The aims of this study were to characterize the spontaneous physical activity of children during school recess, and to estimate variation in physical activity associated with gender and age. A MTI actigraph (Model 7164) was used with a sample of 140 boys and 131 girls, 6 to 10 years of age. MTI counts were converted to METs using a regression equation developed for children. The number and average duration of periods of activity by intensity were calculated for each child during a 30 minute recess: rest or mild physical activity (≤ 2.9 METs), moderate physical activity (3.0-5.9 METs,), vigorous physical activity (6.0-8.9 METs) and very vigorous physical activity (≥ 9.0 METs). Boys and girls spent about 50% of the recess in physical activity. Physical activity was characteristically done in very short bursts with intervals of rest or mild physical activity. The number of episodes of physical activity of all intensity levels was lower in older children while the inverse occurred at rest or mild physical activity. Boys engaged in higher intensity activity than girls and in general spent more recess time in physical activity.

The importance of physical activity in promoting health and well-being of the young adult population is evidenced by several epidemiological studies. The increasing incidence in this population of cardiovascular, metabolic and degenerative diseases and obesity has been linked with an epidemic variable, the sedentary behavior, and commonly dubbed the “disease of the century”. Regular physical activity may contribute to the development of muscle strength, improve the quality of soft tissue and bone mass, and decreased body fat. The early inclusion of regular physical activity and other healthy lifestyles tend to be incorporated throughout life with noticeable gains in health and quality of life in adult life. In this study we assessed the physical activity level (PAL), muscle strength (MS) and body composition (BC) of 84 young adults in higher education with the following, assess physical activity; evaluate different manifestations of muscle strength; assess body composition and analyze the relationship between muscle strength, body composition and physical activity in young adults. We drew up a descriptive, correlational and cross-cutting study. To achieve our objective we collected the following data: a) Physical activity: short version of IPAQ (International Physical Activity Questionnaire). b) Muscle strength: hand grip of both hands with Jamar® c) Key pinch strength with digital dynamometer Baseline Hand Dynamometer; ® d) Maximum isometric strength of the quadriceps in seat 45-degree incline leg press machine linked to a strain gauge Ergo Meter – Globus ; ® f) Body composition: bioelectric impedance on Tanita Ironman Body Composition Monitor and appropriated software g) Height: stadiometer Seca A total of 84 university students were subject to this study...

Abstract Background The aim of this study was to determine the prevalence and correlates of physical activity counseling among physicians and nurses working in primary health care in Brazil. Methods A phone survey was carried out in 2011 with professionals working in primary health care in Brazil. The target sample consisted of 1,600 randomly selected primary care units covering all regions of the country. We successfully interviewed 529 professionals within the sampled units; 182 physicians and 347 nurses. The overall response rate was 49.6%. Multivariable logistic regression was used to estimate correlates of counseling in the whole sample and separately for physicians and nurses. Results The prevalence of regular physical activity counseling for at least six months was 68.9% (95% CI 64.9; 72.8) and was significantly higher among physicians compared to nurses (p < 0.05). Most professionals (93.2%) interviewed were unfamiliar with current physical activity recommendations for health. In the adjusted analysis, physical activity counseling was more frequent among those who report assessing patient’s physical activity (OR = 2.16; 95% CI 1.41; 3.29)...

Background Physical activity in adolescents is associated with short- and long-term health benefits. Physical activity can occur in various domains and is influenced by a complex network of factors. The aims of this study are 1) to describe the physical activity of Brazilian adolescents in physical education classes, during leisure time, and during active commuting and 2) to investigate the socio-demographic and behavioral factors associated with physical activity. Methods The representative sample included 109,104 Brazilian students in the final year of elementary school from 2,842 schools. The weekly frequency and duration of physical activity were assessed. A variety of socio-demographic and behavioral factors were studied. A multiple Poisson regression analysis was used to test for associations between physical activity and the socio-demographic and behavioral variables. Results Most of the students (97.0%) engaged in physical activity in at least one of the domains studied, especially physical education at school (81.7%) and leisure time physical activity (67.5%). However, only 29% of the adolescents reached the recommended level of physical activity. Among the adolescents who reached the minimum recommended time for physical activity...

É reconhecida a importância da atividade física e do estilo de vida na prevenção das doenças cardiovasculares. Programas corporativos de condicionamento físico têm sido utilizados por empresas na tentativa de melhorar a saúde de seus funcionários. O objetivo deste trabalho foi verificar se existe relação entre atividade física e morbidade cardiovascular referidas por gerentes e diretores de uma indústria automobilística. Como objetivos secundários avaliar a associação entre atividade física e outras variáveis relacionadas com o estilo de vida, com a utilização de serviços de saúde, absenteísmo e presenteísmo. Por último, avaliar se a participação em um programa de condicionamento físico supervisionado influenciou a atividade física habitual dessa população. Para tanto, foram estudados 376 indivíduos ativos ou inativos, participantes ou não do programa de condicionamento físico. A atividade física habitual, que foi avaliada por meio do Escore de Baecke, e outras variáveis relacionadas com o estilo de vida, como consumo alimentar de gorduras, frutas e vegetais, hábito de fumar e consumo de bebidas alcoólicas foram levantadas por meio de questionário. O escore de atividade física apresentou associação negativa tanto com relação ao absenteísmo como quanto em relação ao indivíduo que executa trabalho quando doente. Não houve associação estatisticamente significativa com morbidade cardiovascular referida...

