Dimensions of the diet-exercise relationship in later life: A qualitative study.

OBJECTIVE: Diet and physical activity are two lifestyle behaviours that are critical for healthy ageing. The aim of this study was to explore how older adults negotiate dietary and physical activity decisions to identify areas of intersection between these two behaviours and inform health promotion interventions targeting both diet and exercise. METHODS: This exploratory study utilised a novel data collection approach that involved lay interviewers recruiting their peers to (i) participate in two interviews over a period of six months and (ii) make notes on their thoughts relating to diet and physical activity. Participants were 75 adults aged 60+ years in Western Australia (n = 64 females). RESULTS: Three primary themes were identified: (i) the importance but difficulty of achieving energy balance; (ii) issues relating to managing food intake before, during, and after physical activity; and (iii) reciprocal opportunities for eating and physical activity. CONCLUSIONS: Diet and physical activity are linked in complex ways, highlighting the need for multi-factorial interventions. IMPLICATIONS FOR PUBLIC HEALTH: When developing communications strategies designed to encourage older people to both improve their diets and increase their physical activity, consideration could be given to leveraging existing perceived alignments between healthy eating and being active.

Patterns of Sun Protection Behaviours among Australian Adolescents and Adults over a Six-Year Period.

The major cause for skin cancer is the excessive and unprotected exposure to ultraviolet radiation (UVR), which can be prevented by engaging in sun protection behaviours. As longitudinal studies on both adolescents' and adults' performances of sun protection behaviours are limited, the current study aimed to investigate changes in sun protection in these population segments in Western Australia, a region with high annual UVR. During six summer seasons (2015/16 to 2020/21), cross-sectional surveys were conducted among 1806 adolescents (14 to 17 years old) and 1808 adults (18-45 years old), investigating the frequency of five sun protection behaviours (wearing clothing, applying sunscreen, wearing a hat, wearing sunglasses, and seeking shade) and sun avoidance (staying indoors). Over the six-year period, staying indoors increased in both groups. Among adolescents, a decrease in wearing clothing and sunglasses and an increase in seeking shade was demonstrated, and hat and sunscreen use remained relatively stable. Among adults, an increase in sunscreen use was shown, whereas all other sun-related behaviours remained consistent over the six-year period. The results from this study can provide directions for health communications focusing on improving sun protection behaviours among both adolescent and adult populations.

The ORIGINS Project Biobank: A Collaborative Bio Resource for Investigating the Developmental Origins of Health and Disease.

Early onset Non-Communicable Diseases (NCDs), including obesity, allergies, and mental ill-health in childhood, present a serious and increasing threat to lifelong health and longevity. The ORGINS Project (ORIGINS) addresses the urgent need for multidisciplinary efforts to understand the detrimental multisystem impacts of modern environments using well-curated large-scale longitudinal biological sample collections. ORGINS is a prospective community birth cohort aiming to enrol 10,000 pregnant people and follow each family until the children reach 5 years of age. A key objective is to generate a comprehensive biorepository on a sub-group of 4000 families invited to contribute blood, saliva, buccal cells, urine, stool, hair, house dust, cord blood, placenta, amniotic fluid, meconium, breastmilk, and colostrum over eight timepoints spanning the antenatal period and early childhood. Uniquely, ORIGINS includes a series of nested sub-projects, including interventions and clinical trials addressing different aspects of health. While this adds complexity as the project expands, it provides the opportunity for comparative studies. This research design promotes a multidisciplinary, multisystem approach to biological sample collection, analysis, and data sharing to ensure more integrated perspectives and solutions. This paper details the evolving protocol of our collaborative biobanking concept. Further, we outline our future visions for local, national, and ultimately international, comparative, and collaborative opportunities to advance our understanding of early onset NCDs and the opportunities to improve health outcomes for future generations.

The ability of five different front-of-pack labels to assist Australian consumers to identify healthy versus unhealthy foods.

