Association of Fast-Food and Full-Service Restaurant Densities With Mortality From Cardiovascular Disease and Stroke, and the Prevalence of Diabetes Mellitus

Spatiotemporal effects of urban micro-scale built environment on cardiovascular diseases

Cardiovascular disease (CVD) has become a significant threat to the health of urban populations, and the urban built environment, as a key determinant of cardiovascular health, affects residents through various dimensions including physical activity, urban pollution, mental health, and dietary habits. However, existing research predominantly focuses on macro-level geographic scales, with limited exploration of the potential impact of intra-urban microenvironments on CVD. This study focuses on the central area of Nanning, China, as the case study area, employing methods such as global spatial autocorrelation analysis, emerging spatiotemporal hotspot analysis, and spatiotemporal geographically weighted regression (GTWR) analysis to comprehensively examine the spatiotemporal associations between CVD and built environment elements. The results reveal that CVD and built environment elements exhibit significant spatial clustering and correlations, with all variables demonstrating spatial clustering patterns. Six built environment factors-parks and squares, transportation facilities, life services, sports and leisure, medical care, and Catering and food-are spatially associated with disease incidence. The influence of built environment factors on CVD varies and exhibits pronounced spatiotemporal heterogeneity, with the greatest coefficient fluctuation observed for parks and squares, and the smallest for catering services. Parks and squares generally contribute positively to cardiovascular health by lowering disease risk across most areas, although in the central zone, dense population and heavy traffic lead to a positive association with disease incidence. Fortunately, this adverse impact has been gradually mitigated through ongoing improvements in urban green space planning; transportation facilities increases disease risk due to associated noise and air pollution, with particularly strong effects observed in the central region. However, the implementation of green transportation initiatives has effectively mitigated this negative impact; life services show a positive association with CVD, but their diverse types and spatially balanced distribution render their impact relatively minor; sports and leisure are associated with reduced disease risk in the central part of the study area, but in the northeast and northwest, they exhibit a positive association due to population dispersion. As residents' usage habits become more consistent, the associated impacts are gradually stabilizing; medical care help reduce disease risk in the central and eastern regions, but show a positive correlation in the northern area due to patient overflow and referral patterns. With the more equitable distribution of healthcare resources, this relationship is gradually stabilizing; catering and food are positively associated with CVD, but the effect is relatively small and spatially balanced, likely due to their widespread and uniform distribution. These findings offer valuable case-based evidence for urban planning and public health policymaking, thereby contributing to the construction and advancement of healthy cities.

The association between food environments and cardiovascular disease outcomes: A systematic review

BACKGROUND

Cardiovascular disease (CVD) is the leading cause of death worldwide, particularly affecting low- and middle-income countries. Food environments may be linked with the risk of CVD; however, current study findings regarding their relationship are inconsistent. A systematic review of their associations is needed to guide interventions to improve cardiovascular health.

OBJECTIVE

This systematic review aimed to comprehensively assess the relationship between food environments and CVD outcomes, including incidence, hospitalization, mortality, and recurrence rates.

METHOD

According to PRISMA guidelines, a systematic search was conducted until 28th March 2024, using eight databases, including PubMed, Embase, Ovid, CINAHL, Web of Science, Cochrane Library, China National Knowledge Infrastructure (CNKI), and Wanfang Data. The review quality was assessed according to the Agency for Healthcare Research and Quality (AHRQ) and Newcastle-Ottawa Scale (NOS). The included studies were categorized based on their exposure factors into unhealthy, healthy, and comprehensive food environments, encompassing facilities that offer healthy and unhealthy foods. The findings were narratively synthesized according to this classification.

RESULT

A total of 23 studies, encompassing 13 cross-sectional studies and 10 cohort-longitudinal studies, were included in this review. Among the 20 studies on unhealthy food environments, 13 found a positive association with CVD outcomes. Of the seven studies on healthy food environments, 3 found a negative association with CVD outcomes. Additionally, 4 out of 8 studies on comprehensive food environments found a significant but inconsistent association with CVD outcomes.

CONCLUSION

This study suggested that unhealthy food environments are probably associated with CVD outcomes. At the same time, there is currently no conclusive evidence to indicate a relationship between healthy food environments or comprehensive food environments and CVD outcomes.

Spatial analysis of the impact of urban built environment on cardiovascular diseases: a case study in Xixiangtang, China

BACKGROUND

The built environment, as a critical factor influencing residents' cardiovascular health, has a significant potential impact on the incidence of cardiovascular diseases (CVDs).

