Objective: To investigate the prevalence and factors associated with co-sleeping and nighttime waking among the children of the Pelotas 2004 cohort at 12 months of age. Methods: All children born in the city of Pelotas, RS, Brazil during 2004 were enrolled on a longitudinal study. Mothers were interviewed at delivery and once more at 12 months of age to obtain information on their sociodemographic and reproductive characteristics and on their children's sleep and the environment in which their children sleep. Co-sleeping was defined as habitually sharing the bed with another person. Multivariate analysis was performed using Poisson regression. Results: The prevalence of co-sleeping at 12 months was 45.8% (95%CI 44.2-47.3). Co-sleeping was more common among mothers with low socioeconomic status, less education, younger mothers, mothers with more previous births and among children who wake at night. The prevalence of nighttime waking was 46.1% (95%CI 44.6-47.7). Nighttime waking was more common among boys and among the offspring of mothers who had had a greater number of previous pregnancies and of mothers who had been employed while pregnant. Conclusion: Co-sleeping and nighttime waking are common among this study population, indicating a need to continue follow-up in order to observe how long these habits persist through childhood and to investigate their consequences for child development and behavior.
