There was some evidence that school-based physical activity interventions had a positive impact on four of the nine outcome measures .

BACKGROUND The World Health Organization ( WHO ) estimates that 1.9 million deaths worldwide are attributable to physical inactivity and at least 2.6 million deaths are a result of being overweight or obese .

Evaluation of a computer-tailored physical activity intervention in adolescents in six European countries: the Activ-O-Meter in the HELENA intervention study.
PURPOSE The present study investigates the effect of the Activ-O-Meter , an internet-based computer-tailored physical activity intervention in adolescents in six European centers involved in the HELENA study . METHODS Adolescents ( 12 - 17 years old ) from Vienna , Ghent , Heraklion , Dortmund , Athens , and Stockholm were r and omized into intervention and control schools . Participants in the intervention condition received the computer-tailored advice at baseline and after 1 month . Participants in the control condition received a generic st and ard advice . Effects were evaluated after 1 ( n = 675 ) and 3 months ( n = 494 ) using multi-level modeling . Physical activity levels were measured using the International Physical Activity Question naire for adolescents ( IPAQ-A ) . RESULTS After 1 month , the intervention group reported higher levels of moderate ( beta = -32.8 , 95 % CI ( confidence interval ) : -64.2 to -1.4 ) and vigorous ( beta = -28.0 , 95 % CI : -50.7 to -5.3 ) physical activity in leisure time , as well as higher levels of cycling for transport ( beta = -19.1 , 95 % CI : -34.4 to -7.6 ) compared to the control group . After 3 months , when the intervention group had received the tailored feedback twice , intervention effects were even stronger . Favorable changes in physical activity levels of all intensities and in different context s were found in the tailored group compared to the control group . Among adolescents not reaching the physical activity recommendations at baseline similar effects as in the total sample were found . CONCLUSIONS The data indicated that the computer-tailored physical activity intervention had positive effects on physical activity levels among the adolescents . However , the implementation of the computer-tailored intervention in the schools was not feasible in all countries
