RESUMO

BACKGROUND: Nutrition and health claims influence consumer purchasing. Claims include content claims, which refer to the amount of a nutrient contained in a product, and health claims, which refer to health benefits of foods or nutrients in a product. Products that display a health claim must meet the Nutrient Profiling Scoring Criterion (NPSC). The present study aimed to explore consumer perceptions of content claims used on food and beverage labelling and advertisements. METHODS: Semi-structured focus groups were conducted with Australian consumers. Analysis involved an inductive, reflexive approach to thematic analysis. RESULTS: Six focus groups involving 26 participants were conducted. Four main interconnected themes were generated: (1) complex factors influence food choice; (2) content claim scepticism; (3) the difference between content and health claims is unclear; and (4) the regulation of content claims is not common knowledge. Content claims were used, although generally viewed through a lens of scepticism and mistrust, and seen as a promotional tool for the food industry. Product complexity appeared to increase content claim use as a result of consumer uncertainty of the content of complex products, such as ultraprocessed foods. Most participants were aware that content and health claims were in some way regulated. Overall, they did not know further detail, including the relevant regulatory body. CONCLUSIONS: For content claims to support the consumer they need to be accurate and their use limited to healthier foods. This can be achieved by requiring products with content claims to meet NPSC thresholds, as required for products making health claims.

RESUMO

ISSUE ADDRESSED: The diets of Australian children, including their lunch boxes have a disproportionate amount of discretionary foods. Packaged snacks have marketing directed to both children and parents. METHODS: Packaged school lunch box snacks were identified on supermarket websites. Nutrition information and child-directed and parent-directed marketing on the package were analysed. The "healthiness" of products was analysed using the Health Star Rating (HSR) (presently on packaging in Australia), two criteria designed for assessing food suitable for marketing to children (the Australian Health Council and the World Health Organization Western Pacific region) and Chilean criteria (used for broad food regulation). RESULTS: The average HSR of the 135 products was 2.2% and 79% had a HSR <3.5. About 39% of products had child-directed marketing. Child-directed marketing would be removed from 89% sweet snacks, and 91% savoury snacks if products with a HSR <3.5 were not allowed to carry that marketing. This is less than the proportion not allowed using criteria from Chile (100%), World Health Organization Western Pacific Region (99%) and the Australian Health Council (93%). CONCLUSIONS: A policy that disallows marketing tactics on unhealthy food based on any of the criteria studied would remove most of both child-directed and parent-directed marketing on packaged lunch box snacks. SO WHAT?: Removing child-directed marketing from unhealthy products would help parents when shopping and contribute to addressing the high proportion of discretionary foods eaten by children at school. Child-directed marketing on packaging should be a part of comprehensive regulation to protect children from the marketing of unhealthy foods.

RESUMO

BACKGROUND: Pneumococcal conjugate vaccines (PCVs) have significantly reduced pneumococcal disease, but disease from non-PCV serotypes remains. The safety, tolerability, and immunogenicity of a 20-valent PCV (PCV20) were evaluated. METHODS: This pivotal phase 3, randomized, double-blind study enrolled adults into 3 age groups (≥60, 50-59, and 18-49 years) at US and Swedish sites. Participants were randomized to receive 1 PCV20 or 13-valent PCV (PCV13) dose. After 1 month, participants aged ≥60 years also received 1 dose of saline or 23-valent polysaccharide vaccine (PPSV23). Safety assessments included local reactions, systemic events, adverse events, serious adverse events, and newly diagnosed chronic medical conditions. Opsonophagocytic activity geometric mean titers 1 month after PCV20 were compared with 13 matched serotypes after PCV13 and 7 additional serotypes after PPSV23 in participants aged ≥60 years; noninferiority was declared if the lower bound of the 2-sided 95% confidence interval for the opsonophagocytic activity geometric mean titer ratio (ratio of PCV20/saline to PCV13/PPSV23 group) was >0.5. PCV20-elicited immune responses in younger participants were also bridged to those in 60-64-year-olds. RESULTS: The severity and frequency of prompted local reactions and systemic events were similar after PCV20 or PCV13; no safety concerns were identified. Primary immunogenicity objectives were met, with immune responses after PCV20 noninferior to 13 matched serotypes after PCV13 and to 6 additional PPSV23 serotypes in participants aged ≥60 years; serotype 8 missed the statistical noninferiority criterion. PCV20 induced robust responses to all 20 vaccine serotypes across age groups. CONCLUSIONS: PCV20 was safe and well tolerated, with immunogenicity comparable to that of PCV13 or PPSV23. PCV20 is anticipated to expand protection against pneumococcal disease in adults. CLINICAL TRIALS REGISTRATION: NCT03760146.

