RESUMEN

Objective: Analyse the breakfast cereal market to help to help healthcare professionals to guide parents in choosing healthy products for their children. Study design: Observational study of the breakfast cereals available in the biggest supermarkets, discount stores and organic chains in France, Belgium and Luxembourg. Methods: An analysis of nutritional qualities using three indicators: Nutri-Score (initial and modified version), WHO Europe nutrient profile model, and Nova. Results: 645 products were listed; 559 excluding duplicates. A total of 28.8% are marketed to children and make up the group of "children's" cereals, 62.1% of cereals are Muesli, Oats and other cereal flakes (MOCF), and 54.9% are "organic". The study shows that "children's" cereals have a poorer nutritional profile: a higher proportion of Nutri-Score D, higher sugar content, lower fibre content, less conformity with the WHO Europe nutrient profile model and a higher proportion ofultra-processed. On the other hand, MOCF and "organic" products generally have a better nutritional profile: less sugar, more fibre, more Nutri-Score A, less Nutri-Score D and fewer ultra-processed products. Conclusions: Parents should therefore opt for cereals that do not bear any reference to children on the packaging.

RESUMEN

OBJECTIVE: To assess the effect of different front-of-package (FOPL) schemes on the objective understanding of the nutritional content and intention to purchase products, in Panama. DESIGN: Single-blinded multi-arm parallel-group randomised controlled trial. SETTING: Supermarkets across Panama. Participants were exposed to two-dimensional images of 15 mock-up products presented at random and balanced orders. Participants assigned to the intervention groups were exposed to mock-ups featuring one FOPL scheme: black octagonal warning labels (OWL), traffic-light labelling (TFL), or guideline daily amounts (GDA). Control group was not exposed to any FOPL scheme. PARTICIPANTS: Adult supermarket shoppers (n=1200). Participants were blinded to group assignment. RESULTS: Similar number of participants were randomised to and analysed in each group: OWL (n=300), TFL (n=300), GDA (n=300), and control (n=300). The odds for choosing to purchase the least harmful or none of the options more often was the highest in the OWL group. Compared to the control group, two times higher in the OWL group (OR 2·13, 95% confidence interval 1·60-2·84), and 57% higher in the TFL (1·57, 1·40-2·56), with no changes in the GDA (0·97, 0·73-1·29). OWL also resulted in the highest odds for correctly identifying the least harmful option, and for correctly identifying a product with excessive amounts of sugars, sodium and/or saturated fats. CONCLUSIONS: OWL performed best in helping shoppers to correctly identify when a product contained excessive amounts of nutrients of concern, to correctly identify the least harmful option, and to decide to purchase the least harmful or none of the options, more often.

RESUMEN

This study aimed to characterise the market-driven fortification of vitamins and minerals in packaged foods targeted at children in Brazil. We analysed 535 food labels using data collected in a census-type method (n = 5620) of food labels in a Brazilian supermarket in 2013. Micronutrients declared in nutrition claims and the ingredients list (synthetic compounds) were considered to be added for commercial purposes. Analysis of the ingredients list and nutrition claims showed that market-driven fortification of vitamins and minerals was present in 27.1% of foods. The main vitamins and minerals were vitamins A, B complex, C, D, calcium, iron and zinc. The food groups 'Milk and dairy products' and 'Sugars, sugary foods and snacks' had the highest frequencies of micronutrients declared in the ingredients list. Calcium, iron, phosphorus, zinc and all vitamins, except B7, were found to be added for commercial purposes. Micronutrients were found to be commonly added to packaged foods as a marketing strategy directed at parents and their children. Future studies should assess the amount of vitamins and minerals added to packaged foods targeted at children and whether intakes of vitamins and minerals in children are potentially excessive.

