Objective: This study aims to assess the relationship between sleep duration and overweight or obesity in very young, preschool, children aged 4 to 24 months involved in the GECKO Drenthe-cohort. Furthermore, we assessed the relationship between the use of a pacifier and co-sleeping (parental or with siblings) and the sleep duration. Design: Cross-sectional and longitudinal analyses with repeated monthly measures in a birth cohort. Measurements: A total of 919 Dutch children aged 4 and 24 months from the GECKO-cohort were included in the study of the effect of sleep on weight. 393 children had complete questionnaires regarding information about pacifier use at all timepoints (1, 2, 11, 14 and 18 months) and were participated in the study for the effect of a pacifier on sleep and 807 children were included in the analyses for the effect of co-sleeping with parents or siblings study. Body weight (gr.) and body height (cm.) were measured at the different ages, as well as waist circumference (cm.). A questionnaire about sleeping habits of the children and their environment was given to the parents during clinical visits or by GECKO Drenthe and send back to GECKO Drenthe when completed. Sleep was classified in minutes in a continuous and a categorical variable. The main outcome measure was weight, defined as the z-score for weight-for-length and the z-score for waist circumference. Possible confounders sex, age, birth weight and socioeconomic status participated in the different models. A lineair regression analyses was used to examine the different associations. Results: Sleep duration at 24 months decreased from 14.7 hours at 4 months of age to 11.8 hours. This was a significant difference (p<0,001). After adjustment for multiple confounders there was no significant association found, neither cross-sectional (at ages 4 and 24 months) nor longitudinal (at 24 months), between sleep duration and weight. There was however an association found between the use of a pacifier and the sleep duration. Each additional hour of the use of a pacifier was found to be associated with an increase over an hour of the sleep duration (p=0.040). There was no significant effect found between co-sleeping and the sleep duration. Conclusion: The present study did not find a significant association between sleep duration and weight in children aged 4 months to 24 months. Although a single correlation was significant, there were no consistent findings that supported the association between pacifier use and sleep duration. There was also no association found between co-sleeping and sleep duration.
