Anorexia nervosa (AN) and restrained eating behavior (REB) are characterized by reduced food intake to achieve body weight loss. This scope review aimed to describe the existing evidence on the association between anorexia nervosa, restrictive eating behavior and food consumption. Studies with children and adolescents of both sexes of all races and ethnicities were included. Experimental and observational studies, systematic reviews, meta-analysis, case reports or series, conference abstracts, dissertations and theses were also included. The search was conducted in ten electronic databases and gray literature without language restriction on November 14, 2020. Twenty-four studies met the inclusion criteria. Most studies included girls and identified lower intake of calories, fat and certain micronutrients. There was also a higher intake of caffeine, fiber, vegetables, legumes and fruits and a lower intake of low-quality snack, fast food, sweets and foods with high carbohydrate and fat contents. The need to improve the quality of the diet among study participants was also identified. Thus, it is recommended that the evaluation of food consumption be careful to develop effective prevention strategies for the development of AN/REB and minimize nutritional deficiencies in these individuals.
O distanciamento social adotado para controle da COVID-19 obrigou Instituições de Ensino Superior (IES) a aderirem a novas estratégias para realização das atividades acadêmicas e muitas pesquisas passaram a ser realizadas em ambientes virtuais. O objetivo deste artigo é descrever os aspectos metodológicos e principais desafios enfrentados para a execução do projeto COCASa, um estudo de coorte on-line sobre comportamento alimentar e saúde mental de docentes e discentes de IES do Brasil. O estudo foi iniciado em julho de 2020 e acompanhará os participantes por dois anos. Adotou-se amostragem não probabilística estratificada proporcional com a utilização de escalas, de inquérito alimentar e de questões estruturadas elaboradas pela equipe do projeto. Entre os participantes do baseline, 4.074 discentes e 2.210 docentes iniciaram o questionário e, respectivamente, 76,8% e 85,1% finalizaram o preenchimento. Em ambos os grupos, a maior participação foi de mulheres (docentes: 66,7% e discentes: 76,2%) e residentes nas regiões Nordeste (docentes: 37% e discentes: 50,9%) e Sul (docentes: 27,1% e discentes: 22,5%) do Brasil. A pesquisa on-line amplia a possibilidade de recrutamento de participantes e alcança limites territoriais com menor demanda por financiamento. Durante a pandemia da COVID-19, o uso do ambiente virtual tornou-se uma estratégia viável e acessível para a manutenção das atividades de pesquisa, configurando-se como uma provável tendência a ser adotada pela comunidade científica.
O ganho de peso não intencional está emergindo como uma complicação da pandemia da COVID-19. Considerando a popularização no uso de dados da Internet como parte integrante da informática em saúde, os mesmos podem ser úteis na análise e previsão do comportamento humano. Este estudo analisou as tendências de buscas de usuários brasileiros sobre estratégias para perda de peso. Foi conduzido um estudo infodemiológico, retrospectivo e quantitativo, que examinou dados da ferramenta Google Trends Search Application entre março/2020 a agosto/2021. Os resultados revelaram que a busca por temas relacionados à perda de peso foi expressiva durante os 17 meses pesquisados, em quase todo o país. Os estados que mais se destacaram nas buscas foram Acre, Piauí e Santa Catarina. Em contrapartida, os usuários do Amazonas, Distrito Federal, Mato Grosso, Mato Grosso do Sul e Rio de Janeiro demonstraram menor interesse na temática abordada. As estratégias de emagrecimento com maior popularidade foram dieta e jejum, enquanto exercício físico e remédios para emagrecer apresentaram baixos volumes relativos de buscas (VRBs). Visando a investigação dos demais indicadores e termos de interesse em saúde, novos estudos sobre o tema são necessários para que possam auxiliar na compreensão do cenário corrente e futuro, em âmbito nacional e global, para as questões que envolvem alimentação e nutrição veiculadas na internet.
Antioxidants are compounds associated with delayed aging and the prevention of cancer and inflammatory diseases. These substances can be lost during food processing. Therefore, this work sought to quantitatively characterize the content of bioactive compounds in kale after different treatments and to explore the data generated using principal component analysis (PCA). The analyzes of the total phenolic contents were performed by the Folin-Ciocalteu method and the antioxidant activity were performed by the DPPH and FRAP methods. The graphs of the scores showed that the total phenolics were grouped according to the part of the kale and the solvent used for the extraction, while the graph of the loading showed the influence of the heat treatment in the extraction. It is concluded that the amount of total phenolics contents and antioxidant activity varies depending on the extraction solvent, parts of the vegetable and heat treatment and that this favored its extraction.
We investigated the prevalence of body image dissatisfaction (BID) and associated factors among professors and undergraduate students in Brazil during the COVID-19 pandemic. Using Stunkard’s Figure Rating Scale, BID was analyzed in a sample of 2,220 adults. The independent variables were sociodemographic, lifestyle, mental health symptoms, COVID-19-related factors, disordered eating, experience of weight stigma, and weight change concerns. We used a multinomial logistic regression analysis. The overall prevalence of BID was 82.5% (69.0% due to excess weight), with more professors dissatisfied by excess weight than undergraduate students (78.9% vs. 61.2%, p < 0.001). In the adjusted model, being a young adult (PR, 1.201, 95% CI: 1.128; 1.279), married or in a stable union (PR, 1.088, 95% CI: 1.027; 1.152), reporting of binge eating episode (PR, 1.120, 95% CI: 1.068; 1.173), concern about weight gain (PR, 1.394, 95% CI: 1.310; 1,483), and experience of excess weight stigma (PR, 1.193, 95% CI: 1.141; 1.248) increased the prevalence of BID due to excess weight. While males (PR, 1.578, 95% CI: 1.328; 1.875), moderate to severe depressive symptoms (PR, 1.217, 95% CI: 1.011; 1.465), the concern of losing weight (PR, 1.494, 95% CI: 1.221; 1.830), and experience of low weight stigma (PR, 2.620, 95% CI: 2.093; 3.280) increased the prevalence of BID due to low weight. Different factors associated with BID were observed between students and professors. Bearing in mind the complexity of body image, it is essential to consider different public health interventions and the COVID-19 pandemic’s influence on reducing BID among Brazilian adults, especially susceptible groups.
