Previous investigations have shown that changes in total prostate volume(TPV) are highly variable among aging men,and a considerable proportion of aging men have a stable or decreasing prostate size.Although there is an abundance of literature describing prostatic enlargement in association with benign prostatic hyperplasia,less is known about the appropriate age cut-off points for TPV growth rate.In this community-based cohort study,TPV was examined once a year in men who had consecutive health checkup,during a follow-up of 4 years.A total of 5058 men(age 18–92 years old) were included.We applied multiple regression analyses to estimate the correlation between TPV growth rate and age.Overall,3232(63.9%) men had prostate growth,and 1826(36.1%) had a stable or decreased TPV during the study period.The TPV growth rate was correlated negatively with baseline TPV(r= –0.32,P〈0.001).Among 2620 men with baseline TPV 〈15 cm^3,the TPV growth rate increased with age(β=0.98,95% CI:0.77%–1.18%) only up to 53 years old.Among 2188 men with baseline TPV of 15–33.6 cm3,the TPV growth rate increased with age(β=0.84,95% CI,0.66%–1.01%) only up to 61 years old after adjusting for factors of hypertension,obesity,baseline TPV,diabetes mellitus and dyslipidemia.In this longitudinal study,the TPV growth rate increased negatively with baseline TPV,only extending to a certain age and not beyond.Further research is needed to identify the mechanism underlying such differences in prostate growth. 展开更多
