RESUMO
INTRODUCTION: Heart failure (HF) is among the leading causes of morbidity and mortality worldwide. Several conditions trigger left ventricular chronic pressure or volume overload, hypertrophy, systolic and diastolic dysfunction, leading to cardiac remodeling and a rapid progression toward HF. Therapeutic interventions elicit reverse remodeling (RR), a highly variable myocardial response that ranges from none to total ventricular structural/functional recovery. However, HF patients present several comorbidities and medications that mask a comprehensive molecular knowledge of RR and hinder the identification of potential biomarkers of its progression or prognosis. Therefore, instead of using this heterogeneous population or even animal models to understand myocardial remodeling, we propose studying pregnancy-induced cardiovascular remodeling and postpartum-induced RR. OBJECTIVES: To assess cardiovascular functional and structural adaptations during pregnancy and in postpartum, characterizing the associated molecular changes; as well as to explore the impact of hypertension, obesity and diabetes on these processes. METHODS: We will perform echocardiography and assess endothelial function and arterial stiffness (EndoPAT® and pulse wave velocity, respectively) and assess potential markers of remodeling and RR using plasma and urine samples from pregnant women. To translate to a HF context, we will determine the impact of risk factors (hypertension, obesity and diabetes) by studying subgroups of pregnant women with these comorbidities. RESULTS: Not applicable. CONCLUSION: We are convinced that understanding the impact of these comorbidities in such a homogeneous population, such as pregnant women, provides a valuable model to unveil the most relevant pathologic and often masked signaling pathways underlying cardiac remodeling and incomplete RR in a heterogeneous population, such as HF patients. Moreover, we expect to identify potential novel biomarkers of RR progression/prognosis more easily.

OBJECTIVE: To verify the thermoregulatory and perceptual responses of obese and lean girls, either fit or unfit, exercising in the heat at a similar rate of metabolic heat production per unit body mass. METHODS: A total of 34 pubescent girls were allocated in four groups: 12 obese fit, 9 obese unfit, 5 lean fit, and 8 lean unfit. The obese groups (13.2±1.4 years, 40.5%±5.8% fat by DXA) differed in their aerobic fitness (VËO2peak 76.0±8.1 vs. 56.6±5.8mL.kgmusclemass-1.min-1), as well as the lean groups (13.1±1.6 years, 24.0%±4.8% fat) (VËO2peak 74.5±2.9 vs. 56.2±5.0mL.kgmuscle mass-1min-1). Girls cycled two bouts of 25min with a 10min rest in between, at â¼5.4W.kg-1 in the heat (36°C and 40% relative humidity) and they were kept euhydrated. Rectal and skin temperatures and heart rate were measured every 5min. Perceptual responses were evaluated throughout the exercise. RESULTS: Initial rectal temperature was higher in the obese subjects compared to the lean subjects (37.5±0.3 and 37.2±0.3°C). No difference was observed among the girls whom were obese (eight fit or unfit) and lean (also fit or unfit) throughout the exercise in rectal temperature (37.6±0.2, 37.5±0.3, 37.5±0.3, 37.4±0.3°C, respectively), skin temperature (34.8±0.8, 35.1±1.0, 34.4±0.9, 35.2±0.9°C), and heart rate (128±18; 118±12, 130±16, 119±16beatsmin-1). No differences were observed in perceptual responses among groups. CONCLUSION: Regardless of the adiposity or aerobic fitness, pubescent girls had similar thermoregulatory and perceptual responses while cycling in the heat at similar metabolic heat production.

BACKGROUND: Obesity causes various difficulties in intubation and ventilation, which are confronted due to increased fat tissue in the upper airway and diminished compliance in the chest wall. Videolaryngoscopes and Intubating Laryngeal Mask Airway (ILMA) are good options as recommended by the American Society of Anesthesologists (ASA) difficult airway guidelines. We aimed to compare ILMA and Airtraq (a channeled videolaryngoscope) in obese patients. METHODS: Eighty patients with ASA physical status I-III, aged between 18 and 65 years and with a body mass index greater than 35 kg.m-2, who were undergoing elective surgery requiring orotracheal intubation, were included in the study. Patients were intubated with one of the devices cited. RESULTS: There was no difference between the number of intubation attempts, insertion times and need for optimisation manoeuvres of Airtraq and ILMA. The intubation with Airtraq was accomplished in a shorter period of time than in that in the ILMA group (29.9±22.1s vs. 50.7±21.2s; p<0.001). A significant difference was found when the times of total intubation were compared (29.9±22.1s vs. 97.4±42.7s; p<0.001). The mean arterial pressure statistically increased after device insertion in the ILMA group (p<0.05). CONCLUSIONS: Airtraq appears to be superior to ILMA in obese patients, with a total of time intubation of less than 60 seconds and with low mean arterial pressure changes. However, ILMA is still a useful tool that provides both ventilation and intubation throughout the whole intubation process.

