A systems framework for implementing healthy food retail in grocery settings.

BACKGROUND: Food retailers can be reluctant to initiate healthy food retail activities in the face of a complex set of interrelated drivers that impact the retail environment. The Systems Thinking Approach for Retail Transformation (START) is a determinants framework created using qualitative systems modelling to guide healthy food retail interventions in community-based, health-promoting settings. We aimed to test the applicability of the START map to a suite of distinct healthy food marketing and promotion activities that formed an intervention in a grocery setting in regional Victoria, Australia. METHODS: A secondary analysis was undertaken of 16 previously completed semi-structured interviews with independent grocery retailers and stakeholders. Interviews were deductively coded against the existing START framework, whilst allowing for new grocery-setting specific factors to be identified. New factors and relationships were used to build causal loop diagrams and extend the original START systems map using Vensim. RESULTS: A version of the START map including aspects relevant to the grocery setting was developed ("START-G"). In both health-promoting and grocery settings, it was important for retailers to 'Get Started' with healthy food retail interventions that were supported by a proof-of-concept and 'Focus on the customer' response (with grocery-settings focused on monitoring sales data). New factors and relationships described perceived difficulties associated with disrupting a grocery-setting 'Supply-side status quo' that promotes less healthy food and beverage options. Yet, most grocery retailers discussed relationships that highlighted the potential for 'Healthy food as innovation' and 'Supporting cultural change through corporate social responsibility and leadership'. CONCLUSIONS: Several differences were found when implementing healthy food retail in grocery compared to health promotion settings. The START-G map offers preliminary guidance for identifying and addressing commercial interests in grocery settings that currently promote less healthy foods and beverages, including by starting to address business outcomes and supplier relationships.

The association between body weight indices, behavioral factors, and type 2 diabetes mellitus in Africa: A systematic review and meta-analysis of population-based epidemiological studies.

BACKGROUND AND AIM: Type 2 diabetes mellitus (T2DM) is a significant public health concern in Africa. While the associations between modifiable risk factors and T2DM are likely to be Africa-specific, their overall estimations have not been published. This study aimed to use systematic and meta-analytic methods to examine the strength of associations between modifiable risk factors and T2DM in Africa. METHODS AND RESULTS: A systematic search of literature published between January 2000 to March 2022 was conducted. The review included only population-based studies and data extracted from 57 studies. Of these, unadjusted data from 50 studies were included in meta-analysis. With considerable heterogeneity between studies, random-effect models were calculated to ascertain the odds ratios (OR) and 95% confidence intervals (CI) for the associations between obesity (OB) and overweight (OV), defined by BMI; central obesity (waist circumference (OB-WC), waist-to-hip-ratio (OB-WHR)), alcohol, fruit and vegetable consumption, smoking, physical activity (PA) and T2DM. Moderator effects of age, African regions, and urban/rural location were assessed. Risk factors associated with T2DM include BMI-OB [OR = 3.05, 95% CI: (2.58, 3.61)], BMI-OV [OR = 2.38, 95% CI: (1.51, 3.75)], and BMI-OV/OB [OR = 2.07, 95% CI: (1.82, 2.34)]; OB-WC [OR = 2.58, 95% CI: (2.09, 3.18)] and OB-WHR [OR = 2.22, 95% CI: (1.69, 2.92)]; PA [OR = 1.85, 95% CI: (1.50, 2.30)]. Significant moderator effects were not observed. CONCLUSION: Obesity defined by BMI and central obesity, but not behavioral risk factors were most strongly associated with T2DM in African populations, emphasizing the need for obesity prevention to limit the rise of T2DM.

A Scoping Review of Studies Evaluating the Healthiness of Street Food Vendors.