METHODS

Taking Xixiangtang District in Nanning City, Guangxi Zhuang Autonomous Region of China as a case study, we utilized the geographic location information of CVD patients, detailed road network data, and urban points of interest (POI) data. Kernel density estimation (KDE) and spatial autocorrelation analysis were specifically employed to identify the spatial distribution patterns, spatial clustering, and spatial correlations of built environment elements and diseases. The GeoDetector method (GDM) was used to assess the impact of environmental factors on diseases, and geographically weighted regression (GWR) analysis was adopted to reveal the spatial heterogeneity effect of environmental factors on CVD risk.

RESULTS

The results indicate that the built environment elements and CVDs samples exhibit significant clustering characteristics in their spatial distribution, with a positive correlation between the distribution density of environmental elements and the incidence of CVDs (Moran's I > 0, p < 0.01). Further factor detection revealed that the distribution of healthcare facilities had the most significant impact on CVDs (q = 0.532, p < 0.01), followed by shopping and consumption (q = 0.493, p < 0.01), dining (q = 0.433, p < 0.01), and transportation facilities (q = 0.423, p < 0.01), while the impact of parks and squares (q = 0.174, p < 0.01) and road networks (q = 0.159, p < 0.01) was relatively smaller. Additionally, the interaction between different built environment elements exhibited a bi-factor enhancement effect on CVDs. In the local analysis, the spatial heterogeneity of different built environment elements on CVDs further revealed the regional differences and complexities.

CONCLUSIONS

The spatial distribution of built environment elements is significantly correlated with CVDs to varying degrees and impacts differently across regions, underscoring the importance of the built environment on cardiovascular health. When planning and improving urban environments, elements and areas that have a more significant impact on CVDs should be given priority consideration.

Child and adolescent exposure to unhealthy food marketing across digital platforms in Canada

BACKGROUND

Children and adolescents are exposed to a high volume of unhealthy food marketing across digital media. No previous Canadian data has estimated child exposure to food marketing across digital media platforms. This study aimed to compare the frequency, healthfulness and power of food marketing viewed by children and adolescents across all digital platforms in Canada.

METHODS

For this cross-sectional study, a quota sample of 100 youth aged 6-17 years old (50 children, 50 adolescents distributed equally by sex) were recruited online and in-person in Canada in 2022. Each participant completed the WHO screen capture protocol where they were recorded using their smartphone or tablet for 30-min in an online Zoom session. Research assistants identified all instances of food marketing in the captured video footage. A content analysis of each marketing instance was then completed to examine the use of marketing techniques. Nutritional data were collected on each product viewed and healthfulness was determined using Health Canada's 2018 Nutrient Profile Model. Estimated daily and yearly exposure to food marketing was calculated using self-reported device usage data.

RESULTS

51% of youth were exposed to food marketing. On average, we estimated that children are exposed to 1.96 marketing instances/child/30-min (4067 marketing instances/child/year) and adolescents are exposed to 2.56 marketing instances/adolescent/30-min (8301 marketing instances/adolescent/year). Both children and adolescents were most exposed on social media platforms (83%), followed by mobile games (13%). Both age groups were most exposed to fast food (22% of marketing instances) compared to other food categories. Nearly 90% of all marketing instances were considered less healthy according to Health Canada's proposed 2018 Nutrient Profile Model, and youth-appealing marketing techniques such as graphic effects and music were used frequently.

CONCLUSIONS

Using the WHO screen capture protocol, we were able to determine that child and adolescent exposure to the marketing of unhealthy foods across digital media platforms is likely high. Government regulation to protect these vulnerable populations from the negative effects of this marketing is warranted.

Adverse childhood experiences and unhealthy dietary behaviours in adulthood

OBJECTIVE

This study assesses the relationship between adverse childhood experiences (ACE) occurring before the age of 18 years and patterns of fast-food consumption and sugary beverage consumption in adulthood. The study also examines how perceived stress and socio-economic status (SES) (college educational attainment and income) in adulthood mediate this relationship.

DESIGN

Using data from the National Longitudinal Study of Adolescent to Adulthood Health (N 8599), multinomial logistic regression analyses were carried out to assess the association between ACE and unhealthy dietary behaviours in adulthood. Karlson-Holm-Breen mediation analysis is used to determine the mediating effects of SES and perceived stress.