RESUMO Introdução: Estudos internacionais mostram que o ambiente está associado com a prática de atividades físicas em adultos e idosos. Todavia, não existem estudos que tenham avaliado essa associação na população idosa do Brasil. Objetivo: Estudar a associação entre as atividades físicas praticadas no lazer e como forma de locomoção com variáveis ambientais em idosos residentes no distrito de Ermelino Matarazzo da Zona Leste do município de São Paulo. Metodologia: 380 idosos (60 anos e mais) participaram do estudo transversal de base domiciliar. Para a avaliação das atividades físicas no lazer e como forma de locomoção foi utilizado o questionário IPAQ (Questionário internacional de atividades físicas) versão longa e para a avaliação das atividades físicas domésticas e no trabalho foi utilizado o questionário do VIGITEL (Vigilância de fatores de risco e proteção para doenças crônicas por inquérito telefônico), além de outras questões inclusas especificamente para o estudo. A avaliação do ambiente foi realizada através de uma escala de percepção adaptada da escala NEWS (Neighborhood Environmental Walkability Scale). Para a análise estatística, seis modelos de análise de regressão logística múltipla foram criados para verificar a associação dos diferentes domínios de atividades físicas (variáveis dependentes: atividades físicas no lazer; atividades físicas de locomoção; caminhada no lazer ou na locomoção) com as variáveis de percepção do ambiente (variáveis independentes)...

INTRODUÇÃO: Atividade física tem mostrado exercer muitos benefícios para saúde materno-fetal. Porém ainda persistem dúvidas em relação à influência da atividade física durante a gestação na prematuridade e baixo peso fetal. Visto que a prematuridade e o baixo peso fetal são conhecidamente as maiores causas para mortalidade e morbidade infantil, torna-se fundamental investigar detalhadamente a relação entre atividade física materna e resultados perinatais.OBJETIVO: Avaliar prospectivamente o nível de atividade física materna, em função do gasto energético em atividade, durante o segundo e terceiro trimestres gestacionais e sua influência sobre resultados perinatais (recém-nascidos pequenos para idade gestacional PIG e prematuridade). MÉTODOS: Foi realizado um estudo epidemiológico, prospectivo, longitudinal e observacional. Em função do cálculo amostral realizado para o estudo a coorte foi composta por 325 gestantes saudáveis que realizavam pré-natal no grupo de baixo risco gestacional do Hospital das Clínicas da Universidade de São Paulo. Foram inclusas apenas gestantes com até 25 semanas de gestação e feto único. Para avaliar a prática de atividade física materna utilizou-se no final do segundo e do terceiro trimestre de gestação o Questionário de Atividade Física na Gestação (PPAQ). Os dados clínicos utilizados para ajustar o modelo de regressão logística...

INTRODUÇÃO: No mundo todo, a alta prevalência de sedentarismo da população trabalhadora é preocupante. A falta de prática de atividade física aumenta os riscos em relação aos prejuízos da qualidade de vida, bem como, a morbidade e mortalidade destes indivíduos. As evidências científicas atuais, apesar de serem fundamentais, são insuficientes para indicar quais ações aplicadas no ambiente corporativo podem contribuir na minimização das condições de risco do sedentarismo. OBJETIVO: Comparar a associação de diferentes práticas de atividade física - atividade física sistematizada (AFS), grupos de treinamento físico programado (TFP) e grupos de aconselhamento à prática de atividade física (GA) sobre o nível de atividade física (NAF) e a percepção da qualidade de vida (QV) de trabalhadores do setor administrativo (ADM) de uma comunidade universitária. MÉTODO: Na fase I foram avaliados 645 sujeitos pertencentes à comunidade de ensino superior (discentes, docentes e trabalhadores ADM) e na fase II foram estratificados da amostra total 165 trabalhadores ADM que foram avaliados e aleatorizados, além do grupo controle (GI), para uma das 3 intervenções: (GII= AFS; GIII=AFS +TFP e GIV= AFS+ GA). As variáveis sociodemográficas...

