Trends and Factors Associated With Infant Bed Sharing, 1993-2010

Trends and Factors Associated With Infant Bed Sharing, 1993-2010 ImportanceA strong association between infant bed sharing and sudden infant death syndrome or unintentional sleep-related death in infants has been established. Occurrences of unintentional sleep-related deaths among infants appear to be increasing. ObjectivesTo determine the trends and factors associated with infant bed sharing from 1993 through 2010, including the association of physician advice on bed sharing. DesignNational Infant Sleep Position study conducted with annual telephone surveys. SettingThe 48 contiguous states.

Main Outcomes and MeasuresInfant bed sharing as a usual practice. ResultsOf 18 986 participants, 11.2% reported an infant sharing a bed as a usual practice. Bed sharing increased from 1993 (6.5%) to 2010 (13.5%).

Abstract

ImportanceA strong association between infant bed sharing and sudden infant death syndrome or unintentional sleep-related death in infants has been established. Occurrences of unintentional sleep-related deaths among infants appear to be increasing. ObjectivesTo determine the trends and factors associated with infant bed sharing from 1993 through 2010, including the association of physician advice on bed sharing. DesignNational Infant Sleep Position study conducted with annual telephone surveys. SettingThe 48 contiguous states. ParticipantsNighttime caregivers of infants born within 7 months of each survey administration. Approximately 1000 interviews were completed annually. Main Outcomes and MeasuresInfant bed sharing as a usual practice. ResultsOf 18 986 participants, 11.2% reported an infant sharing a bed as a usual practice. Bed sharing increased from 1993 (6.5%) to 2010 (13.5%). Although bed sharing increased significantly among white respondents from 1993 to 2000 (P < .001), the increase from 2001 to 2010 was not significant (P = .48). Black and Hispanic respondents reported an increase in bed sharing throughout the study period, with no difference between the earlier and later periods (P = .63 and P = .77, respectively). After accounting for the study year, factors associated with increase in infant bed sharing as a usual practice included maternal educational level of less than high school compared with college or greater (adjusted odds ratio, 1.42 [95% CI, 1.12-1.79]); black (3.47 [2.97-4.05]), Hispanic (1.33 [1.10-1.61]), and other (2.46 [2.03-2.97]) maternal race or ethnicity compared with white race; household income of less than $20 000 (1.69 [1.44-1.99]) and $20 000 to $50 000 (1.29 [1.14-1.45]) compared with greater than $50 000; living in the West (1.61 [1.38-1.88]) or the South (1.47 [1.30-1.66]) compared with the Midwest; infants younger than 8 weeks (1.45 [1.21-1.73]) or ages 8 to 15 weeks (1.31 [1.17-1.45]) compared with 16 weeks or older; and being born prematurely compared with full-term (1.41 [1.22-1.62]).
