  1. Sedentary behaviour and health in adults: an overview of systematic reviews

    15/10/2020

    Our findings suggest that high levels of sedentary behaviour are unfavourably associated with cognitive function, depression, function and disability, physical activity levels, and physical health-related quality of life in adults. Our results also suggest that reducing or breaking up periods of prolonged sitting may have beneficial effects on markers of cardiometabolic risk and body composition. Although sedentary behaviour was generally associated with negative health outcomes, there may be favourable associations between computer and Internet use and cognitive function in older adults. Our findings have important public health implications and suggest that adults should avoid accumulating high levels of sedentary behaviour. Future work is needed to identify whether a dose–response relationship exists between sedentary behaviour and these health outcomes, and whether these relationships are consistent across sex, race/ethnicity, and socioeconomic status.

  2. Canadian 24-Hour Movement Guidelines for Adults aged 18-64 years and Adults aged 65 years or older: An Integration of Physical Activity, Sedentary Behaviour, and Sleep

    15/10/2020

    The Canadian 24-Hour Movement Guidelines for Adults aged 18–64 years and Adults aged 65 years or older: An Integration of Physical Activity, Sedentary Behaviour, and Sleep completes the set of 24-Hour Movement Guidelines that together provide recommendations for healthy movement behaviours for the whole day for all Canadians. The Guidelines were generated based on the best available evidence with extensive consultation and stakeholder feedback. The CP recognized that to adopt and sustain any movement behaviour in today’s environment presents very real challenges for all adults. It is hoped that the shift in focus from movement behaviours in isolation to the integration of all movement behaviours over the whole day will provide movement options for adults, treatment options for practitioners, and greater opportunities for public health promotion.

  3. Prevalence and sociodemographic factors associated with meeting the 24-hour movement guidelines in a sample of Brazilian adolescents

    28/09/2020

    Approximately 3% of the participants met the MVPA, screen-time, and sleep duration recommendations simultaneously, while this proportion was 0.2% when accelerometer data were used for MVPA and sleep duration. Adherence to the sleep duration recommendation was higher than to the screen-time or MVPA recommendations. Boys were more likely to meet the MVPA recommendations, but less likely to meet sleep duration and scree-time recommendations, and age was positively associated with adhering to the screen-time recommendation. Future policies and interventions should promote adherence to 24-hours movement behaviors in an integrated manner.

  4. Association between lifestyle behaviors and health-related quality of life in a sample of Brazilian adolescents

    22/09/2020

    This study identified that adolescents who spent more time on sports but not on non-sports physical activities had higher scores of HRQoL. The time spent in work-related screen activities was inversely associated with HRQoL score. However, this association was not observed for recreational screen time indicators (i.e., watching videos, playing videogames, or using social media). In addition, girls, adolescents who experimented with drugs in their life course, those with higher consumption of ultra-processed foods, and those who sleep insufficiently reported lower scores of HRQoL. These findings suggest that promoting sports and adequate sleep, and preventing the use of drugs and excessive workloads among adolescents may be effective strategies to improve HRQoL.

  5. Sleep and screen time are more linked with academic achievement than physical activity

    04/06/2020

    High school students who met the screen time and sleep guidelines showed better academic performance than those who did not meet any guidelines.
