Bottom Line: The purpose of the present paper was to evaluate its short term effects.No significant intervention effects were observed, neither for self-reported TV/DVD or computer/game console time, nor for accelerometer-assessed total sedentary time and number of breaks in sitting time.Overall, these results do not warrant wider dissemination of the present UP4FUN intervention.

ABSTRACT

Background: The UP4FUN intervention is a family-involved school-based intervention aiming at reducing and breaking up sitting time at home (with special emphasis on screen time), and breaking up sitting time in school among 10-12 year olds in Europe. The purpose of the present paper was to evaluate its short term effects.

Methodology/principal findings: A total of 3147 pupils from Belgium, Germany, Greece, Hungary and Norway participated in a school-randomized controlled trial. The intervention included 1-2 school lessons per week for a period of six weeks, along with assignments for the children and their parents. Screen time and breaking up sitting time were registered by self-report and total sedentary time and breaking up sitting time by accelerometry. The effect of the intervention on these behaviors was evaluated by multilevel regression analyses. All analyses were adjusted for baseline values and gender. Significance level was p≤0.01. No significant intervention effects were observed, neither for self-reported TV/DVD or computer/game console time, nor for accelerometer-assessed total sedentary time and number of breaks in sitting time. The intervention group, however, reported more positive attitudes towards (β = 0.25 (95% CI 0.11, 0.38)) and preferences/liking for (β = 0.20 (95% CI 0.08, 0.32)) breaking up sitting time than the control group.

Conclusions/significance: No significant intervention effect on self-reported screen time or accelerometer-assessed sedentary time or breaks in sitting time was observed, but positive effects on beliefs regarding breaking up sitting time were found in favor of the intervention group. Overall, these results do not warrant wider dissemination of the present UP4FUN intervention.

pone.0122612.g001: Flow Diagram of UP4FUN schools with participating children.Enrollment and randomization of schools, number of children at baseline and follow-up and number of children analyzed (intervention and control).

Mentions: In total, 62 schools participated (participation rate 41%); 31 intervention schools (including 105 classes implementing the intervention) and 31 control schools (including 114 classes). In these schools there were 5117 eligible pupils, of which 3394 (66%) were given parental consent. Of these pupils, a total of 3325 pupils completed the pre-test survey, 3232 completed the post-survey and 3147 pupils completed both surveys (Fig 1). These 3147 pupils constitute the study sample for the present outcome evaluation; 1569 intervention pupils and 1578 control pupils. Out of the 3147 pupils, 584 wore accelerometers at pre-test or post-test due to limited availability of accelerometers. Of these, 150 wore accelerometers at both time points and had valid data, and thereby constitute the study sample for the accelerometer analyses.
