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, lesson-time–lunch-time), and (3) associations of change in time-segment specific with overall PA.
Design: Longitudinal observational study (4-year follow-up).
Methods: Children from the SPEEDY study (n = 769, 42% ...
Background: Weather conditions, along with day length, are proposed as the main drivers of the seasonal patterns in children’s physical activity (PA), but little is known about how they affect children at different ages. This study examines the relationship between rainfall and PA in a longitudinal cohort of initially 9–10 ...
Purpose: To assess the associations between 1) baseline objectively-measured activity intensity (sedentary (SED), moderate (MPA) or vigorous (VPA) activity) and 4-year change in adiposity, and between 2) 4-year change in activity intensity and adiposity at follow-up.
Methods: Analyses of longitudinal data from the SPEEDY study, including all participants with valid data at ...
Purpose: Weather conditions, along with day length, are proposed as the main drivers of the seasonal patterns in children’s physical activity (PA). This study examines the relationship between rainfall and PA among 9-10 year old children in Norfolk, UK, and how this changes as they age.
Methods: Participants were 283 ...
Purpose: Objective measurement of school environments is important in determining how they impact children’s physical activity. We have previously developed and tested an audit tool to assess the opportunity for physical activity in primary schools. This study aims to test the validity of the same audit tool in secondary ...
Background: Little is known regarding the patterning and socio-demographic distribution of multiple sedentary behaviours in children. The aims of this study were to: 1) describe the leisure-time sedentary behaviour of 9-10 year old British children, and 2) establish associations with objectively-measured sedentary time.
Methods: Cross-sectional analysis in the SPEEDY study (Sport, Physical ...
Background Physical activity is important for children's health, but successful physical activity promotion is challenging. Whether performing many different types of activities (Variety) is associated with higher physical activity independent of the number of activity sessions (Frequency) is unknown, but this information could inform physical activity promotion and public health ...
Commentary:
Britt Johnson, National Heart Foundation Encouraging children to actively commute to school is a public health strategy that helps to incorporate physical activity into daily life.
This paper presents the results of a longitudinal investigation into the individual, socio-cultural and environmental predictors of active commuting to school amongst 9-10 ...
Background Activity levels are known to decline with age and there is growing evidence of associations between the school environment and physical activity. In this study we investigated how objectively measured one-year changes in physical activity may be associated with school-related factors in 9- to 10-year-old British children.
Methods Data ...
Purpose
To inform intervention development by investigating predictors of one-year change in objectively-measured intensity of physical activity (PA) in a cohort of 9-10 year old British school children.
Methods
In a cohort of 753 children in Norfolk (UK) (41.7% male, baseline age (mean±SD): 9.7±0.4 years) PA was measured over 3 or more days ...
