COLUMBIA, Md., March 10, 2014 /PRNewswire/ — Supplementation of long-chain omega-3s, and DHA (docosahexaenoic acid) in particular, were associated with seven fewer wake episodes and longer sleep duration – 58 minutes of more sleep per night – in a subset of children, according to a new study conducted at the University of Oxford in the United Kingdom. Additionally, higher blood levels of DHA may relate to better sleep among children based on parent-rated observations.

The paper titled, “Fatty acids and sleep in U.K. children: Subjective and pilot objective sleep results from the DOLAB study – a randomized controlled trial,” was recently published in the peer-reviewed Journal of Sleep Research. The randomized, placebo-controlled clinical trial and the observational analysis were a part of the independent study – DHA Oxford Learning and Behavior (DOLAB) study –initiated at the University of Oxford and funded by a grant from DSM Nutritional Products.

Intervention trial
The DOLAB randomized, placebo-controlled clinical trial explored whether 16-week supplementation of 600 mg of DHA from algae per day verses corn/soybean oil placebo may improve sleep in a subset of children (n=362) aged 7-9 years recruited from mainstream schools in Oxfordshire, U.K. who were underperforming in reading. Additionally, the lead investigators assessed sleep patterns objectively in a random subgroup of 43 children by actigraphy (a non-invasive method of monitoring rest and activity cycles) and via sleep diaries completed by the children’s parents. The following variables were measured by actigraphy over five nights:

  • Sleep onset and offset times;
  • Sleep duration in minutes;
  • Minutes awake between sleep onset and offset;
  • Sleep efficiency (total sleep time divided by time in bed);
  • Sleep latency (minutes needed to fall asleep);
  • Number of wakings after sleep onset.
