Article Snippet: Janssen, Basterfield, Parkinson, et al., 2015 , Representative sample - N = 365 - Children and adolescents; 9.3 (±0.4) years at baseline and 12.5 (±0.3) years at follow-up. - Northeast England, UK , Longitudinal prospective study , Theory-driven: Socio-ecological model - 20 measures of potential determinants of changes in both sedentary time and fragmentation between 9 y and 12 y Variables: - Demographic and biological domain (gender; age; BMI; socioeconomic status (SES); maternal age; maternal BMI; parent outside of family home) - Psychological domain (interest in sedentary behaviors) - Behavioral domain (time spent on electronic devices; change in time spent in objectively measured moderate-to-vigorous intensity physical activity (MVPA); attendance at sports clubs) - Socio-cultural environmental domain (parenting rules in relation to sedentary behavior/screen time; parental modelling of sedentary behavior/screen time; parent enjoyment of sedentary behavior/screen time; parent daily sedentary behavior/screen time) - Physical environmental domain (number of TVs in the home; TV in bedroom; computer at home; subscription-based television services available; seasonality) , Direct: Sedentary time and sedentary fragmentation: - ActiGraph accelerometry - In brief, participants were asked to wear the ActiGraph GT1M (ActiGraph Corporation; Pensacola USA) on a waist belt duringwaking hours for 7 days - Sedentary time was expressed in absolute terms (minutes per day) when describing the magnitude of daily sedentary, but in the analyses was expressed as a % of wear time to minimize variation in sedentary time due to wear time. - Sedentary fragmentation was expressed using the fragmentation index - A greater fragmentation index indicates that time spent sedentary is more fragmented (interrupted). , Three-year follow-up Baseline: September 2008 to August 2009 Follow-up: January 2012 to November 2012 - Baseline measures were taken when children were 8–9 y of age (from here on referred to as 9 y) and when children were 11–12 y (from here on referred to as 12 y). , Univariate analyses of determinants associated with change in sitting time: - Child interest in sedentary behavior ( β = 1.12; 95% CI: – 0.20–2.41) - More interest was associated with greater increase in sedentary time..
