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
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
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.

Description
This thesis project investigated the linguistic competence of four brothers in an attempt to evaluate the effects that assimilation in the United States has on language loss within second generation speakers. The project employed the use of a case study and autoethnography in order to take a closer look at the concepts of assimilation, acculturation, and language loss, as well to provide a real world example of their interrelatedness. The second generation, or the heritage speakers in the family, were the focus of the study in order to provide a closer look at how the heritage language was retained within said generation. The project found that although there has historically been a push to assimilate immigrants into the American society, my brothers and I are not being assimilated as much as we are being acculturated. The project also found that although we grew up speaking Spanish at home, education in the language was essential in developing fluency in the subcategories of reading and writing, which are often neglected in the household.

Description
Salud Empoderada is a bilingual English-Spanish blog with the goals of providing pre-medical advice, exposure to careers in medicine through interviews with leaders in medicine and science, and resources to support and encourage Latino pre-medical college students at Arizona State University. This information is provided in the forms of blog posts and infographics. Salud Empoderada was created as a way to address the lack of representation of Latino medical students enrolled in U.S. medical schools and Latino physicians in the U.S. Therefore, Salud Empoderada targets Latino students in the first stage of their journeys to becoming a doctor, pre-medical students, to help inspire and guide them to pursue their dreams despite the challenges they may face, including struggles with mental health, socioeconomic status, access to Latino mentors in medicine and science, health disparities, gender, DACA status, attacks on affirmative action, and the MCAT exam. Furthermore, Salud Empoderada encompasses my trip with Barrett, The Honors College to Costa Rica to share insight on life in Costa Rica and the Indigenous tribes residing there. Sharing this experience with Latino pre-medical students may provide them further exposure to other cultures, the heterogeneity within Latin America, the importance of cultural competence in medicine and the possibilities that global health and Spanish studies offer to become well-rounded and holistic future physicians.

Description
This study identifies and examines healthcare barriers experienced by the Hispanic1 population in Phoenix, Arizona. A cross-sectional survey was used to explore these barriers for 123 members of the community, and the findings reveal that the main impediments to healthcare faced by the Hispanic population are structured by their language, immigration status, education level, and access to health insurance. The results of the survey were then analyzed to explore possible mechanisms of the origin or intensification of the barriers, as well as potential solutions such as educating future providers to be culturally competent, usage of integrated medical settings, and the advertisement and extension of Promotoras to the community.
