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.<\/jats:p>\n               <\/jats:sec>\n               <jats:sec>\n                  <jats:title>METHODS:<\/jats:title>\n                  <jats:p>In this retrospective, cross-sectional analysis, we analyzed the Centers for Disease Control and Prevention Birth Cohort Linked Birth\/Infant Death Data Set (2003\u20132013: 41\u2009125\u2009233 births and 37\u2009624 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.<\/jats:p>\n               <\/jats:sec>\n               <jats:sec>\n                  <jats:title>RESULTS:<\/jats:title>\n                  <jats:p>Two groups were identified: sudden unexpected early neonatal deaths (SUENDs; days 0\u20136) and postperinatal SUIDs (days 7\u2013364). 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\u2013364). Maternal smoking during pregnancy was not a significant risk factor for deaths that occurred in the first 48 hours.<\/jats:p>\n               <\/jats:sec>\n               <jats:sec>\n                  <jats:title>CONCLUSIONS:<\/jats:title>\n                  <jats:p>SUEND should be considered as a discrete entity from postperinatal SUID in future studies.