RESUMEN

BACKGROUND: Urbanization influences food culture, particularly in low- and middle-income countries where there is an increasing consumption of processed and pre-packaged foods. This shift is contributing to a rise in non-communicable diseases. Food labelling standards are crucial for regulating manufacturing practices and helping consumers make healthy food choices. We aimed to assess the compliance of local and imported pre-packaged snacks with Tanzanian and international labelling standards in Dar es Salaam, Tanzania. METHODOLOGY: A cross-sectional study was conducted on 180 snack products. A checklist based on Tanzanian and Codex labelling standards was used to evaluate adherence. We also examined factors influencing adherence, such as product origin, price, category, purchase location, and package size. RESULTS: The majority of the snacks demonstrated partial adherence to Tanzania (n = 97; 54%) and International (Codex) (n = 120; 67%) labelling standards. Imported products showed significantly better adherence to both Tanzanian (n = 46; 53%) and international (n = 42; 48%) standards. Notably, more than half (n = 110; 66.7%) of the products used English for labelling, and infrequently (n = 74; 41.4%) used the recommended World Health Organization Front-of-Pack Nutrition Labelling. Product category, origin, and package size were significantly associated with higher levels of international standard adherence (p < 0.05). CONCLUSION: The inadequate adherence to mandatory labelling standards and the scarce use of Swahili and FoPL highlight the need to strengthen labelling practices and potential challenges faced by consumers in understanding nutritional information. Thus, strengthening and emphasizing good labelling practices are urgently needed as we seek to address diet-related noncommunicable diseases.

RESUMEN

BACKGROUND: Some research shows that advertising for high-fat, sugar, or salt (HFSS) products is contributing to a shift in consumer preferences toward products of poor nutritional quality, leading to unhealthy nutritional intakes that increase the risk of obesity and chronic diseases. A strategy of displaying simple and understandable nutritional information (like the front-of-pack nutrition label Nutri-Score) in food messages could be an aid to help guide consumers' choice towards healthier products. METHODS: A randomized controlled experiment was conducted on 27,085 participants randomly assigned to two experimental conditions or a control condition. In both experimental conditions (independent variable: advertising messages with vs. without the Nutri-Score), participants were exposed to advertisements for diversified food products with contrasting nutritional quality and belonging to nine different food categories. Participants were then asked questions about their perception, affective evaluation, and intentions to purchase and consume the products. In the control condition, they were not exposed to the advertisements. RESULTS: Overall, interaction effects between the two variables (1) the messages with vs. without the Nutri-Score and (2) the nutritional quality of products, were significant for all dependent variables, with effect sizes between large and medium. Overall, the better the products' nutritional quality, the more positive their perceptions, affective evaluations, and intentions to buy and consume them. When the Nutri-score was displayed in advertising messages (vs. when it was not), perceptions, affective evaluation, and behavioral intentions: (1) became more positive for products of good nutritional quality (Nutri-score A and B), (2) became more negative for products of poor nutritional quality (Nutri-score D and E), (3) changed little or not at all for products of intermediate nutritional quality (Nutri-Score C). CONCLUSIONS: This research is the first in the literature to demonstrate that displaying the Nutri-Score in advertising messages assists consumers in directing their choices towards healthier foods. Regulations mandating the display of the Nutri-Score in food advertising could be an effective public health measure.

RESUMEN

CONTEXT: Food labelling is a global strategy recommended to reduce noncommunicable diseases. Few reviews, however, have focused on food label use in sub-Saharan Africa (SSA). OBJECTIVE: To determine the prevalence of food label use and describe determinants of food label use and purchasing decisions of adult consumers in SSA. DATA SOURCE: PubMed (Medline), Web of Science, Cochrane Central, and Google Scholar databases. DATA EXTRACTION: Search criteria included adults (aged ≥18 years), conducted in SSA, focusing on food label use or understanding and their determinants or determinants of food-purchasing decisions, and articles published in English. STUDY QUALITY AND DATA ANALYSIS: Risk-of-bias assessment of included studies was done using the Joann Briggs Institute checklist for prevalence studies. Publication bias was assessed using funnel plots and Egger's test. Analysis included narrative synthesis and moderator and meta-analyses of food label use. RESULTS: A total of 124 articles were found, of which 21 were included in the review. Of participants in the selected studies, 58% were female. About 80% reported food label use (either used sometimes or always) (70%-88%) (I2 = 97%; n = 6223), and regular use was estimated at 36% (28%-45%) (I2 = 97%; n = 5147). Food label use was influenced by level of income, education, employment status, and household size. Food-purchasing decisions were influenced by attributes such as expiry dates, price, and taste. Major recommendations reported were tailored education campaigns and reducing barriers to food label use. CONCLUSION: Most (80%) of adults in SSA reported using food labels; however, only about one-third used them consistently. Demographic and situation factors determined patterns in food label use, whereas product attributes influenced food purchasing decisions. Complexity of these determinants requires adopting tailored, multisectoral, theory-driven programs to improve food label use. SYSTEMATIC REVIEW REGISTRATION: Open Science Framework (https://osf.io/kc562).

