肥胖对良性前列腺增生的影响

Effects of Obesity on Benign Prostatic Hyperplasia

目的了解肥胖对成年男性良性前列腺增生(benign prostatic hyperplasia,BPH)的影响。方法收集2011-01/2012-12月在作者医院收治的150例年龄在40岁以上、患BPH、无肥胖相关的代谢性疾病的患者资料。按体质量指数(body mass index,BMI)将其分为正常组(18.5～22.9kg/m2)、超重组(23～24.9kg/m2)、肥胖组(≥25kg/m2);按腰围分为正常腰围组(≤90cm)和腹型肥胖组(>90cm)。比较各分组中前列腺体积和BPH的相关影响因素。结果肥胖显著增加BPH风险。结论BMI及腰围与BPH相关;肥胖是BPH发生发展过程中重要的独立危险因素。

Objective To understand the effect of obesity on benign prostatic hyperplasia of adult males. Methods A total of 150 patients （〉40 years old） with benign prostatic hyperplasia （BPH） and without metabolic disorders related to obesity from January 2011 to December 2012 in our hospital were studied. According to the body mass index （BMI）, the patients were divided into normal group （18. 5-22. 9 kg/m2 ）, overweight group （23-24. 9 kg/m2 ） and obesity group （≥25 kg/m2）. According to the waist circumference, the patients were divided into normal waist circumference group （≤90 cm） and abdominal obesity group （〉90 cm）. The related factors were compared between all the groups. Results Obesity significantly increased the risk of BPH. Conclusion BMI and waist circumference are related with BPH. Obesity is an important independent risk factor in the occurrence and development of BPH.
