Abstract
A case control study was conducted on 100 patients with benign prostatic hypertrophy (BPH) and 100 controls matched by age and residence. Interviews were performed by well‐ trained urologists using an original questionnaire. Matched‐pair analysis revealed the following characteristics and relative risks (RR) as being significantly (P < 0.05) different among the BPH patients versus the controls: higher educational background (RR = 2.77); not engaged in farming, forestry, or fishing (RR = 4.82); no environmental pollution at work (RR = 2.90); a present annual income of more than 2,400,000 yen (RR = 3.84); a previous annual income of more than 2,400,000 yen (RR = 3.82); practice the highest standard of living (RR = 4.24); more than two children (RR = 2.67); experienced first nocturnal emission before reaching the age of 20 (RR = 3.11); expending more than 10 min to complete one act of sexual intercourse (RR = 2.43); having no episode of sexual impotence that lasted more than 1 month (RR = 2.29); no family history of gastric ulcer (RR = 7.98); no family history of breast cancer (RR = 8.25); regular consumption of milk (RR = 2.25); irregular consumption of green and yellow vegetables (RR = 3.91); and pickles not consumed at every meal (RR = 1.99). Characteristics that did not achieve a high level of statistical significance (0.05 < P < 0.10) between cases and controls were as follows: past history of gonorrhea, urethritis, or prostatitis and syphilis (RR = 1.84, 2.76, and 4.26, respectively), and daily meat consumption (RR = 3.18). On the basis of interviews of the patients and cases reported in this study, we conclude that dietaly and sexual habits may be important factors which place individuals at a higher risk for developing BPH.
