Introduction: Sleep problems are prevalent among adolescents. Multiple
psychosocial and biological factors are associated with increased
risk for sleep problems in adolescents. However, little is known about
sleep quality and its correlates among adolescents exposed to natural
traumatic events. This study examined the prevalence and correlates
of poor sleep quality among survival adolescents 18 months after 2008
Wenchuan earthquake in China.
Methods: Eighteen months after Wenchuan earthquake in 2008, a questionnaire
survey was conducted in a sample of 1494 8th and 11th graders
in Dujiangyan district, 20 kilometer away from the epicenter. A total of
233 adolescent students as a control group were sampled from a nearby
school district where the students were not exposed to the earthquake.
Participants were asked to fill out a self-administered questionnaire including
the Pittsburgh Sleep Quality Index, Adolescents Self-rating Life
Event Checklist, and Social Support Rating Scale for Children and Adolescents.
Stepwise regression analysis was used to examine significant
predictors of sleep quality.
Results: The mean total PSQI score was significantly higher in exposure
group (Mean=5.89, SD=2.84) than in control group (Mean=4.82,
SD=2.6) (p
