| Research Abstract |
To evaluate the relationship between the prostate volume and diet especially vitamin A, we conducted an epidemiological study by questionnairing and blood examination.This questionnaire contained 6 items which addressed eating habits, smoking and alcohol drinking.. Blood examination (retinal, beta-carotene, retinol binding protein, total cholesterol and trigliceride) and measurement of the prostate volume were performed in 160 subjects aged 50 years or more. The prostate volume was examined by transrectal ultra sonography (TRUS) and classified into the normal prostate and benign prostate hypertrophy (BPH).
In this study, the statistically significant characteristics of the BPH group were the low smoking rate and high serum beta-carotene levels.Retinol and retinol binding protein showed no significant difference.
These results suggested that serum beta-carotene has some influence on the prostate volume and occurrence of disease.