OBJECTIVE: To identify factors that contribute to the increased susceptibility and severity of COVID-19 in obese children and adolescents, and its health consequences. SOURCES: Studies published between 2000 and 2020 in the PubMed, MEDLINE, Scopus, SciELO, and Cochrane databases. SUMMARY OF FINDINGS: Obesity is a highly prevalent comorbidity in severe cases of COVID-19 in children and adolescents; social isolation may lead to increase fat accumulation. Excessive adipose tissue, deficit in lean mass, insulin resistance, dyslipidemia, hypertension, high levels of proinflammatory cytokines, and low intake of essential nutrients are factors that compromise the functioning of organs and systems in obese individuals. These factors are associated with damage to immune, cardiovascular, respiratory, and urinary systems, along with modification of the intestinal microbiota (dysbiosis). In severe acute respiratory syndrome coronavirus 2 infection, these organic changes from obesity may increase the need for ventilatory assistance, risk of thromboembolism, reduced glomerular filtration rate, changes in the innate and adaptive immune response, and perpetuation of the chronic inflammatory response. CONCLUSIONS: The need for social isolation can have the effect of causing or worsening obesity and its comorbidities, and pediatricians need to be aware of this issue. Facing children with suspected or confirmed COVID-19, health professionals should 1) diagnose excess weight; 2) advise on health care in times of isolation; 3) screen for comorbidities, ensuring that treatment is not interrupted; 4) measure levels of immunonutrients; 5) guide the family in understanding the specifics of the situation; and 6) refer to units qualified to care for obese children and adolescents when necessary.

Morbid obesity is associated with various pathophysiological changes which affect the outcome of anesthesia and surgery. So it's challenging to give anesthesia to such patients. We present a 59-year-old adult morbidly obese, hypertensive, diabetic female with hypothyroidism operated for proximal humerus fracture and now presented with non-union of fracture, requiring percutaneous injection of bone marrow aspirate from the iliac crest to the site of non-union. The patient was extremely anxious and refused to undergo the procedure under local anesthesia or sedation and demanded anesthesia. Given her comorbidities general anesthesia (GA) was avoided and the procedure was accomplished using Ultrasound (USG) guided Transversus abdominis plane (TAP) block and Lateral Femoral Cutaneous Nerve (LFCN) block for the bone marrow aspirate from the iliac crest and Intercostobrachial nerve block (T2) was given to prevent pain while injecting the aspirate into the non-union site. Dexmedetomidine and ketamine were given for deep level sedation and analgesia. TAP block and LFCN block is generally used for post-op analgesia but can be also used for surgical anesthesia instead of General anesthesia in specific scenarios. Its perioperative application and its potential use instead of GA have been discussed.

OBJECTIVE: To estimate the mean age at menarche and its association with nutritional status in Brazilian adolescents. METHODS: The study sample included female adolescents aged 12-17 who participated in a multicenter, school-based, country-wide, cross-sectional study entitled The Study of Cardiovascular Risk in Adolescents (Estudo de Riscos Cardiovasculares em Adolescentes [ERICA]). Mean and median ages at menarche in Brazil were estimated. The association of age at menarche with sociodemographic data and nutritional status were described as means and their respective 95% confidence intervals. Survival analysis was used to assess the age at menarche according to nutritional status categories and the log-rank test was used to compare the medians. Bivariate and multivariate analyses were performed using Cox regression to verify the association between menarche and other variables. RESULTS: A total of 73,624 students were evaluated, comprising 40,803 girls, of whom 37,390 reported menarche at a mean age of 11.71 years and a median of 12.41 years. Median age at menarche was lower in overweight and obese girls (p<0.001). The multivariate analysis showed that excess weight (HR=1.28; 95% CI 1.21-1.36; p<0.001) and studying in a private school (HR=1.06; 95% CI 1.02-1.10; p=0.003) were associated with menarche. CONCLUSIONS: This is a pioneering study in Brazil with national and regional representativeness to estimate the mean and the median age of occurrence of menarche. Adolescents with excess weight had an earlier menarche than their peers, even after adjustment for confounding factors.

