Identification Of Falls Risk Factors In Community-Dwelling Older Adults: Validation Of The Comprehensive Falls Risk Screening Instrument, Jennifer Marie Fabre
LSU Doctoral Dissertations
Identifying risk factors and those at risk for falls is necessary. The first purpose of the dissertation was to validate the Comprehensive Falls Risk Screening Instrument (CFRSI) that weights falls risk factors and includes the subscale scores of history, physical, vision, medication, and environment, and a total falls risk score. The CFRSI total falls risk score was compared to subscale scores, physical activity, physical function, health-related quality of life (HRQL), and history of falls (Study 1). The second purpose of the dissertation was to determine associations between the CFRSI total falls risk score, race, education, and income (Study 2). Data …

A Descriptive Study Of The Diet And Physical Activity Practices Of Overweight And Obese College Students Enrolled In A Weight Loss Program, Laura Brooke Walters
University of Kentucky Master's Theses
The effect of weight gain on college students may lead to physical and emotional problems that could continue into adulthood. Identifying behavioral, demographic, and psychological factors that impact college student’s weight status could aid in developing programs to help reduce weight and prevent weight gain in overweight and obese college students. This study evaluated the dietary habits, physical activity, and psychosocial characteristics of college students entering a university-sponsored weight loss program. Results suggest that the majority of participants have experienced weight gain in the past year and none have experienced weight loss. The student’s diets tended to include less than …

Methods. A randomized controlled study design assigned 348 individuals to the intervention or control group with measurements taken at baseline, 6 weeks, and 6 months of body weight, physical activity, and serum CRP levels. Participants attended an intensive 40-hour educational course delivered over a four-week period.
Results. At baseline, CRP was negatively associated with total steps/week, and positively associated with weight, BMI, percent fat, and saturated fat …
Emotional Health And Weight Gain: A Prospective Study Of Middle-Aged Women, Ann Bahr
Emotional Health And Weight Gain: A Prospective Study Of Middle-Aged Women, Ann Bahr
Theses and Dissertations
The objective of this study was to investigate the extent to which risk of gaining weight or body fat is affected by emotional health in women. A secondary objective was to determine the influence of age, baseline weight and body fat, physical activity (PA), energy intake, and changes in PA and energy intake, on the relationship between emotional health and gains in weight and body fat. The study was a prospective cohort investigation over 20 months of 256 healthy, non-obese females (age: 35-45 y, BMI < 30 kg/m2). All subjects were assessed for several variables using objective measurements at baseline and again at 20 months. Emotional health was assessed using the General Well-Being Schedule. Body fat percentage was indexed using the Bod Pod. PA was measured objectively using MTI (CSA) accelerometers, and energy intake was measured using weighed, 7-day food records. The results of the study demonstrated that risk of gains in weight and body fat were no greater in depressed women compared to their counterparts. However, 171 (66.8%) subjects demonstrated less than positive (LTP) emotional health at baseline, and 37.4% of these subjects gained weight during the 20-month study. Conversely, 85 (33.2%) subjects had positive emotional health at baseline, but only 23.5% gained weight over the investigational period. With no variables controlled, women with LTP emotional health had 59% greater risk of weight gain over the study period than women with positive emotional health (RR 1.59, 95% CI = 1.04-2.44). Women with LTP emotional health were at no greater risk of gains in body fat percentage than women with positive emotional health (RR 0.96, 95% CI = 0.70-1.33). After adjusting for each potential confounder individually, risk of gaining weight or body fat did not change. However, after adjusting for all of the potential confounders simultaneously, risk of weight gain was weakened (RR 1.43, 95% CI = 0.93-2.21). These results seem to demonstrate that middle-aged women with LTP emotional health may be at increased risk of gaining weight compared to women with positive emotional health.

