Description
Obesity in Hispanic youth has reached alarmingly high levels, increasing the risk of type 2 diabetes, hyperlipidemia, hypertension, and cardiovascular disease. In Mexican American children ages 6-11 years, 41.7% are overweight and obese, 24.7% are obese and 19.6% have a Body Mass Index (BMI) greater than the 97th percentile. While personal, behavioral, and environmental factors contribute to these high rates, emerging literature suggests acculturation, self-efficacy and social support are key influences. The one-group, pre- and post-test, quasi-experimental design used a community-based participatory research (CBPR) method to test the feasibility, acceptability, and preliminary efficacy of the 8-week intervention. Social Cognitive Theory (SCT) was used to guide the design. Measurements included an analysis of recruitment, retention, participant satisfaction, observation of intervention sessions, paired t-tests, effect sizes, and bivariate correlations between study variables (acculturation, nutrition and physical activity [PA] knowledge, attitude and behaviors, perceived confidence and social support) and outcome variables (BMI z-score, waist circumference and BP percentile) Findings showed the SSLN program was feasible and acceptable. Participants (n = 16) reported that the curriculum was fun and they learned about nutrition and PA. The retention rate was 94%. The preliminary effects on adolescent nutrition and PA behaviors showed mixed results with small-to-medium effect sizes for nutrition knowledge and attitude, PA and sedentary behavior. Correlation analysis among acculturation and study variables was not significant. Positive associations were found between perceived confidence in eating and nutrition attitude (r = .61, p < .05) and nutrition behavior (r = .62, p < .05), perceived confidence in exercise and nutrition behavior (r = .66, p < .05), social support from family for exercise and PA behavior (r = .67, p < .01) and social support from friends for exercise and PA behavior (r = .56, p < .05). These findings suggest a culturally specific healthy eating and activity program for adolescents was feasible and acceptable and warrants further investigation, since it may fill a gap in existing obesity programs designed for Hispanic youth. The positive correlations suggest further testing of the theoretical model.

Description
Human Immunodeficiency Virus (HIV) remains a persistent problem around the world, even though antiretroviral therapy has shown to be effective in reducing viral load and limiting transmission of the virus. Due to HIV’s infectious nature, visibility, the populations at risk, and its connections to race, class, and sexuality, it is more stigmatized than any other illness. HIV stigma has been associated with increased depression, social isolation, and poor psychological adjustment. HIV stigma can influence disclosure and care-seeking behavior. Internet-based interventions have shown to be effective in increasing knowledge on STIs and HIV, however, researchers have tested strategies that include educating participants on HIV to reduce stigma and have found that informational approaches alone are not effective. There is evidence that emotional intelligence and empathy are associated with prosocial behavior and influence attitudes towards stigmatized groups. Thus, this thesis aims to test an online intervention using an informational video from the Center for Disease Control and Prevention (CDC) in combination with an empathy-generating component to reduce stigma. It was hypothesized that the online intervention would increase HIV knowledge scores (H1), but stigma will only be reduced in the group introduced to the empathy-inducing component (H2) and those with high emotional intelligence would show the greatest reduction in stigmatizing attitudes (H3). Results did not support these hypotheses, suggesting that the CDC’s video does not significantly increase HIV knowledge in the general public. Further, the video intended to generate empathy and reduce stigma was also ineffective. These findings stress the need for further research and questions the effectiveness of empathy-generating interventions (e.g., FACES OF HIV, HIV Justice Network) to increase knowledge and reduce stigma. Future researchers should test the effectiveness of personalized interventions to reduce HIV-related stigma.
