Engagement in physical activity (PA) depends on intrapersonal, interpersonal/cultural, organizational, physical environment and political factors. Considering that it is important to understand this phenomenon in different populational contexts, this study aimed to investigate the factors related to engagement in PA according to sociodemographic aspects, eating habits, self-rated health, activities of daily living, noncommunicable diseases, mental health and public policies in Brazilian older people. This study had a cross-sectional design and used data from the Brazilian National Health Survey, 2019. Sample size was composed of 22,726 participants, aged 60 years or older, of both sexes, and all the data were collected by interview/questionnaire. According to the adjusted logistic regression, males were more active than females (OR = 1.59 (95% CI 1.40–1.80)), and those living in northern and northeastern Brazil were more likely to be inactive when compared to the southeastern region. Moreover, those with a higher educational level and income (OR = 1.36 (1.06–1.73) and OR = 1.60 (1.22–2.11)); with healthy eating habits (OR = 1.05 (1.03–1.06)); with positive self-rated health (OR = 2.67 (95% CI 1.51–4.71)); with better functional autonomy (OR = 1.22 (1.17–1.27)); and who reported that there was some public place (square, park, closed street, beach) to go for a walk, exercise or practice sport close to their home were more likely to be active (OR = 1.49 (1.34–1.67)). Sociodemographic factors, healthy eating habits, positive self-rated health, higher functioning in activities of daily living and living close to places where PA is practiced were associated with regular engagement in PA (i.e., ≥150 min/week).

Atividades físicas têm importante efeito profilático contra doenças cardiovasculares, pois promovem redução do peso corporal e níveis pressóricos, por exemplo. Indivíduos que desenvolvem trabalhos administrativos têm tendência ao sedentarismo, com consequente risco de obesidade. No entanto, a relação entre medidas antropométricas e hemodinâmicas ainda é inconsistente. Assim, o objetivo deste trabalho foi analisar a correlação entre parâmetros antropométricos e hemodinâmicos de servidores públicos. É um estudo observacional e transversal com uma amostra de 147 indivíduos. Verificou-se que homens normotensos apresentaram maiores médias de índice de massa corporal em relação aos hipertensos. Em contrapartida, esses indivíduos demonstraram maiores valores de frequência cardíaca em repouso. Notou-se que nenhuma das variáveis antropométricas foi associada à pressão arterial sistólica e diastólica, observando-se apenas associações das variáveis antropométricas entre si (r = 0,738 - peso corporal e quadril; e r = 0,936 - abdômen e circunferência de cintura). Portanto, não se observou associações entre variáveis antropométricas, índices pressóricos e frequência cardíaca de repouso. Conclui-se que, apesar das variáveis antropométricas serem boas preditoras de adiposidade corporal, não necessariamente são relacionadas com variáveis hemodinâmicas. A prática de atividade física deve ser estimulada dentro das rotinas laborais, em momentos oportunos, buscando incentivo a hábitos saudáveis e melhoria dos indicadores antropométricos.

This study aimed to analyze the impact of cardiovascular diseases (CVDs) on life expectancy (LE) in the Brazilian population; and to identify how the hypothetical reduction in mortality from 5 to 30%, as well as the hypothetical scenario with no deaths (i.e., elimination) of these diseases would affect LE. This is a simulation study using national cross-sectional data. To identify the impact of CVDs on LE, we used multiple decrement life table models, considering hypothetical CVDs reductions in mortality from 5 to 30% and their elimination. The estimated overall potential gains in LE [years (%)] from the elimination of ischemic disease, hypertensive disease, and cerebrovascular disease were 1.44y (2%) and 1.31y (1.7%), 0.51y (0.7%) and 0.75y (1%), and 1.28y (1.8%) and 1.62y (2.1%), for males and females, respectively. The largest gains in LE were observed among those who live in Brazil's Northeast region. For the overall population, the estimated gains in LE linked to a 5% reduction in CVD mortality for males and females were 0.07y (0.1%) and 0.06y (0.08%) for ischemic disease, 0.02y (0.03%) and 0.04y (0.05%) for hypertensive disease, and 0.06y (0.08%) and 0.07y (0.09%) for cerebrovascular disease. A hypothetical decrease of 30% in mortality by CVDs would lead to gains in LE, for males and females, of 0.41y (0.6%) and 0.37y (0.5%) for ischemic disease, 0.15y (0.2%) and 0.22y (0.3%) for hypertensive disease, and 0.36y (0.5%) and 0.45y (0.6%) for cerebrovascular disease. Thus, investment towards improving CVDs, including CVD prevention efforts, would increase LE in Brazil, especially in less developed regions.