College Student's Motivation For Physical Activity, Lori Lynn Delong
LSU Doctoral Dissertations
The purpose of this study was to examine college students' motivations to be physically active by merging the perspectives of self-determination theory and the transtheoretical model. The secondary purpose was to examine the effects of a required physical activity course on college students' levels of physical activity. The premise is that both the theory and model can be used to help predict physical activity outcomes. Participants were 277 male and female students at a small private college. Motivation, self-determination, stage of change, self-efficacy, decisional balance, and leisure time activity levels were assessed using an online survey. Results revealed that activity …
Physical Activity Behavior Of University Students: An Ecological Approach, Lisa Gaye Johnson
Physical Activity Behavior Of University Students: An Ecological Approach, Lisa Gaye Johnson
LSU Doctoral Dissertations
Despite the health benefits associated with active lifestyles, a majority of adults do not engage in sufficient levels of physical activity (PA). Few individual-focused interventions have produced sustained changes in PA behavior. Therefore, public health officials are promoting the use of ecological approaches to examine the multidimensional factors that influence choices about PA and other health behaviors. National statistics are mirrored in college populations, with one-half of students in the US failing to meet current PA recommendations and one-third classified as either overweight or obese. In light of this, increasing PA and obesity prevention have been identified as the top …
Self-Determination In Physical Education: Designing Class Environments To Promote Active Lifestyles, Charity Leigh Bryan
Self-Determination In Physical Education: Designing Class Environments To Promote Active Lifestyles, Charity Leigh Bryan
LSU Doctoral Dissertations
The purpose of this study was to investigate the relationships between self-determination, perceptions of the motivational climate, attitude, perceived ability, engagement in physical activity, and health-related fitness indicators. Two structural models related to engagement/intention to engage in physical activity and health-related fitness were tested. The premise of both models is that perceived competence predicts the outcome variables (engagement or health-related fitness), with self-determination, attitude, and motivational climate predicting perceived competence. Participants were 827 sixth, seventh, and eighth graders. Motivation, perceptions of the climate, attitude, perceived competence, and self-reported physical activity levels were assessed using surveys. Pedometers were used to record …
Health And Lifestyle Profiles Across The Lifespan: Results From The Louisiana Healthy Aging Study, Madlyn Irene Frisard
Health And Lifestyle Profiles Across The Lifespan: Results From The Louisiana Healthy Aging Study, Madlyn Irene Frisard
LSU Doctoral Dissertations
Aging and age related disease affects individuals differently. One possible explanation could be free radical production varies among individuals and this variation determines the aging process and the progression of disease. The purpose of this study was to test whether nonagenarians have a relatively low metabolic rate when compared to younger individuals and whether this low metabolic rate is associated with lower levels of oxidative stress and less incidence of disease. Resting metabolic rate (RMR), markers of oxidative stress to lipids, proteins, and DNA, components of the metabolic syndrome, and physical activity level were measured in 3 groups of individuals …

