RESUMO

OBJECTIVE: Examine the key elements that characterise social media advertisements targeted at adolescents by asking adolescents which features of Instagram ads promoting ultra-processed products make them designed to appeal to adolescents. DESIGN: Instagram ads promoting ultra-processed products and brands were selected from a database in which ads had been classified regarding whether they were primarily targeted at adolescents from an adult perspective. Adolescents completed a sorting task in small groups and were requested to reach a consensus through discussions and sticky notes regarding whether sixty ads were designed to appeal to them. The sorting task was analysed using content analysis based on inductive coding. SETTING: One private secondary school and two after-school clubs. PARTICIPANTS: Convenience sample of 105 Uruguayan adolescents aged 11-17 years. RESULTS: Ten categories were identified regarding the reasons for sorting ads as (not) designed to appeal to adolescents: product type, graphic design, explicit references to age groups, language, activities or themes, memes, celebrities, characters, promotions and novelty. Product type emerged as a key element, with adolescents perceiving ads as designed to appeal to them simply because they promoted specific products. CONCLUSIONS: This research contributes to the validation of criteria defined in previous studies and can be used for the development of tools to monitor the prevalence and power of adolescent-targeted digital marketing. However, the importance attributed to type of product suggests that regulations should not exclusively focus on exposure to digital marketing specifically targeted at adolescents but also on exposure to marketing in general.

RESUMO

The information included on food packages has a crucial role in influencing consumer product associations and purchase decisions. In particular, visual and textual cues on processed and ultra-processed products can convey health-related associations that influence consumer healthiness perception and purchase decisions. In this context, the present work aimed to explore the use of health-related cues on the packages of processed and ultra-processed products sold in Uruguay to provide insights for policy making. A total of 3813 products from thirty-four different food categories found in four of the most important supermarket chains in Uruguay were surveyed. The textual and visual information included on the packages as well as the nutritional composition of the products were analysed. Results showed that 67 % of the products included at least one health-related cue. Pictures of culinary ingredients, natural and minimally processed foods were the most frequent health-related cue, followed by references to naturalness and claims related to critical nutrients. The prevalence of health-related cues largely differed across product categories, ranging from 100 to 17 %. The relationship between the presence of health-related cues on the packages and the excessive content of nutrients associated with non-communicable diseases was assessed using a gradient boosting model, which showed limited predictive ability. This suggests that the inclusion of health-related cues on food packages was not strongly related to the nutritional composition of products and therefore cannot be regarded as a healthiness indicator. These results stress the need to develop stricter labelling regulations to protect consumers from misleading information.

RESUMO

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.

RESUMO

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.

RESUMO

The present work explored the relationship between discretionary salt usage and personal characteristics, using boosted regression trees (BRT). Specifically, the focus was on how socio-demographic characteristics and personality traits linked to risk perception and time orientation impact on discretionary salt consumption patterns. For this purpose, an online cross-sectional survey with a convenience sample of 498 Uruguayan participants was carried out. Participants completed the consideration of future consequences (CFC) scale adapted for eating behaviour, a short survey about discretionary salt consumption patterns and indicated their degree of agreement with statements measuring perceived risk of sodium consumption. Finally, socio-demographic data were collected. BRT were applied to build predictive models that related discretionary salt usage to socio-demographic characteristics, the two factors of the CFC-Food scale (consideration of the future and consideration of the immediate consequences of eating behaviour), and the two factors of the perceived risk of sodium consumption scale (severity of perceived risks and risk compensation). Age, time orientation and perceived risk were the most relevant explanatory variables for discretionary salt usage. Older people had a lower likelihood of adding salt to food, either at home or when eating out. In addition, individuals who tend to be present rather than future oriented, as well as those with low perception of risk severity and susceptibility were more likely to add salt to foods. Results from the present work suggest that communication campaigns to reduce discretionary salt intake should mainly focus on stressing the short-term health benefits of reducing sodium intake and raising perceived susceptibility.

