To examine the relationships between objectively measured sleep patterns
(sleep duration, sleep efficiency and bedtime) and sugar-sweetened beverage
(SSB) consumption (regular soft drinks, energy drinks, sports drinks and
fruit juice) among children from all inhabited continents of the world.
Multinational, cross-sectional study.
The International Study of Childhood Obesity, Lifestyle and the Environment
Children (n 5873) 9–11 years of age.
Sleep duration was 12 min per night shorter in children who reported
consuming regular soft drinks ‘at least once a day’
compared with those who reported consuming ‘never’ or
‘less than once a week’. Children were more likely to
sleep the recommended 9–11 h/night if they reported
lower regular soft drink consumption or higher sports drinks consumption.
Children who reported consuming energy drinks ‘once a week or
more’ reported a 25-min earlier bedtime than those who reported
never consuming energy drinks. Children who reported consuming sports drinks
‘2–4 d a week or more’ also reported a
25-min earlier bedtime compared with those who reported never consuming
sports drinks. The associations between sleep efficiency and SSB consumption
were not significant. Similar associations between sleep patterns and SSB
consumption were observed across all twelve study sites.
Shorter sleep duration was associated with higher intake of regular soft
drinks, while earlier bedtimes were associated with lower intake of regular
soft drinks and higher intake of energy drinks and sports drinks in this
international study of children. Future work is needed to establish
causality and to investigate underlying mechanisms.
