University-based physical education as a structured temporal and spatial opportunity for shaping health-oriented lifestyles.

Background: Regular physical activity is widely recognized for its health benefits, including improved cardiovascular function and reduced risk of chronic diseases. However, insufficient physical activity remains prevalent among university students, many of whom fail to meet recommended guidelines. University-based physical education (PE) programs play a critical role in fostering active lifestyles and promoting health-oriented behaviors among young adults. This study aimed to examine the association between participation in PE classes and the adoption of health-oriented behaviors among Chinese college students, particularly in the 3 Methods: A cross-sectional study was conducted with 1,902 3 Results: Results showed 44.23% of students were physically inactive, 8.1% were smokers, and 61.18% had an unhealthy diet. Male students had higher rates of smoking, obesity, and unhealthy diets compared to females. Participation in PE classes was associated with lower risks of obesity, unhealthy diets, and physical inactivity. Logistic regression analyses confirmed that PE attendance was a protective factor against these unhealthy behaviors, with significant gender-based differences observed in lifestyle patterns. Conclusion: This study highlights the importance of PE in promoting healthier lifestyles among university students and underscores the need for continued access to structured PE programs throughout the undergraduate years.
