This study sought to examine the incidence of sudden death in a large, multiethnic cohort of young women. Approximately 852,300 women entered basic military training from 1977 to 2001. During this period, there were 15 sudden deaths in female recruits (median age 19 years, 73% African-American), occurring at a median of 25 days after arrival for training. Of the sudden deaths, 13 (81%) were due to reasons that may have been cardiac in origin. Presumed arrhythmic sudden death in the setting of a structurally normal heart was seen in 8 recruits (53%), and anomalous coronary origins were found in 2 recruits (13%). The mortality rate was 11.4 deaths per 100,000 recruit-years (95% confidence interval 6.9 to 18.9). The rate was significantly higher for African-American female recruits (risk ratio 10.2, p <0.001). Sudden death with a structurally normal heart was the leading cause of death in female recruits during military training.
本研究旨在调查一个大型多民族年轻女性队列中的猝死发生率。1977年至2001年期间，约852,300名女性进入基础军事训练。在此期间，女性新兵中有15例猝死（中位年龄19岁，73%为非裔美国人），发生在到达训练基地后的中位25天。在这些猝死中，13例（81%）原因可能源于心脏。8名新兵（53%）出现了结构正常心脏情况下的推测性心律失常性猝死，2名新兵（13%）发现了冠状动脉起源异常。死亡率为每100,000新兵年11.4例死亡（95%置信区间6.9至18.9）。非裔美国女性新兵的死亡率显著更高（风险比10.2，p<0.001）。心脏结构正常的猝死是军事训练期间女性新兵的主要死因。
