title: The frequency of common nonmalignant skin conditions in adults in central Victoria, Australia.
abstract: BACKGROUND
  Nonmalignant skin conditions are believed to be common in adults, although there are very few community-based studies to determine their exact frequency.
  
  
  OBJECTIVE
  To record the prevalence of common, nonmalignant skin conditions in adults in central Victoria, Australia.
  
  
  METHODS
  A total of 1457 respondents from a random selection of adults aged 20 years and over from Maryborough, central Victoria, were given a total body examination by a dermatologist or dermatology trainee. People with any nail or skin signs suggestive of tinea had scrapings taken for fungal culture.
  
  
  RESULTS
  The age- and sex-adjusted prevalence of warts was 7.1% (95% confidence interval (CI), 5.8-8.4%), acne 12.8% (95% CI, 11.0-14.5%), atopic dermatitis 6.9% (95% CI, 5.6-8.3%), seborrheic dermatitis 9. 7% (95% CI, 8.2-11.2%), asteatotic dermatitis 8.6% (95% CI, 7.1-10. 0%), psoriasis 6.6% (95% CI, 5.7-7.9%), culture-positive tinea 12% (95% CI, 10.3-13.6%), seborrheic keratoses 58.2% (95% CI, 55.6-60. 7%), and Campbell de Morgan spots (cherry angiomas) 54.4% (95% CI, 51.9-57.0%). There was variation in the prevalence of many of these conditions with age.
  
  
  CONCLUSIONS
  This study demonstrates that nonmalignant skin conditions are common in adults in Australia. Their diagnosis and management represent a considerable burden not only to those suffering from the conditions, but also to the health system which provides for their care.
