To examine demographic and behavioural correlates of high consumption of soft drinks (non-alcoholic sugar-sweetened carbonated drinks excluding energy drinks) among Australian adolescents and to ...explore the associations between high consumption and soft drink perceptions and accessibility.
Cross-sectional self-completion survey and height and weight measurements.
Australian secondary schools.
Students aged 12-17 years participating in the 2012-13 National Secondary Students' Diet and Activity (NaSSDA) survey (n 7835).
Overall, 14 % of students reported consuming four or more cups (≥1 litres) of soft drinks each week ('high soft drink consumers'). Demographic factors associated with high soft drink consumption were being male and having at least $AU 40 in weekly spending money. Behavioural factors associated with high soft drink consumption were low fruit intake, consuming energy drinks on a weekly basis, eating fast foods at least once weekly, eating snack foods ≥14 times/week, watching television for >2 h/d and sleeping for <8 h/school night. Students who perceived soft drinks to be usually available in their home, convenient to buy and good value for money were more likely to be high soft drink consumers, as were students who reported usually buying these drinks when making a beverage purchase from the school canteen/vending machine.
High soft drink consumption clusters with other unhealthy lifestyle behaviours among Australian secondary-school students. Interventions focused on reducing the availability of soft drinks (e.g. increased taxes, restricting their sale in schools) as well as improved education on their harms are needed to lower adolescents' soft drink intake.
There is growing evidence of the increased cancer risk associated with alcohol consumption, but this is not well understood by the general public. This study investigated the acceptability among ...drinkers of cancer warning statements for alcoholic beverages.
Six focus groups were conducted with Australian drinkers to develop a series of cancer-related warning statements for alcohol products. Eleven cancer warning statements and one general health warning statement were subsequently tested on 2,168 drinkers via an online survey. The statements varied by message frame (positive vs negative), cancer reference (general vs specific), and the way causality was communicated ('increases risk of cancer' vs 'can cause cancer').
Overall, responses to the cancer statements were neutral to favorable, indicating that they are unlikely to encounter high levels of negative reaction from the community if introduced on alcoholic beverages. Females, younger respondents, and those with higher levels of education generally found the statements to be more believable, convincing, and personally relevant. Positively framed messages, those referring to specific forms of cancer, and those using 'increases risk of cancer' performed better than negatively framed messages, those referring to cancer in general, and those using the term 'can cause cancer'.
Cancer warning statements on alcoholic beverages constitute a potential means of increasing awareness about the relationship between alcohol consumption and cancer risk.
The increasing reliance on grandparents as a source of childcare means that child dietary intake, child obesity, and child health may be increasingly influenced by grandparents' food provision. ...Although calls have been made for research that explores the role of grandparents in shaping children's eating behaviours, results of research assessing the types of foods provided by grandparents have been limited in focus to fruit and vegetables or energy-dense nutrient-poor foods. In addition, research assessing the determinants of food provision is lacking. Such information is important in identifying targets for education programs that aim to improve grandparents' food provision practices. Accordingly, the present study assessed the extent to which Australian grandparents are providing meals and snacks for their grandchildren, the types of foods and beverages being provided, and the determinants of provision. Grandparents providing regular childcare (i.e., ≥3 h every week) to at least one grandchild aged 3–14 years were recruited (n = 1076; 60% female; age = 65.07 years (SD = 6.68)). Results revealed that a majority of grandparents (82%) reported providing their grandchild with snacks. Nearly one-fifth (18%) of grandparents reported providing breakfast, lunch, dinner, and snacks. The provision of main meals occurred one to three times a week and snack provision occurred two to six times a week. Although grandparents generally provided a healthy food environment, practices were found to differ by the sociodemographic characteristics (sex, age, and socioeconomic status) of grandparent caregivers and by the sex and age of the grandchild in their care. Results suggest that grandparents should be considered crucial to efforts to increase healthy eating in children and address childhood obesity.
To examine demographic and behavioural correlates of frequent consumption of fast food among Australian secondary school students and explore the associations between fast food consumption and ...social/environmental factors.
Cross-sectional survey using a web-based self-report questionnaire.
Secondary schools across all Australian states and territories.
Students aged 12-17 years participating in the 2012-2013 National Secondary Students' Diet and Activity survey (n 8392).