SETTING

Persons living in the USA in 2016-2018.

PARTICIPANTS

Adults (n 8599) aged 33-44 years.

RESULTS

The findings show an association between four or more ACE and high fast-food (relative risk ratio (RRR) = 1·436, 95 % CI = 1·040, 1·983) and high sugary beverage consumption (RRR = 1·435, 95 % CI = 1·002, 2·055). The association between ACE and high fast-food consumption is partially mediated by college educational attainment, and the association between ACE and high sugary beverage consumption is partially mediated by perceived stress and college educational attainment.

CONCLUSIONS

ACE can have long-term consequences for unhealthy dietary behaviours in adulthood, and this relationship is partially due to a lower likelihood of higher perceived stress and college educational attainment among ACE-exposed persons. Future research is needed to understand further the influence of ACE on dietary patterns over the life course.

Associations between the neighbourhood food environment and cardiovascular disease: a systematic review

AIMS

To systematically review the current evidence on the association between the neighbourhood food environment and cardiovascular disease (CVD) in adults.

METHODS AND RESULTS

We searched the literature databases CINAHL, MEDLINE, and EMBASE for studies published between 1 January 2000 and 1 May 2022. Studies focusing on the indoor home, workplace, or school food environment were excluded. Two independent reviewers screened all records. Included studies were assessed for risk of bias using the shortened QUIPS tool, and relevant data were extracted. We summarized the findings using a narrative synthesis approach. We included 15 studies after screening 5915 original records. Most studies were published in the last 4 years and were predominantly conducted in North American or European countries. These studies focused on fast-food restaurant density in the residential neighbourhood. A higher fast-food restaurant density was most consistently associated with a higher prevalence and incidence of CVD and CVD mortality, but effect sizes were small. Evidence of an association between fast-food restaurant density and myocardial infarction, or stroke was inconsistent. The other aspects of the food environment were density of food service restaurants, unhealthy food outlets, and food access score. However, there was scant evidence for these aspects.

CONCLUSION

We found evidence for associations between the neighbourhood food environment and CVD, suggesting that a higher fast-food restaurant density is associated with CVD and CVD mortality. Effect sizes were small but important, given the fact that a large population is exposed. Research is needed to assess the effects of other aspects of the food environment.

Association Between MIND Diet Adherence and Mortality: Insights from Diabetic and Non-Diabetic Cohorts

BACKGROUND/OBJECTIVES

To date, evidence regarding the protective roles of the Mediterranean-Dietary Approaches to Stop Hypertension Intervention for Neurodegenerative Delay (MIND) diet in patients with type 2 diabetes mellitus (T2DM) is scarce. This study aims to estimate the impact of adhering to the MIND diet on the mortality in patients with and without T2DM.

SUBJECTS/METHODS

In this cohort study, 6887 participants (1021 patients with T2DM) from the NHANES dataset were analyzed. The exposure is the MIND diet adherence. The primary outcomes are all-cause and cardiovascular (CV) deaths.

RESULTS

We documented 1087 all-cause deaths consisting of 377 CV deaths during the follow-up (median time of 10 years). Among participants with T2DM, those with a high MIND score (> 8.0, range of MIND score: 4.5-13) had a significantly lower risk of all-cause death (hazard ratio [HR] 0.75, 95% confidence interval [CI]: 0.59, 0.96, P = 0.021) and CV death (HR 0.50, 95% CI: 0.29, 0.87, P = 0.014) compared to those with a low MIND score (≤ 8.0). In participants without T2DM, a high MIND score was associated with a significant decrease in the risk of all-cause death (HR = 0.83, 95% CI: 0.70, 0.99, P < 0.001), but the association with CV death risk was not statistically significant.

CONCLUSION

This study uncovered significant associations between the MIND diet and decreased risk of all-cause and CV death in patients with T2DM. The findings highlight the potential benefits of following the MIND diet in managing and enhancing the outcomes of individuals with T2DM.

