Accelerometer epoch setting is decisive for associations between physical activity and metabolic health in children
Aadland, Eivind; Andersen, Lars Bo; Anderssen, Sigmund Alfred; Resaland, Geir Kåre; Kvalheim, Olav Martin (Peer reviewed; Journal article, 2019)When analysing physical activity (PA) levels using accelerometry, the epoch setting is critical to capture intensity-specific PA correctly. The aim of the present study was to investigate the PA intensity signatures related ... -
Active Smarter Kids (ASK): rationale and design of a cluster-randomized controlled trial investigating the effects of daily physical activity on children's academic performance and risk factors for non-communicable diseases
Resaland, Geir Kåre; Moe, Vegard Fusche; Aadland, Eivind; Steene-Johannessen, Jostein; Glosvik, Øyvind; Andersen, John Roger; Kvalheim, Olav Martin; McKay, Heather A.; Anderssen, Sigmund A. (Journal article; Peer reviewed, 2015-07-28)Background: Evidence is emerging from school-based studies that physical activity might favorably affect children’s academic performance. However, there is a need for high-quality studies to support this. Therefore, the ... -
Associations of lipoprotein particle profile and objectively measured physical activity and sedentary time in schoolchildren: A prospective cohort study
Jones, Paul Remy; Rajalahti, Tarja; Resaland, Geir Kåre; Aadland, Eivind; Steene-Johannessen, Jostein; Anderssen, Sigmund Alfred; Bathen, Tone Frost; Andreassen, Trygve; Kvalheim, Olav Martin; Ekelund, Ulf (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 ... -
Associations of volumes and patterns of physical activity with metabolic health in children: A multivariate pattern analysis approach
Aadland, Eivind; Andersen, Lars Bo; Anderssen, Sigmund Alfred; Resaland, Geir Kåre; Kvalheim, Olav Martin (Journal article; Peer reviewed, 2018)Physical activity (PA) favorably affects metabolic health in children, but it is unclear how total volumes versus patterns (bouts and breaks) of PA relate to health. By means of multivariate pattern analysis that can handle ... -
Cardiometabolic associations between physical activity, adiposity, and lipoprotein subclasses in prepubertal Norwegian children
Rajalahti, Tarja; Aadland, Eivind; Resaland, Geir Kåre; Anderssen, Sigmund Alfred; Kvalheim, Olav Martin (Peer reviewed; Journal article, 2021)Lipoprotein subclasses possess crucial cardiometabolic information. Due to strong multicollinearity among variables, little is known about the strength of influence of physical activity (PA) and adiposity upon this ... -
Cross-sectional and prospective associations between aerobic fitness and lipoprotein particle profile in a cohort of Norwegian schoolchildren
Jones, Paul Remy; Rajalahti, Tarja; Resaland, Geir Kåre; Aadland, Eivind; Steene-Johannessen, Jostein; Anderssen, Sigmund Alfred; Bathen, Tone Frost; Andreassen, Trygve; Kvalheim, Olav Martin; Ekelund, Ulf (Peer reviewed; Journal article, 2021)Background and aims: The associations between aerobic fitness and traditional measures of lipid metabolism in children are uncertain. We investigated whether higher levels of aerobic fitness benefit lipoprotein metabolism ... -
Influence of adiposity and physical activity on the cardiometabolic association pattern of lipoprotein subclasses to aerobic fitness in prepubertal children
Rajalahti, Tarja; Aadland, Eivind; Resaland, Geir Kåre; Anderssen, Sigmund Alfred; Kvalheim, Olav Martin (Peer reviewed; Journal article, 2021)Aerobic fitness (AF) and lipoprotein subclasses associate to each other and to cardiovascular health. Adiposity and physical activity (PA) influence the association pattern of AF to lipoproteins almost inversely making it ... -
Multicollinear physical activity accelerometry data and associations to cardiometabolic health: Challenges, pitfalls, and potential solutions
Aadland, Eivind; Kvalheim, Olav Martin; Anderssen, Sigmund Alfred; Resaland, Geir Kåre; Andersen, Lars Bo (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 ... -
The multivariate physical activity signature associated with metabolic health in children and youth: An International Children's Accelerometry Database (ICAD) analysis
Aadland, Eivind; Kvalheim, Olav Martin; Hansen, Bjørge Herman; Kriemler, Susi; Ried-Larsen, Mathias; Wedderkopp, Niels; Sardinha, Luis B.; Møller, Niels Christian; Hallal, Pedro C.; Anderssen, Sigmund Alfred; Northstone, Kate; Andersen, Lars Bo (Peer reviewed; Journal article, 2020)There is solid evidence for an association between physical activity and metabolic health outcomes in children and youth, but for methodological reasons most studies describe the intensity spectrum using only a few summary ... -
Physical activity versus sedentary behavior: Associations with lipoprotein particle subclass concentrations in healthy adults
Aadland, Eivind; Andersen, John Roger; Anderssen, Sigmund A.; Kvalheim, Olav Martin (Journal article; Peer reviewed, 2013-12-27)Physical activity (PA) and sedentary behavior (SED) may have independent effects on health and disease. This might be due to PA and SED having distinct effects on lipoprotein metabolism. The aim of this study was to determine ... -
The multivariate physical activity signature associated with metabolic health in children
Aadland, Eivind; Kvalheim, Olav Martin; Anderssen, Sigmund Alfred; Resaland, Geir Kåre; Andersen, Lars Bo (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 ...