Introducao: Em 1977, na cidade de Winnipeg no Canada, surge o Rugby em Cadeira de Rodas (RCR). Ja no Brasil, a modalidade iniciou-se no ano de 2005 no Rio de Janeiro (RJ). A equipe brasileira com maior numero de titulos nacionais (4 titulos) surge no ano de 2008 em Campinas-SP. Dessa forma, podemos verificar que a modalidade do RCR e recente, possibilitando diversos estudos na area. Com o intuito de aumentar a gama de conhecimento na modalidade o presente estudo teve o objetivo de analisar os niveis de forca muscular em atletas de RCR. Metodologia: Este estudo caracteriza-se como pesquisa descritiva e apresenta um delineamento transversal. A amostra foi composta por 10 atletas (homens) com lesao da medula espinhal (LME) em nivel cervical (tetraplegia) com media de idade de 31,1±5,06 anos. Os atletas foram recrutados na equipe de Rugby em Cadeira de Rodas do Projeto de Atividade Motora e Esporte Adaptado da Universidade Estadual de Campinas (ADEACAMP/UNICAMP). Para analisar os niveis de forca muscular isometrica, foi utilizado o Handheld Dynamometer (HHD; mTas F-1; ANIMA, Tokyo, Japao) e para avaliacao da espessura muscular foi utilizado o Ultrassom da marca SonoSite® (HDI-3000, ATL, Bothell, Washington, EUA), utilizando 7,3 MHz da sonda linear-matriz. Resultados: Para forca muscular isometrica maxima no movimento de Flexao do Ombro Direito (FOD) a media e desvio padrao, respectivamente foram 322.80±119.89 (N), para Flexao de Ombro Esquerdo (FOE) foram 319.60±127.58 (N), para Extensao do Ombro Direito (EOD) foram 129.80±54.68, para Extensao do Ombro Esquerdo (EOE) 139.30±67.48 (N), para Flexao do Cotovelo Direito foram 189.20±37.85 (N), para Flexao do Cotovelo Esquerdo (FCE) foram 192.30±35.56 (N), para Extensao do Cotovelo Direito (ECD) foram 72.30±72.79 (N) e para Extensao do Cotovelo Esquerdo (ECE) foram 69.40±66.84 (N).

Abstract

Background Osteoarthritis (OA) is a chronic degenerative disease which can result in chronic pain, loss of joint function and consequently decline in quality of life. Research question A variety of instruments that measure the different dimensions of health status in patients with OA are available. However, despite the fact that WOMAC and other questionnaires and scales may provide additional understanding regarding the patient’s condition, some studies have reported discrepancies between patients’ perceptions and their actual ability to perform the task. The aim of the present study was investigate the physical capabilities with the function domain of WOMAC. Methods This study has a cross-sectional design including patients diagnosed with moderate to severe knee OA (i.e., grades II, III and IV) according to the Kellgren-Lawrence. These patients were submitted to the battery of functional tests recommended by the OARSI group (30-second chair stand test, 40 meters fast paced walking test, Stair climb test, timed “Up and Go”, and Six-minute walking test) and filled the WOMAC. Pearson’s correlation and multiple linear regression was applied. Results A total of 153 patients were included. A significant and weak correlation was observed between WOMAC and the 40-meter walking test, TUG, stair-climbing test, and the 6MWT. In addition, 30-second chair stand test demonstrated a significant and moderate correlation (r=-0.503). The multiple regression analysis results indicated that only 30-second chair stand test was a significant (p = 0.001) predictor of WOMAC. This result remains significant even after adjusting for age, BMI, total muscle mass, and number of knees affected Significance The 30-second chair stand test is associated with the WOMAC function domain. There is no correlation of this domain with any other functional tests, emphasizing the importance of including other tests for a global evaluation.

Introduction: Evidence suggests that populations of developing countries present high levels of sedentarism. In contrast, it is also shown that educational level and access to information regarding the health benefits of exercise can raise a population’s level of physical activity (LPA). Thus, the present study aimed to evaluate the morphological profile (MP), level of physical activity (LPA) and cardiovascular risk among Brazilian (BPES) and Colombian physical education students (CPES) in an effort to determine if these specific subjects presented different results among themselves and in relation to normative data for each country. Method: The subjects, 59 BPES and 65 CPES, were evaluated through IPAQ in its short form, and had their MP determined through a bioelectric scale and waist measurement to determine the cardiovascular risk. Results: As result we verified that between BPES and CPES only waist circumference (WC) had significant difference (p = 0.016), being higher for CPES males. Comparing the results of the subjects with normative data, with the exception of CPES males, we observed higher LPA, better MP, and lower WC values. Female CPES were more active than their male peers, the opposite being true for the Brazilian subjects. Conclusion: We conclude that the repetitive exposition to information regarding the benefits of physical activity and the access to installations that allows for its practice not only raises LPA of physical education students, but also improves, in general, their MP and cardiovascular risk.

Background Strength training (ST) is commonly used to improve muscle strength, power, and neuromuscular adaptations and is recommended combined with runner training. It is possible that the acute effects of the strength training session lead to deleterious effects in the subsequent running. The aim of this systematic review and meta-analysis was to verify the acute effects of ST session on the neuromuscular, physiological and performance variables of runners. Methods Studies evaluating running performance after resistance exercise in runners in the PubMed and Scopus databases were selected. From 6532 initial references, 19 were selected for qualitative analysis and 13 for meta-analysis. The variables of peak torque (PT), creatine kinase (CK), delayed-onset muscle soreness (DOMS), rating of perceived exertion (RPE), countermovement jump (CMJ), ventilation (VE), oxygen consumption (VO2), lactate (La) and heart rate (HR) were evaluated. Results The methodological quality of the included studies was considered reasonable; the meta-analysis indicated that the variables PT (p = 0.003), DOMS (p p p 2, La, FC there was no difference. By qualitative synthesis, running performance showed a reduction in speed for the experimental group in two studies and in all that assessed time to exhaustion. Conclusion The evidence indicated that acute strength training was associated with a decrease in PT, increases in DOMS, CK, RPE and had a low impact on the acute responses of CMJ, VE, VO2, La, HR and submaximal running sessions.

