Each year, approximately 3500 infants in the United States die from sleep-related deaths. The number of sleep-related infant deaths has decreased overall since the 1990s, but disparities in sleep-related deaths persist among different populations. The purpose of this study was to determine the most common risk factors and locations in Cook County, Illinois for sleep-related deaths in infants under 6 months of age.
We conducted a retrospective study among infants less than 6 months of age who died in Cook County, Illinois in 2015 and 2016, in which the manner of death was of undetermined intent with at least one modifiable sleeping risk factor present, as reported by the medical examiner. Data were obtained from the Illinois Violent Death Reporting System (IVDRS), a state-based, anonymous, surveillance system. County trends and circumstances of the deaths were also evaluated. Frequencies, percentages, and Chi-square analysis were used to describe and characterize these deaths.
In Cook County in 2015 and 2016, 116 infants less than 6 months of age died where the manner of death was classified as undetermined intent. The median age of death was 2 months. Of these deaths, 63 (54.3%) of the infants were boys. African-American and Hispanic infants comprised 71 (65.7%) and 23 (21.3%) of the deaths, respectively. In 84 (72.4%) of the cases, at least one known sleeping risk factor was present and 56 (66.7%) of the infants who died with a known sleeping risk factor were co-sleeping. Notably, 33 (29.7%) of the deaths in Cook County were clustered within six zip codes.
The majority of infants who died unexpectedly in Cook County in 2015 and 2016 did so in the presence of sleeping risk factors, with co-sleeping being the most common. African-American infants, infants under 2 months of age, and several geographical areas within Chicago appear to be at increased risk. Interventions to target these preventable causes in the populations at increased risk should be instituted to prevent future deaths.
在美国，每年约有3500名婴儿死于与睡眠相关的死亡。自20世纪90年代以来，与睡眠相关的婴儿死亡总数有所下降，但不同人群之间与睡眠相关的死亡差异仍然存在。本研究的目的是确定伊利诺伊州库克县6个月以下婴儿与睡眠相关死亡的最常见风险因素和地点。
我们对2015年和2016年在伊利诺伊州库克县死亡的6个月以下婴儿进行了一项回顾性研究，这些婴儿的死亡方式意图不明，且存在至少一个可改变的睡眠风险因素，这是由法医报告的。数据来自伊利诺伊州暴力死亡报告系统（IVDRS），这是一个基于州的匿名监测系统。还评估了该县的死亡趋势和情况。使用频率、百分比和卡方分析来描述和表征这些死亡情况。
2015年和2016年在库克县，116名6个月以下婴儿死亡，其死亡方式被归类为意图不明。死亡的中位年龄为2个月。在这些死亡案例中，63名（54.3%）婴儿为男孩。非裔美国婴儿和西班牙裔婴儿分别占死亡案例的71例（65.7%）和23例（21.3%）。在84例（72.4%）案例中，存在至少一个已知的睡眠风险因素，在有已知睡眠风险因素死亡的婴儿中，56例（66.7%）是与他人同睡。值得注意的是，库克县33例（29.7%）死亡案例集中在六个邮政编码区域内。
2015年和2016年在库克县意外死亡的大多数婴儿是在存在睡眠风险因素的情况下死亡的，其中与他人同睡最为常见。非裔美国婴儿、2个月以下婴儿以及芝加哥的几个地理区域似乎风险更高。应针对这些高风险人群中这些可预防的原因采取干预措施，以防止未来的死亡。
