impact of front of pack nutrition information and Label Design on children s choice of two snack foods comparison of warnings and the traffic light system
Appetite, 2017Co-Authors: Alejandra Arrua, Maria Rosa Curutchet, Ana Gimenez, Natalia Rey, Patricia Barreto, Nadya Golovchenko, Andrea Sellanes, Guillermo Velazco, Medy Winokur, Gaston AresAbstract:Abstract Research on the relative influence of package features on children's perception of food products is still necessary to aid policy Design and development. The aim of the present work was to evaluate the relative influence of two front-of-pack (FOP) nutrition Labelling schemes, the traffic light system and Chilean warning system, and Label Design on children's choice of two popular snack foods in Uruguay, wafer cookies and orange juice. A total of 442 children in grades 4 to 6 from 12 primary schools in Montevideo (Uruguay) participated in the study. They were asked to complete a choice-conjoint task with wafer cookies and orange juice Labels, varying in Label Design and the inclusion of FOP nutrition information. Half of the children completed the task with Labels featuring the traffic-light system (n = 217) and the other half with Labels featuring the Chilean warning system (n = 225). Children's choices of wafer cookies and juice Labels was significantly influenced by both Label Design and FOP nutritional Labels. The relative impact of FOP nutritional Labelling on children's choices was higher for the warning system compared to the traffic-light system. Results from the present work stress the need to regulate the Design of packages and the inclusion of nutrient claims, and provide preliminary evidence of the potential of warnings to discourage children's choice of unhealthful products.

influence of Label Design on children s perception of 2 snack foods
Journal of Nutrition Education and Behavior, 2017Co-Authors: Alejandra Arrua, Leandro Machin, Joseline Martinez, Maria Rosa Curutchet, Lucia Antunez, Ana Gimenez, Leticia Vidal, Gaston AresAbstract:Abstract Objective To evaluate the influence of Label Design on children's perception of 2 popular snack foods across 3 income levels. Design Labels of 2 snack products (yogurt and sponge cake) were Designed using a fractional factorial Design with 3 2-level variables: cartoon character, nutrition claims, and front-of-package nutritional information. Participants A total of 221 children (aged 9–13 years) from Montevideo, Uruguay, with different income levels, participated in the study. Main Outcome Measures Children's attitude toward and liking of 2 food products. Results Low-income children showed a more positive attitude toward the products than did middle- and high-income children. The inclusion of a cartoon character in sponge cake Labels significantly affected hedonic expectations regardless of income. Middle- and high-income children tended to use the term funny more frequently and the term boring less frequently to describe Labels that included the cartoon character, compared with those that did not. Conclusions and Implications Results showed that the inclusion of cartoon characters on food Labels is associated with fun. Low-income children seem more susceptible to the marketing strategies of food companies than do middle- and high-income children.

influence of Label Design on children s perception of two snack foods comparison of rating and choice based conjoint analysis
Food Quality and Preference, 2016Co-Authors: Gaston Ares, Alejandra Arrua, Leandro Machin, Joseline Martinez, Maria Rosa Curutchet, Lucia Antunez, Leticia Vidal, Ana GimenezAbstract:The contribution of package Design to the marketing of food products targeted at children has increased in the last years, which makes it necessary to study how Label Design affects children’s perception of food products in order to inform policy Design and development. Considering that methodological selection is one of the major challenges when conducting research with children, the present work aimed at comparing rating and choice-based conjoint to study the influence of three Design variables (cartoon characters, nutrition claims and traffic-light system) on the hedonic reaction of school-aged children towards Labels of two popular snack foods: yogurt and sponge cake. A total of 238 children in grades 1–6 from a private primary school in Montevideo (Uruguay) participated in the study. Participants were divided into two groups of similar size who performed either a rating or a choice-based conjoint task. The rating-based conjoint involved the evaluation of 8 Labels using a hedonic scale, whereas in the choice task children had to select the Label they would like the most from each of 8 pairs of Labels. None of the variables was found to significantly affect children’s hedonic scores in the rating-based conjoint analysis. On the contrary, choice-based conjoint proved to be easily understood and enabled to discriminate among Labels. Results from this approach showed that the inclusion of cartoon characters and nutrition claims positively influenced children’s preferences. Implications for research and policy making in Label Design for children are discussed.

How do Design features influence consumer attention when looking for nutritional information on food Labels? Results from an eye-tracking study on pan bread Labels
International journal of food sciences and nutrition, 2013Co-Authors: Lucia Antunez, Ana Gimenez, Leticia Vidal, Alejandra Sapolinski, Alejandro Maiche, Gaston AresAbstract: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.