O objetivo deste estudo foi verificar a influência da caminhada em variáveis cognitivas e antropométricas de mulheres idosas. Foram recrutadas 30 mulheres destreinadas, sem doenças neurodegenerativas, com média de idade de 64,40 ± 3,71 anos, divididas por conveniência em grupo de intervenção (n = 16) e controle (n = 14). O grupo de intervenção foi submetido à prática de jogos desportivos, caminhada e alongamento, em ambientes abertos, durante três meses, duas vezes por semana. O grupo controle não participou de nenhum programa de atividade física. Antes e após a intervenção, todas as idosas foram submetidas aos testes Códigos WAIS-III, Color Trail Test (CTT-A e CTT-B), e medidas de massa corporal e estatura (determinação do índice de massa corporal – IMC), circunferência da cintura e do quadril (razão cintura-quadril – RCQ). O grupo de intervenção melhorou o desempenho no teste Códigos WAIS-III (Δ = 8,68; IC95%: 6,7; 10,7) e reduziu os tempos de execução dos testes CTT-A (Δ = -7,94; IC95%: -13,1; -2,8) e CTT-B (Δ = -18,59; IC95%: -31,4; -5,8). As modificações do grupo controle não foram estatisticamente significativas (p > 0,05). Conclui-se que a prática de caminhada pode melhorar habilidades cognitivas de mulheres idosas destreinadas.

The objective of this systematic review was to identify the association between overweight/obesity and level of physical activity in Brazilian children and adolescents in the school setting. For search strategy, the main reference databases (PubMed, LILACS, SciELO, SPORTDiscus, Web of Science, ERIC) were used. Baseline searches resulted in 3,265 potentially relevant titles (2,775 titles after removal of duplicate studies); 21 studies met all inclusion criteria and were included for analysis. Studies were carried out from 2007 to 2019; 47.6% of them were conducted in Southern Brazil, and only one study had nationwide approach. Prevalence from 5.4% to 21% was identified for overweight, 3.5% to 16.9% for obesity and 11.8% to 40.1% for overweight + obesity. According to results, 64.3% of overweight, 69.8% of obese and 37.7% of young overweight people were considered insufficiently active. The non-standardization of instruments to assess levels of physical activity and the lack of information regarding other Brazilian regions were classified as important limitations. The results reinforce the increase in the prevalence of overweight in Brazilian children and adolescents, and the high prevalence of physical inactivity among them. For every ten overweight children/adolescents, six are reported to be insufficiently active. O objetivo desta revisão sistemática foi identificar a associação entre excesso de peso, obesidade e nível de atividade física em crianças e adolescentes brasileiros, no ambiente escolar. A busca eletrônica foi realizada nas principais bases de dados de referência (PubMed, LILACS, SciELO, SPORTDiscus, Web of Science, ERIC). A pesquisas nas bases resultaram em 3265 títulos potencialmente relevantes (2775 títulos após análise duplicada); 21 estudos preencheram todos os critérios de inclusão e foram analisados. Os estudos foram realizados entre 2007 e 2019, 47,6 % deles foram realizados no sul do Brasil, e apenas uma pesquisa foi realizada a nível nacional. Foi identificado prevalências de 5,4% a 21% para sobrepeso, 3,5% a 16,9% para obesidade e 11,8% a 40,1% para excesso de peso (obesidade + sobrepeso). De acordo com os resultados, 64,3% dos jovens com sobrepeso, 69,8% dos obesos e 37,7% daqueles com excesso de peso foram considerados insuficientemente ativos. A não padronização dos instrumentos para avaliar os níveis de atividade física e a pouca representatividade de outras regiões brasileiras foram classificadas como lacunas importantes. Os resultados reforçam o aumento da prevalência de excesso de peso em crianças e adolescentes no Brasil, e a alta prevalência de inatividade física entre estes jovens. A cada dez jovens acima do peso, seis são insuficientemente ativos.

