Objective To study sleep status of primary and secondary school students in four cities and effects of their family environment,and to provide basis for developing appropriate interventions.Methods A stratified random cluster sampling method was used to recruit subjects.A total of 10 079 primary and secondary students and their parents selected from Shenyang,Guangzhou,Wuhan and Chengdu received a questionnaire survey to collect information about sleep status.Results The average sleeping time of primary and middle school students in the four cities was(7.8± 1.5) h,and the rate of insufficient sleeping was 78.7%;Sleeping time was gradually decreased with the school stage increasing(F=2.342.243,P<0.01).The rate of insufficient sleeping in junior high school students was highest,and the rate of girls (76.1%) was higher than boys(72.4%),the urban was higher than the suburbs.Students were more likely to sleep less if their parents were lack of sleep.The influencing factors of the insufficient sleeping of primary and secondary school students included school stage,parents' age,parents' educational level,family residence and parents' sleep condition(P<0.05).Conclusion The insufficient sleeping of primary and secondary school students are common in four cities.In addition to the influence of the school stage,the family environment has a certain influence on the students' sleeping.
