Background/Objectives: Addressing the global syndemic of obesity, undernutrition, and climate change requires a shift toward healthy and sustainable diets. This study examines the feasibility and cost implications of implementing a Healthy and Sustainable Basic Food Basket in Chile that aligns with the EAT–Lancet diet recommendations, through its comparison with the current Basic Food Basket used for the poverty line definition. Methods: The Healthy and Sustainable Basic Food Basket was constructed based on the EAT–Lancet dietary model and was uniquely adapted to reflect the observed consumption patterns of Chile’s lowest income quintile, allowing for a more realistic affordability assessment for vulnerable populations. Food prices from the National Institute of Statistics were analyzed over a 10-year period (2014–2023). Results: This study found that the Healthy and Sustainable Basic Food Basket provides 2001 kcal per day with a balanced macronutrient distribution. However, its average cost was 13.9% higher than the Basic Food Basket, posing a significant economic barrier for low-income populations. The cost gap varied seasonally, peaking in October (21.1% higher) and narrowing in December (4.6% higher). Long-term trends showed increasing costs for both baskets, with the Healthy and Sustainable Basic Food Basket reaching its highest price in 2023, further limiting affordability. Conclusions: These findings highlight the limitations of current poverty measurement frameworks in Chile, which prioritize caloric sufficiency over nutritional quality and sustainability. This suggests a need for policy revisions to incorporate the cost of healthy and sustainable diets into poverty assessments and social protection programs. Key policy recommendations include promoting healthier diets and improved food nutrition, supporting low-carbon foods, regulating local food production and supply systems, and encouraging seasonal, local consumption. This study underscores the need for structural interventions to ensure equitable access to sustainable diets, addressing both public health and environmental concerns. Full article

Background: This project focuses on the relevance of using a health literacy approach to educating children about obesity prevention. The Habits of Health and Habits of Mind© model was used to write Electronic Texts for Health Literacy© to encourage actions that support obesity prevention. Guided by the Integrative Theory of Behavioral Prediction, the design template for a new genre of digital texts called Electronic Texts for Health Literacy© emerges for exploring children’s frame of mind, health literacy skills, and behavioral intentions toward obesity prevention. Methods: Online materials from selected websites were strategically reviewed for improving obesity prevention and child health literacy. The digital resources were juxtaposed with the Electronic Texts for Health Literacy©, with the latter written by and for children. Discussion: Health educators who use a constructivist pedagogy can help students to write health literacy narratives about obesity prevention, then read and talk about their multimodal compositions to further the practice and development of their health literacy skills. Children with obesogenic body frames can also gain from cowriting visual–textual–gestural health narratives with their peers or health professionals. Co-constructed narratives can help children make deeper connections about their identity, frame of mind, and social agency. Summary: Although this untested resource is available as a new genre of digital text, health educators could nudge children toward developing a stronger frame of mind and behavioral intentions toward obesity prevention when they write health literacy narratives that focus on decision making, goal setting, and communication in the context of eating nutritious foods and participating in physical activities.

Obesity, a complex social issue with profound health implications, intersects with various facets of society, from cultural norms to economic structures. This paper explores the sociology of obesity through multiple lenses, examining its social construction, the evaluation of societal perceptions, and the stigmatisation of obese individuals. It scrutinises the medicalisation of obesity and its consequences, urging caution in policy interventions and the interpretation of scientific evidence. Furthermore, it advocates for a nuanced approach to obesity prevention, emphasising the importance of public health policies grounded in evidence-based practices and a shared responsibility across diverse sectors. By delving into the intricate interplay between science, society. and culture, this research underscores the legitimate conditions of public health actions in fighting against the development of the obesity epidemic.

Childhood obesity is a major medical and public health issue of global interest, which is influenced by a diverse array of factors and carries significant medical and psychosocial implications. Despite the extensive studies that have been conducted to explore the specific issue, the impact of several factors that influence, generate, worsen, and make chronic the phenomenon needs further exploration. This study aimed to construct a grounded theory that includes and connects the psychological, social, parental, and biological factors affecting childhood obesity. Key psychological factors include mental health issues such as depression and emotional eating, while social factors encompass socioeconomic status and cultural influences. Parental factors involve parenting styles and feeding practices, and biological factors relate to genetic predispositions and prenatal conditions. These factors interact in complex ways, highlighting the multifactorial nature of childhood obesity. The study employed a qualitative grounded theory approach, using research articles to achieve a thorough understanding. Qualitative analysis of the articles was conducted using Atlas.ti 24.0 software. Twenty-five research articles were required to reach theoretical saturation. The analysis resulted in 336 codes that were grouped into seven broad categories and twenty-four different subcategories. Through the construction of the theoretical framework, it was recognized that obesity in minors is a complex and multifactorial issue and that the network of causes and influencing factors covers a broad spectrum ranging from the individual to the family, and subsequently to society at large, which interact with each other.

