OBJETIVO: Avaliar associação entre excesso de peso e consumo de feijão em adultos. MÉTODOS: O estudo constou de indivíduos adultos (>18 anos), moradores em Belém (PA), em 2005. A amostragem foi realizada por sorteio de residências com telefone fixo e de um morador adulto de cada casa sorteada. A variável desfecho foi excesso de peso, a variável explanatória consumo de feijão e as variáveis de controle foram idade, escolaridade e situação conjugal, além de atividade física no lazer e hábitos alimentares de risco. A análise dos dados foi feita pelo teste do qui-quadrado e por regressão logística. RESULTADOS: Foram avaliados 2 352 indivíduos (39,8% do sexo masculino). O excesso de peso atingiu mais os homens, 49,3%, do que as mulheres, 34,0% (p<0,001). A prevalência de excesso de peso apresentou associação direta com idade em ambos os sexos e com escolaridade para homens, para as mulheres a associação com a escolaridade foi inversa. A variável referente ao consumo alimentar que melhor se associou com excesso de peso foi o consumo de feijão. Após ajuste para as demais variáveis, o risco de excesso de peso foi cerca de 1,4 vez maior para os homens que consomem feijão menos do que cinco vezes na semana, porém o inverso para as mulheres. CONCLUSÃO: Os resultados indicam a necessidade de estudos mais controlados para melhor entendimento da associação entre consumo de feijão e excesso de peso.

O objetivo do presente estudo foi analisar a associação da prática de caminhada no domínio lazer e no domínio deslocamento com a percepção do ambiente em adultos residentes no município de Rio Claro - SP. Foi realizado um estudo transversal de base domiciliar com amostra composta por 470 adultos (45,7±17,8 anos). Os sujeitos responderam o Questionário Internacional de Atividades Físicas (versão longa) e uma versão adaptada da Escala de Mobilidade Ativa no Ambiente Comunitário, que foi utilizada para investigar a percepção do ambiente construído e social. Para análise dos dados foi realizada uma regressão logística, sendo considerado como desfecho, caminhar ≥10minutos/semana no domínio lazer e no deslocamento. A prevalência de sujeitos que realizavam caminhada no lazer foi de 20,6% e 58,9% para a caminhada no deslocamento. A prevalência de caminhada no deslocamento entre as mulheres foi maior quando comparado com os homens (66,3% e 50,0%, respectivamente) e menor no domínio lazer (19,8% e 21,7%, respectivamente). A caminhada como forma de deslocamento foi associada com sexo feminino, classe econômica mais baixas (C, D e E) e percepção da disponibilidade da presença de faixa de pedestre. Para a caminhada no domínio lazer as variáveis pessoais e do ambiente que se associaram foram: idade (60 anos ou mais), classe econômica (B2, C, D e E), convite de amigos e/ou vizinhos para a prática. Os resultados apresentados demonstram que há uma associação entre a percepção do ambiente e a prática de caminhada no lazer e no deslocamento.

O objetivo deste artigo é verificar a prevalência de desnutrição em adolescentes de duas cidades brasileiras e analisar possíveis associações com a prática de atividades físicas durante horários de lazer. Participaram do estudo 2782 adolescentes de 10 a 17 anos, de escolas da rede pública e privada de uma cidade do sudeste e uma da região sul. O peso e a estatura foram avaliados por balança digital e estadiômetro, respectivamente. A prática de atividade física considerou as variáveis: prática de esportes; andar (tratada como caminhada); andar de bicicleta e assistir televisão. O teste qui-quadrado e a regressão de Poisson foram empregados. A prevalência de desnutrição foi de 13,0%, sendo maior no sexo feminino (14,5%) quando comparado ao masculino (11,9%) [p = 0,047]. A prática esportiva foi associada com menor ocorrência do desfecho (p = 0,001). Foi significativamente menor a prevalência de desnutrição entre aqueles que mantinham frequência moderada de caminhadas em comparação àqueles que apresentavam baixa frequência dessa prática. A prevalência de desnutrição no presente estudo pode ser considerada elevada. Além disso, a condição nutricional inadequada nos adolescentes aparentemente está associada a comportamentos de risco à saúde, caso da prática insuficiente de atividade física durante horários de lazer.

The goal of this research was to characterize written stories, produced by students, without complaint of language development (oral and written), from pictographic support. In a specific way, it has been searched, in those stories, elements that could grant coherence, applying that performance with the participants’ profile variables. It was characterized as a descriptive-exploratory study, held at a rural municipal school in the State of Parana. Twenty-one (21) students of both genders and ages between seven and nine years old have participated in this study. Data collection consisted of two narratives requests: one oral, after being released, to the child, four pictures placed in sequence to form a story, and one written. This writing production had been taken for the analysis. The results have indicated that most children (71.42%) managed to produce coherent stories, seventeen (80%) in story 1 and thirteen (61%) in story 2. As to the relation of that coherence with the students’ profile in story 1, there has been no statistically significant association, for none of the analyzed variables (gender, age and education), whereas there has been a statistically significant association with gender in story 2 (p-value 0.027). It is considered that the use of the pictographic support in developing stories have been confirmed as a facilitating strategy for its construction, for it has enabled the production of coherent narratives.