OBJECTIVES: This study aimed to assess the quality of systematic reviews on prevention and non-pharmacological treatment of overweight and obesity in children and adolescents. DATA SOURCE: A search was done in electronic databases (Medline via PubMed, Web of Science, Scopus, LILACS, the Cochrane Library, and Clinical Trials), including only systematic reviews with meta-analysis. Reviews were selected by two researchers, and a third one solved the divergences. PRISMA statement and checklist were followed. SUMMARY OF DATA: A total of 4574 records were retrieved, including 24 after selection. Six reviews were on obesity prevention, 17 on obesity treatment, and one on mixed interventions for prevention and treatment of obesity. The interventions were very heterogeneous and showed little or no effects on weight or body mass index. Mixed interventions that included dieting, exercise, actions to reduce sedentary behavior, and programs involving the school or families showed some short-term positive effects. Reviews that analyzed cardiovascular risk factors demonstrated significant improvements in the short-term. CONCLUSION: The systematic reviews of interventions to prevent or reduce obesity in children and adolescents generally showed little or no effects on weight or body mass index, although cardiovascular profile can be improved. Mixed interventions demonstrated better effects, but the long-term impact of obesity treatments of children and adolescents remains unclear.

This article presents the results of a quantitative re-search with a descriptive exploratory bias, whose objective was to analyze the perception of 22 Physical Education teachers (18 men and 04 women), working in higher education, about the role of school and Physical Education in controlling overweight and juveni-le obesity. An adapted version of the Perceptions of Youth Obesity and Physical Education Questionnaire was used. The analysis of the data from the categories called perception of youth obesity, role of the school and role of Physical Education allowed inferring that teachers perceive the school as a potential space for the pro-motion of actions, such as the offer of curricular disciplines aimed at controlling the body weight. However, both the school and the teacher and their practice in Physical Education classes should not limit interventions to the treatment and control of juvenile obesity.

RESUMO
OBJECTIVE: Evaluate the association between inflammatory process, adiposity, and vitamins A, D, and E in adolescents, according to gender. METHODS: Cross-sectional study with adolescents aged 12-19 years old of both genders attending public schools in Recife. A questionnaire was used to collect data on socioeconomic level, lifestyle, and food intake of adolescents. Then, an anthropometric evaluation and a blood sampling were performed to analyze serum concentrations of α-1-acid glycoprotein, retinol, ß-carotene, α-tocopherol, and 25-hydroxy-vitamin D. RESULTS: The levels of α-1-acid glycoprotein were higher for abdominal obesity in both genders. Male adolescents with insufficient serum α-tocopherol levels had low levels of α-1-acid glycoprotein (p=0.03) and an increased risk of 25-hydroxy-vitamin D and ß-carotene deficiency in relation to total and abdominal fat; female adolescents had an increased risk of insufficient ß-carotene with abdominal obesity (PR: 1.33; 95% CI: 1.2-1.5). CONCLUSION: Abdominal adiposity implies a higher risk of inflammation and causes different changes to the levels of fat-soluble vitamins according to gender.

