Girls, students in non-key class, cadres students, dieting students, those spending less time on physical exercises or eating less vegetables and fruits or staying up late more often were reported a higher rate of physiological sub-health (P <0. 05). Boarders or students in non-key class had a higher rate of psychological sub-health (P < 0. 05). Non-cadres students, those having less activity or having more time for entertainment or eating less vegetables and fruits had a higher risk of suffering social sub-health (P < 0. 05).