Purpose: This study examined the effect of the type, level and amount of physical activity in falls and fallrelated injuries. Method: Participants were 506 community-dwelling adults aged >50 years (390 women: 67.7 ± 6.8 years and 116 men: 69.6 ± 6.6 years). Falls, fall-related injuries (slight and severe), and physical activity (type, level and energy expenditure) were evaluated by questionnaires. Confounders included comorbidities, fear of falling, environmental hazards and physical fitness. Results: After adjustment for confounders, logistic analysis revealed that the likelihood of falling decreased by 2% for each 100 metabolic expenditure (MET-min/week) of total physical activity and increased by 5% for each 100 MET-min/week of vigorous-intensity physical activity; total physical activity >1125 MET-min/week and vigorous physical activity <500 MET-min/week were identified as cut-off values discriminating non-fallers from fallers. Compared to the low physical activity level, increased physical activity levels diminished the likelihood of the occurrence of severe fall-related injuries by 76% (moderate) and 58% (high; p < 0.05) in fallers. Conclusions: Being active, especially sufficiently active, reduces fall-related injuries by decreasing falls and by safeguarding against severe injuries when falls occur. At least 1125 MET-min/week of total physical activity including >500 MET-min/week of vigorous intensity seems to prevent falls and...

The main purpose of our study was to quantify, by using accelerometry, daily physical activity (PA) in adults with visual impairments. Sixty-three adults (34.9% women) who are blind (18-65 years) wore an accelerometer for at least 3 days (minimum of 10 hr per day), including 1 weekend day. Nineteen participants (~30%) reached the recommendation of 30 min per day of PA, when counting every minute of moderate or greater intensity. No one achieved that goal when considering bouts of at least 10 min. No differences were found between genders in PA measures. Chronological age, age of blindness onset, and body mass index were not associated with PA. We conclude that adults who are blind have low levels of PA and are considerably less active compared with the general population. Health promotion strategies should be implemented to increase daily PA for people with visual impairments.

Background: Physical activity is a health-enhancing behavior, but few adolescents achieve the recommended levels of moderate-to-vigorous physical activity. Understanding how adolescents use different built environment spaces for physical activity and activity varies by location could help in designing effective interventions to promote moderate-to-vigorous physical activity. The objective of this study was to describe the locations where adolescents engage in physical activity and compare traditional intensity-based measures with continuous activity when describing built environment use patterns among adolescents. Methods: Eighty adolescents aged 11–14 years recruited from community health and recreation centers. Adolescents wore accelerometers (Actigraph GT3X) and global positioning system receivers (QStarz BT-Q1000XT) for two separate weeks to record their physical activity levels and locations. Accelerometer data provided a continuous measure of physical activity and intensity-based measures (sedentary time, moderate-to-vigorous physical activity). Physical activity was mapped by land-use classification (home, school, park, playground, streets & sidewalks, other) using geographic information systems and this location-based activity was assessed for both continuous and intensity-based physical activity derived from mixed-effects models which accounted for repeated measures and clustering effects within person...

non-peer-reviewed; The following literature review describes the benefits of being physically active in childhood and adulthood and also the dangers that accompany inactivity. The benefits of being physically activity as a young person can affect future health and future physical activity levels and this link will be considered as a rationale for promoting physical activity in adolescence. The negative consequences of obesity in childhood and adulthood are also considered. The relationship between childhood and adolescent body composition will be considered and it will be discussed how obesity tracks strongly from adolescence into adulthood meaning the current burden of obesity will affect future health. Like the tracking of physical activity, this link will be considered as a rationale for getting adolescents to be physically active. Irish and international data on physical activity and body composition will also be presented and critically appraised. Measurement of physical activity will also be discussed with a focus on accelerometry. Interventions that are school based will be discussed at the end of the chapter.

peer-reviewed; The primary purpose of this thesis was to determine the associations between low intensity physical activities and indices of health in a particularly inactive population, adolescent females. To achieve this, methodologies which enabled the accurate, reliable and objective measurement of low intensity physical activities were examined and developed. The inclinometer-based activPAL activity monitor was selected as the objective measure of physical activity due to its ability to distinguish between sitting/lying and standing. The validity of the activPAL as a measure of free-living physical activity was investigated, and a count to activity threshold was developed to quantify moderate to vigorous physical activity. Protocols which allowed the examination of both sedentary and physical activity variables were developed and implemented based on activity monitoring best practice. Three sets of cross-sectional data were pooled to examine whether relations existed between low intensity physical activity variables and body composition in Irish adolescent females (n=195). No associations were evident between body composition and sedentary variables. However, negative associations were observed between light intensity physical activity and body composition. Furthermore...

