“…For example, in our cohort, the prevalence of obesity among adolescents was 5.2%, a value comparable to that found in a recent systematic review performed to investigate the prevalence of paediatric obesity in Brazil 40 . On the other hand, the prevalence of around 0.5% for children younger than 10 years is much lower than the prevalence of around 3% found in this systematic review 40 . Therefore, although age was not a risk factor for death among children with obesity in our model, we cannot rule out some impact on this finding due to the underestimation of obesity in young children in our cohort.…”

“…In this sense, we must point out that it is certainly more difficult to assess the issue of obesity in young children compared with older children in an epidemiological database such as SIVEP‐Gripe. For example, in our cohort, the prevalence of obesity among adolescents was 5.2%, a value comparable to that found in a recent systematic review performed to investigate the prevalence of paediatric obesity in Brazil 40 . On the other hand, the prevalence of around 0.5% for children younger than 10 years is much lower than the prevalence of around 3% found in this systematic review 40 .…”

Background: Obesity is a well-recognized risk factor for critical illness and death among adult patients with SARS-CoV-2 infection.Objective: This study aimed to characterize the clinical outcomes and risk factors of death related to obesity in a cohort of hospitalized paediatric patients with COVID-19. Methods:We performed an analysis of all paediatric patients with obesity and COVID-19 registered in SIVEP-Gripe, a Brazilian nationwide surveillance database, between February 2020 and May 2021. The primary outcome was time to death, which was evaluated by using cumulative incidence function.Results: Among 21 591 hospitalized paediatric patients with COVID-19, 477 cases (2.2%) had obesity. Of them, 71 (14.9%) had a fatal outcome as compared with 7.5% for patients without obesity (hazard ratio [HR] = 2.0, 95% confidence interval[CI] 1.59-2.53, p < 0.001). After adjustment, the factors associated with death among patients with obesity were female gender (HR = 2.8, 95% CI 1.70-4.61), oxygen saturation < 95% (HR = 2.58, 95% CI 1.38-4.79), presence of one (HR = 1.91, 95% CI 1.11-3.26), and two or more comorbidities (HR = 4.0, 95% CI 2.21-7.56).Conclusions: Children and adolescents with obesity had higher risk of death compared with those without obesity. The higher risk of death was associated with female gender, low oxygen saturation at admission, and presence of other comorbidities.

“…Before the COVID-19 pandemic, the main causes of deaths in the country were cancer and cardiovascular disease, which are directly linked to obesity ( 41 , 42 ). The prevalence of obesity has been dramatically increasing in the country, with 12% of the youth population, as well as 20% of adults and 21% of older adults being considered obese in Brazil ( 43 , 44 ). In large part, this scenario is due to sedentary lifestyles ( 45 ).…”

Background: The Physical Activity Readiness Questionnaire for Everyone (PAR-Q+) is the international standard for pre-participation risk stratification and screening. In order to provide a practical and valid screening tool to facilitate safe engagement in physical activity and fitness assessments for the Brazilian population, this study aimed to translate, culturally adapt, and verify the reproducibility of the evidence-based PAR-Q+ to the Brazilian Portuguese language.Method: Initially, the document was translated by two independent translators, before Brazilian experts in health and physical activity evaluated the translations and produced a common initial version. Next, two English native speakers, fluent in Brazilian Portuguese and accustomed to the local culture, back-translated the questionnaire. These back translations were assessed by the organization in charge of the PAR-Q+, then a final Brazilian version was approved. A total of 493 Brazilians between 5 and 93 yr (39.9 ± 25.4 yr), 59% female, with varying levels of health and physical activity, completed the questionnaire twice, in person or online, 1–2 weeks apart. Cronbach's alpha was used to calculate the internal consistency of all items of the questionnaire, and the Kappa statistic was used to assess the individual reproducibility of each item of the document. Additionally, the intraclass correlation coefficient and its 95% confidence interval (CI) were used to verify the general reproducibility (reliability) of the translated version.Results: The Brazilian version had an excellent internal consistency (0.993), with an almost perfect agreement in 93.8% of the questions, and a substantial agreement in the other 6.2%. The translated version also had a good to excellent total reproducibility (0.901, 95% CI: 0.887–0.914).Conclusion: The results show this translation is a valid and reliable screening tool, which may facilitate a larger number of Brazilians to start or increase physical activity participation in a safe manner.

“…According to a national telephone survey carried out in Brazilian state capitals in 2019, the prevalence of excess weight was 75.7% [ 12 ]. The problem of excess weight is not exclusive to the adult population, as the prevalence in children and adolescents is also increasing [ 13 , 14 ].…”

Background This review aimed to estimate the time-trend prevalence of excess weight, overweight and obesity in the Brazilian adult population, from the 1970s–2020, through systematic review and meta-analysis (Protocol: CRD42018091002). Methods A search for articles was conducted in the databases MEDLINE, EMBASE, Scopus, and LILACS up to June 2021. Studies that assessed excess weight, overweight and obesity in the adult population were eligible. Two authors selected studies, collected data and assessed the methodological quality of the studies. The primary outcomes were the prevalence of excess weight, overweight, and obesity by sex and period of years. Pooled prevalence and 95% confidence intervals (CIs) were calculated in the meta-analysis of the random effects model. Heterogeneity (I2) was investigated by meta-regression and publication bias was investigated by Egger’s test. Results A total of 7,938 references were identified in the search strategies, of which eighty-nine studies and nine national surveys, conducted from 1974–2020, were included in the meta-analysis. The pooled prevalence of excess weight in Brazilian adults increased from 33.5% (95% CI: 25.0; 42.6%) in 1974–1990 to 52.5% (95% CI: 47.6; 57.3%) in 2011–2020. The pooled prevalence of overweight in Brazilian adults was 24.6% (95% CI: 18.8; 31.0%) from 1974–1990 and 40.5% (95% CI: 37.0; 43.9%) from 2011–2020. The pooled prevalence of obesity in Brazilian adults increased by 15.0% from 1974–1990 to 2011–2020. The increases were observed for both men and women in almost all periods. The prevalence of excess weight and obesity remained higher among women in all periods. Conclusions A continuous increase in the prevalence of excess weight, overweight and obesity were observed over the years. The prevalence of excess weight affected half of Brazilian adults in the period from 2011–2020 and both sexes.
