Factors associated with changes in physical activity levels among Chinese international students in South Korea.

Purpose: Physical activity is widely recognized for its physical and mental health benefits that are significant for international students who often encounter environmental and cultural challenges. This study aimed to assess the physical activity levels and changes among Chinese international students in South Korea and identify the factors associated with these changes.

Methods: The study included 192 Chinese students from a single university, recruited via an anonymous survey link on WeChat that collected data on sociodemographics, health behaviors, acculturative stress, depression, and social support. Physical activity levels were assessed using the Global Physical Activity Questionnaire and changes in physical activity in South Korea were also evaluated. Multivariate multinomial logistic regression analysis was used to identify factors associated with decreased and increased physical activity among the students.

Results: Among the participants, 33.9% indicated decreased physical activity, whereas 29.7% reported increased physical activity compared with their home country. Barriers include academic stress, time constraints, and unfamiliar environments, whereas facilitators include exercise facility accessibility and support from others. Increased physical activity was positively associated with older age, weight changes, and recreational activities. Poor self-health perception was positively associated with reduced physical activity, whereas perceived discrimination and transportation-related physical activity were negatively associated with reduced physical activity.

Conclusion: Changes in physical activity levels and their associated factors among Chinese international students in South Korea were revealed. Multidimensional factors must be addressed to improve physical activity levels, especially considering the challenging circumstances faced by international students.
