title: Public awareness and knowledge of prostate cancer in Japan: results of a survey at short-stay examination facilities.
abstract: BACKGROUND
  This study was undertaken to determine public awareness and knowledge of prostate cancer, which has not been adequately studied in Japan.
  
  
  METHODS
  Assessment was made of public awareness and perception of prostate cancer in Japan, based on health examination data for participants in a short-stay physical examination program ("human dry dock"). A multiple-choice, thirty-point questionnaire survey was conducted at 3 "human dry dock" medical facilities situated in urban areas.
  
  
  RESULTS
  Many Japanese adults appeared to be inadequately aware of prostate cancer and of the means available for its early detection. One third of the participants were unfamiliar with this malignancy. Logistic regression analysis indicated smoking to be the only covariate associated with lack of knowledge of prostate cancer (P< 0.05). Seventy-one percent of the subjects had heard of digital rectal examination, but only 16% and 8%, respectively, were familiar with the terms transrectal ultrasonography and PSA testing. Japanese people may possibly be less informed about prostate cancer than African-American males. Both "human dry dock" facilities and subject gender were significantly associated with knowledge of digital rectal examination (P< 0.05). Knowledge of transrectal ultrasonography was found to depend on participation in "human dry dock" programs and level of education (P< 0.05). Smoking, participation in "human dry dock" programs under employer direction, and health status were all identified as determinants for knowledge of PSA testing (P< 0.05).
  
  
  CONCLUSIONS
  Educational programs should be established and put into effect to instill adequate awareness of prostate cancer in Japan. In a better-informed society, more effort would be directed toward prevention and thus early stage prostate cancer would be detected more often.
