Association between bone mineral density and content and physical growth parameters among children and adolescents diagnosed with HIV: a cross-sectional study

ABSTRACT BACKGROUND: During childhood and adolescence, there are significant increases in bone mineral content (BMC) and bone mineral density (BMD). OBJECTIVE: To investigate physical growth parameters associated with BMD and BMC among children and adolescents diagnosed with human immunodeficiency virus (HIV). DESIGN AND SETTING: Cross-sectional study conducted in Florianópolis, Brazil, among 63 children and adolescents (aged 8-15 years) diagnosed with HIV. METHOD: BMD, BMC and fat percentage z score were evaluated using dual X-ray absorptiometry. Age/height z score and body mass index (BMI)/age z score were obtained in accordance with international recommendations, and bone age was obtained through hand-wrist radiography. Sex, family income, information on HIV infection (T CD4+ lymphocyte count, viral load and type of antiretroviral therapy, moderate-vigorous physical activity and sedentary behavior) were used as adjustment variables in the analyses. Simple and multiple linear regression analyses were performed, with a significance level of P ≤ 0.05. RESULTS: Subtotal BMD (without the head region) was directly associated with bone age, BMI/age z score and fat percentage z score, even after adjusting for covariates. Subtotal BMC/height was directly associated with bone age, height/age z score, BMI/age z score and fat percentage z score, even after adjusting for covariates. CONCLUSION: Subtotal BMD and subtotal BMC/height were directly associated with physical growth indicators among children and adolescents diagnosed with HIV.

Physical activity and perceived environment among adults from a city in Southern Brazilian / Atividade física e percepção do ambiente em adultos de uma cidade do Sul do Brasil

Abstract The article aimed to verify the association between physical activity (PA) and perceived environment among adults from a city in southern Brazil. This is a population-based cross-sectional study with 820 adults living in the city of Criciúma-SC. Perceived environment was assessed using the Neighborhood Environmental Walkability scale and PA in the leisure and transportation domains using the long version of the International PA Questionnaire. It was observed that the neighborhood with public spaces for the practice of physical exercises and dog walking was associated with higher prevalence of compliance with moderate-to-vigorous physical activity (MVPA) guidelines. The fact of having an invitation from friends and/or relatives for PA, sporting events and the habit of dog walking were associated with leisure-time walking. Access to places for the purchase of fresh fruits/ vegetables, light/diet foods, to have sidewalks in most streets, to have pedestrian crossings and sporting events in the neighborhood were associated with higher prevalence of active transportation. Conversely, places for snacks or fast food in the neighborhood were associated with lower prevalence of active transportation. The perception of environmental variables was associated with MVPA, walking and active transportation.

Resumo O objetivo foi verificar a associação entre a prática de atividade física (AF) e a percepção do ambiente em adultos de uma cidade do Sul do Brasil. Estudo transversal de base populacional com 820 adultos, residentes na cidade de Criciúma-SC. A percepção do ambiente foi avaliada pela escala Neighborhood Environmental Walkability, e a AF no domínio do lazer e transporte ativo pela versão longa do Questionário Internacional de AF. Observou-se que o bairro com lugar público para a prática de exercícios físicos e o fato de passear com o cachorro estiveram associados a maiores prevalências de atendimento às recomendações de AF moderada à vigorosa (AFMV). O fato de ter convite de amigos e/ou parentes para AF, a realização de eventos esportivos e o hábito de passear com o cachorro estiveram associados à caminhada no lazer. O acesso a locais para aquisição de frutas/legumes frescos, alimentos light/diet, ter calçadas na maioria das ruas, ter faixas de segurança e ter eventos esportivos no bairro estiveram associados a maiores prevalências de deslocamento ativo. De forma contrária, lugares para lanches ou fast-food no bairro se associaram a menor prevalência de deslocamento ativo. A percepção de variáveis do ambiente esteve associada à AFMV, à prática de caminhada e ao transporte ativo.

Excesso de adiposidade corporal periférica, central e geral em adolescentes de uma cidade do sul do Brasil / Excess of peripheral, central and general body adiposity in adolescents in a city in southern Brazil

Objetivo: estimar a prevalência e analisar os fatores sociodemográficos e de estilo de vida associados ao excesso de adiposidade periférica, central e geral em adolescentes. Método: estudo transversal, realizado na cidade de São José/Santa Catarina, Brasil, com 1.132 adolescentes (14-19 anos). As variáveis dependentes foram adiposidade periférica (dobra cutânea [DC] do tríceps), central (DC subescapular) e geral (presença de adiposidade periférica e central), classificadas pelo percentil 90 do Centers for Disease Control and Prevention. As variáveis independentes foram nível econômico, atividade física (AF) e hábitos alimentares, obtidos por meio de questionários. A maturação sexual foi avaliada segundo critérios de Tanner. Resultados: o excesso de adiposidade periférica, central e geral, foi de 11,1%, 10,3% e 7,1%, respectivamente, para adolescentes do sexo masculino e, 13,1%,14,7% e 9,8%, respectivamente, para adolescentes do sexo feminino. Os adolescentes do sexo masculino com baixos níveis de AF apresentaram maiores chances de excesso de adiposidade periférica (OR:2,32; IC95%: 1,09-5,37). As adolescentes do sexo feminino, no estágio maturacional pós-púbere apresentaram maiores chances de excesso de adiposidade central (OR:3,80; IC95%:2,25-6,41) e geral (OR:3,31; IC95%:1,79-6,10), e aquelas que estudavam no período noturno apresentaram menores chances de ter excesso de adiposidade central (OR:0,35; IC95%:0,18-0,71) e geral (OR:0,43; IC95%:0,19-0,95). Conclusão: o excesso de adiposidade se fez presente, sendo que o baixo nível de AF para os adolescentes do sexo masculino, o estágio maturacional póspúbere e o turno de estudo diurno foram fatores associados ao excesso de adiposidade para as adolescentes do sexo feminino.

Objective: to estimate the prevalence and to analyze sociodemographic and lifestyle factors associated with excess peripheral, central and general adiposity in adolescents. Method: a cross-sectional study, conducted in the city of São José/Santa Catarina, Brazil, with 1,132 adolescents (14-19 years old). The dependent variables were peripheral adiposity (tríceps skinfold), central (subscapular skinfold) and general (presence of peripheral and central adiposity), classified from the 90th percentile of the Centers for Disease Control and Prevention curve. The independent variables were economic level, physical activity (PA) and eating habits, obtained through questionnaires. The sexual maturation was evaluated according to Tanner criteria. Results: the excess of central and general peripheral adiposity was 11.1%, 10.3% and 7.1%, respectively, for male adolescents and 13.1%, 14.7% and 9.8%, respectively, for adolescent females. Males with low PA l evels presented higher odds of excess peripheral adiposity (OR: 2.32; 95% CI: 1.09-5.37). The female adolescents in the post-pubertal maturational stage presented higher odds of excess central adiposity (OR: 3.80; 95% CI: 2.25-6.41) and general adiposity (OR: 3.31; 95% CI: 1.79-6.10), and those who studied at night had a lower chance of having excess central adiposity (OR: 0.35, 95% CI: 0.18-0.71) and general adiposity (OR: 0.43; 95% CI: 0.19-0.95). Conclusion: the excess of adiposity was present and that the low level of PA for the male adolescents, the post-pubertal maturational stage and the daytime shift were factors associated with excess adiposity for female adolescents.

