Objectives This study aimed to investigate the energy expenditure of common office-based tasks. The objectives were to: (a) test the classification of tasks as sedentary or light-intensity physical activity and (b) compare the energy expenditure of tasks under two postural conditions (sitting and standing). Background The sedentary nature of office work has been highlighted as a health risk, and strategies to reduce sedentary behavior at work have been developed. However, there is limited evidence to guide the utilization of sit-stand workstations in the workplace for metabolic health benefits...

BACKGROUND: Hearing and vision impairments/problems are associated with increased risk of premature mortality in adulthood. One potential pathway explaining this association is reduced levels of physical activity. Reductions in activity levels due to sensory impairments may commence earlier in life; however, associations between sensory impairments/problems and activity levels in childhood are not well understood. OBJECTIVE: The objective of this study was to examine associations between hearing and vision problems and objectively measured activity levels in a representative sample of British children...

OBJECTIVES: Psychotic patients have poorer health behaviours, including poor diets and sedentary lifestyles increasing their risk for obesity, diabetes, hypertension, and dyslipidaemia, and tend to have a shorter life expectancy as compared to nonpsychiatric populations. Lifestyle intervention programmes that target modifiable risk factors in such patients have produced uneven results. The objective was to evaluate the efficacy of a package of health promotion strategies to improve diet and physical exercise in psychotic patients...

REVIEW
R An, Y Yang, A Hoschke, H Xue, Y Wang
Unsafe residential neighbourhoods are thought to be a risk factor for childhood obesity by discouraging physical activity while encouraging sedentary behaviours, but findings from cross-sectional studies are susceptible to selection bias (e.g. children who are obese disproportionately reside in unsafe neighbourhoods). A literature search was conducted in the Cochrane Library, PubMed, Web of Science and Google Scholar for articles published until January 2017 that used baseline neighbourhood safety levels to predict future weight-related behaviours and body-weight status among children aged 17 years and younger...

Changes in cognitive function induced by physical activity have been proposed as a mechanism for the link between physical activity and academic performance. The aim of this study was to investigate if executive function mediated the prospective relations between indices of physical activity and academic performance in a sample of 10-year-old Norwegian children. The study included 1,129 children participating in the Active Smarter Kids (ASK) trial, followed over 7 months. Structural equation modeling (SEM) with a latent variable of executive function (measuring inhibition, working memory, and cognitive flexibility) was used in the analyses...

BACKGROUND: This study aimed to investigate whether awareness of being monitored by an accelerometer has an effect on physical activity in young people. METHODS: Eighty healthy participants aged 10-18 years were randomized between blinded and nonblinded groups. The blinded participants were informed that we were testing the reliability of a new device for body posture assessment and these participants did not receive any information about physical activity. In contrast, the nonblinded participants were informed that the device was an accelerometer that assessed physical activity levels and patterns...

Although many studies have reported on physical activity (PA) levels using accelerometers, a thorough description of the PA pattern in preschool children during their stay in the preschool, is lacking in the current literature. Furthermore, there remains a lack of understanding of the PA level and pattern in children in the lower end of the PA continuum. The first aim of this study was therefore to describe the PA pattern during a week-long stay in a preschool in all children born in 2011 (either three or four-year-olds) attending public preschools in a municipality in Norway...

INTRODUCTION: Ageing is accompanied by increased risks of chronic disease, declined functioning and increased dependency. Physical activity is critical to retaining health and independence, but the majority of older people are insufficiently physically active to achieve these benefits and have high levels of sedentary (sitting) time. Activity programmes are often offered in retirement villages; however, their uptake is limited. Furthermore, although the physical environment in and around these villages can play an important role in decisions to be physically active, its role is often overlooked by research in these settings...

BACKGROUND: Physical activity (PA) and its health benefits are a continuous point of discussion. Recommendations for children's daily PA vary between guidelines. To better define the amount of PA necessary to prevent overweight and obesity in children, further research is needed. The present study investigates children's compliance to physical activity guidelines (PAGs) and the association between objectively measured PA and body mass index (BMI). METHODS: Participating children were 11 years old (n = 419) and part of the European CHOP trial, which was conducted in Germany, Belgium, Poland, Spain, Italy...
