The associations among racial discrimination, pubertal timing, neighborhoods, and mental health among U.S. Mexican boys.

The present study addressed gaps in puberty and weathering research by examining the relation between peer racial discrimination, pubertal timing, internalizing and externalizing symptoms, and neighborhood context among a longitudinal sample of U.S. Mexican boys. Using three waves of data (N = 383; mean ages: 10.3-15.8 years), we examined the weathering hypothesis: Whether peer racial discrimination experiences in late childhood predicted earlier pubertal timing in adolescence and subsequent mental health problems. We also examined whether variability in youths' neighborhood contexts qualified these associations. Consistent with the weathering hypothesis, exposure to peer racial discrimination in 5th grade, predicated earlier pubertal timing in the 7th grade, which, in turn, predicted increases in internalizing symptoms in the 10th grade. However, this pattern only applied to boys residing in neighborhoods with higher levels of Latinx concentration in 5th grade. Additionally, early timing in the 7th grade predicted increases in externalizing symptoms, but this association was significant only when boys lived in neighborhoods that were lower on Latinx concentration. There was evidence of weathering in context with specific implications for internalizing symptoms, and that neighborhood Latinx concentration was both inhibiting and promoting at unique places in the hypothesized model. The findings advance existing understandings of weathering patterns and individual variation in pubertal timing among U.S. Mexican boys. (PsycInfo Database Record (c) 2022 APA, all rights reserved).

A prospective examination of neighborhood social and cultural cohesion and parenting processes on ethnic-racial identity among U.S. Mexican adolescents.

Neighborhood social processes may have important implications for parenting processes and ethnic-racial identity (ERI) processes and content in adolescence. Past research suggests that adolescents whose parents engaged in more cultural socialization, an important aspect of parental racial socialization, had higher levels of ERI processes and content. Parenting, however, is also situated within neighborhood contexts and can be influenced by resources available in neighborhoods. For example, having neighbors who share mutual values, trust one another, and appreciate/celebrate one's heritage culture may be a resource that promotes parents' efforts to engage in cultural socialization. We prospectively examined (from x¯age = 10.9-15.8 years) a model in which U.S. Mexican parents' perceptions of neighborhood social and cultural cohesion supported parents' engagement in higher levels of cultural socialization and in turn promoted adolescents' ethnic-racial identity processes and content. We tested a longitudinal mediation model with a sample of 749 U.S. Mexican adolescents (30% Mexico born; 48.9% female) and their parents. Mother-adolescent models suggest mothers' perception of neighborhood social and cultural cohesion in late childhood promoted middle adolescents' ERI affirmation via intermediate increases in maternal cultural socialization. Similar patterns were observed for ERI resolution, but only for adolescents whose mothers were born in the United States. We did not find evidence for mediation in the father-adolescent models. Findings are discussed in the context of the promoting nature of socially and culturally supportive neighborhood environments for U.S. Mexican families and adolescents.