RESUMEN

Sodium intake from pre-packaged foods is increasing in China and is well above the WHO recommendation of 5 g per day. The purpose of this study is to analyze the sodium content of pre-packaged foods collected by the National Institute for Nutrition and Health, Chinese Center for Disease Control and Prevention (NINH, China CDC) in 20 provinces of China from 2017 to 2022. The proportion of pre-packaged foods that meet or exceed the low-sodium, medium-sodium, and high-sodium classifications were analyzed. The proportion of pre-packaged foods that meet and do not meet the WHO global sodium benchmarks and the difference in sodium content between these foods was also calculated. High-sodium foods include sauces, dips, and dressings (3896 mg/100 g), convenience foods (1578 mg/100 g), processed fish products (1470 mg/100 g), processed meat products (1323 mg/100 g), processed poultry products (1240 mg/100 g), snack foods (750 mg/100 g), processed egg products (741 mg/100 g), and fine dried noodles (602 mg/100 g). A large number of pre-packaged foods currently collected in China have a sodium content above sodium benchmarks. This study provided data to support the assessment of sodium intake from pre-packaged foods in the Chinese population and the implementation of comprehensive salt reduction strategies.

RESUMEN

Nutrition labelling is any description intended to inform consumers about the nutritional properties of a food product and has focused primarily on nutrients. However, literature has shown that the nutritional quality of packaged foods is not limited to the amount of nutrients, considering that individuals do not consume only nutrients separately, but rather the entire food matrix. Therefore, to analyze the nutritional quality of a packaged food, it is necessary to read its ingredients. This scoping review aims to discuss (1) the list of ingredients as a source of health and nutrition information in food labelling; (2) opportunities to improve the nutrition labeling policies around the world. The study was carried out through a systematic search on Codex Alimentarius meeting reports. Results show that the list of ingredients is used as a source of nutritional and health information on food labelling; however, this label item is not considered in the regulatory field as a nutrition labelling requirement. It is suggested that nutrition labelling be discussed as a tool for food choices in the context of public health from a broader, consistent, convergent perspective, considering the list of ingredients as an item of nutrition labelling requirement to be included in public policies around the world.

RESUMEN

Condiments are a significant source of sodium in the diets of Chinese residents. This study aimed to analyze the nutrient content of China's major condiments and to provide support for setting the reference intake for condiments in order to take measures on salt reduction in China. Nutrition data for condiments were collected from the Database on Nutrition Labelling of Prepackaged Foods China in 2017-2022, and by online access to food composition databases from France, the UK, Belgium, and Japan. The analyses include 1510 condiments in China and 1565 related condiments in four countries, of which the descriptive indicators were examined such as median, IQR, and range. Cross-comparisons were made in terms of the difference between the content levels in five countries and the "WHO global sodium benchmarks". The results show that among the 15 types of condiments in China, sesame/peanut butter-based products have a relatively high content of energy, fat, and protein, namely, 2580 kJ/100 g, 50 g/100 g, and 22.2 g/100 g, respectively. In addition to salt, chicken extract/chicken powder, bouillon cubes, and soy sauce are also high in sodium. Furthermore, there were significant differences in the contents of energy and core nutrients across different products when benchmarking with similar condiments in the five countries (p < 0.001). The sodium content and fat content of some condiments are excessively high. Therefore, enhancing residents' consumption awareness and reducing the amount of condiments is of great significance for reducing China's per capita salt intake and promoting good health.

