Methods: A multi-stage stratified cluster random sampling was used to conduct a questionnaire survey for 5 540 students in grades 3-9 in Guiyang. Results: The report rate of dental caries decreases with the increase of school age(P<0.05), and the reporting rate of myopia and the appearance of sexual development characteristics increases with the increase of school age(P<0.05). Proportion of middle and primary school students who could get enough sleep every day(17.6% and 22.0%) and one hour of outdoor activities every day(13.9% and 20.9%) was relatively low.The proportion of graduating students with running away from home and suicide/self-injury ideas/plans and behaviors was higher than other grades in the same school period(P<0.05).The proportion of middle school female students who have thoughts/plans of running away from home, suicidal/self-injury plans and behaviors was higher than that of male students.Students with greater academic pressure,fewer friends,and lack of communication with their parents were more likely to have thoughts/plans or behaviors of running away from home and suicide/self-harm(P<0.05). There were 4 600 students(83.3%) who expressed the demands for health education.School was the primary source of health knowledge for students,with the class meetings accounted for the most practices.Health education on healthy behaviors and lifestyles were highly expected.
