Both short and long sleeping times predict an increased risk of future body weight and fat gain in adults, according to a study published in the April 1 issue of the journal Sleep.
The study from Laval University in Quebec, Canada, focused on 276 adults between 21-64 years of age, whose body composition measurements and self-reported sleep duration were determined. Changes in fatty indices were compared between short (five to six hours), average (seven to eight hours) and long (nine to 10 hours) duration sleeper groups.
According to the results, short duration sleepers gained 1.98 kg (4.3 lb) more and long duration sleepers gained 1.58 kg (3.5 lb) more than did average duration sleepers over six years.
Short and long duration sleepers were 35 percent and 25 percent more likely to experience a 5 kg (11 lb) weight gain, respectively, as compared with average duration sleepers over six years.
The risk of developing obesity was higher for short and long duration sleepers as compared with average duration sleepers, with 27 percent and 21 percent increases in risk, respectively.
The researchers point out that these results emphasize the need to add sleep duration to the list of environmental factors that contribute to weight gain and obesity.
It is recommended that adults get between 7 and 8 hours of nightly sleep.
