title: Lower urinary tract symptoms in relation to lifestyle and medical conditions in Japanese workers.
abstract: OBJECTIVE
  To examine the association of medical conditions and lifestyle with lower urinary tract symptoms (LUTS) in a population of Japanese male workers.
  
  
  METHODS
  A questionnaire survey on LUTS was conducted at the time of a periodic health examination among workers of a group of engineering and shipbuilding companies in Southern Kanto, Japan. A total of 1278 (85%) men responded. LUTS were assessed by using a modified International Prostate Symptom Score questionnaire. Men having at least one point of the score were regarded as positive. Logistic regression analysis was used to examine the relation of the LUTS to age, smoking, drinking, body mass index, and medical treatment of diabetes mellitus, hypertension, and dyslipidemia.
  
  
  RESULTS
  Age was a strong determinant of LUTS. Men undergoing medical treatment for diabetes mellitus were significantly more likely to have LUTS than men without treatment (multivariate-adjusted odds ratio, 1.8; 95% confidence interval, 1.0-3.2). Increased odds of LUTS were also observed in men undergoing medical treatment for hypertension or dyslipidemia. Smoking, drinking alcohol, and obesity were not related to LUTS.
  
  
  CONCLUSIONS
  Our present findings, together with previous epidemiological and experimental evidence, suggest that LUTS might share common etiological factors with diabetes mellitus, hypertension, and dyslipidemia.
