Description
Fruit and vegetable (FV) consumption continues to lag far behind US Department of Agriculture (USDA) recommendations. Interventions targeting individuals' dietary behaviors address only a small fraction of dietary influences. Changing the food environment by increasing availability of and excitement for FV through local food production has shown promise as a method for enhancing intake. However, the extent to which local production is sufficient to meet recommended FV intakes, or actual intakes, of specific populations remains largely unconsidered. This study was the first of its kind to evaluate the capacity to support FV intake of Arizona's population with statewide production of FV. We created a model to evaluate what percentage of Dietary Guidelines for Americans (DGA) recommendations, as well as actual consumption, state-level FV production could meet in a given year. Intake and production figures were amended to include estimates of only fresh, non-tropical FV. Production was then estimated by month and season to illustrate fluctuations in availability of FV. Based on our algorithm, Arizona production met 184.5% of aggregate fresh vegetable recommendations, as well as 351.9% of estimated intakes of Arizonans, but met only 29.7% of recommended and 47.8% of estimated intake of fresh, non-tropical fruit. Much of the excess vegetable production can be attributed to the dark-green vegetable sub-group category, which could meet 3204.6% and 3160% of Arizonans' aggregated recommendations and estimated intakes, respectively. Only minimal seasonal variations in the total fruit and total vegetable categories were found, but production of the five vegetable sub-groups varied between the warm and cool seasons by 19-98%. For example, in the starchy vegetable group, cool season (October to March) production met only 3.6% of recommendations, but warm season (April to November) production supplied 196.5% of recommendations. Results indicate that Arizona agricultural production has the capacity to meet a large proportion of the population's FV needs throughout much of the year, while at the same time remaining a major producer of dark-green vegetables for out-of-state markets.

Description
Objectives Through a cross-sectional observational study, this thesis evaluates the relationship between food insecurity and weight status, eating behaviors, the home food environment, meal planning and preparation, and perceived stress as it relates to predominantly Hispanic/Latino parents in Phoenix, Arizona. The purpose of this study was to address gaps in the literature by examining differences in "healthy" and "unhealthy" eating behaviors, foods available in the home, how time and low energy impact meal preparation, and the level of stress between food security groups. Methods Parents, 18 years or older, were recruited during two pre-scheduled health fairs, from English as a second language classes, or from the Women, Infants, and Children's clinic at a local community center, Golden Gate Community Center, in Phoenix, Arizona. An interview, electronic, or paper survey were offered in either Spanish or English to collect data on the variables described above. In addition to the survey, height and weight were collected for all participants to determine BMI and weight status. One hundred and sixty participants were recruited. Multivariate linear and logistic regression models, adjusting for weight status, education, race/ethnicity, income level, and years residing in the U.S., were used to assess the relationship between food security status and weight status, eating behaviors, the home food environment, meal planning and preparation, and perceived stress. Results Results concluded that food insecurity was more prevalent among parents reporting lower income levels compared to higher income levels (p=0.017). In adjusted models, higher perceived cost of fruits (p=0.004) and higher perceived level of stress (p=0.001) were associated with food insecurity. Given that the sample population was predominately women, a post-hoc analysis was completed on women only. In addition to the two significant results noted in the adjusted analyses, the women-only analysis revealed that food insecure mothers reported lower amounts of vegetables served with meals (p=0.019) and higher use of fast-food when tired or running late (p=0.043), compared to food secure mothers. Conclusion Additional studies are needed to further assess differences in stress levels between food insecure parents and food insecure parents, with special consideration for directionality and its relationship to weight status.