RESUMO

Adolescents are particularly vulnerable to digital food marketing. However, research on adolescents' recall, awareness, and opinions of this type of marketing is still scarce. Accordingly, the present study aimed to conduct an in-depth examination of adolescents' experiences with digital food marketing. A convenience sample of 209 adolescents was recruited at two private educational institutions and a public health facility in Montevideo, the capital city of Uruguay. Semi-structured group interviews were conducted, recorded in audio and transcribed. The transcripts were analyzed using content analysis based on a deductive-inductive approach. Results showed that participants were highly exposed to digital food marketing, as they all remembered having seen advertisements, with those of fast-food restaurants and food-ordering apps being the most frequently mentioned. According to the adolescents' accounts, images, colors, music, oversized portions, product novelty, price promotions and celebrities were the most memorable aspects of food advertisements. Participants recognized the effect of advertisements on product awareness and wanting, and, to a lesser extent, on actual purchase and consumption behavior. Factors that were thought to mediate the impact of digital marketing on food choice were also identified. In the final part of the interviews, participants proposed strategies to reduce the effect of digital marketing on their food choices, which included both regulatory approaches to reduce exposure to digital marketing of unhealthy foods and behavior change communication. Together, the current findings provide insights for the development of multifaceted strategies to reduce the effects of digital food marketing on the eating habits of adolescents.

RESUMO

OBJECTIVE: To explore adolescents' views about the foods they consume and to identify their ideas about strategies to encourage healthier eating habits. DESIGN: Individual questionnaires based on open-ended questions and group discussions (6-8 participants) were used to address the objectives. Data were analysed using content analysis based on deductive-inductive coding. SETTING: Montevideo and its metropolitan area (Uruguay, Latin America). PARTICIPANTS: Totally, 102 adolescents (aged between 11 and 15 years, 52 % female) recruited at two educational institutions. RESULTS: Adolescents reported frequently consuming ultra-processed products and fast food although they were perceived as bad for their health, whereas they reported an infrequent consumption of fruits and vegetables. Multifaceted strategies to promote healthy eating habits emerged from adolescents' accounts, including public awareness campaigns, nutrition education programmes, nutrition label standards and regulations, and changes in food availability and affordability. CONCLUSIONS: Results from the present work suggest that co-creation with adolescents may be an effective way to inform the development of strategies to promote healthier eating habits. The strategies suggested by adolescents were mainly focused on behaviour change communication, who emphasised the importance of social media and the involvement of celebrities and influencers. The need for educational and communication strategies to raise awareness of the social and environmental drivers of eating patterns among adolescents was identified.

RESUMO

OBJECTIVE: To analyse the process for the development and implementation of mandatory nutritional warning labels in Uruguay, in order to inform future nutrition policy making and strategic engagement by public health actors. DESIGN: The study design drew on policy analysis methodology and case study research methodology. Two main sources of information were selected and analysed for the current study: eighteen official documents from the Uruguayan government and 259 news reports, published between June 2017 and February 2021. SETTING: Uruguay, Latin America. RESULTS: The Uruguayan Ministry of Public Health led a cross-sectoral working group composed of diverse governmental stakeholders, international organisations and the academia to develop the front-of-package nutrition labelling policy. A robust evidence-based approach, based on rigorous scientific knowledge generated in the country, was followed. However, changes in the systemic governing coalition as a consequence of a change in government led to a delay in the entry into force and changes in the regulation. The food industry was the main opponent to the warning label regulation and relied on widely reported corporate political activities to influence the policy process: information and messaging, legal action, policy substitution, opposition, fragmentation and destabilisation. CONCLUSIONS: Key insights to inform future policy action in Uruguay and other jurisdictions were derived. Results stressed the importance of an evidence-based approach for policy design and the early engagement with actors from all the political system.

RESUMO

OBJECTIVE: To explore the use of references to the COVID-19 pandemic as part of the marketing strategies used on Facebook to promote ultra-processed products. DESIGN: A search for Facebook accounts of ultra-processed products was performed using a master list of products commercialised in two online supermarkets in Uruguay. For each of the identified Facebook accounts, all the content posted from the confirmation of the first cases of COVID-19 in Uruguay, on 14 March 2020, until 1 July 2020 was recorded. Posts including mentions to COVID-19, social distancing measures or their consequences were identified and analysed using content analysis. SETTING: Uruguay, Latin America. RESULTS: A total of 135 Facebook accounts were identified, which generated a total of 1749 posts related to ultra-processed products, from which 35 % included references to COVID-19. The majority of the posts included references to prevention measures. Approximately one-third of the posts included proposals of activities to do at home, most of which were linked to a healthy lifestyle. Tips for coping with quarantine and descriptions of the charitable work undertaken by brands were also identified. CONCLUSIONS: Results from the present work provide evidence that industries of ultra-processed products have taken advantage of the COVID-19 pandemic to promote their products, create positive associations with the brands and improve their image as part of their digital marketing strategies.

