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 epoch setting is decisive for associations between physical activity and metabolic health in children
(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 ... -
Accuracy of a combined heart rate and motion sensor for assessing energy expenditure in free-living adults during a double-blind crossover caffeine trial using doubly labeled water as the reference method.
(Journal article; Peer reviewed, 2015-01)Background/Objectives: A combined heart rate (HR) and motion sensor (Actiheart) has been proposed as an accurate method for assessing total energy expenditure (TEE) and physical activity energy expenditure (PAEE). ... -
Are self-report measures able to define individuals as physically active or inactive?
(Journal article; Peer reviewed, 2016-02)Purpose: Assess the agreement between commonly used self-report methods compared with objectively measured physical activity (PA) in defining the prevalence of individuals compliant with PA recommendations. Methods: Time ... -
Body fat related to daily physical activity and insulin concentrations in non-diabetic children
(Peer reviewed; Journal article, 2008-06-28)This study explored the associations between body fat versus daily physical activity and insulin concentrations in non-diabetic young children in a cross-sectional study of 172 children (93 boys and 79 girls) aged 8–11 ... -
Breakfast consumption and physical activity in adolescents: daily associations and hourly patterns
(Journal article; Peer reviewed, 2013-11-27)BACKGROUND: The association between breakfast consumption and physical activity (PA) is inconclusive. OBJECTIVE: We aimed to investigate daily associations and hourly patterns of PA and breakfast consumption in ... -
Calibration and cross-validation of a wrist-worn Actigraph in young preschoolers
(Journal article; Peer reviewed, 2015-02-06)Objective: To calibrate the Actigraph GT3X+ accelerometer for wrist-worn placement in young preschoolers by developing intensity thresholds for sedentary, low- and high-intensity physical activity. Furthermore, to ... -
Changes in time-segment specific physical activity between ages 10 and 14 years: A longitudinal observational study
(Journal article; Peer reviewed, 2016-01)Objectives: Describe (1) time-segment specific changes in physical activity (PA) into adolescence, (2) differences in change in PA between specific time-segments (weekdays–weekends, in-school–out-of-school, out-of-school–weekends, ... -
Correlates of accelerometer-assessed physical activity in pregnancy?: The 2015 Pelotas (Brazil) Birth Cohort Study
(Journal article; Peer reviewed, 2018)Objective methods to measure physical activity (PA) have become available and widely used given the high degree of precision to evaluate PA. However, few studies have used accelerometers to measure PA during pregnancy, ... -
Criterion validity of two physical activity and one sedentary time questionnaire against accelerometry in a large cohort of adults and older adults
(Peer reviewed; Journal article, 2020)Objectives: We compared the ability of physical activity and sitting time questionnaires (PAQ) for ranking individuals versus continuous volume calculations (physical activity level (PAL), metabolic equivalents of task ... -
Cross-Sectional Associations of Reallocating Time Between Sedentary and Active Behaviours on Cardiometabolic Risk Factors in Young People : An International Children’s Accelerometry Database (ICAD) Analysis
(Peer reviewed; Journal article, 2018)Introduction Sedentary time and time spent in various intensity-specific physical activity are co-dependent, and increasing time spent in one behaviour requires decreased time in another. Objective The aim of the present ... -
Daily physical activity and sports participation among children from ethnic minorities in Denmark
(Journal article; Peer reviewed, 2011-12-12)The purpose of this study was to investigate whether Danish children from immigrant backgrounds are less physically active than children from the ethnic majority, and to investigate the possible reasons for any differences ... -
Daily physical activity related to aerobic fitness and body fat in an urban sample of children
(Peer reviewed; Journal article, 2008-02-03)This study evaluates associations between objectively measured daily physical activity vs aerobic fitness and body fat in children aged 8–11 years. A cross-sectional study of 225 children aged 7.9–11.1 years was performed. ... -
Device-measured physical activity and cardiovascular disease risk in adolescent childhood cancer survivors: A physical activity in childhood cancer survivors (PACCS) study
(Peer reviewed; Journal article, 2022)Objectives: We aimed to compare cardiovascular disease (CVD) risk factors in childhood cancer survivors (CCS) with age- and sex-stratified reference material and examine the association between physical activity (PA) ... -
Health-related aspects of objectively measured daily physical activity in children
(Peer reviewed; Journal article, 2008-02-03)It is well established that physical inactivity in adults is associated with increased mortality and morbidity. Whether daily physical activity level is related to risk factors for cardiovascular disease (CVD) in children ... -
High-intensity events in international women’s team handball matches

(Journal article; Peer reviewed, 2013-08-27)OBJECTIVE: To determine the relationship between change in physical activity level and change in directly measured maximal aerobic fitness in severely obese subjects participating in a 1-year lifestyle intervention, and ... -
Joint associations of physical activity and sedentary time with body mass index: A prospective study of mortality risk
(Peer reviewed; Journal article, 2022)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 ... -
