RESUMEN

INTRODUCTION: Roll-your-own (RYO) tobacco is a popular choice in Australia, with some people who smoke finding these products more attractive than factory-made cigarettes (FMC). Differences in visual and tactile properties and in the feel and taste of the smoke may contribute to this attractiveness. These differences may be driven by variation in tobacco constituents and wrapping paper permeability. However, to date, there has been no comparison of RYO and FMC products on the Australian market. AIMS AND METHODS: Chemical constituents, pH, flavorants, and paper permeability were compared in unburned RYO tobacco and tobacco from FMC. RYO and FMC products from matched brands were compared, as were products from the most popular FMC and RYO brands on the Australian market in 2018. RESULTS: RYO tobacco had higher moisture and humectant content (glycerol and propylene glycol) than FMC tobacco. RYO tobacco also had higher amounts of total and reducing sugars and lower nicotine when comparing the most popular brands. RYO papers were less permeable than FMC papers. Both RYO and FMC tobacco contained many chemicals identified as flavorants, including fourteen with known potential health risks. For most measured constituents and flavorants, RYO tobaccos had more in common with other RYO than FMC, with the commonalities remaining even when matched brands were compared. CONCLUSIONS: Higher levels of moisture, humectants, and sugars in Australian RYO tobacco compared to FMC may be increasing attractiveness of RYO by reducing the harsh taste of the smoke and increasing the moist feel of the tobacco. IMPLICATIONS: While price is the main factor driving the use of RYO tobacco, some people who smoke find these products more attractive. This study has shown that Australian RYO tobacco contains higher amounts of glycerol, propylene glycol, and sugars than FMC. These chemicals may be improving the taste of the tobacco, as well as creating a moist feel that is falsely perceived as indicating that the tobacco is "fresh" and "less chemically." Ironically, it may be that higher amounts of some added chemicals in RYO contribute to false perceptions of a more natural and less harmful product.

RESUMEN

AIMS: To investigate whether 'low sugar' and related claims influence consumers' perceptions of the healthiness or other attributes of alcoholic drinks, promote greater consumption or impact diet and activity behaviour intentions. METHOD: N = 501 Australian women aged 18-35 viewed and rated six images of alcoholic drinks in a randomized online experiment with a 2 (claim: low sugar claim, no claim control) × 2 (drink type: cider, ready-to-drink spirits) between-subjects design. RESULTS: Participants who viewed drinks with low sugar claims rated them as healthier, less harmful to health, lower in sugar and kilojoules, and more suitable for weight management and a healthy diet than participants who viewed identical drinks with no claim (P < 0.001-P = 0.002). Drinks with low sugar claims were also perceived as being lower in alcohol (P < 0.001) despite being of equivalent alcohol content. There were no significant differences in anticipated social approval associated with consumption or in hypothetical intended consumption of the drinks, but participants who viewed drinks with low sugar claims were less likely to indicate they would compensate for consumption of the drink by modifying food intake or physical activity (P = 0.01). CONCLUSIONS: Low sugar and related claims on alcoholic drinks can generate a health halo: consumers generalise from a specific favourable attribute (low sugar) to misperceive other favourable health- and nutrition-related attributes, including lower alcohol content. Findings support calls to reconsider the permissibility of low sugar claims on alcoholic drinks as they may mislead consumers.

RESUMEN

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.

RESUMEN

Mass media campaigns can change attitudes and behaviours to improve population health. However, a key challenge is achieving share of voice in a complex and cluttered media environment. The aim of this study was to compare advertising expenditure on public health campaigns for obesity prevention (and related healthy eating and physical activity campaigns) with competing commercial categories of (a) sugary drinks, (b) artificially sweetened drinks and (c) diet/weight loss products and programmes. These commercial products may either undermine or dilute public health messages by directly contributing to poor health or confusing the public about the best ways to sustain a healthy lifestyle. Monthly estimates of advertising expenditure in Australian media (television, outdoor, cinema, radio, newspapers, magazines and digital) were obtained from Nielsen Media for 2016-18. Eligible public health advertising expenditure for the entire period (total AUD$27M) was vastly outweighed by the commercial categories of sugary drinks (AUD$129M) and diet/weight loss products and services (AUD$122M). Artificially sweetened drinks accounted for an additional AUD$23M of expenditure. These results highlight the need to rebalance the ratio of advertising to support public health in Australia through increased funding for obesity prevention and related campaigns, and critically, through government regulation to limit competing commercial advertising.

