BACKGROUND: E-cigarette use has been linked with multiple morbidities and changes in health behavior. This study investigates e-cigarette use with sleep patterns, stress levels, and physical activity behavior and compare it with nonsmokers. METHODS: A standardized electronic questionnaire for sleep, stress, and physical activity assessment was used on 372 students enrolled in a large university. Statistical analysis was performed using Statistical Package for the Social Sciences (SPSS) version 23.0. RESULTS: The mean age of the study population was around 20 years, with e-cigarette use higher in males. The mean age of smoking initiation was 17 years. The intention to play sports and physical activity differed between smokers and nonsmokers. E-cigarette users practiced sports to remain fit while nonsmokers intended to play sports for enjoyment
however, no significant difference in the level of fitness was found. Sleep behavior and stress levels were similar across the two groups. CONCLUSION: No difference in lifestyle patterns between e-cigarette users and nonsmokers may be due to lesser smoking duration since initiation. Longitudinal studies with diverse populations and a longer duration of e-cigarette use are recommended to explore the effects of e-cigarette smoking on lifestyle behavior.
