RESUMO

abstract - This study aimed to identify the prevalence of excess body weight in university students from a representative state in Brazil's southern region and establish associations with the demographic, university environment, and health behavior correlates. A random sample of 5,310 university students answered an online questionnaire with demographic, university environment, and eight health behavior data. Excess body weight was identified using the body mass index (BMI ≥ 25 kg/m2). The data were processed using bivariate analysis and hierarchical multiple regression. The overall prevalence of excess body weight exposure was equivalent to 39.1% [35.7-42.6], with significantly different rates between gender, age, and marital status. Likewise, housing type and study year showed significant associations with excess body weight. Among health behavior indicators, with control of all other variables involved in the model, depressive symptoms (p = 0.031), high stress (p = 0.045), sleep duration < 6 hours/night (p < 0.001), moderate-vigorous physical activity < 150 min/week (p = 0.022) and fruit/vegetable consumption < 5 servings per day (p < 0.001) were independently associated with the outcome. However, tobacco use, binge drinking, and prescription drug misuse did not remain in the adjusted multivariate model. In conclusion, the findings emphasize the importance of proposing and implementing multifaceted preventive intervention actions to prevent health outcomes related to excess body weight, once since significant associations with modifiable factors have been identified.

resumo O objetivo do estudo foi identificar a prevalência do excesso de peso corporal em estudantes universitários de um estado representativo da região sul do Brasil e estabelecer associações com correlatos demográficos, do ambiente universitário e de condutas de saúde. Amostra aleatória de 5310 estudantes universitários respondeu questionário online com dados demográficos, do ambiente universitário e de oito condutas de saúde. O excesso de peso corporal foi identificado mediante o índice de massa corporal (IMC ≥ 25 Kg/m2). Os dados foram tratados através de análise bivariada e regressão múltipla hierarquizada. Prevalência global de exposição ao excesso de peso corporal foi equivalente a 39,1% [35,7-42,6], com taxas significativamente diferentes entre sexo, idade e situação conjugal. Da mesma forma, tipo de habitação e ano de estudo apresentaram associações significativas com o excesso de peso corporal. Entre os indicadores de conduta de saúde, com controle de todas as demais variáveis envolvidas no modelo, sintomas de depressão (p = 0,031), estresse elevado (p = 0,045), duração de sono < 6 horas/noite (p < 0,001), atividade física moderada-vigorosa < 150 min/semana (p = 0,022) e consumo de frutas/hortaliças < 5 porções/dias (p < 0,001) mostraram-se independentemente associados ao desfecho. Contudo, tabagismo, consumo nocivo de álcool e uso indevido de medicamentos controlados não permaneceram no modelo multivariado ajustado. Concluindo, os achados enfatizam a importância de propor e implementar ações de intervenção preventivas multifacetadas a fim de prevenir agravos relacionados ao excesso de peso corporal, uma vez identificada associações significativas com fatores modificáveis.

RESUMO

Os objetivos do estudo foram: (a) identificar e comparar as propriedades psicométricas da versão brasileira do questionário National College Health Assessment II (NCHA IIc) nos formatos impresso e on-line; e (b) verificar a capacidade de concordância entre os dados levantados por ambos os formatos. Ambos os formatos do questionário foram preenchidos por 371 estudantes universitários voluntários. Para identificar as propriedades psicométricas foi calculado coeficiente alfa de Cronbach (consistência interna) e realizada análise fatorial confirmatória e de multigrupo. A concordância entre os modelos foi medida por meio do percentual de concordância, estatística Kappa e coeficiente intraclasse. Os resultados do estudo indicam que a versão brasileira on-line do NCHA IIc forneceu dados de qualidade semelhante ao formato impresso tradicional, com vantagens logísticas e de custos substanciais, possibilitando, desse modo, sua aplicação em estudos futuros com finalidade de analisar condutas de proteção e risco para saúde de estudantes universitários no Brasil.

Current studies (a) identifies and compares the psychometric properties of the Brazilian version of the print and online questionnaire National College Health Assessment II (NCHA IIc); and (b) verifies the concordance capacity between data for the two formats. The two types of formats were filled by 371 higher education students. Psychometric properties were identified by Cronbach alpha coefficient (internal consistency) and confirmatory and multi-group factorial analysis was provided. Concordance between models was measured by concordance percentage, Kappa statistics and intraclass coefficient. Results show that the Brazilian version of NCHA IIc provided quality data similar to tradition print version, with logistic advantages and significant costs. Its application in future studies to analyze health protection and risks of university students in Brazil is recommended.