RESUMEN

Portion size impacts on the amount of energy consumed during a meal. However, research findings on participant characteristics that moderate the effect of portion size on energy intake are mixed. Using data pooled across three randomized control trials, we examined the impact of reducing meal portion size on meal energy intake in 111 adult participants varying in sex (55 M, 56 F), body weight (BMI range = 19-42) and a broad range of participant characteristics, including usual portion size, restrained, emotional and external eating, satiety responsiveness, plate clearing tendencies, concerns about wasting food and self-control. In each trial, a repeated-measures design was used and participants consumed three ad-libitum lunchtime meals differing in portion size; large-normal portion size condition (100%) vs. small-normal portion size condition (~ 75%) vs. smaller than normal portion size condition (~ 50%). In mixed ANOVAs, we did not find convincing evidence that any participant characteristic reliably moderated the impact that reducing portion size had on energy intake. For the majority of participants energy intake decreased when portion size was reduced and it was more common for participants to consistently reduce their energy intake than consume a similar amount when portion size was reduced. We also found little evidence that a sub-group of participants existed whose energy intake was consistently resistant to portion size reductions. Portion size may be a universal driver of energy intake, as reducing meal portion size appears to decrease meal energy intake among most people. Food portion downsizing may therefore be an equitable intervention approach to reducing population level energy intake.

RESUMEN

External influences on eating behaviour, such as portion size, have been reliably shown to influence food intake in the laboratory. However, little research has examined whether laboratory settings under or overestimate the effect that external influences have on food intake compared to when studied in the real-world. In Study 1, 60 participants (mean age = 32 years) were randomized to consume a large (200 g) or small (100 g) portion of popcorn under controlled laboratory conditions and during a separate session in their home. Results showed that the effect of portion size on food intake was larger at home (d = 0.97) than in the laboratory (d = 0.56). Furthermore, participants reported feeling more relaxed eating at home compared to the laboratory. In Study 2, we examined whether comparable results were observed in a semi-naturalistic laboratory designed to resemble a home setting. 59 participants (mean age = 28 years) completed the same procedure as Study 1 in a standard and a semi-naturalistic laboratory setting. Although participants reported having higher levels of private self-awareness in the standard laboratory, the effect that portion size had on food intake did not differ between the standard laboratory (d = 0.50) and the semi-naturalistic laboratory (d = 0.49). The impact that external influences on eating, such as portion size, have on food intake in the real-world may be underestimated when studied under laboratory conditions.

RESUMEN

BACKGROUND: Smaller portions may help to reduce energy intake. However, there may be a limit to the magnitude of the portion size reduction that can be made before consumers respond by increasing intake of other food immediately or at later meals. We tested the theoretical prediction that reductions to portion size would result in a significant reduction to daily energy intake when the resulting portion was visually perceived as 'normal' in size, but that a reduction resulting in a 'smaller than normal' portion size would cause immediate or later additional eating. METHODS: Over three 5-day periods, daily energy intake was measured in a controlled laboratory study using a randomized crossover design (N = 30). The served portion size of the main meal component of lunch and dinner was manipulated in three conditions: 'large-normal' (747 kcal), 'small-normal' (543 kcal), and 'smaller than normal' (339 kcal). Perceived 'normality' of portion sizes was determined by two pilot studies. Ad libitum daily energy intake from all meals and snacks was measured. RESULTS: Daily energy intake in the 'large-normal' condition was 2543 kcals. Daily energy intake was significantly lower in the 'small-normal' portion size condition (mean difference - 95 kcal/d, 95% CI [- 184, - 6], p = .04); and was also significantly lower in the 'smaller than normal' than the 'small-normal' condition (mean difference - 210 kcal/d, 95% CI [- 309, - 111], p < .001). Contrary to predictions, there was no evidence that the degree of additional food consumption observed was greater when portions were reduced past the point of appearing normal in size. CONCLUSIONS: Reductions to the portion size of main-meal foods resulted in significant decreases in daily energy intake. Additional food consumption did not offset this effect, even when portions were reduced to the point that they were no longer perceived as being normal in size.