RESUMO

PURPOSE: This study examined the association of social contexts and food preparation location with the quality of meals and snacks (predominately from the five food groups (FFG) versus discretionary foods) in a sample of young Australian adults (18-30 years old) using wearable camera technology. METHODS: A sub-sample from the cross-sectional MYMeals study wore a wearable camera that captured images every 30 s for three consecutive days. Eating episodes from 133 participants (55% female) were classified across 4 domains: food quality (observed proportion of FFG and discretionary items), preparation location, social interaction, and screen use. Socio-economic status (SES) was assigned using residential postcode and gender self-reported. Associations of contexts and demographic factors with food quality stratified by meal type were determined using mixed binary logistic regression models. RESULTS: Of the 1840 eating episodes identified, 1775 were included in analysis (n = 8 preparation location and n = 57 food components that could not be identified were excluded). Food prepared at home was more likely to be from the FFG at lunch (OR = 4.8 95% CI 2.7-8.6), dinner (OR = 14.8 95% CI 7.6-28.6), and snacks (OR = 3.2 95% CI 2.2-4.8). Participants from higher SES areas were more likely to consume breakfasts (OR = 3.2 95% CI 1.4-7.4) and lunches (OR = 1.9 95% CI 1.0-3.7) predominately from the FFG. Females were more likely to consume lunches (OR = 2.0 95% CI 1.1-3.8) that was largely from the FFG. Social interaction and screen use were not associated with meal or snack quality. CONCLUSION: Wearable cameras have verified the importance of addressing meals and snacks prepared outside of home as an important contributor of discretionary food.

RESUMO

BACKGROUND: Pneumococcal conjugate vaccines (PCVs) have significantly decreased pneumococcal disease worldwide; however, expanding serotype coverage may further reduce disease burden. A 20-valent PCV (PCV20) containing capsular polysaccharide conjugates of serotypes present in the 13-valent PCV (PCV13) and 7 new serotypes (8, 10A, 11A, 12F, 15B, 22F, and 33F) is currently in development. This phase 2 study evaluated safety, tolerability, and immunogenicity of PCV20 in adults without prior pneumococcal vaccination. METHODS: In this randomized, active-controlled, double-blinded trial, 444 adults 60 through 64 years of age were randomized to receive either a single dose of PCV20 followed 1 month later by saline placebo or a single dose of PCV13 followed 1 month later by 23-valent polysaccharide vaccine. Local injection site reactions, select systemic symptoms, and adverse events (AEs) were recorded. Immunogenicity was assessed by measuring serotype-specific opsonophagocytic activity (OPA) titers before and approximately 1 month after each vaccination. RESULTS: Local reaction and systemic event rates were similar after vaccination with PCV20 or PCV13; no serious vaccine-related AEs were reported. In the PCV20 group, functional immune responses as measured by OPA were robust for all 20 serotypes included in the vaccine, with geometric mean fold rises from baseline ranging from 6.0 to 113.4. CONCLUSIONS: PCV20 was well tolerated in adults 60 to 64 years of age, with a safety profile consistent with historical experience of PCVs in this age group. Substantial OPA responses were elicited against all serotypes. Results demonstrate the potential for PCV20 to expand pneumococcal disease protection. CLINICAL TRIALS REGISTRATION: NCT03313037.