Description
The objective of this study was to access whether there were any associations between food insecurity, weight status and emotional eating for adults and youth, and to discover whether emotional eating was prevalent for both age groups. By gathering participants from six various low-income housing communities throughout the Phoenix, Arizona, the researchers were able to gather data from 114 participants, 57 adults and 57 youth. The participants were a convenience sample, and were recruited by flyers sent via the mail and door-to-door announcements in the spring and summer of 2014. The adult and youth were asked to complete a survey that was part of a larger study, which included the Weight-Related Eating Questionnaire to access the participants' emotional eating. The participants' height and weight were measured manually and were integrated into the BMI system, and the participants' food insecurity statuses were validated using the US Household Food Security Survey. The results of the study illustrated associations between food insecurity and emotional eating for adults, but not for youth. In addition, there were no associations between adults' emotional eating and their child's emotional eating. The results from this study were consisted with the current research examining the associations of food insecurity and emotional eating, where there is only a correlation between food insecurity and emotional eating for adults. However, this study was not consistent with past research accessing the associations between adults' emotional eating and their child's emotional eating since this study found no relationship between the two. Being that a cross-sectional survey-based research was incorporated into this study, further research needs to explore on food insecurity, weight status and emotional eating to determine their causality.

Description
Objective: Fewer than 50% of female college freshmen meet physical activity (PA) guidelines. Innovative approaches that help college women increase their PA are warranted. The study purpose was to pilot test a magazine-based discussion group for improving PA, self-worth, and nutrition behaviors in freshmen college females. Method: Thirty-seven women (18-20 years) were randomized to intervention (n=17) and control (n=20) groups. The intervention group participated in an 8-week magazine-based discussion group adapted from a previously tested social cognitive theory based intervention, Fit Minded. Excerpts from a popular women's health magazine were discussed during weekly meetings incorporating PA, self-worth and nutrition education. The control group did not attend meetings, but received the magazines. Outcomes and feasibility measures included: self-reported PA, general self-worth, knowledge self-worth, self-efficacy, social support, and daily fruits, vegetables, junk food, sugar-sweetened beverage consumption. Results: Twelve participants from the intervention group attended more than 75% of meetings. A time effect was observed for PA (p=0.001) and family social support (p=0.002). Time x group effects were observed for PA (p=0.001), general self-worth (p=0.04), knowledge self-worth (p=0.03), and daily sugar-sweetened beverage consumption (p=0.03), with the intervention group reporting greater increases in PA, general self-worth and knowledge self-worth and greater decreases in daily sugar-sweetened beverage consumption. Although not significant, the intervention group demonstrated positive trends in self-efficacy, friend social support and fruit and veggie consumption as compared to the control group. Conclusion: A magazine-based discussion group may provide a promising platform to improve PA, self-worth and nutrition behaviors in female college freshmen.

Neophobia is a sensory phenomenon common in children that makes novel foods taste unpleasant. Our study tested exposure and pairing effects on neophobia in children by exposing them to novel vegetables paired with varying textures. Results showed a significant increase in liking for all subject groups after six exposures, which is less exposure than required in other studies. Except in one case, texture was not related to a change in liking that differed significantly from other groups.

Description
Photovoice is a participatory action research method that was used to investigate the food access and food choices of youth in low-income, high-obesity communities of urban Phoenix. To better understand the challenges adolescents face when making the conscious decision to eat healthy, impactful methods of photovoice, surveys and focus groups were used. This study investigated food access and food choice perceptions of adolescents aged 10-14 years old that were enrolled in ASU-Mayo Clinic Obesity Solutions, FitPHX Kids Energy Zones. Overall, the findings of this thesis present many interwoven barriers preventing low-income inner-city youth from eating healthy. Results from the study suggest that the four main barriers to healthy eating are the abundant access to unhealthy food, misunderstanding of a healthy diet, intrapersonal sentiments toward unhealthy food choices and emotional conflicts toward eating. Together those barriers create a complex environment conducive to unhealthy eating.