OBJECTIVE: The aim of this study was to assess the relative ability of different interpretive front-of-pack food labels to alert consumers to both healthier and unhealthier options to inform their food choices. METHODS: One thousand Australians completed an online experiment where they rated the nutritional quality of sets of fictional products pre- and post-randomisation to one of five front-of-pack labels: Health Star Rating, Multiple Traffic Lights, Nutri-Score, Reference Intakes and Warning Label. Two sample z-tests were used to assess the ability of each label to facilitate the correct identification of the least and most healthy product options. RESULTS: The Nutri-Score was superior in assisting respondents to identify both the healthiest and unhealthiest options. The Health Star Rating ranked second for both outcomes, followed by the Multiple Traffic Lights. CONCLUSIONS: Results reinforce the role of interpretive front-of-pack labels in assisting consumers to understand the nutritional quality of food products and suggest spectrum labels may provide superior utility in assisting consumers to identify both the most and least nutritious products from among available product options. IMPLICATIONS FOR PUBLIC HEALTH: The strongest performance of a highly interpretive front-of-pack label (Nutri-Score) featuring colour in a summary indicator suggests potential strategies for enhancing the performance of the Health Star Rating.

Exploring grandparents' receptivity to and preferences for a grandchild nutrition-focused intervention: A qualitative study.

OBJECTIVE: Interventions promoting healthy eating in children typically overlook the critical role of grandparent caregivers. Utilising a co-design approach, this study (i) assessed the receptiveness of grandparents to a nutrition-focused resource aimed at promoting healthy eating in their grandchildren and (ii) explored grandparents' preferences for resource delivery and dissemination. METHODS: Seventy-nine grandparents (58% female; mean age=69.37 years) who were secondary carers to a grandchild aged 3-12 years participated in one of 10 focus groups. Focus group transcripts were imported into NVivo for coding and semantic thematic analysis. RESULTS: The vast majority of focus groups (n=9) were receptive to receiving a nutrition-focused resource. Participants indicated that such a resource should contain strategies that help grandparents promote healthy eating in their grandchildren rather than outline what grandchildren should be fed. A range of delivery (pamphlets, seminars and fridge magnets) and dissemination (online, email) methods were suggested. CONCLUSIONS: A nutrition resource that equips grandparents with the strategies they need to promote healthy eating in their grandchildren would likely be welcomed. IMPLICATIONS FOR PUBLIC HEALTH: Results provide program developers with the preliminary information required to tailor childhood lifestyle interventions to the needs of grandparents, thus helping increase acceptability and uptake.

Predicting Perceived Problems in Self-Administered 24-Hour Dietary Recalls: A Quantitative Think-Aloud Study Comparing Automated Self-Assisted 24-Hour Dietary Assessment Tool (ASA24®) and INTAKE24© in University Students.

Demographic and psychosocial factors concerning dietary assessment error have been explored, but few studies have investigated the perceived problems experienced when completing dietary recalls. The aim of this research was to (i) compare the perceived problems encountered in two commonly used self-administered 24-hour dietary recall (24HR) programs (INTAKE24© and ASA24®) and (ii) explore whether mindful and habitual eating are associated with perceived problems during dietary recall. A randomised quantitative crossover design and think-aloud methodology were employed. Undergraduate university students (N = 55, Mage = 25.5, SD = 8.2, 75% female) completed a food habits and mindfulness questions pre-program, one 24HR (whilst thinking aloud), and a systems usability scale post-program. A week later, they completed the other 24HR (whilst thinking aloud). During a pilot, a coding frame of perceived problems was devised to quantify participants' perceived problems. INTAKE24© generated significantly fewer perceived problems across all categories compared to ASA24® (17.2 vs. 33.1, p < 0.001). Of the participants, 68% reported a preference for INTAKE24© over ASA24®. Hierarchical multiple regression showed that habits and systems usability were significant predictors of perceived problems for INTAKE24© only. No significant predictors were found for ASA24®. The results provide insight into perceived problems people may encounter when using 24HR tools.

Polish Consumers' Understanding of Different Front-of-Package Food Labels: A Randomized Experiment.

Dietary practices are a key behavioral factor in chronic disease prevention; one strategy for improving such practices population-wise involves front-of-package labels (FoPL). This online randomized study, conducted in a quota-based sample of 1159 Polish adults (mean age = 40.9 ± 15.4 years), assessed the objective understanding of five FoPL: Health Star Rating, Multiple Traffic Lights, NutriScore, Reference Intakes (RI) and Warning Label. Objective understanding was evaluated by comparing results of two nutritional quality ranking tasks (without/with FoPL) using three food categories (breakfast cereals, cakes, pizza). Associations between FoPL exposure and objective understanding were assessed via multivariable ordinal logistic regression. Compared to RI and across food categories, significant improvement in objective understanding was seen for NutriScore (OR = 2.02; 95% CI: 1.41-2.91) and Warning Label (OR = 1.61; 95% CI: 1.12-2.32). In age-stratified analyses, significant improvement in objective understanding compared to RI emerged mainly among adults aged 18-30 years randomized to NutriScore (all food categories: OR = 3.88; 95% CI: 2.04-7.36; cakes: OR = 6.88; 95% CI: 3.05-15.51). Relative to RI, NutriScore was associated with some improvement in objective understanding of FoPL across and within food categories, especially among young adults. These findings contribute to the ongoing debate about an EU-wide FoPL model.