RESUMO

BACKGROUND: Globally children's diet quality is poor. Parents are primary gatekeepers to children's food intake; however, reaching and engaging parents in nutrition promotion can be challenging. With growth in internet and smartphone use, digital platforms provide potential to disseminate information rapidly to many people. The objectives of this review were to conduct a comprehensive and systematic evaluation of nutrition promotion via websites and apps supporting parents to influence children's nutrition, from three different perspectives: 1) current evidence base, 2) end user (parent) experience and 3) current commercial offerings. METHODS: Three systematic reviews were undertaken of (1) studies evaluating the effectiveness for digital platforms for improving nutrition in children and parents, (2) studies conducting user-testing of digital tools with parents, (3) websites and apps providing lunch-provision information to parents. Searches were conducted in five databases for reviews one and two, and systematic search of Google and App Store for review three. Randomised controlled trials, cohort and cross-sectional and qualitative studies (study two only) were included if published in English, from 2013, with the intervention targeted at parents and at least 50% of intervention content focused on nutrition. Search results were double screened, with data extracted into standardised spreadsheets and quality appraisal of included search results. RESULTS: Studies evaluating digital nutrition interventions targeting parents (n = 11) demonstrated effectiveness for improving nutrition outcomes, self-efficacy and knowledge. Six of the included randomised controlled trials reported digital interventions to be equal to, or better than comparison groups. User-testing studies (n = 9) identified that digital platforms should include both informative content and interactive features. Parents wanted evidence-based information from credible sources, practical tools, engaging content and connection with other users and health professionals. Websites targeting lunch provision (n = 15) were developed primarily by credible sources and included information-based content consistent with dietary guidelines and limited interactive features. Lunchbox apps (n = 6), developed mostly by commercial organisations, were more interactive but provided less credible information. CONCLUSIONS: Digital nutrition promotion interventions targeting parents can be effective for improving nutrition-related outcomes in children and parents. As demonstrated from the lunchbox context and user-testing with parents, they need to go beyond just providing information about positive dietary changes, to include the user-desired features supporting interactivity and personalisation.

RESUMO

OBJECTIVE: To determine whether there were changes in the prevalence or healthiness of products carrying claims post-implementation of Standard 1.2.7: Nutrition, Health and Related Claims in the Australia New Zealand Food Standards Code. DESIGN: Observational survey of claims on food packages in three categories: non-alcoholic beverages, breakfast cereals and cereal bars. Nutrient profiling was applied to products to determine their eligibility to carry health claims under Standard 1.2.7. The Standard came into effect in 2013. The proportion of products carrying claims and the proportion of those not meeting the nutrient profiling criteria were calculated. A comparative analysis was conducted to determine changes between 2011 and 2016. SETTING: Three large metropolitan stores from the three major supermarket chains in Sydney, Australia were surveyed in 2011 and 2016. PARTICIPANTS: All claims on all available products in 2016 (n 1737). Nutrition composition and ingredients were collected from the packaging. RESULTS: Overall in 2016, 76 % of products carried claims and there were 7367 claims identified in the three food categories. Of products in 2016 with health claims, 34 % did not meet nutrient profiling criteria. These may breach Standard 1.2.7. Comparison of 2011-2016 showed a significant increase in the number of products carrying claims (66 v. 76 %, P < 0·001). CONCLUSIONS: The proportion of products carrying claims that do not meet nutrient profiling and consumers' tendency to infer health benefits from nutrition content claims warrants the regulation of all claims using the nutrient profiling. This will ensure consumers are not misled by claims on unhealthy food products.

RESUMO

OBJECTIVE: A quarter of Australian children are overweight or obese. Research conducted in 2010 found that fast-food children's meals were energy-dense and nutrient-poor. Since then, menu labelling and self-regulation of marketing have been introduced in Australia. The present study aimed to: (i) investigate the nutrient composition of children's meals offered at fast-food chains; (ii) compare these with children's daily requirements and recommendations and the food industry's own criteria for healthier children's meals; and (iii) determine whether results have changed since last investigated in 2010. DESIGN: An audit of nutrition information for fast-food children's meals was conducted. Meals were compared with 30 % (recommended contribution for a meal) and 100 % of children's daily recommendations and requirements. A comparative analysis was conducted to determine if the proportion of meals that exceeded meal requirements and recommendations, and compliance with the food industry's own criteria, changed between 2010 and 2016. SETTING: Large Australian fast-food chains. PARTICIPANTS: All possible children's meal combinations. RESULTS: Overall, 289 children's meals were included. Most exceeded 30 % of daily recommendations and requirements for a 4-year-old's energy, saturated fat, sugars and Na. Results were also substantial for 8- and 13-year-olds, particularly for Na. When compared with mean energy and nutrient contents from 2010, there were minimal changes overall. CONCLUSIONS: Children's meals can provide excess energy, saturated fat, sugar and Na to children's diets. Systematic reformulation of energy, saturated fat, sugars and Na would improve the nutrient composition of the meals.