What anthropometric indicators are associated with insulin resistance? Cross-sectional study on children and adolescents with diagnosed human immunodeficiency virus

ABSTRACT BACKGROUND: Studies that test associations between anthropometric indicators and insulin resistance (IR) need to provide better evidence in the context of the pediatric population (children and adolescents) with human immunodeficiency virus (HIV), as anthropometric indicators present a better explanation of the distribution of body fat. OBJECTIVE: To test the associations between anthropometric indicators and insulin resistance (IR) among children and adolescents diagnosed with HIV. DESIGN AND SETTING: Cross-sectional study on 65 children and adolescents (8-15 years) infected with HIV through vertical transmission conducted at the Joana de Gusmão Children's Hospital, Florianópolis, Brazil. METHODS: The anthropometric indicators measured were the abdominal (ASF), triceps (TSF), subscapular (SSF) and calf (CSF) skinfolds. The relaxed arm (RAC), waist (WC) and neck (NC) circumferences were also measured. Body mass index (BMI) was calculated from the relationship between body mass and height. IR was calculated through the Homeostasis Model Assessment for Insulin Resistance (HOMA-IR). Simple and multiple linear regression analyses were used. RESULTS: After adjustment for covariates (sex, bone age, CD4+ T lymphocytes, CD8+ T lymphocytes, viral load, and physical activity), associations between IR and models with SSF and CSF remained. Each of these explained 20% of IR variability. For females, in the adjusted analyses, direct associations between IR and models with ASF (R² = 0.26) and TSF (R² = 0.31) were observed. CONCLUSIONS: SSF and CSF in males and ASF and TSF in females were associated with IR in HIV-infected children and adolescents.

Aspects to consider in health professionals' promotion of physical activity / Aspectos a serem considerados na promoção de atividade física por profissionais de saúde

In Brazil, bodily practices and physical activity (BPPA) have come a long way, with the implementa-tion of policies, actions and programs that have substantially contributed to public health. However, recent setbacks, in which political instability, scarcity and cuts in public spending predominate, show that more progress and consolidation in the National Health System (SUS) are still needed. Thus, the objective of this article is to demonstrate the aspects that must be considered for promoting BPPA in primary health care, discussing its complexity and multifactorial nature, aimed at health profession-als, especially in physical education. In conclusion, essential aspects were highlighted, ranging from the struggle to defend and advance public policies that encourage the promotion and consolidation of the BPPA, to theories that help understand the dimensions of human behavior

No Brasil, as práticas corporais e atividade física (PCAF) obtiveram avanços com a implementação de políticas, ações e programas que contribuíram substancialmente com a saúde pública. Entretanto, recen-tes retrocessos, em que a instabilidade política, escassez e cortes de gastos públicos predominam, evidenciam o quando as PCAF ainda precisam avançar e serem consolidadas no Sistema Único de Saúde. Assim, o objetivo desse ensaio é demonstrar os aspectos que devem ser considerados para a promoção das PCAF na Atenção Primária à Saúde, trazendo reflexões quanto a sua complexidade e multifatoriedade. Essa reflexão é direcionada aos profissionais de saúde, sobretudo aos profissionais de Educação Física. Em conclusão, foram ressaltados aspectos essenciais, que vão desde a luta pela defesa e avanço de políticas públicas que incentivem o fomento e consolidação das PCAF até a apropriação de teorias que ajudem a compreender a dimensão do comportamento humano

Efeito de um Programa de Exercício Físico na Pressão Arterial Aguda e Crônica em Sobreviventes de Câncer de Mama / Effect of a Physical Exercise Program on Acute and Chronic Blood Pressure in Breast Cancer Survivors / Efecto de un Programa de Ejercicio Físico sobre la Presión Arterial Aguda y Crónica en Supervivientes de Cáncer de Mama

Introdução: Poucos estudos exploraram o desfecho de componentes hemodinâmicos em sobreviventes de câncer em um programa de exercícios físicos. Objetivo: Verificar alterações agudas e crônicas na pressão arterial sistólica (PAS) e diastólica (PAD) durante um programa de exercícios em sobreviventes de câncer de mama. Método: Em um hospital de referência, 24 mulheres sobreviventes participaram de um programa de exercícios físicos. A PA foi monitorada com monitor digital de pulso, antes e após a realização das sessões. Para comparação pré e pós-exercício em cada sessão, foi empregado o teste t para amostras pareadas. Para análises dos efeitos crônicos, utilizou-se a análise de variância (Anova), com medidas repetidas para identificar possíveis diferenças nas variáveis PAS e PAD pré-exercício ao longo das 15 sessões de treinamento. Considerou-se o nível de significância de 5%. Resultados: Observou-se que, com exceção da quarta e sexta sessões, os níveis de PAS diminuíram em todas as sessões após o exercício (p≤0,05). Para a PAD, somente houve diminuição significativa após o exercício nas três primeiras sessões. Nos efeitos crônicos, ocorreu redução média nos valores de PAS em repouso ao longo das sessões, com efeito hipotensor acima de 70% a partir da sétima sessão (p≤0,05). Na PAD, diferenças nos valores em repouso se acentuaram a partir da décima sessão; ao comparar com os valores de PAD em repouso, verificou-se efeito hipotensor acima de 94%. Conclusão: Sobreviventes que aderiram ao programa de exercício físico apresentaram redução aguda e crônica da PAS e da PAD

Introduction: Few studies have explored the outcome of hemodynamic components in cancer survivors in physical exercise programs. Objective: The main objective of this study was to verify acute and chronic changes in systolic (SBP) and diastolic (DBP) blood pressure during an exercise program for breast cancer survivors. Method: In a referral hospital, 24 surviving women participated in a physical exercise program. The BP was monitored with a digital wrist monitor, before and after the sessions. For pre and post-exercise comparison in each session, the t test for paired samples was used. For analysis of chronic effects, analysis of variance (ANOVA) was used, with repeated measures to identify possible differences in pre-exercise variables SBP and DBP throughout the 15 sessions. The level of significance was 5%. Results: It was noticed that, with the exception of the fourth and sixth sessions, the SBP levels decreased in all sessions after exercise (p≤0.05). For DBP, there was only a significant decrease after exercise in the first three sessions. For chronic effects, there was an average reduction in the values of SBP at rest throughout the sessions, with a hypotensive effect above 70% from the seventh session (p≤0.05). In DBP, differences in SBP values at rest were accentuated after the tenth session; when comparing with the values of DBP at rest, a hypotensive effect above 94% was observed. Conclusion: Survivors who adhered to the physical exercise program showed acute and chronic reduction in SBP and DBP

Introducción: Pocos estudios han explorado el resultado de los componentes hemodinámicos en sobrevivientes de cáncer en un programa de ejercicio.

