The Doubly Labeled Water (DLW) Database is a collection of over 7,000 measurements of daily energy expenditure made using the DLW technique, an extensively validated form of indirect calorimetry that uses stable isotopes of hydrogen and oxygen to track the body's production of carbon dioxide. The database includes measurements from 29 countries around the globe, from preterm infants to men and women in their 90's. Data have been contributed by DLW laboratories around the world and are cross-checked and recalculated using a validated equation to maximize accuracy and reliability. Standard variables, such as height, weight, and age, as well as water turnover, body composition, and health status, are available for most subjects. The database is hosted by the International Atomic Energy Agency.
The DLW Database is free to use. Researchers interested in using the database are encouraged to contact the management group to discuss their proposed project.
Financial Support for the DLW database is provided by the Taiyo Nippon Sanso Corporation, the Sercon Corporation, and the U.S. National Science Foundation [BCS-1824466].