Nutri-Score: The Most Efficient Front-of-Pack Nutrition Label to Inform Portuguese Consumers on the Nutritional Quality of Foods and Help Them Identify Healthier Options in Purchasing Situations.

Several studies have identified Front-of-Pack Nutrition Labels (FoPLs) as a promising strategy to improve the nutritional quality of consumers' food choices and encourage manufacturers to offer healthier products. This study aims to fill the evidence gap regarding the most effective FoPL among the Portuguese population. In total, 1059 Portuguese participants were recruited through a web panel provider and asked to declare their intended food choices and to rank three sets of products (pizza, cakes and breakfast cereals) according to their nutritional quality, first in the absence of any labelling, and then with a FoPL displayed on-pack (five FoPLs tested). Finally, participants were asked to answer nine statements related to perceptions of FoPLs. Results showed that participants improved their food choices, depending on the FoPL and the food category. All FoPLs led to a higher percentage of correct responses on the ranking task compared to the no label condition. The Nutri-Score was among the FoPLs producing the greatest improvement across all food categories compared to the reference intakes (OR = 6.45 [4.43-9.39], p-value < 0.0001) and facilitating the highest percentage to correctly rank products according to nutritional quality. This study suggests that, among the available options, Nutri-Score is the most efficient FoPL to inform Portuguese consumers of the nutritional quality of foods and help them identify healthier options in mock purchasing situations.

The role of colour and summary indicators in influencing front-of-pack food label effectiveness across seven countries.

OBJECTIVE: Many countries are considering the implementation of front-of-pack nutrition labels as a strategy to address high and increasing levels of overweight and obesity. A growing body of work demonstrates the superiority of labels that use colour and/or provide a summary indicator of product healthiness to enhance comprehension. However, previous studies have been confounded in determining the relative effectiveness of these two attributes by comparing labels that also differ in other ways. The present study tested labels that varied only on use of colour and/or reliance on a summary indicator across an international sample to provide unique insights into the relative importance of these attributes. DESIGN: Participants were randomised to see one of four variations of the Health Star Rating label that differed on the basis of use of colour and sole provision of a summary indicator. SETTING: Australia, Canada, China, India, New Zealand, the UK and the USA. PARTICIPANTS: Adults (n 7545) in seven countries were exposed to online choice tasks requiring them to select a preferred breakfast cereal and then nominate the healthiest cereal. RESULTS: Overall, the coloured versions, and particularly the one with just a summary indicator, outperformed the monochrome version that included nutrient-specific information. However, there were some differences by country, with results from Canada and China indicating superior outcomes for monochrome labels and those providing nutrient-specific information. CONCLUSIONS: The results highlight the importance of colour, but suggest that the introduction of front-of-pack nutrition labels should be preceded by country-specific formative testing to identify potential differences in outcomes.

Predictors of uptake of general and tailored services to improve employee health and wellbeing.

ISSUE ADDRESSED: Healthy workplace programs can improve employee health and wellbeing. However, there is little research on how they are adopted by organisations. The study aimed to investigate uptake and predictors of service use amongst organisations utilising a comprehensive government-funded healthy workplace program. METHODS: Employees taking part in the Healthier Workplaces WA program can access general services (ie, basic information on workplace health and wellbeing) and tailored services (ie, personalised support on implementing changes). A sample of 358 eligible program participants from 204 organisations completed a service experience survey 6 months after engaging with any service. Predictors of service use were analysed using a Kruskal-Wallis H test. RESULTS: On average, respondents accessed 3.4 (out of 7) services. General services were accessed more frequently than tailored services. The Kruskal-Wallis H test showed that respondents working in Human Resources or Health and Safety and those from large organisations were more likely to access a greater range of services compared to employees in other roles and those working in small to medium organisations. Additionally, greater perceived support from management or co-workers was associated with greater service use. CONCLUSIONS: Respondents reported accessing general services more than tailored services. Service use was greater amongst those who perceived greater support from their managers and/or co-workers, those who worked in large organisations and those who worked in HR/OHS. SO WHAT?: These findings are informative for practitioners assisting organisations to improve health and wellbeing initiatives and service providers interested in increasing service uptake. A mix of general and tailored services is likely to be useful in building employees' capacity to increase health and wellbeing in their workplace. Support from management and co-workers is an important facilitator, and small organisations may require more focussed targeting due to the lower tendency to engage with these programs and increased benefits.

