title: The role played by gender and age on poor sleep quality among institutionalized adolescents.
abstract: OBJECTIVE
  The aim of this study was to analyze the prevalence and association between sleep quality with gender and age and to examine the relation between age and the components of the PSQI in institutionalized adolescents.
  
  
  METHODS
  High school internal students of both genders, aged between 14 and 19 years old, were analyzed. After a full clinical evaluation, the Pittsburg Sleep Quality Index Score was obtained from all participants.
  
  
  RESULTS
  We studied 210 participants [male: 15. 7 ± 1.2 years; BMI: 21.7 ± 2.6 kg/m2; female: 15.7 ± 1. 2 years; BMI: 21.9 ± 4.5 kg/m2]. Poor sleep quality was present in 137 (65.3%) participants and was predominant among girls than boys (PSQI = 76.3 vs 55.8%; p < 0.001), respectively. There were positive correlations between PSQI components with age in boys (sleep latency: R = 0.23; p = 0.02; sleep duration: R = 0.28; p < 0.01 and overall sleep quality: R = 0.21; p = 0.03), but not among girls.
  
  
  CONCLUSIONS
  Institutionalized girls have worse sleep quality than boys and positive correlations between sleep quality components with age were only present among boys.