Introduction: The pulmonary rehabilitation (PR) is composed of aerobic and resisted exercises that improve the functional capacity to the exercise, life quality and decrease respiratory symptoms in subjects with chronic pulmonary disease. Objective: Assess the effects of a combined PR program in the cardiorespiratory function and peripheral muscle strength in subjects with chronic pulmonary disease. Method: Patients with chronic pulmonary disease were submitted to the PR program, which was developed on 24 sessions of 60 minutes (three times per week). The program was composed of aerobic exercises (two times per week) and resisted exercises (once a week). Before and after the PR the patients were submitted to manovacuometry in order to measure the maximum inspiratory pressure (MIP) and the maximum expiratory pressure (MEP), ventilometry, peek expiratory flow (PEF), six minute walking test (6MWT) and one maximum repetition (1RM). The data are presented in absolute frequency, percentage and mean±standard deviation. The t Student test was used to compare data before and after the PR and the ANOVA test to compare before, after and predicted distances in the 6MWT (p<0.05). Results: Seven patients were part of this study, 85.70% of women, 71.40% with pulmonary emphysema diagnosis. The mean age was 69.43±5.59 years old, the height was 1.61±0.07 m, the mean weight was 66.20±8.40 kg and the body mass index mean was 25.50±2.48 kg/m². From the variables assessed, the MEP increased from 79.71±13.69 to 84.42±12.83 cmH2O (p=0,03), the PEF increase from 255.71±66.3 to 320.00±93.63 l/min (p=0,03) and the distance in the 6MWT from 415.28±47.90 to 483,79±79,77 m (p=0,02). The load in the 1RM test in the reverse peck deck exercise (before - - 17.10±8.10kg; after – 210.40±9.00kg), knee in leg extension machine (before – 17.10±9.50kg; after – 26.40±13.10kg) and hip extensors (right before – 48.60±22.10kg; after – 62.90±19.30kg; and left before – 46.40±20.10kg; after – 62.10±18.20kg) increased significantly (p<0,05). Conclusion: After the PR program there was improvement in the expiratory muscular strength, in the lower limbs strength and in the functional capacity. Besides that, there was a reduction in the airflow obstruction of the subjects with chronic pulmonary disease.

Introduction: Given the repercussion of the important role of physical activity in the prevention of sickness and non-communicable diseases / loss, many works have been done in order to understand the association of sociodemographic characteristics with sedentarism. The elements which influence the physical activity practice are countless. Besides the intrapersonal element, environment elements (social environment, cultural environment, public politics, information environment, natural environment etc.) are also important in the life style. Yet, the way that the person understands the environment can be considered in the planning of the strategies to change the sedentary behavior. Objective: Verify the association of the environment perception with the practice of physical activity (FA) at leisure time in adults living in Rio Claro – SP. Methodology: The sample consists of 470 adults, all residente in rio Claro-SP, aged ≥ 18 years old. The chosen participants answered to the questionnaires: Neighborhood Environmental Walkability Scale (NEWS), International Physical Activity (IPAQ) and to a specific questionnaire with personal data (age, sex, educational level, economical level, weight, height and marital status). The analysis of the connection between the variables was done through the Logistic Regression with Confidence Interval of 95%, using the software SPSS 17.0. Those who reached the recommendation of 10 minutes or more of physical activity in leisure time for week were classified as active, and those who did not reach the recommendation were classified as underactive. Results: The proportion of subjects who practiced physical activity in leisure time was 38,7%, and the male subjects, as well as those classified as better social level showed higher chances to practice at least 10 minutes weekly of physical activity during leisure. Still, walking the dog, soccer fields and gardens near the house (less than 10 walking minutes), were...

Mouse embryo production by superstimulation is a multifactorial process. To minimize the number of sacrificed animals and to maximize the results of the superstimulatory treatment, it should be possible to predict the risk of do not get embryos from such a treated animal. This work aimed to evaluate if the variables - hormone concentration and the timing of its administration, the copulatory plug presence and individual male used to mating – could be predictive factors on the mouse embryo production. Females were distributed in four groups (cross-over design) related to scheduled superstimulation treatment (1300h or 1700h) and eCG/hCG administered concentration (5 or 10IU). After the hCG treatment, females were put to mate. On the next morning it was verified the presence of a copulatory plug (D0.5). Embryo recovery was performed from D2.5 to D4.5 by flushing the oviducts and uterine horns. Total structures recovered (TSR) and the viable embryos (VE) were classified by its morphology. Viability rate (VR) was calculated with VE in relation to TSR (x100). Group comparison was analyzed with 5% of significance. There were no significant differences among groups, even when only main effects were analyzed (hormone concentration and timing of its administration). There was significant difference in VR from animals with or without plug and from the worst and best males used. It was concluded that neither the hormone concentration nor timing of its administration - or their association – was significant as predictive factors for the embryo production. However, the plug presence was related to higher VR.
