目的测量20～60岁成年男性的前列腺大小,探讨对前列腺大小有意义的相关影响因素。方法在入选人员知情同意情况下记录其体重、身高、血压、空腹血糖,利用经腹超声对入选者的前列腺进行测量,采用询问法获取被检者的年龄等信息,应用SPSS13.0软件进行统计分析。结果前列腺大小与年龄呈正相关(r=0.41),单因素分析显示不同年龄段男性中,肥胖者与体重正常者、高血压组与非高血压组,糖尿病组与非糖尿病组之间前列腺大小比较差异均有统计学意义(P均<0.05)。吸烟者与不吸烟者、汉族和满族以及不同饮酒程度者之间前列腺大小比较差异无统计学意义(P均>0.05)。多元线性回归分析显示,前列腺大小主要受到年龄、肥胖、高血压的影响。结论年龄、肥胖、高血压是影响前列腺大小的主要因素。
Objective To measure the size of prostate in adult men aged 20 ~ 60 and to explore the relevant factors that have significance on the size of prostate. Methods The body weight, height, blood pressure and fasting blood glucose were recorded under the informed consent of the selected persons. The prostate of the enrolled persons was measured by transabdominal sonography. The age and other information of the subjects were obtained by interrogation method. SPSS13.0 software was used for statistics analysis. Results There was a positive correlation between prostate size and age (r = 0.41). Univariate analysis showed that the prostate size was significantly different between obese and non-hypertensive subjects, between obese subjects and non-hypertensive subjects, between obese subjects and non-diabetic subjects The differences were statistically significant (all P <0.05). There was no significant difference in the size of prostate between smokers and non-smokers, Han and Manchu, and people with different degrees of drinking (all P> 0.05). Multivariate linear regression analysis showed that prostate size was mainly affected by age, obesity and hypertension. Conclusion Age, obesity and hypertension are the main factors affecting the size of the prostate.