Description
OBJECTIVE: Freshman year at college is a time in an adolescent's life marked by a large amount of change in environment, as well as a shift in peer influences. Past research has shown that there are a variety of influences both personal and socio-environmental that affect weight control behaviors in college freshmen. This study examined the relationship between unhealthy weight control behaviors (UWCB) and two different personal and socio-environmental factors: time spent on each meal, and the perception that friends are partaking in UWCB. The Social Cognitive Theory was used to explain the intricate and intertwined association between the personal and socio-cognitive factors. METHOD: Unhealthy weight control behavior was assessed from first-year university students (n= 1241) living in campus dorms at Arizona State University. Demographics included Male (n=438) Female (n=802) first-year students with an average age of 17.5 years from various ethnic backgrounds. This was a secondary analysis of the devilSPARC study at Arizona State University and students completed a check-in survey upon participation. The survey asked for an estimation of time spent at meals and also asked the students to determine the individual's use of unhealthy weight control behaviors (vomiting, dieting, diet pills, steroids, substances, and protein shakes) as well as the observation of friend's participating in weight control behaviors. Students received a $15 Amazon gift card and devilSPARC swag as an incentive for participating. All participation was voluntary. RESULTS: This study found that unhealthy weight control behaviors were associated with spending more time on meals; this was relevant during the breakfast period. As well, the use of unhealthy weight control behaviors was associated with friends participating in unhealthy weight control behaviors in regards to both unhealthy weight loss and weight gain behaviors. CONCLUSIONS: These findings suggest both personal and socio-environmental factors affect the use of unhealthy weight control behaviors in college freshmen. Interventions for education should focus on body image and healthy weight control behaviors for college freshmen, intervening both before individuals enter college, as well as during the first year at university. This research is an important contribution to the literature, as it examines unhealthy weight control behaviors in college freshmen and the potential influences they face that lead them to develop such behaviors. Future studies should delve deeper into researching the relationship between time spent eating and weight control behaviors, as that has not been extensively studied in the literature.

Description
High childhood obesity rates have resulted in many interventions to attempt to lower these rates. Interventions such as day camps, residential camps, therapy-based interventions and family-based interventions lead to changes in weight and self-esteem but family-based intervention leads to the longest-term success for children ages nine to 17. Analysis of the interventions was measured using tools such as BMI, BMI-percentiles, and weight. Psychological measures such as self-esteem, happiness, and quality of life analysis was preferred, however were not measured in all studies. While most interventions resulted in weight loss and increased self-esteem, results were often not long-term. Studies provided evidence that family-based therapy has potential to last long-term, however there is a lack of research. To determine the most effective childhood nutrition intervention research must conduct follow-ups for many years after the initial intervention to ensure they provide long-term results.

We faced many struggles of starting college together, one of which, being the difficulty of mealtime once you are officially on your own. To the two of us and many of our friends, it was difficult no longer having a meal that felt like it turned a house to a home. Our goal of this project was to help those who may be experiencing similar feelings.
For our Thesis Project we wanted to create a cookbook that was designed specifically for college students who are living in the dorms. Our cookbook includes recipes that are low cost and easy to make for beginners. To be sure to capture our target audience, our cookbook will only included recipes which can be created using the given appliances in most standard dorms, which are limited to a microwave, blender, refrigerator and small freezer.
For the recipes specifically, we used a lot of family recipes and recipes from peers and colleagues. A great deal of time was spent actually testing out the potential recipes so we could narrow down which would be best for our book.
As two seniors who have grown immensely over the past few years at Arizona State, we recognize the issues that students may face when moving into a dorm. It was our goal to use our own experience and knowledge combined with research of those people who have also gone through this process, to create a book that we feel would have tremendously helped us navigate through our freshman year of college.

Description
Polycystic ovary syndrome (PCOS) is an endocrine-metabolic disorder found in 5-10% of reproductive-aged women, and is characterized by symptoms such as increased blood-sugar levels and increased androgen production, which can cause a multitude of complications, including obesity, high blood-pressure, type-2 diabetes, infertility, acne, hirsutism, and much more. All of this is predicted to be the outcome of genetics, excess insulin production, low-grade inflammation, and/or hyperandrogenaemia. In attempt to reduce these experienced symptoms/causes, it is suggested that women with PCOS adopt healthy and balanced diets that incorporate foods low on the glycemic index, high in fiber, and low in anti-inflammatory properties, to help reduce insulin levels and low-grade inflammation. This dietary alteration should also be coupled with other lifestyle changes such as exercise, stress-reduction techniques, and, if needed, medications such as oral contraceptive pills and/or metformin to help regulate hormones and insulin levels. While further research needs to be conducted, these dietary considerations may help to alleviate the symptoms experienced by women with polycystic ovary syndrome.