Para DBP, solo hubo una disminución significativa después del ejercicio en las primeras tres sesiones. En los efectos crónicos, hubo una reducción media de los valores de PAS en reposo a lo largo de las sesiones, con un efecto hipotensivo superior al 70% a partir de la séptima sesión (p≤0,05). En PAD, las diferencias en los valores en reposo aumentaron a partir de la décima sesión; al comparar con los valores de PAD en reposo se observó un efecto hipotensor superior al 94%. Conclusión: Los supervivientes que se adhirieron al programa de ejercicio físico mostraron una reducción aguda y crónica de la PAS y la PAD

Physical activity to prevent stroke mortality in Brazil (1990-2019)

Abstract INTRODUCTION: This study aimed to estimate the burden of stroke mortality due to low levels of physical activity (PA) in Brazil from 1990 to 2019. METHODS: Data from the 2019 Global Burden of Disease (GBD) study for Brazil and Brazilian states were used. We used the number of deaths, age-standardized mortality rates, summary exposure value, and fraction of population risk attributable to low levels of PA. To standardize all estimates, data from the population aged 25 years or older were considered. RESULTS: The risk of exposure to low PA, SEV values, for the Brazilian male population was 11.8% (95%UI: 6.7; 19.9) and for the Brazilian female population was 13.2% (95%UI: 8.6; 19.2) in 2019. For males, it was estimated that there were, respectively, 2,025 (95%UI: 271; 4,839) and 3,595 (95%UI: 658; 7,302) deaths in 1990 and 2019 due to stroke attributable to low PA. For females, there were 2,518 (95%UI: 498; 5,006) and 4,735 (95%UI: 1,286; 8,495) deaths in 1990 and 2019 due to stroke attributable to low PA, respectively. From 1990 to 2019, reductions of 44.0% for males (95%UI: −0.54; -0.05) and 52.0% for females (95%UI: −0.60; -0.30) in age-standardized mortality rates due to stroke attributed to low PA were observed. Approximately 6.1% (for males) and 7.3% (for females) of deaths in 2019 due to stroke could be avoided if the Brazilian population were physically active. CONCLUSIONS: These findings support the promotion of PA in all Brazilian states for preventing early mortality due to stroke.

Associação entre insatisfação com a imagem corporal e indicadores antropométricos de obesidade em escolares do sul do brasil / Association between body image dissatisfaction and anthropometric indicators of obesity in students from southern brazil

O objetivo do presente estudo foi investigar a associação entre a insatisfação com a imagem corporal, por excesso de peso e pela magreza, e diferentes indicadores antropométricos de obesidade em adolescentes do sul do Brasil. Caracterizou-se com um estudo transversal, realizado na cidade de Criciúma ­ SC, com 575 adolescentes de 11 a 17 anos, de ambos os sexos. A imagem corporal foi avaliada por meio de escala de silhuetas. Os indicadores antropométricos de obesidade Índice de Massa Corporal, Relação Cintura-Estatura, Perímetro da Cintura e Índice de Conicidade foram avaliados conforme protocolo da Sociedade internacional para o Avanço da Cineantropometria. Adolescentes do sexo masculino, de 11 a 13 anos insatisfeitos pela magreza, apresentaram menores chances de ter Relação Cintura-Estatura elevada (RC: 0,1; IC95%: 0,04 - 0,51) e maiores chances de ter Índice de Conicidade elevado (RC: 4,4; IC95%:1,28-15,20) quando comparados com adolescentes satisfeitos com a imagem corporal. Adolescentes do sexo feminino, de 11 a 13 anos insatisfeitas pela magreza, apresentaram menores chances de ter Índice de Massa Corporal (RC: 0,1; IC95%: 0,02 - 0,58) e Índice de Conicidade (RC: 0,2; IC95%: 0,05 - 0,94) elevados e maiores chances de ter Relação Cintura-Estatura elevada (RC: 23,6; IC95%: 3,35-166,85) quando comparadas às adolescentes satisfeitas com a imagem corporal. Concluiu-se que existe associação entre a imagem corporal e indicadores antropométricos de obesidade para adolescentes de 11 a 13 anos, principalmente nos insatisfeitos pela magreza. No sexo masculino, distintos indicadores antropométricos de obesidade abdominal trazem interpretações distintas na associação com a imagem corporal. No sexo feminino, indica distorção da própria imagem corporal, que pode levar as adolescentes a adotarem comportamentos alimentares inadequados, levando à riscos à sua saúde. (AU)

The aim of the present study was to investigate the association between body image dissatisfaction due to overweight and thinness and different anthropometric indicators of obesity in adolescents from southern Brazil. Characterized as a Cross - sectional study conducted in the city of Criciúma - SC, with 575 adolescents aged 11-17 years of both sexes. Body image was assessed by a silhouette scale. Anthropometric indicators of obesity body mass index, waist-to-height ratio, waist circumference and conicity index were evaluated according to the International Society for the Advancement of Kinantropometry protocol. Male adolescents aged 11-13 years dissatisfied due to thinness, were less likely of having high waist-to-height ratio (OR: 0.1; 95% CI: 0.04 - 0.51) and more likely of having elevated conicity index (OR: 4.4; 95% CI: 1.28-15.20) when compared to adolescents satisfied with their body image. Female adolescents aged 11-13 years dissatisfied due to thinness were less likely of having high body mass index (OR: 0.1; 95% CI: 0.02 - 0.58) and conicity index (OR: 0.2; 95% CI: 0.05 - 0.94) and more likely of having high waist-to-height ratio (OR: 23.6; 95% CI: 3.35-166.85) when compared to adolescents satisfied with their body image. Concluded that there is an association between body image and anthropometric indicators of obesity for adolescents aged 11-13 years, especially those dissatisfied due to thinness. In males, different anthropometric indicators of abdominal obesity bring different interpretations in association with body image. In females, it indicates distortion of their own body image, which can lead adolescents to adopt inappropriate eating behaviors, leading to health risks. (AU)

Association between handgrip strength and bone mass parameters in HIV-infected children and adolescents. A cross-sectional study