Resumo A forma como moldamos e apresentamos socialmente o nosso corpo tem uma extraordinária importância social: a aparência é o nosso primeiro cartão de visita a partir do qual as pessoas nos enquadram e julgam. Esta avaliação acaba por condicionar o nosso quotidiano, desde às nossas oportunidades sociais até às profissionais. Um dos critérios mais importantes para determinar se uma pessoa é saudável e bonita - em Portugal, assim como em muitos outros contextos - é a magreza. Numa sociedade em que a magreza e a perfeição física são ideais a perseguir, este artigo explora através de metodologias qualitativas o impacto do discurso ligado ao problema da obesidade causado pela pandemia de COVID-19 na multiplicação e exacerbação de conflitos relacionados com o corpo em mulheres portuguesas entre os 18 e os 65 anos.
Abstract How we shape and socially present our body has extraordinary social importance: appearance is our first business card by which people frame and judge us. This evaluation ends up conditioning our daily lives, from social to professional opportunities. In Portugal, as in many other contexts, one of the most important criteria for determining whether someone is healthy and beautiful is thinness. In a society where thinness and physical perfection are pursuable ideals, this article explores through qualitative methodologies the impact of the discourse linked to the problem of obesity caused by the COVID-19 pandemic on the multiplication and exacerbation of body-related conflicts in Portuguese women aged 18 to 65.
RESUMO
Resumo Fundamento: A deficiência de testosterona (DT) é uma condição prevalente em nosso meio e ainda muito negligenciada. A hipertensão arterial (HA) é um de seus possíveis fatores associados. Objetivos: Determinar a prevalência de DT em uma população masculina hipertensa e os fatores associados à sua ocorrência, como idade, tempo de diagnóstico de HA, número de classes de anti-hipertensivos, índice de massa corporal (IMC), diabetes, dislipidemia, doença renal crônica (DRC), sintomas positivos de DT (questionário ADAM positivo) e uso de espironolactona. Métodos: Estudo transversal com aplicação do questionário ADAM, e avaliação de dados bioquímicos, clínicos e antropométricos. Os pacientes foram estratificados em grupos de DT e testosterona normal. As variáveis categóricas foram comparadas pelo teste do qui-quadrado e as variáveis contínuas pelo teste de Mann-Witney; as variáveis com significância (p<0,05) foram submetidas à regressão linear multivariada. Resultados: A prevalência de DT foi de 26,8%. Houve associação entre DT e IMC (p=0,0007), mas não houve com idade (p=0,0520), tempo de diagnóstico de HA (p=0,1418), número de classes de anti-hipertensivos (p=0,0732), diabetes (p=0,1112); dislipidemia (p=0,3888); presença de DRC (p=0,3321); uso de espironolactona (p=0,3546) e questionário ADAM positivo (p=0,2483). Conclusões: A prevalência de DT foi alta e houve associação positiva com IMC. A testosterona total (TT) declinou 8,44 ng/dL com o aumento de 1 kg/m2 no IMC e caiu 3,79 ng/dL com o avanço em um ano na idade.
Abstract Background: Testosterone deficiency (TD) is a prevalent condition in our midst and still very neglected. Arterial hypertension (AH) is one of the possible associated factors. Objectives: To determine the prevalence of TD in a hypertensive male population and the factors associated with its occurrence, such as age, time since hypertension diagnosis, number of antihypertensive classes, body mass index (BMI), diabetes, dyslipidemia, chronic kidney disease (CKD), positive symptoms of TD (positive ADAM questionnaire) and use of spironolactone. Methods: Cross-sectional study with administration of the ADAM questionnaire, assessment of biochemical, clinical, and anthropometric data. Patients were stratified into DT and normal testosterone groups. Categorical variables were compared using the chi-squared test and continuous variables using the Mann-Witney test; variables with significance (p<0,05) were analyzed by multivariable linear regression. Results: The prevalence of TD was 26.36%. There was an association between TD and body mass index (BMI) (p=0.0007) but there was no association with age (p=0.0520), time of hypertension diagnosis (p=0.1418), number of classes of antihypertensive drugs (p=0.732), diabetes (p=0.1112); dyslipidemia (p=0.3888); CKD (p=0.3321); use of spironolactone (p=0.3546) or positive ADAM questionnaire (p=0.2483). Conclusions: TD was highly prevalent and positively associated with BMI. Total testosterone (TT) declined by 8.44ng/dL with a one unit increase in BMI and dropped by 3.79ng/dL with a one-year increase in age.
RESUMO
Abstract This article aims to analyse the relationship between physical activity (PA) environment at schools, sex, age, and obesity in children, using a network approach. This is a cross-sectional study, with 1,200 children (8.1±1.0 years old) from eight public schools in the same municipality. Weight and height measurements were assessed to calculate the Body Mass Index (BMI) and classified as healthier weight or overweight. To assess the PA environment at school, a interview with the school´s manager was conducted. The association between the PA environment at school and obesity was tested using a Network Analysis performed on the Jasp software. Positive associations between BMI and Physical Education classes (0.847), physical education teacher (0.349), break duration (0.564), and indoor sports court (0.662) were observed. Negative associations were seen with sex (-0.212) age (-0.387), extracurricular PA (-0.492), and playground (-0.557). Additionally, the centrality indicators highlighted extracurricular PA (1.789) as the variables with the highest betweenness values, and BMI with the highest closeness (2.239) and strength (1.230) values. Extracurricular PA and the presence of playgrounds in school´s environment are associated with healthier weight in low-income children.
Resumo O objetivo deste artigo é analisar a relação entre ambiente de atividade física (AF) nas escolas, sexo, idade e obesidade em crianças, usando uma abordagem de rede. Trata-se de um estudo transversal com 1.200 crianças (8,1±1,0 anos) de oito escolas públicas do mesmo município. Peso e estatura foram avaliadas para cálculo do Índice de Massa Corporal (IMC) e classificadas como peso saudável ou sobrepeso. Para avaliar o ambiente de AF na escola, foi aplicado um questionário por meio de entrevista com o gestor da escola. A associação entre o ambiente de AF na escola e a obesidade foi testada por meio Análise de Redes realizada no software Jasp. Foram observadas associações positivas entre o IMC e as aulas de Educação Física (0,847), professor de educação física (0,349), duração do intervalo (0,564) e quadra poliesportiva (0,662). Associações negativas foram observadas com sexo (-0,212), idade (-0,387), AF extracurricular (-0,492) e playground (-0,557). Adicionalmente, os indicadores de centralidade destacaram a AF extracurricular (1,789) como a variável com o maior valor de intermediação, e o IMC com o maior valor de proximidade (2,239) e força (1,230). A AF extracurricular e a presença de playgrounds no ambiente escolar estão associadas a um peso mais saudável em crianças de baixa renda.
