Association Between The Frequency Of Physical Education Classes And The Prevalence Of Overweight/Obesity In Adolescents, Collin N. Rice
Theses and Dissertations
Background/Objective: Overweight and obesity has been steadily on the rise in the United States for all groups. The prevalence of obesity for adolescents has tripled since 1980. The purpose of this study is to determine an association between the frequency of physical education classes and the prevalence of overweight/obesity in adolescents in the United States.Methods: This was a cross-sectional study that used the 2001 Youth Risk Behavior Survey (YRBS) of the Center for Disease Control. The outcome variable for the study was Body Mass Index (BMI). A BMI of 25 or greater was considered overweight or obese. The main independent …
Toothbrushing, Flossing, And Preventive Dental Visits By Richmond-Area Residents In Relation To Demographic And Socioeconomic Factors, Kim T. Isringhausen
Toothbrushing, Flossing, And Preventive Dental Visits By Richmond-Area Residents In Relation To Demographic And Socioeconomic Factors, Kim T. Isringhausen
Theses and Dissertations
Purpose. This study was conducted to identify factors that influence preventive dental behaviors and, from the results, target groups for intervention.Methods. Data were collected using the 1997 Behavioral Risk Factor Surveillance System (BRFSS) resulting in a probability sample of 399 dentate adults living in Richmond City, Henrico, Chesterfield and Hanover Counties in Virginia. All analyses were performed using the statistical software program STATA. Initial hypothesis testing was performed using univariate logistic regression models. Multivariate logistic regression models were used to test the significance of independent variables while controlling for other possible predictors of behavior.Results. Females were more likely than males …
Effect Of Repeated Dosing Of Delta 9-Tetrahydrocannabinol, The Major Psychoactive Ingredient Of Marijuana, On Memory In Mice, Floride Niyuhire
Effect Of Repeated Dosing Of Delta 9-Tetrahydrocannabinol, The Major Psychoactive Ingredient Of Marijuana, On Memory In Mice, Floride Niyuhire
Theses and Dissertations
Purpose: Marijuana is the most widely used illicit drug in the United States. However, marijuana and cannabinoid derivatives have potential therapeutic uses. Studies in cannabis users have yielded contradictory results with regard to long-term effects on cognitive functions. There is no prospective study assessing this issue, and such studies may raise ethical issues in humans, whereas mice have been shown to exhibit similar cannabinoid-mediated behaviors as humans. The purpose of this study was to assess the consequences of chronic administration of Δ9-THC, the major psychoactive component of marijuana, in a mouse memory model. Methods: In Experiment 1, the dose-response relationship …
Antioxidants As Risk Factors For Gingival Bleeding, Hee-Jeong Bahng
Antioxidants As Risk Factors For Gingival Bleeding, Hee-Jeong Bahng
Theses and Dissertations
Background: Studies of gingival bleeding and the effects of antioxidants on extracellular matrix and immunologic and inflammatory responses provide a rationale for hypothesizing that antioxidants reduce the risk for gingival bleeding.Methods: This study evaluated the role of antioxidants as contributing risk factors for gingival bleeding utilizing the Third National Health and Nutrition Examination Survey (NAHNES III). A sample of 18,825 adults (20 to ≥ 90 years of age), with dental measurement and assessment of serum levels of antioxidants were included in the study. Gingival bleeding was defined as those who had more than 30 percent of gingival bleeding in 28 …
Determinants Of Prenatal Care And Supplement Use: The Case Of Honduras, Catherine E. Henze
Determinants Of Prenatal Care And Supplement Use: The Case Of Honduras, Catherine E. Henze
Theses and Dissertations
Context: Literature suggests that prenatal care and prenatal supplement use improves pregnancy outcomes. However, we do not know the factors associated with prenatal care and supplement use in Honduras.Objective: To identify characteristics of Honduran women who are the least and most likely to use prenatal care and supplements.Methods: Data from a 2001 Honduras cross-sectional survey of women was used to assess their use of prenatal care and supplements. All data was weighted, resulting in a sample size of n = 5647 women who had a live birth since January 1996. Bivariate and multivariate analyses were used to examine factors associated …
Rabies In Virginia, 1989-2003: With Particular Attention To Animals, Geographic Distribution, And Virus Variant, William Andrew Holzgrefe
Rabies In Virginia, 1989-2003: With Particular Attention To Animals, Geographic Distribution, And Virus Variant, William Andrew Holzgrefe
Theses and Dissertations
Objectives: The description of the raccoon rabies epizootic in Virginia over fifteen years (1989-2003). Methods: Using simple statistical methods and a geographic information system (GIS)-based approach, and fifteen years worth of animal surveillance data, the progress of this epizootic has been charted in terms of the geographic spread of the disease, the major animal species affected by the disease and its spread, and the exposure and risk to humans and livestock animals presented by the expansion of the geographic range. Results: The resulting descriptive study illustrates the eastward expansion of the epizootic, the mushrooming of the disease in the northern …