ABSTRACT BACKGROUND: Low bone mineral content (BMC) and bone mineral density (BMD) have been identified in human immunodeficiency virus (HIV)-infected children and adolescents. The direct adverse effects of HIV infection and combined antiretroviral therapy (ART) negatively contribute to bone metabolism. A direct relationship between muscle strength levels and BMD in HIV-infected adults and older adults has been described. However, it is unknown whether handgrip strength (HGS) is associated with bone mass in pediatric populations diagnosed with HIV. OBJECTIVE: To ascertain whether HGS levels are associated with BMC and BMD in HIV-infected children and adolescents. DESIGN AND SETTING: Cross-sectional study conducted in Florianãpolis, Brazil, in 2016. METHODS: The subjects were 65 children and adolescents (8-15 years) diagnosed with vertically-transmitted HIV. Subtotal and lumbar-spine BMC and BMD were obtained via dual-emission X-ray absorptiometry (DXA). HGS was measured using manual dynamometers. The covariates of sex, ART, CD4+ T lymphocytes and viral load were obtained through questionnaires and medical records. Sexual maturation was self-reported and physical activity was measured using accelerometers. Simple and multiple linear regression were used, with P < 0.05. RESULTS: HGS was directly associated with subtotal BMD (β = 0.002; R² = 0.670; P < 0.001), subtotal BMC (β = 0.090; R² = 0.734; P = 0.005) and lumbar-spine BMC (β = 1.004; R² = 0.656; P = 0.010) in the adjusted analyses. However, no significant association was found between HGS and lumbar-spine BMD (β = 0.001; R² = 0.464; P = 0.299). CONCLUSION: HGS was directly associated with BMD and BMC in HIV-infected children and adolescents.

Agrupamentos de fatores de risco cardiometabólicos e sua associação com aterosclerose e inflamação crônica em adultos e idosos em florianópolis, Sul do Brasil / Clusters of cardiometabolic risk factors and their association with atherosclerosis and chronic inflammation among adults and elderly in florianópolis, Southern Brazil

Resumo Fundamento O aumento significativo de doenças cardiovasculares em países em desenvolvimento alerta sobre seu impacto em populações carentes. Objetivo Identificar a relação de agrupamentos de componentes da síndrome metabólica (SM) com aterosclerose e inflamação crônica em adultos e idosos. Métodos Análise transversal usando dados de dois estudos populacionais de tipo coorte realizados em Florianópolis, sul do Brasil (EpiFloripa Adult Cohort Study, n = 862, 39,9±11,5 anos; EpiFloripa Aging Cohort Study, n = 1197, 69,7±7,1 anos). Pressão arterial (PA), circunferência da cintura (CC), e níveis plasmáticos de lipídio e glicose foram analisados como fatores individuais ou como agrupamentos de componentes da SM (como número de componentes presentes em um indivíduo ou como combinações). Os desfechos incluíram espessura intima-media carotídea (EIMC), placas ateroscleróticas, e níveis de proteína C reativa (CRP). Regressão linear múltipla e regressão logística, ajustadas quanto aos fatores de confusão, foram usadas para análise. O nível de significância adotado foi de 5%. Resultados Indivíduos com PA e CC elevadas, dislipidemia e hiperglicemia (61,5%) apresentaram maiores valores de EIMC e PCR que aqueles que não apresentaram componentes de SM. CC elevada foi um determinante comum de inflamação sistêmica, ao passo que a coexistência de PA elevada e CC elevada (agrupamentos de dois ou três fatores) associou-se com maior EIMC (β entre +3,2 e +6,1 x 10-2 mm; p < 0,05) e PCR (EXPβ entre 2,18 e 2,77; p < 0,05). Conclusão A coexistência de PA e CC elevadas associou-se com maiores valores de EIMC e níveis de PCR. A obesidade central, isolada ou em combinação com outros fatores de risco, teve efeito sobre a inflamação sistêmica.

Abstract Background The significant increase in cardiovascular diseases in developing countries alerts about their impact on underprivileged populations. Objective To identify the relationship of clusters of metabolic syndrome (MS) components with atherosclerosis and chronic inflammation among adults and elderly. Methods Cross-sectional analysis using data from two population-based cohort studies in Florianópolis, Southern Brazil (EpiFloripa Adult Cohort Study, n = 862, 39.9±11.5 years; EpiFloripa Aging Cohort Study, n = 1197, 69.7±7.1 years). Blood pressure (BP), waist circumference (WC), and lipid and glucose levels were analyzed as individual factors or as clusters (either as the number of components present in an individual or as combinations of components). Outcomes included carotid intima-media thickness (IMT), atherosclerotic plaques, and C-reactive protein (CRP) levels. Multiple linear and logistic regression analyses adjusted for confounding factors were used. The statistical significance adopted was 5%. Results Individuals with high BP, elevated WC, dyslipidemia and hyperglycemia (6.1% of the sample) showed higher IMT and CRP than those negatives for all MetS components. Elevated WC was a common determinant of systemic inflammation, while the coexistence of high BP and elevated WC (clusters of two or three factors) was associated with higher IMT (β between +3.2 and +6.1 x 10-2 mm; p value < 0.05) and CRP (EXPβ between 2.18 and 2.77; p value < 0.05). Conclusion The coexistence of high BP and elevated WC was associated with increased IMT and CRP levels, but central obesity affected systemic inflammation either alone or in combination with other risk factors.

Body composition among university female athletes of team sports / Composición corporal entre atletas universitarias de deportes colectivos / Composição corporal entre atletas universitárias de esportes coletivos

ABSTRACT Introduction: The assessment of body composition in female athletes of different sports is important for health monitoring. Objective: To compare body composition in university athletes of different team sports (indoor soccer, flag football and volleyball). Methods: A cross-sectional study carried out with 45 female athletes, aged 18 to 35 years (22.8 ± 3.55). The dependent variables were body fat mass (FM) and fat-free mass (FFM) measured by air displacement plethysmography. Bone mineral content, adjusted for height (BMC/height) and bone mineral density (BMD), were measured by dual energy X-ray absorptiometry. The independent variable was sport [flag football (n = 12); indoor soccer (n = 20); volleyball (n = 13)] and the covariates were age (complete years), training volume (minutes per week) and length of time playing the sport (complete years). Analysis of covariance was used. Results: Adjusting the model for covariates, volleyball athletes (19.27 kg ± 2.20) presented higher FM values compared to the flag football (16.00 kg ± 1.70) and indoor soccer players (12.20 kg ± 1.30). There was no significant difference in FFM, BMC/height and total BMD between sports, even after adjusting for covariates. Conclusion: Volleyball athletes presented higher FM compared to flag football and indoor soccer athletes. There were no differences in FFM, BMC/height and BMD among the players of the different team sports. This study can help coaches and other sports professionals to prevent injuries to athletes in sports such as higher FM (volleyball), or to prevent diseases such as menstrual irregularities, which are common in athletes who may have low levels of body fat (indoor soccer players), this being one of the risk factors for the female athlete triad (eating disorders, menstrual irregularities and low BMD). Level of evidence III; Retrospective comparative study .

