Objetivo: Comparar o tempo necessário para realizar escolhas alimentares com diferentes modelos de rotulagem nutricional frontal entre adultos brasileiros. Métodos: Foram realizadas entrevistas com 150 participantes, que foram orientados a escolher o produto mais saudável entre dois alimentos, sendo apresentados oito pares de imagens. Um dos produtos de cada par apresentava advertências (alto em açúcares, sódio ou gordura saturada), testados em formatos diferentes de acordo com o grupo no qual o indivíduo era alocado: lupa, octógono, círculo, triângulo e semáforo. Foram contabilizados o número de acertos do produto mais saudável em cada par e o tempo para escolha correta do produto mais saudável. Resultados: Observou-se menor número de acertos do produto mais saudável entre os pares com semáforo, em comparação com qualquer outro modelo (p<0,001), sendo este também o formato no qual se observou maior tempo necessário para escolher corretamente o produto mais saudável (p<0,001). Não foram observadas diferenças significativas entre os demais formatos. Na análise individual dos produtos, o círculo teve melhor desempenho, sendo observado tempo significativamente menor para escolhas corretas em sete dos oito produtos. Conclusão: Para apoiar escolhas alimentares saudáveis, indica-se o uso de qualquer um dos formatos testados para a rotulagem nutricional frontal, exceto o do semáforo. O círculo aparenta ser uma boa opção para reduzir o tempo do consumidor frente a escolhas saudáveis. ; Objective: to compare the time Brazilian adults required to make food choices with different models of front-of-pack nutrition labeling. Methods: Interviews were conducted with 150 participants, who were instructed to select the healthiest product between two foods, with eight pairs of images presented. One of the products in each pair had warnings (high in sugars, sodium, or saturated fat), evaluated in different formats according to the group in which the individual was allocated: magnifying glass, octagon, circle, triangle, and traffic light. The number of correct answers for the healthiest product in each pair and the time to correctly select of the healthiest product were measured. Results: A lower number of correct answers for the healthier product among the pairs occurred with traffic lights than with any other model (p <0.001), which is also the format in which the longest time was necessary to correctly select the healthiest product (p < 0.001). There were no significant differences between the other formats. In the individual analysis of the products, the circle performed better, with significantly less time required to make the correct choices in seven of the eight products. Conclusion: To support healthy food choices, any of the tested formats for frontal nutrition labeling are indicated, except for the traffic light. The circle appears to be a good option to reduce consumer's time to select healthy choices.

The present article aims to describe and discuss the actions implemented from 2014 to 2018 at the federal level in the context of the Intersectoral Strategy to Prevent and Control Obesity issued by the Brazilian federal government. The goal of the Intersectoral Strategy is to prevent and control obesity based on six action plans: 1) availability and access to adequate and healthy foods; 2) education, communication, and information; 3) promotion of healthy lifestyles in specific environments/territories; 4) food and nutrition surveillance; 5) comprehensive care for individuals presenting obesity in the health care network; and 6) regulation and control of the quality and harmlessness of food. To gather information, semi-structured questionnaires were submitted to representatives from the ministries of Education, Health, Planning, Citizenship, and Agrarian Development. The actions implemented in the period were described in terms of the six action plans. Positive results were achieved through the shared management model adopted, even though many challenges still remain. The agenda for action proposed in the Intersectoral Strategy is attuned to the Brazilian context, and intersectoral management was still in place until the writing of the present article.
