The Role Of Environmental Context In Supporting Children’S 24- Hour Movement Behaviors; A Positive Deviance Perspective, Roddrick Dugger

Theses and Dissertations

Background: During summer, children display less favorable movement behaviors than the school year. To investigate the role of environmental context in supporting children’s ability to meet the 24-hour Movement Guidelines (i.e., Moderate-to-Vigorous Physical Activity: ≥ 60 minutes, Sleep duration: 9-11 hours, Screen Time: ≤ 2 hours), this dissertation had three primary aims: 1) Utilize the Positive Deviance Framework to identify unique practices and resources that enabled children to meet guidelines, 2) Examine potential associations between the neighborhood built and social environment with movement behaviors by household poverty experience, and 3) Identify specific features of the family and home environment that …

Relationships Among Sleep, Physical Activity, And Weight Status In Children And Adolescents, Agnes Bucko

Theses and Dissertations

Sleep and physical activity are both associated with multiple behavioral and metabolic health outcomes, and both behaviors have been linked to the development of weight status. Recent estimates suggest that many children are not meeting sleep recommendations or participating in adequate levels of physical activity, which may be related to the high prevalence of childhood overweight and obesity. Much of the research assessing these relationships has focused on adults and older children, and has relied on parent- or child-reported, cross-sectional research in predominantly White samples. Little work has focused on these relationships in very young children. Although more research has …

The Relationship Of Structured Environments With Children’S Body Composition And Obesogenic Behaviors, Ethan T. Hunt

Theses and Dissertations

Recent nationally representative data show among children and adolescents aged 2 to 19 years, the prevalence of obesity is 17.0% (95CI= 15.5%-18.6%). Further, rates of obesity are disproportionately high among minoritized youth. The prevalence of children and adolescents with obesity is lower among White children compared to Black children (14.7% vs. 19.5%) or Hispanic children (14.7% vs. 21.9%). Disparities by socioeconomic status exist as well. Prevalence of children with obesity from households with an income that is >350% of the federal poverty threshold (after accounting for household size) is significantly less compared to children from households with an income that …

Feasibility And Efficacy Of A Recess-Based Combined Fitness Intervention On Cognition And Academic Performance In Elementary School Children, Christine St Laurent

Doctoral Dissertations

Youth physical activity and fitness have been reported to influence cognition and academic related outcomes. Despite the potential benefits of muscular fitness, few intervention studies have examined the impact of an intervention that has incorporated both cardiorespiratory and muscular fitness training on cognition and academic performance in children. Previous studies have mainly been implemented either during the school day or immediately after-school. Although recess may be an ideal time to promote physical activity because it does not compete with other academic demands, it has been an understudied setting. Therefore, the purpose of this dissertation project was to examine the feasibility, …

Differences In Running Mechanics And Tibial Plateau Dimensions Between Overweight/Obese And Healthy Weight Children, Claire Sylvestre

Electronic Theses and Dissertations

INTRODUCTION: Overweight and obese (OW/OB) children display increased knee joint loading during running, which may lead to excessive frontal plane motion and moments at the knee joints. The relationship between tibial plateau dimensions and knee vertical loading may explain the loading related injuries OW/OB children experience.
PURPOSE: Compare knee mechanics during running and tibial plateau dimensions between healthy weight (HW) and OW/OB children.
METHODS: Ten HW children and ten OW/OB children aged 9-12 participated in the study. Kinematic and kinetic data were captured as participants ran across a force platform at 3.5m/s. Tibial plateau area and density were collected by …

Children’S Obesogenic Behaviors During Summer Versus School, Keith Brazendale

Theses and Dissertations

Emerging evidence shows children gain 3-5 times the amount of weight and lose cardiorespiratory fitness (CRF) during summer compared to the 9-months of the school year. Notably, this trend is more pronounced in children who are already overweight or obese going into summer and/or from low-income ethnic minority households. There is little evidence to investigating the underlying mechanisms driving the pronounced occurrence of these negative health outcomes during summer.

The purpose of this dissertation as a whole was to investigate children’s obesogenic behaviors (physical activity, sedentary/ screen time, sleep, and diet) during summer versus school, and compare any differences in …

Feasibility Of A Combined Physical Activity And Sleep Education Intervention For Girls Living In A Low Socioeconomic Status Urban Community, Cory J. Greever

Doctoral Dissertations

Declining sleep duration and poor sleep quality is a public health epidemic disproportionately effecting elementary age girls living in low socioeconomic status urban communities. The Girls Dancing and Sleeping for Health (Girls DASH) program was designed to test the feasibility, acceptability, and efficacy of a combined physical activity and sleep education program in this population. In combination with baseline data from a previously conducted intervention in elementary age urban girls living in a low SES community in Springfield, MA, results from a cross-sectional analysis indicated that greater screen time was positively associated with parental reports of child’s sleep quality. Additionally, …

The Influence Of Prior Motor Actions On Motor Planning In Children With Autism Spectrum Disorder, Daisha Lynn Cummins

Undergraduate Honors Capstone Projects

Studies have found children with Autism Spectrum Disorder (ASD) have a rigidity of motor plans and difficulties planning and executing movements. Children with ASD also exhibit repetitive behaviors such as nail biting and rocking back and forth. When planning for movements, repetitive behaviors might manifest as difficulty in formulating new or switching between different motor plans. In typically developing individuals, actions are often influence by recently performed motor actions. We sought to determine if this influence was stronger in children with ASD.