Obesity interventions typically involve some form of dietary restraint (i.e., intentional limiting of food intake), yet the restraint model of binge eating proposes that engaging in dietary restraint is a causal factor for binge eating symptoms. Evidence for this model has been mixed and differs by measures, study design, and sample. Further, there also may be moderators of the association between dietary restraint and binge eating. The purpose of this systematic review was to compile the current evidence on moderators of the association between dietary restraint and binge eating. A literature search was conducted across electronic databases, resulting in the inclusion of 16 papers (with 15 different samples). The reviewed studies were primarily heterosexual White college student females and were primarily cross-sectional studies with self-report measures. There were no consistent moderators across the studies. However, there was some evidence for interactions between affective constructs and dietary restraint in relation to binge eating, as well as three-way interactions between affect, cognitive constructs, and dietary restraint. Although there were few studies, there was little current evidence for social, biological, and demographic factors as moderators. Overall, our systematic review shows a need for further research to clarify and validate the moderators, and to understand the complex interactions as well as the potential causal relationships between restraint and binge eating behaviors.

Food and/or housing instability (FHI) has been minimally examined in post-9/11 US veterans. A randomly selected nationally representative sample of men and women veterans (n = 38,633) from the post-9/11 US veteran population were mailed invitation letters to complete a survey on health and well-being. Principal component analysis and multivariable logistic regression were used to identify FHI’s key constructs and correlates for 15,166 men and women respondents (9524 men, 5642 women). One-third of veterans reported FHI; it was significantly more likely among women than men (crude odds ratio = 1.31, 95% CI:1.21–1.41) and most prevalent post-service (64.2%). “Mental Health/Stress/Trauma”, “Physical Health”, and “Substance Use” were FHI’s major constructs. In both sexes, significant adjusted associations (p < 0.01) were found between FHI and homelessness, depression, adverse childhood experiences, low social support, being enlisted, being non-deployed, living with seriously ill/disabled person(s), and living in dangerous neighborhoods. In men only, posttraumatic stress disorder (adjusted odds ratio (AOR) = 1.37, 95% CI:1.14–1.64), cholesterol level (elevated versus normal, AOR = 0.79, 95% CI:0.67–0.92), hypertension (AOR = 1.25, 95% CI:1.07–1.47), and illegal/street drug use (AOR = 1.28, 95% CI:1.10–1.49) were significant (p < 0.01). In women only, morbid obesity (AOR = 1.90, 95%CI:1.05–3.42) and diabetes (AOR = 1.53, 95% CI:1.06–2.20) were significant (p < 0.05). Interventions are needed that jointly target adverse food and housing, especially for post-9/11 veteran women and enlisted personnel. Full article

People with overweight and obesity tend to both underreport dietary energy intake and experience weight stigma. This exploratory pilot study aimed to determine the relationship between weight bias and weight stigma and energy intake reporting accuracy. Thirty-nine weight-stable adults with BMI ≥ 25 completed three 24 h dietary recalls; indirect calorimetry to measure resting metabolic rate; a survey measuring weight stigma, psychosocial constructs, and physical activity; and a semi-structured qualitative interview. Multiple linear regression was used to determine if weight bias internalization, weight bias toward others, and experiences of weight stigma were predictive of the accuracy of energy reporting. A thematic analysis was conducted for the qualitative interviews. Weight stigma was reported by 64.1% of the sample. Weight stigma constructs did not predict the accuracy of energy intake reporting. People with obesity underreported by a mean of 477 kcals (p = 0.02). People classified as overweight overreported by a mean of 144 kcals, but this was not significant (p = 0.18). Participants reported a desire to report accurate data despite concerns about reporting socially undesirable foods. Future research should quantify the impact of weight stigma on energy reporting in 24 h recalls using a larger, more diverse sample size and objective measures like doubly labeled water for validation.