Grandparents' perceptions of the barriers and strategies to providing their grandchildren with a healthy diet: A qualitative study.

Grandparents are playing an increasingly important role in shaping their grandchildren's nutritional environment. Evidence-based interventions tailored to grandparents thus constitute a potential means of promoting healthy eating among children. For such interventions to be effective, they must account for the unique issues encountered by grandparents. However, research examining the potential needs of grandparents is limited. The present study thus explored (i) grandparents' perceptions of the barriers to providing their grandchildren with healthy food and minimizing consumption of unhealthy food and (ii) the strategies grandparents believe help increase their grandchildren's consumption of healthy food and reduce intake of unhealthy food. Seventy-nine grandparents, each of whom provided care to at least one grandchild aged 3-12 years, participated in one of ten focus groups. Transcripts from each of the groups were imported into NVivo for qualitative coding and semantic thematic analysis. The food preferences of their grandchildren, the promotion of unhealthy food consumption by their grandchildren's parents, advertising of unhealthy food, and peer pressure were the most frequently cited barriers to healthy food consumption. Grandparents reported using multiple strategies to increase their grandchildren's fruit and vegetable consumption and minimize unhealthy food intake. The most common were disguising vegetables, making fruit and vegetables appealing, managing child eating (e.g., limiting access to unhealthy food), saying no to requests for unhealthy food, involving grandchildren in meal planning and cooking, and using rewards. Findings suggest that grandparents may need support with managing food preferences and navigating and negotiating complex relations with parents regarding child feeding.

Objective understanding of the Nutri-score front-of-pack label by European consumers and its effect on food choices: an online experimental study.

BACKGROUND: The effectiveness of Front-of-Pack nutrition Labels (FoPLs) may be influenced by national context. In light of the ongoing efforts to harmonize FoPLs across Europe, this study aimed to compare the effectiveness of five FoPLs (Health Star Rating system, Multiple Traffic Lights, Nutri-Score, Reference Intakes, Warning symbols) on consumer understanding and food choice in 12 European countries. METHODS: In 2018-2019, for three food categories, approximately 1000 participants per country were asked to select which food they would prefer to purchase between three products with distinct nutritional quality profiles, and then to rank the products by nutritional quality. Participants (N = 12,391 in total) completed these tasks first with no FoPL and then, after randomization to one of the five FoPLs, with a FoPL on the food packages. Associations between FoPLs and change in (i) nutritional quality of food choices and (ii) ability to correctly rank the products by nutritional quality were assessed with logistic regression models adjusted for sociodemographic and lifestyle characteristics of participants, conducted overall and by country. FINDINGS: Compared with the Reference Intakes, the Nutri-Score (OR = 3.23[2.75-3.81]; p < 0.0001), followed by the Multiple Traffic Lights (OR = 1.68[1.42-1.98]; p < 0.0001), was the most effective FoPL in helping consumers identify the foods' nutritional quality, overall and in each of the 12 countries. Differences between FoPLs regarding food choice modifications were smaller, but the effect of the Nutri-Score seemed slightly higher in eliciting healthier food choices overall compared with the Reference Intakes, followed by the Warning symbols, the Multiple Traffic Lights and the Health Star Rating system. INTERPRETATION: In the context of FoPL harmonization in Europe, these findings from an online experiment provide insights into the Nutri-Score's effectiveness on European consumers.

Effectiveness of Different Front-of-Pack Nutrition Labels among Italian Consumers: Results from an Online Randomized Controlled Trial.

In Italy, discussions are currently ongoing to implement a front-of-pack nutrition label (FoPL) while a growing number of European countries are adopting the Nutri-Score. The effectiveness of the Nutri-Score among Italian consumers requires further investigation. This study compared five FoPLs among Italian participants (Health Star Rating system, multiple traffic lights, Nutri-Score, reference intakes, warning symbol) in terms of food choices and understanding of the labels by consumers. In 2019, 1032 Italian consumers completed an online survey in which they were asked to select one product they would likely purchase from a set of three foods with different nutrient profiles and then classify the products within the set according to their nutritional quality, first with no label and then with one of the five FoPLs on the pack. While no significant difference across labels was observed for food choices, the Nutri-Score demonstrated the highest overall performance in helping consumers to correctly rank the products according to their nutritional quality compared to the reference intakes (OR = 2.18 (1.50-3.17), p-value < 0.0001). Our results provide new insights on the effectiveness of the Nutri-Score, which would be a relevant tool to inform Italian consumers on the nutritional quality of food products.

