Data_Sheet_1_Prevalence, Incidence, and External Causes of Traumatic Spinal Cord Injury in China: A Nationally Representative Cross-Sectional Survey.PDF

Background and PurposeThe epidemiological characteristics of traumatic spinal cord injury (TSCI) in China are unclear. Thus, we aimed to study prevalence, incidence, and external causes of TSCI in China nationwide.
MethodsIn 2013, we conducted a nationally representative, door-to-door epidemiological survey on TSCI in China using a complex, multistage, probability sampling design.
ResultsIn China, the point prevalence of TSCI standardized to the China census population 2010 was 569.7 (95% CI: 514.2–630.4) per 1,000,000 in the population, 753.6 (95% CI: 663.3–854.3) per 1,000,000 among men, and 387.7 (95% CI: 324.8–461.1) per 1,000,000 among women. The incidence of TSCI standardized to the China census population 2010 was 49.8 (95% CI: 34.4–70.7) per 1,000,000 per year in the population, 63.2 (95% CI: 38.9–98.5) per 1,000,000 among men, and 36.9 (95% CI: 19.5–65.9) per 1,000,000 among women. Among the 415 TSCI events in 394 prevalent cases, the top three injury causes were falls (55.2%), motor vehicle collisions (MVCs) (26.5%), and strike injuries (10.1%), while other injury causes including gunshot and explosion accounted for 8.2%. Among the 394 prevalent cases, the mean age of patients at the time of injury was 43.7 ± 17.1 years; the male-to-female ratio was 1.86:1.
ConclusionIt is estimated that there are 759,302 prevalent patients with TSCI in total and 66,374 new TSCI cases annually in China. Falls and MVCs are still 2 major external causes for TSCI in China.

研究背景与目的 目前我国创伤性脊髓损伤（traumatic spinal cord injury, TSCI）的流行病学特征尚不明确。为此，本研究旨在开展全国范围内的创伤性脊髓损伤流行率、发病率及损伤原因的相关研究。
方法 2013年，本研究采用复杂多阶段概率抽样设计，在全国范围内开展了针对创伤性脊髓损伤的入户流行病学调查。
结果 以2010年全国人口普查人口结构为标准进行标化后，我国创伤性脊髓损伤的时点患病率为569.7例/100万人（95%置信区间：514.2~630.4）；其中男性时点患病率为753.6例/100万人（95%置信区间：663.3~854.3），女性时点患病率为387.7例/100万人（95%置信区间：324.8~461.1）。标化后的创伤性脊髓损伤年发病率为49.8例/100万人（95%置信区间：34.4~70.7）；其中男性年发病率为63.2例/100万人（95%置信区间：38.9~98.5），女性年发病率为36.9例/100万人（95%置信区间：19.5~65.9）。在394名现症病例对应的415起创伤性脊髓损伤事件中，排名前三的损伤原因为跌倒（55.2%）、机动车碰撞（motor vehicle collisions, MVCs）（26.5%）及打击伤（10.1%）；其余损伤原因包括枪击与爆炸，占比8.2%。在394名现症病例中，患者受伤时的平均年龄为43.7±17.1岁，男女性别比为1.86:1。
结论 据估算，我国现有创伤性脊髓损伤患者总计759302例，每年新增创伤性脊髓损伤病例66374例。跌倒与机动车碰撞仍是我国创伤性脊髓损伤的两大主要外部致病原因。
