title: A prospective study of epidemiological risk factors for ingestion of fish bones in Singapore.
abstract: BACKGROUND
  Ingestion of fish bones is a common clinical complaint among adult patients. The aim of this study was to evaluate the epidemiological and behavioural risk factors for fish bone ingestion.
  
  
  METHODS
  Between 2009 and 2010, a physician-administered questionnaire was administered to 112 consecutive patients who presented to the emergency department of an adult tertiary hospital with the complaint of fish bone ingestion.
  
  
  RESULTS
  The wearing of dentures, the use of utensils to eat fish and the practice of deboning fish in one's mouth were found to be associated with an increased risk of fish bone ingestion.
  
  
  CONCLUSIONS
  To prevent the occurrence of fish bone ingestion and its possible complications, at-risk populations should be advised on the precautions to take when eating boned fish.