Resumo: Introdução: A educação interprofissional (EIP) desenvolve competências colaborativas, aprimora a segurança do paciente e melhora a qualidade da atenção à saúde. A disponibilidade para aprendizagem compartilhada relaciona-se diretamente com a EIP. Objetivo: Este estudo teve como objetivo analisar a disponibilidade dos estudantes para a EIP, de acordo com os ciclos e cursos. Método: Trata-se de estudo transversal, descritivo, de abordagem quantitativa. Utilizou-se a Readiness for Interprofessional Learning Scale (RIPLS) via formulário eletrônico. Os testes Mann-Whitney e qui-quadrado foram utilizados para analisar respectivamente variáveis contínuas e categóricas. Nas análises para verificar as diferenças nas pontuações dos fatores 1. trabalho em equipe e colaboração (TEC), 2. identidade profissional (IP) e 3. atenção à saúde centrada no paciente (ACP), além da pontuação global da RIPLS, os cursos e ciclos foram comparados por meio do teste Kruskal-Wallis. Resultado: Participaram do estudo 506 estudantes, com taxa de respostas de 32,6%, dos cursos de Enfermagem, Farmácia, Fisioterapia, Fonoaudiologia, Medicina, Nutrição, Odontologia e Terapia Ocupacional de uma universidade pública brasileira. As pontuações dos fatores 1, 2 e 3 e a pontuação global da RIPLS não apresentaram diferenças entre os sexos. Os estudantes do curso de Farmácia apresentaram menor disponibilidade para o fator 3 (ACP) quando comparados com os alunos de Enfermagem, Fisioterapia, Medicina, Odontologia e Terapia Ocupacional (p = 0,007). Os discentes de Fonoaudiologia e Nutrição apresentaram menor pontuação no mesmo fator em comparação com os de Odontologia e Terapia Ocupacional (p = 0,007). Os estudantes de Farmácia (p = 0,004) e Medicina (p = 0,016) foram menos propícios a obter maior pontuação no fator 1 (TEC), enquanto os de Terapia Ocupacional obtiveram maior chance para maior disponibilidade no mesmo fator (p = 0,024). No fator 2 (IP), os estudantes do quinto ciclo foram menos propensos a atitudes positivas (p = 0,046). Observou-se que os estudantes de Terapia Ocupacional apresentaram atitude mais favorável para a EIP expressa tanto no fator 3 (p = 0,034) quanto na pontuação global (p = 0,027), enquanto os alunos do curso de Farmácia apresentaram menor chance para melhor disponibilidade no fator 3 (p = 0,003) e na pontuação global (p = 0,003). Conclusão: Considerando a relevância da EIP no processo de reorientação da formação de profissionais de saúde para a construção da integralidade do cuidado e alinhamento com o Sistema Único de Saúde, este estudo pretende contribuir para a reflexão acerca das diferenças na disponibilidade para EIP entre cursos de graduação na área da saúde. Abstract: Introduction: Interprofessional Education (IPE) helps develop collaborative skills, enhance patient safety and improve the quality of health care. Readiness for shared learning is directly related to IPE. Objective: To analyze Readiness for IPE among students, according to the cycles and courses. Method: This cross-sectional, descriptive study adopted a quantitative approach and used the Readiness for Interprofessional Learning Scale (RIPLS) via an electronic form. Mann-Whitney and chi-square tests were used to analyze the continuous and categorical variables, respectively. Analyses to ascertain differences between scores for the factors (1) Teamwork and Collaboration (TEC), (2) Professional Identity (IP), (3) Patient-Centered Health Care (ACP), and the overall RIPLS score, used the Kruskal-Wallis test to compare courses and cycles. Result: A response rate of 32.6% was attained from a sample of 506 students from the Nursing, Pharmacy, Physiotherapy, Speech Therapy, Medicine, Nutrition, Dentistry and Occupational Therapy courses of a Brazilian public university. The scores for factors 1, 2 and 3, and the overall RIPLS score did not differ between genders. Pharmacy students reported a lower Readiness for factor 3 (ACP) compared to students in Nursing, Physiotherapy, Medicine, Dentistry and Occupational Therapy (p=0.007). Speech therapy and Nutrition reported lower scores for the same factor compared to Dentistry and Occupational Therapy (p=0.007). Pharmacy students (p=0.004) and medicine students (p=0.016) were less likely to obtain a higher score in factor 1(TEC), while Occupational Therapy students were more likely to report greater Readiness in the same factor (p=0.024). In factor 2 (IP), fifth grade students were less likely to have positive attitudes (p=0.046). It was observed that Occupational Therapy students showed a more favorable attitude towards IPE expressed both in factor 3 (p=0.034) and in the overall score (p=0.027), while students in the Pharmacy course were less likely to report better readiness in factor 3 (p=0.003) and in the overall score (p=0.003). Conclusion: Considering the relevance of IPE in the process of redirecting health care training to build comprehensive care and ensure alignment with the Unified Health System, this study aims to reflect on the differences in readiness for IPE between undergraduate courses in health area.

Background and purpose Although combining classical resistance (RT) and power training (PT) might be an efficient strategy to achieve optimal enhancements in body composition and physical function in older adults, the most effective approach to combine these different types of exercise training is still unknown. Periodization, an organizational model that refers to a succession of cycle that will vary in exercise intensity and/or volume to allow for the training stimulus to remain biologically challenging and effective, may represent an interesting approach. Among the different types of periodization, daily undulating periodization (DUP) has attracted considerable attention given its superiority in comparison to nonperiodized (NP) RT programs to elicit neuromuscular improvements in young adults. However, whether a DUP program combining PT and traditional RT can produce similar or greater improvements in body composition and physical function in older adults than a NP RT program has not yet been established. Therefore, the present study compared the effects of a DUP and NP programs on body composition and physical function in healthy community-dwelling older women. Methods Forty-two older women (60–79 years) were randomized into one of the three experimental groups: NP, DUP, and control group (CG). Body composition and physical function were assessed at baseline and after the intervention. The sessions of exercises were performed twice a week over 22 weeks. In NP, the two exercise sessions were based on three sets of 8–10 repetitions at a “difficult” intensity (i.e., 5–6) prescribed based on the Rating of Perceived Exertion (RPE) scale. In DUP, the first session was based on PT (three sets of 8–10 repetitions at a “moderate” intensity, i.e., 3, performed as fast as possible), while the second session was similar to the NP. Results There were no significant changes in body composition in any of the groups. Relative to baseline, participants assigned to NP showed significant improvements in countermovement jump (+55.7%), timed “Up and Go” (TUG) test (−43.2%, faster), walking speed (+12.0%), and one-leg-stand (+154.5%). In contrast, DUP only improved TUG performance (−53.2%, faster). Conclusion NP and DUP improved physical function in community-dwelling older women, with greater improvements in physical parameters only observed after NP.