Multi-omics approach to socioeconomic disparity in metabolic syndrome reveals roles of diet and microbiome

The epidemy of metabolic syndrome (MetS) is typically preceded by adoption of a "risky" lifestyle (e.g., dietary habit) among populations. Evidence shows that those with low socioeconomic status (SES) are at an increased risk for MetS. To investigate this, we recruited 123 obese subjects (body mass index [BMI] ≥ 30) from Chicago. Multi-omic data were collected to interrogate fecal microbiota, systemic markers of inflammation and immune activation, plasma metabolites, and plasma glycans. Intestinal permeability was measured using the sugar permeability testing. Our results suggest a heterogenous metabolic dysregulation among obese populations who are at risk of MetS. Systemic inflammation, linked to poor diet, intestinal microbiome dysbiosis, and gut barrier dysfunction may explain the development of MetS in these individuals. Our analysis revealed 37 key features associated with increased numbers of MetS features. These features were used to construct a composite metabolic-inflammatory (MI) score that was able to predict progression of MetS among at-risk individuals. The MI score was correlated with several markers of poor diet quality as well as lower levels of gut microbial diversity and abnormalities in several species of bacteria. This study reveals novel targets to reduce the burden of MetS and suggests access to healthy food options as a practical intervention.

Perspective: Teaching Kitchens: Conceptual Origins, Applications and Potential for Impact within Food Is Medicine Research

There is a need to identify innovative strategies whereby individuals, families, and communities can learn to access and prepare affordable and nutritious foods, in combination with evidence-based guidance about diet and lifestyle. These approaches also need to address issues of equity and sustainability. Teaching Kitchens (TKs) are being created as educational classrooms and translational research laboratories to advance such strategies. Moreover, TKs can be used as revenue-generating research sites in universities and hospitals performing sponsored research, and, potentially, as instruments of cost containment when placed in accountable care settings and self-insured companies. Thus, TKs can be considered for inclusion in future health professional training programs, and the recently published Biden-Harris Administration Strategy on Hunger, Nutrition and Health echoes this directive. Recent innovations in the ability to provide TK classes virtually suggest that their impact may be greater than originally envisioned. Although the impact of TK curricula on behaviors, outcomes and costs of health care is preliminary, it warrants the continued attention of medical and public health thought leaders involved with Food Is Medicine initiatives.

Better adherence to the MIND diet is associated with lower risk of all-cause death and cardiovascular death in patients with atherosclerotic cardiovascular disease or stroke: a cohort study from NHANES analysis

The Mediterranean-DASH intervention for neurodegenerative delay (MIND) diet has been evaluated as a brain-protective diet pattern that contributes to better cognitive performance and attenuates dementia. Cardioprotective effects of the MIND diet have been demonstrated in the primary prevention of atherosclerotic cardiovascular disease (ASCVD), however, there is no exploration in patients with ASCVD. In this prospective cohort study, 943 patients with ASCVD or stroke from the National Health and Nutrition Examination Survey (NHANES) from 2003 to 2006 were enrolled and divided into three groups according to the MIND diet scores (≤7.0, 7.5-8.0, and ≥8.5). Compared with patients with low MIND diet scores (≤7.0), patients with better adherence to the MIND diet presented a significantly lower risk of all-cause and CV death, as results showed that the hazard ratio [HR] and 95% confidence interval [CI] were 1.09 (0.78, 1.52) in the group of 7.5-8.0, 0.66 (0.50, 0.87) in the group of ≥8.5 for all-cause mortality (P trend = 0.002); 0.70 (0.42, 1.17) in the group of 7.5-8.0 and 0.52 (0.35, 0.75) in the group of ≥8.5 for CV mortality (P for trend < 0.001). Besides, per one-score increase in the MIND diet score was associated with a 10% (HR = 0.90, 95% CI: 0.82, 0.99) lower risk of all-cause mortality and a 16% (HR = 0.84, 95% CI: 0.73, 0.97) lower risk of CV mortality in these patients. In conclusion, this study, for the first time, revealed that better adherence to the MIND diet was associated with improved outcomes in patients with ASCVD.

Prevalence of Fast Food Intake among a Multi-Ethnic Population of Young Men and Its Connection with Sociodemographic Determinants and Obesity

Fast food is commonly consumed by young adults. Eating fast food is connected with the risk of obesity and other related diseases. The present study examines the prevalence of fast food intake in a diverse sample of young men. This cross-sectional study included 3600 young men (20-35 years) who resided in Riyadh, KSA. The frequency of fast food intake was assessed using a valid and reliable questionnaire. Weekly and daily intake of fast food were the two outcome variables adopted to assess the intake frequency. Weight and height were measured. Fast food was eaten by 88.8% and 50.1% of participants weekly and daily, respectively. Fast food intake was predicted by the nationality of participants. The highest prevalence of weekly fast food intake (99.7%) was observed among Saudi, Egyptian, and Indian participants, while the lowest rate was observed among Sudanese participants (48.6%). The highest and lowest rates of daily intake were seen among Filipino (83.4%) and Bangladeshi (6.3%) participants. Obesity was another predictor of fast food intake. Obese participants had a significantly higher odds ratio of weekly (OR = 2.89, p = 0.006) and daily (OR = 1.39, p = 0.021) fast food intake than non-overweight/non-obese participants. In conclusion, fast food is frequently consumed by young men in KSA. Our findings link the likelihood of fast food intake to sociodemographic determinants and obesity.