PURPOSE OF REVIEW: This scoping review investigates the available tools for monitoring the healthiness of the food sold at street food outlets globally. RECENT FINDINGS: Several tools were identified that have been used to evaluate the healthiness of street food outlets; however, these tools are not applicable globally, do not provide simple measures for evaluating the healthiness of foods sold, and generally have not been used across more than one study. The development of a comprehensive tool for measuring the healthiness of the street food environment that can be used across different jurisdictions and with different levels of resourcing is essential in order to understand the current street food environment and how it changes over time. As a major source of food in low- and middle-income countries globally, the street food environment is important to understand in order to know how it might help address the growing burden of diet-related diseases.

Association between urban-rural location and prevalence of type 2 diabetes and impaired fasting glucose in West Africa: a cross-sectional population-based epidemiological study.

OBJECTIVES: We investigated the association between urban/rural location and both type 2 diabetes mellitus (T2DM) and pre-diabetes among populations of five West African countries. DESIGN: Cross-sectional studies, using the WHO Stepwise (STEPs) survey data. SETTING: National representative data of both urban and rural areas from Benin, Burkina Faso, Ghana, Liberia and Mali. PARTICIPANTS: Adults comprising 15 468 participants (6774 men and 8746 women; 7663 urban and 7805 rural residents) aged between 25 and 64 years. RESULTS: The age and sex-adjusted prevalence of T2DM was 6.2% for urban areas and 2.5% for rural areas. The prevalence of impaired fasting glucose (IFG) was 6.6% for urban areas, and 3.0% for rural areas. No differences by sex were observed. The crude relative risk (RR) and 95% CI of T2DM and IFG in urban compared with rural areas were 2.69 (1.85 to 3.91) and 2.37 (1.53 to 3.66), respectively. This reduced to RR: 2.03, 95% CI (1.34 to 3.08) and RR: 2.04, 95% CI (1.27 to 3.28), respectively, after adjusting for covariables. CONCLUSION: The prevalence of both T2DM and IFG was more than two times as high in urban areas compared with rural areas in West Africa. Behavioural risk factors are common among urban populations, with ongoing urbanisation expected to drive increases in the prevalence of T2DM. These results could guide planning for T2DM screening, preventive strategies and resource allocation in West Africa.

Public Support for Nutrition-Related Actions by Food Companies in Australia: A Cross-Sectional Analysis of Findings from the 2020 International Food Policy Study.

Unhealthy food environments contribute to unhealthy population diets. In Australia, the government currently relies on voluntary food company actions (e.g., related to front-of-pack labelling, restricting promotion of unhealthy foods, and product formulation) as part of their efforts to improve population diets, despite evidence that such voluntary approaches are less effective than mandatory policies. This study aimed to understand public perceptions of potential food industry nutrition-related actions in Australia. An online survey was completed by 4289 Australians in 2020 as part of the International Food Policy Study. The level of public support was assessed for six different nutrition-related actions related to food labelling, food promotion, and product formulation. High levels of support were observed for all six company actions, with the highest support observed for displaying the Health Star Rating on all products (80.4%) and restricting children's exposure to online promotion of unhealthy food (76.8%). Findings suggest the Australian public is strongly supportive of food companies taking action to improve nutrition and the healthiness of food environments. However, given the limitations of the voluntary action from food companies, mandatory policy action by the Australian government is likely to be needed to ensure company practices align with public expectations.

Perceptions towards unhealthy food sponsorship in junior sports in Victoria, Australia.

OBJECTIVE: To explore Victorian parents' and club officials' engagement with, and attitudes towards, the sponsorship of junior sports by unhealthy food and beverage companies. METHODS: We conducted online surveys with 504 parents of children participating in junior sports and 16 semi-structured interviews with junior sports club officials (from clubs that accepted unhealthy food sponsorship) in Victoria, Australia. RESULTS: Most parents were concerned about children's exposure to sponsorship by unhealthy local (58% extremely, very or moderately concerned) and large food companies (63%) in junior sports. The views of sporting club officials were grouped into four themes: (1) the existing funding challenges for junior sports, (2) how junior sports sponsorship is community dependent, (3) how the perceived risks of sponsorship by unhealthy food companies are low and (4) the need for high-level regulations and support to transition towards healthier junior sports sponsorship. CONCLUSIONS: Transitioning towards healthier junior sports sponsorship may be hindered by insufficient funding models and low concern for such actions by community leaders. IMPLICATIONS FOR PUBLIC HEALTH: Policy actions from higher-level sporting governing bodies and governments are likely to be necessary to reduce harmful junior sports sponsorship, alongside restrictions on the marketing of unhealthy foods through other media and settings.

