2020 WHO guidelines on physical activity and sedentary behaviour for children and adolescents aged 5–17 years: Summary of the evidence
(Peer reviewed; Journal article, 2020)Background: The World Health Organization (WHO) released in 2020 updated global guidelines on physical activity and sedentary behaviour for children, adolescents, adults, older adults and sub-populations such as pregnant ... -
Accelerometer-measured physical activity and sedentary time in a cohort of US adults followed for up to 13 years: The influence of removing early follow-up on associations with mortality
(Peer reviewed; Journal article, 2020)Background: Observational studies linking physical activity with mortality are susceptible to reverse causation bias from undiagnosed and prevalent diseases. Researchers often attempt to deal with reverse causation bias ... -
Associations of lipoprotein particle profile and objectively measured physical activity and sedentary time in schoolchildren: A prospective cohort study
(Peer reviewed; Journal article, 2022)Background: Our understanding of the mechanisms through which physical activity might benefit lipoprotein metabolism is inadequate. Here we characterise the continuous associations between physical activity of different ... -
Children's moderate-to-vigorous physical activity on weekdays versus weekend days: A multi-country analysis
(Peer reviewed; Journal article, 2021)Purpose: The Structured Days Hypothesis (SDH) posits that children’s behaviors associated with obesity – such as physical activity – are more favorable on days that contain more ‘structure’ (i.e., a pre-planned, segmented, ... -
A closer look at the relationship among accelerometer-based physical activity metrics: ICAD pooled data
(Peer reviewed; Journal article, 2019)Background: Accelerometers are widely used to assess child physical activity (PA) levels. Using the accelerometer data, several PA metrics can be estimated. Knowledge about the relationships between these different metrics ... -
Contributions of changes in physical activity, sedentary time, diet and body weight to changes in cardiometabolic risk
(Peer reviewed; Journal article, 2021)Background: Increased physical activity (PA), reduced time spent sedentary (SED), healthier diet and reduced body weight may all have a positive impact on cardiometabolic risk. The relative importance of change in each of ... -
Cross-sectional and longitudinal associations of active travel, organised sport and physical education with accelerometer-assessed moderate-to-vigorous physical activity in young people: The International Children’s Accelerometry Database
(Peer reviewed; Journal article, 2022)Background: Physical activity (PA) declines during childhood. Important sources of PA are active travel, organised sport and physical education (PE), but it is unclear how these domain-specific PA sources contribute to ... -
The effect of a school-based intervention on physical activity, cardiorespiratory fitness and muscle strength: The School in Motion cluster randomized trial
(Peer reviewed; Journal article, 2020)Background: Physical activity (PA) declines throughout adolescence, therefore PA promotion during this period is important. We analyzed the effect of two school-based PA interventions on daily PA levels, cardiorespiratory ... -
Five-year cost-effectiveness analysis of the European Fans in Training (EuroFIT) physical activity intervention for men versus no intervention
(Peer reviewed; Journal article, 2020)Objectives: Increasing physical activity reduces the risk of chronic illness including Type 2 diabetes, cardiovascular disease and certain types of cancer. Lifestyle interventions can increase physical activity but few ... -
Longitudinal change in physical activity and adiposity in the transition from adolescence to early adulthood: The 1993 Pelotas cohort study
(Peer reviewed; Journal article, 2022)Background: In the current Physical Activity Guidelines (PAG) for moderate- and vigorous-intensity physical activity (MVPA), abrupt transition from ≥ 60 min/day [youth PAG] to ≥ 150 min/week (≥ 22 min/day on average) [adult ... -
Measuring change in trials of physical activity interventions: A comparison of self-report questionnaire and accelerometry within the PACE-UP trial 11 Medical and Health Sciences 1117 Public Health and Health Services
(Peer reviewed; Journal article, 2019)Background: Few trials have compared estimates of change in physical activity (PA) levels using self-reported and objective PA measures when evaluating trial outcomes. The PACE-UP trial offered the opportunity to assess ... -
Multicollinear physical activity accelerometry data and associations to cardiometabolic health: Challenges, pitfalls, and potential solutions
(Peer reviewed; Journal article, 2019)Background: The analysis of associations between accelerometer-derived physical activity (PA) intensities and cardiometabolic health is a major challenge due to multicollinearity between the explanatory variables. This ... -
New global guidelines on sedentary behaviour and health for adults: Broadening the behavioural targets
(Peer reviewed; Journal article, 2020)Background: In 2018, the World Health Organisation (WHO) commenced a program of work to update the 2010 Global Recommendations on Physical Activity for Health, for the first-time providing population-based guidelines on ... -
Reference values for wrist-worn accelerometer physical activity metrics in England children and adolescents
(Peer reviewed; Journal article, 2023)Background: Over the last decade use of raw acceleration metrics to assess physical activity has increased. Metrics such as Euclidean Norm Minus One (ENMO), and Mean Amplitude Deviation (MAD) can be used to generate metrics ... -
Substituting prolonged sedentary time and cardiovascular risk in children and youth: a meta-analysis within the International Children’s Accelerometry database (ICAD)
(Peer reviewed; Journal article, 2019)Background: Evidence on the association between sitting for extended periods (i.e. prolonged sedentary time (PST)) and cardio-metabolic health is inconsistent in children. We aimed to estimate the differences in cardiometabolic ... -
Systematic review of the prospective association of daily step counts with risk of mortality, cardiovascular disease, and dysglycemia
(Peer reviewed; Journal article, 2020)Background: Daily step counts is an intuitive metric that has demonstrated success in motivating physical activity in adults and may hold potential for future public health physical activity recommendations. This review ... -
Temporal trends in physical activity levels across more than a decade – a national physical activity surveillance system among Norwegian children and adolescents
(Peer reviewed; Journal article, 2021)Background: There is a scarcity of device measured data on temporal changes in physical activity (PA) in large population-based samples. The purpose of this study is to describe gender and age-group specific temporal trends ... -
The multivariate physical activity signature associated with metabolic health in children
(Journal article; Peer reviewed, 2018)Background: Physical activity is a cornerstone for promoting good metabolic health in children, but it is heavily debated which intensities (including sedentary time) are most influential. A fundamental limitation to current ... -
