This study aimed to develop and evaluate a multidimensional diet quality score for sustainable healthy diets (SUSDIET). Consensus from experts on procedures to establish an operational definition for a global sustainable healthy diet were used for the development of SUSDIET. Data on adults (≥19 years, n = 5000) from the Australian National Nutrition and Physical Activity Survey 2011-12 were used to evaluate SUSDIET. Mean scores of the SUSDIET were analysed according to participants characteristics. Regression models were used to assess the associations between SUSDIET and intake of nutrients and cardiometabolic health outcomes (indicators of adiposity and hypertension). We developed SUSDIET, a food-based diet quality score incorporating variety of plant foods (12 food groups), intake of animal products (5 food groups), and ultra-processed foods (1 food group). SUSDIET overall score ranges from 0 to 15, with a higher score indicating a more healthy and sustainable diet. Among Australian adults, SUSDIET overall score was 5.83 ± 0.03 (range 0.21–10.80), and was associated with a healthier nutrient profile and lower odds of obesity and abdominal obesity. SUSDIET will support research aiming to assess the impact of diets on both health and environmental sustainability outcomes among the general adult population and inform diet monitoring globally.</div></div>","PeriodicalId":242,"journal":{"name":"Appetite","volume":"216 ","pages":"Article 108270"},"PeriodicalIF":3.8,"publicationDate":"2025-08-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144861952","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

It has also been suggested that FRSA might foster critically conscious consumers and socially competent individuals, and support product development. Yet, these aspects were only partially evaluated in the studies reviewed.

The findings revealed that 72 % of households had adopted at least one coping strategy in the year prior to the survey. The likelihood of employing each strategy varied with the level of food insecurity experienced by the household. The Rasch model suggested that coping strategies can be represented along a unidimensional continuum of severity: less severe strategies are adopted earlier as food shortages appear, while more severe strategies appear only under more extreme conditions. In addition to food insecurity, socio-economic status and education level were also significant predictors of the use of several strategies. These results suggest that coping strategies and food insecurity indicators capture distinct yet interconnected aspects of economic challenges to access food.

Higher parental use of food to regulate emotions predicted fewer calories EAH. Child eating traits were not found to be predictive of EE in the absence of hunger. We conclude that EE is a behaviour performed by some toddlers, yet an emotional perturbation alone is not enough to elicit EE at this developmental stage.

Parents need evidence-based advice on specific feeding practices, such as distraction techniques and portioning, that can be used to reduce children's intake of high energy-dense snacks. This experimental laboratory study tested the effectiveness of these feeding practices.</p><p><strong>Methods: </strong>Parents and children (3-5 years; N = 129) who were identified as having an avid or typical eating profile were recruited and randomly allocated to one of three conditions. Following a standardised meal, children's energy intake (kcal) in the absence of hunger was assessed. While children had access to a snack buffet, parents were asked to use one of the following feeding practices: (1) Distract - using distraction techniques to delay children's snack intake; (2) Portion - allowing children to have snacks from pre-portioned pots; or (3) Control - allowing children to eat the type and number of snacks that their child wanted to.</p><p><strong>Results: </strong>Children in the distraction condition consumed significantly less energy from snacks (M = 54.44 kcal, SD = 73.30) compared to children in the portion (M = 103.89 kcal, SD = 91.33, p < .001) or control condition (M = 115.92 kcal, SD = 90.55, p < .001). Energy intake in the portion and control conditions was not significantly different (p > .05). Children with avid versus typical eating profiles did not differ significantly in energy intake (p > .05).</p><p><strong>Conclusion: </strong>Parental use of distraction techniques may be effective for reducing children's intake of high energy-dense snacks and could be recommended for use to support the development of children's healthy eating. Research to examine the effectiveness of distraction in real-world settings is now needed.</p>","PeriodicalId":242,"journal":{"name":"Appetite","volume":"216 ","pages":"108257"},"PeriodicalIF":3.8,"publicationDate":"2025-08-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144803036","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