Awareness, use and understanding of nutrition labels among adults from five countries: Findings from the 2018-2020 International Food Policy Study.

Few studies have compared the effects of different front-of-package label (FOPL) systems in the 'real world'. This study assessed adults' awareness, use and understanding of nutrition facts labels (NFLs) and nationally implemented FOPLs such as Health Star Ratings (HSR), Traffic lights, and Guideline Daily Amounts (GDAs) in five countries, including before and after implementation of Mexico's warning FOPLs in 2020. Data were from the International Food Policy Study, an annual repeat cross-sectional study conducted in 2018-2020 among adults (N=64,032) in Australia, Canada, Mexico, the UK and the US. Self-reported awareness, use, and understanding of NFLs (in all five countries) and FOPLs (in Australia, Mexico, and UK) were assessed over time, between countries, and between NFLs and FOPLs. Most respondents in all countries reported seeing their country's NFLs (awareness) 'often' or 'all the time' across all three years, with one third to half of respondents using NFLs 'often' or 'all the time' (Australia: 43-45%; Canada: 47-50%; Mexico: 36-39%; UK: 32-34%; US: 47-49%), and approximately one half to two thirds finding NFLs 'easy' or 'very easy to understand' (56-57%; 67-69%; 51-54%; 48-51%; 70-71%). In 2020, awareness, use and self-reported understanding of the Warning FOPLs in Mexico were highest among all countries with a FOPL (p<0.001), whereas awareness and use were lowest for Australia's HSR (p<0.001). In countries with FOPLs, self-reported understanding was higher for FOPLs than NFLs, except for the GDA FOPL in Mexico. Only modest changes were observed over time. Warning FOPLs were associated with greater levels of self-reported awareness, use and understanding among adults compared to NFLs and GDA-based FOPLs. FOPLs implemented on a voluntary basis, such as Australia's HSR, may be less likely to be seen and used.

Protocol for a novel sodium and blood pressure reduction intervention targeting online grocery shoppers with hypertension - the SaltSwitch Online Grocery Shopping randomized trial.

BACKGROUND: High dietary sodium intake is a leading cause of hypertension. A major source of dietary sodium is salt added to processed food products available in retail food environments. The fast-growing online grocery shopping setting provides new opportunities for salt reduction interventions that support consumers in choosing healthier options. METHODS: The SaltSwitch Online Grocery Shopping randomized controlled trial is investigating the feasibility, acceptability, and effectiveness of a novel intervention for lowering salt consumption and blood pressure amongst people with hypertension who shop for groceries online. The intervention is based on a bespoke web browser extension that interfaces with a major retailer's online store to highlight and interpret product sodium content and suggest similar but lower-sodium alternatives. The primary outcome of interest is change in mean systolic blood pressure between individuals randomized (1:1) to the intervention and control (usual online shopping) arms at 12 weeks. Secondary outcomes are diastolic blood pressure, spot urinary sodium and sodium:potassium ratio, sodium purchases, and dietary intake. Intervention implementation and lessons for future uptake will be assessed using a mixed methods process evaluation. Participants with hypertension who shop online for groceries and exhibit high sodium purchasing behavior are being recruited across Australia. A target sample size of 1,966 provides 80% power (2-sided alpha = 0.05) to detect a 2 mm Hg difference in systolic blood pressure between groups, assuming a 15 mm Hg standard deviation, after allowing for a 10% dropout rate. DISCUSSION: This trial will provide evidence on an innovative intervention to potentially reduce salt intake and blood pressure in people with hypertension. The intervention caters to individual preferences by encouraging sustainable switches to similar but lower-salt products. If effective, the intervention will be readily scalable at low cost by interfacing with existing online retail environments.

