Background: To address concerns that healthy weight and lifestyle campaigns (HWLCs) could have unintended psychological or behavioral consequences, this study tested reactions to TV advertisements from two HWLCs--"LiveLighter"® (employs graphic health effects messaging) and "Swap It Don't Stop It" (employs animation and light-hearted messaging). Methods: An online between-subjects experiment tested reactions to one of five advertisements: "Toxic Fat"; "Sugary Drinks" (both from "LiveLighter"); "Become a Swapper"; "How to Swap It" (both from "Swap It"); and "HSBC Bank" (control) among 2,208 adults from Western Australia and Victoria, Australia. Responses assessed were cognitive and emotional reactions, behavioral intentions, internalized weight bias, antifat attitudes, self-esteem and body dissatisfaction. Results: The HWLC advertisements prompted favorable cognitive reactions and weak to neutral positive and negative emotional responses. HWLC advertisements promoted stronger intentions to engage in adaptive lifestyle behaviors compared with the control advertisement. Intention to engage in maladaptive behaviors (e.g., skipping meals) was low overall and did not differ by condition. Compared with the control condition, participants who saw "LiveLighter" "Sugary Drinks" showed weaker disagreement with antifat attitudes; however, mean antifat attitude scores were still at the low end of the scale. HWLC advertisements did not promote internalized weight bias, reduced self-esteem or body dissatisfaction compared with the control advertisement. Conclusions: Overall, HWLC advertisements performed favorably compared with the control advertisement and showed no clear evidence of adverse impacts. Findings suggest HWLC advertisements may not promote negative psychological and behavioral consequences and can continue to be used in obesity prevention efforts.

The LiveLighter® 2016 'Junk Food' campaign ran for 5 weeks in Western Australia (WA) and urged adults to reduce their junk food consumption to avoid weight gain and associated chronic disease. A cohort design assessed campaign impact on knowledge, beliefs and behaviour. Pre-campaign (n = 1501) and post-campaign (n = 737) telephone surveys of WA adults aged 25-49 were undertaken. A post-campaign-only sample (n = 501) controlled for pre-test effects. The campaign reached 57% of respondents and increased knowledge of the link between overweight and non-alcoholic fatty liver disease (78% cf. 87%; P < 0.01). Following campaign activity, respondents were more likely to avoid purchasing food from settings depicted in the advertisements (fast food outlets: 63% cf. 77%; service stations: 82% cf. 93%; vending machines: 87% cf. 96%; all P < 0.001), particularly among pre-campaign consumers of fast food and salty snacks ([less than or equal to]2 times/week). Weight-loss self-efficacy increased among adults with higher body weight and campaign exposure (89% cf. 97%; P < 0.01), and there was no increased endorsement of overweight stereotypes among the full sample. Support for fiscal disincentives and nutritional disclosure policies increased among healthy weight adults. LiveLighter® positively influenced knowledge, beliefs and behaviours, along with attitudes towards policies to encourage healthy eating, supporting LiveLighter® as an advocacy campaign.

: Objective: To examine active school travel trends and predictors among Australian secondary school students (aged 12–17) between 2009 and 2018. Methods: Three cross‐sectional surveys (2009‐10: N=13,790; 2012‐13: N=10,309; and 2018: N=9,102) using a web‐based self‐report questionnaire. Logistic regression was used to identify differences in active travel (to and/or from school every weekday) between survey years and predictors. Results: From 2009‐10 to 2012‐13 to 2018, active travel decreased from 33.6% to 32.3% to 29.5% among females, and from 37.4% to 36.6% to 32.6% among males. Distance, female sex and regional location were associated with a lower likelihood of active travel. Students with pocket money, those who spoke a language other than English at home, and Aboriginal and/or Torres Strait Islander students were more likely to actively travel. Conclusions: Between 2009‐10 and 2018, active school travel among secondary students in Australia declined. Several factors were found to be associated with active travel. Implications for public health: This is the first national study on active travel trends among secondary students in Australia. The recent decline requires action given the increasing prevalence of overweight and climate change., Physical activity has important health benefits for children, including reducing overweight/obesity and depression and increasing bone mineral density.[sup.1] Active school transport, or active travel between destinations by walking, cycling or [...]