RESUMO
ABSTRACT Background: Obesity is a chronic health condition with a multifactorial etiology, resulting from the interplay of genetic, environmental, and behavioral factors leading to an energy imbalance. Objective: To characterize hospitalizations for bariatric surgeries through the Brazilian Unified Health System (SUS) in the state of Paraná from 2012 to 2022. Methods: This is a descriptive and retrospective study, utilizing a time series design, based on secondary data. Public data from the SUS Hospital Information System for the period from 2012 to 2022 were consulted, focusing on the population of obese patients undergoing bariatric surgery. Results: In Paraná, concerning SUS procedures data from 2012 to 2022, 39,793 hospitalizations for bariatric surgeries were observed. Among the five modalities, Roux-en-Y gastric bypass predominated with 38,849 hospitalizations (97.6%), showing a lower mortality rate. Conclusion: The research highlights a notable variation in costs, emphasizing the importance of economic evaluation. The correlation between obesity and diabetes underscores the complexity of the situation, justifying the superiority of surgical treatment in comorbidity remission. The study reveals a decline in bariatric surgeries in 2020, coinciding with the pandemic, and alerts to the increased vulnerability of obese patients to SARS-CoV-2.
RESUMO Contexto: A obesidade é uma condição crônica de saúde que apresenta etiologia multifatorial. Resulta da combinação de fatores genéticos, ambientais e comportamentais, os quais, quando interagem, levam a um desbalanço energético. Objetivo: Caracterizar as hospitalizações pelo Sistema Único de Saúde (SUS) para realização de cirurgias bariátricas no estado do Paraná, no período de 2012 a 2022. Métodos: Trata-se de um estudo descritivo e retrospectivo, do tipo série temporal, baseado em dados secundários. Foram consultados os dados públicos contidos no sistema de informações hospitalares do SUS, no período de 2012 a 2022. A população analisada foram pacientes obesos submetidos à cirurgia bariátrica. Resultados: No Paraná, com relação aos dados de procedimentos realizados no SUS, no período de 2012 a 2022, foram observadas 39.793 hospitalizações para a realização de cirurgias bariátricas. Dentre as cinco modalidades, houve predomínio da gastroplastia em Y de Roux, com 38.849 hospitalizações (97,6%), com menor taxa de mortalidade. Conclusão: A pesquisa ressalta uma notável variação nos custos, enfatizando a importância da avaliação econômica. A correlação entre obesidade e diabetes evidencia a complexidade da situação, justificando a superioridade do tratamento cirúrgico na remissão de comorbidades. O estudo mostra uma queda nas cirurgias bariátricas em 2020, coincidindo com a pandemia, e alerta para a maior vulnerabilidade de pacientes obesos ao SARS-CoV-2.
RESUMO
Introdução:O estigma relacionado ao peso corporal, presente entre profissionais e estudantes da área da saúde, prejudica a saúde e o cuidado de pessoas com sobrepeso e obesidade, e deve ser combatido. Objetivo:Este artigo visa relatar os resultados obtidos por meio da aplicação de um curso educativo sobre estigma relacionado ao peso corporal e o cuidado em saúde. Métodos:A aplicação ocorreu com 11 profissionais de saúde e teve desenho misto. No componente quantitativo, foi realizada análise estatística dos resultados iniciais e finais obtidos por meio da Escala de Atitudes Antiobesidade (AFAT), com realização de teste t pareado (nível de significância de p ≤ 0,05). No componente qualitativo, foi realizada análise de conteúdo temática de uma atividade final dissertativa sobre ideias que ficaram marcadas a partir do curso. Feedbacksestruturados a respeito da qualidade do material foram preenchidos. Resultados:As análises estatísticas não identificaram alterações entre os valores iniciais e finais da AFAT (p >0,05), com escore geral médio inicial de 0,418 e final de 0,419. Cinco temas emergiram da análise de conteúdo, os quais demonstram aprendizagem quanto à multifatorialidade da obesidade; reconhecimento de implicações interseccionais; compreensão dos impactos do estigma no cuidado em saúde; estímulo ao pensamento crítico; e considerações sobre o curso, no geral, bem avaliado de forma consistente. Conclusão:O instrumento quantitativo não indicou mudança; contudo, as análises qualitativas demonstram que o curso promoveu compreensão ampliada sobre os temas discutidos, bem como a reflexão e a autocrítica das/os profissionais.
Introduction:Weight stigma, present among health professionals and students, harms the health and healthcare of people with overweight and obesity and must be combated. Objective:This article aims to report the results obtained through a test application of an educational course on weight stigma and healthcare. Methods:The test was carried out with 11 healthcare professionals and had a mixed design. In the quantitative component, statistical analysis was carried out on the initial and final results obtained using theAntifat Attitudes Scale (AFAT), with a paired t test (significance level of p ≤ 0.05). In the qualitative component, a thematic content analysis was carried out with data produced in a final dissertation activity about ideas that were highlighted from thecourse. Structured feedback regarding the quality of the material was completed. Results:Statistical analyzes did not identify changes between initial and final AFAT values (p >0.05), with an initial overall average score of 0.418 and final of 0.419. Five themes emerged from the content analysis, which demonstrate learning regarding the multifactorial nature of obesity; recognition of intersectional implications; understanding of impacts of stigma on health care; stimulation of critical thinking; and considerations about the course, overall, consistently well evaluated. Conclusion: The quantitative instrument did not indicate change, however, qualitative analysis indicated that the course promoted expanded understanding of the topics discussed, as well as reflection and self-criticism by professionals.

