PUFA ω-3 and ω-6 Biomarkers and Sleep: A Pooled Analysis of Cohort Studies on Behalf of the Fatty Acids and Outcomes Research Consortium (FORCE)

In a pooling analysis of 12 studies from 5 countries, higher blood/tissue concentrations of very long chain omega-3 fatty acids (EPA + DPA + DHA and DHA alone) were associated with lower odds of long sleep duration. These findings highlight the importance of continued study of n-3 PUFAs given the public health implications of poor sleep.

Commercial Devices Provide Estimates of Energy Balance with Varying Degrees of Validity in Free-Living Adults

Interest in improving accuracy, and replacing self-reports with passive tools when estimating energy balance (EB) using intake (EI), storage (ES) and expenditure (EE)) has led to wide use of commercial devices e.g. Fitbits. A study with free-living adults looked at repeatability, and measurement error of these devices and showed varying degrees of validity when used to estimate EB compared to gold-standard techniques, with EE measures being the most robust and ES the poorest.

Opportunities and Challenges of Technology Tools in Dietary and Activity Assessment: Bridging Stakeholder Viewpoints

The science and tools of measuring energy intake and output in humans have rapidly advanced in the last decade. Engineered devices such as wearables and sensors, software applications, and Web-based tools are now ubiquitous in both research and consumer environments.
