Description
Availability and accessibility of foods in the home influence dietary behaviors. However, much of the literature involving measurement of the home food environment (HFE) has examined only self-reported data, and home food inventory tools have not been used to assess behavior change intervention efficacy. Thus, this quasi-experimental study was conducted to test the preliminary efficacy of a 10-week dietary behavioral intervention on the HFE, measured through the presence of fruits, vegetables, and sources of sugars in the household. Participants included 23 parents (21 females; age=36±5.5) of children 6-11 years old living in an ethnically diverse community within a Southwestern metropolitan area. Sociodemographic information was collected at baseline using a survey. A modified version of the Home Food Inventory was completed in the homes of participants by trained research assistants at baseline and following termination of the intervention. Relative to baseline, the intervention resulted in significant increases in availability of different types of fruits (7.7±3.2 vs. 9.4±3.1; p=0.004) and high fiber/low sugar cereal (2.3±1.4 vs. 2.7±1.4; p=0.033). There was a significant reduction in availability of sugar-sweetened beverages (3.2±1.9 vs. 1.7±1.3; p=0.004), and an increase in the number of households with accessible 100% fruit juice (3 vs. 17 households; p=0.001) and bottled/contained water (9 vs. 22 households; p<0.001). Moreover, there were meaningful changes in the number of households with accessible chocolate milk (7 vs. 0), strawberry milk (3 vs. 0), and diet soda pop (2 vs. 0). There was a significant increase in the number of households with accessible ready-to-eat vegetables (8 vs. 19 households; p=0.007), and ready-to-eat fruit (8 vs. 17; p=0.022), and a significant reduction in available prepared desserts (3.0±2.0 vs. 1.7±1.3; p=0.005), and candy (2.0±1.7 vs. 0.6±0.7; p<0.001). There were no significant changes in availability of vegetables and sugar-laden cereals, or accessibility of fresh fruit, fresh vegetables, dry cereal, candy, soda pop, desserts, and sports/fruit drinks. Overall, results suggest that the current dietary behavior change intervention resulted in positive changes in the HFE. Further research to confirm these results in a randomized controlled trial is warranted.

Description
Food banks are the foundation of the emergency food network, and while their chief mission is to mitigate hunger, the rise in obesity and other diet-related diseases among clientele has incited the need for better nutritional control with regards to procurement of inventory at food banks. The purpose of this research was to determine if procured inventory at United Food Bank in Mesa, Arizona could meet minimum MyPlate recommendations for a typical food bank client and what implications the results could have for future policy. Inventory data was obtained from United Food Bank for fiscal year 2013-2014 and analyzed utilizing the MyPlate Analysis Program to determine contributions of each food category to MyPlate recommendations. Inventory was separated by MyPlate food category and analyzed to determine contribution towards a meal built around MyPlate recommendations. Results showed that the inventory could meet the minimum requirements for protein and grains for a family of four for at least three days, the amount of time an emergency food box is designed to last. On the contrary, the inventory did not meet minimum vegetable, fruit or dairy requirements. These results indicate that typical food bank inventory does not meet USDA MyPlate recommendations and that having nutritional policy in place could potentially drive donations and purchases to enhance the nutritional quality of future food bank inventory.

Description
Background: The prevalence of childhood obesity has disproportionately affected Latino youth. This increase in obesity is seen with an increased incidence of Type 2 Diabetes. Objective/Hypothesis: The objective of this study was to determine the effects of a community based lifestyle intervention, which encompassed nutrition education and physical activity, on diabetes risk in pre-diabetic Latino adolescents. Diabetes risk was assessed using pancreatic beta cell function as measured by proinsulin: insulin ratio. It was hypothesized that reductions in added sugar intake and reductions in saturated fat intake will be associated with improved beta cell function as measured by proinsulin: insulin ratio. Study Design/Participants: In this quasi-experimental study design, n=17 pre-diabetic Latino adolescents between the ages of 14-16 participated in a lifestyle intervention. Methods: Anthropometric measurements (weight, height, waist circumference, BMI) and body composition (body %) were determined for all participants at baseline and post intervention. Fasting proinsulin (PI), fasting insulin (I) and 2hr-OGTT were also determined. Dietary intake was measured using the Block Kids Food Screener for kids ages 2-17y (2007). The intervention consisted of nutrition education classes and physical activity sessions for 12 weeks. Results: We found significant decreases in body fat % following the intervention. There were no significant decreases in fasting insulin. Proinsulin significantly decreased. However we did no see a significant change in PI/I (p= 0.003). Dietary behaviors of added sugar (p=0.03) and saturated fat (p=0.04) showed significant decreases. No significant associations were found between changes in added sugar to improvements in beta cell function, r=0.072, p-value= 0.7. We also did not observe significant associations between reductions in saturated fat intake and improvements in beta cell function, r=0.152, p-value =0.6. Conclusions: We concluded that a 12-week lifestyle intervention resulted in significant changes in dietary behaviors. These changes were not however associated with improvements in beta cell function.