OBJECTIVE: Evaluate the relationship between body mass index and physical fitness in a cross-sectional sample of Brazilian youth. METHODS: Participants were 3849 adolescents (2027 girls) aged 10-17 years. Weight and height were measured; body mass index was calculated. Physical fitness was evaluated with a multistage 20m shuttle run (cardiovascular endurance), standing long jump (power), and push-ups (upper body strength). Participants were grouped by sex into four age groups: 10-11, 12-13, 14-15, and 16-17 years. Sex-specific ANOVA was used to evaluate differences in each physical fitness item among weight status categories by age group. Relationships between body mass index and each physical fitness item were evaluated with quadratic regression models by age group within each sex. RESULTS: The physical fitness of thin and normal youth was, with few exceptions, significantly better than the physical fitness of overweight and obese youth in each age group by sex. On the other hand, physical fitness performances did not consistently differ, on average, between thin and normal weight and between overweight and obese youths. Results of the quadratic regressions indicated a curvilinear (parabolic) relationship between body mass index and each physical fitness item in most age groups. Better performances were attained by adolescents in the mid-range of the body mass index distribution, while performances of youth at the low and high ends of the body mass index distribution were lower. CONCLUSION: Relationships between the body mass index and physical fitness were generally nonlinear (parabolic) in youth 10-17 years.