Purpose To compare the effects of exergames versus conventional physical training on the cognitive skills of older adults. Materials and Methods Scientific studies published in PubMed, Web of Science, and Cochrane Library databases were searched. Individual studies were assessed using the Cochrane Risk-of-bias tool for randomized trials (RoB 2). The quality of evidence was evaluated using the Grading of Recommendations, Assessment, Development and Evaluations (GRADE Pro). The cognitive outcomes were Trail Making Test (TMT)-A, TMT-B, Stroop Word-Color test, Mini Mental State Examination (MMSE), and Montreal Cognitive Assessment (MoCA). Results We identified 256 studies, in which 13 studies were included in the systematic review and 11 in the meta-analysis. The majority of the exergame interventions were based on the Xbox 360′s Kinect, followed by the Impact Dance Platform, Nintendo Wii, and the Bike Labyrinth. We observed heterogeneity in the conventional exercise group and in the duration of training, which ranged from 12 to 52 sessions. There was no statistically significant difference between groups in TMT-A (p=0.083), TMT-B (p=0.122), and Stroop (p=0.191). There were differences in favor of exergames in MMSE (raw mean difference=-1.58, 95% CI: -2.87 to -0.28, p Conclusions Despite statistical differences in MMSE and MoCA, these results should be interpreted with caution due to methodological heterogeneity. Some studies reported possible neurophysiological benefits induced by exergames, which should be explored in future investigations.

The aim of this study was to identify evidence regarding associations between School Physical Activity (PA) and Mental Health (MH) in Brazilian school-aged adolescents. This is a systematic review study. Studies were selected in Portuguese and English and identified by a systematic search in six electronic databases: PubMed, Web of Science, SPORTDiscus / Ebsco, ScIELO, ERIC, and LILACS, which comprised publications until 2019. Inclusion criteria were: studies with cohort, descriptive, cross-sectional or qualitative design; performed with children and adolescents; studies that analyzed the relationship between PA and MH; studies that investigated adolescents who practiced PA in schools; studies carried out in Brazil; and studies that reached minimum of 60% of methodological quality criteria according to STROBE. Physical education, as curricular activity in basic education, has protective effect on MH in the school setting. In addition, more than 300 min/week of PA was positively associated with MH; while associations between PA and excessive TV time; social isolation; and body weight dissatisfaction were negatively associated. School PA is positively associated with MH as it promotes physical and psychological well-being, impacting on the reduction of insomnia rates, attenuating loneliness and improving physical appearance. RESUMO Objetivou-se identificar a evidência quanto às associações entre atividade física (AF) e saúde mental (SM) em adolescentes escolarizados brasileiros. Trata-se de um estudo de Revisão Sistemática. Os estudos foram selecionados em português e inglês e identificados por meio de uma busca sistemática em seis bases de dados eletrônicas: PubMed, Web of Science, SPORTDiscus/Ebsco, ScIELO, ERIC, e LILACS, que compreendeu publicações até o final de 2019. Os critérios de inclusão foram: estudos com um desenho de coorte, descritivo de caráter exploratório, transversal, ou qualitativos; realizados com crianças e adolescentes; estudos que analisaram a relação entre AF e SM; estudos que investigaram adolescentes que praticavam AF nas escolas; estudos realizados no Brasil e os que obtiveram a pontuação mínima estabelecida de 60% conforme os critérios da qualidade metodológica do instrumento STROBE. A Educação Física oferecida no currículo da educação básica tem um efeito protetor sobre a SM no ambiente escolar. Além disso, mais de 300 min/semana de AF foi associado positivamente com a SM. Algumas associações foram negativas entre a AF e a SM, tais como: tempo excessivo de TV; isolamento social; insatisfação com o peso corporal. A AF escolar está associada positivamente à SM por promover bem-estar físico e psicológico, impactando na redução dos índices de problema de insônia, atenuando a solidão e melhorando a aparência física.

Aim: This study aimed to examine the association between physical activity (PA) indicators and TV viewing as a function of the Human Development Index (HDI). Method: This cross-sectional study was based on data from the National School Health Survey, which was composed of 102,072 students (14.28±1.03; 51.3% girls). Total PA, active commuting to school (ACS) and TV viewing were assessed by questionnaires and classified through a gradual scale ranging from “F” (low) to “A+” (high). The correlation between total PA, ACS, TV viewing and HDI was verified by Spearman’s Correlation and presented in rs. Results: HDI was positively associated with total PA [girls: rs = 0.572 (p < 0.001); boys: rs = 0.843 (p < 0.001)] and ACS [girls: rs = 0.433 (p < 0.001); boys: rs = 0.554 (p < 0.001)]; while a negative correlation was found between HDI and TV viewing [girls: rs = -0.330 (p < 0.001); boys: rs = -0.348 (p < 0.001)]. Conclusions: Brazilian adolescents from states with higher HDI were more active and spent more time watching TV than their counterparts from states with lower HDI.

Descrever a distribuição do autorrelato de asma e identificar os fatores associados em escolares brasileiros, conforme região e sexo. Trata-se de um estudo transversal, utilizando dados da Amostra 1, da PeNSE 2015 (n = 95387). Para a análise descritiva, utilizou-se as medidas de frequência absoluta e relativa. Para a verificação dos fatores associados à asma em adolescentes brasileiros, utilizou-se a regressão logística binária, assumindo o seguinte modelo hierárquico: Bloco Sociodemográfico: Sexo, idade, raça; Bloco Ambiental: Região, tipo de município; Bloco Comportamental: Consumo de tabaco, nível de atividade física, sendo utilizado como desfecho a variável “asma alguma vez na vida”, analisando a resposta da questão “Você teve asma alguma vez na vida?”. Verifica-se maior prevalência de episódio de asma autorrelatado no sexo feminino (51,7%), observando-se maior chance deste autorrelatar asma (OR=1,07; IC95% 1,03-1,11) em relação ao sexo masculino. Não residir em capital apresentou 28% menos chances de autorrelatar asma (OR=0,78; IC95% = 0,75-0,80) e o adolescente não asmático tem 12% menos chance de ser ativo (OR=0,88; IC95% = 0,85-0,91). A prevalência de episódio autorrelatado de asma é menor para os residentes na Região Centro-Oeste. Contudo, é maior entre o sexo feminino, no adolescente que mora nas capitais brasileiras, verificando-se que o adolescente asmático tende a ser mais ativo que seus pares.

