The National Center for Health Statistics (NCHS) – an agency of the Centers for Disease Control and Prevention (CDC) – invites you to attend its 2010 National Conference on Health Statistics. The conference is FREE and will be held Monday through Wednesday, Aug. 16–18, 2010, at the Omni Shoreham Hotel in Washington, D.C. (This conference was previously called the Data Users Conference.) Of potential interest to sleep/circadian researchers, CDC/NCHS datasets include several sleep questions and an immense array of cross-cutting variables. Many of these relationships remain unanalyzed and unreported. Sessions fill up quickly, so the NCHS encourages you to register today.