RESUMO

OBJECTIVE: The Food Standards Code regulates health claims on Australian food labels. General-level health claims highlight food-health relationships, e.g. 'contains calcium for strong bones'. Food companies making claims must notify Food Standards Australia New Zealand (FSANZ) and certify that a systematic literature review (SLR) substantiating the food-health relationship has been conducted. There is no pre- or post-notification assessment of the SLR, potentially enabling the food industry to make claims based on poor-quality research. The present study assessed the rigour of self-substantiation. DESIGN: Food-health relationships notified to FSANZ were monitored monthly between 2013 and 2017. These relationships were assessed by scoping published literature. Where evidence was equivocal/insufficient, the relevant government food regulatory agency was asked to investigate. If not investigated, or the response was unsatisfactory, the project team conducted an independent SLR which was provided to the government agency. SETTING: Australia.ParticipantsSelf-substantiated food-health relationships. RESULTS: There were sixty-seven relationships notified by thirty-eight food companies. Of these, thirty-three relationships (52 %) from twenty companies were deemed to have sufficient published evidence. Four were excluded as they originated in New Zealand. Three relationships were removed before investigations were initiated. The project initiated twenty-seven food-health relationship investigations. Another six relationships were withdrawn, and three relationships were awaiting government assessment. CONCLUSIONS: To ensure that SLR underpinning food-health relationships are rigorous and reduce regulatory enforcement burden, pre-market approval of food-health relationships should be introduced. This will increase consumer and public health confidence in the regulatory process and prevent potentially misleading general-level health claims on food labels.

RESUMO

OBJECTIVE: The present study examined the energy (kilojoule) content of Australian fast-food menu items over seven years, before and after introduction of menu board labelling, to determine the impact of the introduction of the legislation. DESIGN: Analysis of the median energy contents per serving and per 100g of fast-food menu items. Change in energy content of menu items across the years surveyed and differences in energy content of standard and limited-time only menu items were analysed. SETTING: Five of Australia's largest fast food chains: Hungry Jack's, KFC, McDonald's, Oporto and Red Rooster. SUBJECTS: All standard and limited-time only menu items available at each fast-food chain, collected annually for seven years, 2009-2015. RESULTS: Although some fast-food chains/menu item categories had significant increases in the energy contents of their menus at some time points during the 7-year period, overall there were no significant or systematic decreases in energy following the introduction of menu labelling (P=0·19 by +17 kJ/100 g, P=0·83 by +8 kJ/serving). Limited-time only items were significantly higher in median energy content per 100 g than standard menu items (+74 kJ/100 g, P=0·002). CONCLUSIONS: While reformulation across the entire Australian fast-food supply has the potential to positively influence population nutrient intake, the introduction of menu labelling legislation in New South Wales, Australia did not lead to reduced energy contents across the five fast-food chains. To encourage widespread reformulation by the fast-food industry and enhance the impact of labelling legislation, the government should work with industry to set targets for reformulation of nutrient content.

RESUMO

BACKGROUND: Community misconception of what causes cancer is an important consideration when devising communication strategies around cancer prevention, while those initiating social marketing campaigns must decide whether to target the general population or to tailor messages for different audiences. This paper investigates the relationships between demographic characteristics, identification of selected cancer risk factors, and associated protective behaviours, to inform audience segmentation for cancer prevention social marketing. METHODS: Data for this cross-sectional study (n = 3301) are derived from Cancer Council New South Wales' 2013 Cancer Prevention Survey. Descriptive statistics and logistic regression models were used to investigate the relationship between respondent demographic characteristics and identification of each of seven cancer risk factors; demographic characteristics and practice of the seven 'protective' behaviours associated with the seven cancer risk factors; and identification of cancer risk factors and practising the associated protective behaviours, controlling for demographic characteristics. RESULTS: More than 90% of respondents across demographic groups identified sun exposure and smoking cigarettes as moderate or large cancer risk factors. Around 80% identified passive smoking as a moderate/large risk factor, and 40-60% identified being overweight or obese, drinking alcohol, not eating enough vegetables and not eating enough fruit. Women and older respondents were more likely to identify most cancer risk factors as moderate/large, and to practise associated protective behaviours. Education was correlated with identification of smoking as a moderate/large cancer risk factor, and with four of the seven protective behaviours. Location (metropolitan/regional) and country of birth (Australia/other) were weak predictors of identification and of protective behaviours. Identification of a cancer risk factor as moderate/large was a significant predictor for five out of seven associated cancer-protective behaviours, controlling for demographic characteristics. CONCLUSIONS: These findings suggest a role for both audience segmentation and whole-of-population approaches in cancer-prevention social marketing campaigns. Targeted campaigns can address beliefs of younger people and men about cancer risk factors. Traditional population campaigns can enhance awareness of being overweight, alcohol consumption, and poor vegetable and fruit intake as cancer risk factors.