The present study compared the effects of traditional resistance training (TRT) and combined power training (PT) and TRT (PTRT) on cognitive parameters and serum brain-derived neurotrophic factor (BDNF) levels in non-demented, well-functioning, community-dwelling older women. Forty-five older women were randomized into one of three experimental groups: TRT, PTRT, and control group (CG). Cognitive tests explored global cognitive function, short-term memory, and dual-task performance. Serum BDNF levels were assessed at baseline and after the intervention. Exercise sessions were performed twice a week over 22 weeks. In TRT, exercise sessions were based on three sets of 8&ndash, 10 repetitions at &ldquo, difficult&rdquo, intensity. In PTRT, the first session was based on PT (three sets of 8&minus, moderate&rdquo, intensity), while the second session was similar to the TRT. Our analyses indicated that overall cognitive function, short-term memory, and dual-task performance were similarly improved after TRT and PTRT. Serum BDNF concentrations were not altered by any training protocol. In conclusion, the two RT programs tested in the present trial improved global cognitive function, short-term memory and dual task performance in non-demented, well-functioning, community-dwelling older women. In addition, our findings suggest that mechanisms other than BDNF may be associated with such improvements.

Aging comprises a dynamic and progressive process, characterized by physiological and functional changes. Among these changes, increase in body fat is considered relevant, since it can leads to impaired physical fitness and augmented cardiometabolic risks. Considering this, the objective of this study was to evaluate the influence of overweight on functional capacity of physically active older women. A field survey was performed with 24 older women who practiced physical exercise. Participants were submitted to anamnesis, anthropometric measures (i.e., body mass and height); the Senior Fitness test; sit and reach flexibility test; and handgrip strength test. Pearson’s correlation test and multivariate logistic regression were used to verify the association between overweight and functional capacity. It was observed that hip flexibility (R=-0.494, p=0.014) and flexibility of the lower limbs (i.e., sit and reach test) showed negative correlation with the body mass index (R=-0.446, p=0.02); and after the multivariate logistic regression, negative correlation of lower limbs flexibility (B= -0,035, p=0,014) and the body mass index was observed. Thus, higher the body mass index among participants, lower hip flexibility they presented. O envelhecimento compreende um processo dinâmico e progressivo. Caracteriza-se por alterações fisiológicas e funcionais, sendo a modificação na composição corporal com o acréscimo de gordura corpórea considerada relevante, podendo ocasionar comprometimento da aptidão física e alterações cardiometabólicas. O objetivo deste estudo foi avaliar a influência do sobrepeso na capacidade funcional em idosas praticantes de exercício físico. Foi realizada uma pesquisa de campo correlacional com 24 idosas praticantes de exercício físico. Todas as idosas foram submetidas à anamnese, análise antropométrica com avaliação da massa corporal e estatura, capacidade funcional com a bateria de testes de Rikli e Jones (Sênior Fitness test), flexibilidade com o banco de Wells e força de preensão manual com o teste de preensão manual. Utilizou-se o teste de correlação de Pearson e a regressão logística multivariada pelo método Stepwise para verificar a associação entre sobrepeso e capacidade funcional. Observou-se que a flexibilidade de Quadril (R=-0,494, p=0,014) e a flexibilidade dos membros inferiores pelo banco de Wells (R=-0,446, p=0,02) apresentaram forte correlação negativa com o índice de massa corporal (IMC). Após a regressão logística multivariada, percebeu-se uma forte correlação negativa com a flexibilidade do quadril (B=-0,035, p=0,014). Assim, a flexibilidade do quadril entre as idosas ativas com sobrepeso reduziu com o aumento do IMC.

Introdução: O teste de Stroop é comumente utilizado para avaliar a flexibilidade cognitiva e função executiva. O teste mostrou correlacionar-se com variáveis como idade, nível educacional e atividade física, porém, pouco se sabe sobre as variáveis relacionadas ao desempenho no teste em populações previamente ativas. Objetivo: Avaliar o desempenho no teste de Stroop em população fisicamente ativa. Métodos: 89 estudantes foram recrutados, os mesmos tiveram seus níveis de atividade física avaliado por questionário e composição corporal avaliada por bioimpedância. Resultado: Observamos que as variáveis relacionadas à prática de atividade física não apresentaram correlação com o teste de Stroop. Foi identificado correlação do teste com as variáveis peso corporal e índice de massa corporal (IMC), sendo que maiores valores de peso e IMC resultaram em melhor desempenho no teste. Conclusão: Para indivíduos fisicamente ativos, outros fatores parecem ser preponderantes à atividade física com relação ao desempenho no teste de Stroop.

