Accelerometer-Determined Physical Behavior Metrics And Their Associations With Sarcopenia Among Oldest-Old Adults, Eric M. Eberl

Masters Theses

INTRODUCTION: Sarcopenia is a loss of muscle function and muscle mass which frequently occurs among the oldest-old adult population (aged 85+ years). The analysis of accelerometer-determined physical behavior volumes and patterns of oldest-old adults might provide novel insights into the associations with sarcopenia and its components. METHODS: A total of 145 participants in the primary sample and 87 participants in the subsample with a mean age of 88.2 (2.5) years from the Health, Aging, and Body Composition study cohort provided cross-sectional data of handgrip strength, appendicular lean mass, gait speed, and accelerometry. Probable, confirmed, and severe sarcopenia were assessed based …

Associations Between Physical Activity And Weight Status With Grade-School Performance, Taylor Panfil

Theses and Dissertations

Physical activity and weight control are predictive of childhood health, but more recent research suggests they may also be associated with academic success.

PURPOSE: To explore the relationships between physical activity, weight status, and academic performance in children.

METHODS: 614 third-to-fifth grade children (53.9% female, age 9.6 ± 0.9 years) from two Midwestern communities participated. Physical activity was assessed using a Digiwalker 200-SW pedometer worn for seven consecutive days. Teachers provided an estimate of general academic performance, and children were categorized into three performance groups (high, moderate, low). School behavior (attentiveness, staying on task, interruptive behavior) was assessed by the …

The Role Of Sleep Timing On Diet Quality And Physical Activity Among College-Aged Women Participating In The University Of Massachusetts Vitamin D Status Study, Deniz Azarmanesh

Masters Theses

Overweight and obesity are risk factors for various chronic diseases. Sleep has been associated with overweight and obesity. One potential mechanism by which sleep may lead to overweight and obesity is through positive energy balance (i.e. energy intake exceeding expenditure). There are few studies examining the impact of sleep timing (onset and wake time) on diet and exercise. In a cross sectional study, we examined associations between sleep timing and diet quality, and in separate models, between sleep timing and meeting the 2008 Physical Activity Guidelines for Americans among the participants of the UMass Vitamin D Status Study. A total …

Multilevel Analysis Of Physical Activity Among Us Adults Across Us Census Regions: The Role Of Environmental Contexts, Sariyamon Tiraphat

Health Services Research Dissertations

This study uses nationally representative data to explain the variation in physical activity among U.S. adults across four geographic regions of Northeast, Midwest, South, and West. The purpose of the study is to investigate whether environmental conditions inclusive of natural amenity, built environment, urbanization, crime, and social economic neighborhood are associated with physical activity and whether these associations are modified by geographic region. The study also investigates whether the influences of environmental contexts vary by subgroup and whether they are modified by geographic region. Determining regional factors that influence physical activity is essential to planning appropriate physical activity interventions.
