Description
Background: The prevalence of childhood obesity has disproportionately affected Latino youth and can be seen with an increase incidence of Type 2 Diabetes. This increase in obesity can be attributed to physical inactivity. Increases in social support and self-efficacy are independently related to increases in physical activity. A lifestyle intervention can lead to increases in social support, self-efficacy and physical activity. Objective/Hypothesis: The objective of this study was to determine whether a 12-week lifestyle intervention could increase social support, self-efficacy and physical activity in obese Latino adolescents that participated in the intervention. It was hypothesized that adolescents that participated in the intervention would increase self-efficacy, social support from family and friends, and physical activity compared to their control counterparts. Study Design/Participants: In a randomized control trial, there were 125 Latino (n= 60 experimental group; n= 65 control group; mean age = 15.17 +- 1.65 Males n = 60; n = 65 females) participants included in this study. Participants were also required to have a BMI percentile >= 95th percentile for age and gender or BMI >= 30 kg/m2. Methods: The intervention, which was developed using the Social Cognitive Theory had components focusing on social support and self-efficacy and also consisted of nutrition education classes and physical activity sessions for 12 weeks. The psychosocial constructs of self-efficacy and social support were measured using the Adolescent Self-Efficacy for Diet and Activity Behaviors and Adolescent Social Support for Diet and Exercise Survey, respectively. Physical activity was assessed by the 3-day Physical Activity Recall. Results: We found significant increases in social support in family (p = 0.042) and vigorous physical activity (p = 0.001). There was also a significant difference between control and treatment group for moderate to vigorous physical activity after the intervention (p = 0.027). There were no changes in social support from friends or self-efficacy. Conclusion: We concluded that a 12-week lifestyle intervention did lead to changes in social support and physical activity behaviors. These changes could have been influenced by the intervention as they were measured these constructs pre/post intervention.

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
The purpose of this research was to analyze the EPODE Model for the development community-based interventions against childhood obesity and its transferability on a global scale. The Ensemble, Prevenons L'Obesite des Enfant (EPODE: Together Let's Prevent Childhood Obesity) Model was developed in France following the successful results of a community-based intervention there. The Model is illustrated by four pillars that are essential to program implementation and positive results. These pillars are: political support, research & evaluation, social marketing principles and public/private partnerships. Using these four pillars, the model has been transferred to diverse countries around the globe and has shown results in these diverse locations. In order to understand what makes this model so transferrable to so many diverse locations, this researcher traveled to the Netherlands, Belgium and France visiting program locations and interviewing professionals who have been involved in the development of the model, its modification and implementation. These interviews addressed specific modifications to the model that were made for implementation in the Netherlands and Belgium. This paper outlines the key transferrable components of this model and outlines a proposed model to be used in the United States.

Description
The purpose of this paper is to examine the current health status of children and adults in the United States as it relates to the current obesity epidemic. There will also be an examination of how nutrition education is commonly presented to children currently and how it was presented in a community-based health intervention, Athletes for Life, during a six-week pilot program of the intervention. Using the data compiled on the current health status of the population of the United States, the methods of intervention examined and the seemingly most effective means to relay nutrition information to school-age children, a coordinated nutrition curriculum will be proposed and implemented into the efficacy portion of Athletes for Life, a ten-week intervention.

Description
Childhood obesity is a worsening epidemic in the U.S. with substantial racial/ethnic and socioeconomic disparities. Community-based approaches are necessary to target populations that are disproportionately affected by childhood obesity. The current randomized controlled trial assessed the effects of Athletes for Life (AFL), a 12-week community-based nutrition education and physical activity program that aims to improve cardiovascular fitness and promote healthy eating among families in the South Phoenix region, relative to a control condition. One of the goals of the intervention was to increase participating children's intake of fruits/vegetables and reduce their sugar intake, measured by a parent-reported food-frequency questionnaire. Data were collected on 110 child participants aged 6-11 years old. Relative to baseline values, participants in the intervention reportedly increased their fruit intake frequency by 0.12 + 2.0 times per day, whereas the control group decreased their intake by 0.32 + 1.28 times per day (p=0.026). Participants in the intervention group also increased their vegetable intake by 0.21 + 0.65 times per day, whereas control participants decreased their intake by 0.05 + 0.72 times per day (p=0.019). Participants in the intervention group decreased their intake of sugar-sweetened beverage (SSB) intake by 0.22 + 0.62 times per day, whereas control participants decreased their intake of SSBs by 0.04 + 0.40 times per day, however, the change observed in SSB intake was not significant between groups. Lastly, frequency of sugar-laden food intake decreased by 0.86 + 1.10 times per day among the intervention group, whereas control participants increased their intake by 0.02 + 1.10 times per day (p=0.033). The AFL study may serve as a framework for future community-based interventions to promote health in underserved areas.

