Bed Sharing and the Risk of Sudden Infant Death Syndrome: Can We Resolve the Debate?
ABSTRACT To conduct a meta-analysis on the relationship between bed sharing and sudden infant death syndrome (SIDS) risk.
Data from PubMed and Medline were searched for studies published after Jan 1, 1970. The search strategy included articles with the terms "sudden infant death syndrome," "sudden unexpected death," and "cot death" with "bed sharing" or "co-sleeping." To further specify the potential risk of bed sharing and SIDS, subgroup analyses were performed.
Eleven studies met inclusion criteria and were included in the final meta-analysis. The combined OR for SIDS in all bed sharing versus non-bed sharing infants was 2.89 (95% CI, 1.99-4.18). The risk was highest for infants of smoking mothers (OR, 6.27; 95% CI, 3.94-9.99), and infants <12 weeks old (OR, 10.37; 95% CI, 4.44-24.21).
Bed sharing is a risk factor for SIDS and is especially enhanced in smoking parents and in very young infants.

ABSTRACT: Early and prolonged skin-to-skin contact (SSC) after birth between a mother and her newborn has been shown to generate beneficial effects on the mother-infant relationship and breastfeeding. Close mother-infant body contact immediately after birth positively enhances exclusive breastfeeding during the hospital stay, with a dose-response relationship. Skin-to-skin contact may ease the infant's transition to extra-uterine life and helps regulate the infant's body temperature and nursing behavior. However, reports of sudden unexpected postnatal collapse (SUPC) soon after birth, in healthy term neonates, in association with SSC, have raised concerns about the safety of this practice. Based on available evidence, we developed a surveillance protocol in the delivery room and postnatal ward of the Institute for Maternal and Child Health of Trieste (Italy). The aim of our protocol is (a) to promote safe mother and infant bonding and (b) to establish successful breastfeeding, without increasing the risk of SUPC. As there is no known effective intervention to prevent SUPC, our protocol has been conceived as a potential best practice.Journal of Human Lactation 10/2014; 31(1).

ABSTRACT: Evidence-based policy making often has a direct or indirect goal of promoting family resilience. The authors consider the ways in which scholarly disagreements about evidence can challenge this goal, focusing on the debate regarding whether adult–infant bedsharing increases the risk of infant mortality. A central issue is whether scholars conclude that public policy should recommend against all bedsharing or only bedsharing in particular risky circumstances. The authors use context-based evidence-based policy making (Dobrow, Goel & Upshur, 2004) as a framework for a review of studies of sudden infant death syndrome (SIDS) correlates and SIDS mechanisms related to bedsharing as well as the reasons parents bed share. The authors discuss the implications of different interpretations of the evidence and point to the potential of adversarial collaboration in helping to address the points of disagreement and ultimately better support family resilience. The issues discussed in this case are broadly relevant to other debated evidence for family policy making.Family Relations 02/2015; 64(1). DOI:10.1111/fare.12099 · 0.68 Impact Factor

ABSTRACT: For much of human history infant survival has been largely predicated by close and continuous contact between the infant and the primary carer–almost always the mother.Many factors in post-industrial human society - notably tobacco smoking, alcohol intake and the use of recreational drugs–have been associated with increased risk to infants sleeping in close proximity to their mothers. This is particularly true for mothers who choose not to breastfeed.The question of the risks and possible benefits of bed-sharing for mothers who plan to breastfeed, do not smoke, do not drink alcohol or take recreational drugs, and are aware of how to ensure a safe infant sleep environment need to be quantified.In this paper we review the evidence from several epidemiological studies and identify the factors that make bedsharing more or less hazardous for the infant. This analysis is important in allowing us to give parents accurate and unbiased information on which to make their own choices about optimal night time care of their infants without demonising normal parental behaviour or practices.Paediatric respiratory reviews 11/2014; DOI:10.1016/j.prrv.2014.10.008 · 2.22 Impact Factor
