Associations of adiposity and device-measured physical activity with cancer incidence: UK Biobank prospective cohort study.

Background: High adiposity and low physical activity are associated with cancer risk. Whether different amounts and intensities of physical activity can mitigate this association is unclear. We aimed to examine the independent and combined associations of adiposity and device-measured physical activity levels of different intensities with cancer incidence and mortality.

Physical activity, sedentary time and health - a narrative review with new insights.

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 assessed physical activity. Recent data where physical activity and sedentary time are measured with devices suggest that the dose-response association between device-measured physical activity and risk of incident diseases and mortality is greater and observed at lower levels of physical activity than indicated by self-reported data.

Physical activity and life expectancy: a life-table analysis.

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 disease burden attributable to low PA. This study estimated how much low PA reduces life expectancy, and how much life expectancy could be improved by increasing PA levels for both populations and individuals.

Physical Activity Volume, Intensity, and Mortality: Harmonized Meta-Analysis of Prospective Cohort Studies.

Introduction: It is unclear whether moderate-to-vigorous physical activity (MVPA) is associated with a lower mortality risk, over and above its contribution to total physical activity volume.

Methods: 46,682 adults (mean age: 64 years) were included in a meta-analysis of nine prospective cohort studies. Each cohort generated tertiles of accelerometry-measured physical activity volume and volume-adjusted MVPA.

Device-measured physical activity and sedentary time in the Nordic countries: A scoping review of population-based studies.

Purpose: The purpose of this scoping review was to summarize and describe the methodology and results from population-based studies of physical activity and sedentary time measured with devices in the Nordic countries (Denmark, Finland, Iceland, Norway, and Sweden) and published in 2000 or later.

Methods: A systematic search was carried out in PubMed and Web of Science in June 2023 using predefined search terms.

Results: Fourteen unique research projects or surveillance studies were identified.