There are limited efforts to incorporate different predisposing factors into prediction models that account for population racial/ethnic composition in exploring the burden of high COVID-19 Severe Health Risk Index (COVID-19 SHRI) scores. This index quantifies the risk of severe COVID-19 symptoms among a county’s population depending on the presence of some chronic conditions. These conditions, as identified by the Centers for Disease Control and Prevention (CDC), include Chronic Obstructive Pulmonary Disease (COPD), heart disease, high blood pressure, diabetes, and obesity. Therefore, the objectives of this study were (1) to investigate potential population risk factors preceding the COVID-19 pandemic that are associated with the COVID-19 SHRI utilizing non-spatial regression models and (2) to evaluate the performance of spatial regression models in comparison to non-spatial regression models. The study used county-level data for 3107 United States counties, utilizing publicly available datasets. Analyses were carried out by constructing spatial and non-spatial regression models. Majority White and majority Hispanic counties showed lower COVID-19 SHRI scores when compared to majority Black counties. Counties with an older population, low income, high smoking, high reported insufficient sleep, and a high percentage of preventable hospitalizations had higher COVID-19 SHRI scores. Counties with better health access and internet coverage had lower COVID-19 SHRI scores. This study helped to identify the county-level characteristics of risk populations to help guide resource allocation efforts. Also, the study showed that the spatial regression models outperformed the non-spatial regression models. Racial/ethnic inequalities were associated with disparities in the burden of high COVID-19 SHRI scores. Therefore, addressing these factors is essential to decrease inequalities in health outcomes. This work provides the baseline typology to further explore many social, health, economic, and political factors that contribute to different health outcomes. Full article

The objective of this study was to evaluate the social network, food patterns, physical activity, and their associations with overweight/obesity in adolescents from a school in rural Brazil. Students from a rural school in Northeast Brazil (n = 90) completed questionnaires on sociodemographic characteristics, food consumption, physical activity, and a name generator. Social networks were constructed using students’ social proximity ties. Principal component analysis was performed to determine food patterns, and logistic models were used to investigate variables associated with overweight/obesity. Most participants were girls (62.9%), and the proportion of overweight/obesity was 30% among adolescents. Students cited 2070 people from their networks (family, friends at school, friends outside of school, and others). Among them, the family had the highest degree of influence (61%) in the network and had the most shared meals with adolescents (47%). Adolescents’ perception of their family members’ body size as obese, compared to normal or underweight, was prevalent (51%). Adolescents with unhealthy food patterns were 72% more likely to be categorized as overweight/obese, and eigenvector centrality was also associated with overweight/obesity (OR = 5.88, 95% CI = 1.08–32.03). Adolescents presented a social network with strong family influence, in which a high percentage of overweight/obesity was observed. Adolescents with high eigenvector centrality were more likely to be in the overweight/obesity category. Additionally, overweight/obesity was associated with unhealthy food patterns in the family network. Full article

Background: This study aimed to investigate the changes in distinct types of screen time and explore their longitudinal association with children and adolescents’ weight status. Methods: A two-wave longitudinal study was conducted among 2228 children and adolescents (6–19 years) in Shanghai, China, before and during the pandemic. Recreational screen time (watching TV/videos, online gaming, using social media, and browsing webpages), educational screen time (online homework and online class), and BMI were measured using a self-reported questionnaire. Mixed-effects models were constructed to assess the associations between screen time and weight status. Results: The prevalence of overweight and obesity was 20.5% and 10.2% at baseline, respectively. Both recreational and educational screen time increased significantly over two months. While recreational screen time was found to be a risk factor for obesity, it was not the case for educational screen use. Specifically, adolescents who spent more time watching TV/videos had a higher obesity risk (OR = 1.576). No significant associations were found in children. Conclusions: Overweight and obesity were prevalent among children and adolescents in China. Reducing screen-based activities is a promising strategy to prevent unhealthy weight gain in Chinese children and adolescents, while it is necessary to consider the content and distinguish between educational and recreational screen use.

Obesity is a major risk factor for cardiovascular, cerebrovascular, metabolic, and respiratory diseases, and it has become an important social health problem affecting the health of the population. Obesity is affected by both genetic and environmental factors. In this study, we constructed a diet-induced obese C57BL/6J mouse model and performed deep RNA sequencing (RNA-seq) on liner-depleted RNA extracted from the liver tissues of the mice to explore the underlying mechanisms of obesity. A total of 7469 circular RNAs (circRNAs) were detected, and 21 were differentially expressed (DE) in the high-fat diet (HFD) and low-fat diet (LFD) groups. We then constructed a comprehensive circRNA-associated competing endogenous RNA (ceRNA) network. Bioinformatic analysis indicated that DE circRNAs associated with lipid metabolic-related pathways may act as miRNA sponges to modulate target gene expression. CircRNA1709 and circRNA4842 may serve as new candidates to regulate the expression of PTEN. This study provides systematic circRNA-associated ceRNA profiling in HFD mouse liver, and the results can aid early diagnosis and the selection of treatment targets for obesity in the future.