Local government policies on healthy food promotion and obesity prevention: results from a national Australian survey.

OBJECTIVE: Local governments (LGs) often own or manage sport and recreation facilities and can promote health in these settings by implementing healthy food policies. The primary aim of this study was to assess the policies, attitudes and practices of Australian LGs relating to obesity prevention and the provision of healthy food in this setting. METHODS: In July 2020, all 539 Australian LGs were invited to complete a survey. We assessed LG priorities to obesity prevention, promoting healthy eating and public health as well as the presence of healthy food policies in sporting facilities. RESULTS: 203 (38%) LGs completed the survey. Improving public health was a high priority, while obesity prevention and promoting healthy eating were a medium priority. 22% of LGs reported that the priority given to promoting healthy food had increased over the previous year and stayed the same at 65%. Ten per cent of LGs had a healthy food and drink policy in sporting facilities, with 32% reporting having made changes without a policy. LGs located in major cities, with larger populations and with more facilities reported having made more healthy changes at their facilities. CONCLUSION: Promoting health is a priority for LGs across Australia, but very few have policies relating to the food environments in their sporting facilities. IMPLICATIONS FOR PUBLIC HEALTH: Ongoing monitoring is important to assess changes over time and identify LGs where greater support is required.

Food industry perspectives on potential policies targeting unhealthy food and beverage price promotions in Australian supermarkets.

Current supermarket price promotions are likely to encourage unhealthy diets, leading some governments to recently endorse restrictions on price promotions for unhealthy food and beverages. However, little is known about the likely industry response to policy action in this area. The aim of this study was to understand how potential government policies targeting food and beverage price promotions in supermarkets are perceived by food industry stakeholders in Australia. Twelve semi-structured in-depth interviews were conducted with current and former employees of major food manufacturers and food retailers as well as other industry experts with experience related to price promotion practices in the Australian supermarket setting. Data were analysed deductively based on Lewin's organisational change theories and inductively to highlight forces that might drive or restrain change.From an industry perspective, forces likely to create industry opposition to implementation of price promotion policy included: fear of losing competitive advantage; potential financial loss for food retailers and their suppliers; a perception that restrictions on price promotions for unhealthy products will not impact health; and a perception of increased financial cost to consumers. Forces perceived to drive implementation of a policy that would benefit public health included: mandatory regulation; extensive compliance monitoring; support for promoting healthy products; consumer education; and sufficient lead time and support from retailers for implementation. These forces, and the way in which they interact, need to be actively considered as part of efforts to change the healthiness of food and beverage price promotions in supermarkets.

Change in the Healthiness of Foods Sold in an Australian Supermarket Chain Following Implementation of a Shelf Tag Intervention Based on the Health Star Rating System.

