To examine a potential association between biologically confirmed secondhand smoke exposure and symptoms of Diagnostic and Statistical Manual of Mental Disorders (Fourth Edition) (DSM-IV) major depressive disorder, generalized anxiety disorder, panic disorder, attention-deficit/hyperactivity disorder, and conduct disorder using a nationally representative sample of US children and adolescents.Design: Nationally representative cross-sectional survey of the United States.

Purpose The current study was conducted to ascertain whether the effects of nativity (i.e., U.S. born vs. immigrant) on Hispanic adolescent substance use is mediated by ecological processes such as family functioning, school connectedness, and perceived peer substance use. Methods The effects of family, peer, and school processes on adolescent substance use were examined in a nationally representative sample of 742 (358 male, 384 female) Hispanic youth (mean age = 15.9; SD = 1.8). Results Results from a structural equation model indicated that the higher rates of substance use among U.S.-born Hispanics (compared with foreign-born Hispanics) are partially mediated by perceived peer substance use (as measured by the adolescent). The results also showed that perceived peer substance use and school connectedness mediate the relationship between family processes and substance use, suggesting that family processes may offset some of the deleterious effects of negative peer selection on adolescent substance use. Conclusion These findings imply that public health behavioral interventions to prevent substance use among both U.S.-born and foreign-born Hispanics may need to attend to multiple ecological processes, including family, school, and peers.

Ecodevelopmental theory is a theoretical framework used to explain the interplay among risk and protective processes associated with HIV risk behaviors among adolescents. Although ecodevelopmentally based interventions have been found to be efficacious in preventing HIV risk behaviors among Hispanic youth, this theory has not yet been directly empirically tested through a basic research study in this population. The purpose of this cross-sectional study was to empirically evaluate an ecodevelopmentally based model using structural equation modeling, with substance use and early sex initiation as the two outcomes of the ecodevelopmental chain of relationships. The sample consisted of 586 Hispanic youth (M age = 13.6; SD = 0.75) and their primary caregivers living in Miami, Florida. Adolescent, parent, and teacher reports were used. The results provided strong support for the theoretical model. More specifically, the parent–adolescent acculturation gap is indirectly related both to early sex initiation and to adolescent substance use through family functioning, academic functioning, perceived peer sexual behavior, and perceived peer substance use. Additionally, parent’s U.S. orientation is associated with adolescent substance use and adolescent sex initiation through social support for parents, parental stressors, family functioning, academic functioning, and perceived peer sexual behavior and substance use. These findings suggest that HIV risk behaviors may best be understood as associated with multiple and interrelated ecological determinants.

Objective-To evaluate the association between secondhand smoke (SHS) exposure and depression. Tobacco smoking and depression are strongly associated, but the possible effects of SHS have not been evaluated. Results-Serum cotinine-documented SHS exposure was positively associated with depressive symptoms in never-smokers, even after adjustment for age, race/ethnicity, gender, education, alcohol consumption, and medical comorbidities. The association between SHS exposure and depressive symptoms did not vary by gender, nor was there any association between SHS smoke exposure and depressive symptoms in former smokers. Methods-TheConclusions-Findings from the present study suggest that SHS exposure is positively associated with depressive symptoms in never-smokers and highlight the need for further research to establish the mechanisms of association.
