From Streets to Tables: Bottom–Up Co-creation Case Studies for Healthier Food Environments in Vietnam and Nigeria

Current food systems fail to provide equity, sustainability, and positive health outcomes, thus underscoring the critical need for their transformation. Intervening in food environments holds substantial promise for contributing to this much-needed transformation. Despite scholars and practitioners often recognizing the necessity for bottom–up approaches, there is a dearth of empirical investigations evaluating the potential of these approaches to contribute to food system transformations in low- and middle-income countries (LMICs). Our study aimed to address this research gap, providing a unique perspective in this regard. Drawing on evidence from two co-creation case studies conducted with small-scale informal fruit and vegetable vendors and poor consumers in Vietnam and Nigeria from January 2020 to December 2021, we explored the relevance of bottom–up community-engaged co-creation processes in intervening within LMICs’ food retail environments. Employing a mixed-methods approach that includes quantitative surveys, qualitative interviews, participatory workshops, and focus group discussions, we demonstrated that bottom–up co-creation processes involving marginalized socioeconomic groups can generate retail-level innovations that are tailored to informal retail contexts, whereas remaining aligned with established top–down theories and literature pertaining to food environments and healthy diets. We provided empirical evidence highlighting how both vendors and consumers respond positively to the co-created innovations. Expanding upon our results, we offered methodological insights applicable to interventions targeted at food environments in LMICs, and considerations for future research or development initiatives in this domain. Our findings revealed the capacity of vulnerable stakeholders to actively engage in public health initiatives and contribute to developing innovative solutions that are context-specific and conducive to the adoption of healthier dietary practices. These results confirm the potential of bottom–up, co-creation, real-world interventions within informal settings to contribute toward fostering inclusive transformation of food systems.

Associations of neighborhood social cohesion and changes in BMI-The Maastricht Study.

The role of the social environment can facilitate positive health outcomes through active community engagement, normalization of healthy behaviors, and stress buffering. We aim to examine the associations of neighborhood social cohesion with changes in BMI over time. A total of 7641 participants from The Maastricht Study between the ages of 40 and 75 years were analyzed. Weight and height were measured at baseline, and weight was self-reported annually up to 10 years of follow-up (median = 4.7 years). Perceived social cohesion was obtained by questionnaire. Home addresses for each participant were linked to geographic information system data from the Geoscience and Health Cohort Consortium to create neighborhood exposure variables including area level social cohesion, neighborhood walkability, and food environment within a 1000 m Euclidian buffer. Linear regression analyses were performed with BMI adjusted for socioeconomic variables. A mixed model analysis was carried out to examine changes in BMI. Living in the highest quartile area of individually perceived social cohesion was associated with lower BMI (Q4 B: -.53; 95% CI = -.79, -.28) compared to the lowest quartile. Similar findings were discovered using the area level measure (Q4 B: -.97; 95% CI = -1.29, -.65). There was no longitudinal association between social cohesion and BMI. Neighborhood social cohesion was associated with lower BMI classifying it as an obesogenic area characteristic that influences weight, independent of conventional built environment features.

Transforming food environments: a global lens on challenges and opportunities for achieving healthy and sustainable diets for all

Cross-sectional study examining the association between diet quality and the prevalence of anxiety and depression in UK undergraduate students.

The prevalence of mental health issues among UK undergraduate students is growing, and poor diet quality appears to be a risk factor for poor mental health although with limited research in this area. Therefore, the objective of this study was to examine the cross-sectional associations between diet quality and common mental disorders (CMD) such as depression and anxiety in UK undergraduate students. A cross-sectional survey consisting of demographic information and validated questionnaires (the Short-Form Food Frequency Questionnaire [SFFFQ] and the Hospital Anxiety and Depression Scale [HADS]) was conducted to measure diet quality and anxiety and depression in young adults in 44 UK-based universities. Multiple regression analysis adjusting for confounding factors was used to assess the associations between them. Undergraduate university students (n = 202, 67% female) with a mean age of 20.9 ± 3.6 years and a mean body mass index (n = 170) of 22.6 ± 3.2 kg/m2 took part in the study. Prevalence of anxiety was high, with 40% of the sample having an anxiety score in the severe range (≥12 points) while the prevalence of depression was lower, with 6% of the population having a depression score in the severe range (≥12 points). Diet quality was significantly higher for females than males (p = 0.034) and was poor for 38% of the sample, being more common in males compared to females, although not significantly so (43% and 36%, respectively). Diet quality was inversely associated with anxiety (β = -0.427; p = 0.029) and was more likely to be associated with anxiety in females than males (β = 0.743; p = 0.043). No significant relationship between diet quality and depression was found. Better self-reported health, father's qualification and smoking status were also associated with less anxiety and depression. This research supports other research suggesting that UK universities should explore whether the implementation of dietary interventions and improving the food environment would be a cost-effective option to reduce the high prevalence of anxiety among students.

