BACKGROUND
Wisconsin has the highest Black infant mortality rate (IMR) in the nation.
OBJECTIVE
Evaluate factors associated with racial inequity in IMR in Wisconsin.
STUDY DESIGN
Births/deaths/IMR for Black and White infants from 2011 to 2016 were obtained from the Wisconsin Interactive Statistics on Health system, stratified by gestational age (GA), and compared using direct adjustment method. IMR were compared based on cause of death, maternal age, and education.
RESULTS
Crude and adjusted IMR was 13.7 and 9.1 for black infants. Respective IMR for white infants was 4.8 and 5.3. Crude IMR was 180% higher in Black infants. After controlling for GA, IMR among Black infants was 70% higher. In term Black infants, deaths due to sudden infant death syndrome (SIDS), accidents, and assaults were markedly high.
CONCLUSIONS
Higher IMR in Black infants was due to increased premature births and increased mortality among term infants. Potentially modifiable causes of death were SIDS, accidents, and assaults.
背景
威斯康星州的黑人婴儿死亡率（IMR）位居全美之首。
目的
评估与威斯康星州 IMR 种族不平等相关的因素。
研究设计
从威斯康星州互动健康系统中获取了 2011 年至 2016 年间黑人和白人婴儿的出生/死亡/IMR 数据，按胎龄（GA）分层，并使用直接调整法进行比较。根据死因、产妇年龄和教育程度比较 IMR。
结果
黑人婴儿的粗死亡率和调整后死亡率分别为 13.7 和 9.1。白人婴儿的相应死亡率分别为 4.8 和 5.3。黑人婴儿的粗死亡率高出 180%。在控制 GA 后，黑人婴儿的 IMR 高出 70%。在足月黑人婴儿中，由于婴儿猝死综合征（SIDS）、意外和袭击导致的死亡明显较高。
结论
黑人婴儿的 IMR 较高，是由于早产率增加和足月婴儿死亡率增加所致。潜在可改变的死因是 SIDS、意外和袭击。