Issue Addressed: The pervasive promotion of energy‐dense, nutrient‐poor food and drinks undermines efforts by adolescents and their parent/carers to maintain a nutritious diet during a crucial developmental period. This study examined the association between awareness of food and drink advertisements and adolescents' dietary behaviours and intake. Methods: A sample of Australian secondary students aged 12–17 years (N = 8763) self‐reported their awareness of food and drink advertisements across seven settings, whether they had tried a new product or asked a parent/carer to purchase a product they had seen advertised, and their consumption of various unhealthy food and drink types. Analyses used multilevel mixed‐effects generalised linear models adjusted for school‐level clustering, socio‐demographic factors and television viewing. Results: Students with higher advertising awareness were more likely to have tried a new product they had seen advertised (adjusted prevalence ratio [APR] = 1.62, 95% CI = 1.51–1.73, p <.001) and asked their parent/carer to buy an advertised product (APR = 1.62, 95% CI = 1.51–1.73, p <.001) at least once in the past month. As advertising awareness increased, so too did students' likelihood of reporting these dietary behaviours. A high unhealthy food intake was more commonly reported among students with higher advertising awareness (APR = 1.45, 95% CI = 1.32–1.58, p <.001), as was a high unhealthy drink intake (APR = 1.29, 95% CI = 1.18–1.42, p <.001). Conclusions: Australian adolescents are vulnerable to the persuasive effects of food and drink marketing. So What?: Greater restrictions on the way the food and drink industry can market their products to adolescents are needed to better support them in developing and maintaining positive dietary behaviours.

Background/Aims: Discretionary, energy‐dense, nutrient‐poor food and drinks are heavily marketed and readily available in retail settings frequented by adolescents. This study examines associations between food purchasing practices in various retail settings and dietary intake among Australian adolescents. Methods: Participants were students in years 8 to 11 (ages 12‐17 years) who completed the 2009‐10 (n = 13 790), 2012‐13 (n = 10 309) or 2018 (n = 9102) National Secondary Students' Diet and Activity (NaSSDA) cross‐sectional survey. Multistage stratified random sampling was used. An online survey completed at school assessed self‐reported frequency of food purchasing practices in various retail settings and consumption of discretionary food, sugary drinks, fruit and vegetables. Generalised linear regression models examined associations between food purchasing practices and dietary behaviour. Results: Relative to students who brought lunch from home, those who purchased lunch from school or nearby outlets reported higher intake of discretionary food and sugary drinks and lower fruit intake. Buying lunch from school was also associated with lower vegetable intake. Buying food or drinks on the school commute, outside school grounds during school hours, from supermarket checkouts, and using mobile phone apps were each associated with higher discretionary food and sugary drink intake (all P <.01). Conclusions: Purchasing food or drink in various retail settings is associated with higher intake of discretionary food and drink among Australian adolescents, and some purchasing practices appeared to displace fruit and vegetable intake. So What?: These findings highlight a need to improve the accessibility and promotion of healthier food and drink options in schools and other retail settings. [ABSTRACT FROM AUTHOR]

Issue addressed: The LiveLighter® healthy weight and lifestyle social marketing campaign, developed in Western Australia, employs graphic advertising to communicate negative health effects of overweight and motivate behaviour change. This study extends prior evidence of the effectiveness of the LiveLighter® campaign by evaluating its implementation in a new jurisdiction. Methods: A controlled cohort design was employed in intervention (Vic) and comparison states (SA), with and without campaign exposure. Population surveys conducted at baseline (BL) (n = 1000 each state), had 75% retention at follow‐up (FU) (Vic: n = 715; SA: n = 787). Results: Total campaign awareness was moderate (61.5%). Exposed respondents indicated the campaign was "believable" (91.0%), made a strong argument for reducing weight (87.3%), made them "stop and think" (70.1%), motivated action to reach/stay a healthy weight (59.1%) and was "relevant" (55.6%). The proportion of respondents indicating "toxic fat build up" was a health consequence of overweight increased significantly from BL to FU in Vic and to a lesser extent in SA (Vic:55.7% vs 75.9%; SA:58.1% vs 62.6%, interaction P <.001). The proportion indicating cancer is a health consequence of overweight increased significantly from BL to FU in Vic, but not in SA (Vic:77.1% vs 83.4%; SA:77.8% vs 78.1%, interaction P <.05). Conclusions: This study extends the evidence base for the LiveLighter® campaign. Sustained campaign activity with clear behavioural recommendations is required to translate improved knowledge into behaviour change. So what: Evidence‐based mass media campaigns can positively impact health behaviours to address the unsustainable increasing burdens of unhealthy weight, dietary risk and inadequate physical activity. A National Obesity Campaign is needed and LiveLighter® is a ready‐made, relevant Australian resource. [ABSTRACT FROM AUTHOR]