RESUMO

INTRODUÇÃO: O tiro esportivo desenvolve nos atletas destreza, concentração e equilíbrio. A estabilidade do atirador depende da resistência deste contra perturbações internas e externas que afetem seu equilíbrio. OBJETIVO: Avaliar o controle postural e sistema vestíbulo-oculomotor de atletas atiradores de pistola. MÉTODO: Análise descritiva do tipo transversal. Avaliaram-se oito atletas com idade média de 37 anos (dp ± 8,11), afiliados à Confederação Brasileira de Tiro Esportivo. Utilizou-se prontuário sociodemográfico; estabilometria associada a simulador de tiro e sistema de videonistagmoscopia computadorizada. RESULTADOS: Observou-se em todos os voluntários, dominância motora à direita; metade deles atira com os dois olhos abertos; tempo médio de prática de 14 anos (dp ± 9) e média de treino semanal de 14 horas (dp ± 13). Metade relatou lesão associada ao tiro. Na estabilometria observou-se correlação nas velocidades anteroposterior e mediolateral.À videonistagmoscopia, nenhum atleta apresentou alteração patológica. CONCLUSÃO: O controle postural dos atletas avaliados possui alterações significativas para as velocidades de deslocamento do centro de pressão nas direções anteroposterior e mediolateral. O sistema vestíbulo-oculomotor não mostrou correlação com o controle postural e se apresentou sem alterações funcionais para todos os voluntários.

INTRODUCTION: Shooting sports develop dexterity, concentration and balance in the athletes. The stability of the shooter is dependent on his/her resistance against internal and external disturbance that affects his/her balance. OBJECTIVE: To evaluate the posture control and vestibular-oculomotor system of athletic pistol shooters. METHODS: A cross-sectional descriptive analysis. Eight subjects (mean age of 37 years; SD ± 8.11), affiliated to the Brazilian Shooting Confederation were evaluated. A sociodemographic questionnaire, besides stabilometry associated with the shooting simulator and videonistagmoscopic computerized system were used. RESULTS: All volunteers presented right motor dominance; half shot with both eyes open; average practice time is 14 years (SD ± 9) and weekly training average is of 14 hours (SD ± 13). Half athletes reported injuries associated with shooting. Stabilometric correlation presented correlation in the anteroposterior and mediolateral velocities. None of the athletes presented pathological alteration in the videonistagmoscopic evaluation. CONCLUSION: Posture control of the assessed athletes presents significant changes to the displacement of the center of pressure velocities in the anterior-posterior and medial-lateral directions. The vestibulo-ocular system was not correlated with posture control and functional changes were not observed in any of the volunteers.

RESUMO

A Mobilização Neural é um recurso terapêutico para as diversas disfunções do tecido neural e do sistema musculoesquelético. No entanto, é uma técnica ainda pouco conhecida e explorada pelos profissionais da área da saúde no Brasil. Diante disto resolveu-se realizar este estudo com intuito de avaliar sua eficiência na hérnia de disco lombar em relação à fisioterapia convencional. Participaram do estudo 30 indivíduos com hérnia de disco lombar unilateral,voluntários, selecionados por conveniência, independente de sexo,idade, tempo de acometimento, etnia e atividade profissional, desde que preenchessem os critérios de inclusão e exclusão, que foram divididos em grupo experimental (EXP) e controle (CONT), com15 participantes em cada, que receberam tratamentos distintos. O grupo CONT recebeu tratamento fisioterápico convencional enquanto o grupo EXP foi submetido ao tratamento de Mobilização Neural. A duração do programa foi de quatro semanas, com três sessões semanais. Ao se avaliar o efeito terapêutico em relação à dor ea incapacidade funcional, não se observou diferença estatisticamente significativa no grupo controle (CONT) na comparação intra-grupo(pré x pós). Já no grupo experimental (EXP), esta mesma comparação,pré e pós-tratamento, mostrou diferença estatisticamente significativa em relação à dor e a capacidade funcional, pelo teste de Kruskal Wallis (p = 0,0001). Quando se realizou a comparação inter-grupos ( pós-EXP x pós-CONT), encontrou-se um intervalo de confiança (IC) favorável ao grupo EXP (IC: -46,48/-5,79). Os resultados deste estudo evidenciaram resposta terapêutica satisfatória para regressão da sintomatologia dolorosa e incapacidade funcional,utilizando-se a técnica de Mobilização Neural na hérnia de disco lombar, unilateral, póstero-lateral, subaguda em curto período de tempo.

