[Objective]To explore the effects of geographics ,personal hygiene and intestinal functions on the incidence of peritonitis in patients of continuous ambulatory peritoneal dialysis (CAPD) .[Methods]A total of 133 hospitalized pa‐tients on peritoneal dialysis at our hospital were recruited during 2008 to 2014 according to the criteria of peritonitis .They were divided into peritonitis and non‐peritonitis groups .Their general information (gender ,age ,place of residence ,edu‐cation level & primary disease ,etc .) and personal hygiene ,etc were recorded .And the relationship was analyzed between these factors and peritoneal dialysis‐related peritonitis .[Results]There were significant inter‐group differences in geo‐graphic region ( P<0 .05) .Risk factors associated with the development of peritonitis included region (township& rural areas) [OR=5 .876 ,P=0 .000] ,washing [OR=5 .596 ,P=0 .009] and brushing [OR=4 .865 ,P=0 .003] and diar‐rhea [OR=5 .744 ,P=0 .006] .[Conclusion]Geographical region ,personal hygiene and diarrhea affects the development of peritonitis .We should enhance the awareness of preventing peritonitis in rural patients and pay more attention to hy‐giene education for peritoneal dialysis patients .%目的探讨地域、个人卫生状况及肠道功能对持续性非卧床腹膜透析（CAPD）患者并发感染性腹膜炎的影响。方法选取2008～2014年在本院行腹膜透析置管术的CAPD患者133例，按腹膜炎诊断标准，分为腹膜炎组和非腹膜炎两组，记录CAPD患者一般资料（性别、年龄、居住地、文化程度、原发病等），个人卫生，腹泻便秘等情况，分析这些因素与感染性腹膜炎之间的关系。结果两组患者长期居住地比较差异具有统计学意义（P＜0．05），而两组患者性别、年龄、身高、体质量、体质量指数、文化程度、原发病、是否合并糖尿病相比较差异无统计学意义（ P ＞0．05）。对两组患者资料采用二分类 Logistic回归分析，结果表示地域（乡镇及农村）[OR＝5．876， P ＝0．000]、个人卫生中洗手[O R＝5．596， P ＝0．009]与刷牙[O R＝4．865， P ＝0．003]、腹泻[O R＝5．744，P ＝0．006]及便秘[OR＝2．332，P ＝0．016]是腹膜炎发生的影响因素。结论地域、个人卫生、腹泻便秘是腹膜炎发生的影响因素，在临床工作中应加强乡镇及农村患者对腹膜炎的预防意识，重视对腹膜透析患者的卫生教育，以减少腹膜透析相关性腹膜炎的发生。