RESUMEN Introducción: La evaluación de la composición corporal en atletas del sexo femenino de diferentes modalidades deportivas es importante para la monitorización de la salud. Objetivos: Comparar la composición corporal de atletas universitarias, de diferentes modalidades colectivas (fútbol de salón, flag football y vóleibol). Métodos: Estudio transversal realizado con 45 atletas del sexo femenino, con edades entre 18 y 35 años (22,8 ± 3,55). Las variables dependientes fueron la masa grasa (MG) y masa magra (MM) medida por pletismografía por desplazamiento de aire. El contenido mineral óseo ajustado para estatura (CMO/estatura) y densidad mineral ósea (DMO) fueron medidos por absorciometría por doble emisión de rayos X. Las variables independientes fueron los deportes [flag football (n = 12); fútbol de salón (n = 20); vóleibol (n = 13)] y las covariables fueron edad (años completos), volumen de entrenamiento (minutos por semana) y tiempo de práctica (años completos). Fue utilizado el análisis de covariancia. Resultados: Al ajustar el modelo por las covariables, las atletas de vóleibol (19,27 kg ± 2,20) presentaron valores mayores de MG con relación a las de flag football (16,00 kg ± 1,70) y de fútbol de salón (12,20 kg ± 1,30). No hubo diferencia significativa en la MM, CMO/estatura y DMO total entre los deportes, incluso después del ajuste para las covariables. Conclusiones: Las atletas de vóleibol presentaron mayor MG en comparación con los atletas de flag football y fútbol de salón. No hubo diferencias en MM, CMO/estatura y DMO entre las jugadoras de diferentes modalidades colectivas. Este estudio puede ayudar a entrenadores y otros profesionales del deporte a prevenir lesiones en atletas con mayor MG (vóleibol) o prevenir enfermedades como irregularidades menstruales, comunes en atletas con bajos niveles de grasa corporal (fútbol de salón), que es uno de los factores de riesgo para el síndrome de la tríada de la atleta femenina (disturbios alimentarios, irregularidades menstruales y baja DMO). Nivel de evidencia III; Estudio retrospectivo comparativo .

As variáveis dependentes foram a massa gorda corporal (MG) e a massa magra (MM) medida por pletismografia por deslocamento de ar. O conteúdo mineral ósseo ajustado para estatura (CMO/estatura) e densidade mineral óssea (DMO) foram medidos por absorciometria por dupla emissão de raios X. As variáveis independentes foram os esportes [flag football (n = 12); futebol de salão (n = 20); voleibol (n = 13)] e as covariáveis foram idade (anos completos), volume de treinamento (minutos por semana) e tempo de prática (anos completos). A análise de covariância foi utilizada. Resultados: Ao ajustar o modelo pelas covariáveis, as atletas de voleibol (19,27 kg ± 2,20) apresentaram valores maiores de MG com relação às de flag football (16,00 kg ± 1,70) e de futebol de salão (12,20 kg ± 1,30). Não houve diferença significativa na MM, CMO/estatura e DMO total entre os esportes, mesmo depois do ajuste para as covariáveis. Conclusões: As atletas de voleibol apresentaram maior MG em comparação com as atletas de flag football e futebol de salão. Não houve diferenças em MM, CMO/estatura e DMO entre os jogadoras de diferentes modalidades coletivas. Este estudo pode ajudar treinadores e outros profissionais do esporte a prevenir lesões em atletas com maior MG (voleibol) ou prevenir doenças como irregularidades menstruais, comuns em atletas com baixos níveis de gordura corporal (futebol de salão), que é um dos fatores de risco para a síndrome da tríade da atleta feminina (distúrbios alimentares, irregularidades menstruais e baixa DMO). Nível de evidência III; Estudo retrospectivo comparativo .

Normative values of handgrip strength in adolescents according to chronological age and sexual maturation

Abstract Aim: Handgrip strength is considered an important health indicator. It is extremely important to establish normative values so that the handgrip strength is correctly interpreted in adolescents. The present study aims to establish normative values of handgrip strength (HGS) for adolescents, according to chronological age and sexual maturation. Methods: Data from three large projects carried out in Florianopolis and São José, Santa Catarina were used, corresponding to a sample of 2,637 adolescents aged 14 to 19 years old of both sexes (1,428 girls). The HGS of the right and left hands was measured by a manual dynamometer, and total HGS being defined by the sum of the left hand and the right-hand strength. Sexual maturation was determined by the development of pubic hair. The percentiles 3, 10, 15, 25, 50, 75, 85, 90, and 97 were calculated for the right, left, and total HGS. The percentile ranges < p15 (low), p15-p85 (normal) and > p85 (high) were used. ANOVA and Kruskal-Wallis tests were applied. Results: In boys, the mean total HGS ranged from 67.5 ± 16.5 to 86.9 ± 21.8 (p < 0.001) and 74.3 ± 17.5 to 82.2 ± 17.8 (p < 0.001) for age and sexual maturation, respectively, while in girls the mean HGS total ranged from 48.8 ± 11.3 to 56.4 ± 16.0 (p = 0.127) and 47.8 ± 10.6 to 54.3 ± 12.3 (p < 0.001). Conclusion: Reference values established by the percentile score, can be used to identify adolescents with better athletic condition and can be useful for prescribing exercises.

Prevalence of Brazilian children and adolescents who met health criteria for aerobic fitness: systematic review update for Report Card Brazil Project / Prevalência de crianças e adolescentes brasileiros que atenderam aos critérios de saúde para aptidão aeróbia: atualização de revisão sistemática para o Projeto Report Card Brasil

abstract The aim of the study was to update Brazilian evidence on the prevalence of children and adolescents who met health criteria for aerobic fitness. This systematic review is part of the Report Card Brazil Project and the search was restricted to studies published during the period from January 2018 to December 2019 in nine electronic databases. Studies with different designs, which allowed extracting information about the prevalence of children and adolescents who met health criteria for aerobic fitness (age up to 19 years or average age up to 19 years) were included. Studies published from 2020 were not included due to the possible effect of the pandemic on this indicator and because there is no certainty as to when the pandemic will end. Of the 694 studies initially identified, 13 studies with information of 14,673 children and adolescents were included after reading titles, abstracts, full texts and references. The prevalence of children and adolescents who met health criteria for aerobic fitness was 26.9% (29.7% for girls; 44.6% for boys). In this search, eight different cutoff points were used to determine adequate aerobic fitness levels and five tests were used to determine aerobic fitness. Analyzing data from the present review with the previous systematic review of this project, one third of children and adolescents in Brazil meet health criteria for aerobic fitness.