The potential of urban parks to enhance social welfare and deliver health benefits has been recognized. However, it is still unclear which landscape characteristics in urban green spaces best improve the physical activity levels of users. Little is known about the relationship between the microenvironment of urban green spaces and the physical activity of children, particularly in the context of high levels of childhood obesity. Using the self-report method, we extracted the perceived environmental characteristics of the landscape and combined this with behavior observation to obtain the level of children’s physical activity in green spaces and to explore the influence of the characteristics of green spaces on these activities. Our results show that the highest levels of activity were found in the semiopen spaces of urban parks, which mainly consist of dense vegetation and a diverse range of recreation facilities. Play facilities were most closely related to the level of intensity of children’s activities, and perceived safety was the primary social perception factor affecting their activities. In addition, perceptions of the social environment were found to play a significant intermediary role in the impact of green space on children’s physical activity. The study results are intended to promote green space planning and design updates, improve the public health level of children, and provide a basis for the construction of child-friendly cities.

This paper aims to discuss the implications of body talk and socio-cultural pressure for the internalisation of a thin body image in purchase decisions, shopping habits and other outcomes of body dissatisfaction, in particular the proneness to avoid human/social interaction in retail contexts and proneness to engage in corrective, compensatory or compulsive shopping behaviour. This paper conducted an online questionnaire that measured the following constructs: body mass index; Socio-cultural Attitudes Towards Appearance Scale-4 (SATAQ-4), Body Appreciation Scale (BAS-2), Acceptance of Cosmetic Surgery Scale (ACSS), Compulsive Buying Follow-up Scale (CBFS), proneness to avoid social interaction in retail contexts, and the intention to purchase a list of products and services as a compensation for body dissatisfaction. A structural equations model supported the hypotheses proposing the influence of BAS-2 and SATAQ-4 (the internalisation of thin/athletic body and the social comparison induced by family, peers and media) upon the outcomes of social-interaction avoidance, ACSS and CBFS. Nevertheless, BAS-2 only influences social-interaction avoidance. This paper provides several recommendations to brand managers highlighting the social responsibility role of brand advertising in enhancing positive body appreciation, mitigating the psychological damage caused by socio-cultural pressure and preventing the stigmatisation bias against obese people.

Anxiety is one of the psychological factors associated with body weight experienced by people attempting to live up to expectations of an ideal body shape. The stigma of excessive or too low body weight and the stigmatization of people because of it is becoming a widespread problem with negative psychological and social consequences. One effect of the strong social pressure of beauty standards dependent on low body weight is the development of eating disorders and negative societal attitudes toward overweight or obese people. Research conducted to date has mainly focused on one dimension of weight-related anxiety—the fear of getting fat. Ongoing research has also revealed the other side of weight-related anxiety—fear of weight loss. Therefore, the purpose of the present project was to develop a two-dimensional scale to diagnose the level of weight-related anxiety and to preliminarily test the psychometric properties of the emerging constructs. Results: the BMAS-20 weight-related anxiety scale in both Polish and English versions was developed and its psychometric properties were confirmed. The components of body weight-change anxiety that emerged were: anxiety about getting fat and anxiety about losing weight. It was found that both AGF and ALW may have a protective function related to awareness of the negative consequences of poor eating and the health risks associated with it. Above-normal levels of anxiety may be a predictor of psychopathology. Both AGF and ALW are associated with symptoms of depression. Full article

With advances in medical diagnostic technology, the healthy development of children with autism spectrum disorder (ASD) is receiving more and more attention. In this article, the mediating effect of brain gray matter volume (GMV) between overweight/obesity and social communication (SC) was investigated through the analysis of the relationship between overweight/obesity and SC in autism spectrum disorder children. In total, 101 children with ASD aged 3–12 years were recruited from three special educational centers (Yangzhou, China). Overweight/obesity in children with ASD was indicated by their body mass index (BMI); the Social Responsiveness Scale, Second Edition (SRS-2) was used to assess their social interaction ability, and structural Magnetic Resonance Imaging (sMRI) was used to measure GMV. A mediation model was constructed using the Process plug-in to analyze the mediating effect of GMV between overweight/obesity and SC in children with ASD. The results revealed that: overweight/obesity positively correlated with SRS-2 total points (p = 0.01); gray matter volume in the left dorsolateral superior frontal gyrus (Frontal_Sup_L GMV) negatively correlated with SRS-2 total points (p = 0.001); and overweight/obesity negatively correlated with Frontal_Sup_L GMV (p = 0.001). The Frontal_Sup_L GMV played a partial mediating role in the relationship between overweight/obesity and SC, accounting for 36.6% of total effect values. These findings indicate the significant positive correlation between overweight/obesity and SC; GMV in the left dorsolateral superior frontal gyrus plays a mediating role in the relationship between overweight/obesity and SC. The study may provide new evidence toward comprehensively revealing the overweight/obesity and SC relationship. Full article
