A longitudinal analysis of the relationships of physical activity and body fat with nerve growth factor and brain-derived neural factor in children
(Journal article; Peer reviewed, 2018)Background: Nerve growth factor (NGF) and brain-derived neural factor (BDNF) are important for brain function and detectable in the blood. This study explored the longitudinal associations of physical activity and body fat ... -
Associations of volumes and patterns of physical activity with metabolic health in children: A multivariate pattern analysis approach
(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 ... -
Bi-directional prospective associations between objectively measured physical activity and fundamental motor skills in children: a two-year follow-up
(Peer reviewed; Journal article, 2020)Background: The direction of the longitudinal relationship between physical activity (PA) and fundamental motor skills (FMS) remains unclear. We evaluated the bi-directional, prospective relationships between intensity-specific ... -
Bi-directional prospective associations between sedentary time, physical activity and adiposity in 10-year old Norwegian children
(Peer reviewed; Journal article, 2021)There is an adverse cross-sectional association between sedentary time, physical activity (PA) and adiposity, but weak and inconsistent estimates raise question to the direction of associations. The present study aims to ... -
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, ... -
Cross-sectional and prospective associations between physical activity, body mass index and waist circumference in children and adolescents
(Journal article; Peer reviewed, 2017)Objective: To study the cross-sectional and prospective associations between physical activity (PA) of different intensities, body mass index (BMI) and waist circumference (WC) in children and adolescents using isotemporal ... -
Cross-sectional and prospective associations between sleep, screen time, active school travel, sports/exercise participation and physical activity in children and adolescents
(Journal article; Peer reviewed, 2018)Background The aim of this study was to investigate how sleep, screen time, active school travel and sport and/or exercise participation associates with moderate-to-vigorous physical activity (MVPA) in nationally ... -
Interpretation of multivariate association patterns between multicollinear physical activity accelerometry data and cardiometabolic health in children-a tutorial
(Journal article; Peer reviewed, 2019)Associations between multicollinear accelerometry-derived physical activity (PA) data and cardiometabolic health in children needs to be analyzed using an approach that can handle collinearity among the explanatory variables. ... -
Multicollinear physical activity accelerometry data and associations to cardiometabolic health: Challenges, pitfalls, and potential solutions
(Journal article; Peer reviewed, 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
(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 and Sedentary Time Associations with Metabolic Health Across Weight Statuses in Children and Adolescents
(Journal article; Peer reviewed, 2017)Objective: The aim of this study was to examine the prevalence of metabolic health across weight statuses and the associations of physical activity and sedentary time within and across metabolic health-weight status groups. ... -
Physical activity spectrum discriminant analysis—A method to compare detailed patterns between groups
(Peer reviewed; Journal article, 2021)Investigating physical activity (PA) patterns as a detailed intensity spectrum instead of crude intensity categories have improved the ability to analyze the relationship between measured PA and health variables. The aim ... -
Resemblance in accelerometer-assessed physical activity in families with children: The Lolland-Falster Health Study
(Peer reviewed; Journal article, 2020)Background Evidence of intra-family resemblance in physical activity (PA) is lacking. The association between parent and child PA appears weak, the influence of age and gender on this association is uncertain, and no ... -
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 ...