CONTEXT AND OBJECTIVE: In elderly people, measurement of several anthropometric parameters may present complications. Although neck circumference measurements seem to avoid these issues, the cutoffs and cardiovascular risk factors associated with this parameter among elderly people remain unknown. This study was developed to identify the cutoff values and cardiovascular risk factors associated with neck circumference measurements among elderly people. DESIGN AND SETTING: Cross-sectional study conducted in two community centers for elderly people. METHODS: 435 elderly adults (371 women and 64 men) were recruited. These volunteers underwent morphological evaluations (body mass index and waist, hip, and neck circumferences) and hemodynamic evaluations (blood pressure values and heart rate). Receiver operating characteristic curve analyses were used to determine the predictive validity of cutoff values for neck circumference, for identifying overweight/obesity. Multivariate analysis was used to identify cardiovascular risk factors associated with large neck circumference. RESULTS: Cutoff values for neck circumference (men = 40.5 cm and women = 35.7 cm), for detection of obese older adults according to body mass index, were identified. After a second analysis, large neck circumference was shown to be associated with elevated body mass index in men; and elevated body mass index, blood pressure values, prevalence of type 2 diabetes and hypertension in women. CONCLUSION: The data indicate that neck circumference can be used as a screening tool to identify overweight/obesity in older people. Moreover, large neck circumference values may be associated with cardiovascular risk factors. RESUMO CONTEXTO E OBJETIVO: Em idosos, diversas ferramentas antropométricas podem apresentar complicações durante a mensuração. Embora a circunferência do pescoço pareça evitar tais problemas, os pontos de corte e fatores de risco cardiovascular associados a essa ferramenta em idosos permanecem desconhecidos. Este estudo foi desenvolvido para identificar os valores de ponto de corte e fatores de risco cardiovascular associados à circunferência do pescoço em idosos. DESENHO E LOCAL: Estudo transversal, realizado em dois centros comunitários para idosos. MÉTODOS: 435 idosos (371 mulheres e 64 homens) foram recrutados. Os voluntários foram submetidos a avaliação morfológica (índice de massa corporal e cintura, quadril, e circunferência do pescoço) e hemodinâmica (valores da pressão arterial e frequência cardíaca). A análise pela curva receiver operating characteristic foi usada para determinar o valor preditivo dos valores de ponto de corte da circunferência do pescoço para identificação de sobrepeso/obesidade. Análise multivariada foi usada para identificar os fatores de risco cardiovascular associados com circunferência do pescoço larga. RESULTADOS: Os valores de corte para circunferência do pescoço (homens = 40,5 cm e mulheres = 35,7 cm) para detectar adultos idosos obesos, de acordo com o índice de massa corporal, foram identificados. Depois da segunda análise, circunferência do pescoço larga foi associada com elevado índice de massa corporal em homens e mulheres e elevados valores de pressão arterial, prevalência de diabetes mellitus tipo II e hipertensão em mulheres. CONCLUSÃO: Os dados indicam que a circunferência do pescoço pode ser utilizada como ferramenta de rastreio para identificar sobrepeso/obesidade em idosos. Ademais, altos valores de circunferência do pescoço podem estar associados com fatores de risco cardiovascular.

Objective: The aim of the study was to compare physical fitness, quality of life and domains of frailty between physically frail and robust older women, whose was classified by the physical domain from Kihon Checklist. Method: One hundred and thirty-two community-dwelling older women participated in the study (68.5 ± 6.1 years). Data were collected through questionnaires (sociodemographic, Kihon Checklist, Short Form-8 items) and physical and functional tests. Results: Most frail older women lived alone (P

Aim To investigate whether the Kihon Checklist (KCL) can predict frailty and disability. Methods The studies analyzed for the present review were retrieved by searching electronic databases and other sources using the keywords “Kihon Checklist” and “Basic Checklist.” The articles were restricted to those written in English and published in health sciences journals from the year 2006 until the end of April 2015. To be included in the full analysis, the study had to be primary research and use the KCL as a dependent or independent variable. Results A total of 62 articles were identified in the initial search, and after screening, 13 articles were included in this review. The KCL was found to be closely correlated with validated assessments of frailty phenotypes. The complete version of the KCL and specific domains have been used as research outcomes to verify frailty in cross-sectional and longitudinal studies. KCL domains were applied to evaluate different outcomes, such as depressive mood, functional disability and instrumental activities of daily living limitations. Conclusions The KCL is a reliable tool for predicting general frailty and frailty aspects in older adults. The KCL was shown to be adequate for cross-cultural studies and to be suitable for addressing frailty demands among elderly in multiple cohorts. The KCL is a short questionnaire, which makes its administration by health promoters easy; thus, it has been used to evaluate the effectiveness of frailty interventions. We strongly recommend use of the KCL in community and clinical practice to assess frailty status. Geriatr Gerontol Int 2016; 16: 893-902.

[Purpose] The aim of this technical note was to report significant differences in the tension forces of the different-sized Thera-band(®) elastic bands (Hygenic Corp.) determined by us versus the manufacturer. [Subjects] Two trained observers performed all measurements. [Methods] The tension force (kilogram-force units) of eight color-coded elastic bands (tan, yellow, red, green, blue, black, silver, and gold) with different resistance levels was measured at 10 different percentages of elongation (25% to 250% with 25% increments) using an electronic elongation gauge tensiometer. [Results] There were significant differences in the tension force of the elastic bands of different colors when compared in pairs (excepting the tan/yellow pair) at 100% and 200% elongation, as determined via one-way analysis of variance. There were no differences in the slopes for the tan versus yellow and green versus blue bands, as determined via linear regression analysis and one-way analysis of variance. Comparison of the tension force values obtained in our study with the reference values of the manufacturer (the t-test applied to the slopes) showed significant differences for five colors (yellow, green, blue, silver, and gold). [Conclusion] Our results indicate that the tension force values for Thera-Band elastic bands provided by the manufacturer are overestimates.