The Impact of Menu Label Design on Visual Attention, Food Choice and Recognition: An Eye Tracking Study
Journal of Sensory Studies, 2016Co-Authors: Sophie Reale, Stuart W. FlintAbstract:Nutritional Labeling on menus has been found to promote informed food choices and reduce information asymmetry between manufacturers and consumers. However, lack of attention to nutritional Labels limits their effectiveness. This study manipulated the way in which nutritional information was provided on menus in aim of enhancing visual attention to the most health relevant information. A between-subject Design was implemented with three experimental conditions (nondirective Label; directive Label; semidirective Label). A total of 84 participants chose meals off a starter, main and desert menu whilst their eye movements were tracked using Tobii eye tracking software. Results showed that the menu Labels did not significantly differ in their attentional gaining properties, however, the use of color and health logos led participants to choose meals containing significantly less calories compared to when nutritional information was presented in black text alone. These findings indicate that nutritional information should be provided in color or as health logos as this has the largest impact on food choice.

the impact of menu Label Design on visual attention food choice and recognition an eye tracking study
Journal of Sensory Studies, 2016Co-Authors: Sophie Reale, Stuart W. FlintAbstract:© 2016 Wiley Periodicals, Inc.Nutritional Labeling on menus has been found to promote informed food choices and reduce information asymmetry between manufacturers and consumers. However, lack of attention to nutritional Labels limits their effectiveness. This study manipulated the way in which nutritional information was provided on menus in aim of enhancing visual attention to the most health relevant information. A between-subject Design was implemented with three experimental conditions (nondirective Label; directive Label; semidirective Label).

These findings indicate that nutritional information should be provided in color or as health logos as this has the largest impact on food choice. Practical Applications: A factor contributing to the rise in obesity prevalence is the obesogenic environment that we live in. The population has become increasingly reliant on convenience foods and dining out which has led to excess calorie consumption. Menu Labeling has been identified as a possible intervention that could be employed by policy makers to guide informed food choices. However, there are calls for further actions and intervention to improve food choice as menu Labeling has had mixed effects on consumer choice and consumption. This study suggests that menu Labeling is a viable option when the nutritional information is presented in a visually salient way. The use of colors and health logos attracts consumer's attention to the most health relevant information which could contribute to efforts in reducing obesity and other illnesses linked to unhealthy consumption.

effectiveness and acceptability of accelerated repetitive transcranial magnetic stimulation rtms for treatment resistant major depressive disorder an open Label trial
Journal of Affective Disorders, 2015Co-Authors: Alexander Mcgirr, Frederique Van Den Eynde, Santiago Tovarperdomo, Marcelo Pio De Almeida Fleck, Marcelo T BerlimAbstract:Background: Major depressive disorder (MDD) is a significant cause of worldwide disability and treatment resistance is common. High-frequency repetitive transcranial magnetic stimulation (HF-rTMS) has emerged as a treatment for MDD, and while efficacious, the daily commitment for typical 4–6 weeks of treatment poses a significant challenge. We aimed to determine the effectiveness and acceptability of an accelerated rTMS protocol for MDD. Methods: In this naturalistic trial, 27 patients with moderate to severe chronic and treatment-resistant MDD were treated with twice-daily HF-rTMS (10 Hz) applied over the left dorsolateral prefrontal cortex for 2 consecutive weeks (60,000 pulses). The primary outcomes were rates of clinical remission and response (16-item Quick Inventory of Depressive Symptomatology post-treatment score r6, andZ50% reduction, respectively). Secondary outcomes were self-reported anxious symptoms, depressive symptoms and quality of life, and dropout rates as a proxy for acceptability. Results: Ten (37.0%) patients met criteria for clinical remission and 15 (55.6%) were classified as responders, with comparable outcomes for both moderate and severe MDD. Clinician-rated improvements in depressive symptoms were paralleled in self-reported depressive and anxious symptoms, as well as quality of life. No patient discontinued treatment. Limitations: This study is limited by short treatment duration that might be lengthened with corresponding improvements in effectiveness, limited duration of follow-up, small sample size, and an open-Label Design requiring randomized controlled replication. Conclusion: An accelerated protocol involving twice-daily sessions of HF-rTMS over the left DLPFC for 2 weeks was effective in treatment-resistant MDD, and had excellent acceptability. Additional research is required to optimize accelerated rTMS treatment protocols and determine efficacy using sham-controlled trials.