RESUMEN

OBJECTIVE: To evaluate the prevalence of 'High Fat Sugar Salt' (HFSS) products and front-of-pack nutrition labelling (FOPNL) characteristics across promoted products in UK online supermarkets. DESIGN: A cross-sectional survey conducted (December 2021-January 2022) on promoted products. Data on ingredients, nutritional composition and display of FOPNL were collected from product webpages. The UK's Nutrient Profiling Model and Multiple Traffic Light criteria were used to determine HFSS status and possession of inherent red traffic lights (iRTL), respectively. Data analysis determined the prevalence (i.e. percentage of products of the total number of products sampled) of HFSS; FOPNL and possession of iRTL. Chi-squared tests explored associations between these. SETTING: Three major UK online supermarket retailer websites. PARTICIPANTS: Product 'multibuy' and 'entrance' promotions, from selected product categories. RESULTS: Among the sampled 625 promoted products, the prevalence of HFSS was greater in entrance (73 %) compared with multibuy (41 %) promotions (χ2 (1) = 34, P < 0·05), with variations in the former across retailers (49-92 %). The prevalence of HFSS products in multibuy promotions offered by two retailers varied by category (i.e. Confectionery 94-97 %, Yogurts 20-20 %, Soft Drinks 16-33 %, Ready Meals 1·4-18 %). Not all promoted products displayed FOPNL on webpages (70 %) or images (52 %). A number of iRTL were found to be possessed by both HFSS and non-HFSS-promoted products. CONCLUSIONS: Prior to the 2022 implementation of Regulations restricting these, HFSS products were promoted in online supermarkets with varying display of FOPNL and possession of iRTL. Findings support future policy evaluation and mandatory digital FOPNL.

RESUMEN

The aim of the present work was to explore children's reaction to sugar reduction in the context of the implementation of nutritional warnings in Uruguay. The study was composed of two sessions involving three evaluation conditions: tasting without package information, package evaluation without tasting, and tasting with package information. A total of 122 children, ages ranging between 6 and 13 years old (47% girls) were involved in the study. In the first session, children's hedonic and emotional response to a regular and a sugar-reduced chocolate dairy dessert (without other sweeteners) was evaluated. In the second session, children first evaluated their expected liking, emotional associations and choice of packages differing in the presence of warning labels for excessive sugar content and cartoon character (2x2 design). Finally, they tasted the selected sample in the presence of the package and evaluated their liking, emotional associations, and intention to re-taste it. Although sugar reduction led to a significant reduction in overall liking, the dessert with 40% sugar reduction showed a mean overall score of 6.5 in a 9-point hedonic scale and was described using positive emoji (, , ). When the desserts were tasted with package information, no significant differences in the expected overall liking of the regular and sugar-reduced dessert were found. Regarding the effect of packaging elements, the presence of a warning label highlighting excessive content of sugar did not have a significant effect on children's choice. Instead, children's choices were defined by the presence of a cartoon character. Results from the present work provide additional evidence about the feasibility of reducing the sugar content and sweetness of dairy products targeted at children and stress the need to regulate the use of cartoon characters on products with an unfavorable nutritional profile. Methodological recommendations for sensory and consumer research with children are also discussed.

RESUMEN

Front-of-pack labelling (FOPL) systems, such as the Nutri-Score, play a crucial role in promoting healthy diets and raising consumer awareness. Our study aimed to gather the opinions of Polish experts on the Nutri-Score and its relation to an ideal information system. We conducted a Poland-wide expert opinion study using a cross-sectional design survey with 75 participants, who had an average of 18 ± 13 years of experience and were mainly employed at medical and agricultural universities. The data were collected with the CAWI method. The results showed that the most important features of an FOPL system were clarity, simplicity, consistency with healthy eating recommendations, and the ability to objectively compare products within the same group. While more than half of the respondents believed that the Nutri-Score provides an overall assessment of a product's nutritional value and facilitates quick purchasing decisions, it falls short in helping consumers compose a balanced diet and cannot be applied to all product groups. The experts also expressed concerns about the system's ability to account for a product's degree of processing, full nutritional value and carbon footprint. In conclusion, Poland's current labelling system needs expansion, but the Nutri-Score requires significant and detailed changes and validation against national guidelines and expert expectations before implementation.

