Background: Screen-time of adolescents has been associated with obesity and other adverse health outcomes; however, little is known about screen-based behaviours in Asian adolescents. The purpose of this study was to describe the prevalence, patterns and correlates of recreational screen-based behaviours among adolescents in Bangladesh.
Methods: A total of 758 students, aged 13-16 years and 52% girls, from eight secondary schools of Dhaka city, Bangladesh completed a survey where the Adolescent Sedentary Activity Questionnaire was used to collect information on screen-time. Total screen-time was categorised as ≤2 h/day (low) or >2 h/day (high).
Results: About 79% of the adolescents had high recreational screen-time, with similar proportions between boys (78%) and girls (80%). Median reported recreational screen-time was 4.0 h/day with longer times among boys (4.3 h/day) than girls (3.6 h/day). Multivariable analyses showed that high screen-time was more common among boys than girls, and positively associated with commuting to school by car, consumption of fast food >3 times/week, having sleep disturbance, and high family income.
Conclusions: This study identified high rates of recreational screen-time among urban adolescents in Bangladesh and specific correlates of prolonged screen-time, and underscores the needs for developing pragmatic strategies to reduce sedentariness among adolescents in Bangladesh.