Overall, 38 % of students surveyed reported consuming fast food at least weekly. Being male, residing in lower socio-economic areas and metropolitan locations, having more weekly spending money and working at a fast food outlet were all independently associated with consuming fast food once a week or more, as were several unhealthy eating (low vegetable intake and high sugary drink and snack food intake) and leisure (low physical activity and higher commercial television viewing) behaviours and short sleep duration. Frequent fast food consumption and measured weight status were unrelated. Students who agreed they go to fast food outlets with their family and friends were more likely to report consuming fast food at least weekly, as were those who usually 'upsize' their fast food meals and believe fast food is good value for money.
These results suggest that frequent fast food consumption clusters with other unhealthy behaviours. Policy and educational interventions that reach identified at-risk groups are needed to reduce adolescent fast food consumption at the population level. Policies placing restrictions on the portion sizes of fast food may also help adolescents limit their intake.
The consumption of vegetables and fruit during adolescence is crucial to ensuring adequate intake of the nutrients required to meet the rapid growth that characterises this developmental period. ...However, significant reductions in vegetable and fruit intake during adolescence have been observed making the promotion of consumption an important health promotion challenge. To monitor progress in this population segment toward meeting recommended intake levels and identifying at-risk groups, the present study assessed changes in Australian adolescents' vegetable and fruit consumption over time and identified the demographic factors associated with meeting recommendations. As individuals who are aware of their diet deficiencies are likely to be more receptive to healthy eating interventions, the present study also assessed adolescents' perceptions of the adequacy of their vegetable and fruit intake and identified the demographic factors associated with correctly perceiving fruit and vegetable intake to be inadequate. Two cross-sectional samples of Western Australian secondary school students aged 12–17 years were surveyed in 2009–2010 (n = 1501) and 2012–2013 (n = 1406). Only 14% of students at Wave 1 and 13% at Wave 2 met the recommended guidelines for vegetable intake while 68% and 71% met the guidelines for fruit intake. Females had significantly greater odds of failing to meet guidelines for vegetable intake than males. Only 50% of students correctly identified their vegetable and fruit intake to be inadequate. The observed very low levels of compliance with vegetable intake recommendations suggest that addressing deficiencies in vegetable consumption should be a primary focus of future nutrition interventions. Efforts should also be made to increase adolescents' perceptions of the inadequacy of their intake to optimise the effectiveness of schemes designed to improve vegetable and fruit consumption in this population segment.
For more than 20 years, the FOODcents adult nutrition education programme has been delivered to Western Australians. The aim of the programme is to provide disadvantaged individuals with the ...knowledge, skills and motivation to buy healthy foods on a limited budget. The present study evaluated whether the FOODcents curriculum and the way it is delivered are effective in improving participants' nutrition-related knowledge and behaviours.
Evaluation data were collected via in-session pre-post questionnaires and a post-course online questionnaire.
Western Australia.
Data were collected from participants attending just over one-half (54 %) of the FOODcents courses conducted over the two-year evaluation period. In total, 927 course participants provided usable data.
After exposure to the course, respondents demonstrated an improved ability to: (i) categorize foods according to the frequency with which they should be consumed and the proportion of the food budget that should be allocated to them; (ii) correctly interpret nutrition labels on food products; and (iii) appreciate the link between diet/obesity and a range of diseases. Improvements in the latter were especially pronounced among participants of low socio-economic status. In terms of behaviour change, significant improvements in fruit and vegetable consumption were reported, along with reductions in the consumption of fast food. Participants of low socio-economic status reported the greatest changes.
The results indicate that the FOODcents nutrition education programme improves participants' nutrition-related knowledge and behaviours.
Adolescence is a critical time for disengagement from physical activity making young people a priority group for interventions. To determine whether existing initiatives are working in this ...population segment and help inform future programs, the present study sought to (i) examine prevalences and trends in physical activity and screen-based recreation among Australian adolescents and (ii) identify the barriers to adolescents meeting recommended guidelines. Two cross-sectional representative samples of Western Australian secondary school students aged 12 to 17years were surveyed in 2009–2010 (n=1505) and 2012–2013 (n=1406). Around a quarter (24%) of boys and just 9% of girls reported engaging in the recommended 60min of physical activity per day in 2012–2013. A minority (13% of boys, 17% of girls) adhered to guidelines for time spent engaging in screen-based recreation (≤2h of electronic media use for entertainment). These findings were comparable to 2009–2010 prevalence levels. Multivariable logistic regression analyses conducted on data from the most recent wave found individual-level barriers to be significantly associated with lower odds of meeting physical activity guidelines in both boys (Adj. OR=0.52, 95% CI=0.38, 0.72) and girls (Adj. OR=0.41, 95% CI=0.25, 0.66). The consistently high proportion of adolescents not meeting physical activity recommendations over time suggests that current efforts to increase physical activity may be failing to have an impact on population-level trends in compliance. While initiatives to improve the built environment may reduce barriers at the environmental level, these initiatives risk having little impact on physical activity if individual level barriers remain unaddressed.