Dietary Quality and Diet-Related Factors Among Emerging Adults (18–23 y) in the United States Are a Cause for Concern: National Health and Nutrition Examination Survey 2015–2018

BackgroundPoor dietary quality is a risk factor for diet-related chronic disease and suboptimal nutritional patterns often begin early in the life course. Although the dietary intakes of young children, adolescents, and middle-aged and older adults are well established, much less is known about emerging adults, who represent a unique time point in life, as they are undergoing significant changes in food environments, autonomy, finances, and caregiver and parental involvement. ObjectivesThis study aimed to examine dietary quality, as assessed via the Healthy Eating Index (HEI), by demographic, socioeconomic, and health-related characteristics among emerging adults (18–23 y) in the United States who participated in the 2015–2018 National Health and Nutrition Examination Survey (NHANES). MethodsNHANES data were collected via a household interview and 2 24-h dietary recalls (24HR). Usual dietary intakes from the 24HRs were approximated using the multivariate National Cancer Institute Method to compute mean HEI-2015 overall and component scores (range: 0–100; higher scores indicating higher dietary quality). ResultsOverall dietary quality among emerging adults (HEI-2015: 50.3 ± 1.3) was significantly lower than other adults (≥24 y) (HEI-2015: 56.3 ± 0.5; P < 0.0001) in the United States, with differences primarily driven by lower intakes of whole fruit, vegetables, and whole grains and higher intakes of sodium, refined grains, and saturated fat. Few differences in HEI-2015 scores were noted across population subgroups by sex, food security, family income, and food assistance program participation, except for added sugar; intakes of added sugar were significantly higher among women, food insecure, and food assistance program participants than those in their counterparts, respectively. ConclusionsDietary quality is poor among emerging adults in the United States and persists across all population subgroups, suggesting a significant need for tailored public health interventions to improve dietary quality among this population. Future research investigating to what extent emerging adults prioritize healthful behaviors and exploring other indicators for identifying nutritionally vulnerable subgroups may be impactful for identifying disparities among this life stage.

Influence of Food Environments on Dietary Habits: Insights from a Quasi-Experimental Research.

Nutrition is a vital factor that exerts a profound and direct impact on health. Food environments significantly influence individuals' dietary behaviors, health outcomes, and overall food security. Individuals in food deserts and food swamps do not have access to healthier food options. And in both cases, the emphasis is primarily on the physical configuration of the environment as it relates to food availability. This quasi-experimental study aims to investigate the impact of two different food environments (defined to include a social component) on food choices. A total of 246 participants were surveyed by telephone, half of whom were primed with Scenario A (a food environment deficient in healthy options and cues that support and reinforce healthier choices) and half were primed with Scenario B (an environment with an abundance of healthy food options and cues that support and reinforce healthy eating). Ordered logit regression was used for analysis. The results show significant differences in likely food consumption between the groups. Individuals in Scenario B were found to be 4.48 times more likely to consume fruits and vegetables. In addition, it was determined that being a woman increases the probability of consuming more fruits and vegetables by 0.92 times (1/0.52-1), and adherence to a healthy diet increases by 3.64 times. Age and race were not significant predictors. This study highlights the crucial role of environmental factors in shaping dietary habits and underscores the importance of the social components of the food environment in promoting the adoption of healthier dietary habits. Based on these findings, policymakers should prioritize developing strategies that go beyond providing physical access and consider social aspects of the environment in promoting healthy eating habits to improve public health and bolster the food security of communities.

