditions of the growing older population in low- and middle-income countries.

Material Hardships, Perceived Stress, and Health among Low-Wage Hospital Workers

Many service, clerical, and technical hospital workers deemed essential during the pandemic have wages that do not reflect the essential nature of their work and do not earn enough income to cover basic expenses. Thus, many experience material hardships related to food, housing, and medical care. Previous studies have shown strong relationships between material hardships and health; however, they do not fully explain the role of stress as an intervening mechanism. This cross-sectional study analyzes an online survey with 257 lower-wage hospital workers to examine the relationships between hardships and health, and how perceived stress mediates these relationships. Path analysis revealed that financial and food hardships were related to mental health through perceived stress, while medical hardship was directly associated with physical health. These findings add to the evidence that workers' hardships either directly or indirectly contribute to negative mental and physical health outcomes through perceived stress. Future investigations should further examine relationships among material hardships, stress, and health, and advocacy efforts should focus on raising wages for essential hospital workers.

Comparison of Dietary Behaviors and the Prevalence of Metabolic Syndrome in Single- and Multi-Person Households among Korean Adults

Changes in household dynamics in Korea, such as the transition from multi- to single-person households, have led to changes in individuals' dietary behavior patterns and health status. Thus, this study aimed to compare dietary behaviors and determine the prevalence of metabolic syndrome (MetS) as well as explore factors associated with MetS according to household type among Korean adults. Using data from the Korea National Health and Nutrition Examination Survey 2014-2018, we included 21,944 Korean adults with available health examination and dietary recall data. Based on self-reported information, individuals were divided into two household types: single- and multi-person households. We used multivariable logistic regression to estimate the adjusted odds ratios (AORs) and 95% confidence intervals (CIs) for MetS and its components after adjusting for potential covariates. Among the study population, 9.19% and 90.81% lived in single-person and multi-person households, respectively. Individuals in single-person households had a higher energy intake overall and a greater percentage of energy from animal protein; total, saturated, and monounsaturated fats; and animal source foods and a lower percentage of energy from carbohydrates, plant protein, and plant source foods than those from multi-person households (all, p < 0.05). Individuals living in single-person rather than multi-person households were more likely to consume milk/dairy products, alcoholic and non-alcoholic beverages, oils/fats, and others but were less likely to consume vegetables/mushrooms, fruits, seaweeds, and fish/shellfish (all, p < 0.05). Living alone was associated with higher energy intake from main meals and foods prepared away from home but a lower dietary variety score and fewer total main meals consumed (all, p < 0.05). Skipping breakfast, frequent eating out, food insecurity, and MetS combination phenotypes significantly differed by household type. Individuals living alone had higher odds of MetS (AOR: 1.14, 95% CI: 1.02-1.29), abdominal obesity (AOR: 1.14, 95% CI: 1.01-1.28), elevated blood pressure (AOR: 1.28, 95% CI: 1.12-1.47), and elevated fasting blood glucose (AOR: 1.18, 95% CI: 1.05-1.33) than those living with others. Compared with those in multi-person households, individuals in single-person households tend to have health and dietary behaviors that increase vulnerability to MetS; therefore, establishing health care strategies and nutrition policies according to household type is necessary.

Food security and food practices in later life: a new model of vulnerability

The older population is particularly susceptible to malnutrition, which currently affects 1.3 million people aged 65+ in the United Kingdom. Malnutrition is an outcome of food insecurity and despite demographic changes that have led to a rise in numbers of older people, we know very little about how older people become vulnerable to food insecurity. The aim of this study was therefore to explore older people's everyday food practices in order to expose the strengths and challenges within local and national food systems, and better understand how food insecurity might arise in later life. This empirical study operationalised practice theory using a multi-method ethnographic approach with 25 households aged 60–94 years, comprising interviews, observation, visual methods and food logs. A model of vulnerability developed by Schröder-Butterfill and Marianti framed data collection and analysis. Analysis revealed the assets and adaptations older households used to protect themselves from threats to food security. Factors ranging from changes to physical and mental health, and structural factors such as supermarket design, moved households towards food insecurity. Smaller everyday ‘trivia’, e.g. lack of seating and accessible toilets in supermarkets, accumulated to shift people towards vulnerability. Vulnerability is structured by the habitus but is a fluid, relational, temporal and socially constructed state, and people moved towards and away from vulnerability. We have developed a model that accommodates this fluidity, incorporates the concept of ‘cumulative trivia’ and suggests how the ‘aggregation of marginal gains’ could counter-balance and address trivial threats. This model demonstrates to policy makers and those working in public health how vulnerability to food insecurity operates and where interventions could be applied to support households to achieve food security and avoid becoming malnourished.

