Joining Parents' Bed at Night and Overweight among 2- to 6-Year-Old Children - Results from the ‘Healthy Start' Randomized Intervention

Abstract

Objective: Parental and child co-sleeping has been suggested as a risk factor for short sleep duration and poor sleep quality that may lead to overweight. We examined if joining parent's bed during night was associated with child overweight. Methods: Cross-sectional data from the ‘Healthy Start' study including 635 2- to 6-year-old Danish children, who were all considered obesity prone. Of these, 496 children had complete information on BMI and whether the child joined parents' bed during night and if so, how frequently. International cut-offs for overweight according to age and gender were applied, and logistic regression was used to estimate odds ratio (OR) and 95% Confidence Intervals (CI). Analyses were adjusted for the child's age and gender, overall family stress, parental educational level, and parental BMI. Results: Children who did not join their parent's bed were more likely to be overweight compared to children who did (OR 1.75 (95% CI 0.99-3.10)). Children who rarely joined their parents' bed had OR 2.74 of being overweight (95% CI 1.01-7.44) compared to children who joined every night. Conclusion: Children who rarely joined parents' bed during night were almost three times more likely to be overweight than those who joined every night.

“…22 There are mixed studies on the association of co-sleeping and obesity; in a Danish study of 2-6 year old children, co-sleeping was associated with a decreased risk of overweight. 23 There is a need for more research into obesity risk for nighttime formula intake compared to nighttime breastmilk intake.…”

“…28 Numerous studies have also found associations between parenting styles and childhood obesity: authoritative styles are more protective than permissive. 22,23 Notably, controlling and permissive styles have been found in Hispanic families that may contribute to overfeeding. [29][30][31] Research into infant obesity prevention focuses on responsive feeding, recommending parents pay close attention to hunger and satiety cues, but limiting feeding at other times, i.e.…”

“…Co-sleeping varies by culture and was found to occur at a higher rate in Hispanic families compared to white families [ 27 ]. There are mixed studies on the association of co-sleeping and obesity; in a Danish study of 2–6 year old children, co-sleeping was associated with a decreased risk of overweight [ 28 ].…”