INTRODUCTION: Most people in Australia buy most of their food in supermarkets. Marketing techniques promoting healthy foods in supermarkets can be important to encourage healthy eating at a population level. Shelf tags that highlight the healthiness of products have been identified as one such promising initiative. The aim of this study was to assess changes in the healthiness of foods sold in an Australian supermarket chain following implementation of a shelf tag intervention based on the Australian Health Star Rating (HSR) system. METHODS: A controlled, non-randomised trial was undertaken in seven supermarkets (intervention: n = 3; control: n = 4) of a single chain in Victoria, Australia, over 12 weeks (4 weeks baseline, 8 weeks intervention period) between August and November 2015. The intervention involved provision of a shelf tag indicating the HSR of all packaged products that scored 4.5 or 5 stars ('high-HSR products') using the Australian HSR system. Posters indicating the healthiness of fresh fruits and vegetables (not eligible for an HSR rating, as they are not packaged) were also installed. Weekly per store sales data were provided by the retailer. In an intention-to-treat analysis (with intervention status of individual products based on their eligibility to be tagged), the proportion (%) of all 'high-HSR' packaged food sold and the volume of key nutrients (saturated fat, total fat, sodium, total sugar, protein, carbohydrates and energy) per 100 g sold were assessed. Difference-in-difference analyses were conducted to determine the difference between intervention and control stores in terms of mean outcomes between baseline and intervention periods. Customer exit surveys (n = 304) were conducted to evaluate awareness and use of the shelf tags and posters. RESULTS: The proportion of 'high-HSR products' sold increased in the intervention period compared to the baseline period in each of the three intervention stores (average increase of 0.49%, 95% CI: -0.02, 0.99), compared to a decrease of -0.15% (-0.46, 0.15) in control stores (p = 0.034). The overall increase in intervention compared to control stores (difference-in-difference) of 0.64% represents an 8.2% increase in the sales of 'high-HSR products'. Sales of total sugar, total fat, saturated fat, carbohydrates, sodium, protein and total energy in packaged food all decreased significantly more in intervention stores compared to control stores. Sales of fresh fruits and vegetables decreased in intervention stores compared to control stores. Customer surveys found that 34.4% noticed the shelf tags. Of those who noticed the tags, 58% believed the shelf tags influenced their purchases. CONCLUSIONS: With this study, we found that the use of shelf tags that highlight the healthiest packaged foods in a supermarket setting showed promise as a mechanism to improve the healthiness of purchases. Opportunities to scale up the intervention warrant exploration, with further research needed to assess the potential impact of the intervention on overall population diets over the longer term.

Effect of age and sex on the associations between potential modifiable risk factors and both type 2 diabetes and impaired fasting glycaemia among West African adults.

BACKGROUND: Type 2 diabetes mellitus (T2DM) is becoming one of the leading causes of morbidity and mortality worldwide, including among Africans. Knowledge of the association between traditional risk factors and both diabetes and pre-diabetes, and whether these differ by age and sex, is important for designing targeted interventions. However, little is known about these associations for African populations. METHODS: The study used data from WHO STEPS surveys, comprising 15,520 participants (6,774 men and 8,746 women) aged 25-64 years, from 5 different West African countries, namely Burkina Faso (4,711), Benin (3,816), Mali (1,772), Liberia (2,594), and Ghana (2,662). T-test and chi-square tests were used to compare differences in the prevalence of traditional risk factors for both sexes. Multinomial logistic regression was conducted to ascertain the relative risks (RR) and 95% confidence intervals (CI) for both T2DM and impaired fasting glucose (IFG) relating to each risk factor, including obesity [defined by BMI, waist circumference (WC), waist-to-hip ratio (WHR), and waist-to-height ratio (WHtR)], high blood pressure (HBP), fruit and vegetable consumption, physical inactivity, alcohol consumption, and smoking. Models for each of these traditional risk factors and interactions with age and sex were fitted. RESULTS: Factors associated with T2DM and IFG were age, obesity [defined by BMI, WC, WHtR, and WHR], HBP, smoking, physical inactivity, and fruit and vegetable consumption (p < 0.05). Analysis of interaction effects showed few significant differences in associations between risk factors and T2DM according to age or sex. Significant interaction with age was observed for HBP*age and T2DM [RR; 1.20, 95% CI: (1.01, 1.42)) (p = 0.04)], WHtR*age and T2DM [RR; 1.23, 95% CI: (1.06, 1.44) (p = 0.007)] and WHR*age and IFG [RR: 0.79, 95% CI: (0.67, 0.94) (p = 0.006)]. Some interactions with age and sex were observed for the association of alcohol consumption and both IFG and T2DM, but no clear patterns were observed. CONCLUSION: The study found that with very few exceptions, associations between traditional risk factors examined and both IFG and T2DM did not vary by age or sex among the West African population. Policies and public health intervention strategies for the prevention of T2DM and IFG should target adults of any age or sex in West Africa.

Cost-Benefit and Cost-Utility Analyses to Demonstrate the Potential Value-for-Money of Supermarket Shelf Tags Promoting Healthier Packaged Products in Australia.

