<p> The purpose of this paper is to determine whether zoning regulations constrain the builder in his or her ability to provide low-income housing units in Hamilton. It critically reviews five impediments to the provision of low-income housing and the application of urban managerialism to the low-income housing supply problem. An explanation of the degree to which the zoning revision process impedes large and small builders is given. An examination of three specific dimensions of zoning and the extent to which these dimensions constrain the builder follows. These dimensions are (i) inflexibility, (ii) the procedural and temporal framework and (iii) "full-up" zones. The analysis showed insufficient evidence existed to substantiate or falsify the hypothesis that zoning regulations impede the builder's ability to provide low-income housing units. </p> / Thesis / Bachelor of Arts (BA)

Results indicate that structural factors are highly predictive of paternal commitment and paternal involvement among low-income African American fathers, thus lending strong credence to the structural barriers perspective. Moreover, while findings also indicate that several cultural factors are associated with paternal involvement (e.g., attitudes toward single motherhood and low self-efficacy), they are at odds with the cultural deficiency perspective. These results have both theoretical and policy implications. With respect to fatherhood theory, findings derived from this research call for a much-needed theoretical integration in studying paternal commitment and paternal involvement among low-income African American fathers; that is, to synthesize and integrate a structurally sound theory with a culturally sensitive approach, such as the cultural resiliency perspective. This research also suggests that public policy-makers should be aware of the adaptive strategies that many low-income African American fathers employ in order to be actively involved with their children, especially those who are young.

The prevalence and severity of childhood overweight has climbed dramatically in the past three decades and is recognized as a serious public health concern that requires urgent action. The home environment has been identified as a key influence on the diet and physical activity of children. Furthermore, low-income families experience obesity at higher rates and current interventions have not been translated from research to practice settings. Therefore, there is a need to evaluate the potential for evidence-based obesity treatment strategies to be translated into community or clinical delivery settings that reach broadly into the population of low-income families. In addition, while the home environment has successfully been targeted to treat childhood obesity, there is a paucity of measurement tools available to provide a comprehensive assessment of the home physical and social environment as it pertains to physical activity and dietary intake. This dissertation includes: (1) a mixed-methods study to determine the feasibility and effectiveness of a childhood obesity treatment intervention based on a partnership with a Health Care Organization and delivered through Cooperative Extension, (2) a systematic review of home environmental measures related to physical activity and dietary intake, and (3) a home environment measure development and validation study. Smart Choices for Healthy Families (SC) was developed through a research-practice partnership that included a local healthcare provider (Carilion Clinic), Virginia Cooperative Extension (VCE), and an interdisciplinary research team. The aim of this study was to assess the reach, implementation, and effectiveness of SC to reduce the BMI z-scores of overweight and obese children from low-income families. The resultant intervention, based on an evidence-based social-ecological model, included brief physician counseling and referral, six-biweekly group sessions taught by VCE lay leaders, and six automated telephone counseling calls on alternate weeks. Twenty-six of 264 eligible children (50% boys; mean age=10.5 years) were recruited and 78% completed baseline and 3-month assessments. Over the 6 class sessions, there was an average 65% attendance rate and an average 58% completion rate for the automated telephone calls. Results revealed a significant reduction in children's BMI z-score (p<0.01), an increase in lean muscle mass (p<0.001) and weight (p<0.05), and an increase in Health Related Quality of Life (HRQL; p<0.0001). The participating group had a higher income (p<0.05) and also participated in fewer food assistance programs (p<0.05). Despite this small difference, Smart Choices reached a sample that was representative of the larger target population and was effective in reducing BMI z-score, increasing lean muscle mass, and improving HRQL of low-income obese children. A systematic review was conducted of the measures of the home environment in order to collect and synthesize the current body of literature. It was found that some authors choose to use non-validated measures and that there is an inconsistent use of measures across the field, making comparisons between studies difficult and conclusions regarding parental influence on childhood obesity difficult to discern. The psychometric properties that were reported on these studies are reported in this review. Through the systematic review of literature a number of measures were identified that assessed different aspects of the home environment. These measures were compiled and combined to generate a comprehensive tool to assess the physical and social aspects of the home environment that could influence eating and physical activity. This measure plus a social-ecological framework for the measure were provided to experts in the field who provided information on potential areas that had been overlooked and advice on additions or contractions of items and scales. The modified measure, the Comprehensive Home Environment Survey (CHES), was then tested for reliability and validity in a low-income audience. Parent-child dyads (n=132; Children 47% girls, age range 5 to 17; Parent 82% mothers; mean age=36) were recruited through a pediatric clinic in Roanoke, Virginia, that serves a primarily low-income audience (i.e., 95% eligible for Medicaid). Each of these parents completed the assessment tool and additional surveys to assess concurrent and predictive validity. Height and weight was assessed in each child, and children between the ages of 9 and 17 also completed nutrition and physical activity self-report surveys. Test-retest reliability was assessed in 43 parents who complete the survey a second time one-to-two-weeks following the initial assessment. Inter-rater reliability was assessed in 36 cases by having a spouse or second care-giver complete the assessment tool. Internal consistency, test-retest, inter-rater reliability, and predictive validity all showed promising results. Across the scales internal consistency was adequate to high with Cronbach's Alphas ranging from 0.67-0.92, test-retest reliability was high with Pearson Correlations ranging from 0.73-0.97 and inter-rater reliability was higher with Pearson Correlations ranging from 0.42-0.92. Finally, the CHES displayed predictive validity with subscale scores predicting outcome behaviors (e.g., parents who modeling more physical activity had children who were more active). This dissertation demonstrated that the home environment is a key factor in the treatment of childhood obesity and provides avenues for both intervention and measurement in this field of study. / Ph.