Dietary Risk Factors and Eating Behaviors in Peripheral Arterial Disease (PAD)

Dietary risk factors play a fundamental role in the prevention and progression of atherosclerosis and PAD (Peripheral Arterial Disease). The impact of nutrition, however, defined as the process of taking in food and using it for growth, metabolism and repair, remains undefined with regard to PAD. This article describes the interplay between nutrition and the development/progression of PAD. We reviewed 688 articles, including key articles, narrative and systematic reviews, meta-analyses and clinical studies. We analyzed the interaction between nutrition and PAD predictors, and subsequently created four descriptive tables to summarize the relationship between PAD, dietary risk factors and outcomes. We comprehensively reviewed the role of well-studied diets (Mediterranean, vegetarian/vegan, low-carbohydrate ketogenic and intermittent fasting diet) and prevalent eating behaviors (emotional and binge eating, night eating and sleeping disorders, anorexia, bulimia, skipping meals, home cooking and fast/ultra-processed food consumption) on the traditional risk factors of PAD. Moreover, we analyzed the interplay between PAD and nutritional status, nutrients, dietary patterns and eating habits. Dietary patterns and eating disorders affect the development and progression of PAD, as well as its disabling complications including major adverse cardiovascular events (MACE) and major adverse limb events (MALE). Nutrition and dietary risk factor modification are important targets to reduce the risk of PAD as well as the subsequent development of MACE and MALE.

Consumption of takeaway and delivery meals is associated with increased BMI and percent fat among UK Biobank participants

BACKGROUND

Consumption of meals bought from out-of-home sources is a suggested risk factor for obesity, but the supporting evidence is mixed.

OBJECTIVES

To investigate the association between consumption of different types of meals and BMI or percent body fat.

METHODS

Data were from the UK Biobank in response to a "Type of Meals Eaten" survey, which specified the sources of the meals consumed over the previous 24 h. Because direction of causality is unknown, the data were analyzed with meal choice as the dependent variable first and then BMI as the dependent variable second.

RESULTS

The total number of participants was 5197 (2841 women and 2356 men). Participants with higher BMI and percent body fat were more likely to report consuming takeaway and/or delivery meals, with prevalence ORs (95% CIs) of 2.12 (95% CI: 1.40, 3.22; Bonferroni P < 0.0001) for women's adjusted BMI, 1.95 (95% CI: 1.30, 2.93; Bonferroni P < 0.0001) for women's adjusted percent body fat, 1.65 (95% CI: 1.05, 2.59; Bonferroni P < 0.002) for men's adjusted BMI, and 1.41 (95% CI: 0.70, 2.84; Bonferroni P < 0.01) for men's adjusted percent body fat. As BMI and percent body fat increased, both men and women were increasingly less likely to report having consumed a home-cooked and prepared meal during the previous 24 h. Analyzing the data with BMI and percent body fat as the dependent variable showed that both unadjusted and adjusted BMI and percent body fat were higher in individuals reporting consumption of takeaway and delivery foods the previous day and lower in those consuming homecooked meals. The probability of having consumed a meal that was prepared and eaten at a restaurant and/or café was also associated with BMI and percent fat among men but not women.

CONCLUSIONS

Homecooked meals were more often consumed by those with low BMI and percent body fat, whereas delivery and takeaway meals were more often eaten by individuals with higher BMI. Consumption of fast-food/café meals was not consistently associated with BMI or percent body fat. The direction of causality in these associations cannot be inferred from this cross-sectional study.

Obesogenic environments and cardiovascular disease: a path analysis using US nationally representative data

INTRODUCTION

People living in obesogenic environments, with limited access to healthful food outlets and exercise facilities, generally have poor health. Previous research suggests that behavioral risk factors and indicators of physiological functioning may mediate this link; however, no studies to date have had the requisite data to investigate multi-level behavioral and physiological risk factors simultaneously. The present study conducted serial and parallel mediation analyses to examine behavioral and physiological pathways explaining the association between environmental obesogenicity and cardiovascular disease (CVD).