RESUMO

OBJECTIVE: To determine the extent that Australian fast-food websites contain nutrition content and health claims, and whether these claims are compliant with the new provisions of the Australia New Zealand Food Standards Code ('the Code'). DESIGN: Systematic content analysis of all web pages to identify nutrition content and health claims. Nutrition information panels were used to determine whether products with claims met Nutrient Profiling Scoring Criteria (NPSC) and qualifying criteria, and to compare them with the Code to determine compliance. SETTING: Australian websites of forty-four fast-food chains including meals, bakery, ice cream, beverage and salad chains. SUBJECTS: Any products marketed on the websites using health or nutrition content claims. RESULTS: Of the forty-four fast-food websites, twenty (45 %) had at least one claim. A total of 2094 claims were identified on 371 products, including 1515 nutrition content (72 %) and 579 health claims (28 %). Five fast-food products with health (5 %) and 157 products with nutrition content claims (43 %) did not meet the requirements of the Code to allow them to carry such claims. CONCLUSIONS: New provisions in the Code came into effect in January 2016 after a 3-year transition. Food regulatory agencies should review fast-food websites to ensure compliance with the qualifying criteria for nutrition content and health claim regulations. This would prevent consumers from viewing unhealthy foods as healthier choices. Healthy choices could be facilitated by applying NPSC to nutrition content claims. Fast-food chains should be educated on the requirements of the Code regarding claims.

RESUMO

Background: In response to rising childhood obesity rates, the Australian food industry implemented two initiatives in 2009 to reduce the marketing of unhealthy food to children. This study evaluated the efficacy of these initiatives on the rate of unhealthy food advertising to children on Australian television. Methods: The rates of food advertisements on three free-to-air commercial television channels and a youth-oriented digital channel in Sydney, Australia were analysed over 2 weekdays (16 h) and two weekend days (22 h). Advertisements were categorized according to the healthiness of foods advertised (non-core, core, miscellaneous) and signatory status to the food industry advertising initiatives. Results: Total food advertising rates for the three channels increased from 5.5/h in 2011 to 7.3/h in 2015, due to an increase of 0.8/h for both core and miscellaneous foods. The rate of non-core food advertisements in 2015 (3.1/h) was similar to 2011 (3.0/h). The youth-oriented channel had fewer total food advertisements (3.7/h versus 7.3/h) but similar fast-food advertisement rates (1.3/h versus 1.3/h). Conclusions: There was no change in the rate of unhealthy food advertising since 2011, suggesting minimal impact of the current food industry initiatives on reducing children's exposure to unhealthy food advertising.

RESUMO

BACKGROUND: Fruit and vegetable (F&V) consumption is below recommendations, and cost may be a barrier to meeting recommendations. Limited evidence exists on individual perceptions about the cost, actual spending and consumption of F&V. This study investigated perceptions and beliefs about cost of F&V and whether this is a barrier to higher consumption. METHODS: An online survey of Australian adults (n = 2474) measured F&V consumption; expenditure on F&V and food; and perceived barriers to consumption. Multivariable logistic regression examined associations between participants' responses about cost of F&V and demographic factors, and with actual consumption and expenditure on F&V. RESULTS: Cost was identified as a barrier for 29% of people not meeting recommended fruit servings and for 14% of people not meeting recommendations for vegetables. Cost was a more common barrier for those on lower incomes (fruit aOR 1.89; 95% CI 1.20-2.98 and vegetables aOR 2.94; 95% CI 1.97-4.39) and less common for older participants (fruit aOR 0.33; 95% CI 0.17-0.62 and vegetables aOR 0.31; 95% CI 0.18-0.52). There was no association between the perceived barriers and actual F&V spending. Twenty percent of participants said F&V were not affordable; 39% said cost made it difficult to buy F&V, and for 23% the cost of F&V meant they bought less than desired. CONCLUSIONS: A minority reported F&V were not affordable where they shopped and that cost was a barrier to higher consumption. However, it is apparent that young adults and those on low incomes eat less than they would like because of cost. Strategies that remove financial impediments to consumption are indicated for these population sub-groups.