RESUMO

OBJECTIVE: To assess the effects of nutritional warnings during the first month after the date of full compliance by the food industry in Uruguay in terms of citizen awareness, self-reported use and ability to understand nutritional information. DESIGN: The present work encompassed two online studies, conducted before (Study 1) and during the first month after the date of full compliance by the food industry (Study 2). An after-only design was used to assess awareness of the policy, exposure to nutritional warnings on food packages and self-reported use of warnings for making purchase decisions in Study 2. An after-only with control group experimental design was used to assess the effect of nutritional warnings on understanding of nutrition information in Studies 1 and 2. SETTING: Uruguay, one of the Latin American countries, that has recently implemented nutritional warnings. PARTICIPANTS: A non-probabilistic sample of 1772 participants was recruited using Facebook advertisements targeted at Uruguayan adult users. RESULTS: High awareness and self-reported use of nutritional warnings during the first month after the date of full compliance in Uruguay were observed. In addition, the before and after comparison showed that the implementation of warnings increased citizens' ability to use nutritional information to compare products and to identify products with excessive content of sugar, fat, saturated fat and sodium. CONCLUSIONS: The current study confirms results from experimental studies and provides additional evidence to support the implementation of nutritional warnings as one of the public policies that can contribute to tackle obesity and non-communicable diseases.

RESUMO

OBJECTIVE: To explore Uruguayan paediatricians' personal recommendations about complementary feeding and to assess if they are aligned with current guidelines and scientific evidence. DESIGN: A questionnaire composed of open-ended questions was used to explore foods recommended to start complementary feeding, foods regarded as the most important during the first meals, recommendations for delayed introduction of foods and foods that should be avoided. Reasons underlying the recommendations were also explored. SETTING: Montevideo, the capital city of Uruguay (Latin America). PARTICIPANTS: A total of 212 paediatricians were recruited during a National Pediatrics Conference, organised by the Uruguayan Society of Pediatrics. RESULTS: The recommendations about complementary feeding provided by paediatricians to parents and caregivers in Uruguay seemed not to be fully aligned with the guidelines provided by the Ministry of Health. Paediatricians recommend a rigid food introduction sequence, characterised by the early introduction of soft pureed vegetables and fruits, followed by meat and the delayed introduction of allergenic foods. Food diversity and the concept of ultra-processed were not frequently identified in the responses. CONCLUSIONS: Results stress the importance of developing educational and communication approaches targeted at paediatricians to contribute to the uptake of updated recommendations regarding complementary feeding.

RESUMO

OBJECTIVE: The information displayed on the packages of feeding bottles and teats commercialised in Montevideo (Uruguay) was analysed using content analysis with the goal of identifying key marketing practices that may discourage breast-feeding. DESIGN: The study was conducted as part of the periodic assessment performed by the Uruguayan government to monitor the marketing of breast milk substitutes. All the feeding bottles and teats sold in forty-four retail outlets selling breast milk substitutes were purchased. The information available on the packages was analysed using content analysis and descriptive statistics. SETTING: Montevideo, Uruguay. RESULTS: A total of 197 feeding bottles and 71 teats were found. The majority of the packages included information to enable caregivers to adequately use the products, including recommended age, instructions on how to use the products and instructions on the use of hygienic practices. However, the packages frequently included information that implied that bottle feeding was equivalent to breast-feeding, particularly from a physiological perspective, or that idealised product use. Idealisations included ability to reduce colic, improvements in the feeding experience and improvements in children's health, well-being and development. Statements on the superiority of breast-feeding were infrequent. CONCLUSIONS: The results from the present work showed the high prevalence of marketing practices on the packages of feeding bottles and teats that may discourage breast-feeding. Stricter and more detailed regulations seem necessary to enable caregivers to make informed feeding decisions for infants.

