Objective: The current study aimed to assess the nutritional quality of Australian secondary school canteen menus. Design: Stratified national samples of schools provided canteen menus in 2012–2013 and 2018, which were systematically assessed against a 'traffic light' classification system according to the National Healthy School Canteen Guidelines. Items were classified as green (healthiest and recommended to dominate canteen menus), amber (select carefully) or red (low nutritional quality, should not appear on canteen menus), and pricing and promotional strategies were recorded. Setting: Australia. Participants: Canteen menus from 244 secondary schools (2012–2013 n 148, 2018 n 96). Results: A total of 21 501 menu items were classified. Forty-nine percent of canteen menus contained at least 50 % green items; however, nearly all (98·5 %) offered at least one red item and therefore did not comply with national recommendations. Snacks and drinks had the least healthy profile of all product sectors, and a large proportion of schools supplied products typically of poor nutritional quality (meat pies and savoury pastries 91·8 %, sugary drinks 89·5 %, sweet baked goods 71·5 %, ice creams 64·1 % and potato chips 44·0 %). Red items were significantly cheaper than green items on average, and many schools promoted the purchase of red items on canteen menus (52·8 %). There were few differences between survey waves. Conclusions: There is considerable room for improvement in the nutritional quality of canteen menus in Australian secondary schools, including in the availability, pricing and promotion of healthier options. Additional resources and services to support implementation of national guidelines would be beneficial. [ABSTRACT FROM AUTHOR]

Objective: To explore parents' responses to sponsorship of children's sport by unhealthy food brands and two alternative pro-health sponsorship options.Design: Between-subjects online experiment with four sponsorship conditions: (i) non-food branding (control); (ii) unhealthy food branding; (iii) healthier food branding; (iv) public health nutrition campaign branding. Participants were shown a short video and a promotional flyer for a fictional junior sports programme, with sponsor content representing their assigned brand. Afterwards, participants were asked a series of questions assessing their brand awareness, brand attitudes and preference for food sponsor branded products.Setting: Australia.Participants: Australian parents (n 1331) of children aged 6-9 years.Results: Compared with the control condition, unhealthy food sponsorship promoted increased awareness, branded product preferences and favourable attitudes towards unhealthy food sponsor brands. Healthier food sponsorship promoted similar effects for healthier food sponsor brands, except there was no significant increase in positive attitudes towards these brands. Sponsorship by public health nutrition campaigns promoted more negative attitudes towards unhealthy food sponsor brands and increased preference for healthier food sponsor branded products. Overall, healthier food sponsors and public health campaign sponsors were perceived to have better programme-sponsor fit and to be more appropriate sponsors of children's sport than unhealthy food sponsors.Conclusions: Restrictions on unhealthy food sponsorship of children's sport are needed to prevent unhealthy food brands from exploiting junior sport sponsorship to enhance their appeal. Sponsorship of children's sport by healthier food brands or public health nutrition campaigns could help promote healthier food choices among parents. [ABSTRACT FROM AUTHOR]

Objective: To explore children’s responses to sponsorship of community junior sport by unhealthy food brands and investigate the utility of alternative, pro-health sponsorship options. Design: Between-subjects experiment, with four sponsorship conditions: A, non-food branding (control); B, unhealthy food branding; C, healthier food branding; D, obesity prevention campaign branding. Setting: Online experiment conducted in schools. Participants were shown a junior sports pack for their favourite sport that contained merchandise with branding representing their assigned sponsorship condition. Participants viewed and rated the sports pack, completed a distractor task, then completed questions assessing brand awareness, brand attitudes and preference for food sponsors’ products. Subjects: Students in grades 1 to 3 (aged 5–10 years; n 1124) from schools in metropolitan Melbourne, Australia. Results: Compared with the control condition, there were no significant effects of unhealthy food branding on awareness of, attitudes towards or preference for these brands. Exposure to healthier food branding prompted a significant increase in the proportion of children aware of these brands, but did not impact attitudes towards or preference for these brands. Exposure to either healthier food branding or obesity prevention campaign branding prompted a significant reduction in the proportion of children showing a preference for unhealthy food sponsor products. Conclusions: The sponsorship of children’s sport by healthier food brands may promote awareness of these brands and healthier sponsorship branding may reduce preferences for some unhealthy food products. Establishing and implementing healthy sponsor criteria in sports clubs could forge healthier sponsorship arrangements and help phase out unhealthy food and beverage sponsors. [ABSTRACT FROM AUTHOR]

ObjectiveTo identify predictors of increased adiposity for different measures of adiposity.DesignProspective cohort study, the Melbourne Collaborative Cohort Study (MCCS), with data at baseline (1990–1994) and wave 2 (2003–2007).SettingParticipants recruited from the community.SubjectsAustralian-born participants (n 5879) aged 40 to 69 years who were not current smokers and who were free from common chronic diseases at recruitment. At baseline and at wave 2, weight and waist circumference were measured; while demographic and lifestyle variables were obtained at baseline via structured interviews.ResultsParticipants who reported any recreational physical activity at baseline had lower weight and smaller waist circumference at wave 2 than those who did not, particularly for younger participants and for vigorous physical activity. Walking for leisure was not associated, and greater physical activity at work was associated, with greater adiposity measures at wave 2. A diet low in carbohydrates and fibre, but high in fat and protein, predicted greater weight and waist circumference at wave 2. Participants were less likely to have elevated weight or waist circumference at wave 2 if they consumed low to moderate amounts of alcohol.ConclusionsOur findings indicate that promoting vigorous physical activity, encouraging a diet high in carbohydrate and fibre but low in fat and protein, and limiting alcohol intake could be promising approaches for preventing obesity in middle-aged adults. Similar interventions should successfully address the management of both weight and waist circumference, as they were predicted by similar factors. [ABSTRACT FROM PUBLISHER]
