Background Anxiety disorders are among the most prevalent psychological disorders experienced during adolescence. Studies have suggested that physical activity may contribute to a beneficial role for anxiety including the prevention and reduction of anxiety symptoms among adolescents. This systematic review aims to explore the possible relationship between physical activity and anxiety. Methods A systematic search was performed to locate randomized-controlled trials (RCT)from 1980to 30 April 2014 in PubMed, MEDLINE(ProQuest), PsycINFO(ProQuest) and Google scholar. Quality of RCTs was assessed using JADAD. The relationship of physical activity and anxiety was explored. The change of anxiety reported scores for intervention groups in the follow-up period was tabulated. Findings From the results of five studies, physical activity may change mean anxiety scores in the general population of adolescents respectively. Regarding the within intervention group analysis, five studies had showed the significant changes compared pre-test and post-test anxiety scores, which support the positive effects of physical activity on anxiety. But no more evidence showed the specific period and depth the effects of interventions group as seldom trials reported follow-up data. That meant, we couldn’t tell whether there was enduring impacts of physical activity on reduction of anxiety symptoms. In these studies, the evidence of improvement levels of physical activity was weak as there were no consistent criteria of vigorous and aerobic exercise. Conclusion The reduction of anxiety scores with physical activity intervention is the main findings. Though most results showed significant improvement, limitations in the study design, analysis and reporting limit the inferences regarding the effect of physical activity on the reduction and prevention of anxiety. / published_or_final_version / Public Health / Master / Master of Public Health

This study examined the relationship between anxiety, social stress, and gambling behavior among 1,044 high school students from grades 7 to 11. Adolescents completed questionnaires concerning their state, trait, and generalized anxiety, social stress, and gambling behavior. Results reveal that probable pathological gamblers report more state anxiety, trait anxiety, and social stress compared to non-gamblers, gamblers with no/minimal problems, and problem gamblers. Gamblers with the highest levels of state and trait anxiety engaged in more severe gambling behaviors, substance abuse, reported different reasons for gambling, and endorsed more dissociation items compared to gamblers whose anxiety and social stress levels were in the average or low range. Results of this study provide added support for Jacob's General Theory of Addictions.

This study tested a structural model, examining the relationship between a latent variable termed demoralization and measured variables (anxiety, depression and hopelessness) in a community sample of Canadian youth. The combined sample consisted of data collected from four independent studies from 2001 to 2005. Nine hundred and seventy one (n=971) participants in each of the previous four studies were high school students (grades 10-12) from three geographic locations: Calgary, Saskatchewan and Lethbridge. Participants completed a battery of self-report questionnaires including the Beck Anxiety Inventory (BAI), Beck Depression Inventory-Revised (BDI-II), Beck Hopelessness Scale (BHS), and demographic survey. Structural equation modeling was used for statistical analysis. The analysis revealed that the final model, including depression, anxiety and hopelessness and one latent variable demoralization, fit the data (chi-square value, X2 (2) =7.24, p<. 001, goodness of fit indices (CFI=0.99, NFI=0.98) and standardized error (0.05). Overall, the findings suggest that close relationships exist among depression, anxiety, hopelessness and demoralization. In addition, the model was stable across demographic variables: sex, grade, and location. Further, the model explains the relationship between sub-clinical anxiety, depression and hopelessness. These findings contribute to a theoretical framework, which has implications with educational and clinical interventions. The present findings will help guide further preventative research in examining demoralization as a precursor to sub-clinical anxiety and depression. / xi, 127 leaves ; 29 cm.
