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 ... -
A systematic review of reliability and objective criterion-related validity of physical activity questionnaires
(Journal article; Peer reviewed, 2012-08-31)Physical inactivity is one of the four leading risk factors for global mortality. Accurate measurement of physical activity (PA) and in particular by physical activity questionnaires (PAQs) remains a challenge. The aim of ... -
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 ... -
Are screen-based sedentary behaviors longitudinally associated with dietary behaviors and leisure-time physical activity in the transition into adolescence?
(Journal article; Peer reviewed, 2013-01-25)Background: There is a need for more longitudinal studies investigating the associations between screen-based sedentary behaviors (SB), dietary behaviors and leisure-time physical activity (PA). Methods: In the HEIA ... -
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 ... -
Changes in adolescents’ intake of sugarsweetened beverages and sedentary behaviour: results at 8 month mid-way assessment of the HEIA study - a comprehensive, multi-component school-based randomized trial
(Journal article; Peer reviewed, 2011-06-17)Background: Inconsistent effects of school-based obesity prevention interventions may be related to how different subgroups receive them. The aim of this study was to evaluate the effect of an intervention program, ... -
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 ... -
Combined influence of epoch length, cut-point and bout duration on accelerometry-derived physical activity
(Journal article; Peer reviewed, 2014-03-10)Background: It is difficult to compare accelerometer-derived estimates of moderate-to-vigorous physical activity (MVPA) between studies due to differences in data processing procedures. We aimed to evaluate the effects of ... -
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 analysis of the association between mode of school transportation and physical fitness in children and adolescents
(Journal article; Peer reviewed, 2013-07-17)Objective: To investigate the associations between body composition, cardiorespiratory and muscular fitness in relation to travel mode to school in children and adolescents. Method: Children and adolescents from 40 ... -
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 ... -
Developing a systems-based framework of the factors influencing dietary and physical activity behaviours in ethnic minority populations living in Europe - a DEDIPAC study
(Journal article; Peer reviewed, 2017)Background: Some ethnic minority populations have a higher risk of non-communicable diseases than the majority European population. Diet and physical activity behaviours contribute to this risk, shaped by a system of ... -
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 ... -
Harmonising data on the correlates of physical activity and sedentary behaviour in young people: Methods and lessons learnt from the international Children's Accelerometry database (ICAD)
(Peer reviewed; Journal article, 2017)Background: Large, heterogeneous datasets are required to enhance understanding of the multi-level influences on children’s physical activity and sedentary behaviour. One route to achieving this is through the pooling and ... -
Levels and patterns of objectively-measured physical activity volume and intensity distribution in UK adolescents: the ROOTS study
(Journal article; Peer reviewed, 2014-02-24)Background: Few studies have quantified levels of habitual physical activity across the entire intensity range. We aimed to describe variability in total and intensity-specific physical activity levels in UK adolescents ... -
Levels of physical activity among a nationally representative sample of people in early old age: results of objective and self-reported assessments
(Journal article; Peer reviewed, 2014-05-03)Detailed assessment of physical activity (PA) in older adults is required to comprehensively describe habitual PA-levels in this growing population segment. Current evidence of population PA-levels is predominantly based ... -