The supermarket environment impacts the healthiness of food purchased and consumed. Shelf tags that alert customers to healthier packaged products can improve the healthiness of overall purchases. This study assessed the potential value-for-money of implementing a three-year shelf tag intervention across all major supermarket chains in Australia. Cost-benefit analyses (CBA) and cost-utility analyses (CUA) were conducted based on results of a 12-week non-randomised controlled trial of a shelf tag intervention in seven Australian supermarkets. The change in energy density of all packaged foods purchased during the trial was used to estimate population-level changes in mean daily energy intake. A multi-state, multiple-cohort Markov model estimated the subsequent obesity-related health and healthcare cost outcomes over the lifetime of the 2019 Australian population. The CBA and CUA took societal and healthcare sector perspectives, respectively. The intervention was estimated to produce a mean reduction in population body weight of 1.09 kg. The net present value of the intervention was approximately AUD 17 billion (B). Over 98% of the intervention costs were borne by supermarkets. CUA findings were consistent with the CBA-the intervention was dominant, producing both health benefits and cost-savings. Shelf tags are likely to offer excellent value-for-money from societal and healthcare sector perspectives.

Consumption Frequency and Purchase Locations of Foods Prepared Outside the Home in Australia: 2018 International Food Policy Study.

BACKGROUND: Foods prepared outside the home (e.g., fast-food chains, restaurants) represent increasing proportions of diets worldwide, and have been associated with higher energy intakes and BMIs. To improve the healthiness of population diets, it is important to understand patterns of consumption of these foods, and whether related policy measures are effective. OBJECTIVES: This study aimed to identify the frequency and sources of consumption of foods prepared outside the home in Australia, and to understand the impact of nutrition information in restaurants on related food choices. METHODS: Data were from a web-based survey (the International Food Policy Study) completed in 2018 by Australian adults aged ≥18 years (n = 4103). The number of meals prepared outside the home, their purchase locations, and the extent to which nutrition information was noticed and influenced purchasing decisions were each analyzed by sociodemographic characteristics and BMI, with linear models also adjusted for sex, age group, education, ethnicity, and BMI. RESULTS: An average of 2.73 (95% CI, 2.61-2.86) meals per week were prepared outside the home, with higher frequencies among men, younger ages, and more highly educated participants. A wide variety of sources for these foods was observed, with fast-food outlets being most common. Around one-quarter of all foods prepared outside the home were delivered. A small percentage (14.9%; 95% CI, 13.3%-16.7%) of participants reported noticing nutrition information, but among those who did, around half reported that it influenced their behavior. CONCLUSIONS: Foods prepared outside the home are commonly purchased in Australia, particularly by young adults, from a variety of outlet types. While current menu energy labeling regulations may provide some population health benefit, a broader policy focus on foods prepared outside the home is needed as part of efforts to improve population diets.

Self-Reported Impacts of the COVID-19 Pandemic on Diet-Related Behaviors and Food Security in 5 Countries: Results from the International Food Policy Study 2020.

BACKGROUND: The coronavirus disease 2019 (COVID-19) pandemic has impacted many aspects of daily life, including dietary intake; however, few studies have reported its impacts on dietary behaviors and food security across multiple countries. OBJECTIVES: We examined self-reported impacts of COVID-19 on food behaviors, food security, and overall diet healthfulness in 5 countries. METHODS: Adults aged 18-100 years (n = 20,554) in Australia, Canada, Mexico, the United Kingdom, and the United States completed an online survey in November and December 2020 as part of the International Food Policy Study, an annual, repeat cross-sectional survey. Survey measures assessed perceived impacts of the COVID-19 pandemic on eating food prepared away from home, having food delivered from a restaurant, and buying groceries online, as well as perceived food security and overall diet healthfulness. Regression models examined associations between each outcome and sociodemographic correlates. RESULTS: Across all countries, 62% of respondents reported eating less food prepared away from home due to the pandemic, while 11% reported eating more. Some participants reported having less food delivered from a restaurant (35%) and buying fewer groceries online (17%), while other respondents reported more of each (19% and 25%, respectively). An average of 39% reported impacts on their food security, and 27% reported healthful changes to their overall diet. The largest changes for all outcomes were observed in Mexico. Participants who were younger, ethnic minorities, or had lower income adequacy tended to be more likely to report food-related changes in either direction; however, these relationships were often less pronounced among respondents in Mexico. CONCLUSIONS: Respondents reported important changes in how they sourced their food during the pandemic, with trends suggesting shifts towards less food prepared away from home and more healthful diets overall. However, changes in diet and food behaviors occurred in both healthful and less healthful directions, suggesting that dietary responses to the pandemic were highly variable.

