title: [Sleep disorders and their influencing factors in primary school children from Urumqi].
abstract: OBJECTIVE
  To understand the prevalence of sleep disorders and their influencing factors in primary school children from Urumqi.
  
  
  METHODS
  A total of 2034 children at the ages of 6-14 years were randomly sampled in 3 districts of Urumqi. The children's sleep states and their family and social environments were investigated through questionnaires.
  
  
  RESULTS
  The prevalence of sleep disorders in the subjects was 55%. The prevalence of sleep inquietude was the highest (14.7%), followed by sleep talking (4.8%), sleep walking (1.5%), nocturnal enuresis (1.5%), sleep teeth grinding (5.7%), habitual snoring (12.9%), sleep apnea (0.5%), and waking up by choke (1.9%). Taking drugs to stimulate or inhibit the central nervous system, frequent colds, confined housing area, family history, and sleeping with parents were risk factors for the development of sleep disorders.
  
  
  CONCLUSIONS
  The prevalence of sleep disorders within primary school children in Urumqi is higher than the reported data. The development of sleep disorders is multifactorial.
