Effects of long-term multidisciplinary inpatient therapy on body composition of severely obese adolescents
OBJECTIVE: To describe the effects of long-term multidisciplinary inpatient therapy on body composition of severely obese adolescents. METHODS: A total of 728 extremely obese adolescents, including 249 boys (aged 15.25±1.56 years) and 479 girls (aged 15.34±1.59 years) received multidisciplinary therapy during a period of 3 to 9 months. The therapy consisted of reduced energy intake, dietetic education, physical exercises and psychological therapy. Body composition was assessed by bioelectrical impedance analysis, and physical capacity was assessed by the multistage cycle ergometer test. Type and duration of each activity were recorded using a daily controlled activity diary. RESULTS: There was a significant decrease (p < 0.05) in body mass (27.84±12.49 kg for boys and 21.60±9.87 kg for girls), body mass index (9.19±3.88 kg/m² for boys and 7.72±3.98 kg/m² for girls) and fat mass. In addition, the percentage of fat free mass increased significantly (p < 0.05) in boys (from 58.8±6.41 to 69.98±7.43%) and in girls (from 51.86±4.96 to 60.04±5.65%). CONCLUSION: Long-term multidisciplinary approach allows significant reduction in severe obesity, preserving growth and percentage of fat free mass.OBJETIVO: Descrever os efeitos da terapia multidisciplinar de longo prazo sobre a composição corporal de adolescentes obesos severos internados. MÉTODOS: Um total de 728 adolescentes obesos extremos, incluindo 249 meninos (15,25±1,56 anos) e 479 meninas (15,34±1,59 anos), recebeu terapia multidisciplinar durante um período de 3 a 9 meses. A terapia consistiu de redução da ingestão energética, orientação dietética, exercícios físicos e terapia psicológica. A composição corporal foi analisada pela bioimpedância elétrica, e a aptidão física foi avaliada pelo teste em ciclo ergômetro multiestágios. O tipo e duração de cada atividade foram avaliados através de recordatório diário de atividade física. RESULTADOS: Foi verificada redução significante (p < 0,05) na massa corporal (27,84±12,49 kg para meninos e 21,60±9,87 kg para meninas), índice de massa corporal (9,19±3,88 kg/m² para meninos e 7,72±3,98 kg/m² para meninas) e da gordura corporal. Além disso, a porcentagem de massa magra aumentou significantemente (p < 0,05) nos meninos (de 58,8±6,41 para 69,98±7,43%) e nas meninas (de 51,86±4,96 para 60,04±5,65%). CONCLUSÃO: A terapia multidisciplinar de longo prazo permite reduzir acentuadamente a obesidade severa, preservando o crescimento e a porcentagem de massa magra.Universidade Federal de São Paulo (UNIFESP) Escola Paulista de Medicina Programa de Pós-Graduação em NutriçãoObesity Rehabilitation Centre INSULAUNIFESP Departamento de BiociênciasUNIFESP, EPM, Programa de Pós-Graduação em NutriçãoUNIFESP, Depto. de BiociênciasSciEL

Relação entre contagem de leucócitos, adiposidade e aptidão cardiorrespiratória em adolescentes púberes
Objective To compare the total and differential leukocyte count in obese and normal-weight adolescents, and to verify their possible relations with cardiorespiratory fitness and adiposity indicators. Methods A cross-sectional study conducted with 139 adolescents (107 obese and 32 normal weight) aged between 13 and 18 years. Cardiorespiratory fitness was determined by direct gas analysis during an incremental treadmill test. Total leukocytes and subsets were estimated by flow cytometry. Body composition was assessed by dual-energy X-ray absorptiometry. The t-test for independent samples was used for comparison between groups. The relation between leukocytes, cardiorespiratory fitness and adiposity indicators was verified by Pearson’s correlation and multiple linear regression (adjusted for age and body mass index) tests. Results Obese adolescents had higher leukocyte (8.12±2.36u/L x 103; p=0.001), neutrophil (4.33±1.86u/L x 103; p=0.002), and monocyte (0.70±0.22u/L x 103; p=0.002) counts compared to the levels of normal weight subjects. After the necessary adjustments, cardiorespiratory fitness had a negative association with leukocytes, neutrophils, and monocytes in boys. Conclusion Obese adolescents had higher total and differential leucocyte count when compared to normal weight individuals. We also observed a weak positive association between adiposity and total leukocyte, monocyte, and neutrophil counts, and in boys, a negative association between cardiorespiratory fitness and total count of leukocytes, monocytes, and neutrophils.Objetivo Comparar a contagem total e diferencial de leucócitos de adolescentes obesos e