SFDRS as a metalanguage for ‘foodscaping’: adding a formal dimension to an interdisciplinary, multimodal approach to food

‘Foodscaping’ seeks to understand how meaning is made through humans’ interaction with food in particular environments through a multimodal and interdisciplinary analytical lens. As part of a foodscaping project, researchers often interpret food environments to which they are not intimately ‘local’. This presents cross-cultural limitations in the production of analysis. Most pertinently, how can personal interpretation be divorced from locally salient and meaningful discourses? This paper presents the findings of a pilot foodscaping analysis using the box notation style of Kim’s Korean Segmented Film Discourse Representation Structures (K-SFDRS). K-SFDRS notation, developed to provide both coarser- and finer-grained formal transcription for South Korean multimodal film discourse analysis, is tested as an analytic tool for an authentic South Korean foodscaping experience. This paper aims to ascertain whether the formal nature of K-SFDRS transcription is a useful aid to the analysis of a foodscape, which otherwise risks relying heavily on personal interpretation. This pilot study presents an introduction to both foodscaping and (K-)SFDRS, outlines the potentials of (K-)SFDRS notation within a foodscaping context, offers a step-by-step outline for constructing K-SFDRS box notation using an exemplar South Korean foodscape, and finally demonstrates how this box notation may be used in the support of foodscaping analysis in various interdisciplinary channels. During this pilot study, the authors make a novel methodological development in the form of what they term ‘cluster structures’, which overcome the problems presented by the lack of cinematic narrative editing in spontaneous discourse, segmenting meaning into logical forms within which structures of meaning are hierarchised without requiring the discourse relations to structure the logical forms themselves in narrative discourse following the original K-SFDRS methodology. The paper concludes that K-SFDRS, alongside the aforementioned methodological development, has potential to help foodscaping researchers constrain interpretation to salient discourses and direct foodscaping analysis down meaningful avenues. Through its culinary scope, this chapter adds a new disciplinary dimension to discussions of metalanguage and makes an innovative contribution to the current corpus of multimodal research.

Perceived but not objective measures of neighborhood safety and food environments are associated with longitudinal changes in processing speed among urban older adults

BackgroundAlthough a growing body of literature documents the importance of neighborhood effects on late-life cognition, little is known about the relative strength of objective and subjective neighborhood measures on late-life cognitive changes. This study examined effects of objective and subjective neighborhood measures in three neighborhood domains (neighborhood safety, physical disorder, food environments) on longitudinal changes in processing speed, an early marker of cognitive aging and impairment.MethodsThe analysis sample included 306 community-dwelling older adults enrolled in the Einstein Aging Study (mean age = 77, age range = 70 to 91; female = 67.7%; non-Hispanic White: 45.1%, non-Hispanic Black: 40.9%). Objective and subjective measures of neighborhood included three neighborhood domains (i.e., neighborhood safety, physical disorder, food environments). Processing speed was assessed using a brief Symbol Match task (unit: second), administered on a smartphone device six times a day for 16 days and repeated annually for up to five years. Years from baseline was used as the within-person time index.ResultsResults from mixed effects models showed that subjective neighborhood safety (β= -0.028) and subjective availability of healthy foods (β= -0.028) were significantly associated with less cognitive slowing over time. When objective and subjective neighborhood measures were simultaneously examined, subjective availability of healthy foods remained significant (β= -0.028) after controlling for objective availability of healthy foods. Associations of objective neighborhood crime and physical disorder with processing speed seemed to be confounded by individual-level race and socioeconomic status; after controlling for these confounders, none of objective neighborhood measures showed significant associations with processing speed.ConclusionSubjective neighborhood safety and subjective availability of healthy foods, rather than objective measures, were associated with less cognitive slowing over time over a five-year period. Perception of one’s neighborhood may be a more proximal predictor of cognitive health outcomes as it may reflect one’s experiences in the environment. It would be important to improve our understanding of both objective and subjective neighborhood factors to improve cognitive health among older adults.

Enhancing Soil Health and Fertility Management for Sustainable Agriculture: A Review

In modern agriculture, ensuring soil health and effective fertility management are paramount for sustainable crop production and environmental stewardship. This review article comprehensively explores a spectrum of strategies aimed at enhancing soil health and fertility management within the context of sustainable agriculture. Beginning with an overview of the pivotal role soil health plays in agricultural systems, the review meticulously examines the significance of adopting sound soil fertility management practices to sustain soil productivity while mitigating adverse environmental impacts. Traditional and innovative approaches to soil management are thoroughly discussed, encompassing a range of practices such as organic amendments, cover cropping, crop rotation, reduced tillage, and integrated nutrient management. These practices, deeply rooted in agricultural traditions, are shown to enhance soil structure, foster nutrient cycling, and promote beneficial soil microbial communities, thereby contributing to long-term soil health and productivity. Furthermore, the review elucidates emerging technologies and methodologies that hold promise for revolutionizing soil health and fertility management in sustainable farming systems. Precision agriculture techniques leveraging GPS, remote sensing, and data analytics are highlighted for their potential to optimize resource use and improve crop management practices. Biochar application, a burgeoning area of research, is explored for its ability to enhance soil fertility, sequester carbon, and improve soil water retention. Additionally, manipulation of the soil microbiome through innovative techniques presents exciting opportunities for enhancing soil health and resilience, the review underscores the importance of continued research, education, and policy support in promoting sustainable soil management practices. Recommendations for future research directions are provided, emphasizing the need for interdisciplinary collaborations, long-term field studies, and farmer participatory research. Practical implications for farmers and policymakers are also delineated, emphasizing the imperative of adopting holistic approaches to soil management that integrate traditional wisdom with cutting-edge technologies. By embracing sustainable soil management practices, farmers and policymakers can safeguard soil health, enhance agricultural productivity, and ensure the long-term sustainability of our food systems and environment.

