The percentages presented in this column represent column percentages and sum to 100 percent within each practice category. All other percentages presented are weighted row percentages and sum to 100 percent across the 3 bed sharing or breastfeeding categories.
For each sleep surface, the odds ratios compare the use of the specific surface vs. not using the specified item.
Co-sleepers allow infants to sleep on separate surface that is adjacent to adult bed.
Adj. OR denotes adjusted odds ratio; CI denotes confidence interval; RS denotes room share; BS denotes bed sharing; SR denotes separate room.
The odds ratios were adjusted for the following independent variables: geographic region, baby’s age and birth weight, parity, mother’s age, education, and race.