Description
College weight gain and obesity are significant problems impacting our society, leading to a considerable number of comorbidities during and after college. Gut microbiota are increasingly recognized for their role in obesity and weight gain. Currently, research exploring the gut microbiome and its associations with dietary intake and body mass index (BMI) is limited among this population. Therefore, the purpose of this study was to assess associations between the gut microbiome, BMI, and dietary intake in a population of healthy college students living in two dorms at Arizona State University (n=90). Cross-sectional analyses were undertaken including 24-hour dietary recalls and anthropometrics (height, weight and BMI). High throughput Bacterial 16S rRNA gene sequencing of fecal samples was performed to quantify the gut microbiome and analyses were performed at phyla and family levels. Within this population, the mean BMI was 24.4 ± 5.3 kg/m2 and mean caloric intake was 1684 ± 947 kcals/day. Bacterial community analysis revealed that there were four predominant phyla and 12 predominant families accounting for 99.3% and 97.1% of overall microbial communities, respectively. Results of this study suggested that a significant association occurred between one principal component (impacted most by 22 microbial genera primarily within Firmicutes) and BMI (R2=0.053, p=0.0301). No significant correlations or group differences were observed when assessing the Firmicutes/Bacteroidetes ratio in relation to BMI or habitual dietary intake. These results provide a basis for gut microbiome research in college populations. Although, findings suggest that groups of microbial genera may be most influential in obesity, further longitudinal research is necessary to more accurately describe these associations over me. Findings from future research may be used to develop interventions to shift the gut microbiome to help moderate or prevent excess weight gain during this important life stage.

Description
Objectives. This study primarily explored the relationship between family meal frequency and youth intake of fruits and vegetables (FV) and added sugar from sugar-sweetened beverages (SSBs) in a population of Latinx parents and their middle school children. The study secondarily explored factors influencing family meal frequency; specifically, whether parent education level, income level, acculturation level, and food insecurity are associated with family meal frequency.
Methods. Latinx parents and their 6th-8th grade children were recruited from eligible middle schools in Maricopa County to participate in a larger intervention study. A sample of parent-youth dyads from the first cohort of the larger study was selected for cross-sectional analysis of baseline data in this study (n=124). Participants completed a survey requesting demographics, family meal habits, and dietary intake. Participants were asked to report annual income, education level, and number of family meals in the home in the past week. They were also asked to complete an Acculturation Rating Scale for Mexican Americans, a 6-item Household Food Security Questionnaire, and a 26-question Dietary Screener Questionnaire. Analyses were run using Spearman’s Rank Correlation test and a Chi Square test of Independence.
Results. Mean daily youth intake of FV was 2.7 ± 1.4 cup equivalents, and daily youth intake of sugars from SSBs was 8.6 ± 4.9 teaspoon equivalents per day. Fifty percent of parents reported 7 or more family meals per week, while 38.7% reported 3-6 family meals per week and 11.3% reported 2 or fewer family meals per week. There was no significant association between family meal frequency and youth FV (r=-0.154; p=0.256) or added sugar from SSBs (r=0.027; p=0.807) intake. Similarly, results from Chi Square analyses suggested there was no association between family meal frequency and parent income level (p=0.392), Mexican-oriented acculturation level (p=0.591), Anglo-oriented acculturation level (p=0.052) and food insecurity (p=0.754). In contrast, a significant association between parent education and family meal frequency was found (p=0.014).
Conclusions. Parent education may play a role in shaping family meal practices in Latinx families. More research is needed to further understand this relationship and the relationship between family meal habits and youth dietary intake.