Background Evidence suggests possible synergetic effects of multiple lifestyle behaviors on health risks like obesity and other health outcomes. Therefore it is important to investigate associations between dietary and physical activity behavior, the two most important lifestyle behaviors influencing our energy balance and body composition. The objective of the present study is to describe the relationship between energy, nutrient and food intake and the physical activity level among a large group of European adolescents. Methods The study comprised a total of 2176 adolescents (46.2% male) from ten European cities participating in the HELENA (Healthy Lifestyle in Europe by Nutrition in Adolescence) study. Dietary intake and physical activity were assessed using validated 24-h dietary recalls and self-reported questionnaires respectively. Analyses of covariance (ANCOVA) were used to compare the energy and nutrient intake and the food consumption between groups of adolescents with different physical activity levels (1st to 3rd tertile). Results In both sexes no differences were found in energy intake between the levels of physical activity. The most active males showed a higher intake of polysaccharides, protein, water and vitamin C and a lower intake of saccharides compared to less active males. Females with the highest physical activity level consumed more polysaccharides compared to their least active peers. Male and female adolescents with the highest physical activity levels...

There is currently a dearth of information suitable for the development of evidence-based physical activity and screen time guidelines for children and youth. The overarching purpose of this thesis was to generate findings that could be used to inform public health recommendations for physical activity and screen time. A series of six manuscripts were completed to explore the relationship between physical activity, sedentary behaviour, and health in youth. The first manuscript examined the dose-response relation between objectively measured total and moderate-to-vigorous physical activity with blood pressure and hypertension. Participating in 30 and 60 minutes of moderate-to-vigorous physical activity per day decreased the odds of hypertension in youth by 50% and 63%, respectively. The second manuscript explored the influence of intensity of physical activity and incidental movement on total and trunk adiposity. Moderate-to-vigorous intensity physical activity was found to predict total and trunk adiposity beyond other intensities and incidental movement. The third manuscript sought to determine whether or not physical activity accrued in bouts was more beneficial than total physical activity with relation to being overweight. The inclusion of short and medium-to-long bouts of physical activity decreased the odds of overweight above and beyond total physical activity level. The fourth manuscript included a detailed examination of the relation between physical activity and screen time by considering different forms of physical activity...

Background: Less than half of Canadian youth meet recommended levels of physical activity. This is of concern given the health burden associated with physical inactivity. With the limited success of physical activity interventions, research has begun to focus on how physical and sociocultural environments affect physical activity. Investigation of school and neighbourhood characteristics that facilitate physical activity may identify environmental changes that could increase participation among adolescents. Objectives: The objectives of the two studies comprising the thesis were to examine, among youth in grades 6 through 10: 1) the association between school recreational characteristics and physical activity during free-time and class-time at school, and 2) the effects of perceptions of neighbourhood safety and availability of parks and recreational facilities on physical activity participation outside of school. Methods: Data from the 2006 Canadian Health Behaviour in School-Aged Children Survey (HBSC) were analyzed. Multilevel logistic regression was employed to quantify associations between school and neighbourhood characteristics and physical activity. For the first study, student responses to school-time physical activity scales were dichotomized (≥ 2 vs. <2 hours/week). A cumulative index that considered together policies...

The growing prevalence of childhood and adolescent physical inactivity and obesity are major concerns in Canada. Physical activity promoted within schools should be seen as a way to address these problems, since the majority of children receive public schooling. Research highlighting in-school physical activity helps influence school board and public health officials to create a physically active school environment. Consequently, this study has two objectives. The first is to describe the prevalence of in-school physical activity and four dependent variables in a nationwide sample of 9717 students, using data from the Health Behavior in School–aged Children survey. Dependent variables include life satisfaction, self-rated health, academic performance, and out-of-school physical activity. The second objective examines the association between in-school physical activity levels and these dependent variables, while controlling for potential confounders. Using existing data from the 2005/06 Health Behaviour in School-aged Children Survey, a partial proportional odds model form of ordinal logistic regression was fitted in order to investigate the relationship between in-school physical activity and self-rated health, life satisfaction...

This is the author accepted manuscript. It is currently under an indefinite embargo pending publication by BioMed Central.; Background: Active travel is associated with greater physical activity, but there is a dearth of research examining this relationship over time. We examined the longitudinal associations between change in time spent in active commuting and changes in recreational and total physical activity. Methods: Adult commuters working in Cambridge, United Kingdom completed questionnaires in 2009 and 2012, and a sub-set completed objective physical activity monitoring in 2010 and 2012. Commuting was assessed using a validated seven-day travel to work record. Moderate-to-vigorous physical activity was assessed using the Recent Physical Activity Questionnaire and combined heart rate and movement sensing. We used multivariable multinomial logistic regression models to examine associations between change in time spent in active commuting and tertiles of changes in time spent in recreational and total physical activity. Results: 469 participants (67% female, mean age 44 years) provided valid travel and self-reported physical activity data. 71 participants (54% female, mean age 45 years) provided valid travel and objectively measured physical activity data. A decrease in active commuting was associated with a greater likelihood of a decrease in self-reported total physical activity (relative risk ratio [RRR] 2.1...
