This study investigated the association among loneliness, number of friends, and participation in physical education classes, leisure-time physical activities, and active commuting. Data from 102,072 adolescents participating in the National School–based Health Survey aged 11–19 years were analyzed. Information about the study variables was self-reported through a questionnaire. Adolescents more active in physical education classes and leisure were less likely of having social isolation. Those more active in commuting were more likely of having social isolation. Interventions aimed at addressing social isolation in adolescence can prioritize school and leisure-time physical activities.
The aim of this study was to verify the association between school environment and accumulated physical activity in Brazilian adolescents. This is a study with secondary data from sample 1, from the third edition of the National School Health Survey, a study carried out with 102.072 children and adolescents enrolled in the ninth school grade. Questions about characteristics of the school environment and the offer of opportunities for physical activity practices were addressed, focusing on information regarding the structure for physical activity and about the regular practice of accumulated physical activities. Variables were organized from the structure of schools and opportunities for the practice of physical activities, while accumulated physical activity was used as the outcome variable. Data were analyzed from a binary logistic regression model, organized in crude and adjusted models, with a significance level of 5%. Data were analyzed from SPSS for Windows, version 22.0. Results indicate that, from the adjustment of variables, there was an association between the practice of accumulated physical activity and the existence of a sports court under conditions of use (OR=1.22, 95%CI=1.18-1.26), or presence of courtyard for use of physical education classes (OR=1.04, 95%CI=1.01-1.06). Association between the offer of varied physical activities, except for physical education classes, and the practice of accumulated physical activity (OR=1.05, 95%CI=1.02-1.08) was identified. Existence of a sports court/courtyard in schools and the offer of extracurricular physical activities are associated with the practice of accumulated physical activity in young Brazilian students.
The present study aimed to verify the contribution of different physical activity domains to “total physical activity” in Brazilian adolescents. This is a cross-sectional study using secondary data from the third edition of the National School Health Survey - PeNSE, 2015. The sample consisted of 100,497 adolescents of both sexes enrolled in the 9th grade of elementary schools. A linear regression model was used to verify how much each domain contributed to total physical activity, considering gender, type of municipality and region. The domain with the largest contribution to “total physical activity” regardless of sociodemographic and environmental variables was “extra-school physical activity” (R2 = 0.60), followed by “active commuting” (R2 = 0.34), and finally “Physical Education classes” (R2 = 0.23). The contribution of the different domains varied by gender, type of municipality and region, and it was concluded that “extra-school physical activity” make the greatest contribution to “total physical activity”, followed by “active commuting” and “Physical Education classes”. In addition, variation was observed in the contribution of domains by gender, type of municipality and region.
Flexibility is a health-related physical fitness component that has its importance related to the maintenance of functional independence and achievement of activities of the daily living. This systematic review aims to analyze the existing evidence in the literature regarding physical capacity flexibility in Brazilian children and adolescents. Searches were conducted in the Virtual Health Library, Scientific Electronic Library Online, Sportdiscus databases through the EBSCOhost and Pubmed platform. There were 89,553 articles, of which 69,197 were excluded for duplicity, 20,124 for the title, 160 for the abstract, 56 after a full analysis of the article, remaining 16 articles for the qualitative analysis. Of these, from the reading of references, 57 titles partially eligible for the review were identified, and after the application of the eligibility criteria, there were only 18 for the qualitative analysis. Of the 34 studies included for the qualitative analysis, 25 studies were excluded and nine were included in the review. All articles presented the cross-sectional design and used the sit-and-reach test to assess flexibility. It was evidenced that: a) flexibility has been treated as co-adjuvant in studies with children and adolescents; b) although females have absolute flexibility values greater than the opposite sex, males have higher frequency of subjects that meet the health classification criteria in this variable; c) there is greater prevalence of the use of FITNESSGRAM and PROESP-BR reference standards.
O presente estudo tem como objetivo avaliar a associação entre o comportamento do bullying, variáveis sociodemográficas e a atividade física acumulada em adolescentes escolarizados brasileiros. Trata-se de um estudo com dados secundários, utilizando dados da Amostra 2, da PeNSE 2015 (n = 10926). Para a análise de dados foi utilizada a regressão logística binária para estimar a chance de ocorrência do fenômeno do bullying na forma de Odds Ratio (OR) bruta e ajustada. Para a verificação dos fatores associados ao bullying em adolescentes brasileiros a amostra foi estratificada em “ativos” e “insuficientemente ativos”, de forma a entender o comportamento do bullying entre cada estrato. Observou-se que o sexo masculino apresentou duas vezes mais chances (OR = 1,99; IC95% 1,80 – 2,19) de apresentar este comportamento de bullying quando comparado com o sexo feminino. Verificou-se para o estrato “ativos”, associação entre perpetrar bullying e o sexo masculino (OR = 2,21; IC95% 1,82 - 2,67) e sofrer bullying enquanto auto percepção (OR = 2,45; IC95% 2,05 - 2,93). Para os “insuficientemente ativos”, percebeu-se associação no modelo ajustado entre “perpetrar bullying” e sexo masculino (OR = 1,88; IC95% 1,65 - 2,13). Notou-se que os adolescentes do sexo masculino, que sofriam bullying, tinham mais chance de praticar bullying. Os resultados sugerem ainda que, tanto no grupo “ativo” quanto no grupo de “insuficientemente ativo”, quem perpetra bullying tem mais chance de ter sofrido bullying, sugerindo que o comportamento do bullying é anterior à prática de atividade física.
