title: [Chronic bronchitis among 50 and 80 years old males in Iceland. Prevalence and quality of life.].
abstract: OBJECTIVE
  The mortality from chronic bronchitis has been increasing in Iceland during the last decades. Little is however known about the prevalence of this disease and the objective of this study was to find the prevalence of chronic bronchitis in Iceland.
  
  
  METHODS
  In this study a postal questionnaire was sent to all Icelandic males born in the years 1913 (N=388) and 1943 (N=1297) who were alive on the 1st November 1993, asking about several physical symptoms, including symptoms of chronic bronchitis. The response rate was 69.7%.
  
  
  RESULTS
  Altogether 7.1% of 50 years old males and 16.7% of 80 years old males had a history of daily sputum expectoration for at least three months during the last two years. These individuals with chronic bronchitis had a higher prevalence of other respiratory symptoms, such as coughing, wheezing or whistling. History of dyspnea was much higher among those with symptoms of chronic bronchitis. They also complained more often of sleep disturbances and found themselves more stressed than those without symptoms of chronic bronchitis.
  
  
  CONCLUSIONS
  Our study indicates that chronic bronchitis is a frequent illness among Icelandic males. Men with chronic bronchitis frequently have a decreased quality of life, difficulties to move and frequently sleep complaints.