eutróficos, e verificar suas possíveis relações com a aptidão cardiorrespiratória e indicadores de adiposidade. Métodos Estudo transversal realizado com 139 adolescentes (107 obesos e 32 eutróficos), com idades entre 13 e 18 anos. A aptidão cardiorrespiratória foi determinada por análise direta de gases durante um teste incremental em esteira rolante. As contagens de leucócitos totais e subconjuntos foram estimadas por citometria de fluxo. A composição corporal foi avaliada pelo método de dupla energia de raios X. O teste t para amostras independentes foi utilizado para comparação entre os grupos. A relação entre leucócitos, aptidão cardiorrespiratória e indicadores de adiposidade foi verificada por meio dos testes de correlação de Pearson e regressão linear múltipla (ajustado para idade e índice de massa corporal). Resultados Os adolescentes obesos apresentaram leucócitos (8,12±2,36u/L x 103; p=0,001), neutrófilos (4,33±1,86u/L x 103; p=0,002) e monócitos (0,70±0,22u/L x 103; p=0,002) mais elevados em comparação com os níveis dos eutróficos. Após os ajustes necessários, a aptidão cardiorrespiratória foi negativamente associada com leucócitos, neutrófilos e monócitos em meninos. Conclusão Adolescentes obesos apresentaram maior contagem de leucócitos totais e subpopulações, quando comparados aos eutróficos. Observou-se também uma fraca relação positiva entre adiposidade e leucócitos totais, monócitos e neutrófilos, e em meninos, uma relação negativa entre aptidão cardiorrespiratória e leucócitos totais, monócitos e neutrófilos.Universidade de PernambucoUniversidade Federal de São Paulo (UNIFESP)UNIFESPSciEL
Impact of the COVID-19 pandemic stay at home order and social isolation on physical activity levels and sedentary behavior in Brazilian adults
Objective: To investigate the impact of the coronavirus 2019 pandemic on physical activity levels and sedentary behavior among Brazilians residents aged ≥18 years.
Methods: An online survey was distributed through a social media platform between May 5 and 17, 2020. Participants completed a structured questionnaire in Google Forms, which assessed the physical activity level and sedentary behavior of adults in Brazil during the pandemic.
Results: Age (OR: 0.98; 95%CI: 0.97-0.99), chronic disease (OR: 1.29; 95%CI: 1.03-1.63), physical inactivity before the coronavirus 2019 pandemic (OR: 2.20; 95%CI: 1.78-2.72) and overweight (OR: 1.34; 95%CI: 1.09-1.65) showed higher risk of impact on physical activity levels. Increased sitting time was associated with older individuals (OR: 0.97; 95%CI: 0.96-0.98), inactivity (OR: 1.51; 95%CI: 1.16-1.96), chronic disease (OR: 1.65; 95%CI: 1.23-2.22), higher number of days in social isolation (OR: 1.01; 95%CI: 1.00-1.02) and higher schooling levels (OR: 1.87; 95%CI: 1.26-2.78).
Conclusion: Our results demonstrated that advanced age, chronic disease and physical inactivity before social isolation had a greater risk of impact on reduced physical activity levels and increased sitting time during the coronavirus 2019 disease pandemic
The same storm but not the same boat: Effects of COVID ‐19 stay‐at‐home order on mental health in individuals with overweight
Objective: To describe the effects of stay‐at‐home orders and social distancing during the coronavirus disease (COVID‐19) outbreak on mental health and to compare these outcomes between individuals with normal weight and overweight. Methods: This cross‐sectional study included 1857 Brazilian adults, who were invited through social media to answer an online questionnaire from 5 May 2020 to 17 May 2020. The instrument included questions related to health behaviour, mental health (anxiety, depression, self‐esteem, sadness and stress) and overall health. Overweight was defined as body mass index (BMI) ≥ 25 Kg/m2. Multiple logistic regression was conducted to identify whether overweight is associated with mental health variables. Results: Women reported increased anxiety (36.5% vs 22.2%, P < .01), depression (16.2% vs 8.8%, P < .01), low self‐esteem (19.8% vs 10.6%, P < .01), sadness (17.7% vs 10.2%, P < .01), and stress (29.5% vs 19.3%, P < .01) relative to men. Women with overweight are more likely to report higher feeling of anxiety (OR 1.62, CI 95% 1.22‐2.14), depression (OR 1.79, CI 95% 1.25‐2.55), low self‐esteem (OR 1.82, CI95% 1.28‐2.58) and sadness (OR 1.51, CI 95% 1.08‐2.10), adjusted for age, social isolation days, educational level, chronic diseases, smoke, alcohol intake and physical activity. Conclusion: Women, specially those with overweight are more vulnerable to the deleterious effects of stay‐at‐home orders on mental health during the COVID‐19 pandemic
