Results Among the 2 149 participants, 386 (18.0%) were found Internet addictive. Prevalence of Internet addition differed significantly among students with different gender, grade, whether smoking or drinking, whether have corporal punishment from parents, sleep duration and body mass index ( P <0.05). Depressive symptom scores differed in students with smoking, corporal punishment from parents and insufficient sleep duration ( P <0.05).