Description
Cultural beliefs and behaviors can serve as both risk and protective processes for Latino adolescents, with some recent empirical work suggesting the important protective role of bicultural values (e.g., endorsing high levels of both mainstream culture and culture of origin). We expanded on past research to explore whether bicultural values were associated with internalizing (depressive, anxiety, stress) symptoms and externalizing (alcohol use) symptoms among a sample of Latino adolescents preparing to begin college. We hypothesized biculturalism to protect against all negative outcomes. Our sample consisted of 209 college-bound Latino adolescents (65% female; 85.1% Mexican descent; 10.6% 1st generation, 62% 2nd generation) who were enrolled in university for the coming fall. All multivariate models included sex, ethnicity, parent education, and immigrant generation status as covariates. Correlations and multivariate analyses revealed that higher bicultural values were associated with lower depressive symptoms, lower anxiety symptoms, lower stress, and greater alcohol use. Gender was shown to moderate the relationship between biculturalism and alcohol use. Overall, findings suggested that greater bicultural values were associated with lower endorsement of internalizing symptoms for all participants, but higher endorsement of alcohol use over the last year for the highly bicultural females. Biculturalism may be particularly protective for Latino adolescents who are preparing to attend college given the need for them to transition into an environment with high acculturative demands. However, our results also highlight that these bicultural females may be at greater risk for alcohol use and related problems.

Description
Hispanic children have the highest prevalence of obesity versus other ethnic groups. This leaves this population susceptible to many adverse health risks, including hypertension, cardiovascular disease, and high blood pressure. Unfortunately, little research has been done investigating the contributing cause to this issue, specifically common sedentary behaviors in children that limit physical activity and it’s purpose in expending energy. Amongst these behaviors, amount of time spent on electronic devices has proven to have increased drastically in recent years. The relationship between screen time and electronic device use, specifically with television, video games, and computer usage, and physical activity levels, and how those affect cardiometabolic disease risk factors, were explored in this study. Participants of this study were elementary school-aged children from Maricopa County, AZ. Electronic device usage, physical activity amounts, and presence of the specific devices in the child’s were collected from the participants’ parents through self-reported survey questions. Anthropometric and biochemical markers of cardiometabolic disease risk were directly measured. The average time spent engaged in physical activity per day by these participants was 20.02 ± 21.1 minutes and the average total screen time per day was 655 ± 605 minutes. Findings showed strong significance between total screen time and computer and video game use (r=0.482; p=0.01 and r=0.784; p=0.01, respectively). Video game time in the group of children with a video game in their room (350.66 ± 445.96 min/day) was significantly higher than the sample of kids without one in their room (107.19 ± 210.0 min/day ; p=0.000). Total screen time was also significantly greater with children who had a video game system in their room (927.56 ± 928.7 min/day) versus children who did not (543.14 ± 355.11 min/day; p=0.006). Additionally, significance was found showing children with a computer in the bedroom spent more time using the computer per day (450.95 ± 377.95 min/day), compared to those children who did not have a computer in their room (333.5 ± 395.6 min/day; p=0.048). No significant association was found between metabolic markers and screen time. However, HDL-cholesterol, triglycerides, and insulin proved to be dependent on BMI percentile (r=-0.582; p=0.01, r=0.476; p=0.01, r=0.704; p=0.01 respectively). Our data suggest further research needs to be done investigating other potential sources that limit physical activity so that strategies can focus on reducing obesity incidence and the associated health risks. Future studies should use larger sample sizes to be more representative of this population, and develop more direct observations instead of self-reported values to limit bias.

Description
The purpose of this secondary data-analysis was to identify potential risk factors in the home at 12 months that can lead to the development of childhood overweight or obesity. Childhood obesity is a multifaceted epidemic, and is highly prevalent in low-income populations. This analysis focuses on the weight outcomes of babies at 12 months of age who are from low-income, Mexican American families. The weight and BMI of the mother, basic feeding practices, and acculturation were some of the factors that were found to have correlations with the weight of a child at 12 months. The HOME Scale was used in this data analysis, however, no significant correlations can be found at this time. Further research with children who are older than 1-year-old should be performed to determine if the HOME Inventory factors play a role in the weight outcome of a child.

Description
The purpose of this study was to determine if there were asymmetries in ground reaction forces (GRF) between dancers and non-dancers, and to see the effect of GRF on external (ER) and internal rotator (IR) strength. Subjects performed double- and single-legged jumps on a force plate with a motion capture marker system attached at anatomical landmarks, and then had strength and range of motion (ROM) of their internal and external rotators tested along at degrees of hip flexion. There were no significant differences in GRF between legs for all subjects involved. However, stronger hip ER was negatively correlated with vertical GRF (z-axis), positively correlated with anteroposterior (y-axis) GRF, and higher mediolateral (x-axis) GRF from double-leg trials was positively correlated with knee abduction. Thus, future studies should further investigate GRF broken into axial components as well as the time to peak GRF to determine any relation of these factors to knee valgus and ACL injury risk.
