The incidence of overweight conditions among children and adolescents is a growing national concern. Although current literature suggests that parental health behaviors could influence health behaviors of children, studies have not explored the actual predictive relationships of parents' and their children's weight statuses and weight-related behaviors. In addition, current studies have not tested the influence of parental authority, family communication, or demographic characteristics on the relationships. This study first examines factors that contribute to overweight conditions among children and adolescents and the associated costs. Studies of interventions that target children's and adolescents' weight-related health are then reviewed and provide evidence that parental involvement contributes to intervention success. The theory of planned behavior, social cognitive theory, social action theory, and systems theory are discussed and support the notion that parental influences contribute to the development of children's weight-related health behaviors. To test the relationships, 151 young adults and their parents were recruited and completed a series of questionnaires to describe their weight statuses, dietary behaviors, and physical activity behaviors. In addition, the young adult participants completed questionnaires to further describe their parents' parental authorities and their family communication environments during childhood and adolescence. Comparisons of body mass index, average daily energy consumption, average weekly energy expenditure, and physical activity enjoyment of young adult participants and their parents were conducted with correlation analyses and paired-samples t-tests. Further, multiple regression analyses were used to explore the influence of parental authority and family communication, and demographic characteristics were also considered. The empirical results of the current study indicate that, overall, parents' weight statuses and dietary behaviors help predict weight statuses and dietary behaviors of their young adult children. Further, parental authority scales interact with the relationships. At high levels of authoritarian and permissive parental authorities, young adults tend to have weight statuses that are opposite to those of their parents; at high levels of authoritarian parenting, young adults also tend to follow opposite dietary consumption patterns. The findings in this study have implications for professional practice, parenting practices, and the design of intervention activities. Recommendations for future research are provided.

Patronage behavior was investigated in this study with regard to the nutrition orientation of consumers. The objective of this research was to determine if consumers' patronage behavior of grocery stores, health food stores or restaurants would be significantly related to attitudes and concerns toward nutrition and toward attitudes of their overall present and future state of health. This study relied on theories of retail patronage behavior, and empirical evidence from areas of consumer behavior, nutrition, and health to provide the framework for the design of this research. This study employed the use of a questionnaire as the research method. Consumers were surveyed and asked to indicate their patronage and food purchase behaviors, their attitudes and concerns toward nutrition, and their attitudes toward their preventive health. Results and conclusions from this research support the linkage between the nutritional motivations of consumers impacting upon their decisions to patronize specific retail food establishments. That is, consumers' predispositions concerning nutrition influence where and what types of food products are purchased. / Master of Science

The possibility that faulty expectations about success and relapse recovery contributed to poor adherence was examined in this study. Support for such an expectancy model was sought through comparing an index of relative task magnitude to adherence rates. Instructions designed to improve adherence through changing expectations about relapse and relapse recovery were also administered to 46 clients in two clinical nutritional programs. Their adherence rates <in days) were compared to the rates obtained from the records of 64 other clients who did not receive the instructions. To further understand the adherence phenomenon, several other measures were obtained from the treatment subjects. These data were compared to adherence rates in an attempt to identify potential co-variate relationships. Statistical procedures including analysis of variance to determine comparability of subject groups, Pearson Product Moment correlations, t tests of the difference between means, and the Lawshe—Baker Nomograph comparing per cent adherence rates were performed on the data. Obtained results did not support the predicted relationship between relative task magnitude and adherence. This may have been due to differences between subjective assessments of task magnitude and the objective measure used in this study. Although improvement in adherence was noted in both treatment groups, statistical significance was achieved only in the university based clinic. Differences in the settings, assisting nutritionists, and participating subjects could have produced these findings. However, because improvement did occur in both settings, and because the techniques may be easily and inexpensively utilized by clinical nutritionists, these instructions were recommended for inclusion as a routine component of nutritional clinic procedures. No strong co-variate relationships were found between adherence and the additional measures included in the study. The only variables which correlated with adherence more than trivially, emotional response to a verbal food stimulus, and imaging ability, did lend support for this cognitively active method of improving adherence.

The present study employed a quantitative, non-experimental, multivariate correlational research design to test a hypothesized model examining associative paths of influence between ecological factors and weight status of urban, African-American adolescent females. Anthropometric and self-report survey data of 182 urban, African- American adolescent females were collected during after-school programs, health and physical education classes, and community events in an urban area in northeast Florida. Descriptive analyses were conducted to characterize the study participants based upon their age, study setting, and weight status. A scale reliability analysis was conducted to assess the internal consistency reliability of the sample data using selected measures within the context of the study’s specific population and subsequently guided the structural equation model (SEM) analyses. The SEM path analysis was used to develop two measurement models to control for observed error variance for variables demonstrating poor internal consistency reliability (diet behaviors and nutrition selfefficacy) and a final structural model to test the associative paths of influence between latent (diet behaviors and nutrition self-efficacy) and manifest variables (teacher social support and friend social support) on weight status. The results of the path analysis indicated that both teacher social support and friend social support demonstrated a positive, indirect influence on child weight status through nutrition self-efficacy and diet behaviors following two different and specific paths of influence. Diet behaviors, in turn, demonstrated a positive, direct effect on child weight status. These findings provide clear implications for educational leaders that call for the integration of health behavior change theory into traditional education and leadership practice and actively addressing the childhood obesity epidemic in the school environment by implementing health behavior change strategies at various ecological environmental levels.
