Changes in time-segment specific physical activity between ages 10 and 14 years: A longitudinal observational study

  • Published on Jan. 2016

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% ...

The independent prospective associations of sedentary time, moderate and vigorous physical activity with adiposity in young adolescents

  • Presented on May 21, 2014

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 ...

Rainfall and physical activity; what happens as children age?

  • Presented on May 21, 2014

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 ...

Children’s sedentary behaviour: descriptive epidemiology and associations with objectively-measured sedentary time.

  • Published on Nov. 25, 2013

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 ...

More of the same or a change of scenery: an observational study of variety and frequency of physical activity in British children

  • Published on Aug. 16, 2013

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 ...

Individual, socio-cultural and environmental predictors of uptake and maintenance of active commuting in children: longitudinal results from the SPEEDY study

  • Published on July 2013

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 ...