RESUMO

BACKGROUND: In June 2014, the Australian government agreed to the voluntary implementation of an interpretive 'Health Star Rating' (HSR) front-of-pack labelling system for packaged foods. The aim of the system is to make it easier for consumers to compare the healthiness of products based on number of stars. With many Australians consuming fast food there is a strong rationale for extending the HSR system to include fast food items. OBJECTIVE: To examine the performance of the HSR system when applied to fast foods. DESIGN: Nutrient content data for fast food menu items were collected from the websites of 13 large Australian fast-food chains. The HSR was calculated for each menu item. Statistics describing HSR values for fast foods were calculated and compared to results for comparable packaged foods. RESULTS: Data for 1529 fast food products were compared to data for 3810 packaged food products across 16 of 17 fast food product categories. The mean HSR for the fast foods was 2.5 and ranged from 0.5 to 5.0 and corresponding values for the comparator packaged foods were 2.6 and 0.5 to 5.0. Visual inspection of the data showed broadly comparable distributions of HSR values across the fast food and the packaged food categories, although statistically significant differences were apparent for seven categories (all p < 0.04). In some cases these differences reflected the large sample size and the power to detect small variations across fast foods and packaged food, and in others it appeared to reflect primarily differences in the mix of product types within a category. CONCLUSIONS: These data support the idea that the HSR system could be extended to Australian fast foods. There are likely to be significant benefits to the community from the use of a single standardised signposting system for healthiness across all fresh, packaged and restaurant foods.

RESUMO

Although research has found that sexual activity declines with age, most of this literature examines people in long-term marriages. Little is known about the initiation of new sexual relationships in later life. In-depth interviews with 14 women aged 64 to 77 years were conducted to examine their personal and collective narratives regarding sexuality in later life. In contrast to common perceptions, none of the participants felt that aging had negatively impacted their own sexuality. For many, this was a time in their lives when they were experiencing renewed sexual desire and enjoyment. Even though sex might not have held the same priority as when they were younger, it held a place of importance in their romantic relationships. The discussion focuses on understanding women's sexual relationships and behaviors within the context of their cohort and lives.

RESUMO

OBJECTIVE: To determine whether the ratings from the Australian front-of-pack labelling scheme, Health Star Rating (HSR), and the ability to carry health claims using the Nutrient Profiling Scoring Criterion (NPSC) for core dairy products promote foods consistent with the Australian Dietary Guidelines. DESIGN: The Australian nutrient profiling model used for assessing eligibility for health claims was compared with the nutrient profiling model underpinning the HSR system to determine their agreement when assessing dairy products. Agreement between the extent to which products met nutrient profiling criteria and scored three stars or over using the HSR calculator was determined using Cohen's kappa tests. SETTING: The four largest supermarket chains in Sydney, Australia. SUBJECTS: All available products in the milk, hard cheese, soft cheese and yoghurt categories (n 1363) were surveyed in March-May 2014. Nutrition composition and ingredients lists were recorded for each product. RESULTS: There was 'good' agreement between NPSC and HSR overall (κ=0·78; 95 % CI 0·75, 0·81; P<0·001), for hard cheeses (κ=0·72; 95 % CI 0·65, 0·79; P<0·001) and yoghurt (κ=0·79; 95 % CI 0·73, 0·86; P<0·001). There was 'fair' agreement for milk (κ=0·33; 95 % CI 0·20, 0·45; P<0·001) and 'very good' agreement for soft cheese (κ=0·84; 95 % CI 0·75, 0·92; P<0·001). Generally, products tended to have HSR consistent with other products of a similar type within their categories. CONCLUSIONS: For dairy products, the HSR scheme largely aligned with the NPSC used for determining eligibility for health claims. Both systems appeared be consistent with the Australian Dietary Guidelines for dairy products, with lower-fat products rating higher.

