BACKGROUND
Sleep deprivation adversely impacts cognitive
performance. A nutritious diet is one strategy that can prevent sleep
deprivation and its adverse effects. However, few data exist regarding
the influence of diet on sleep duration among adolescents. Hence, it is
important to assess whether dietary habits are linked to adequate sleep
among adolescents.
METHODS
The 2013 Youth Risk Behavior Survey data were used in the
analysis. Nationally representative samples of adolescents were
obtained using a 3‐stage cluster design. Selected survey items included
number of hours slept on a school night, fruit and vegetable intake,
soda and milk intake, breakfast consumption, and demographic variables.
Data were analyzed with SAS 9.4 using a logistic regression model.
RESULTS
Holding other variables constant, an increase in total
daily consumption of vegetables, milk, and breakfast increased the odds
of sleeping ≥8 hours among participants (p < .01). An increase in
daily soda intake decreased the odds of sleeping ≥8 hours among
participants (p < .01). Separate logistic models for males and
females yielded similar findings (p < .01).
CONCLUSIONS
Promoting healthy eating habits such as intake of
vegetables, milk, and breakfast consumption among adolescents may
increase their likelihood of getting adequate sleep.
