Abstract:
Problem statement: The factors that related to sleep quality are diverse. A body of studies examined physical activity and stress, life satisfaction and sleep quality, but to date no studies investigated the association amongst them regarding the age. Little is known about the difference of stress, life satisfaction and sleep quality between physically active and non-active people. Approach: A cross-sectional study was launched with 292 participants, who answered a battery of questionnaires formulated by Qualtrics online research platform. Purpose: The aim of this study was to present the relationship between demographic factor (e.g. gender, age) with physical activity, life satisfaction, stress and sleep quality. Results: The prevalence of moderate (69.9%) stress was the highest compared with those reporting low (24.7%) and high (5.5%) stress. Stress and life satisfaction were significantly correlated with sleep quality (p < .05), but only stress associated significantly with sleep quality (p<.00, SE=.03, B=.43). In addition, there was no significant relationship between sleep quality and physical activity. Sedentary lifestyle is not beneficial for life satisfaction, and people who carry on sedentary lifestyle is more easily to get stressed. Conclusion: It is suggested to take into consideration about age when discussing the mechanism between physical activity and sleep quality. The effect of physical activity on sleep quality among healthy population needs more evidence. Future studies are suggested to classify the substantial benefits of specific physical activity types on stress and sleep quality.