resumo O objetivo do estudo foi realizar uma atualização das evidências brasileiras sobre a prevalência de crianças e adolescentes que atenderam aos critérios de saúde para aptidão aeróbia. Essa revisão sistemática integra o Projeto Report Card Brasil e a busca foi restrita aos estudos publicados durante o período de Janeiro de 2018 a Dezembro de 2019 em nove bases de dados eletrônicas. Estudos com diferentes delineamentos, os quais permitiram extrair informações acerca da prevalência de crianças e adolescentes que atenderam aos critérios de saúde para a aptidão aeróbia (idade até 19 anos ou com média de idade até 19 anos) foram incluídos. Estudos publicados a partir de 2020 não foram incluídos por conta do possível efeito da pandemia nesse indicador e por não haver uma certeza de quando finalizará a pandemia. Do total de 694 estudos inicialmente identificados, 13 estudos com informações de 14.673 crianças e adolescentes foram incluídos após a leitura de títulos, resumo, textos completos e referências. A prevalência de crianças e adolescentes que atenderam aos critérios de saúde para aptidão aeróbia foi de 26.9% (29,7% para as meninas; 44,6% para os meninos). Nessa busca, oito pontos de corte distintos para determinar níveis adequados de aptidão aeróbia foram utilizados, bem como cinco testes foram empregados para se determinar a aptidão aeróbia. Analisando-se os dados da presente revisão com a revisão sistemática anterior desse projeto, um terço das crianças e adolescentes do Brasil atendem aos critérios de saúde para aptidão aeróbia.

Report Card Brazil: systematic review of muscle strength assessment in children and adolescents in Brazil / Report Card Brasil: revisão sistemática sobre avaliação da força muscular em crianças e adolescentes no Brasil

ABSTRACT The present study aimed to identify and summarize evidence regarding muscle strength (MS) levels in school children and adolescents (≤ 19 years) in Brazil in order to update previously published evidence from the Report Card Brazil project. The systematic search for information was conducted in seven databases, restricted to studies published during the period from January 2018 to December 2019. Thirteen studies were included, which gathered information from 10,135 children and adolescents from seven Brazilian states. Different tests/protocols for assessing MS were identified, however, handgrip strength was the test most adopted in studies (53.8%). The prevalence of children and adolescents with MS levels considered healthy was 29.8%, considering the totality of information, and 27.6% for males and 31.8% for females. Considering full data reviewed by the Report Card Brazil project (data analyzed in this study in addition to those previously published), information regarding the assessment of MS levels in children and adolescents in Brazil came from studies conducted during the period from 2010 to 2019, which included a sample of 15,208 children and adolescents (aged 7-19 years). According to this information, the prevalence of children and adolescents with MS levels considered healthy in this period was 57.8%, 61.1% for males and 58.8% for females.

RESUMO O estudo teve como objetivo identificar e sumarizar evidências referentes à avaliação dos níveis de força muscular (FM) em crianças e adolescentes escolares (≤ 19 anos) no Brasil, com o intuito de atualizar as evidências publicadas anteriormente pelo projeto Report Card Brazil. A busca sistemática das informações foi conduzida em sete bases de dados, restrita aos estudos publicados durante o período de Janeiro de 2018 a Dezembro de 2019. Treze estudos foram incluídos, o que reuniu informações de 10.135 crianças e adolescentes de sete estados brasileiros. Diferentes testes/protocolos para avaliar a FM foram identificados, contudo, a força de preensão manual foi o teste mais empregado pelos estudos (53,8%). A prevalência de crianças e adolescentes que apresentavam níveis de FM considerados saudáveis foi de 29,8% considerando a totalidade de informações, e 27,6% para os meninos e 31,8% para as meninas. Considerando a totalidade de dados revisados pelo projeto Report Card Brazil (informações analisadas neste estudo em adição aos anteriormente publicados), o corpo de informações referente a avaliação dos níveis de FM em crianças e adolescentes no Brasil foram advindas de pesquisas conduzidas durante o período de 2010 a 2019, o que reuniu amostra de 15.208 crianças e adolescentes (sete a 19 anos). De acordo com estas informações, a prevalência de crianças e adolescentes que apresentavam níveis de FM considerados saudáveis nesse período foi de 57,8%, sendo que no sexo masculino foi de 61,1% e no sexo feminino de 58,8%.

Social support from family and friends for physical activity in adolescence: analysis with structural equation modeling / Apoio social de familiares e amigos para atividade física em adolescentes: análise com modelagem de equações estruturais / Apoyo social de la familia y amigos para la actividad física de adolescentes: análisis con modelos de ecuaciones estructurales

Social support is an important predictor for the maintenance of physical activity in adolescence. Thus, the social-ecological approach values the impact of individuals or groups interaction with available resources in the social environment for adopting an active lifestyle. This study analyzes social support from family and friends for adolescents to practice physical activity. Guided by the Social-Ecological Theory, an observational cross-sectional structural equations modeling was applied to 2,710 Brazilians adolescents aged from 14 to 18 years. We identified that the greater the social support from friends (β = 0.30; RMSEA = 0.065; CFI = 0.953; TLI = 0.922; SRMR = 0.048) and family, the greater the adolescents physical activity (β = 0.27; RMSEA = 0.015; CFI = 0.997; TLI = 0.995; SRMR = 0.013). However, support from both sources indicated no adequate adjustment values in the same study model. Our findings suggest that adolescents who perceive social support from family members or friends practice more physical activity, confirming that social support is important for physical activity promotion.

O apoio social é um preditor importante da manutenção de atividade física na adolescência, sendo que a abordagem da ecologia social valoriza o impacto da interação entre indivíduos ou grupos com recursos disponíveis no ambiente social para adotar um estilo de vida saudável. Portanto, o estudo analisa as relações de apoio social de familiares e amigos para a prática de atividade física por adolescentes. Com base na Teoria de Ecologia Social, os autores aplicam a modelagem de equações estruturais com uma perspectiva observacional e desenho transversal, com 2.710 adolescentes brasileiros entre 14 e 18 anos de idade. Foi possível mostrar que níveis maiores de apoio social dos amigos (β = 0,30; RMSEA = 0,065; CFI = 0,953; TLI = 0,922; SRMR = 0,048) e dos familiares estão associados com maior atividade física nos adolescentes (β = 0,27; RMSEA = 0,015; CFI = 0,997; TLI = 0,995; SRMR = 0,013). Entretanto, o apoio de ambas as fontes no mesmo modelo analítico não indicou bons valores de ajuste. Os achados sugerem que os adolescentes que recebem apoio social de familiares ou amigos apresentam melhores níveis de atividade física, confirmando o apoio social como importante fator de promoção da prática de atividade física.