Factors associated with formal volunteering among retirees.

The present study developed and tested a comprehensive multivariate model designed to assess the relative importance of various factors found or proposed in previous research to be associated with engagement in volunteering among 799 fully retired Australian older adults (62% female; mean age = 71.92 years (SD = 6.69)). Engagement in volunteering in the 12 months preceding the study and a range of sociodemographic, psychological, physical, social, and attitudinal variables were measured. Respondents' perceived personal responsibility to volunteer was found to be especially important in the tested model. This variable was directly associated with engagement in volunteering and acted as an important mediator between the following variables and volunteering engagement: personal growth, social connectedness, religious attendance, self-rated health, and depression. Efforts to increase volunteering engagement among older adults may therefore need to target perceptions of their responsibility to volunteer. Especially important focus areas for future strategies may include increasing social connectedness, facilitating personal growth, and improving self-rated health.

Bulgarian consumers' objective understanding of front-of-package nutrition labels: a comparative, randomized study.

BACKGROUND: Bulgaria continues to lag behind other EU Member States with respect to chronic disease morbidity and mortality prevention. METHODS: In line with efforts targeting the improvement of dietary practices, this comparative study assessed objective understanding of five different front-of-package labels (FOPL) (Reference Intakes, Multiple Traffic Lights, Warning label, Nutri-Score, and Health Star Rating) in a sample of 1010 Bulgarian adults. Objective understanding was assessed by comparing the results of two nutritional quality ranking tasks (with and without FOPL) in an online randomized experiment featuring three food categories (pizza, cakes, breakfast cereals). Multivariable ordinal logistic regression models within and across food categories were fit. RESULTS: Compared with the Reference Intakes group, participants randomized to Nutri-Score exhibited the largest improvement in product ranking ability across food categories (OR = 2.33; 95% CI: 1.55-3.51), followed by those randomized to Health Star Rating (OR = 1.99; 95% CI: 1.32-3.00). Nutri-Score also performed best within two (pizza and breakfast cereals) of the three food categories. The Multiple Traffic Lights and Warning label groups did not display any significant improvement in objective understanding either within or across food categories compared with the Reference Intakes group. CONCLUSION: Nutri-Score, which is a summary, interpretive, polychromatic FOPL, emerged as the most effective model in the Bulgarian context, with the potential to help consumers better understand the nutritional quality of food. The findings are of particular interest to public health policymakers in the region and across Europe, as the debate about an EU-wide FOPL model continues to gather momentum. TRIAL REGISTRATION: Registration number ACTRN12618001221246. Trial registered at the Australian New Zealand Clinical Trials Registry.

Implementation Outcomes Following Participation in a Large-Scale Healthy Workplace Program Conducted Across Multiple Worksites.

PURPOSE: To measure implementation outcomes of a freely available workplace health promotion program (Healthier Workplace Western Australia [HWWA]) that provides employees with services and supports to make changes in their workplaces. SETTING: Western Australian workplaces. SUBJECTS: Employees accessing HWWA services. INTERVENTION: A range of services (training sessions, tailored advice, grant schemes, online resources) were offered relating to nutrition, physical activity, smoking, alcohol consumption, and mental health. DESIGN/MEASURES: Of the 1627 individuals e-mailed 6 months after participation in HWWA, 345 (21%) individuals who recalled accessing one or more services completed a survey assessing the number and type of changes they had implemented and the perceived barriers to doing so. ANALYSIS: Negative binomial regressions and one-way analysis of variances assessed whether respondent characteristics or number of services used was associated with the number and types of changes made. A qualitative analysis of the perceived barriers was also conducted. RESULTS: The majority of respondents (86%) reported implementing one or more changes. Greater perceived responsibility/authority to make change (ß = .56, P < .01), perceived support from coworkers (ß = .23, P < .05), and number of HWWA services used (ß = .04, P < .05) were positive predictors of the number of changes made. Frequently reported barriers included cost/budget restrictions, lack of management support, and resistance from staff. CONCLUSION: The HWWA program facilitated implementation of various healthy workplace initiatives across the organizations represented in the evaluation.