OBJECTIVE: To identify factors associated with total sedentary time and screen time in children aged 9-11 years. METHODS: For seven consecutive days, 328 children (51.5% boys) used accelerometers to monitor total sedentary time. Screen time was calculated by the self-reporting method. Individual, family, family environment, and school environment questionnaires were filled out. Body composition was measured using a Tanita scale. RESULTS: The mean sedentary time was 500min/day (boys: 489, girls: 511, p=0.005), and mean screen time was 234min/day (boys: 246, girls: 222, p=0.053). In both genders, factors associated with sedentary time were healthy dietary pattern and moderate-to-vigorous physical activity. In boys, only moderate-to-vigorous physical activity was significant; in girls, the healthy dietary pattern, moderate-to-vigorous physical activity, and transportation to school were significant. As for the screen time, the associated factors were body mass index and healthy dietary pattern (both genders). In boys, the associated factors were body mass index, healthy dietary pattern, and television in the bedroom. In girls, the associated factors were healthy dietary pattern, transportation to school, and physical activity policies or practice at school. CONCLUSION: Several associated factors were identified in the association between total sedentary time and screen time in children; however, only the healthy dietary pattern was common between sedentary time and screen time.

OBJECTIVE: To identify health-related quality of life in adolescents with excess weight and associated factors, such as gender, age, and weight categories. METHOD: A cross-sectional study with collected and secondary data from 276 adolescents aged between 10 and 19 years with overweight and obesity, and whose parents or guardians authorized their participation. Anthropometric data, pubertal development, and the PedsQL 4.0 questionnaire were collected for the health-related quality of life assessment. Categorical data were described as numbers and percentages. For the description of health-related quality of life subscales, medians and the 25th and 75th percentiles were used, as well as the Mann-Whitney test for comparisons between age group, gender, and weight categories. RESULTS: The median health-related quality of life total score was 78.3 (68.5-87.4). The lowest scale was the "emotional score", 65 (50-80). Higher health-related quality of life was found in boys in most of the scores (p<0.05), except for the "school score" (p=0.09). Regarding the age group, the median of the "physical scores" (p=0.03) and "social score" (p=0.02) were significantly lower in the group younger than 14 years. When separated according to weight categories, it was verified that obese adolescents differed significantly in relation to the "physical score" (p=0.00), "school score" (p=0.04), and "total score" (p=0.02) of the health-related quality of life. However, there was no significant difference between the emotional, social, and psychosocial scores. CONCLUSIONS: Adolescents with overweight and obesity show losses in the health-related quality of life and also between the different domains, when separated by age, gender, and weight categories.

OBJECTIVES: The prevalence of obesity is increasing. The aim of this study was to investigate if there is endothelial dysfunction in children with normal or excess weight, and whether the metabolic profile, adipokines, and endothelial dysfunction would be more strongly associated with physical fitness or with physical activity levels. METHOD: Cross-sectional study involving children aged 5-12 years. The evaluation included venous occlusion plethysmography, serum levels of adiponectin, leptin and insulin, lipid profile, physical activity score (PAQ-C questionnaire), and physical fitness evaluation (Yo-Yo test). RESULTS: A total of 62 children participated in this study. Based on the body mass index, 27 were eutrophic, 10 overweight and 25 obese. Triglycerides, LDL cholesterol, HOMA-IR, and leptin were higher in the obese and excess-weight groups compared to the eutrophic group (p<0.01). HDL cholesterol and adiponectin levels were higher in the eutrophic group compared to the obese and excess-weight groups (p<0.01). Flow-mediated vasodilation after hyperemia was higher in the eutrophic group in comparison to obese and excess-weight subjects (p<0.05). There was no difference in the physical activity levels among groups measured by PAQ-C. The Yo-Yo test was significantly associated with HDL cholesterol (rho=-0.41; p=0.01), and this association remained after adjusting for body mass index z-score (rho=0.28; p=0.03). CONCLUSION: This study showed that endothelial dysfunction is already present in obese children, suggesting a predisposition to atherosclerotic disease. Moreover, HDL cholesterol levels were correlated with physical fitness, regardless of body mass index.

Abstract Objectives: to investigate the association between dietary patterns, physical activity, and body phenotypes in adolescents. Methods: this school-based cross-sectional study involved 1,022 adolescents aged ten to 19 years. Dietary patterns and body phenotypes were defined using a principal component analysis. Body phenotype was defined using anthropometry, body composition, biochemistry, sexual maturation, and dietary patterns from 19 food groups, using a food frequency questionnaire. The association between the dietary patterns and body phenotypes was assessed using a linear regression model. Results: five body phenotypes (BP1adiposity, BP2puberty, BP3biochemical, BP4muscular, BP5lipids_biochemical) and five dietary patterns (DP1ultraprocessed_foods, DP2fresh_foods, DP3bread_rice_beans, DP4culinary_preparations, DP5cakes_rice_beans) were identified. There were higher BP_adiposity scores for obese adolescents, but energy expenditure was similar for obese and non-obese adolescents. Physical activity was positively associated with BMI, BP_adiposity, and BP_puberty. We observed a negative association between DP_ultraprocessed_foods and BMI, and a positive association between DP_fresh_food. DP_fresh_foods was positively associated with BP_adiposity; DP_ultraprocessed_foods and DP_culinary_preparations were negatively associated with this phenotype. BP_biochemical was negatively associated with DP_fresh_foods. Conclusion: we identified a negative association between a dietary pattern composed mainly of ultra-processed foods, fresh foods, and BP_adiposity. These associations need to be better explored, especially in adolescents, as both dietary patterns and phenotypes were defined using multivariate analysis.
Resumo Objetivos: investigar associação entre padrão alimentar (PA), atividade física (AF) e fenótipos corporais (FC) em adolescentes. Métodos: estudo transversal de base escolar com 1.022 adolescentes de dez a 19 anos. Padrão alimentar e fenótipo corporal foram definidos por meio da análise de componentes principais. O fenótipo corporal foi definido usando antropometria, composição corporal, bioquímica e maturação sexual, e padrão alimentar a partir de 19 grupos de alimentos de um questionário de frequência alimentar. A associação entre padrão alimentar e fenótipo corporal foi avaliada por modelo de regressão linear. Resultados: foram identificados cinco fenótipos corporais (FC1adiposidade, FC2puberdade, FC3bioquímico, FC4muscular, FC5lipídios_bioquímico) e cinco padrões alimentares (PA1alimentos_ultraprocessados, PA2alimentos_frescos, PA3pão_arroz_feijão, PA4preparações_culinárias, PA5bolos_arroz_feijão). Há maiores escores de FC_adiposidade para adolescentes com obesidade, mas o gasto energético foi semelhante para adolescentes com e sem diagnóstico de obesidade. Atividade física associou-se positivamente com IMC, FC_adiposidade e FC_puberdade. Observamos associação negativa entre PA_ultraprocessados e IMC, e positiva entre PA_alimentos_frescos. PA_alimentos_frescos associou-se positivamente com FC_adiposidade; PA_ultraprocessados e PA_preparações_culinárias se associaram negativamente a este fenótipo. FC_bioquímico associou-se negativamente com PA_alimentos_frescos. Conclusão: identificamos associação negativa entre padrão alimentar composto principalmente por alimentos ultraprocessados e alimentos in natura e FC_adiposidade. Essas associações devem ser exploradas com o mesmo público em estudos futuros, principalmente em adolescentes, pois tanto o padrão alimentar quanto o fenótipo foram definidos por meio de análise multivariada.