Quantifying the overall impact of an early childhood multi-behavioural lifestyle intervention.

BACKGROUND: The overall impact of interventions targeting multiple behaviours remains largely unexplored. OBJECTIVES: This study adopted an integrative lifestyle pattern analysis approach to assess the overall effectiveness of an early childhood intervention on change across multiple behaviours. METHODS: The Melbourne INFANT program was a 15-month cluster-randomized controlled trial involving 4-month-old infants and their parents at baseline in 2008 (n = 542). The intervention included six education sessions helping parents to promote a healthy diet, physical activity and limit sedentary behaviour in their infants. Participants were followed-up twice post-intervention, at ages 3.6 (2011) and 5 years (2013), to assess sustained effects of the intervention. Previous principal component analyses identified two lifestyle patterns from dietary intake, outdoor time and television viewing time. Random effect linear regression models were conducted to assess the impact of the intervention on lifestyle patterns. RESULTS: The intervention group had a lower 'Discretionary consumption and TV' lifestyle pattern score than the control group at all time points with adjusted mean difference: -0.29, 95% CI -0.49, -0.09, p = 0.004 post-intervention at age 1.5 years; -0.29, 95% CI -0.54, -0.04, p = 0.02 at the first follow-up (age 3.6 years); and -0.21, 95% CI -0.43, 0.01, p = 0.06 at the second follow-up (age 5.0 years). No evidence of between-group differences was found for the 'Fruit, vegetables and outdoor' lifestyle pattern score. CONCLUSION: This early childhood intervention designed to promote change in more than one obesity-related behaviour was effective in improving correlated unhealthy lifestyle behaviours. Lifestyle pattern analysis is a useful and interpretable approach for evaluating multi-behavioural interventions.

Price promotions offered by quick service restaurants in Australia: analysis from an obesity prevention perspective.

OBJECTIVE: To assess the price promotions offered by major quick service restaurant (QSR) chains in Australia from an obesity prevention perspective. DESIGN: Cross-sectional audit of ten of the largest QSR chains in Australia. We collected information regarding temporary price promotions and 'combination deals' offered by each chain over thirteen consecutive weeks in 2019-2020. We assessed the type of promotions, the magnitude of discount, and the energy content and healthiness of items promoted (based on Victorian Government criteria). SETTING: Melbourne, Australia. PARTICIPANTS: Ten major QSR chains. RESULTS: Temporary price promotions (n 196) and combination deals (n 537 on regular menus, n 36 on children's menus) were observed across the ten selected QSR chains. In relation to temporary price promotions, the mean magnitude of discount for main menu items (n 75) was 41·7 %. The price reductions and energy content of combination deals varied substantially the by chain, the meal size and the sides/drinks selected as part of the 'deal'. When the lowest-energy options (e.g. small chips, small sugar-free drink) were included as part of each combination deal, the mean energy content was 2935 kJ, compared to 5764 kJ when the highest-energy options (e.g. large fries, large sugar-sweetened drink) were included. Almost all available products were classified as unhealthy. CONCLUSION: Price promotions are ubiquitous in major QSR chains in Australia and provide incentives to consume high levels of energy. The action to restrict price promotions on unhealthy foods and ensure lower-energy default items as part of combination deals should be included as part of efforts to improve population diets and address obesity in Australia.

