Outcomes of a group-randomized trial to prevent excess weight gain, reduce screen behaviours and promote physical activity in 10-year-old children: Switch-Play
Objectives : To evaluate the effectiveness of an intervention to prevent excess weight gain , reduce time spent in screen behaviours , promote participation in and enjoyment of physical activity ( PA ) , and improve fundamental movement skills among children . Participants : In 2002 , 311 children ( 78 % response ; 49 % boys ) , average age 10 years 8 months , were recruited from three government schools in low socioeconomic areas of Melbourne , Australia . Design : Group-r and omized controlled trial . Children were r and omized by class to one of the four conditions : a behavioural modification group ( BM ; n=66 ) ; a fundamental movement skills group ( FMS ; n=74 ) ; a combined BM/FMS group ( BM/FMS ; n=93 ) ; and a control ( usual curriculum ) group ( n=62 ) . Data were collected at baseline , post intervention , 6- and 12-month follow-up periods . Results :  BMI data were available for 295 children at baseline and 268 at 12-month follow-up . After adjusting for food intake and PA , there was a significant intervention effect from baseline to post intervention on age- and sex-adjusted BMI in the BM/FMS group compared with controls ( −1.88 kg m−2 , P<0.01 ) , which was maintained at 6- and 12-month follow-up periods ( −1.53 kg m−2 , P<0.05 ) . Children in the BM/FMS group were less likely than controls to be overweight/obese between baseline and post intervention ( adjusted odds ratio (AOR)=0.36 , P<0.05 ) ; also maintained at 12-month follow-up ( AOR=0.38 , P<0.05 ) . Compared with controls , FMS group children recorded higher levels and greater enjoyment of PA ; and BM children recorded higher levels of PA and TV viewing across all four time points . Gender moderated the intervention effects for participation in and enjoyment of PA , and fundamental movement skills . Conclusion : This programme represents a promising approach to preventing excess weight gain and promoting participation in and enjoyment of PA . Examination of the mediators of this intervention and further tailoring of the programme to suit both genders is required
