Total, early, and late fetal mortality rates were generally flat in the United States from 2006 through 2012. Over this same period, fetal mortality rates were also essentially unchanged among each of the three largest race and Hispanic origin groups: non-Hispanic white, non-Hispanic black, and Hispanic women. The perinatal mortality rate declined 4% from 2006 through 2011, a result of a decrease in early neonatal mortality. The perinatal mortality rate fell 8% for non- Hispanic black women; declines among non-Hispanic white and Hispanic women were not statistically significant. The continued decline in the perinatal mortality rate is noteworthy. The rate is down 10% since 2000 (4), and the pace of decline for the most current period, 2006–2011, is consistent with that for 2000–2005. The U.S. fetal mortality rate, however, did not improve during 2006–2012.
2006年至2012年期间，美国的总胎儿死亡率、早期胎儿死亡率和晚期胎儿死亡率总体持平。在同一时期，三个最大的种族和西班牙裔群体（非西班牙裔白人、非西班牙裔黑人以及西班牙裔女性）的胎儿死亡率也基本保持不变。围产期死亡率从2006年至2011年下降了4%，这是早期新生儿死亡率下降的结果。非西班牙裔黑人女性的围产期死亡率下降了8%；非西班牙裔白人和西班牙裔女性的围产期死亡率下降幅度在统计学上不显著。围产期死亡率的持续下降值得关注。自2000年以来，该比率下降了10%（4），2006 - 2011年最近时期的下降速度与2000 - 2005年一致。然而，2006 - 2012年期间美国的胎儿死亡率并未改善。