Low-income older adults are at high risk for developing diet-related chronic diseases. Nutrition education programs can improve dietary and lifestyle practices, thereby decreasing the incidence of diet-related diseases. Focus groups were conducted to gain insight into the needs and preferences of low-income older adults for nutrition education. Results were made available for use in the Smart Choices Nutrition Education Program at Virginia Tech to aid in the development of nutrition education programs. Four focus groups were conducted with a total of 35 elderly (28 females; 7 males), ages 55-90+ years, recruited from Congregate Meal Program sites in four regions of Virginia. Seventeen were African American, and 18 were non-Hispanic white. Discussion questions addressed practices for purchasing and preparing foods, importance of food to health, and preferences for education methods. The Determine Your Nutritional Health Checklist of the Nutrition Screening Initiative was used to assess nutritional risk of the elderly adults. Focus group discussions were audio-taped and written transcripts were made for use in data analysis. Themes of the discussions were identified in that analysis and reported in the following broad areas: Factors that Influenced Dietary Practices of Focus Group Participants and Perceived Needs and Preferences of Focus Group Participants for Nutrition Education. All elderly believed that food was important to their health and were interested in nutrition education. The predominant theme was the influence of a health condition on dietary practices. The elderly made food choices according to dietary restrictions imposed by their health condition. The most prevalent health conditions were chronic diseases, primarily hypertension, diabetes, and hiatal hernia. The majority (32) were at nutritional risk, with a larger number at high risk (20) than at moderate risk (12). Food preferences and sensory attributes of food also were important to them when making food choices. Some reported that convenience was important because they did not want to spend time and effort to purchase and prepare foods. Some also reported experiencing food insecurity, primarily from lack of money. The majority learned about food and cooking from family members, and only a few learned about nutrition and food choices from health professionals. Most wanted information about disease-specific food choices and preparation methods, and preferred to receive this information during group discussions because sharing ideas and opinions was an effective way to learn. Only a few were interested in television programs, while many were interested in written materials. Nutrition education programs for low-income elderly should teach these adults how to choose and prepare foods that are appealing and nutritious, as well as within dietary restrictions imposed by their health conditions. Educators should convey this information to them in group settings and distribute written materials, such as pamphlets and brochures, that outline "how-to" information. / Master of Science
