title: Sleep of M&#257;ori and non-M&#257;ori of Advanced Age.
abstract: OBJECTIVE
  To estimate prevalence and identify predictors and outcomes of reporting sleep problems in M&#257;ori and non-M&#257;ori of advanced age.
  
  
  METHODS
  Participants were 251 M&#257;ori, and 398 non-M&#257;ori adults (79-90 years) from Te Pu&#257;waitanga o Ng&#257; Tapuwae Kia Ora Tonu. Life and Living in Advanced Age: A Cohort Study in New Zealand. Multiple logistic regression identified predictors of reporting a current sleep problem and investigated relationships between current sleep problems and physical and mental health.
  
  
  RESULTS
  26.3% of M&#257;ori and 31.7% of non-M&#257;ori reported a current sleep problem. Reporting a current sleep problem was associated with ethnicity (non-M&#257;ori, adjusted OR=0.52, 95% CI=0.30-0.90), and reporting a past sleep problem (adjusted OR=2.67, 95% CI=1.25-5.72). Sleep problems were related to poorer physical and mental health, and falling.
  
  
  CONCLUSIONS
  Sleep problems are commonly reported and associated with poorer health. Early recognition and management of sleep problems could improve physical and mental health.