The Neural Mobilization is a therapeutic resource in many neural tissue and musculoskeletal system dysfunctions. Nevertheless, this technique remains underexploited by the health professionals in Brazil. Thirty individuals with unilateral lumbar disc herniation were selected by convenience, regardless of gender, age, duration of symptoms, ethnical group and professional activity, since they satisfy the inclusion and exclusion criteria. This sample was divided into two groups: experimental (EXP) and control (CONT), with15 participants each group, who received different treatments. The group CONT received conventional physical therapy treatment while the EXP group was submitted to the neural mobilization treatment. The individuals were treated for 4 weeks, with 3 weekly sessions. The control group (CONT), after using the conventional physical therapy techniques, did not show a statistically significant difference in comparison to the intragroup (pretreatment x post--treatment). On the other hand, the experimental group (EXP)showed a statistically significant difference in relation to pain and the functional capacity using the Kruskal Wallis test (p = 0.0001).When the results in the pre and post-treatment were compared intragroup post-EXP x post-CONT, the confidence interval (IC)was in favor of group EXP (IC: -46.48/-5.79). The results, in this study, showed a good therapeutic response, with regression of the painful symptomatology and functional incapacity, using Neural Mobilization technique, in individuals with unilateral, posterolateral,subacute lumbar disc herniation, in a short period.

RESUMO

OBJECTIVE: The purpose of this study was to investigate the correlation between body adiposity and postural control in elderly women. INTRODUCTION: Aging and obesity account for a significant portion of healthcare spending. Life expectancy is increasing worldwide, and Rio de Janeiro has the largest proportion of elderly residents of all Brazilian states. METHODS: A total of 45 women underwent bioelectrical impedance analysis, waist circumference measurements, weight and height measurements, and stabilometric tests in eight different stance conditions (opened and closed bases with both eyes opened and closed and right and left tandem and unilateral stances with eyes opened). During unilateral stances, the number of hand or foot contacts was counted. RESULTS: Weight, body mass index, waist circumference, fat percentage, and fat mass showed statistically significant (p,0.05) and positive correlations with the number of contacts made during unilateral stances. The subjects with greater fat mass showed significantly higher anterior-posterior standard deviation and range when their eyes were closed. The sway area was also greater for this group in opened base when their eyes were closed. DISCUSSION: The results relating body adiposity and postural control can be explained by the difficulty of maintaining a greater quantity of body fat mass within the limits of the individual support base, especially while assuming a unilateral stance. CONCLUSION: The subjects with a greater fat mass exhibited poor balance control, indicating that body adiposity level was associated with postural control in the elderly women examined in the present study.

RESUMO

UNLABELLED: Benign Paroxysmal Positional Vertigo (BPPV) is characterized by vertigo, lasting for a few seconds and usually managed by head positioning maneuvers. To educate clinicians concerning the state-of-the art knowledge about its management, the international societies developed guidelines. AIM: the aim of this paper is to discuss, in a practical fashion, the current options available to manage BPPV. STUDY DESIGN: non-systematic review. This study reviews two recent guidelines regarding the evaluation and treatment of BPPV. The first one was published by the American Academy of Otolaryngology Head and Neck surgery (AAO-HNS) and the other by the American Academy of Neurology (AAN). The similarities were presented in different tables. RESULTS: Those guidelines presented differences regarding methods. Only the AAO-HNS guidelines recommend the Dix-Hallpike test for the diagnosis of BPPV. Only canalith repositioning maneuver, Semont maneuver and vestibular rehabilitation had showed some benefit and were recommended as good treatment options. CONCLUSIONS: Both guidelines fulfilled all the aspects required for clinicians to diagnosed and manage BPPV; only the AAO-HNS's guidelines were more comprehensive and of better quality.

