Effectiveness of intervention on physical activity of children systematic review and meta analysis of controlled trials with objectively measured outcomes Early. Bird 5. 4Abstract.

Outcomes measured whole day physical activity objectively with accelerometers either before or immediately after the end of the intervention period. Data analysis Intervention effects standardised mean differences were calculated for total physical activity, time spent in moderate or vigorous physical activity, or both for each study and pooled using a weighted random effects model. Meta regression explored the heterogeneity of intervention effects in relation to study participants, design, intervention type, and methodological quality. Results Thirty studies involving 1. The pooled intervention effect across all studies was small to negligible for total physical activity standardised mean difference 0. Plt 0. 0. 1 and small for moderate or vigorous activity 0. Plt 0. 0. 01. Meta regression indicated that the pooled intervention effect did not differ significantly between any of the subgroups for example, for total physical activity, standardised mean differences were 0. P0. 1. 9 0. 0. 7 for body mass index across the entire range and 0. P0. 0. 7 0. 1. 2 for study duration 6 months and 0. P0. 7. 1 0. 1. 5 for homefamily based intervention and 0. P0. 5. 3 and 0. P0. Conclusions This review provides strong evidence that physical activity interventions have had only a small effect approximately 4 minutes more walking or running per day on childrens overall activity levels. This finding may explain, in part, why such interventions have had limited success in reducing the body mass index or body fat of children.

Physical activity is associated with many health benefits,1. Prevention of obesity in particular is thought to be one of the benefits to being more active, and accordingly most interventions aimed at reducing childhood obesity incorporate a physical activity component. Observational studies consistently show that greater activity is associated r0. One explanation, for which some evidence exists,1. Another, yet more fundamental, is that physical activity interventions do not increase the activity of children sufficiently for it to affect adiposity. To date, all systematic reviews that have explored the effectiveness of physical activity interventions on the activity levels of children have had important limitations. For example, the reviews did not confine their analyses to whole day activity or to objectively measured outcomes,1. These reviews included a large proportion of studies that relied on questionnaires, which offer a poor surrogate for objectively measured physical activity r0. More importantly, questionnaires are liable to bias through expectancy, raised awareness, or both. Accelerometers, by contrast, are considered the criterion method for measuring free living activity and correspond well to activity related energy expenditure. The existing reviews also include studies that measured activity only during intervention specific periods of the day for example, physical education classes, breakrecess times, school hours only, and the effects observed during such periods may not be representative of the interventions effect on whole day physical activity. The primary aim of this review was to determine whether, and to what extent, physical activity interventions increase the overall activity of children, using a meta analysis approach. The second aim was to examine the effects of the intervention in relation to potential study level covariates by using meta regression. The review follows the PRISMA guidelines for the preferred conduct and reporting of systematic reviews and meta analyses. Methods. Inclusion criteria. Studies had to meet all of the following criteria for inclusion in this review. PopulationParticipants had to be aged 1. InterventionThe intervention must have incorporated a component that aimed to increase physical activity. The control condition must not have incorporated an activityexercise related element of any kind. The intervention period needed to be at least four weeks. OutcomesPhysical activity must have been measured objectively by using accelerometry in the same participants at both baseline and follow up. We included only studies that measured follow up physical activity before or immediately after the end of the intervention period within four weeks. Whole day activity had to be reported as total physical activity volume usually expressed as mean accelerometer countsminute, time spent in moderate or vigorous intensity activity time spent in activities of at least the intensity of brisk walking, usually expressed as minutesday or proportion of day, or both. We excluded studies that reported only part day activity levels. Study designStudies had to be randomised controlled trials or controlled clinical trials cluster or individual. Search strategy. We searched four electronic databases Embase, Medline, Psyc. INFO, and SPORTDiscus for articles published in peer reviewed journals from January 1. March 2. 01. 2. We imposed no language restriction. We used search terms relevant to childhood child, youth, adolescen juvenile, teen infant boy girl, an activity intervention physical activity, activ exercis training, sedentary, obesity, overweight, BMI, type of trial randomised, controlled, trial, RCT, intervention, and an objective measure of activity objective acceleromet activity monitor, actigraph, MTI, CSA, actical, actiheart, tritrac, unidimensional, triaxial, MVPA.

When the abstract clearly showed that the study was not suitable, the study was discarded. We obtained full text for studies that seemed to be potentially eligible and also for those that could not be excluded on the basis of the abstract information alone. We compared the abstracts selected for full text retrieval by each reviewer at this stage and resolved any discrepancies by discussion. The same two reviewers independently assessed the full text articles and selected studies that met the inclusion criteria, again resolving any discrepancies by discussion. We also searched the reference lists of relevant review articles and of the articles that met the inclusion criteria. Finally, we checked the articles that met the inclusion criteria for duplicate reporting of the same data. Data extraction. One reviewer extracted information on study level covariates and the results of the trial, and a second reviewer checked it.
