This chapter delves into the severe health impacts of climate change, focusing on issues such as heat stress, infectious diseases, and food insecurity. Medical doctor Sweta Koirala from Nepal shares insights on increasing heat-related illnesses and the spread of vector-borne diseases such as dengue fever. The chapter highlights the critical need for climate adaptation measures to protect human health, emphasizing the vulnerability of agricultural systems and labour productivity. Personal stories, such as those of outdoor workers facing extreme heat in Bangladesh, illustrate the direct effects on daily life and economic stability. The CVF’s Monitor and the Lancet the Lancet Countdown’s works on Health...’s works on Health and Climate Change address the interplay between climate adaptation, public health, and agricultural productivity, stressing the urgent need for comprehensive health and food security policies to mitigate these impacts.
Little is known about food insecurity in Asian Americans (AAs). We examined age/ethnic subgroup differences in food insecurity among AAs in California.
Design:
We examined associations between food insecurity and sociodemographic characteristics among AAs (Chinese, Filipino, Korean, Vietnamese) using the Chi-square test. Rolling averages were calculated to examine food insecurity trends.
Setting:
California
Participants:
We used data from the California Health Interview Survey (2011-2018) for AAs categorized by age (18-39, 40-59, 60+ years).
Results:
Food insecurity prevalence varied by subgroup, with the highest observed in older adult (aged 60+) Vietnamese (26%). Between 2011-14 and 2015-18, food insecurity prevalence increased 20-45% across older adults, but showed a decreasing trend among younger adults. Being foreign born and speaking a language other than English at home were associated with increased food insecurity.
Conclusions:
Community-engaged research to develop culturally appropriate strategies for mitigating food insecurity among older AAs is warranted.
During the global recession of 2020 food insecurity increased substantially in many countries around the world. Fortunately, the surge in food insecurity quickly came to a halt as the world economy returned to its positive growth path, despite double-digit domestic food inflation in most countries. To shed light on the relative importance of income growth and food inflation in driving food insecurity, we employ a heterogeneous-agent model with income inequality, complemented by novel cross-country data for the period 2001–2021. We use external instruments (changes in commodity terms-of-trade, external economic growth, and harvest shocks) to isolate exogenous variation in domestic income growth and food inflation. Our findings suggest that income growth is the dominant driver of annual variations in food insecurity, while food price inflation plays a somewhat smaller role, aligning with our model predictions.
This paper contends that the intractability of food insecurity as a social policy issue may have arisen in part because food access has become central to the interpretation of what is required to be food secure. We revisit key features of the evolution of the right to food and examine developments in the instruments used to monitor right to food progress. We articulate how the materiality of food access has come to the forefront of food systems policy, within which food insecurity is embedded but its structural underpinnings are lost. In turn, civil society food-based responses to growing food insecurity prevalence prevail. The pre-eminence of objectified food access as a socio-political orientation to food insecurity has refabricated the social problem of food need. A conscious uncoupling of food access from how we study and respond to food insecurity is needed to re-design food insecurity policy that is grounded in poverty alleviation.
Shifts in food acquisition during the COVID-19 pandemic may have affected diet. Assessing changes in diet is needed to inform food assistance programs aimed at mitigating diet disparities during future crises. This longitudinal study assessed changes in diet among a low-income, racially diverse population from March-November 2020.
Methods
Survey data were collected from 291 adults living in Austin, TX. Multivariable ordinal logistic regression models assessed the relationship between changes in consumption of fresh, frozen, and canned fruits and vegetables (FV), and sugar-sweetened beverages (SSBs) and the following food acquisition factors: food security, difficulty finding food, food bank usage, and food shopping method.
Results
Adjusted models indicated individuals with consistent food insecurity had increased odds of reporting a higher category of consumption for frozen (aOR = 2.13, P < 0.05, CI:1.18-3.85) and canned (aOR = 4.04, P < 0.01, CI:2.27-7.20) FV and SSB (aOR = 3.01, P < 0.01, CI:1.65-5.51). Individuals who reported using a food bank were more likely to report increased consumption of frozen (aOR = 2.14, P < 0.05, CI:1.22-3.76) and canned FV (aOR = 2.91, P < 0.01, CI:1.69-4.99).
Conclusions
Shifts in food acquisition factors were associated with changes in diet. Findings demonstrate the need for more robust food assistance programs that specifically focus on all dimensions of food security.
