“…Although SUID mortality has decreased overall in the United States since the mid-1990s, there has been little change in the number of deaths in the early neonatal period; thus, these deaths make up a larger percentage of total SUIDs. 5 The initial days of human life carry considerable risk, with death in the first week of life representing 73% of all deaths in the neonatal period (,28 days) worldwide. 6 Thus, this time window has been considered the most critical for a neonate.…”

OBJECTIVES: In most recent studies, authors combine all cases of sudden infant death syndrome, other deaths from ill-defined or unknown causes, and accidental suffocation and strangulation in bed as a single population to analyze sudden unexpected infant death (SUID). Our aim with this study is to determine if there are statistically different subcategories of SUID that are based on the age of death of an infant. METHODS: In this retrospective, cross-sectional analysis, we analyzed the Centers for Disease Control and Prevention Birth Cohort Linked Birth/Infant Death Data Set (2003-2013: 41 125 233 births and 37 624 SUIDs). Logistic regression models were developed to identify subpopulations of SUID cases by age of death, and we subsequently analyzed the effects of a set of covariates on each group. RESULTS: Two groups were identified: sudden unexpected early neonatal deaths (SUENDs; days 0-6) and postperinatal SUIDs (days 7-364). These groups significantly differed in the distributions of assigned International Classification of Diseases, 10th Revision code, live birth order, marital status, age of mother, birth weight, and gestational length compared to postperinatal SUIDs (days 7-364). Maternal smoking during pregnancy was not a significant risk factor for deaths that occurred in the first 48 hours. CONCLUSIONS: SUEND should be considered as a discrete entity from postperinatal SUID in future studies. These data could help improve the epidemiological understanding of SUEND and SUID and provide clues to a mechanistic understanding underlying the causes of death.

“…We tested the association of SIDS with these two stressors using prevalence data from 16 worldwide populations, 15 countries, and over 40 US states. This is the first ecological link study to test the association between SIDS and MNC, and it is done at a time that SIDS rates remain alarmingly high [27] two decades after the "Back to Sleep" (BTS) campaign.…”

Sudden Infant Death Syndrome (SIDS) is the most common cause of postneonatal infant death. The allostatic load hypothesis posits that SIDS is the result of perinatal cumulative painful, stressful, or traumatic exposures that tax neonatal regulatory systems. To test it, we explored the relationships between SIDS and two common stressors, male neonatal circumcision (MNC) and prematurity, using latitudinal data from 15 countries and over 40 US states during the years 1999-2016. We used linear regression analyses and likelihood ratio tests to calculate the association between SIDS and the stressors. SIDS prevalence was significantly and positively correlated with MNC and prematurity rates. MNC explained 14.2% of the variability of SIDS's male bias in the US, reminiscent of the Jewish myth of Lilith, the killer of infant males. Combined, the stressors increased the likelihood of SIDS. Ecological analyses are useful to generate hypotheses but cannot provide strong evidence of causality. Biological plausibility is provided by a growing body of experimental and clinical evidence linking adversary preterm and early-life events with SIDS. Together with historical evidence, our findings emphasize the necessity of cohort studies that consider these environmental stressors with the aim of improving the identification of at-risk infants and reducing infant mortality.

“…3 Of note, all five of the SUPC events occurred in the first 2 hours of postnatal life. 2 Bass et al 4 have shown that 29.2% of all neonatal cases occurred in the first week of postnatal life, which they defined as sudden unexpected infant death. 4 In some publications about SUPC, concern has been expressed about the safety of these newborn infants during their initial skin-to-skin and breastfeeding contacts with their exhausted, and in some cases, distracted mothers.…”

“…1,2,4 Bass et al 5 have demonstrated an associated increase percent in SUPC rates in Baby Friendly Hospitals in Germany, the United Kingdom, and Sweden. However, Bartick and Feldman-Winter, 6 in a letter to the editor in response to the article by Bass et al, 4 concluded "skin to skin care cannot be blamed for the increase in suffocation deaths." They suggested that the SUPC deaths in infants born at >35 weeks of gestation warrant further investigation and that, in the Swedish experience, an infant was found lifeless as the mother fell asleep during breast-feeding, another well-recognized SUPC risk factor.…”