Strategies associated with improved healthiness of consumer purchasing in supermarket interventions: a systematic overview of reviews and evaluation of primary articles.

Growing evidence suggests that it is possible to change the retail food environment to enable healthier choices via in-store interventions. It has been difficult to draw clear conclusions as to which interventions are most effective in positively influencing consumer purchasing behaviour given the significant heterogeneity within the food retail research literature. The aim of this study was to (1) summarise current high-quality systematic, scoping, and/or narrative reviews (Part I: overview of reviews); and (2) synthesise high-quality original research, to understand the range, types and effectiveness of strategies implemented in food retail settings (Part II: evaluation of primary studies). To identify reviews describing the effects of intervention strategies aiming to improve the healthiness of consumer purchasing in supermarkets, a systematic search across seven electronic databases was completed in April 2023. The methodological quality of reviews was assessed using the risk of bias in systematic reviews for systematic and scoping reviews, and the Scale for the Assessment of Narrative Review Articles for narrative reviews. High-quality reviews were further inspected and synthesised narratively (Part I). Next, to understand strategies associated with improved healthiness of consumer purchasing high-quality, primary articles from high-quality reviews identified in Part I were retrieved, and the strategies implemented within these interventions were summarised (Part II). Thirty-eight reviews met the inclusion criteria for Part I; two-thirds (n = 25, 66%) were rated as high-quality (66%). These reviews indicated that pricing strategies had the greatest proportion of reported positive or promising effects on outcomes (n = 8 of 11 reviews, 73%). Twenty reviews met the inclusion criteria for Part II and the 771 primary articles from these reviews were screened with 23 high-quality primary articles included in analysis. Findings indicated that promotional strategies in combination with another strategy appeared to be most successful among regular shoppers (the general population), whereas pricing was most successful in low socio-economic status and rural sub-groups. Promotion, pricing and prompting were the most commonly tested strategies across the overview of reviews and review of primary articles. Promotion, in combination with other strategies, and pricing appear to be most promising, but the effectiveness of pricing strategies may vary by sub-groups of the population. How pricing and promotion in combination with other strategies can be implemented responsibly and sustainably to change purchase habits towards healthier items should be explored further.

Relationship between body mass index and residential segregation in large cities of Latin America

BackgroundObesity is a global health problem, and its connection with social and environmental factors is well-established. Social factors, such as urban segregation, may impact obesity through various mechanisms, including food and physical activity environments, as well as social norms and networks. This multilevel study aims to examine the effect of socio-economic residential segregation of Latin American cities on the obesity of individuals within those cities.MethodsWe analyzed data from national surveys for a total of 59,340 individuals of 18–70 years of age, conducted in 156 cities across Brazil, Chile, Colombia, and Mexico between 2007 and 2013. We adjusted two-level linear mixed models for body mass index (BMI) stratified by sex and country, controlling for age, educational level and poverty. Separate models were built for dissimilarity and isolation segregation indices.ResultsThe relationships between segregation indices and BMI were mostly not statistically significant, and in some cases, they were opposite to what was expected. The only significant relationships were observed in Colombian men, using the dissimilarity index (-7.5 [95% CI: -14.4, -0.5]) and in Colombian women, using the isolation index (-7.9 [95% CI: -14.1, -1.7]).ConclusionsWhile individual-level factors cannot fully explain differences among people in the same city, segregation indices may help. However, we found that in some cases, the relationship between BMI and segregation indices is opposite to what is expected based on prior literature. This should be considered in examining the phenomenon. Further research on obesogenic environments in segregated neighborhoods could provide valuable evidence.