RESUMEN

Skin cancer presents a significant public health burden in Australia. The present study aimed to supplement population-based estimates of sun protection behaviour by examining setting-specific trends in directly observed sun protection in public outdoor leisure settings. Repeated cross-sectional observational surveys of adolescents and adults were conducted on summer weekends between 11 am and 3 pm from 1992 to 2002, 2006 to 2012, and 2018 to 2019 (N = 44,979) at pools/beaches and parks/gardens within 25 km of the centre of Melbourne, Victoria. The primary outcome was a binary index representing individuals having above or below the median level of body surface covered by hat, shirt, and leg garments in each setting type. The prevalence of above-median body coverage increased between 1992 and 2002 in both settings. At pools/beaches, a slight decline in above-median body coverage between 2006 and 2019 in males and females (adjusted odds ratio, AOR = 0.96 [0.94, 0.97]; 0.94 [0.93, 0.95]) appeared to be driven by a decline in leg coverage, while arm coverage, hat, sunglasses, and shade use remained stable. At parks/gardens, a decline in above-median body coverage between 2006 and 2019 (AOR = 0.90 [0.89, 0.91]; 0.94 [0.93, 0.95]) was accompanied by small declines across other protective behaviours that varied between males and females. Patterns in protective behaviours observed in outdoor leisure settings may reflect the changing composition of individuals choosing to remain outdoors during peak UV times and highlight the importance of continued promotion and monitoring of the use of multiple measures to protect against UV damage in Australia.

RESUMEN

Reducing food portion size could reduce energy intake. However, it is unclear at what point consumers respond to reductions by increasing intake of other foods. We predicted that a change in served portion size would only result in significant additional eating within the same meal if the resulting portion size was no longer visually perceived as 'normal'. Participants in two crossover experiments (Study 1: n 45; Study 2: n 37; adults, 51 % female) were served different-sized lunchtime portions on three occasions that were perceived by a previous sample of participants as 'large-normal', 'small-normal' and 'smaller than normal', respectively. Participants were able to serve themselves additional helpings of the same food (Study 1) or dessert items (Study 2). In Study 1 there was a small but significant increase in additional intake when participants were served the 'smaller than normal' compared with the 'small-normal' portion (m difference = 161 kJ, P = 0·002, d = 0·35), but there was no significant difference between the 'small-normal' and 'large-normal' conditions (m difference = 88 kJ, P = 0·08, d = 0·24). A similar pattern was observed in Study 2 (m difference = 149 kJ, P = 0·06, d = 0·18; m difference = 83 kJ, P = 0·26, d = 0·10). However, smaller portion sizes were each associated with a significant reduction in total meal intake. The findings provide preliminary evidence that reductions that result in portions appearing 'normal' in size may limit additional eating, but confirmatory research is needed.

RESUMEN

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.

RESUMEN

BACKGROUND: Eating out is now common and food served out of the home is often of low nutritional quality. Kilocalorie (kcal) labelling of food and drink products sold in restaurant chains in the US is now mandatory, although in store kcal labelling practices among major UK restaurant and takeaway chains have not been examined. METHODS: During August 2018, we contacted, visited the website and/or retail outlets of major eating out and takeaway food chains in the UK, including full-service and fast-food restaurants, cafes and coffee shops, some of which had previously made a voluntary pledge to provide kcal labelling. We examined the proportion of chains providing kcal information to customers at point of choice in store and the extent to which kcal information provision adhered to labelling recommendations. We also examined the proportion of chains that did not have point of choice kcal labelling but were able to provide kcal information on request. The study protocol was pre-registered on the Open Science Framework. RESULTS: Of the 104 eligible chains, only a small minority (18 chains, 17%) provided in store kcal labelling. Of those that did, provision of kcal information tended not to adhere to recommended labelling practices. Of the 16 eligible chains that had previously committed to a voluntary public health pledge to provide point of choice kcal labelling, labelling did not meet recommendations and 4 (25%) did not provide kcal labelling. Of the 86 chains that did not provide kcal labelling in store, kcal information was available on request from 43 (50%) chains. CONCLUSIONS: It is rare for eating out and takeaway chains in the UK to provide point of choice kcal labelling and when labelling is provided it does not adhere to recommended labelling practices. Chains that previously volunteered to provide kcal labelling as part of an industry and public health partnership do so inadequately. Voluntary policies have not resulted in adequate kcal labelling in the UK eating out of home sector.

