Description
This ethnographic study contributes to the literature on Latin@ youth in the US by focusing on the experiences of Latin@ youth in Arizona and their identity management practices. The data from 9 months of field observations and 11 unstructured interviews provides a vivid picture of the youth's daily encounters. Using a thematic analysis this study reveals the youth's experiences in occupying predominantly white spaces, managing privilege, and managing negative stereotypes. The youth's involvement at El Centro, an Arizona nonprofit organization, provided them a safe space in which they created a familial environment for themselves and their peers.

Description
The present study explored longitudinal associations between self-esteem and a specific dimension of gender identity (GI) and ethnic-racial identity (ERI), namely felt pressure from family and peers to act or behave in either gender or race/ethnic-accordant ways, among a sample of 750 African American and Latino/a middle school students (M = 12.10 years, SD = .97 years) in a southwestern U.S. city. Participants completed measures of self-esteem and GI and ERI felt pressure from family and from peers at two time points. Data were analyzed through bivariate correlation and hierarchical multiple linear regression analyses. Hierarchical multiple linear regression results revealed that among African American students, there was a significant negative longitudinal association between ERI felt pressure from family at Time 1 and self-esteem at Time 2 after controlling for self-esteem at Time 1. There was also a significant negative longitudinal association between ERI felt pressure from peers at Time 1 and self-esteem at Time 2 among African American participants. However, these associations were not found among Latino/a participants. Implications of findings with regards to GI and ERI development during early adolescence, socialization, and school context are discussed.

Description
Latino youth have substantially higher rates of obesity and T2D than their white peers. The higher prevalence of obesity and T2D among Latino youth places them at greater risk for cognitive dysfunction, an urgent and serious health threat to the United States. Exercise has been the cornerstone to combat the negative effects of obesity, diabetes and recent research also supports this effects for preventing cognitive dysfunction. A wealth of evidence suggests that a mediating mechanism linking exercise with brain health is BDNF, a cognitive biomarker that increases in the brain with exercise. BDNF is the most abundant neurotrophic factor that supports growth, survival and synaptic plasticity of neurons, all vital for cognitive function and brain health. The present study sought to investigate the effects of a 12-week lifestyle intervention of physical activity and lifestyle education on serum BDNF, in obese pre diabetic Latino youth.
A total of twelve obese pre diabetic Latino youth were selected from a larger RCT sample to be the focus for this analysis. After an overnight fast, a serum concentration was collected from all youth to be used for the BDNF analysis. In addition, the following cardio metabolic measures were also at taken at baseline and post intervention: Submaximal VO2max, medical and family history questionnaire, anthropometric, fasting glucose and a 2-hour oral glucose tolerance test (OGTT). A 12-weeks Lifestyle Intervention that involved a progressive moderate to high intensity exercise component and lifestyle education program did not significantly change serum BDNF levels in obese pre diabetic Latino youth. In conclusion, the variation of our serum BDNF results are highly speculative at this time, therefore the need for future investigations is crucial.
