The daily activity of the participants was recorded by accelerometers,and the results were compared with the recommendation standard for physical activity of Chinese children and adolescents. And the influences of gender,age and gross motor function classification system(GMFCS) on physical activity were ananlyzed. Results The average time of daily sedentary behavior of CP children was(470.73±107.21) min,and daily moderate-to-vigorous physical activity(MVPA) was(40.65±19.05) min. The time for sedentary activity in boys was significantly longer than that of girls(P<0.05). Compared with other age groups,the time for sedentary behavior of CP children aged 4 to 6 years was the least,while the time for MVPA was the most(P<0.001). The GMFCS level was negatively correlated with sedentary activity time,and positively related to MVPA time(P<0.001).Conclusions Physical activity in CP children is significantly lower than the recommended level. Gender,age and GMFCS level are highly correlated with physical activity in CP children. So it is supposed to help CP children reduce sedentary behavior and increase moderate-to-vigorous physical activity in many ways. %U https://manu41.magtech.com.cn/Jwk_zgetbjzz/EN/10.11852/zgetbjzz2019-0149
