Aim: the purpose of the present pilot study was to verify the effects of astep goals pedometer interventionon physical activity level and cardiometabolic profile in obese adolescents. Methods: The intervention was designedusing a pilot randomized controlled trial with 19 adolescents. The 8-week intervention included following components: (i) pedometer for physical activity self-monitoring; (ii) individualized goal setting; (iii) parent text messages for social support. The primary outcome was physical activity (PA) and secondary outcomes included cardiometabolic profile. The effects of 8-weeks intervention was analyzed using the generalized estimation equation (GEE) method in a gamma repeated-measures model for the outcomes. Results: A group–time effect was observed after 8-week for physical activityin intervention group (baseline: 7,553 steps/day [IC95% 6036 to 9446]; (post: 11,138 steps/day [IC95% 9255 to 13403]). Conclusion: A 8-week of step goals pedometer interventionwas able to improve the PA but did not cardiometabolic profile in these obese adolescents.
