A new study has said 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. The study was conducted by researchers from the Northwestern University, and was published in the journal Sleep.
According to results of the study, 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.
Say the researchers, Our results help us further understand how sleep timing in addition to duration may affect obesity risk. It is possible that poor dietary behaviours may predispose individuals with late sleep to increased risk of weight gain.
the researchers studied 96 healthy adults aged between 18 and 50 years. They all had a sleep duration of 6.5 hours or more. The study lasted for 7 days. Sleep was measured using wrist actigraphy. Caloric intake and dietary patterns were noted through food diaries. Physical activity was measured using a SenseWear arm band. Dim light melatonin onset was evaluated in the clinical research unit. Body fat was evaluated using dual axis absorptiometry (DXA). Data were analysed using correlation and regression analyses controlling for age, sex, sleep duration and sleep efficiency.