•Very few adolescents met physical activity and screen-based recreation guidelines.•Adherence to the guidelines remained consistently low over time.•Individual barriers were associated with lower odds of meeting activity guidelines.
► Adolescents are routinely exposed to food marketing via multiple channels. ► Increased exposure associated with adolescents’ food choices and eating behaviors. ► Tighter restrictions on food ...marketing are required across all types of media.
The present study examined associations between food marketing exposure and adolescents’ food choices and reported consumption of energy-dense and nutrient-poor (EDNP) foods. A cross-sectional survey of 12,188 Australian secondary students aged 12–17
years was conducted, using a web-based self-report questionnaire. Measures included students’ level of exposure to commercial television and non-broadcast types of food marketing, whether they had tried a new product or requested a product they had seen advertised, and their reported consumption of fast food, sugary drinks and sweet and salty snacks. Results indicated greater exposure to commercial television, print/transport/school food marketing and digital food marketing were all independently associated with students’ food choices. High commercial television viewers (>2
h/day) were more likely to report higher consumption of EDNP foods (ORs ranged from 1.31 for fast food to 1.91 for sweet snacks). Some associations between digital food marketing exposure and students’ eating behaviors were found; however, print/transport/school food marketing was only related to sweet snack consumption. These study results suggest that cumulative exposure to television food advertising and other food marketing sources are positively linked to adolescents’ food choices and eating behaviors. Policy changes to restrict food marketing to young people should include both television and non-broadcast media.
Nutrition interventions that target both fruits and vegetables are effective in increasing fruit consumption, but have been limited in their ability to improve vegetable intake. To address the low ...proportion of children meeting vegetable intake guidelines, approaches specifically targeting vegetables are needed. This paper reports on a mixed-method analysis of a 10-week vegetable promotion pilot project that aimed to increase vegetable intake as part of the existing Crunch&Sip in-class fruit and vegetable break program.
The intervention was designed to promote vegetable consumption through the implementation of vegetable-focused resources, including curriculum resources and parent education materials. Teachers completed pre- and end-of-intervention surveys. Process measures related to the use of resources and teachers' perceptions of barriers to implementation. The outcome evaluation included measures of children's vegetable consumption during Crunch&Sip breaks and teachers' attitudes and confidence relating to educating students about the benefits of consuming vegetables.
Twenty-one Western Australian primary schools already participating in the Crunch&Sip program participated in the pilot intervention and evaluation. Coverage included 35 primary school teachers representing 818 students aged 4–11 years.
The proportion of children bringing vegetables for Crunch&Sip more than doubled over the 10-week intervention (21% vs 46%; p < 0.001). Improvements were observed in teachers' perceived knowledge about the nutritional benefits of vegetables (p = 0.001) and confidence to educate students about the benefits of vegetable consumption (p = 0.028).
Preferentially promoting vegetable consumption as part of an existing school-based nutrition program may be an effective strategy to increase children's vegetable intake.
The Crunch&Sip programme is a school-based nutrition initiative designed to increase the fruit, vegetable and water intakes of primary-school children. In recognition of the notable deficits in ...children's vegetable consumption, the present study explored the receptivity of school staff to a realignment of the Crunch&Sip programme to feature a primary focus on vegetable consumption. This involved investigating school staff members' perceptions of relevant barriers, motivators and facilitators.
A multi-method approach was adopted that involved four focus groups and a survey (administered in paper and online formats) containing a mixture of open- and closed-ended items.
Western Australia.
Staff from Western Australian schools participated in the focus groups (n 37) and survey (n 620).
School staff were strongly supportive of modifying the Crunch&Sip programme to focus primarily on children's vegetable consumption and this was generally considered to be a feasible change to implement. Possible barriers identified included children's taste preferences and a perceived lack of parental support. Suggested strategies to overcome these barriers were education sessions for parents and children, teachers modelling vegetable consumption for their students and integrating vegetable-related topics into the school curriculum.
School staff are likely to support the introduction of school-based nutrition programmes that specifically encourage the consumption of vegetables. Potential barriers may be overcome through strategies to engage parents and children.
