2010年至2011年中国中部与西部地区骨盆骨折的流行病学对比分析

Epidemiological comparison of pelvic fractures between middle and west areas in China from 2010 to 2011

目的对比分析我国中部与西部地区骨盆骨折的流行病学特征。方法回顾性分析2010年1月至2011年12月期间我国中部和西部地区共42家医院诊治的所有骨盆骨折患者资料，分为4个年龄组：儿童（1～15岁）、青年（16～44岁）、中年（45～59岁）及老年（≥60岁）。将中国中部地区16家医院患者资料定为A组，西部地区26家医院患者资料定为B组，对比分析两组患者的性别、年龄、骨折AO分型等数据。结果共收治5065例骨盆骨折患者，男2531例，女2534例，男女比为1．00：1。骨折高发年龄段为41—50岁（22．80％）。成人高发骨折类型为61．A型（85．19％）。A组患者男女比（0．96：1）低于B组患者（1．04：1），但差异无统计学意义（P〉0．05）。B组患者的平均年龄【（42．0±17．9）岁】显著小于A组患者【（44．6±18．3）岁】，差异有统计学意义（P〈0．05）。A、B组患者的高发年龄段均为41-50岁，构成比分别为23．21％、22．33％，两组比较差异有统计学意义（P〈0．05）。两组青年、中年及老年患者的构成比比较差异均有统计学意义（P〈0．05）。A、B组成人患者高发骨折类型均为61．A型，构成比分别为84．45％、86．08％。两组成人患者骨折AO分型构成比比较差异无统计学意义（P〉0．05）。结论我国中、西部地区骨盆骨折男性与女性患者数量相当，骨折高发年龄段为41～50岁，成人61．A型骨折所占比例偏高。中部地区女性患者多于男性，而西部地区则相反；中部地区患者平均年龄大于西部地区；中、西部地区青年、中年及老年患者的构成比存在差异。

Objective To investigate the epidemiological features of pelvic fractures in the middle and west areas in China from 2010 to 2011. Methods The cluster random sampling method was used to choose 42 hospitals from the middle and west areas in China （16 from the middle as group A and 26 from the west as group B）. The data of fractures treated between January 2010 and December 2011 in these hospitals were collected by the PACS system. The patients were categorized into 4 age groups： children （ 1 to 15 years old）, youth （16 to 44 years old）, middle-aged （45 to 59 years old）, and the aged （older than 60 years old）. The analytic items were gender, age and AO classification. The epidemiological characteristics of pelvic fractures were analyzed and compared between groups A and B. Results A total of 5, 065 pelvic fractures were included, involving 2, 531 males and 2,534 females with a male to female ratio of 1.00： 1. Age distribution showed that the peak age of pelvic fractures ranged from 41 to 50 years （22.80%） . AO type 61-A was the most common （85.19%） . The male to female ratio in group A （0.96：1 ） was insignificantly lower than in group B （1.04： 1） （ P 〉 0. 05）. The average age in group B （42. 0 ±17.9 years） was significantly younger than in group A （44. 6 ± 18.3 years） （ P 〈 0. 05）. The peak age was 41 to 50 years in both groups A and B, with a constitute ratio of 23.21% and of 22.33% respectively, showing a significant difference between groups （ P 〈 0.05）. The constitute ratios of youth, middle-aged and aged groups were significantly different between groups A and B （ P 〈 0. 05）. The most common fracture type was AO 61-A in both groups A and B, with a constitute ratio of 84. 45% and of 86.08% respectively. There were no significant differences between groups in the constitute ratios of AO types （ P 〈 0. 05） . Conclusions The middle and west areas had similar epidemiological features of pelvic fracture： numbers of male and female patients were nearly the same in the 2 areas; the peak age was from 41 to 50 years; the proportion of AO type 61-A was high. There were more female patients in the middle area, but more males patients in the west area. The average age in the middle area was larger than in the west area. There were differences between the 2 areas in the constitute ratios of age groups.