METHODS

This cross-sectional observational study used data from the 2012-2016 Health and Retirement Study, a representative survey of US older adults (n = 12,482, mean age 65.9). Environmental obesogenicity was operationalized as a combined score consisting of nine environmental measures of food and physical activity. CVD and health-compromising behaviors (diet, alcohol consumption, smoking, and exercise) were self-reported. Physiological dysregulation was assessed with measured blood pressure, heart rate, HbA1c, cholesterol levels, BMI, and C-reactive protein. The Hayes Process Macro was used to examine serial and parallel paths through health-compromising behaviors and physiological dysregulation in the environmental obesogenicity-CVD link.

RESULTS

People living in more obesogenic environments had greater odds of self-reported CVD (odds ratio = 1.074, 95% confidence interval (CI): 1.028, 1.122), engaged in more health-compromising behaviors (β = 0.026, 95% CI: 0.008, 0.044), and had greater physiological dysregulation (β = 0.035, 95% CI: 0.017, 0.054). Combined, health-compromising behaviors and physiological dysregulation accounted for 7% of the total effects of environmental obesogenicity on CVD.

CONCLUSION

Behavioral and physiological pathways partially explain the environmental obesogenicity-CVD association. Obesogenic environments may stymie the success of cardiovascular health-promotion programs by reducing access to resources supporting healthy lifestyles.

The ontology of fast food facts: conceptualization of nutritional fast food data for consumers and semantic web applications

Background

Fast food with its abundance and availability to consumers may have health consequences due to the high calorie intake which is a major contributor to life threatening diseases. Providing nutritional information has some impact on consumer decisions to self regulate and promote healthier diets, and thus, government regulations have mandated the publishing of nutritional content to assist consumers, including for fast food. However, fast food nutritional information is fragmented, and we realize a benefit to collate nutritional data to synthesize knowledge for individuals.

Methods

We developed the ontology of fast food facts as an opportunity to standardize knowledge of fast food and link nutritional data that could be analyzed and aggregated for the information needs of consumers and experts. The ontology is based on metadata from 21 fast food establishment nutritional resources and authored in OWL2 using Protégé.

Results

Three evaluators reviewed the logical structure of the ontology through natural language translation of the axioms. While there is majority agreement (76.1% pairwise agreement) of the veracity of the ontology, we identified 103 out of the 430 statements that were erroneous. We revised the ontology and publicably published the initial release of the ontology. The ontology has 413 classes, 21 object properties, 13 data properties, and 494 logical axioms.

Conclusion

With the initial release of the ontology of fast food facts we discuss some future visions with the continued evolution of this knowledge base, and the challenges we plan to address, like the management and publication of voluminous amount of semantically linked fast food nutritional data.

Healthy Eating Index-2015 Scores Vary by Types of Food Outlets in the United States

Diet quality in the United States is improving over time but remains poor. Food outlets influence diet quality and represent the environments in which individuals make choices about food purchases and intake. The objective of this study was to use the Healthy Eating Index-2015 (HEI-2015) to evaluate the quality of foods consumed from the four major outlets where food is obtained—stores, full-service restaurants, quick-services restaurants, and schools—and to assess changes over time. This cross-sectional study used 24 h dietary recall data from eight cycles (2003–2004 to 2017–2018) of the National Health and Nutrition Examination Survey (NHANES). Linear trend estimation was used to test for changes in HEI scores over time, and balanced repeated replicate weighted linear regression was used to test for differences in total and component scores between types of food outlets. Overall, Americans are not consuming a mix of foods from any major category of food outlet that aligns with dietary guidelines. The total score for schools (65/100 points) and stores (62/100 points) was significantly higher than full-service (51/100 points) and quick-service (39/100 points) restaurants (p < 0.0001). HEI scores significantly improved over time for schools (p < 0.001), including an increase in whole grains from less than 1 point in 2003–2004 to 7 out of 10 points in 2017–2018. In 2017–2018, schools received the maximum score for total fruits, whole fruits, and dairy. Continued research on strategies for improving the quality of foods consumed from restaurants and stores is warranted.

