BACKGROUND: Recent cross-sectional studies found higher consumption of energy-dense foods among children with short sleep duration; however, longitudinal studies examining changes in sleep and diet over time are needed.

OBJECTIVE: This study aimed to investigate prospective associations between changes in objectively measured sleep duration and alterations in proposed dietary risk factors for obesity in 8-11-year-old Danish children.

METHODS: Four hundred forty-one children recorded dietary intake during seven consecutive days, along with accelerometer measurements estimating sleep duration at baseline and after ∼200 days.

RESULTS: Baseline sleep duration did not predict changes in dietary intake or vice versa (all P ≥ 0.69). However, 1-h lower sleep duration was associated with higher intake of added sugar (1.59 E%; P = 0.001) and sugar-sweetened beverages (0.90 E%; P = 0.002) after 200 days with no change in energy density of the diet (P = 0.78).

CONCLUSION: Our results suggest that a negative change in sleep duration is associated with higher intakes of sugar containing foods/beverages.
