Lifestyle behaviors, including diet and exercise, may mediate the risk of breast cancer recurrence. Large national and international organizations, including the American Cancer Society, the American Institute for Cancer Research, and the World Research Fund, recommend consuming a diet high in plant-based foods, specifically fruits, vegetables, and whole grains, and low in dietary fat and added sugar for cancer recurrence prevention. In addition, these organizations recommend regular physical activity, typically 30 minutes of moderate to vigorous activity per day. However, many cancer survivors unfortunately fall short of meeting these recommendations. In addition, low-income, and racial/ ethnic minority populations, especially Latinas, are at increased risk of breast cancer recurrence due to a myriad of factors such as limited access to health care. Theory-based, behaviorally-focused, and culturally-tailored nutrition and physical activity education has been shown repeatedly to improve these lifestyle behaviors in other populations. Previous intervention studies by our research group have significantly improved dietary behaviors among Hispanic/ Latina breast cancer survivors. This dissertation consists of a review of the educational literature on diet and physical activity studies among breast cancer survivors, and three studies: (1) a methodological description on the development of a theory-based, behaviorally focused intervention with classroom and online education curricula, (2) an empirical validation study of a survey instrument, and (3) a cross sectional study of women's diet and physical activity behaviors and theory-based determinants. Taken together, these studies can inform future educational interventions with this population by using our culturally-tailored, theory-based, behaviorally-focused model as a framework and by using our validated assessment tools. These studies can also inform future educational interventions by understanding diet and physical activity behaviors and related potential mediators.

520 $a These dissertation activities were conducted within the context of a larger, on-going, two-by-two factorial designed National Cancer Institute (NCI) funded educational intervention study, Mi Vida Saludable (My Healthy Life), which aims to change diet and physical activity behaviors of Hispanic/ Latina breast cancer survivors. The main study will examine the separate and synergistic effects of a) online education and b) in-class education. The intervention is based upon nutrition education curricula developed by the non-profit organization Cook for Your Life, which develops recipes and cooking education for cancer patients and survivors in New York City and a previous intervention conducted by this research group, that targeted fruit, vegetable, and dietary fat intake only. The on-going larger study, Mi Vida Saludable, involves cohorts of 30-40 Hispanic/ Latina breast cancer survivors who go through the intervention arms, at intervals of every 4-8 months, depending on recruitment. As of April 2018, two of the five planned cohorts have completed the study, and four of the five cohorts have been randomized.
520 $a The purpose of the initial comprehensive review of the literature was to inform the development of this Mi Vida Saludable educational intervention. Three areas relevant to the intervention were reviewed. The first area was the varying dietary and physical activity guidelines, both for cancer survivors, and also for common simultaneously occurring lifestyle-related diseases such as heart disease and diabetes. Similarities and differences were examined, and the resulting recommendations were used in the intervention development. The second area of review consisted of dietary and physical activity interventions that specifically targeted breast cancer survivors. Commonalities of successful interventions included the use of Social Cognitive Theory and the Stages of Change construct of the Transtheoretical Model. Finally, the text message literature was reviewed as it pertains to weight management, dietary, and physical activity behaviors, specifically among Hispanic/ Latina populations. Findings indicated that text message interventions were more successful if they decreased in frequency over time, included specific educational advice, and had the ability for two-way communication. The findings from these literature reviews were used to develop the Mi Vida Saludable intervention.
520 $a (1). The methodological study involved the development of the content of the Mi Vida Saludable group education and electronic ("e-")-communication programs. These programs were developed using a systematic stepwise theory-based, behaviorally-focused process, the Nutrition Education DESIGN Procedure. Briefly, DESIGN stands for: 1. Decide behaviors; 2. Explore determinants or potential mediators of change; 3. Select theory; 4. Indicate objectives; 5. Generate plans; and 6. Nail down evaluation. DESIGN was applied to help assure the curricula a) enhance motivation and b) facilitate action to change the following behaviors: 1) increase fruit and vegetable intake, specifically focused on non-starchy varieties, 2) decrease dietary fat intake operationalized as less fatty meats, decreased fat added during cooking, and smaller portions of cheese, 3) decrease added sugar intake operationalized as fewer sugar sweetened beverages and less added sugar in processed food and cooking, and 4) increase daily moderate-to-vigorous physical activity.