AIM: To investigate the lifestyles, physical performance and quality of life (QOL) of frail and robust Brazilian community-dwelling older women, and to identify risk factors for frailty. METHODS: Frailty was assessed using the Kihon Checklist. Lifestyles were assessed using a questionnaire. Physical performance was assessed by measuring walking speeds, performance on the one-leg stand test and the five-times chair stand test and handgrip strength. QOL was assessed using the Short Form-8 questionnaire. Participants were divided into frail and robust groups based on their total Kihon Checklist scores. RESULTS: A total of 109 participants (age 70.8 ± 6.87 years) were included in this study (robust n = 85, frail n = 24). Differences in living structures (P CONCLUSIONS: Frail participants had higher indices for being housebound, and having financial dissatisfaction, a sedentary lifestyle, falls, and malnutrition. Furthermore, they showed poorer physical performance and QOL. An early, well-focused approach is crucial, especially for older adults who walk slowly and have bodily pain to preserve health and QOL.

Aim To investigate frailty in Japanese, Brazilian Japanese descendants and Brazilian older women. Methods The collected data included sociodemographic and health-related characteristics, and the frailty index Kihon Checklist. We analyzed the differences between the mean scores of Kihon Checklist domains (using ancova) and the percentage of frail women (using χ2-test). We carried out a binary logistic regression with Kihon Checklist domains. Results A total of 211 participants (Japanese n = 84, Brazilian Japanese descendants n = 55, Brazilian n = 72) participated in this research. The Brazilian participants had the highest total Kihon Checklist scores (more frail), whereas the Brazilian Japanese descendants had the lowest scores (P

[Background/purpose]Day care centers are rapidly expanding in Brazil to meet the needs of the increasing older population. However, health profiles of their clients remain unclear. Therefore, this study aimed to investigate and compare the health conditions of users and nonusers of a day care center using a new frailty index, the Kihon Checklist. [Methods]This was a cross-sectional observational study. We recruited 59 users (mean age 81.1 ± 6.69 years) and 173 nonusers (mean age 69.9 ± 7.39 years). The nonusers were recruited at a recreational club and municipal health units, and the users were recruited at a day care center for the elderly in Brazil. Measurements consisted of questionnaires regarding sociodemographic and health-related characteristics and the Kihon Checklist. [Results]Compared with the nonusers, users had a higher prevalence of frailty (p < 0.001) and impairment of all specific domains (instrumental activities of daily living impairment, p < 0.001; physical inactivity, p < 0.001; seclusion, p < 0.001; cognitive deficit, p < 0.001; and depression, p < 0.001). The users were also more likely to be frail [odds ratio (OR), 14.226; 95% confidence interval (CI), 5.423–37.320; p < 0.001], dependence in instrumental activities of daily living (OR, 78.845; 95% CI, 19.569–317.674; p < 0.001), physically inactive (OR, 3.509; 95% CI, 1.467–8.394; p = 0.005), cognitively impaired (OR, 5.887; 95% CI, 2.360–14.686; p < 0.001), and depressed (OR, 5.175; 95% CI, 2.322–11.531; p < 0.001) than the nonusers. [Conclusion]The users of the day care center were frailer than nonusers, especially with regard to independence in instrumental activities of daily living, physical strength, cognitive function, and mood. Health care workers should use the Kihon Checklist to verify frequently the condition of elderly patients to prevent worsening of frailty.

Aim To examine whether arterial stiffness, measured by the cardio-ankle vascular index (CAVI), is associated with skeletal muscle mass index (SMI) in Japanese community-dwelling older adults. Methods Data were collected from 175 participants through questionnaires and specific tests; the data included demographic, lifestyle and health characteristics, body mass index (BMI), and body composition features determined by the bioelectrical impedance analysis, ankle-brachial index, the Mini-Nutritional Assessment, handgrip strength (GS), walking speed and shuttle walking tests (SW), and arterial stiffness determined by the CAVI. Absolute SMI was dichotomized according to the first quintile, which determined low (n = 35) and normal (n = 140) SMI. Results Participants with low SMI were older (P = 0.01), had more polypharmacy (P = 0.01), a lower BMI (P

Background/Purpose: Aging populations are a global public health concern. The risk of falls increases with age, so fall prevention is becoming an important health issue. However, few studies have focused on cross-cultural analyses of falls. Therefore, we aimed to compare the incidence of falls and compare anthropometric measures and physical function between active Japanese and Brazilian older adults. Materials and methods: We measured the incidence of falls (investigated by self-reported questionnaire), body mass index (BMI), waist circumference (WC), grip strength (GS), one-legged stance (BALANCE), frequency of physical activity (PA), medication use (MU), and hospitalization history in 114 physically active community-dwelling adults 65 years of age and older in Japan (73.9 � 4.0 years, n ¼ 40) and Brazil (70.7 � 4.5 years, n ¼ 74). Results: The Japanese elderly were older (p < 0.01), but had a better BALANCE score (p < 0.05) than the Brazilian elderly. Nevertheless, Brazilian elderly showed higher engagement in PA and had higher BMI and WC (p < 0.01). Despite the lack of a difference in the incidence of falls between the two cohorts, Japanese elderly who fell had decreased GS compared to Japanese elderly who did not fall [odds ratio (OR): 0.83, 95% confidence interval (CI) 0.72e0.97, p < 0.05]. In Brazil, those who fell had larger WC than those who did not fall (OR: 1.07, 95% CI 1.01 e 1.13, p < 0.01). Conclusion: Our results indicate that physical function (i.e., grip strength) is a more important predictor of falls in Japanese elderly. However, increasing waist size is a predictor of falls in Brazilian elderly. These findings suggest that risk factors for falls are multifactorial and vary according to setting.
