OBJECTIVE: This study examines the extent to which insufficient sleep is associated with diet quality in students taking part in the Massachusetts Childhood Obesity Research Demonstration Project.
METHODS: Data were collected in Fall 2012 for all 4(th) and 7(th) grade children enrolled in public schools in two Massachusetts communities. During annual BMI screening, students completed a survey that assessed diet, physical activity, screen time, and sleep. Of the 2456 enrolled students, 1870 (76%) had complete survey data. Generalized estimating equations were used to examine associations between sleep duration and dietary outcomes (vegetables, fruit, 100% juice, juice drinks, soda, sugar-sweetened beverages and water), accounting for clustering by school. Models were adjusted for community, grade, race/ethnicity, gender, television in the bedroom, screen time, and physical activity.
RESULTS: In adjusted models, students who reported sleeping <10hours/day consumed soda more frequently (β=0.11, 95% CI:0.03, 0.20) and vegetables less frequently (β=-0.09, 95% CI:-0.18, -0.01) compared with students who reported ≥10hours/day. No significant associations were observed between sleep duration and fruit, 100% juice, juice drinks or water.
CONCLUSIONS: In this population, insufficient sleep duration was associated with more frequent soda and less frequent vegetable consumption. Longitudinal research is needed to further examine these relationships.
