Occupational physical activity and incidence and mortality of 14 cancers in 404,249 adults Open
Leisure physical activity is considered protective against several cancers, but the impact of physical activity at work remains unclear. We analyze data from over 400,000 Norwegian adults followed for a median of 27 years to examine how di…

Data Resource Profile: the Physical Activity Cohort Repository (PACe) Open
Key Features * The Physical Activity Cohort Repository (PACe) project created a searchable online database of cohort studies that have prospectively collected data on physical activity and/or sedentary behaviour (self-report and/or device-…

Advancing knowledge, maps and tools to address obesity and related socio-economic disparities in Europe: the OBCT project Open
The steady rise in overweight and obesity in Europe disproportionately affects people and communities with a lower socio-economic position (SEP). Many obesity prevention approaches exist, but these have had limited reach and unsatisfactory…
Physical activity and life expectancy: a life-table analysis Open
Objective Low physical activity (PA) levels are associated with increased mortality. Improved measurement has resulted in stronger proven associations between PA and mortality, but this has not yet translated to improved estimates of the d…
Physical activity, sedentary time and health – a narrative review with new insights Open
Physical activity and sedentary time are associated with multiple health outcomes, and benefits also extend to those living with chronic conditions. These observations are primarily based on data from studies in which self-reported data as…
Joint associations of device-measured physical activity and abdominal obesity with incident cardiovascular disease: a prospective cohort study Open
Objective To examine the joint associations between physical activity and abdominal obesity with the risk of cardiovascular disease (CVD) events. Methods We included 70 830 UK Biobank participants (mean age±SD=61.6 ± 7.9 years; 56.4% women…
Device-measured physical activity, sedentary time, and risk of all-cause mortality: an individual participant data analysis of four prospective cohort studies Open
Objectives To examine whether moderate-to-vigorous physical activity (MVPA) modifies the association between sedentary time and mortality and vice versa, and estimate the joint associations of MVPA and sedentary time on mortality risk. Met…
Leisure-time physical activity and risk of microvascular complications in individuals with type 2 diabetes: A UK Biobank study Open
OBJECTIVE We aimed to determine dose-response associations, including the minimal effective level, between leisure-time physical activity and risk of incident neuropathy, nephropathy, and retinopathy. RESEARCH DESIGN AND METHODS This cohor…
Leisure-time physical activity and risk of microvascular complications in individuals with type 2 diabetes: A UK Biobank study Open
OBJECTIVE We aimed to determine dose-response associations, including the minimal effective level, between leisure-time physical activity and risk of incident neuropathy, nephropathy, and retinopathy. RESEARCH DESIGN AND METHODS This cohor…

Accelerometer-derived physical activity and sedentary behaviors in individuals with newly diagnosed type 2 diabetes: A cross-sectional study from the Danish nationwide DD2 cohort Open
Introduction Habitual physical activity behaviors of individuals with new-onset type 2 diabetes are largely unknown. We aimed to investigate accelerometer-derived physical activity behaviors in individuals with newly diagnosed type 2 diabe…
Joint associations of physical activity and sedentary time with body mass index: A prospective study of mortality risk Open
Device‐measured physical activity and sedentary time are suggested to be more important determinants of all‐cause mortality compared to body mass index (BMI) in mainly older adults. However, the joint associations of physical activity and …
The metabolic syndrome is frequent in children and adolescents with type 1 diabetes compared to healthy controls Open
Children and adolescents with T1D have an increased risk of MetS compared to healthy controls and clinicians and caretakers should consider early prevention and health promotion strategies.
Device-measured sedentary time in Norwegian children and adolescents in the era of ubiquitous internet access: secular changes between 2005, 2011 and 2018 Open
Background Access to screen-based media has been revolutionized during the past two decades. How this has affected sedentary time (ST) accumulation in children is poorly understood. Methods This study, based on the Physical Activity among …
Device-measured physical activity, adiposity and mortality: a harmonised meta-analysis of eight prospective cohort studies Open
Background The joint associations of total and intensity-specific physical activity with obesity in relation to all-cause mortality risk are unclear. Methods We included 34 492 adults (72% women, median age 62.1 years, 2034 deaths during f…
Fitness, Fatness, and Mortality in Men and Women From the UK Biobank: Prospective Cohort Study Open
Background Cardiorespiratory fitness may moderate the association between obesity and all‐cause mortality (ie, the “fat‐but‐fit” hypothesis), but unaddressed sources of bias are a concern. Methods and Results Cardiorespiratory fitness was …
Stair climbing and mortality: a prospective cohort study from the UK Biobank Open
Background Regular stair climbing has the potential to lower the risk of premature death, but current evidence is scarce. We aimed to examine whether daily stair climbing is associated with lower risk of all‐cause, cancer, and cardiovascul…
Does Additional Physical Education Improve Exam Performance at the End of Compulsory Education? A Secondary Analysis from a Natural Experiment: The CHAMPS-Study DK Open
It remains unclear whether the provision of additional physical activity in school improves academic outcomes. We conducted a secondary analysis of the Childhood Health, Activity, and Motor Performance School Study Denmark (CHAMPS-study DK…
School-based interventions modestly increase physical activity and cardiorespiratory fitness but are least effective for youth who need them most: an individual participant pooled analysis of 20 controlled trials Open
Objectives To determine if subpopulations of students benefit equally from school-based physical activity interventions in terms of cardiorespiratory fitness and physical activity. To examine if physical activity intensity mediates improve…
Physical Activity and Mortality Across Levels of Adiposity Open
Low physical activity and adiposity were both associated with a higher risk of premature mortality, but high physical activity attenuated the increased risk with adiposity irrespective of adiposity metric, except in those with a BMI ≥35 kg…
Joint associations of accelerometer-measured physical activity and sedentary time with all-cause mortality: a harmonised meta-analysis in more than 44 000 middle-aged and older individuals Open
Objectives To examine the joint associations of accelerometer-measured physical activity and sedentary time with all-cause mortality. Methods We conducted a harmonised meta-analysis including nine prospective cohort studies from four count…