RESUMO

The aim of the present work was twofold: (i) to evaluate the effect of nutritional warnings and health-related packaging cues (nutrient claim and images of natural foods) on consumers' food choices, and (ii) to evaluate the influence of two types of messages (gain-framed and loss-framed) aimed at encouraging the use of such warnings and packaging cues on food choices. A total of 510 participants were recruited using an advertisement on Facebook and Instagram targeted at Uruguayan adult users. Participants were randomly allocated to one of three experimental groups: control (n = 167), loss-framed messages (n = 177) and gain-framed messages (n = 166). Then, they completed a choice-conjoint task involving packages of crackers differing in three variables: nutritional warnings (present vs. absent), nutrient claim (present vs. absent) and images of seeds and wheat (present vs. absent). Warnings were the most relevant package element driving choices, even when participants were not exposed to any type of message. Exposure to loss-framed messages led to changes in the relative importance attached to the package characteristics, whereas gain-framed messages did not. Graphic pieces conveying messages encouraging the use of nutritional warnings by stressing the negative consequences of excessive consumption of sugar, fat, and sodium increased the relative importance attached to nutritional warnings and decreased the relative importance attached to health-related cues (nutrient claims and images of seeds and wheat). These results suggest that public awareness campaigns aimed at encouraging citizens to use nutritional warnings should emphasize the negative health consequences of excessive intake of sugar, fat, and sodium.

RESUMO

OBJECTIVE: To explore the conceptualisation of healthy food by citizens and how they judge the healthiness of ultra-processed foods. DESIGN: Four focus groups were conducted using a semi-structured discussion guide. Focus group discussions were held about the concept of healthy food, what characterise a healthy product and healthiness perception of ultra-processed products. Transcripts of the focus groups were analysed following an inductive coding approach. SETTING: Uruguay, one of the Latin American countries with the highest prevalence of overweight and obesity. PARTICIPANTS: Fifty-two adult Uruguayan participants, diverse in terms of gender, age, educational level and socio-economic status. RESULTS: In agreement with previous studies on lay perceptions of healthy eating, the conceptualisation of healthy food was mainly focused on food characteristics. Although participants regarded lack of processing as a cue for healthiness, they did not categorise all ultra-processed products as unhealthy. Albeit some product categories were automatically regarded as unhealthy, participants considered that other categories could include healthy and unhealthy products. In such cases, they explicitly referred to several simplified cognitive strategies to judge whether an ultra-processed product is healthy or not. Results showed that participants tended to rely on simple cues, such as label design, nutrient claims, brand, price and country of origin as indicators of product healthiness. CONCLUSIONS: Healthiness perception of ultra-processed products seems to be largely influenced by heuristics, which stresses the need to implement policies that make the potential negative effects of ultra-processed products salient.

RESUMO

The inclusion of sodium warnings on food packages has been proposed as a means to encourage population to reduce sodium intake. However, consumers who focus on today rather than tomorrow or consumers who downplay or underestimate risks might pay little attention to warnings. The aim of the present study was to explore whether time orientation and perceived risk of sodium consumption may moderate the influence of sodium warnings on food choices. An online study involving 498 Uruguayan participants was carried out. Participants evaluated pairs of bread packages differing in three 2-level variables (sodium warning, type of bread and brand) and were asked to indicate the one they would choose if they were in a supermarket. Then, they answered a scale on 'consideration of future consequences' adapted to eating habits, and responded to statements measuring perceived risk of sodium consumption. Results revealed that sodium warnings had a significant effect on participants' choices. However, the efficacy of warnings was moderated by time orientation and risk perception. A focus on immediate consequences and thinking that the risk associated with sodium consumption can be compensated, decreased the efficacy of the sodium warning. These results provide experimental evidence of the potential of warnings to discourage consumption of products with high sodium content and suggest that communication campaigns accompanying the introduction of warnings should promote a future-oriented vision on eating habits, raise risk awareness and stress that the risks are not easily compensated.

RESUMO

OBJECTIVE: Nutritional warnings have recently been suggested as a simplified front-of-pack nutrition labelling scheme to facilitate citizens' ability to identify unhealthful products and discourage their consumption. However, citizens' perspective on this policy is still under-researched. The objective of the present work was to study how citizens perceive nutritional warnings and to evaluate public support of this policy, with the goal of deriving recommendations for the design of policy measures accompanying the introduction of nutritional warnings. DESIGN: An online survey with 1416 Uruguayan citizens, aged 18-75 years, 61 % female, was conducted. Participants had to answer a series of questions (open-ended and multiple-choice) related to their perception of warnings as a front-of-package nutrition labelling scheme. RESULTS: Participants showed a positive attitude towards nutritional warnings, which were regarded as easy to understand and to identify on food packages. The majority of respondents emphasized that they would take nutritional warnings into account when making their food choices, stating that they would allow them to make informed choices and, consequently, to increase the quality of their diet and their health status. Health motivation appeared as a crucial driver for taking nutritional warnings into consideration. CONCLUSIONS: A high level of public support for nutritional warnings was observed. Responses can be used to derive a range of recommendations for a policy mix that should synergistically support the introduction of nutritional warnings and encourage citizens to take them into account when making their food purchases.