A rotation motor task was created to evaluate the rigidity of motor planning of five children with ASD …

Rep As A Predictor Of Weight Categories Determined By Anthropometric Measurements, Nicholas Mendola

Williams Honors College, Honors Research Projects

Obesity has become one of the leading public health issues in the world today. An aspect of this issue that must be addressed in order for it to not persist as a problem in the future is the issue of childhood obesity. One of the most common screening methods to determine if a child is classified as overweight or obese is to utilize anthropometric measurements like body mass index, and waist-to-height ratios. Past studies have shown that children who are categorized as overweight or obese can struggle with physical activity and typically have lower fitness levels as their anthropometric measurements …

An Exploratory Examination Of Families Engaged In An Adventure Running Kids Program, Heather Isnor

Theses and Dissertations (Comprehensive)

Academics and practitioners have only just begun to delve into the health benefits of outdoor activities in the last few years. In general, the forested settings of these activities have been documented to decrease stress levels, increase recovery rates from disease, and lessen the symptoms of mental illnesses (Kuo & Faber Taylor, 2004). It is believed that the natural environment acts as a setting where humans can engage in physical activity, aesthetic experiences, and social interactions that, in turn, release stress and lead to improved well-being (Bird, 2012). Currently, however, children are experiencing limited exposure to nature and which has …

An Application Of Acceptance And Commitment Therapy As It Relates To Children, Laura Anne Wright

Undergraduate Honors Capstone Projects

This paper expounds upon a modem therapy which has emerged as an effective, albeit less conventional, mode for the treatment of people with Obsessive-compulsive Disorder (OCD). Acceptance and Commitment Therapy, or ACT, is a therapy based on the premise that an effective way of coping with unwanted cognitions, such as those present in OCD, is for one to focus on life ideals and values. This approach contrasts with the conventional method of remedying the symptoms of a mental disorder such as OCD before pursuing life goals. Acceptance and Commitment Therapy has several dimensions which will be discussed.

Cardiorespiratory Responses In Healthy-Weight And Obese Women And Children, Elizabeth Ann Easley

Theses and Dissertations--Kinesiology and Health Promotion

A criterion method to evaluate cardiorespiratory health is measuring peak oxygen consumption (VO₂ peak) from a maximal graded exercise test (GXT). While VO₂ peak is a valuable measure, heart rate recovery (HRRec) and endothelial function (EF) also describe cardiorespiratory health and fitness. The purpose of this study was to investigate whether differences exist in VO₂ peak, HRRec, and EF between healthy-weight (HW) and obese (OB) women and children and to determine if there were significant correlations among these variables. A total of 60 women and children participated in this study. Anthropometric, body composition, resting heart rate and …

Early Child Care And Adiposity At Kindergarten Entry, Jessica D. Mackle

Electronic Thesis and Dissertation Repository

The association between pre-school child care participation and markers of adiposity at kindergarten entry was examined using parent reported previous child care exposure and directly measured body mass index (BMI) and waist circumference (WC) of kindergarten children (N=201; boys=106, girls=95). It was hypothesized that kindergarten children with previous exposure to full-time non-parent child care (FNPC; >20h/week) would have increased risk of overweight/obesity (BMI≥ 85^th percentile) and high central adiposity (WC ≥80^th percentile) compared to parent care (PC). The data suggest that there was no significant relationship between FNPC (n=112) and risk of overweight/obesity (OR=1.17, …

Effects Of Environment On Children's Motor Scores, Eligibility Status, And Administration Times, Derrick Mittelstadt, Abigail Parker, Kirsten Pickett, Heather Temkin

UNLV Theses, Dissertations, Professional Papers, and Capstones

Best practices for assessing developmental skills in young children focus on naturalistic observation in everyday settings, but the effects of environment on test scores, eligibility status and administration time have not been explored. The Peabody Developmental Motor Scales-Second Edition (PDMS-2) was administered to 34 children aged 18 to 59 months in natural and pull-out settings. PDMS-2 total, gross, and fine motor quotient (TMQ, GMQ, and FMQ) scores were significantly lower in the natural environment (p’s≤.014). Based on our results, more children would qualify for services when tested in natural environments using TMQ and GMQ scores. It also took significantly longer …

The Effect Of A Physical Education Games Unit On Children’S Participation In Neighborhood Physical Activity, Beth Erin Eddy

University of Kentucky Master's Theses

Many strategies to increase children’s physical activity have been studied, noted and implemented. It is important that physical educators realize their role in increasing physical activity both in school and outside of school. In order to promote physical activity outside of school it is important to understand what types of physical activities in which children enjoy participating. This study manipulated specific games taught in physical education classes and then explored how many and what types of these activities were continued in out-of-school free play at home in the children’s neighborhood. The students’ activities increased after the intervention, especially the activities …