El apoyo social es un importante predictor para el mantenimiento de la actividad física en la adolescencia, por ello, el enfoque socioecológico valora el impacto de la interacción entre individuos, o grupos con recursos disponibles en el entorno social, con el fin de adoptar un estilo de vida activo. Por lo tanto, este estudio analiza el apoyo social de las relaciones de familia y amigos para la práctica de actividad física de adolescentes. Utilizando la Teoría Ecológica Social, aplicamos modelos de ecuaciones, desde una perspectiva observacional con diseño transversal, en la que participaron 2.710 brasileños adolescentes, de 14 a 18 años de edad. Fue posible identificar que cuanto mayor era el apoyo social de los amigos (β = 0,30; RMSEA = 0,065; CFI = 0,953; TLI = 0,922; SRMR = 0,048), al igual que el apoyo social de la familia, mayor era la actividad física de los adolescentes (β = 0,27; RMSEA = 0,015; CFI = 0,997; TLI = 0,995; SRMR = 0,013). Sin embargo, el respaldo de ambas fuentes en el mismo modelo de análisis no indicó valores de ajuste adecuados. Los resultados sugieren que los adolescentes que percibieron un apoyo social de los miembros de la familia o amigos tienen niveles mejores de actividad física. Este resultado confirma que el apoyo social es un importante promotor de la práctica de actividad física.

Moderator role of vitamin D concentrations on the association between metabolic syndrome and C-reactive protein among adults

ABSTRACT Objective To evaluate the association between MetS, its components and insulin resistance (IR) with 25(OH)D and hsCRP. The moderator role of 25(OH)D in the association of MetS, its diagnostic components and IR with hsCRP were also explored. Materials and methods A cross-sectional study (2014/2015) with a population-based cohort in Southern Brazil (n = 605). Metabolic syndrome (MetS) diagnosis was defined based on the Joint Interim Statement, while the Homeostasis Model Assessment of insulin resistance (IR) (HOMA-IR) was used for determining IR. Serum concentrations of 25-hydroxy vitamin D [25(OH)D] (ng/mL) and high sensitivity C-reactive protein (hsCRP) (mg/L) were evaluated following standard protocols. 25(OH)D was categorized as sufficiency (>30 ng/mL), insufficiency (20-30 ng/mL) or deficiency (<20 ng/mL) to test its moderator role. Multiple linear regression was used to test the associations. The results were adjusted for possible confounders. Results and discussion Hypertriglyceridemia and IR were associated with lower 25(OH)D concentrations. However, except for systolic blood pressure, other MetS components and IR were associated with higher hsCRP. The association between elevated waist circumference (WC) and hsCRP was moderated by the 25(OH)D concentrations. The hsCRP median concentrations were more than two times higher among those with elevated WC and 25(OH)D insufficiency or deficiency. In this study, inadequate concentrations of 25(OH)D increased the adverse relationship between elevated WC and inflammation. 25(OH)D concentrations could be incorporated into the clinical protocols for monitoring individuals with abdominal obesity to identify those at a higher risk of complications.

Impact of physical activity on fatigue and quality of life of cancer patients / Impacto da atividade física na fadiga e qualidade de vida de pacientes com câncer / Impacto de la actividad física en la fatiga y calidad de vida de pacientes con cáncer

ABSTRACT Introduction: Physical exercise has been considered an important non-pharmacological treatment for reducing tiredness, pain, low self-esteem and increases in body mass in individuals diagnosed with cancer. Objective: To verify the relationship between fatigue, quality of life and levels of physical activity in cancer patients undergoing chemotherapy. Methods: Observational, cross-sectional study. The sample consisted of 85 adult patients undergoing cancer treatment at a university hospital. Physical activity was assessed by the IPAQ, and fatigue and quality of life by the PFS and EORTC QLQ-C30 questionnaires, respectively. Student's t and the Fisher's Exact tests were used to identify differences between active and physically inactive patients for the variables fatigue and quality. Additionally, covariance analysis (ANCOVA) was used, in which simple (outcome and exposure) and adjusted models (age, time of diagnosis and type of cancer) were tested. Results: The study included 85 cancer patients, with a mean of 51.78 years of age (±11.72). Most were female and not physically active. Patients classified as physically inactive had higher scores for "total fatigue" (p=0.01), "behavioral" (p=0.01), "affective" (p=0.02) and psychological/sensory fatigue (p=0.04), compared to the physically active patients (p=0.01). Patients classified as physically not very active presented poorer quality of life in the dimensions: "overall" quality of life (p=0.05) and "functional" (p=0.04), "appetite" (p=0.02), "insomnia" (p=0.0 2), "diarrhea" (p=0.04), "fatigue" (p=0.01), "pain" (p=0.01) and "nausea" (p=0.03), when compared to the physically active patients in both analyses; simple and adjusted. Conclusion: The practice of physical activity during treatment can be a determining factor for increasing quality of life and reducing fatigue in cancer patients, minimizing the adverse effects of chemotherapy. Level of evidence II; retrospective study.

RESUMO Introdução: O exercício físico tem sido considerado um importante tratamento não farmacológico para diminuir a sensação de cansaço, as dores, a baixa autoestima e o aumento da massa corporal em indivíduos com diagnóstico de câncer. Objetivo: Verificar a relação entre fadiga, qualidade de vida e níveis de atividade física em pacientes oncológicos submetidos à quimioterapia. Métodos: Estudo observacional, transversal. A amostra foi composta por 85 pacientes adultos em tratamento oncológico em hospital universitário. A atividade física foi avaliada pelo IPAQ, a fadiga e a qualidade de vida, pelos questionários PFS e EORTC QLQ-C30, respectivamente. Foram empregados os testes t de Student e Exato de Fisher para identificar diferenças entre os pacientes fisicamente ativos e pouco ativos para as variáveis de fadiga e qualidade de vida. Adicionalmente, foi empregada a análise de covariância (ANCOVA) em que foram testados modelos simples (desfecho e exposição) e ajustados (idade, tempo de diagnóstico e tipo de câncer). Resultados: Participaram do estudo 85 pacientes com câncer e média de 51,78 anos de idade (± 11,72). A maioria era do sexo feminino e pouco ativa fisicamente. Pacientes classificados como fisicamente pouco ativos apresentaram maiores escores de "fadiga total" (p = 0,01), "comportamental" (p = 0,01), "afetiva" (p = 0,02) e fadiga psicológica/sensorial (p = 0,04), em comparação com pacientes fisicamente ativos (p=0,01). Os pacientes classificados como fisicamente pouco ativos tinham pior qualidade de vida nas dimensões: qualidade de vida "geral" (p = 0,05) e "funcional" (p = 0,04), "apetite" (p = 0,02), "insônia" (p = 0,02), "diarreia" (p = 0,04), "fadiga" (p = 0,01), "dor" (p = 0,01) e "náuseas" (p = 0,03) quando comparados com os pacientes fisicamente ativos, em ambas as análises, simples e ajustada. Conclusão: A prática da atividade física durante o tratamento pode ser um fator determinante para aumentar a qualidade de vida e reduzir a fadiga em pacientes com câncer, minimizando os efeitos adversos da quimioterapia.

