New research reinforces the theory that there may be a connection between sleep deprivation and obesity in kids and teens.
For a paper recently published in the academic journal Sleep, researchers looked at data collected from 42 different studies involving 75,499 participants aged 0 to 18.
The researchers sorted the participants into two categories:
- Short sleepers, who got less than the recommended amount of nightly sleep for their age
- Regular sleepers, who got the recommended amount of nightly sleep for their age
The researchers found that kids in the short sleeping group gained more weight (regardless of their age) and were 58% more likely to become overweight or obese than their peers in the regular sleeper group.
“The results showed a consistent relationship across all ages indicating that the increased risk is present in both younger and older children,” researcher Dr. Michelle Miller told MedicalXpress.com. “The study also reinforces the concept that sleep deprivation is an important risk factor for obesity, detectable very early on in life.”
More Research Is Needed
It’s not clear exactly why sleep deprivation and obesity are linked, but experts have a few theories.
“Sleep-deprived people may be too tired to exercise, decreasing the “calories burned” side of the weight-change equation,” the Harvard Sleep website explains. “Or people who don’t get enough sleep may take in more calories than those who do, simply because they are awake longer and have more opportunities to eat; lack of sleep also disrupts the balance of key hormones that control appetite, so sleep-deprived people may be hungrier than those who get enough rest each night.”
According to the National Sleep Foundation, the recommended amount of sleep for different age groups is as follows:
- Newborns (aged 0-3 months) should sleep 14 to 17 hours each day.
- Infants (aged 4-11 months) should sleep 12 to 15 hours.
- Toddlers (aged 1-2 years) should sleep 11 to 14 hours.
- Preschoolers (aged 3-5) should sleep 10 to 13 hours.
- School-age children (aged 6-13) should sleep 9 to 11 hours.
- Teenagers (aged 14-17) should sleep 8 to 10 hours nightly.
