Abstract

Objective. To compare the physical fitness of children from eight elementary schools in Morelos, México after the imple­mentation of an intervention to prevent childhood obesity. Materials and methods. 214 children were randomly selected (111 - intervention community and 103 - control community). Physical fitness was evaluated by the 6 minutes walking test and the 50 meters speed test, as well as the number of steps/day. Results. The median of time in the speed test at the intervention site was 11.3 seconds and 13.8 seconds at the control site (p<0.001). The median distance traveled in the walking test was 550 m in the intervention site and 420 m in the control site (p<0.001). The children of the intervention community took a median of 15 161 steps/ day and those of the control community took 13 749 steps/ day (p<0.05). Conclusions. Children from the intervention community have significantly better physical fitness.