Variance In Percent Body Fat Between And Within Families As Measured By Dual-Energy X-Ray Absorptiometry, Laurel Anne Kelsey
Theses and Dissertations
Objective: To determine the variance in percent body fat between and within families as measured by dual-energy x-ray absorptiometry (DXA). Methods: Percent body fat (%BF) assessed in 95 females, 120 males (included 54 sets of biological siblings) using DXA. Physical activity questionnaire used to assess current physical activity habits in each participant. Results: Variance in %BF between and within families is similar. Amount of television viewing and levels of physical activity can affect %BF. Discussion: A model such as the one derived in this study can be a useful tool in intervention programs implemented to decrease obesity.
Body Mass Index And Soft Drink Consumption Among Adolescents, Olivia Love Mccord
Body Mass Index And Soft Drink Consumption Among Adolescents, Olivia Love Mccord
Theses and Dissertations
Objective: To determine the relationship between body mass index (BMI) and soft drink consumption among adolescents. It is hypothesized that soft drink consumption contributes to overweight and obesity among adolescents.
Background: Research examining the relationship between body mass index and soft drink consumption is inconsistent. Several studies have found a negative association between total sugar intake and BMI; however, others have found a link between sugar-sweetened drinks and obesity. There are no known studies that have controlled for physical activity.
Data and Methods: Data on approximately 225 adolescents were used. Frequency of soft drink consumption, type of milk, and calcium …
Physical Activity And Changes In Abdominal Fat Over 18 Months: A Prospective Study Of Middle-Aged Women, Lance Eric Davidson
Physical Activity And Changes In Abdominal Fat Over 18 Months: A Prospective Study Of Middle-Aged Women, Lance Eric Davidson
Theses and Dissertations
Objective: To investigate the extent to which changes in physical activity predict changes in abdominal fat in women over an 18-month period, while statistically controlling the effects of possible confounders, such as age, total body fat percent, and energy intake. Design: A prospective cohort design over 18 months. There was no intervention or treatment. Changes in objectively-measured physical activity were used to predict changes in abdominal fat over the study period. Subjects: 110 healthy, middle-aged women (mean: 41.3±3.3 yrs), primarily Caucasian, educated, and married. Measurements: An objective measure of physical activity (ACT) using CSA accelerometers, worn continuously for 7 consecutive …

A Comparison Of Youth Participation Motives In Organized Sports, Kirsty L. Carrihill
Legacy ETDs
Youth participation in organized physical activity has increased by more than 5 million in the last decade (Smith & Smoll, 2002). Of the 48 million youth 8 to 16 years old in the United States, 20 million participated in organized sport (Gould & Petlichkoff, 1998; Seefeldt & Ewing, 1997; Smith & Smoll, 2002). Currently, the average age for youth to begin participating in organized sports in, or outside of, school is 11 years old (Klint & Weiss, 1986; Smith & Smoll, 2002). Although participation rates have increased, there are significant numbers of youth who drop out of sport. Over one-third …

Gender Differences In Participation Of Physical Activities: A Comprehensive Model Approach, Kay Gordon Daigle
LSU Doctoral Dissertations
The purpose of this study was to examine the interrelationships among gender, perceptions of peer, parent, and teacher support, perceived value and meaningfulness, perceived competence, and the intention to be physically active within a proposed model. Female and male students (N=801) enrolled in a traditional multi-activity physical education class responded to a 52-item questionnaire addressing the constructs in the model. Structural equation modeling, using LISREL, was used to identify the relationships among the constructs. Gender differences emerged in this model through direct paths as well as indirect paths among these variables. Girls were more influenced than boys by their perceptions …
Collective Efficacy: A Framework For Understanding Classroom Teacher's Perceptions Of Integrating Physical Activity, Melissa Ann Park
Collective Efficacy: A Framework For Understanding Classroom Teacher's Perceptions Of Integrating Physical Activity, Melissa Ann Park
LSU Doctoral Dissertations
Children’s physical inactivity is becoming an important health concern, and it has been suggested by professionals that school programs can be important in the effort to increase activity levels. Physical education specialists cannot achieve the goal of significantly increasing children’s activity in isolation, and it is apparent that whole school programs at the elementary level have the potential to foster active lifestyles. If those programs are to be successful, all school personnel must play a role, so it is important to find ways to facilitate their involvement. The purpose of this study was to use collective efficacy as a framework …

Using Self-Determination Theory To Understand African American Women's Physical Activity Patterns, Joan B. Landry
LSU Doctoral Dissertations
Physical inactivity is a major health risk factor in our society. Women and minority populations are especially at risk with regard to physical inactivity. This three-part study employed quantitative and qualitative methodologies to investigate physical activity behaviors in middle aged and older African American women. This population was chosen because African American women are the least active segment of our society. In the first phase, a quantitative approach was used to investigate relationships between Self-Determination and the Stage of Change for physical activity in a sample of 105 African American women. This study provided validation for using this theoretical approach …
