Effects of Physical Activity and Sleep Quality on Anxiety found in Adults [Kennesaw State University]
Background: The Anxiety and Depression Association of America claim that anxiety disorders are the most common form of mental illness in the United States. 18.1% of the population 18 years and older are reported to have been affected by anxiety. An increase in physical activity and an improvement in sleep quality have been found to be effective in the management of anxiety. This study was conducted to find correlations between anxiety, sleep quality, and physical activity.
Methods: Adults (n=24, male and female, Mage = 44 years) were recruited for the study through convenience sampling. Participants completed a series of questionnaires that evaluated their mood, exercise-leisure habits, and sleep quality. Two Pearson correlation coefficients were done to determine a correlation between the three variables.
Results: The correlation between anxiety and physical activity was statistically significant (r = -.42, p < .02, (r2=0.18), df= 21). The correlation found between and anxiety and sleep quality were also statistically significant (r = -.48, p < .02 (r2=.24), df = 22). The findings from both Pearson Correlation Coefficients indicated that there was a moderate association between anxiety, physical activity, and sleep quality.
Conclusion: The results agreed with existing research on anxiety. Participants’ low to moderate levels of anxiety were supported by their physical activity level and sleep quality. Due to the limited nature of the study, further research and replication of the study is necessary to yield results that are more representative of the general public.