Effects of different exercise intensities on serum interleukins levels
O presente estudo teve como objetivo analisar os efeitos agudos e de curta duração de duas intensidades de exercício aeróbio sobre a concentração circulante de IL-6 e IL-10. Quinze homens jovens fisicamente ativos (21,0 ± 1,9 anos) foram submetidos a duas sessões de exercício (“crossover”): alta intensidade de exercício (AIE)- (80% VO2pico), e baixa intensidade de exercício (BIE)- (40% VO2pico), com intervalo de sete dias (“Wash out”). Amostras de sangue foram coletadas em tubos com EDTA, antes do exercício (basal), imediatamente após o exercício (agudo) e após 2 h de recuperação passiva. As concentrações séricas de IL-6 e IL-10 foram determinadas com a utilização de kits comerciais de ELISA. Os resultados demonstraram elevação aguda da IL- 6, em resposta ao AIE em relação ao BIE (p < 0,05), enquanto que a IL-10 apresentou maior redução sistêmica aguda para BIE em comparação a AIE (p < 0,05). Não houve diferença na variação das citocinas após 2 h do término do exercício. Conclui-se que ambas as sessões agudas de exercício são capazes de modular a concentração circulante destas citocinas, e que a magnitude das alterações são dependentes da intensidade do esforço.The aim of this study was to analyze the acute and short-term effects of high and low exercise intensities on IL-6 and IL-10. Fifteen young healthy physically active males (21.0 ± 1.9 yrs) were submitted to 2 experimental trials (cross-over) with a 7-dais wash-out: high exercise intensity (80% VO2peak) and low exercise intensity (40% VO2peak) session. Blood samples were collected before exercise (baseline), immediately after exercise (acute), and two hours after the end of the exercise session (2 h). IL-6 and IL-10 circulating levels were determinate by ELISA. The results demonstrated an acute increase in IL-6 levels after high intensity compared to low intensity exercise (p < 0.05), however, IL-10 presented an acute decrease in response to low intensity exercise (p < 0.05). No effects were observed after 2 h of recovery from the session. Thus we conclude that acute exercise sessions are able to modulate the circulating levels of the studies cytokines, and the magnitudes of these changes are dependent of the exercise intensity
Increased Screen Time Is Associated With Alcohol Desire and Sweetened Foods Consumption During the COVID-19 Pandemic
Background: Elevated screen time has been associated with addictive behaviors, such as alcohol and sugar intake and smoking. Considering the substantial increase in screen time caused by social isolation policies, this study aimed to analyze the association of increased screen time in different devices during the COVID-19 pandemic with consumption and increased desire of alcohol, smoking, and sweetened foods in adults.
Methods: A sample of 1,897 adults with a mean age of 37.9 (13.3) years was assessed by an online survey, being composed by 58% of women. Participants were asked whether screen time in television, cell phone, and computer increased during the pandemic, as well as how much time is spent in each device. Closed questions assessed the frequency of alcohol and sweetened food consumption, smoking, and an increased desire to drink and smoke during the pandemic. Educational level, age, sex, feeling of stress, anxiety, depression, and use of a screen device for physical activity were covariates. Binary logistic regression models considered adjustment for covariates and for mutual habits.
Results: Increased television time was associated with increased desire to drink (OR = 1.46, 95% CI: 1.12; 1.89) and increased sweetened food consumption (OR = 1.53, 95% CI: 1.18; 1.99), while an increase in computer use was negatively associated with consumption of alcohol (OR = 0.68, 95% CI: 0.53; 0.86) and sweetened foods (OR = 0.78, 95% CI: 0.62; 0.98). Increased cell phone time was associated with increased sweetened food consumption during the pandemic (OR = 1.78, 95% CI: 1.18; 2.67). Participants with increased time in the three devices were less likely to consume sweetened foods for ≥5 days per week (OR = 0.63, 95% CI: 0.39; 0.99) but were twice as likely to have sweetened food consumption increased during pandemic (OR = 2.04, 95% CI: 1.07; 3.88).
Conclusion: Increased screen time was differently associated with consumption and desire for alcohol and sweets according to screen devices. Increased time in television and cell phones need to be considered for further investigations of behavioral impairments caused by the pandemic