Consumers' food choices, understanding and perceptions in response to different front-of-pack nutrition labelling systems in Belgium: results from an online experimental study.

BACKGROUND: Front-of-pack nutrition labels (FoPLs) are increasingly implemented by governments internationally to support consumers to make healthier food choices. Although the Nutri-Score FOPL has officially been implemented in Belgium since April 2019, no study has been conducted before its implementation to compare the effectiveness of different FOPLs. METHODS: The aim of this study was to compare food choices, objective understanding and perceptions of Belgian consumers in response to five different FOPLs, currently implemented in different countries internationally, namely the Health Star Ratings (HSR), the Multiple Traffic Lights (MTL), Nutri-Score, Guideline Daily Amounts (GDA), and Warning symbols. During the summer 2019, 1007 Belgian consumers were recruited and randomized to one of the five different FOPLs. Through an online questionnaire they were asked to choose one of three different foods within each of three categories (pizzas, cakes, breakfast cereals), as well as rank those same three foods according to nutritional quality, in the condition without as well as with FOPL. In addition, various questions were asked on their perceptions in relation to the FOPL they were exposed to. RESULTS: Perceptions of consumers were favorable for all FOPLs with no significant differences between the different FOPLs. There were no significant differences in food choices among the different FOPLs, but Nutri-Score performed best for ranking food products according to nutritional quality. CONCLUSIONS: While there were no significant differences among different FOPLs for food choices and perceptions, the Nutri-Score was the most effective FOPL in informing Belgian consumers of the nutritional quality of food products.

Compared to other front-of-pack nutrition labels, the Nutri-Score emerged as the most efficient to inform Swiss consumers on the nutritional quality of food products.

BACKGROUND: Switzerland, like other high-income countries, is facing a major public health challenge with the increasing burden of non-communicable diseases. Discussions are currently on-going in Switzerland regarding the implementation of a Front-of-Pack nutrition label (FoPL) as a public health measure to guide consumers towards healthier food choices, and the Nutri-Score represents an alternative supported by multiple actors. To date, no studies have investigated the performance of the Nutri-Score among Swiss consumers. This study aimed to compare the response of Swiss consumers to five FoPLs (Health Star Rating system, Multiple Traffic Lights, Nutri-Score, Reference Intakes and Warning symbol) in terms of perception and understanding of these labels and effects on food choices. METHODS: In 2019, 1,088 Swiss consumers were recruited and asked to select one product from among a set of three foods with different nutritional profiles and then classify the products within the sets according to their nutritional quality. Tasks were performed in situations without a label and then with one of the five FoPLs-depending on the group in which they were randomized-on the pack. Finally, participants were questioned on their perceptions regarding the label to which they were exposed. RESULTS: All FoPLs were favorably perceived, with marginal differences between FoPLs. The Nutri-Score demonstrated the highest percentage of improvement in food choices and the highest overall performance in helping consumers rank the products according to their nutritional quality. CONCLUSION: Overall, the Nutri-Score was the most efficient FoPL in informing Swiss consumers of the nutritional quality of food products, and as such could be a useful tool to improve food choices and reduce the burden of chronic diseases in Switzerland.

Enhancing the effectiveness of the Health Star Rating via presentation modifications.

OBJECTIVE: Research demonstrates the superiority of highly interpretive front-of-pack nutrition labels. The aim of this study was to assess the potential to enhance the Health Star Rating (HSR) by increasing its 'interpretiveness' through the addition of colour and the exclusion of the nutrient icons. METHODS: An online survey was administered to 1,033 Australian adults who were randomly allocated to one of four conditions: black and white (B&W) full HSR, colour full HSR, B&W star rating only, and colour star rating only. Each respondent viewed four packs of breakfast cereal of varying levels of healthiness as indicated by the displayed HSRs. Respondents nominated the product option they would prefer to buy and then the one they understood to be healthiest. RESULTS: Coloured HSR variations scored better than their B&W counterparts and the star-only versions scored better than the corresponding versions displaying nutrient icons. Overall, the coloured star-only HSR performed significantly better than the B&W full HSR for both choice and understanding. CONCLUSIONS: Increasing the interpretive nature of the HSR could enhance its effectiveness. Implications for public health: Policy makers should consider the evolution of the HSR towards a more interpretive presentation that includes colour and excludes the nutrient icons.
