Results In 2016,the proportion of Chinese students who spent less than 1 hour,1~2 hours,2~4 hours and more than 4 hours for outdoor activities per day was 35.3%,39.0%,18.4% and 7.3% respectively.For the prevalence of less than 1 hour outdoor activity per day:female students (39.3%) was higher than male students (31.1%),suburban counties (36.9%) were higher than urban areas (34.2%),regular high school (48.5%)> university (39.8%)> junior high school (32.6%)> vocational high school (31.4%)> primary school (27.4%),poor social-economical region(36.6%)> medium social-economical region (35.2%)> good social-economical region (34.0%),central provinces (38.8%)> western provinces (35.2%)> eastern provinces (32.8%),the differences were all statistically significant (P<0.001).The prevalence of less than 1 hour outdoor activity per day changed with the grade significantly,peaking at third year in high school,which was closely related to academic burden.Gender differences became obvious after junior one.Hebei,Jiangxi,Henan,Anhui had the highest prevalence of less than 1 hour outdoor activity per day (more than 40%),while Beijing,Fujian,Guangdong showed the lowest prevalence (less than 30%).