Knowledge and Attitude of Medical Students at the Universitas Sumatera Utara toward Lifestyle that Contributes to Type 2 Diabetes

BACKGROUND: Diabetes mellitus is a chronic metabolic disease with an increased blood glucose level. Lifestyle in the form of wrong diet and low or inadequate physical activity affect to type 2 diabetes. AIM: The purpose of this study was to determine the level of knowledge and attitude of medical students at the Universitas Sumatera Utara regarding diet and physical activity that contribute to type 2 diabetes. METHODS: Class 2017 medical students at the Universitas Sumatera Utara who met the inclusion and exclusion criteria were asked to participate as respondents in this cross-sectional study. Respondents were asked to answer online-based questionnaires containing 14 knowledge questions and 14 attitude statements about lifestyle towards type 2 diabetes. Knowledge scores equal to above 11 were categorized as good knowledge, and attitude scores equal to above 42 were categorized as good attitude. The data were presented as frequencies and percentage proportions using SPSS program version 22. RESULTS: Out of 255 class 2017 medical students, 72 students were respondents in this study. The results showed that the level of knowledge and attitude of medical students regarding diet that plays a role in type 2 diabetes in the good, moderate, and poor categories were 94.4%, 4.2%, 1.4% and 58.3%, 41.7%, 0%, respectively. The level of knowledge and attitude regarding physical activity that plays a role in type 2 diabetes in the good, moderate, and poor categories were 97.2%, 1.4%, 1.4% and 33.3%, 66.7%, 0%, respectively. Conclusions: In this study, it was shown that the knowledge and attitude of medical students at the Universitas Sumatera Utara towards eating pattern that contributes in type 2 diabetes were in line, namely the percentage of good categories was the highest percentage for each knowledge and attitude, but different results were found on the level of knowledge and attitude for physical activity.

Objectively Measured Built Environments and Cardiovascular Diseases in Middle-Aged and Older Korean Adults

This study assesses the association between the objectively measured built environment and cardiovascular diseases (CVDs) in 50,741 adults from the Korean Community Health Survey. The CVD outcomes of hypertension, diabetes, dyslipidemia, stroke, and myocardial infarction (MI) or angina were derived from self-reported histories of physician diagnoses. Using ArcGIS software and Korean government databases, this study measured the built environment variables for the 546 administrative areas of Gyeonggi province. A Bayesian spatial multilevel model was performed independently in two age groups (i.e., 40–59 years or ≥60 years). After adjusting for statistical significant individual- and community-level factors with the spatial associations, living far from public transit was associated with an increase in the odds of MI or angina in middle-aged adults, while living in neighborhoods in which fast-food restaurants were concentrated was associated with a decrease in the odds of hypertension and stroke. For adults 60 or older, living farther from public physical-activity (PA) facilities was associated with a 15% increased odds for dyslipidemia, compared with living in neighborhoods nearer to PA facilities. These findings suggest that creating a built environment that provides more opportunities to engage in PA in everyday life should be considered a strategy to reduce the prevalence of CVD.

Fast food consumption among young adolescents aged 12-15 years in 54 low- and middle-income countries

BACKGROUND

Most countries worldwide, especially low- and middle-income countries (LMICs), are facing an increasing prevalence of fast-food consumption and multiple burdens of malnutrition among young adolescents.

OBJECTIVE

To compare the prevalence of fast-food consumption among young adolescents in LMICs.

METHODS

We used data from the most recent Global School-Based Student Health Survey (2009-2015), which had been collected using a standardized questionnaire. The weighted prevalence and 95% confidential intervals of fast-food consumption were calculated overall and in subgroups stratified by age, sex, and nutritional status. The pooled overall and regional estimates were obtained using a random-effects model. Heterogeneity was assessed using the I2 statistic. The associated risk factors for fast-food consumption were explored using logistic regression analysis.

RESULTS

Our study comprised 153,496 young adolescents (46.90% boys) from 54 LMICs. Overall, approximately 55.2% (51.3-59.1%) of the adolescents consumed fast food at least 1 day per week, and 10.3% (8.3-12.4%) did so 4-7 days per week. The prevalence of fast-food consumption 4-7 days per week was lowest in the Americas (8.3%; 6.7-9.9%) and highest in Southeast Asia (17.7%; 2.3-33.2%). At a country level, the prevalence was lowest in Pakistan (1.5%; 1.0-2.0%) and highest in Thailand (43.3%; 40.4-46.1%). Furthermore, in subgroups stratified by nutritional status, the prevalence was lowest in the obesity group (6.6%; 4.5-8.7%). Factors such as age, sex, BMI, food insecurity, fruit consumption, vegetable consumption, soft-drink consumption, smoking, physical activity level, and sedentary behavior level were found to be correlated with fast-food consumption.