Implementation and sales impact of a capacity building intervention in Australian sporting facility food outlets: a longitudinal observational study.

Background: Few studies have explored behavioural and financial impacts of retail initiatives after 2 years to address the unhealthy food environments common in local government sporting settings. Aims: To evaluate the impact of a 2-year local government capacity building intervention in sporting facility food outlets on (1) the healthiness of refrigerated drink choices available and visible to customers, (2) healthiness of refrigerated drinks sold and (3) refrigerated drink revenue. Methods: 52 sporting facilities within 8 local governments from Victoria, Australia, participated in an intervention between March 2018 and February 2020 by limiting 'red' (least healthy) drinks to ≤20% of refrigerator display and increasing 'green' (healthiest) drinks to ≥50% of display. Mixed models assessed changes in mean percentage of 'red', 'amber' and 'green' drinks displayed over time, compared with baseline.Facilities provided electronic weekly itemised sales data (December 2015 to February 2020). Weekly volume of 'red' or 'green' drinks sold as a proportion of total drinks sold, and total refrigerated drinks revenue were compared preimplementation and postimplementation using mixed models (seasonal facilities), and mixed-effect interrupted time series models (non-seasonal facilities). Results: Display of 'red' drinks decreased by mean -17.1 percentage points (pp) (95% CI -23.9 to -10.3) and 'green' drinks increased 16.1 pp (95% CI 9.30, 22.9) between baseline and 18-month audits.At nine seasonal facilities, compared with the summer preimplementation, the mean volume of 'red' drinks sold decreased by -19.0 pp (95% CI -28.6, to -9.51) and refrigerated drink revenue decreased by-AU$81.8 (95% CI -AU$123 to -AU$40.8) per week. At 15 non-seasonal facilities, by February 2020, the volume of 'red' drinks sold decreased on average by -11.0 pp (95% CI -21.6 to -0.41) with no change in drink revenue. Conclusion: Reducing the display of unhealthy drinks can be an effective public health policy to improve the healthiness of customer purchases, provided there is consideration of potential impacts on revenue.

A Systematic Review of Health Promotion Programs to Improve Nutrition for People with Intellectual Disability.

PURPOSE OF REVIEW: To investigate the type and effectiveness of health promotion programs designed to improve nutrition for people with intellectual disability. This review also sought to highlight gaps in the evidence by mapping interventions to the socio-ecological model. RECENT FINDINGS: To date, reviews on health promotion programs for people with intellectual disability have focused on individualised weight management interventions and behaviour change techniques. No reviews have focused solely on nutrition or considered a broader range of interventions and policies targeted beyond the individual. This review found that health promotion interventions to date were predominantly at the individual level of the socio-ecological model and of varying effectiveness. Of the non-individually focused interventions, those targeting the physical environment or considering multiple socio-ecological levels achieved the greatest improvements in nutrition outcomes. Nutrition and obesity prevention research and policy need to include intellectual disability as part of equity considerations, while intellectual disability policy needs to consider the broader food environment.

A Proposed Research Agenda for Promoting Healthy Retail Food Environments in the East Asia-Pacific Region.

PURPOSE OF REVIEW: This paper aimed to summarise existing literature on strategies to improve the healthiness of retail food environments in the East Asia and Pacific (EAP) region, and propose a prioritised research agenda on this topic. RECENT FINDINGS: Little research on retail food environments has been conducted in the EAP region. Several approaches for measuring retail food environments were identified, although none have been tailored to the EAP context. A small number of policies and initiatives to promote healthy retail food environments have been implemented in EAP. Lessons learnt from successful implementation of initiatives in other regions could be applied in EAP. Retail food environments have a strong influence on food choices and health outcomes. Research can contribute to efforts to improve the healthiness of retail food environments in EAP by (1) describing the current state of retail food environments to highlight areas of good practice and concern and (2) identifying policies and initiatives that are likely to be effective, and mechanisms for their successful implementation.
