Objective: to investigate the association between objective measures of physical activity levels, physical fitness and screen time in Colombia children and adolescents from Bogota, Colombia. Methods: a sample of 149 healthy Colombian youth, children and adolescents (9-17.9 years old) participated in the study. Physical activity level was assessed over 7 days using an accelerometer. Weight, height, waist circumference, hip waist, subscapular/ triceps skinfold thicknesses and self-reported screen time (television/internet and videogame-viewing time) were measured. Aerobic capacity, handgrip strength, standing broad jump, vertical jump, speed/agility and flexibility were used as indicators of physical fitness. Results: in girls with a high level of physical activity had favorable aerobic capacity (r = 0.366) and inverse relationship with subscapular/triceps skinfold thicknesses (r = -0.257) and (r = -0,237) p < 0.05, respectively. In boys, vigorous physical activity were associated with higher values of flexibility (r = 0.277) and aerobic capacity (r = 0.347), p < 0.05. Finally, the participants who watched 2 h or less of television per day showed 1.81 times (95%CI 1.401 to 2.672) that met physical activity guidelines. Conclusions: the healthy Colombian youth who reported moderate to vigorous objective measures of physical activity levels, presented higher levels in physical fitness especially in aerobic capacity and flexibility and lower values in subscapular/triceps skinfold thicknesses.