RESUMEN

Nutritional warning labels are gaining relevance in the region of the Americas as a policy tool to reduce information asymmetry and encourage healthier food choices. However, empirical evidence about consumer experiences with warning labels after implementation is still scarce. In this context, the aim of the present work was to explore the use of nutritional warning labels after policy implementation in Uruguay, using a combination of eye-tracking and self-reported data. The study was conducted in three supermarkets, in two regional capitals, 19 months after the entry into force of the policy. A total of 224 participants were intercepted while entering the facilities of the supermarket and asked to wear a mobile eye-tracker while making their food purchases. Then, they were asked a series of questions about their awareness and use of warning labels. Although participants reported high awareness and understanding of the labels, active search and use at the point of purchase was low. Only 6% of the consumers declared having actively searched for the warning labels and 7% fixated their gaze on the labels. The majority of the participants (72%) who declared having seen the warnings on a product, purchased it anyway. However, 56% declared having changed their food choice decisions as a consequence of the implementation of the policy. Participants' accounts about reasons for (not) taking into account the warning labels provide relevant insights for the development of strategies to encourage citizens to increase policy effectiveness and encourage healthier food choices.

RESUMEN

Qualitative menu labelling can be defined as descriptive or non-numerical interpretive labels (e.g. traffic light labelling, healthy food symbols, messages or ingredient lists). Qualitative information seems to have a positive influence on consumers' food choices, particularly in institutional food service establishments, such as in universities. The aim of this systematic review was to assess the influence of different formats of qualitative menu labelling on food choices in university restaurants. This systematic review was guided by the Preferred Reported Items for Systematic Reviews and Meta-Analyses (PRISMA) and Synthesis Without Meta-Analysis (SWiM) and conducted vote counting of studies based on the direction of effect. Studies were retrieved from Cochrane Library, Scopus, MEDLINE, LILACS, SciELO and Web of Science databases and reference lists of selected articles. Experimental and quasi-experimental studies were included. Two independent researchers searched and extracted the data and assessed the methodological quality using the Effective Public Health Practice Project (EPHPP) Quality Assessment Tool for Quantitative Studies. From the initial search (460 records), four papers were selected, plus one paper identified in a previous study and a further six from an update search, totalling 11 included studies, reporting 14 different interventions (n = 499 174). Types of interventions included the use of symbols and the inclusion of traffic light labelling. Outcomes of interest were food choice, expressed as mean, median or percent healthy food choices or purchases. Qualitative menu labels increased healthy food choices and/or purchase behaviour, with 10 of 12 interventions favouring the intervention (83%; 95%CI 55-95%; p = 0.0386). Most of the studies favouring the intervention used healthy food symbols for healthier foods or food components, alone or in association with another intervention and were of moderate and weak quality. These findings may serve as a basis for the implementation of nutrition information policies in university restaurants.

RESUMEN

An unhealthy diet is a leading contributor to the increasing burden of overweight and obesity. Front-of-pack labelling (FOPL) is being recognized as a policy strategy to promote healthier choices yet there is limited evaluation of FOPL to suggest if it is effective for all population subgroups. This systematic review aimed to assess the impact of FOPL on consumer understanding and usage across socio-economic gradients. Six electronic databases were searched through a systematic search process using key terms for FOPL and socioeconomic status (SES) from 2011 to March 2022 to include studies evaluating the effectiveness of FOPL. A narrative synthesis was conducted and the results were assessed according to the effects of FOPL on consumer awareness, understanding, and usage across SES. The review included 36 articles. In general, people of all SES groups were aware of and more likely to pay attention towards FOPL than the nutrition information panel provided on the back of the package. However, the understanding and usage were relatively poor, particularly in low SES groups. While studies conducted in low SES populations suggest FOPL increased the purchase intention of healthy products, the stratified analysis across SES showed less beneficial effects in low SES individuals. The findings highlight simplified and easy-to-understand FOPLs such as Nutri-score and traffic light labelling are likely to be effective for all populations including low SES groups. Overall, the review suggests FOPLs are more visible than the nutrition information panel and may guide healthier food choices for people of all SES backgrounds. It is unclear whether FOPL influences actual purchasing and food intake as there are insufficient studies comparing the effects among higher and lower SES populations.

