| Abstract: |
| 探讨中国直肠肛门闭锁/狭窄的地理空间分布规律，为病因研究提供线索。方法利用2001-2005年中国出生缺陷监测网以医院为基础在全国对孕28周至产后7d的围产儿进行监测的数据，采用两维图论聚类分析对全国监测点按直肠肛门闭锁/狭窄的发生率进行空间归类。 |

| investigate the geographic distribution panem of patients with anorectal atresia/stenosis in China.in order to provide clue for research on its etiology.Methods Data were collected from Chinese Birth Defects Monitoring Network(CBDMN),which was a hospital-based congenital malformations registry system.From 2001 to 2005,all fetuses with more than 28 weeks of gestation and neonates up to 7 days of age,were monitored.Two-dimensional graphic cluster method was used to divide monitoring stations into difierent classes with the incidence rates of anorectal atresia/stenosis.Results The overall incidence of anorectal atresia/stenosis was 3.17 per 10000 during 2001 to 2005.The incidence was higher in Eastern than that in Mid or Western paas of China and tbe difierence was statistically significant(z=2.50,3.69;P=0.012,＜0.001).The monitoring stations were grouped into 6 classes.Class I was with Helongjiang,Jilin and Liaoling;Class Ⅱ was with Fujian,Guangdong,Hainan,Guangxi,and South Hunan and Jiangxi;ClassⅢwas with Beijing,Tianjin,Hebei,Shandong,and Noah Jiangsu and Anhui;Class Ⅳ was with Zhejiang,Shanghai,South Anhui and Jiangsu,Noah Hunan and Jiangxi,Hubei,Henan,Shanxi and Inner Mongolia,Class V was with Ningxia,Gansu and Qinghai;and Class Ⅳ was with Shaanxi,Sichuan,Chongqing,Yunnan,Guizhou.Xinjiang and Tibet.Conclusion Our findings discovered the geographic distribution patterns of patients with anorectal atresia/stenosis in China.It is important to further analyze the relevant environmental factors attached to it so a beRer regional monitoring system for anorectal atresia/stenosis can be operated. |
