目的调查上海、浙江两地社区中老年男性良性前列腺增生症(BPH)的患病情况。方法按照整群及年龄分层、随机不等比例的抽样方法,对上海城市社区及浙江省农村地区共2 000例40~70岁的常住中老年人群作为调查对象,分别自行记录国际前列腺症状评分(IPSS)评估下尿路症状(LUTS),经直肠超声检测前列腺各径线的大小并计算其体积(PV),将其结果进行方差分析。结果符合标准的研究对象1 982例,平均年龄(57.85±8.33)岁,IPSS(5.43±3.21)分,PV(29.86±20.32)mL,中、重度LUTS为50.61%(1003/1982)、PV>20mL者占68.92%(1 366/1 982),前列腺增生总患病率为29.97%,按年龄分组,40岁~、50岁~和60~70岁者的BPH患病率分别为2.03%、24.89%和54.18%,随年龄的增长BPH的患病率增加,差异具统计学意义(P<0.01)。上海城市社区的BPH患病率为36.58%,而农村地区为23.42%。结论我国社区中老年男性BPH患病率较高,城市社区患病率高于农村地区,应予以高度关注。
Objective To investigate the prevalence of benign prostatic hyperplasia (BPH) in middle-aged and elderly men in Shanghai and Zhejiang. Methods A total of 2 000 elderly people aged 40-70 years in Shanghai city community and rural areas in Zhejiang Province were surveyed according to stratified random sampling and age-stratified random sampling methods. The International Prostate Symptom Score (IPSS) to assess the lower urinary tract symptoms (LUTS). The size of each diameter of the prostate was measured by transrectal ultrasound and the volume (PV) was calculated. The results were analyzed by ANOVA. Results A total of 1 982 subjects were eligible, with a mean age of 57.85 ± 8.33 years, IPSS (5.43 ± 3.21), PV (29.86 ± 20.32) mL, moderate and severe LUTS of 50.61% (1003/1982), PV> 20mL accounted for 68.92% (1 366/1 982), the total prevalence of benign prostatic hyperplasia was 29.97%. The prevalence of BPH by age group, 40 years old, 50 years old and 60-70 years old were 2.03% 24.89% and 54.18%, respectively. The prevalence of BPH increased with age, with statistical significance (P <0.01). The prevalence of BPH in urban communities in Shanghai was 36.58%, compared to 23.42% in rural areas. Conclusion The prevalence of BPH in middle-aged and elderly men in our community is high, and the prevalence of urban community is higher than that in rural areas, so we should pay close attention to it.