Associated factors with the isolated and simultaneous presence of overweight and abdominal obesity in adolescents / Fatores associados à presença isolada e simultânea de excesso de peso e obesidade abdominal em adolescentes

ABSTRACT Objective: To analyze the sociodemographic and lifestyle factors associated with excessive weight (EW), abdominal obesity (AO) and the simultaneous presence of EW and AO in adolescents from Southern Brazil. Methods: Cross-sectional study with 583 adolescents (11 to 17 years old) of Criciúma, Santa Catarina, Brazil. EW was assessed by body mass index (BMI) and AO by waist circumference (WC). The independent variables analyzed were gender, age, maternal schooling, balanced diet, physical activity, cigarette use, excessive alcohol use and screen time. Binary logistic regression was used to estimate Odds Ratios (OR) and 95% confidence intervals (95%CI). Results: Boys had 58% higher likelihood of having EW (OR 1.58; 95%CI 1.08-2.29; p<0.05). Younger age group (11 to 14 years) was directly associated with higher likelihood of EW (OR 6.07; 95%CI 4.05-9.11; p<0.05). Adolescents whose mothers had higher education had 75% more likelihood of having AO (OR 1.75; 95%CI 1.01-3.00; p<0.05). Higher likelihood for EW and AO (OR 1.84; 95%CI 1.01-3.34; p<0.05) was identified in younger adolescents (11 to 14 years). Conclusions: Boys and younger age (11 to 14 years) were associated with a higher likelihood of EW. Adolescents whose mothers studied nine years or more were more likely to have AO. The younger age group (11 to 14 years) was associated with greater chances for the simultaneous presence of EW and AO.

RESUMO Objetivo: Analisar os fatores sociodemográficos e do estilo de vida associados ao excesso de peso (EP), à obesidade abdominal (OA) e à presença simultânea de EP e OA em adolescentes do Sul do Brasil. Métodos: Estudo transversal de base escolar realizado com 583 adolescentes (11 a 17 anos) da cidade de Criciúma, Santa Catarina. O EP foi avaliado pelo índice de massa corpórea (IMC) e a OA, mediante perímetro da cintura (PC). As variáveis independentes analisadas foram sexo, idade, escolaridade materna, dieta balanceada, atividade física, uso de cigarro, uso de álcool em excesso e tempo de tela. Utilizou-se regressão logística binária para estimar as razões de chances (RC) e intervalos de confiança de 95% (IC95%). Resultados: Os meninos tiveram 58% de chances a mais de terem EP (RC 1,58; IC95% 1,08-2,29; p<0,05). Menor faixa etária (11 a 14 anos) foi diretamente associada a maiores chances de EP (RC 6,07; IC95% 4,05-9,11; p<0,05). Adolescentes cujas mães tinham maior escolaridade apresentaram 75% de chances a mais de terem OA (RC 1,75; IC95% 1,01-3,00; p<0,05). Maiores chances para a simultaneidade EP e OA (RC 1,84; IC95% 1,01-3,34; p<0,05) foram identificadas nos adolescentes de menor faixa etária (11 a 14 anos). Conclusões: Meninos e menor faixa etária (11 a 14 anos) estiveram associados a maiores chances para EP. Os adolescentes cujas mães estudaram nove anos ou mais apresentaram maiores chances de terem OA. Menor faixa etária (11 a 14 anos) esteve associada a maiores chances para a presença simultânea de EP e OA.

Analysis of factors related to the H Index of CNPq scientific productivity researchers in the field of Physical Education in Brazil

Abstract Aim: To verify the association between sociodemographic, academic background, professional performance, bibliographic production and training of human resources factors with the H Index of CNPq scientific productivity researchers in the field of Physical Education. Methods: This cross-sectional study included 94 researchers with scientific productivity grants (PQ) in the field of Physical Education in Brazil distributed into academic prestige level: PQ 1A-1D (n = 41) and PQ 2 (n = 53). For this, the H Index of these researchers was analyzed in the Scopus database. Related factors were sociodemographic, academic background, professional performance, bibliographic production, and training of human resources (student supervisor). Simple and multiple linear regression was used with a 5% significance level. Results: The H Index, number of citations, number of scientific articles in the last 10 years, number of books in the last 10 years, and the training of students at graduate levels of PQ 1A-1D was higher than that of PQ 2 (p <0.05). The H Index of PQ 1A-1D scholarship researchers was directly related to the number of scientific articles [H index = 8.48 + 0.11 * (Articles)]. The H index of PQ 2 scholarship researchers was directly related to the number of scientific articles and academic books and, inversely to the student supervision at master level [H index = 15.19 + 0.06 * (Articles) + 2.45 * (Books) - 0.34 * (Masters)]. Conclusion: H Index of researchers in the field of Physical Education in Brazil varied according to the academic recognition level.

Prevalence of body image dissatisfaction and association with teasing behaviors and body weight control in adolescents

Abstract Aims: The objective was to estimate the prevalence and the factors of behaviors of provocation and control of the weight associated with dissatisfaction with the body image among adolescents. Methods: Cross-sectional study with 580 adolescents (11 to 17 years old) from Criciúma, Brazil. The body image was evaluated by the silhouettes scale and the behaviors of provocation and weight control by questionnaires. A multinomial logistic regression was used (p ≤ 0.05). Results: Of the total number of adolescents, 48.6% were dissatisfied with being overweight (male 47.9%, female 49.3%) and 22.9% dissatisfied with thinness (male 23.8%, female 22.1%). Male adolescents who were dissatisfied with being overweight were more likely to be joked and laughed at because of their appearance and lower chances of being nicknames due to their size or body weight, while those who were unsatisfied with being thin were more likely to joke and laughter because of the appearance, compared to satisfied. Female adolescents who were dissatisfied with being overweight were more likely to be laughed at because they were uncoordinated and without food for 24 h, while those who were unsatisfied with being thin were less likely to be joking and laughing because of their appearance and higher chances to be the targets of laughter because they are uncoordinated, compared to those that are satisfied. Conclusion: The dissatisfaction with body image was associated with different behaviors of provocation and weight control according to sex.
