Digital Technology, Sedentary Behaviour and Physical Activity Among University Students in Nigeria: Implications for Health Education

Background: Digital technology has become central to university education in Nigeria, with smartphones, laptops, online learning platforms, electronic libraries and social media increasingly integrated into students' academic and social lives. However, many digital activities are performed while sitting, potentially contributing to prolonged sedentary behaviour and reduced opportunities for physical activity.Objective: This narrative review examines the relationship between digital technology use, sedentary behaviour and physical activity among university students in Nigeria and considers implications for health education.Methods: Recent Nigerian studies and relevant international literature were reviewed, with attention to physical activity, sedentary behaviour, screen time, smartphone use, sleep, mental health and ergonomic health. World Health Organization guidance on physical activity and sedentary behaviour was also considered.Findings: Available Nigerian evidence indicates challenges in achieving healthy combinations of physical activity, recreational screen time and sleep among university students. Studies have also examined smartphone use, sedentary behaviour, ergonomic posture and neck-related health outcomes. International evidence suggests that physical-activity interventions may improve aspects of university students' mental health, although methodological differences and heterogeneity remain.Conclusion: Universities can support healthier digital lifestyles by promoting physical activity, reducing prolonged uninterrupted sitting, encouraging movement breaks, improving ergonomic awareness, supporting healthy sleep and creating environments that make physical activity accessible to students. Further Nigerian research using larger samples, objective measures and longitudinal or intervention designs is recommended.