RESUMO

This study examined the serving size and energy content per serving of Australian packaged snack foods and confectionery products. Nutrition Information Panel data for 23 sub-categories of packaged snack foods (n = 3481) were extracted from The George Institute for Global Health's 2013 branded food composition database. Variations in serving size and energy content per serving were examined. Energy contents per serving were compared to recommendations in the Australian Dietary Guidelines. Serving sizes varied within and between snack food categories. Mean energy content per serving varied from 320 kJ to 899 kJ. More energy per serving than the recommended 600 kJ was displayed by 22% (n = 539) of snack foods classified in the Australian Dietary Guidelines as discretionary foods. The recommendation for energy content per serving was exceeded in 60% (n = 635) of snack foods from the Five Food Groups. Only 37% (n = 377) of confectionery products displayed the industry-agreed serving size of 25 g. Energy content per serving of many packaged snack foods do not align with the Australian Dietary Guidelines and the industry agreed serving size has not been taken up widely within the confectionery category. Given the inconsistencies in serving sizes, featuring serving size in front-of-pack information may hinder the objective of a clear and simple nutrition message. Messaging to help consumers make healthier choices should consider the variation in serving sizes on packaged snack foods.

RESUMO

BACKGROUND: Australian and most international Dietary Guidelines recommend people consume more fruits and vegetables (F&V) to maintain a healthy weight and reduce chronic disease risk. Previous Australian and international surveys have shown sub-optimal consumption of F&V. OBJECTIVES: This study aimed to assess adults' F&V consumption, knowledge of recommended servings, readiness to change, barriers/enabling factors, so that this knowledge might be used for campaigns that support improved consumption. MATERIAL AND METHODS: An online survey of a representative sample of adults living in New South Wales, Australia (n = 2474) measuring self-reported F&V consumption; attitudes towards F&V consumption; stage of change for increasing F&V; barriers to consumption; and knowledge of cancer-health benefits. RESULTS: F&V consumption was below recommendations, with vegetable consumption notably low. Only 10% of participants ate at least five servings of vegetables/day (median intake was two daily servings), and 57% consumed two servings fruit/day. There was poor recognition that intake of vegetables was inadequate and this was a barrier to improving vegetable consumption; with preferences for other foods, habit and cost also important barriers. Key barriers to increasing fruit intake were habit, preferences for other foods, perishability, and cost. For vegetable consumption, 49% of participants were in the pre-contemplation stage of change, whereas for fruits 56% were in the action/maintenance stage. Sixty-four percent of respondents believed that eating F&V would protect against cancer, with 56% reporting they thought not eating enough F&V would cause cancer. IMPLICATIONS: Understanding what motivates and prevents people from consuming F&V is important for developing effective health promotion programs. Similar to previous surveys, there has been little shift in F&V consumption. Social marketing campaigns have been shown to improve health-related behaviours, and this study may assist in identifying audience segmentation for better targeted campaigns.

RESUMO

BACKGROUND: Persons with human immunodeficiency virus (HIV) infection are at increased risk of pneumococcal disease. We evaluated the safety and immunogenicity of 13-valent pneumococcal conjugate vaccine (PCV13) in this population. METHODS: HIV-infected persons ≥ 18 years of age who were previously vaccinated with ≥ 1 dose of 23-valent pneumococcal polysaccharide vaccine (PPSV23) and had CD4 cell counts ≥ 200 cells/mm(3) and HIV viral loads <50 000 copies/mL were enrolled in this 3-dose PCV13 open-label study. RESULTS: A total of 329 subjects received ≥ 1 dose, and 279 received 3 doses administered at 6-month intervals. Increases in anticapsular polysaccharide immunoglobulin G concentrations and opsonophagocytic antibody titers were demonstrated 1 month after each of the 3 doses of PCV13. Antibody levels were generally similar after each dose. The responses were similar whether subjects had previously received 1 or ≥ 2 doses of PPSV23. Pain at the injection-site was the most common local reaction. Severe injection site or systemic events were uncommon. CONCLUSIONS: Vaccination with PCV13 induces anticapsular immunoglobulin G and opsonophagocytic antibody responses in HIV-infected adults with prior PPSV23 vaccination and CD4 cell counts ≥ 200 cells/mm(3). The observations support the use of PCV13 in this population. CLINICAL TRIALS REGISTRATION: NCT00963235.