RESUMO

OBJECTIVE: Warnings have recently been proposed as a new type of directive front-of-pack (FOP) nutrition labelling scheme to flag products with high content of key nutrients. In the present work, this system was compared with the two most common FOP nutrition labelling schemes (Guideline Daily Amounts (GDA) and traffic-light system) in terms of goal-directed attention, influence on perceived healthfulness and ability to differentiate between products. Design/Setting/Subjects Goal-directed attention to FOP labels was evaluated using a visual search task in which participants were presented with labels on a computer screen and were asked to indicate whether labels with high sodium content were present or absent. A survey with 387 participants was also carried out, in which the influence of FOP labels on perceived healthfulness and ability to identify the healthful alternative were evaluated. RESULTS: Warnings improved consumers' ability to correctly identify a product with high content of a key nutrient within a set of labels compared with GDA and received the highest goal-directed attention. In addition, products with high energy, saturated fat, sugar and/or sodium content that featured warnings on the label were perceived as less healthful than those featuring the GDA or traffic-light system. Warnings and the traffic-light system performed equally well in the identification of the most healthful product. CONCLUSIONS: Results from the present work suggest that warnings have potential as directive FOP nutrition labels to improve consumer ability to identify unhealthful products and highlight advantages compared with the traffic-light system.

RESUMO

OBJECTIVE: Warnings are a new directive front-of-pack (FOP) nutrition labelling scheme that highlights products with high content of key nutrients. The design of warnings influences their ability to catch consumers' attention and to clearly communicate their intended meaning, which are key determinants of their effectiveness. The aim of the present work was to evaluate the influence of design features of warnings as a FOP nutrition labelling scheme on perceived healthfulness and attentional capture. DESIGN: Five studies with a total of 496 people were carried out. In the first study, the association of colour and perceived healthfulness was evaluated in an online survey in which participants had to rate their perceived healthfulness of eight colours. In the second study, the influence of colour, shape and textual information on perceived healthfulness was evaluated using choice-conjoint analysis. The third study focused on implicit associations between two design features (shape and colour) on perceived healthfulness. The fourth and fifth studies used visual search to evaluate the influence of colour, size and position of the warnings on attentional capture. RESULTS: Perceived healthfulness was significantly influenced by shape, colour and textual information. Colour was the variable with the largest contribution to perceived healthfulness. Colour, size and position of the warnings on the labels affected attentional capture. CONCLUSIONS: Results from the experiments provide recommendations for the design of warnings to identify products with unfavourable nutrient profile.

RESUMO

The aim of this work was to evaluate consumer visual processing of food labels when evaluating the salt content of pan bread labels and to study the influence of label design and nutritional labelling format on consumer attention. A total of 16 pan bread labels, designed according to a full factorial design, were presented to 52 participants, who were asked to decide whether the sodium content of each label was medium or low, while their eye movements were recorded using an eye tracker. Results showed that most participants looked at nutrition labels and the traffic light system to conclude on the salt content of the labels. However, the average percentage of participants who looked at the actual sodium content was much lower. Nutrition information format affected participants' processing of nutrition information. Among other effects, the inclusion of the traffic light system increased participants' attention towards some kind of nutrition information and facilitated its processing, but not its understanding.

RESUMO

Perceived freshness is a key determinant of consumers' food choices but remains an imprecisely defined concept. A comprehensive and consumer-centric definition of freshness appears to be lacking, and the present research was situated in this knowledge gap, seeking, in particular, to explore the complexity of freshness in consumers' minds. People from the USA (n = 2092) took part in an online survey and completed a text highlighting task. Herein, participants read a text that described different aspects of freshness and the technologies used to prolong freshness during storage. While reading, they used highlighting functions within the software to indicate text content that they liked/disliked or agreed/disagreed with. The combined results from text highlighting and responses to the open-ended question "Considering the fruit you eat, why is freshness important to you?" confirmed that freshness is a complex construct with multiple dimensions and suggested that the complexity of freshness extends from food in general to specific product categories (in the case of fruit and apples). Further, the findings showed that freshness is desired by consumers because fruit are perceived as healthier and better tasting. The findings revealed negative attitudes towards stored fruit among participants, but also indicated some acceptance of the fact that some storage was unavoidable. Results provide useful insights to the development for communication strategies to increase consumer acceptance of stored apples and fruits in general.