Determinants of food insecurity among elderly people: findings from the Canadian Community Health Survey

Food insecurity among elderly people is a major public health concern due to its association with several health conditions. Despite growing research and implementation of diverse income-based policy measures, food insecurity among elderly people remains a major policy issue in Canada. Additional research could inform food policy beyond strategies that target improving the financial resources of elderly people. Drawing data from the Canadian Community Health Survey (N = 24,930), we explored the correlates of food insecurity among older adults using negative log-log logistic regression techniques. Our findings show that certain categories of elderly people are more prone to food insecurity. These segments include seniors who are visible minorities (OR = 1.29, p < 0.01), live alone (OR = 1.13, p < 0.05), have a very weak sense of community belonging (OR = 1.40, p < 0.001), in poor physical health (OR = 1.20, p < 0.01), and those in lower age and income categories. These findings corroborate previous studies that demonstrate that food insecurity among elderly people is a complex phenomenon influenced by diverse socio-economic factors. In Canada, food security policies targeted at elderly people have largely prioritised poverty alleviation through income support programmes. While these programmes can improve the purchasing power of elderly people, they may not be sufficient in ensuring food security. There is a need to embrace and further investigate an integrated approach that pays attention to other contextual socio-economic dynamics.

Food Security Status is not Associated with Increased Risk of Metabolic Syndrome in Korean Adults

Background: It is still uncertain whether food insecurity increases the risk of metabolic syndrome. Recent reports from the United States and developing countries have shown conflicting results on this issue. This study aimed to investigate the association between food security status and metabolic syndrome in Korean adults. Methods: We performed a nationwide population study using data for 18,782 adults obtained from the 2012 to 2015 Korean National Health and Nutrition Examination Surveys. The 18-item Food Security Survey Module was utilized to assess household food security status. We used multiple logistic regression models to determine the association between food security status and metabolic syndrome. Results: The overall prevalence of food insecurity was 8.2% and that of metabolic syndrome was 27.3%. The prevalences of metabolic syndrome were 26.2%, 32.3%, 30.2%, and 28.8% in the high, marginal, low, and very low food security groups, respectively. Food-insecure participants (participants in the low food security and very low food security groups) were significantly more likely to be female, divorced/widowed/separated, and current smokers compared to food-secure participants. Food-insecure participants also had lower incomes, lower education attainments, and lower physical activities (P < 0.05). Compared with the high food security group, the marginal (odds ratio [OR]: 1.34, 95% confidence interval [95% CI]: 1.19-1.50, P < 0.001) and low food security groups (OR: 1.22, 95% CI: 1.04-1.42, P = 0.01) had increased odds of metabolic syndrome in the unadjusted models. However, after controlling for covariates, including age, sex, marital status, education attainment, household income, smoking, alcohol intake, and physical activity, neither marginal food security (adjusted odds ratio [aOR]: 1.02, 95% CI: 0.87-1.19, P = 0.86) nor low food security (aOR: 0.88, 95% CI: 0.71-1.08, P = 0.22) was significantly associated with an increased risk of metabolic syndrome. Conclusions: Contrary to a prior report from the United States, food security status was not significantly associated with the risk of metabolic syndrome in Korean adults.

Examining associations of food insecurity with major depression among older adults in the wake of the Great Recession

As a psychosocial stressor, the degree to which food insecurity impacts major depression may be dependent on macro-level context, which can be examined in the wake of the Great Recession. The objective of this study was to determine (1) whether food insecurity transition status (i.e. initially food insecure, becoming food insecure, and remaining food insecure vs. not food insecure) was associated with major depression in older adults and; (2) whether this association was moderated by macro-level context. Data came from the United States Health and Retirement Study, 2008-2016. Multivariable logistic regression across all years revealed that major depression was associated with any exposure to food insecurity, however; this association was moderated by time period. Remaining food insecure was associated with major depression during all time periods. In contrast, becoming food insecure was associated with major depression in the years during and immediately following the Recession, but not in later time periods. Findings suggest that associations of food insecurity with major depression among older adults are moderated by macro-level context, consistent with theories of social comparison and relative disadvantage. Food insecurity may represent an important risk factor for major depression and mental health disparities across socioeconomic strata in old age. Thus, policies that increase access to food assistance programs or improve the quality of local food environments may buffer against the impact of food insecurity on depression and associated complications among older adults.
