Background: Prehabilitation is a strategy used aiming to reduce the risk factors and complications of surgery procedures, but there is no consensus on the effectiveness of supervised physical exercise and its optimal prescription during this phase. Objectives: To determine the effects of exercise prehabilitation on body composition, functional capacity and quality of life in candidates for bariatric surgery. Search methods: A search was conducted in PubMed, Web of Science, SciELO, Scopus, MEDLINE and CINAHL. Selection criteria: Only randomized clinical trials that examined the effectiveness of supervised physical exercise were included. The main outcomes were body composition, functional capacity, quality of life and surgical outcomes. Data collection and analysis: Two researchers independently selected the literature, extracted the data and evaluated the risk of bias. A third researcher was consulted when a consensus was not reached. The risk of bias was assessed by the tool recommended by the Cochrane Collaboration, the quality of the evidence by GRADE, and to analyze the effects of prehabilitation on the primary objectives, RevMan software, version 5.3 was used. Main results: The search resulted in 4550 articles, of which 22 met the eligibility criteria, leaving 5 articles selected for this review. One article was assessed as a high bias risk and four as an uncertain risk, which included 139 candidates for bariatric surgery. Most of the studies evaluated the body composition, functional capacity and quality of life; none reported surgical outcomes. Conclusions: Supervised physical exercise has positive effects on the body composition, functional capacity and quality of life; there was no evidence for surgical outcomes, which opens up a field of study for future research of this population.

This research aims to summarize the process and results of the 2022 Report Card on Physical Activity for Brazilian children and adolescents. A group of experts led by 10 PhD researchers gathered the best possible evidence on physical activity indicators. The Report Card Brazil 2022 included the top 10 indicators of physical activity and sleep, obesity, and poor mental health variables, which made up four dimensions: (I) Daily Behaviors; (II) Settings and Sources of Influence; (III) Government Strategies and Investments; and (IV) Health Outcomes. Comprehensive searches, including peer-reviewed and gray literature searches, were performed for each indicator. Data were considered from systematic reviews, local and national surveys, websites, and official information from the Brazilian Federal Government. Grades from the indicators ranged from F (Active Play) to B (School). In addition, the results found for each indicator were Overall Physical Activity (D), Organized Sport Participation (C−), Active Transportation (C), Sedentary Behaviors (D), Sleep (C), Family and Peers (C−), Community and Environment (C), Government (D+), Physical Fitness (D+), Obesity (11.7%), and Poor Mental Health (37.8%). Successfully strategies for increasing physical activity among Brazilian children and adolescents should look at the different indicators presented in this report.

The epidemic of obesity worldwide has been recognized as a very important challenge. Within its complexity, the identification of higher-risk patients is essential, as it is unsustainable to offer access to treatment to all people with obesity. Several new approaches have recently been presented as important tools for risk stratification. In this research, we applied several of these tools in a cross-sectional study involving adults with obesity classes I, II, III, and super-obesity. The participants had their cardiometabolic risk profiles assessed. The study included adults with obesity aged 18 to 50 years (n = 404), who were evaluated using anthropometric, body composition, hemodynamic, physical fitness, and biochemical assessments. These variables were used to identify the prevalence of risk factors for cardiometabolic diseases according to the classes of obesity by gender and age group. The results showed high prevalence of risk factors, especially among the upper classes of obesity (BMI > 35 kg/m²) using single parameters as the waist circumference, with almost 90% above the cut-off point. For smaller numbers such as Glycated Hemoglobin, however, the prevalence was around 30%. Indexes such as the atherogenic index of plasma (AIP) had the highest prevalence, with 100% of the male participants identified as being at increased risk for cardiovascular disease.

OBJETIVO: Traduzir para a língua portuguesa e adaptar o conteúdo do questionário de avaliação dos estágios de prontidão para mudança do comportamento alimentar e de atividade física proposto por Sutton et al para a aplicação em adolescentes, além de verificar a consistência interna e a reprodutibilidade da nova versão do instrumento. MÉTODOS: A validação de conteúdo foi realizada por um grupo multiprofissional, foi consultado após a tradução e re-tradução do instrumento com o intuito de gerar uma versão coerente, seguida da adaptação cultural realizada por meio de escala Likert, que objetivou analisar a clareza e a relevância, avaliada pelos adolescentes para cada uma das afirmações. A reprodutibilidade e a consistência interna foram analisadas pelo preenchimento do questionário por 32 adolescentes obesos de ambos os sexos, ingressantes em programa de tratamento multiprofissional da obesidade, com idade média de 13,5 (±1,6) anos e peso médio de 86,1kg (±18,8). Para avaliar a consistência interna, aplicou-se o coeficiente Alpha de Cronbach e, para a reprodutibilidade, os coeficientes de correlação de Pearson, Spearman e intraclasse, além do teste t. RESULTADOS: Os resultados revelaram alta reprodutibilidade do instrumento e, no que diz respeito à consistência interna, foram demonstrados bons índices de confiabilidade para todos os domínios, tendo em vista que todos eles apresentaram valores superiores ou bem próximos a 0,70. CONCLUSÕES: O questionário apresentou boa consistência interna e reprodutibilidade para avaliar o estágio de prontidão de mudança do comportamento alimentar e de atividade física em adolescentes obesos. Contudo, para que a validade externa do instrumento seja confirmada, é oportuno que outros estudos sejam realizados.
