				        	Objective To understand the physical endurance level of primary and middle school students in China in 2014,and identify the factors influencing students' physical endurance.Methods Data were collected from "National School Student Physical Fitness and Health Surveillance in 2014",a total of 142 708 primary and middle school students with complete information were included in the analysis.The age,gender and area specific failure rates of endurance running of students were analyzed,the differences were analyzed with x2 test,and the factors influencing students' physical endurance were identified with log-binomial regression model.Results Among the 142 708 students,the failure rate of endurance running was 21.6% (30 867/142 708).The failure rate was 23.7% (16 891/71 388) in boys and 19.6% (13 976/71 320) in girls (x2=347.73,P<0.05).And it was 24.8% in students in urban area (17 713/71 378),higher than that in students in rural area (18.4%,13 154/71 330) (x2=855.29,P<0.05).The failure rate of endurance running showed an upward trend with age.Insufficient physical education class hour (OR=1.13,95%CI:1.11-1.15),not taking breakfast daily (OR=1.22,95% CI:1.20-1.25),daily physical exercise time < 1 hour (OR=1.44,95%CI:1.40-1.48),the screen watching time >2 hours (OR=1.16,95%CI:1.14-1.19) and overweight or obesity (OR=1.90,95% CI:1.86-1.95) might be the risk factors for the failure of physical endurance.Conclusion The physical endurance of primary and secondary students in China was not optimistic,and the factors influencing their physical endurance included gender,living area,physical education class time,daily homework time,breakfast,daily exercise time and nutrition status.