A Rank Forum was convened to discuss the evidence around food insecurity (FIS), its impact on health, and interventions which could make a difference both at individual and societal level, with a focus on the UK. This paper summarises the proceedings and recommendations. Speakers highlighted the growing issue of FIS due to current economic and social pressures. The health implications of FIS vary geographically since food insecure women in higher income regions tend to be living with overweight or obesity, in contrast to those living in low-to-middle-income countries. This paradox could be due to stress and/or metabolic or behavioural responses to an unpredictable food supply. The gut microbiota may play a role given the negative effects of low fibre diets on bacterial diversity. Solutions to FIS involve individual behavioural change, targeted services and societal/policy change. Obesity-related services are currently difficult to access. Whilst poverty is the root cause of FIS, it cannot be solved solely by making healthy food cheaper due to ingrained beliefs, attitudes and behaviours in target groups. Person-centred models, such as Capability-Opportunity-Motivation Behavioural Change Techniques and Elicit-Provide-Elicit communication techniques, are recommended. Societal change or improved resilience through psychological support may be more equitable ways to address FIS. They can combine with fiscal or food environment policies to shift purchasing towards healthier foods. Policy implementation can be slow to enact due to the need for strong evidence, consultation and political will. Eradicating FIS must involve co-creation of interventions and policies to ensure a consensus on solutions.
This study investigates the links between dietary diversity, food insecurity and mental health (depression and anxiety) in adolescents from rural Pakistan. Adolescence is a critical time for developing mental health disorders, yet limited research exists on these issues in low- and middle-income countries (LMICs).
Methods
The study included 1,396 adolescents (ages 9–15) and assessed their mental health, nutrition and maternal well-being. Depression and anxiety were measured using standardized questionnaires, while dietary diversity and food insecurity were evaluated through household assessments. Incidence rate ratios assessed the relationship between nutrition and mental health.
Results
Results showed that 8.1% of boys and 10.2% of girls experienced depression, with anxiety rates ranging from 5.8% to 39.1%. Adolescents from households with higher dietary diversity had lower symptoms of depression and anxiety (IRRs:0.91–0.96), while those with higher food insecurity had increased symptoms (IRRs:1.24–1.86). Folate deficiency was associated with depressive symptoms, particularly in boys. Maternal mental health was observed to mediate the relationship between food insecurity and adolescent depression and anxiety.
Conclusions
The study highlights that improving maternal mental health and addressing nutritional deficiencies, particularly folate, may benefit adolescent well-being. Further research in other LMICs is needed to explore these associations and their mechanisms.
Young adulthood is a transitional period between childhood and adulthood characterised by unique stressors that increase the risk of food insecurity and poor mental health. This study examined the association between food insecurity and mental health outcomes among U.S. young adults aged 18–25.
Design:
A cross-sectional survey was completed by young adults between the ages of 18 and 25 years between January and April 2022. Key measures included food insecurity, perceived stress, anxiety, depressive symptoms and insomnia. Descriptive statistics and linear regression analyses were used to determine the prevalence of and associations between food insecurity and mental health outcomes, controlling for key demographic and social factors.
Setting:
Online survey.
Participants:
1630 U.S. young adults.
Results:
Among the analytic sample of 1041 young adults, nearly 70 % of participants identified as being food insecure in the last year. Participants reported moderate to high levels of perceived stress, anxiety, depressive symptoms and insomnia. Food insecurity was positively associated with each mental health outcome including perceived stress (β = 2·28, P< 0·01), anxiety (β = 2·84, P< 0·01), depressive symptoms (β = 2·74, P< 0·01) and insomnia (β = 1·28, P< 0·01) after controlling for all other factors.
Conclusion:
Food insecurity is associated with mental health problems among young adults. Future efforts should explore the directionality of this relationship to determine if food insecurity initiates or exacerbates poor mental health outcomes or if poor mental health contributes to food insecurity. Interventions to improve food security status may also help support mental health among young adults.
