Description
Hosein Ataei-Goujani and colleagues examined whether leisure-time exercise tracks with lower smartphone addiction in new university students. Their cross-sectional study appeared in Health Science Reports in 2026. It covered 397 first-year students at Tehran's medical university, a group where heavy phone use is common. Addiction was scored with a standard short scale, and activity was measured across work, travel, and leisure domains with a global questionnaire.
Only leisure-time activity showed a strong protective pattern: students who got enough moderate leisure exercise scored notably lower on addiction. The link followed a dose-response shape, with more activity tied to less addiction, and the gradient was steepest at the low end. Activity at work or in transport did not show the same tie. The authors suggest that promoting enjoyable leisure exercise, rather than exercise in general, may be the practical lever against phone addiction in this age group.
