The 7 subcomponents of the PSQI were calculated and represent: (1) subjective sleep quality, (2) sleep latency, (3) sleep duration, (4) sleep efficiency, (5) sleep disturbances, (6) use of sleep medication, and (7) daytime

The purpose of this study was to examine the effects of fundamental movement skills (FMS) training on FMS proficiency, self-perceived physical competence (SPC), physical activity (PA), and sleep disturbance in children with developmental coordination disorder (DCD) compared with children with typical development (TD). A total of 84 children were allocated into either experimental group (DCD[exp], TD[exp]) who received 6 weeks of FMS training or control groups (DCD[con], TD[con]). FMS were assessed using the Test of Gross Motor Development-2, whereas PA was monitored using accelerometers. SPC and sleep disturbance were evaluated using questionnaires. Results showed that the DCD[exp] group had significantly higher scores in FMS and SPC compared with the DCD[con] group at posttest. The DCD[exp] group scored lower in sleep disturbance at follow-up when compared with posttest. It is suggested that short-term FMS training is effective in improving FMS and SPC and reducing sleep disturbances for children with DCD.

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.