Food insecurity (FIS) is a critical public health issue, particularly among older adults. This study investigates the association between FIS with diet quality and anthropometric indices in the US older adults. A cross-sectional analysis was conducted using NHANES data from 2017 to 2020, involving 2592 participants aged ≥ 60 years. FIS was assessed using the USDA Household Food Security Survey Module. Diet quality was assessed using the Healthy Eating Index (HEI)-2020 and adherence to Mediterranean diet (MedDiet) score. Anthropometric measures were calculated following standardised protocols. Multivariable logistic regression models, adjusted for demographic, socio-economic and behavioural factors examined the association between FIS and the higher quartile and tertile of anthropometric and diet quality indices, respectively. Of the participants, 27·4 % experienced FIS. FIS participants were younger and had lower education and income levels compared with FS individuals (P < 0·05). In the adjusted model, FIS was associated with lower adherence to both the Mediterranean Diet (OR: 0·48, 95 % CI: 0·31, 0·67) and HEI-2020 (OR: 0·61, 95 % CI: 0·37, 0·84), indicating poorer diet quality in older adults. In adjusted analyses, FIS was significantly associated with higher A Body Shape Index quartiles (Q3: OR: 1·44, 95 % CI: 1·06, 1·95; Q4: OR: 1·46, 95 % CI: 1·07, 2·01), the waist-to-hip ratio (Q4: OR: 1·44, 95 % CI: 1·01, 2·06) and the Conicity index (Q4: OR: 1·36, 95 % CI: 1·02, 1·81). FIS in older adults is associated with unfavourable diet quality and body composition patterns, particularly central obesity measures. Addressing FIS may mitigate health risks related to obesity and its complications.
In the United States, roughly one million pregnancies occur every year from the misuse and discontinuation of oral contraceptives – which may be affected by an individual’s exposure to social determinants of health (SDOH). For those experiencing poorer SDOH, significant barriers may exist when family planning. Thus, our primary objective is to examine associations between domains of SDOH and contraceptive use as well as pregnancy intention using the Behavior Risk Factor Surveillance System (BRFSS).
Methods:
A cross-sectional analysis of 2017 BRFSS was conducted using the SDOH module to examine differences in family planning. We used bivariate and multivariable logistic regression models to measure associations, via odd ratios, between SDOHs and contraceptive use and pregnancy intention controlling for other sociodemographic variables.
Results:
We found that individuals experiencing negative SDOH who reported running out of food (AOR: 0.65; CI: 0.50-0.86), were unable to afford balanced meals (AOR: 0.64; CI:0.49-0.84), or had no money left at the end of the month (AOR: 0.45; CI: 0.32-0.64) were less likely to have used contraceptive methods compared to those not experiencing challenges within these SDOH domains. Among women not utilizing contraceptive methods, individuals not intending to get pregnant were more likely to report difficulty affording balanced meals or having financial stability compared to women attempting to become pregnant.
Conclusions:
Our study found that the SDOH domains of monthly financial instability and food insecurity are significantly associated with women not using contraceptive measures but not wanting to become pregnant. Addressing barriers to contraceptive access and FP is becoming more important with shifting policies regarding women’s reproductive healthcare. For women seeking contraceptive and FP advice, increased funding may help provide a solution.
Social determinants of health are nonmedical factors that influence health outcomes. They have a direct impact on maternal morbidity and mortality. There are five domains considered in the umbrella of social determinents of health. This case represents an example of food and housing insecurity for a patient who presents for prenatal care. Important collaboration with social work and local resources are critical for those who provide prenatal care for patients. The case reviews assessment of social determinants of health, approach to resources, and overall impact on pregnancy outcome.
Food insecurity (FI) in the higher education setting is a pressing social justice and public health nutrition issue. Persistent FI rates among students suggest that the current programmes and institutional policies are inadequate. Engaging the community in co-design practices can enhance research and decision-making, leading to more targeted advocacy and solutions. This review describes and evaluates evidence of co-design approaches and identifies strategies for addressing FI in higher education settings.
Design:
A review was conducted using the Preferred Reporting Items for Systematic Reviews and Meta-Analyses extension for Scoping Reviews. Literature was searched in three electronic databases (Scopus, Ovid MEDLINE and Web of Science) and two search engines (Google and Google Scholar).
Setting:
Only studies based in higher education settings were included.
Participants:
Higher education students.
