Measuring change in trials of physical activity interventions: A comparison of self-report questionnaire and accelerometry within the PACE-UP trial 11 Medical and Health Sciences 1117 Public Health and Health Services
(Peer reviewed; Journal article, 2019)Background: Few trials have compared estimates of change in physical activity (PA) levels using self-reported and objective PA measures when evaluating trial outcomes. The PACE-UP trial offered the opportunity to assess ... -
Mechanical and free living comparisons of four generations of the Actigraph activity monitor
(Journal article; Peer reviewed, 2012-09-12)Background More studies include multiple generations of the Actigraph activity monitor. So far no studies have compared the output including the newest generation and investigated the impact on the output of the activity ... -
Multicollinear physical activity accelerometry data and associations to cardiometabolic health: Challenges, pitfalls, and potential solutions
(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 ... -
New global guidelines on sedentary behaviour and health for adults: Broadening the behavioural targets
(Peer reviewed; Journal article, 2020)Background: In 2018, the World Health Organisation (WHO) commenced a program of work to update the 2010 Global Recommendations on Physical Activity for Health, for the first-time providing population-based guidelines on ... -
Objectively measured physical activity and sedentary time in youth: the International children’s accelerometry database (ICAD).
(Journal article; Peer reviewed, 2015-09-17)Background: Physical activity and sedentary behaviour in youth have been reported to vary by sex, age, weight status and country. However, supporting data are often self-reported and/or do not encompass a wide range ... -
Objectively measured physical activity in four-year-old British children: a cross-sectional analysis of activity patterns segmented across the day
(Journal article; Peer reviewed, 2014-01-09)BACKGROUND: Little is known about preschool-aged children's levels of physical activity (PA) over the course of the day. Using time-stamped data, we describe the levels and patterns of PA in a population-based ... -
Objectively recorded physical activity in pregnancy and postpartum in a multi-ethnic cohort: association with access to recreational areas in the neighbourhood
(Journal article; Peer reviewed, 2016-07-07)Background: Physical activity may reduce the risk of adverse pregnancy outcomes; however, compared to non-pregnant women, a lower proportion of pregnant women meet the physical activity guidelines. Our objectives were to ... -
Perceived family functioning and friendship quality: cross-sectional associations with physical activity and sedentary behaviours
(Journal article; Peer reviewed, 2015-02-21)Background: This study examined the association of adolescent-reported family functioning and friendship quality with objectively-measured moderate to vigorous physical activity (MVPA), sedentary time, and self-reported ... -
Physical activity levels objectively measured among older adults: a population-based study in a Southern city of Brazil
(Journal article; Peer reviewed, 2017-02)Background: Low levels of physical activity are currently observed in all age groups around the world. Among older adults physical activity is even lower, potentially influencing quality of life, incidence of diseases and ... -
Predictors of change differ for moderate and vigorous intensity physical activity and for weekdays and weekends: a longitudinal analysis
(Journal article; Peer reviewed, 2013)Background Predictors of physical activity (PA) change are rarely investigated separately for different PA intensities and for weekdays/weekends. We investigated whether individual-level predictors of one-year change ... -
Prenatal, birth and early life predictors of sedentary behavior in young people: a systematic review
(Journal article; Peer reviewed, 2016-06-07)Background: Our aim was to systematically summarize the evidence on whether prenatal, birth and early life factors up to 6 years of age predict sedentary behavior in young people (≤18 years). Methods: PRISMA guidelines ... -
Process evaluation design in a cluster randomised controlled childhood obesity prevention trial: the WAVES study
(Journal article; Peer reviewed, 2014-09-10)The implementation of a complex intervention is heavily influenced by individual context. Variation in implementation and tailoring of the intervention to the particular context will occur, even in a trial setting. It is ... -
Reference values for wrist-worn accelerometer physical activity metrics in England children and adolescents
(Peer reviewed; Journal article, 2023)Background: Over the last decade use of raw acceleration metrics to assess physical activity has increased. Metrics such as Euclidean Norm Minus One (ENMO), and Mean Amplitude Deviation (MAD) can be used to generate metrics ... -
Revising on the run or studying on the sofa: prospective associations between physical activity, sedentary behaviour, and exam results in British adolescents.
(Journal article; Peer reviewed, 2015-09-04)Background: We investigated prospective associations between physical activity/sedentary behaviour (PA/SED) and General Certificate of Secondary Education (GCSE) results in British adolescents. Methods: Exposures were ... -
Sedentary patterns, physical activity and health-related physical fitness in youth: a cross-sectional study
(Journal article; Peer reviewed, 2017-03-04)Background: Strong evidence indicates that moderate-vigorous physical activity (MVPA) is positively associated with fitness in youth, independent of total sedentary-time. Sedentary-time appears negatively associated with ... -
Stability and change in potential correlates of physical activity and association with pubertal status among Norwegian children in the transition between childhood and adolescence.
(Journal article; Peer reviewed, 2012-05-11)Background Whereas tracking and change in physical activity (PA) in children and adolescents have been well documented, studies investigating these patterns in its correlates are lacking. The present study aims to address ... -
Substituting prolonged sedentary time and cardiovascular risk in children and youth: a meta-analysis within the International Children’s Accelerometry database (ICAD)
(Peer reviewed; Journal article, 2019)Background: Evidence on the association between sitting for extended periods (i.e. prolonged sedentary time (PST)) and cardio-metabolic health is inconsistent in children. We aimed to estimate the differences in cardiometabolic ... -
Systematic mapping review of the factors influencing physical activity and sedentary behaviour in ethnic minority groups in Europe: a DEDIPAC study
(Journal article; Peer reviewed, 2017-07-24)Background: Physical activity and sedentary behaviour are associated with health and wellbeing. Studies indicate that ethnic minority groups are both less active and more sedentary than the majority population and that ... -
