Abstract

Sudden infant death syndrome (SIDS) is the leading cause of death among infants aged 1 to 12 months. In this article, we review risk factors that may predispose infants to increased vulnerability. Maternal characteristics, including nonmodifiable and modifiable factors, antenatal medical conditions, labor and delivery events, and infant characteristics, are reviewed, with the purpose of helping obstetric care providers target risk reduction efforts. We have reviewed over 85 case–control, retrospective, and prospective cohort studies published between 1975 and 2011. Major modifiable risk factors include maternal and paternal smoking, drug use, alcohol use, and insufficient prenatal care. Infants at increased risk include males, premature infants, infants of low birth weight or growth-restricted infants, and infants in multiple gestations. By targeting modifiable and nonmodifiable risk factors, it may be possible to decrease the incidence of SIDS. Efforts should be put on decreasing high-risk behaviors and encouraging sufficient antenatal follow-up. In view of recent increases in ethnic and social disparity with SIDS, it is essential that risk reduction guidelines, which have recently been expanded by the American Association of Pediatrics, be explained in a culturally sensitive manner.