Results:
The search identified 814 studies, of which twenty-eight met the inclusion criteria. Studies involving co-design and participatory research frameworks had higher participation, leading to increased student awareness of FI, student leadership and the development of campaigns and collaborative organisational structures. A content analysis approach identified seven categories for strategies targeting student FI: (1) policy and institutional support; (2) strategic partnerships (3) advocacy and awareness; (4) initiatives for student engagement; (5) student skills and knowledge development; (6) programme development and (7) campus food environment.
Conclusions:
Co-designed research methodologies are important for addressing student FI, enhancing advocacy and understanding stakeholder needs. Future studies should prioritise collaborative approaches when exploring solutions to FI and similar social justice issues affecting students.
This paper evaluates the UK Government’s decision to increase the main form of social security by £20 per week during the coronavirus disease 2019 (COVID-19) pandemic, exploring whether increasing the generosity of social security for some, but not all, claimants affected food insecurity. Using the Family Resources Survey, we found a decline of about 7 percentage points in food insecurity amongst benefit claimants affected by the uplift compared with claimants not affected (95% CI −13.9 to −0.9%). This association did not change substantively following adjustment for covariates, nor when the model was re-estimated using matching methods. Results were not driven by changes in the composition of claimants over time. These analyses suggest food insecurity could be reduced if the generosity of the social security system increased. In actuality, the UK government went in the opposite direction, removing the £20 uplift in October 2021, potentially exposing claimants to higher rates of food insecurity again.
Supplemental Nutrition Assistance Program (SNAP) makes an exception to its rules, which allows elderly and/or disabled individuals, their spouses, as well as homeless beneficiaries, to buy hot prepared food from restaurants if they live in a state that participates in the Restaurant Meals Program (RMP). Using the staggered countywide adoption timeline in California, coupled with a stacked difference-in-differences empirical strategy, I examine the intent-to-treat (ITT) nutritional effects of RMP on the elderly population. Overall, I find no evidence that obesity rates for the elderly are any different in counties with RMP versus those without RMP. I can statistically rule out moderate effects. Additional evidence from some of the early-adopting counties suggests that RMP is associated with a reduction in food insecurity among the elderly.
The UK has experienced alarming increases in the number of individuals living with food insecurity as a result of the rise in the cost of living. The mechanisms linking household economic insecurity to food insecurity, and perceived health outcomes, are not well understood. The aim of this study was to explore how individuals with lived experience of food insecurity are coping with the rise in the cost of living, the trade-offs they might be making between food and other household expenses, and how these might impact eating behaviours and health outcomes. Using a qualitative inductive approach rooted in hermeneutic phenomenology, nine semi-structured interviews were conducted among individuals using charity-run food provision services in Bristol, UK. Narrative accounts from these interviews were analysed thematically. Almost all participants were recipients of benefits at the time of interviews and were living under high levels of economic insecurity. The rise in the cost of living forced complex budget management strategies, including relying on donated food and shoplifting. It also influenced eating behaviours through altered cooking strategies to save energy, substituting food for cheaper, less-nutritious, alternatives, and rationing meals. Food insecurity was experienced as a form of psychosocial violence, engendering high levels of stress, particularly for individuals with diet-related chronic diseases. There is therefore an urgent need for policies that tackle structural causes of overall household economic insecurity, and improve economic access to adequate nutritious foods, to prevent further entrenching social inequalities.
Food insecurity (also known as food poverty) is the inability to afford or access a healthy diet. It has become recognised as a public health emergency and is a priority in the context of the environmental, geopolitical and socio-economic implications on businesses, households and civic society. This review paper aims to discuss the merits of collecting food insecurity data and its importance in informing cross-sectoral government and others’ understanding, policymaking and action on hunger. The review paper’s key findings are that concerted action on measuring and mapping food insecurity with the aim of eliminating or reducing its prevalence represents a triple win for government, business and citizens. However, measurement does not provide solutions to food insecurity but contributes importantly to understanding its extent and severity to inform and evaluate proffered solutions. Government, business and food insecurity researchers and commentators cannot merely continue to simply describe food poverty - but must effect meaningful change amidst our communities to improve life quality in a timely way for those experiencing acute and chronic hunger. This is best done by addressing the structural causes of food insecurity through economically, socially and culturally fair and appropriate policy levers, requiring cross-sectoral collaboration. Ultimately, food insecurity requires a long-term, sustainable solution that addresses the policy issues under focus: low income, under/unemployment, rising food prices and Welfare Reform, informed by routine, Government-supported monitoring and reporting of the extent of food poverty among our citizens.