RESUMEN

Research conducted in controlled laboratory settings plays an important role in understanding human eating behaviour. However, participant characteristics may affect motivation to participate in laboratory eating behaviour research and result in self-selection biases. First-year psychology students (n = 207, 90.8% female, m age = 18.8, m BMI = 21.9) were led to believe that they were choosing between enrolling in one of two laboratory-based studies: an 'advertising' study, or an 'advertising and food' study; the latter specified that participants would consume food and answer questions about their eating behaviour. Participants subsequently reported demographic information and completed a series of questionnaires assessing psychological characteristics hypothesised to predict self-selection in laboratory eating studies. The majority of participants preferred to participate in a study unrelated to eating over an eating-related study (70.5%, χ2 (1) = 34.90, p < .001). Participants choosing the eating-related study over the non-eating study had higher self-reported external eating tendencies and positive preoccupations with food, lower negative preoccupations with food and social appearance anxiety. Participants choosing the eating related study were also more likely to be male than female, although the number of males in the study was small (n = 19) and this finding should therefore be interpreted with caution. The present study provides some evidence that in university based samples of participants there are likely self-selection biases in laboratory-based eating behaviour studies and researchers may benefit from considering the potential influence of self-selection biases when conducting eating behaviour research.

RESUMEN

Demand characteristics are thought to undermine the validity of psychological research, but the extent to which participant awareness of study hypotheses affects laboratory-measured eating behaviour studies has received limited attention. Participants (N = 84) attended two laboratory sessions in which food intake was measured. In session 1 baseline food intake was measured. In session 2 participants were allocated to either a 'hypothesis aware' or 'hypothesis unaware' condition. Participants were led to believe in the 'hypothesis aware' condition that they were expected to increase their food intake in session 2 relative to session 1. Participants in the 'hypothesis unaware' condition were not provided with hypothesis information. Contrary to our pre-registered predictions, the experimental manipulation of hypothesis awareness did not affect session 2 food intake. However, the manipulation was less effective than anticipated as some participants did not appear to believe the hypothesis information provided. Post-hoc exploratory analyses revealed that participants who believed the study hypothesis was that their food intake would increase in session 2 ate more in session 2 than participants who did not believe this was the study hypothesis. Further confirmatory research is required to understand the causal effect that participant awareness of study hypotheses has on laboratory measured eating behaviour.

RESUMEN

Because overconsumption of food contributes to ill health, understanding what affects how much people eat is of importance. The 'bogus' taste test is a measure widely used in eating behaviour research to identify factors that may have a causal effect on food intake. However, there has been no examination of the validity of the bogus taste test as a measure of food intake. We conducted a participant level analysis of 31 published laboratory studies that used the taste test to measure food intake. We assessed whether the taste test was sensitive to experimental manipulations hypothesized to increase or decrease food intake. We examined construct validity by testing whether participant sex, hunger and liking of taste test food were associated with the amount of food consumed in the taste test. In addition, we also examined whether BMI (body mass index), trait measures of dietary restraint and over-eating in response to palatable food cues were associated with food consumption. Results indicated that the taste test was sensitive to experimental manipulations hypothesized to increase or decrease food intake. Factors that were reliably associated with increased consumption during the taste test were being male, have a higher baseline hunger, liking of the taste test food and a greater tendency to overeat in response to palatable food cues, whereas trait dietary restraint and BMI were not. These results indicate that the bogus taste test is likely to be a valid measure of food intake and can be used to identify factors that have a causal effect on food intake.

RESUMEN

The current study used a modified implicit association test (IAT) to change implicit evaluations of unhealthy snack food and tested its effects on subsequent consumption. Furthermore, we investigated whether these effects were moderated by inhibitory self-control. A sample of 148 women (17-25 years) motivated to manage weight through healthy eating completed an IAT intervention, and pre- and post-intervention IATs assessing implicit evaluations of unhealthy food. The intervention IAT trained participants to pair unhealthy food stimuli with either positive or negative stimuli. A task disguised as a taste-test was used to assess consumption of unhealthy snack foods. Inhibitory self-control was measured using a self-report scale. As predicted, the implicit evaluation of unhealthy food became more negative from pre- to post-training among participants in the food negative pairing condition; however, there was no corresponding change in the food positive pairing condition. The effect of the training on snack consumption was moderated by inhibitory self-control with only participants low in inhibitory self-control having lower snack intake following the food negative training. This finding is consistent with dual-process models of behaviour which predict that self-control capacity renders impulses less influential on behaviour. Furthermore, it suggests that an intervention that retrains implicit food evaluations could be effective at reducing unhealthy eating, particularly among those with low inhibitory self-control.

