title: Occurrence and impact of xerostomia among dentate adult New Zealanders: findings from a national survey.
abstract: BACKGROUND
  We investigated the prevalence, associations and impact of xerostomia in a nationally representative sample of dentate adult community-dwelling New Zealanders aged 18 years and over.
  
  
  METHODS
  The data were collected from a representative sample of 2209 adults, as part of the 2009 New Zealand Oral Health Survey (NZOHS). Data were collected using face-to-face interviews, dental examinations and the short-form Oral Health Impact Profile (OHIP-14). Data analysis used appropriate weighting for all procedures to account for the complex survey design.
  
  
  RESULTS
  The overall prevalence estimate for xerostomia was 13.1% (95% CI 11.7, 14.7), and it was more common among females. Those in the 75+  and 25-34 age groups were more likely (odds ratios of 6.5 and 4.0, respectively) to have xerostomia. After controlling for sociodemographic characteristics and clinical oral disease, the mean OHIP-14 score among xerostomics was 50% higher than among those who did not have the condition.
  
  
  CONCLUSIONS
  These data indicate that xerostomia is a common condition which can affect quality of life among people of all ages.
