Prior research on eating behaviors has shown that romantic partners actively merge their dietary preferences throughout the course of a relationship and find significant value in cooking and eating the same foods together at the same times. Yet, little is known regarding the impacts of specific dietary support processes involved in maintaining said communal diet when one partner drastically alters his or her eating patterns. The current study defined dietary sacrifice as a phenomenon within the context of Celiac Disease (CD): a chronic illness that requires strict adherence to the gluten-free diet (GFD). Drawing from existing research on sacrifice within romantic relationships (e.g., Impett & Gordon, 2008), this project examined whether non-Celiac partners' adherence to the GFD during shared mealtimes impacted relationship satisfaction for both couple members. Female Celiacs and their non-Celiac cohabitating partners (N=152 couples) were recruited for an online survey through various support organizations. Given the dyadic design of this study, the Actor-Partner Interdependence Mediation Model (APIMeM; Ledermann, Macho, & Kenny, 2011) was used to examine the mediating influence of Dietary Approach and Avoidance Motives. Results indicated that partner support in the form of shared GFD adherence bolstered couple happiness to the extent that it was performed for positive gains (e.g., promoting health and well-being) by the non-Celiac. While dietary sacrifice was positively associated with Celiacs' relationship satisfaction above and beyond non-Celiacs' endorsement of Dietary Avoidance Motives, both dyad members experienced significantly lower relationship satisfaction when non-Celiac partners adhered to the diet to deflect negative outcomes (e.g., rejection, fighting). This study serves as the first application of relationship sacrifice research to a specific health issue, and the first psychological exploration into intimate partners' dietary support processes within the Celiac population.

Submitted in fulfilment of the requirements of the degree of Master of Technology: Nursing, Durban University of Technology, 2014. / South Africa has a high prevalence of obesity, and many people live with diseases where dietary adaptations are part of the management of the disease. Nurses are important in the facilitation of people obtaining dietary advice. While nutrition education is part of the nursing curriculum, student nurses’ knowledge of nutrition was not known, nor was their dietary intake and nutritional health status. The purpose of the study was to assess the nutrition knowledge of students at a nursing college, and to assess their dietary diversity. A quantitative study was used, with random sampling chosen for selection of campuses and convenience sampling for student group selection. Students of the KwaZulu-Natal College of Nursing were invited to complete a General Nutrition Knowledge Questionnaire. A Food Frequency Questionnaire was completed to assess dietary diversity, and respondents’ anthropometric measurements were recorded to assess Body Mass Index and Waist to Height Ratio. The results showed that a significant percentage of student nurses were overweight or obese. While students had a satisfactory knowledge of dietary recommendations and sources of different nutrients, their ability to make correct food choices, as well as their knowledge of diet-disease relationships was poor. They displayed good dietary diversity in their food intake. There were no statistically significant correlations between the students’ Body Mass Index and their knowledge, which assumes that the individual’s knowledge of nutrition does not directly influence their own food intake. It is recommended that aspects of the content in the nutrition curriculum be emphasised during the training of nurses in order to increase nutrition awareness in areas where knowledge was found to be lacking.

The aim of this exploratory qualitative study is to identify the problems African American adolescent girls face in making eating choices and to learn how they make decisions about eating. Differences related to culture and socioeconomic status influences, and decision-making strategies were explored. Three sites in African American communities were selected for focus groups and individual adolescent girl-parent dyad interviews for data collection. Data were gathered in 5 focus groups and 4 individual adolescent girl-parent dyad interviews with African American adolescents (n=30). Bronfenbrenner's Ecological Systems Theory (EST) provided the conceptual framework for informing the analysis and interpretation of the data. Using grounded theory methods, the researcher identified the core variable or basic psychosocial problem that faced the participants was receiving mixed messages. Low income African American adolescent girls receive mixed messages about nutrition, health and foods from their microsystems that are comprised of friends and family, and from macrosystems that include textbooks and the media. Filtering the mixed messages is the basic psychosocial process that low income African American girls use to handle the barrage of mixed messages they receive from their microsystems and macrosystems regarding eating choices and exosystem influences. The process of filtering the mixed messages is comprised of five phases: Applying a lens, surveying available resources, weighing influences, then choosing alternating eating strategies and evaluating their eating choices. How the adolescent girl applies a lens, surveys resources and weighs the influences together impact the alternating eating strategies that they implement. Over time they evaluate the effectiveness of their eating choices. / text