RESUMEN

Commercially produced complementary foods (CPCF) have the potential to fill nutritional gaps in the diets of older infants and young children. This study evaluated the accuracy of nutrient declarations on labels of 43 commonly available CPCF in three peri-urban/urban locations: Khsach Kandal district, Cambodia (n = 11); Bandung, Indonesia (n = 11) and Guédiawaye and Dakar departments, Senegal (n = 21). Label values (LV) from product nutrient declarations were compared to analytical values (AV) derived from laboratory nutrient analysis for macronutrients (carbohydrate, protein and total fat), nutrients of public health concern (saturated fat, total sugar and sodium), and micronutrients of interest (calcium, iron and zinc). European Union guidance for nutrition label accuracy was used to set tolerance ranges for each nutrient LV relative to AV. LV were missing for one or more nutrients in 88.4% (n = 38) of the CPCF products and no CPCF met EU tolerance thresholds for all nine nutrients assessed. Over half of products with LV for key micronutrients (55.6%, n = 10/18) and macronutrients (54.8%, n = 23/42) met tolerances for LV accuracy. Eighty-five percent (n = 11/13) of products with LV for nutrients of public health concern were determined to be accurate. Nutrient content claims for iron appeared on 19 (44.2%) of the 43 products. Of the products which made an iron content claim, 26.3% had inaccurate LV with the majority of these containing less iron than declared. Regulatory action is needed to ensure that CPCF labelling communicates complete and accurate nutrient content information that enables caregivers to make informed decisions for feeding older infants and young children.

RESUMEN

Nutritional warnings have gained popularity, particularly in the region of the Americas, to facilitate the identification of products with excessive content of nutrients associated with non-communicable diseases and encourage healthier food choices. Although warnings have been shown to be effective, an in-depth understanding of the reasons why some consumers do not use them is still lacking. The aim of the present work was to explore self-reported use of nutritional warnings and to identify the reasons for not considering nutritional warnings for making food purchase decisions after policy implementation in Uruguay. A non-probabilistic sample of 858 Uruguayan participants was recruited using an advertisement on Facebook and Instagram. Through an online survey, self-reported use of nutritional warnings was asked using a closed-open ended questions. Participants who reported not considering warnings to make their purchase decisions were asked to explain the reasons why using an open-ended question. Responses were analysed using deductive coding, based on the Behavioural Drivers Model. Thirty seven percent of the participants stated that the warnings had not influenced their purchase decisions. Motives for not being influenced by the warnings were related to lack of interest, attitudes, lack of perceived self-efficacy, cognitive biases and limited rationality when making purchase decisions. In addition, structural barriers, such as availability, cost and trust in the food industry also emerged from participants' responses. Strategies to encourage the use of warnings should include communication campaigns and policies to address structural barriers related to the perceived availability and affordability of healthy foods.

