Objective: The aim of this study was to determine the effect of the COVID-19 pandemic on stress levels and sleep patterns. Methods: This was a cross sectional study that involved a hundred medical students of Universitas Sumatera Utara. The data of this study was obtained by questionnaires and analyzed using Spearman correlation test. Results: This study found that based on the stress level, there were 59 students categorized normal, mild 16 students, moderate 10 students, severe 9 students, and very severe 6 students. The sleep patterns described that only 11 students slept normally and 89 students experienced sleep disturbances during the COVID-19 pandemic. This study found there was a significant correlation between the COVID-19 pandemic on stress levels (p:0.01 and r:0.58) and sleep patterns (p:0.01 and r:0.36). Conclusion: This study found that the COVID-19 pandemic had a significant impact on increasing stress levels and causing sleep disturbances among medical students. Strengthening mental health support during pandemics is essential to minimize these effects.

Abstract

Introduction: Physical activity contributes to mental well-being by stimulating neurotransmitters associated with pleasure and positive mood. Understanding this relationship within specific populations is important for promoting community health. Objective: This study aimed to evaluate the correlation between physical activity and happiness among residents of Medan, Indonesia. Methods: This cross-sectional study was conducted in Medan from May to November 2021 and involved 260 participants. Physical activity was assessed using the International Physical Activity Questionnaire, while happiness and affect were measured using the Oxford Happiness Questionnaire and the Positive and Negative Affect Scale. Data were analyzed using Spearman’s rank correlation test. Results: Overall physical activity was positively correlated with happiness (r = 0.132; p = 0.034) and positive affect (r = 0.214; p = 0.001). Vigorous physical activity showed positive correlations with happiness (r = 0.185; p = 0.003) and positive affect (r = 0.244; p = 0.001). Walking was also positively correlated with happiness (r = 0.132; p = 0.034) and positive affect (r = 0.214; p = 0.001). Moderate physical activity was not correlated with happiness (r = –0.017; p > 0.05) or positive affect (r = 0.065; p > 0.05). No correlation was found between physical activity and negative affect. Conclusions: Physical activity is positively correlated with happiness among residents of Medan.
