    COVID-19 sequelae are varied, and whether they are temporary or permanent is still unknown. Identifying these sequelae may guide therapeutic strategies to improve these individuals' recovery. This prospective cohort aimed to assess body composition, cardiopulmonary fitness, and long-term symptoms of overweight individuals affected by COVID-19. Participants (n = 90) were divided into three groups according to the severity of acute COVID-19: mild (no hospitalization), moderate (hospitalization, without oxygen support), and severe/critical cases (hospitalized in Intensive Care Unit). We assessed body composition with a tetrapolar multifrequency bioimpedance, hemodynamic variables (heart rate, blood pressure, and peripheral oxygen saturation-SpO2) at rest, and the Bruce test with direct gas exchange. Two assessments with a one-year interval were performed. The most prevalent long-term symptoms were memory deficit (66.7%), lack of concentration (51.7%), fatigue (65.6%), and dyspnea (40%). Bruce test presented a time effect with an increase in the distance walked after 1 year just for severe/critical group (p < 0.05). SpO2 was significantly lower in the severe/critical group up to 5 min after the Bruce test when compared to the mild group, and diastolic blood pressure at the end of the Bruce test was significantly higher in the severe/critical group when compared to mild group (p < 0.05; for all comparisons). A time effect was observed for body composition, with increased lean mass, skeletal muscle mass, fat-free mass, and lean mass just for the severe/critical group after 1 year (p < 0.05). Cardiopulmonary fitness parameters did not differ among the groups, except for respiratory quotient with higher values for the severe/critical group when compared to itself after 1 year. All COVID-19 patients might present long-term sequelae, regardless of the acute disease severity. Reassessing and identifying the most prevalent long-term sequelae are essential to perform more precise health promotion interventions.

    Introduction: Obesity in adolescence is associated with severe health complications. Objective: To analyze possible associations among body mass index (BMI), body composition, and biochemical profiles of overweight or obese adolescents. Methods: The study was carried out between 2017 and 2020 and included 132 adolescents aged 10 to 18 years. The following variables were analyzed: BMI, fat-free mass (FFM), body fat mass (BFM), skeletal muscle mass (SMM), body fat percentage (%BF), waist-to-hip ratio (WHR), lean mass index (LMI), fat mass index (FMI), and fat-to-lean mass ratio (FMR), as well as total cholesterol (TC), high-density lipoprotein (HDL-c), low-density lipoprotein (LDL-c) and glutamic-oxaloacetic transaminase (TGO). Statistical analyses were performed using SPSS® version 20.0, considering p<0.05 as significant. Results: Higher values were identified for height, LBM, FFM, and SMM in the male group. On the other hand, higher values were identified for the %BF and FMI in the female group. The female, male, and general groups showed significant correlations between BMI and FMR (r = 0.69, 0.74, and 0.69, respectively), BMI and FFM (r = 0.44, 0.67, and 0.49, respectively), BMI and SMM (r = 0.44, 0.68, and 0.50, respectively), and BMI and %BF (r = 0.40, 0.54, and 0.47, respectively). In the general group, BMI and HDL levels were correlated (r = −0.18; p=0.04). The BFM and WHR showed a predictive effect for TC; WHR and %BF showed a predictive effect for LDL concentrations, and %BF had a predictive effect for TGO (p<0.05). Conclusions: It was possible to verify that BMI, body composition, and biochemical measures show an interrelationship between them, such as with a worsening of anthropometric and body composition indicators associated with worst biochemical parameters, e.g., lower HDL-c and higher TC, LDL-c, and TGO. Thus, public policies are indispensable for combating obesity and related comorbidities in the early phases of life.

    Overweight in adolescents: a possible association between sleep quality and eating behavior according to sex
    (2023-07-26) Almeida, Letícia; Nanuncio Capucho, Virgínia Benedetti; de Souza Marques, Déborah Cristina; Costa Ferreira, Willian; Ferrari Silva, Bruno; Valdés-Badilla, Pablo; Magnani Branco, Braulio Henrique
    Introduction: Obesity is a multifactorial disease affecting adolescent sleep quality and binge eating. Objective: to analyze adolescents’ sleep quality and possible binge eating according to sex and nutritional status. Methods: 108 adolescents (n = 51 male and n = 57 female) aged between 10 to 18 years were recruited. Body composition was assessed by bioelectrical impedance, in which the following variables were collected: body weight, body fat percentage, and resting metabolic rate. The Z-score was calculated and classified by height and weight as eutrophic and overweight. Subsequently, the adolescents answered the Brazilian version of the Pittsburgh Sleep Quality Index (PSQI) questionnaire and the binge eating - Periodic Eating Compulsion Scale (BES) questionnaire to assess possible periodic eating compulsion. Results: In the anthropometric analysis, male adolescents showed greater height (p<0.0001), body weight (p<0.05), resting metabolic rate (p<0.0001), total body water (p<0.0001), lean mass (p<0.0001), fat-free mass (p<0.0001) and skeletal muscle mass (p= 0.01) compared to female adolescents. However, female adolescents had a higher body fat percentage when compared to male adolescents (p= 0.01). In addition, overweight adolescents of both sexes had higher BES scores compared to eutrophic ones (p<0.05), with higher scores for females compared to males (p<0.05). However, no differences were observed between overweight and eutrophic individuals of both sexes for PQSI (p>0.05). Conclusion: Binge eating was identified in both sexes and may be related to poor sleep quality.
