ABSTRACT Objective: The use of social-networking services (SNSs) is increasing among young Japanese people. Previous studies showed that psychological stress via SNS has increased in Japanese undergraduate students, including physical therapy students. However, little is known about the impact of SNS usage on self-learning activity (self-LA) and physical activity (PA) in Japanese undergraduate physical therapy students. In this study, we aimed at clarifying the association between them using a single-university cross-sectional study. Methods: A total of 113 second- to fourth-year undergraduate physical therapy students (aged 19–22 years) volunteered for this study. Using selfadministered questionnaires, the participants answered questions regarding SNS usage, such as the purpose of SNS usage (e.g., communicating with friends, selfpromotion, collecting information, building friendship), self-LA, and PA, including vigorous-intensity PA (VPA), moderate-intensity PA (MPA), walking, moderate- to vigorous-intensity PA (MVPA), and sitting. Results: Data of 84 participants (65 men and 19 women) were analyzed. Stepwise multiple regression analysis after adjusting for gender showed that self-LA did not change by other variables, VPA decreased in the upper year, MPA was lower in the participants who had the purpose of “self-promotion” through SNS than in those who did not, walking and MVPA decreased in the upper year and were higher in the participants who had the purpose of “building friendship” through SNS than in those who did not. There was no association between sitting and SNS usage. Conclusion: We found that SNS usage had no impact on self-LA; however, it had both a negative and positive impact on PA among participants. Proper assessment and management of SNS usage may be important to increase PA among Japanese undergraduate physical therapy students.
