Childhood obesity is a public health concern with significant health and economic impacts. We conducted a prospective experimental study in 4 classrooms in central Texas to determine the effect of desks that encourage standing rather than sitting on caloric expenditure in children. Students were monitored with calorie expenditure-measuring arm-bands worn(More)
OBJECTIVE This study sought to investigate the prevalence of laparoscopic surgeon injury/illness symptoms and evaluate associations between symptoms and operating room ergonomics. BACKGROUND Although laparoscopic procedures significantly benefit patients in terms of decreased recovery times and improved outcomes, they contribute to mental fatigue and(More)
Due to the increasing prevalence of childhood obesity, the association between classroom furniture and energy expenditure as well as physical activity was examined using a standing-desk intervention in three central-Texas elementary schools. Of the 480 students in the 24 classrooms randomly assigned to either a seated or stand-biased desk equipped(More)
BACKGROUND Schools have been suggested as a viable avenue to combat childhood obesity. School administrators are sometimes faced with the conflicting demands of improving the health of their students and maintaining academic performance. Dynamic furniture such as stand-biased desks may be one way to address both academic and health demands placed on schools(More)
Childhood obesity has grown into a national epidemic since the 1980s. Many school-based intervention efforts that target childhood obesity involve curriculum and programming that demands instructional time, which disincentivizes school participation. Stand-biased classrooms are an environmental intervention that promotes standing rather than sitting by(More)
OBJECTIVES To measure changes in body mass index (BMI) percentiles among third- and fourth-grade students in stand-biased classrooms and traditional seated classrooms in 3 Texas elementary schools. METHODS Research staff recorded the height and weight of 380 students in 24 classrooms across the 3 schools at the beginning (2011-2012) and end (2012-2013) of(More)
BACKGROUND While much is known about the benefits of physical activity (PA) and the consequence of sedentary behaviors relative to body mass index (BMI), little is known about the homogeneity of these effects across individuals. The goal of this study was to determine if PA and sedentary behaviors have the same effect on individuals of all BMI(More)
Standing desks have proven to be effective and viable solutions to combat sedentary behavior among children during the school day in studies around the world. However, little is known regarding the potential of such interventions on cognitive outcomes in children over time. The purpose of this pilot study was to determine the neurocognitive benefits, i.e.,(More)
BACKGROUND Recent evidence of obesity-related changes in the prefrontal cortex during cognitive and seated motor activities has surfaced; however, the impact of obesity on neural activity during ambulation remains unclear. The purpose of this study was to determine obesity-specific neural cost of simple and complex ambulation in older adults. METHODS(More)
