Abstract: Children's habits are affected by a number of factors. We find that Children' habit disorders are closely related to gender, family environment, academic performance and peer interaction in a series of investigation taken by Care for Children and Adolescents of Wuhan in 2011 and that the poorer the family environment and peer relationships, the more serious the habit disorders, which indicates that it's an effective way to improve children's habit disorders from two directions: family and peers. Therefore, we stress the improvement of the rearing mode, change of educational conception, the establishment of multilateral supportive system, social adaptation of migrant worker families, etc.