RESUMEN

OBJECTIVE: This study aimed to identify correlates of nutrition label awareness and use, particularly subgroup differences among consumers. Two label types were assessed: (1) nutrition facts tables (NFt) in Australia, Canada, Mexico, UK, and USA and (2) front-of-package (FOP) labels, including mandatory Guideline Daily Amounts (Mexico), voluntary Health Star Ratings (Australia) and voluntary Traffic Lights (UK). DESIGN: Respondents were recruited using Nielsen Consumer Insights Global Panel (n 21 586) and completed online surveys in November-December 2018. Linear regression and generalised linear mixed models examined differences in label use and awareness between countries and label type based on sociodemographic, knowledge-related and dietary characteristics. SETTING: Australia, Canada, Mexico, UK and USA. PARTICIPANTS: Adults (≥18 years). RESULTS: Respondents from the USA, Canada and Australia reported significantly higher NFt use and awareness than those in Mexico and the UK. Mexican respondents reported the highest level of FOP label awareness, whereas UK respondents reported the highest FOP label use. NFt use was higher among females, 'minority' ethnic groups, those with higher nutrition knowledge and respondents with 'adequate literacy' compared with those with 'high likelihood of limited literacy'. FOP label use was higher among those with a 'high likelihood of limited literacy' compared with 'adequate literacy' across countries. CONCLUSIONS: Lower use of mandatory Guideline Daily Amount labels compared with voluntary FOP labelling systems provides support for Mexico's decision to switch to mandatory 'high-in' warning symbols. The patterns of consumer label use and awareness across sociodemographic and knowledge-related characteristics suggest that simple FOP labels may encourage broader use across countries.

RESUMEN

ISSUE ADDRESSED: Consumption of energy drinks is a public health concern, particularly in adolescents and young adults. This study explored energy drink consumers' reactions to an energy drink-specific warning label (risk of cardiac effects) and a more general sugary drink warning label (risk of obesity). METHODS: An online experimental study randomly allocated Australian energy drink consumers aged 18-39 years (N = 435) to view one of two label conditions (cardiac effects or obesity). Participants were assessed on: intention to reduce energy drink consumption, perceived health threat, perceived label effectiveness and policy support for energy drink warning labels. RESULTS: Mean intentions to reduce consumption scores were similar across the two label conditions (Mobesity  = 2.5, Mcardiac  = 2.6) overall; and were higher for the cardiac label (compared to obesity label) for some subgroups: females (Mobesity  = 2.3, Mcardiac  = 2.8; p = .037), older (25-39 years; Mobesity  = 2.4, Mcardiac  = 2.8; p = .016); and higher education level (Mobesity  = 1.9, Mcardiac  = 2.7; p = .004). While perceived health threat measures were higher for obesity than cardiac effects, perceived label effectiveness measures of 'believable' and 'relevant to me' were higher for the cardiac label than the obesity label (believable: 71.0% vs 56.1%; relevant: 42.5% vs 29.4%). Participants who viewed the cardiac label were more likely to support policy than those shown the obesity label (OR = 1.6, 95%CI [1.1, 2.3], p = .02). CONCLUSIONS: Health effect warnings labels were perceived by energy drink consumers to be impactful and are supported. Labels with energy drink-specific health effects may offer additional benefit. SO WHAT?: Policy makers can feel confident that warning labels on energy drinks will confer public health benefit.

RESUMEN

Little can be added about the worldwide concern over the exponential increase in obesity and child overweight problems. Much of the unhealthy eating habits occur at the time of food choice. The enormous influence of marketing strategies in general, and packaging in particular, has been highlighted here. In this respect, public policies that tend to direct choices toward healthier options have been developed. However, the usefulness of such policies will depend on evidence of how different packaging elements can influence children. This systematic review (SR) aims to compile the knowledge available to date on the influence of packaging on food choices and eating behaviours in children. Methodologically, the Preferred Reporting Items for Systematic Reviews (PRISMA) guidelines have been followed to select papers. We also assessed the risk of bias in the studies analysed using the Newcastle-Ottawa Quality Assessment Scale (NOS). The initial search strategy found 2,627 articles, although only 20 of them met the eligibility criteria. Data from the studies were extracted, categorised, and analysed. The results indicate that most of the packaging elements have some effect on children's food choices or food intake. The use of Cartoon is the element with the most consistent evidence of influence. Despite the number of studies and public initiatives developed to promote this informative and persuasive element, less consistency has been found regarding the effect of Nutrition Labelling. Therefore, the results found should be considered by both governments and organisations when promoting public policies that work for the wellbeing of children.