ABSTRACT Introduction: the obesity is defined as the excessive accumulation of fat in different areas of the body, a condition that causes damage to health and is a critical risk factor for various comorbidities. Bariatric surgery is the therapeutic option with the best results. Methods: this is a retrospective descriptive study using data obtained from medical records from January 2018 to December 2020 on patients undergoing bariatric surgery. Statistical analysis used a significance level of p<0.05. Results: 178 medical records were included, 77.5% of which were women. The average age was 35.7 years (± 9.5), 63.8% of the patients were from Imperatriz, 98.3% reported a sedentary lifestyle, 38.7% regular alcohol consumption and 13% smoking. The prevalence of Class III obesity (BMI≥40 kg/m²) was 53.3%. The most common comorbidities were hepatic steatosis (64.6%), type 2 diabetes mellitus (DM2) (40.5%) and hypertension (38.7%). The main type of surgery performed was Roux-en-Y gastric bypass (RYGB) (89.3%). There was an association between median BMI and gender (p=0.008), with women showing higher values [43.4 (IQR 39.1 - 48.8)]. The mean BMI of patients who underwent RYGB was significantly higher compared to those who underwent vertical gastrectomy (VG) (p=0.009). There was a statistical association between DM2 (p=0.033) and depression (p=0.018) and the type of surgery performed. Conclusion: the clinical and epidemiological profile found showed a higher prevalence of females and individuals with Class III obesity. RYGB was the most commonly performed procedure, establishing an association with BMI and some of the patients' comorbidities.
RESUMO Introdução: a obesidade é definida pelo acúmulo excessivo de gordura em diferentes regiões corporais, condição que acarreta prejuízos à saúde e constitui fator de risco para diversas comorbidades. A cirurgia bariátrica é a opção terapêutica com melhores resultados para o seu tratamento. Métodos: estudo retrospectivo descritivo realizado com dados obtidos de prontuários médicos do período de janeiro/2018 a dezembro/2020, relacionados a pacientes submetidos à cirurgia bariátrica. As análises estatísticas realizadas adotaram nível de significância p<0,05. Resultados: foram incluídos 178 prontuários, sendo 77,5% de mulheres. A média de idade foi de 35,7 anos (± 9,5), 63,8% dos pacientes eram procedentes de Imperatriz, 98,3% relataram sedentarismo, 38,7% consumo regular de álcool e 13% tabagismo. A prevalência de obesidade grau III (IMC≥40 kg/m²) foi de 53,3%. As comorbidades mais relacionadas foram esteatose hepática (64,6%), diabetes mellitus tipo 2 (DM2) (40,5%) e hipertensão arterial (38,7%). O principal tipo de cirurgia realizada foi o by-pass gástrico em Y de Roux (BGYR) (89,3%). Observou-se associação entre a mediana de IMC e o sexo (p=0,008), com as mulheres apresentando maiores valores [43,4 (IIQ 39,1 - 48,8)]. A média de IMC dos pacientes submetidos ao BGYR foi significativamente maior comparado aos que realizaram gastrectomia vertical (GV) (p=0,009). Houve associação estatística entre o DM2 (p=0,033) e a depressão (p=0,018) com o tipo de cirurgia realizada. Conclusão: o perfil clínico-epidemiológico encontrado evidenciou maior prevalência do sexo feminino e de indivíduos com obesidade grau III. O BGYR foi o procedimento mais realizado, estabelecendo associação com IMC e algumas comorbidades apresentadas pelos pacientes.
