Abstract
Objective
The current study examined school-summer differences in children's sleep patterns
and sleep hygiene. Cross-sectional relationships with children's sleep, sleep hygiene,
and weight status were explored during the school year and summer.
Methods
Children (5-8 years) and their parents (n = 197 dyads) were recruited from 4 schools in southeastern Texas and via Facebook.
Parents reported children's school year and summer sleep, sleep hygiene, and screen
media use. Children's body mass index (BMI) was objectively assessed at the beginning
and end of the summer. Associations between children's sleep hygiene and screen media
use, sleep duration, and weight status were explored.
Results
Children's sleep midpoint was earlier during the school year (1:54 AM ± 0.03) than
in the summer (2:06 AM ± 0.03; t = 4.07, p < .0001). During summer, children increased their screen media use by 38 minutes
(t = 2.32, p = .023) and decreased their caffeine intake from 7.43 to 7.0 (with scores ranging
from 3 to 15; t = 2.83, p = .006). Greater sleep-inhibiting (β = 0.40, p = .011) and fewer sleep-promoting (β = −0.28, p = .049) behaviors during the school year were associated with having a higher BMI.
There were no associations among sleep patterns, sleep hygiene and BMI during summer.
Conclusions
More positive school year sleep hygiene behaviors were supportive of having a healthier
weight status. Changes in these behaviors during the summer did not portend worse
weight outcomes. Supporting families in the establishment of sleep-promoting behaviors,
particularly during the school year may help address the child obesity epidemic.