RESUMEN

OBJECTIVE: Treatment beliefs and preferences for psychological therapies were investigated in 80 overweight individuals trying to manage their weight. METHOD: Participants read 4 therapy descriptions: cognitive behavioral therapy (CBT), behavior therapy (BT), cognitive therapy (CT), and acceptance and commitment therapy (ACT). They ranked the treatments in order of preference, explained the reason for their preferred choice, and reported their beliefs about each approach. RESULTS: Individual CBT (43.42%) and BT (31.58%), delivered face-to-face or technologically, were the most preferred treatment options, while ACT (17.12%) and CT (7.89%) were the least preferred. The main reasons cited among those who chose CBT and BT were perceived comprehensiveness and the practical nature of the approach, respectively. Treatment beliefs were strongly predicted by psychological need satisfaction as well as perceived ease and effort. CONCLUSIONS: Further research should ascertain the stability of treatment beliefs and the efficacy of modifying the treatment context to meet individual needs.

RESUMEN

OBJECTIVE: Some claims on alcohol labels highlight virtuous aspects of brands or products, including in health-, eco-, and cause-oriented domains (including charity partnerships, or ethical or humanitarian certifications). This virtue marketing may create a 'halo' whereby consumers generalise from specific attributes to a more favourable overall appraisal of the product, brand, or even alcohol or the alcohol industry in general. This study aims to describe the prevalence of and trends over time in virtue marketing on the packaging of new alcohol (including lower and zero alcohol) products on the Australian market. METHOD: Records of N=4,024 new alcohol products released in Australia between 2013 and 2023 were extracted from Mintel Global New Products Database. Health-, eco-, and cause-oriented claims on packaging were summarised across product types and time, and co-occurrence between claims was assessed. RESULTS: Virtue marketing appeared on 36.5% of new alcohol products, of which health-oriented claims were most common (32.5%), followed by eco- (6.3%) and cause-oriented claims (2.0%). The prevalence of each claim category and virtue marketing overall significantly increased over time (each p<.001) and varied by product type. New alcohol products displayed as many as eight different types of claims and all claims tended to co-occur with at least two others. CONCLUSIONS: Virtue marketing is prevalent on new alcohol products in Australia and has recently increased. While product packaging can provide useful consumer information, health-, eco-, and cause-oriented claims may exploit consumers' motivation to make healthy, sustainable, and socially responsible choices despite alcohol being detrimental in these areas.

RESUMEN

BACKGROUND AND AIMS: A health warning label (HWL) cautioning about the link between alcohol and cancer may be able to communicate alcohol risks to consumers and potentially counter health-oriented nutrition advertising on ready-to-drink alcoholic beverages. This study aimed to examine the independent and combined effects of nutrient content claims (e.g. 0 g sugar) and a HWL on perceived product characteristics and intentions to consume, and whether these effects differed by gender and age. DESIGN: A between-subjects randomized experiment. Participants were randomized to view one of six experimental label conditions: nutrient content claims plus nutrition declaration (NCC + ND), ND only, NCC + ND + HWL, ND + HWL, HWL only and no NCC, ND or HWL, all on a ready-to-drink (RTD) vodka-based soda container. SETTING AND PARTICIPANTS: Alcohol consumers (n = 5063; 52% women) in Canada aged 18-64 recruited through a national online panel. MEASUREMENTS: Participants completed ratings of perceived product characteristics, perceived product health risks, and intentions to try, buy, binge and drink the product. FINDINGS: Compared with the reference condition NCC + ND (current policy scenario in Canada), the other five experimental label conditions were associated with lower ratings for perceiving the product as healthy. All experimental conditions with a HWL were associated with lower product appeal, higher risk perceptions and reduced intentions to try, buy and binge. The experimental condition with a HWL only was associated with intentions to consume fewer cans in the next 7 days (ß = -0.72, 95% confidence interval [CI] = -1.37,-0.08) versus the reference. Few interactions were observed, suggesting that label effects on outcomes were similar by gender and age. CONCLUSIONS: Health warning labels on alcohol packaging appear to be associated with lower product appeal, higher perceived health risks and reduced consumption intentions, even in the presence of nutrient content claims.
