Insights
Bed-sharing at six months is common, particularly with breastfeeding and sleep disturbances. Single parents are more likely to bed-share, while formula feeding in the first week is associated with less bed-sharing.
Area of Science:
- Pediatrics
- Public Health
- Sociology
Background:
- Sudden infant death syndrome (SIDS) risk is linked to bed-sharing, yet it remains a prevalent practice.
- Understanding factors associated with bed-sharing is crucial for infant safety guidelines.
Purpose of the Study:
- To investigate the prevalence of bed-sharing at six months of age.
- To identify demographic and behavioral factors associated with bed-sharing in infants.
Main Methods:
- A cohort of 8176 randomly selected families was invited to participate.
- A questionnaire was administered at six months of age, with 5605 families responding (68.5% response rate).
Main Results:
- 19.8% of families reported bed-sharing at six months.
- Breastfeeding at six months (OR 1.94) and frequent night awakenings (OR 2.70) were significantly associated with bed-sharing.
- Bed-sharing was more common in single-parent households (OR 2.04) and less common with early bottle-feeding (OR 0.70).
Conclusions:
- Breastfeeding and infant sleep problems are correlated with bed-sharing.
- Single parenthood is associated with increased bed-sharing.
- Early formula feeding shows a negative association with bed-sharing prevalence.
Aim:
In spite of several reports of an increased risk of sudden infant death syndrome (SIDS) in connection with bed-sharing, it is not an uncommon practice. The aim of this study was to examine bed-sharing at 6 months of age and the factors that are associated with bed-sharing.
Methods:
Our cohort comprised 8176 randomly chosen families. At 6 month of age, the families received an invitation to the study, with a questionnaire, which was completed by 5605 families (response rate 68.5%).
Results:
Of the families, 19.8% bed-shared. In the multivariate analysis, we found a correlation between breast-feeding and bed-sharing (breast-feeding at 6 months: OR 1.94; 95% CI 1.56, 2.41). Moreover, we found an association with 3+ nightly awakenings at 6 months (2.70; 2.20, 3.32). It was more common to share a bed if the parent was single (2.04; 1.19, 3.51) and less common if the infant was bottle-fed in the first week (0.70; 0.54, 0.90). Never using a pacifier was associated with a higher frequency of bed-sharing.
Conclusion:
We found a correlation between breast-feeding and bed-sharing as well as between sleeping problems and a single parent. A lower percentage of infants sleeping in the parental bed were seen in association with formula feeding in the first week after birth.