Explore the relationship between water insecurity (WI) and food security and their covariates in Mexican households.
Design:
A cross-sectional study with nationally representative data from the National Health and Nutrition Survey-Continuous 2021 (in Spanish, ENSANUT-Continua 2021), collected data from 12 619 households.
Setting:
WI was measured using the Household Water Insecurity Experiences (HWISE) Scale in Spanish and adapted to the Mexican context. Food security was measured using the Latin American and Caribbean Food Security Scale. A generalised path model was used to produce two simultaneous logistical regression equations – WI (HWISE ≥ 12) and moderate-to-severe food insecurity (FI) – to understand key covariates as well as the contribution of WI to FI.
Participants:
The head of the household, an adult of >18 years of age, consented to participate in the survey.
Results:
Households experiencing WI were more likely to experience moderate-to-severe FI (OR = 2·35; 95 % CI: 2·02, 2·72). The odds of WI were lower in households with medium (OR = 0·74; 95 % CI: 0·61, 0·9) to high (OR = 0·45; 95 % CI: 0·37, 0·55) asset scores. WI also depended on the region of Mexico. FI is more prevalent in indigenous people (OR = 1·29; 95 % CI: 1·05, 1·59) and rural households (OR = 0·42; 95 % CI: 1·16, 1·73). Notably, wealth and household size did not contribute directly to FI but did so indirectly through the mediating factor of WI.
Conclusions:
Our study shows that there are structural factors that form part of the varied determinants of WI, which in turn is closely linked to FI.
Food insecurity remains a global issue, particularly in developing countries like Ethiopia. Thus, this study focused on identifying factors contributing to food insecurity and the strategies used to cope with it among agrarian and pastoralist communities of South Ari and Benatsemay Woreda, respectively. A facility-based qualitative study was carried out in Southern Ethiopia. Participants were selected using a purposefully targeting health extension workers, health centre directors, woreda programme experts, district health managers, and pregnant women staying in maternity waiting homes. The selection process included one health facility from each district, focusing on those with the highest number of pregnant women in maternity waiting homes. A total of 17 participants were involved in in-depth interviews, and 2 focus group discussions were conducted with 27 pregnant women, continuing until data saturation was achieved. Field notes were taken, and sessions were voice recorded. Participants in both in-depth interviews and focus group discussions frequently identified several causes of food insecurity in the community, such as food shortages, climate change, rising prices of agricultural products, inadequate agricultural technology, scarcity of farmland, and income constraints. Tailored intervention is highly demanding to implement policies to stabilise food supply chains and mitigate food shortages in both agrarian and pastoralist areas, invest in modern agricultural technologies to boost productivity, encourage the adoption of climate-smart agricultural practices to help farmers adapt to changing weather patterns, optimise the productive use of available farmland, promote income-generating activities, and diversify livelihoods to alleviate income constraints and improve food security.
Free school meals (FSM) are a crucial form of support for families. This study aimed to investigate whether the FSM allowance can provide what is perceived to be, healthy, sustainable and satisfying food.
Design:
A mixed methods study incorporating co-production, citizen science and participatory approaches was conducted. Citizen scientists were given a daily budget equivalent to the FSM allowance and asked to purchase a ‘tasty, healthy and sustainable’ school lunch for a week. Alongside keeping records of available and purchased foods, young people engaged in focus groups to capture information on perceptions of food offered and FSM allowance adequacy.
Setting:
Secondary schools in Yorkshire, UK.
Participants:
Citizen scientists (n 42) aged 11–15 years across seven schools.
Results:
Obstacles were faced in obtaining sustainable and healthful meals when restricted to an FSM allowance. Reasons included restrictions in what could be purchased due to costs, limitations in the use of allowances that restricted breaktime purchases leading to hunger, inadequate portion sizes, systemic barriers like hurried lunch breaks that encourage ‘grab and go’ options and broken water fountains that led students to purchase bottled drinks. Findings were reinforced by descriptive food record data.
Conclusions:
Our findings suggest that schools would benefit from national policies to address the lack of funding, infrastructure issues and capacity to support optimal provision of food to those on FSM as well as provide greater flexibility in how pupils use their allowance. Young people verified these findings, which they presented to policymakers at a parliamentary event.
