Do stay up till
2 am? That could be the reason you are fat
If your favourite novels are stealing that precious sleep time from you,
don’t be surprised if you have to start squeezing into your skinny jeans. A new
study from the Northwestern University suggests that among healthy adults with
habitual sleep duration of at least 6.5 hours, late sleep timing was associated
with higher fast food consumption and lower vegetable intake, particularly
among men, as well as lower physical activity. Results show that late sleep
timing is associated with lower body mass index and is not associated with
total caloric intake; however, it remains associated with poorer diet quality,
particularly fast food, vegetable and dairy intake.
‘Our results help us further understand how sleep timing
in addition to duration may affect obesity risk,’ said principal investigator
Kelly Glazer Baron, adding ‘It is possible that poor dietary behaviors may
predispose individuals with late sleep to increased risk of weight gain.’ The
study group consisted of 96 healthy adults between the ages of 18 and 50 years
with sleep duration of 6.5 hours or more. The study involved 7 days of wrist
actigraphy to measure sleep, food diaries to measure caloric intake and dietary
patterns, and SenseWear arm band monitoring to measure physical activity. Dim
light melatonin onset was evaluated in the clinical research unit. Body fat was
evaluated using dual axis absorptiometry (DXA). Data were analyzed using
correlation and regression analyses controlling for age, sex, sleep duration
and sleep efficiency.
The research appears in the journalSleep.