CONCLUSIONS

The identified high prevalence of fast-food consumption among young adolescents in LMICs indicates the urgent need to prioritize the implementation of healthy-diet promotion programs to improve adolescent health in these countries.

Association of dietary patterns with the newly diagnosed diabetes mellitus and central obesity: a community based cross-sectional study

Aim

The purpose of this study was to investigate the association of dietary patterns with the risk of insulin resistance (IR), diabetes mellitus (DM), and central obesity in China.

Methods

We performed a cross-sectional study on 1432 participants, aged 40–65 years in Hangzhou, Zhejiang province, China. Dietary intake was assessed using a semi-quantitative food frequency questionnaire.

Results

Factor analysis extracted four major dietary patterns: vegetable-fruits, rice–meat, seafood–eggs, and sweet–fast. The vegetable-fruits pattern was inversely associated with HOMA-IR (p < 0.001 in both genders), while sweet–fast food pattern was significantly associated with higher HOMA-IR (p = 0.002 in male, and p < 0.001 in female). The vegetables–fruits pattern was inversely correlated with visceral fat area (VFA) (p = 0.029 in males, and p = 0.017 in females), while sweet–fast food pattern presented a significant direct association (p < 0.001 in male) with VFA in males. There was no association observed between the rice–meat pattern or the seafood–eggs pattern and HOMA-IR or VFA. After adjustment for potential confounding factors, participants in the highest tertile of vegetable-fruits pattern showed a significantly lower risk of DM in both males and females (OR: 0.30, 95% CI: 0.13–0.70 in male, and OR: 0.28, 95% CI: 0.11–0.72 in female), and lower risk of central obesity was observed in males (OR: 0.50, 95% CI: 0.29–0.86 in male). Conversely, participants in the highest tertile of sweet–fast food pattern had higher risk of DM (OR: 2.58, 95% CI: 1.23–5.88 in male), and central obesity (OR: 2.85, 95% CI: 1.67–4.86 in male) only in male. While neither the rice–meat pattern nor the seafood–eggs pattern showed significant association with DM or central obesity in both genders.

Conclusions

Our findings indicated low risk of IR, DM, and central obesity with vegetable-fruits pattern while inverse relation with sweet–fast food pattern.

Associations of Food Outlet Densities with Obesity Measures Identify Fish and Chip Shops as a Uniquely Important Problem

Increases in the number of food outlets have been proposed as a key factor driving obesity. This study aimed to investigate the association between the densities of food establishments serving meals (excluding supermarkets and grocery stores), with body mass index (BMI), waist to hip ratio (WHR) and percentage of body fat among middle-aged adults in the UK. BMIs, WHR, %fat and socioeconomic factors were obtained from 456,079 individuals from the UK Biobank and averaged across 923 postcode districts (PD). The number of Fast-Food Restaurants (FFRs), Full-Service Restaurants (FSRs), delivery shops, takeaways, fish and chip shops, pubs and cafes were also obtained for each PD. We adjusted the obesity measures for deprivation level, education, employment, ethnicity, household size, household income and age. After adjustment, the density of fish and chip shops (per 1000 population) was positively associated with BMI and %fat for both sexes (males: BMI converted (exponentiated coefficient) β = 0.5, R² = 4.14%, p < 0.0001; %fat converted β = 0.8, R² = 3.32%, p < 0.0001; females: BMI converted β = 0.9, R² = 5.31%, p < 0.0001; %fat converted β = 1.4 R² = 4.65%, p < 0.0001). The densities of FFRs and delivery shops (per 1000 population) were not related to the adjusted obesity measures among males and females, except BMI in males where FFRs were significantly negatively associated. The densities (per 1000 population) of FSRs, pubs, cafes and total food outlets were all significantly inversely related to the obesity measures for both sexes. The number of fish and chip shops per 1000 individuals was significantly positively associated with obesity in middle-aged adults in the UK. A negative association between the other types of food outlet densities and the measures of obesity suggests access to such establishments is not a major driver of obesity. This is potentially because the food supplied at such establishments is not significantly less healthy than what is eaten elsewhere including at home (and may even be better). Paying attention only to fast food and/or full-service restaurants in intervention policy will likely not be effective. Policy intervention should potentially focus on the numbers of fish and chip shops and the deep-fried food served in such restaurants.