A Vertigem Posicional Paroxística Benigna (VPPB) é caracterizada por tontura rotatória com duração de segundos e tratada com manobras cefálicas. Para sistematizar a conduta e conduzir os clínicos no atual conhecimento no seu controle, sociedades internacionais desenvolveram diretrizes. OBJETIVO: Discutir de forma prática e didática o estado da arte da abordagem atualmente disponível para VPPB. MATERIAL E MÉTODOS: Revisão assistemática com análise crítica comparando os resultados de duas recentes diretrizes internacionais a respeito da avaliação e controle da VPPB. Uma pesquisa foi elaborada pela American Academy of Otolaryngology (AAO-HNS) e a outra preparada pela American Academy of Neurology (AAN). Os tópicos em comum foram separados em tabelas comparativas. RESULTADOS: As diretrizes apresentaram diferenças quanto à metodologia. Apenas o artigo da AAO-HNS abordou sobre diagnóstico, recomendando o teste de Dix-Hallpike. Quanto aos tratamentos abordados, apenas a Reposição Canalítica, Manobra de Semont e a Reabilitação Vestibular tiveram estudos suficientes para receber recomendações. CONCLUSÃO: As duas diretrizes apresentaram os respaldos científicos necessários para os profissionais que atuam no diagnóstico e controle da VPPB, porém o resultado do grupo multidisciplinar da AAO-HNS foi mais abrangente e com qualidade superior.

RESUMO

Este artigo analisa o processo de federalização da Escola de Educação Física da Universidade Federal do Rio Grande do Sul sob o olhar dos discentes que se graduaram em 1970 na primeira turma formada sob o regime federal de ensino. Fundamentada no aporte teórico da História Cultural analisamos aspectos relacionados ao envolvimento político dos alunos nesse processo bem como aspectos relacionados a estrutura e funcionamento da Escola como um todo. Para tanto, recorremos a História Oral entrevistando discentes e docentes do período bem como analisamos fontes de diversa natureza tais como documentos, atas de reuniões, livros, reportagens de jornal, fotografia entre outras. Da análise realizada apreendemos que esta turma vivenciou a federalização de modo muito peculiar: por dentro do processo, mas, em certa medida, muito afastada dele

This paper analyzes the process of federalization of the School of Physical Education of the Federal University of Rio Grande do Sul under the eyes of students who graduated in 1970 in the first group formed under the federal system of education. Based on the theoretical support of Cultural History, we reviewed issues related to political involvement of students in this process and aspects of the structure and functioning of the school as a whole. To this end, we resorted to Oral History, interviewing students and teachers of the period, and analyzed sources of various kinds such as documents, minutes of meetings, books, newspaper reports, photographs, and more. Based on the analysis, we noted that this class has experienced federalization in a very peculiar way: within the process, but to some extent, far away from it

RESUMO

O objetivo deste estudo foi a verificação da possibilidade teórica de que a aprendizagem de uma habilidade motora decorra da observação do aprendiz sobre outros praticantes e seja intensificada em função de um protocolo de sintetização de ondas corticais via estimulação cortical. A amostra foi constituída por 15 crianças, de ambos os gêneros, com faixa etária entre 4-5 anos, que foram submetidas a treinamento motor conforme teoria dos neurônios-espelho. Foi realizado eletroencefalograma, em dois momentos da pesquisa (pré e pós-testes) e observada a performance motora dos grupos. Observou-se que, na Fase de Aquisição e Transferência, os grupos obtiveram melhora na performance motora pela diminuição na média de erros absolutos e equilíbrio nas ondas corticais, embora não tenha sido significativa. O estudo da hipótese investigada na abordagem dos neurônios-espelho associada à estimulação cortical demonstrou melhora no desempenho, na agilidade e na capacidade hábil-motriz.(AU)

To verify the theoretical possibility that learning a motor skill may come from the observation of other practitioners and be intensified due to the protocol of synthesis of cortical waves via cortical stimulation was the objective of this study. Fifteen children, both male and female, aged 4-to-5 years old, divided randomly into three groups which were submitted to a motor training according to the mirror-neuron theory. Electroencephalogram was carried out pre and post-training in order to verify the possible alterations in the cortical standard, and the motor performance of the groups was observed. It was observed that in the Acquisition and Transference Phase, the group obtained improvement in the motor performance due to the decrease of absolute mistakes average and balance in the cortical waves. The values obtained were not significant. The hypothesis of mirror-neuron approach associated with cortical stimulation demonstrated increased global performance of the group, improving the development, the agility and the skilled-motor capacity.(AU)
