Sleep-Deprived Babies May Face Obesity Risk Later
Babies who don’t get enough sleep may end up weighing more later in childhood, according to a study by researchers at Massachusetts General Hospital. More from Time.com:
Plenty of studies connect poor sleep habits in adults to obesity, but few track the long term effect of infants’ sleep throughout childhood. That’s why Dr. Elsie Taveras, chief of general pediatrics at Massachusetts General Hospital for Children, and her colleagues followed babies every year from 6 months old until they were 7. At each visit, the team recorded height, weight, body fat, waist and hip circumference and sleep habit information to get the most complete picture yet of how sleep patterns are connected to childhood health.
Taveras rated the children’s sleep according to the recommended amounts for their age group set by the National Sleep Foundation and the National Heart, Lung and Blood Institute—for those under 2, that was more than 12 hours a day; for 3-4 year olds, that was more than 10 hours a day; and for kids 5 to 7, that was more than nine hours daily. At age 7, children with the lowest sleep scores throughout their young lives had the highest rates of obesity and body fat, specifically abdominal fat which other studies have linked to a higher risk of chronic conditions such as heart disease and diabetes.
What sets Taveras’ work apart is that it shows how consistently disrupted sleep throughout childhood can have a cumulative effect on health. “This lends more evidence to the fact that insufficient sleep has significant health implications,” she says.
Consistently skimping on shut-eye, especially at an early age, may interfere with appetite hormones that control how hungry and full we feel. And because sleep is an important time for the body’s metabolism to reset itself, sleep deprivation can also skew the body’s circadian clock, changing the body’s ability to burn calories from the diet and leading to higher blood sugar levels.
The researchers recommend that parents maximize their kids’ sleep with healthy practices including consistent bedtime routines, limiting stimulating food and drink–especially caffeine-containing beverages–and eliminating electronic devices like televisions or mobile devices from kids’ bedrooms.
