Introduction

Short sleep duration and/or poor sleep quality in childhood have been associated with later poorer health outcomes. Breastfeeding has been associated with frequent night waking and inconsistently with short sleep durations up to 18 months. Besides mothers may introduce complementary feeding before the recommended age when children presented sleep troubles.
We aimed to study the relations between infant feeding practices up to 8 months and child’s sleep characteristics (i.e. sleep onset difficulties, night waking, and night sleep duration) between 2 and 5-6 years old in the EDEN French birth-cohort.

Materials and methods

Analyses were based on 1034 children from the EDEN cohort with complete data collected prospectively through dietary records (at 4 and 8 months) and questionnaires assessing night-feeding, breastfeeding duration, age at complementary feeding introduction, night sleep duration, frequent sleep onset difficulties and frequent night waking. Frequent sleep onset difficulties and frequent night waking were defined as occurring each other night or more. Sleep trajectories between 2 and 5-6 years old were identified for sleep onset difficulties, frequent night waking and night-sleep duration by group-based trajectory modeling. For each sleep characteristic, children were attributed to the trajectory with the highest probability to belong to. The relations between sleep trajectories and early infant feeding practices were analyzed through multivariate logistic regressions adjusted for main familial, maternal and child’s factors.

Results

Two trajectories between 2 and 5-6 years old were identified for sleep onset difficulties and night waking (1. Rare and 2. Persistent (representing 26% and 22% of the children, respectively)), and 5 trajectories were identified for night sleep duration (1. Short (<10h30, 5% of the children), 2. Medium-low (10h30-11h, 48%), 3. Medium-high ≈11h30, 37%), 4. Long (≥11h30, 4%) and 5. Changing (i.e. 4 then 2, 6%)). Multivariate models showed that predominant breastfeeding >4 months was associated with the persistent sleep onset difficulties trajectory (OR [95% CI]=0.6 [0.3; 1.0]) as well as night-feeding between 4 and 8 months and at 2 years (OR [95% CI]=2.0 [1.3; 3.0] and OR [95% CI]=1.6 [1.1; 2.2], respectively). Night feeding at age 2 was also associated with the changing night-sleep duration trajectory (OR [95% CI]=2.4 [1.3; 4.3]). No significant associations were observed with night waking trajectories.

Conclusions

Results showed that some night-feeding practices during infancy were related to persistent sleep troubles among preschoolers. These practices are accessible to prevention.
