The time spent by adolescents in electronic screen-based activities has been associated with obesity and other adverse health outcomes; however, little is known about screen-based behaviors in Asian adolescents. The purpose of this study was to describe the prevalence, patterns, and correlates of recreational screen-based behaviors among adolescents in Bangladesh.
A total of 758 students (52% girls), aged 13 to 16 years, from 8 secondary schools of Dhaka city, Bangladesh, completed a survey in which the Adolescent Sedentary Activity Questionnaire was used to collect information on screen time. Total screen time was categorized as ≤2 h/day (low) or >2 h/day (high).
Approximately 79% of the adolescents had high recreational screen time, with similar values for boys (78%) and girls (80%). Median reported recreational screen time was 4.0 h/day; boys had longer times (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 was positively associated with commuting to school by car, consumption of fast food ≥3 times/week, having sleep disturbance, and high family income.
This study identified high rates of recreational screen time among urban adolescents in Bangladesh and specific correlates of prolonged screen time; the results underscore the need to develop pragmatic strategies to reduce sedentariness among adolescents in Bangladesh.
青少年花在电子屏幕活动上的时间与肥胖及其他不良健康后果有关;然而,对于亚洲青少年基于屏幕的行为知之甚少。本研究的目的是描述孟加拉国青少年娱乐性屏幕行为的患病率、模式及相关因素。
来自孟加拉国达卡市8所中学的758名学生(52%为女生),年龄在13至16岁之间,完成了一项调查,其中使用青少年久坐活动问卷收集屏幕时间信息。总屏幕时间分为≤2小时/天(低)或>2小时/天(高)。
约79%的青少年娱乐性屏幕时间高,男孩(78%)和女孩(80%)的数值相似。报告的娱乐性屏幕时间中位数为4.0小时/天;男孩的时间(4.3小时/天)比女孩(3.6小时/天)长。多变量分析显示,高屏幕时间在男孩中比女孩更常见,且与乘汽车上学、每周食用快餐≥3次、有睡眠障碍和高家庭收入呈正相关。
本研究确定了孟加拉国城市青少年娱乐性屏幕时间的高发生率以及屏幕时间延长的特定相关因素;结果强调需要制定务实策略以减少孟加拉国青少年的久坐行为。