Cardiorespiratory fitness is an important health status indicator. The purpose of this study was to verify the cardiorespiratory fitness according to age group and gender in children and adolescents from Sergipe, Brazil. It is a cross-sectional study with sample consisting of 195 adolescents of both genders with mean age of 11.75 ± 3.0 years. For the characterization of participants, a questionnaire with age and gender identification designed by researchers was used. Subsequently, participants were submitted to anthropometric evaluation in order to estimate the maturational stage by means of the peak height velocity (PHV). The 20-meter back-and-forth test was used to estimate cardiorespiratory fitness. Two-way ANOVA was applied with sample divided into two groups (“up to 13 years” and “above 13 years”). Polynomial contrast was used to identify the type of tendency for cardiorespiratory fitness, and simple contrast for multiple comparisons. All procedures were performed using SPSS version 22.0 software, considering 5% significance level. In the “over 13 years” group, there was a significant effect on the cardiorespiratory capacity behavior according to “gender” [F(1, 45) = 5.54, p = 0.02, r = 0.33] and “age” [F(4.45) = 3.37, p = 0.02, r = 0.48]. The simple contrast identified increased cardiorespiratory fitness behavior in relation to age groups of 15 and 16 year when compared to the age group of 14 years. It was concluded that gender and age positively influence cardiorespiratory fitness from the maturational reference age in the study group.
-The registration or insertion of older adults in Community Physical Activity Programs does not guarantee their stay over time. The purpose of this study was to analyze the length of stay of elderly in a Community Physical Activity Program and associated factors. This epidemiologic observational study of retrospective cohort performed in Aracaju City, Brazil, included a sample of 526 older adults (477 females) aged 66.4 ± 5.4 years. To characterize the profile and length of stay of individuals, descriptive statistics was used. To analyze the length of stay, the Kaplan-Meier non-parametric survival, estimator was used. To verify the association between variables in the observed time, the Cox regression model was applied. Inverse ratio equation (1/OR) was used to facilitate the understanding of significant values when necessary. In all analyses, 95% confidence interval and p≤0.05 were used. In the first three months, stay rate of 58.1% (95% CI = 54.6 -61.3) was observed, with a risk estimative = 41.82%. Females presented a 45% chance of stay (OR = 0.69; 95% CI = 0.51 -0.93) and individuals identified with osteoporosis had 32% more chances of stay (OR = 0.74, 95% CI, = 0.60-0.91). Only 1% of subjects remained until the end of the cohort. The stay rate was low throughout all series; the period with higher quitting rates was the 3 rd and the 12 th months, being associated with the female stay sex and undiagnosed osteoporosis.Key words: Motor Activity; Older adults; Survival analysis. 58,1% (IC95% = 54,3), com Estimativa de Risco = 41,82%. O sexo feminino apresentou chance de permanência de 45% (OR = 0,69; IC95% = 0,93) e os sujeitos identificados com osteoporose apresentaram 32% mais chances de permanência (OR = 0,74; IC95% = 0,91 Resumo -A matrícula ou inserção de idosos em Programas Comunitários de Atividade Física não garante sua permanência ao longo do tempo.

O presente estudo teve como objetivo identificar à prevalência de risco cardiovascular de acordo com índices antropométricos e avaliar à qualidade de vida em idosas participantes de grupos comunitários de prática de atividade física. Trata-se de um estudo com delineamento transversal, com amostra por conveniência. A amostra foi constituída por 84 idosas com média de idade 66,66 ± 5,54 anos. Aplicou-se instrumento compilado a partir de questionários validados para o Brasil. Também coletou-se os dados de massa corporal, estatura e circunferências de cintura, quadril e abdômen. Foram analisadas as variáveis sociodemográficas, percepção de qualidade de vida, nível de atividade física e a avaliação dos índices antropométricos índice de massa corporal e relação cintura/quadril. Enquanto principais resultados, verifica-se que 64,6% dos idosos são ativos, à circunferência de cintura classifica 79,48% dos idosos como "risco" e não houve diferença entre a percepção de qualidade de vida e à exposição ao risco identificado pelos índices antropométricos (F(3,71)= 0,31; p= 0,82). Conclui-se que a circunferência de cintura foi o índice antropométrico que melhor estimou o risco do grupo e que a percepção de qualidade de vida independe da estimativa de risco a qual o sujeito está exposto.Palavras-chave: idoso, obesidade, qualidade de vidaThe present study aimed to identify the prevalence of cardiovascular risk according to anthropometric indices and to evaluate the quality of life in elderly women participating in community groups of physical activity practice. It is a cross-sectional study, with convenience sample. The sample consisted of 84 elderly women with a mean age of 66.66 ± 5.54 years. An instrument compiled from questionnaires validated for Brazil was applied. Data were also collected on body mass, height and circumferences of waist, hip and abdomen. sociodemographic variables, perception of quality of life, level of physical activity and evaluation of anthropometric indices, body mass index and waist / hip ratio were analyzed. The main results show that 64.6% of the elderly are active, waist circumference classifies 79.48% of the elderly as "risk" and there was no difference between the perception of quality of life and the risk exposure identified by the anthropometric index (F (3,71) = 0.31, p = 0.82). It was concluded that waist circumference was the anthropometric index that best estimated the risk of the group and that the perception of quality of life independent of the risk estimate to which the subject is exposed.Keywords: elderly, obesity, quality of life INTRODUÇÃOA transição demográfica (TD), caracterizada pelo aumento da expectativa de vida, redução da taxa de fecundidade e consequente aumento da proporção de idosos em relação aos mais jovens, tem se configurado como um fator preocupante entre os países desenvolvidos e em desenvolvimento [1]. Essa preocupação se dá devido às alterações que ocorrem na previdência social e no alto custo financeiro despendido na saúde especializada, tendo em vista que um idos...
