Feasibility Study of a Web-Based Automated Self-Administered 24-hour Dietary Recall (ASA 24) and a Physical Activity 24-hour Recall

Completed

Conditions studied: Cancer

In brief

In spite of long-standing hypothesis relating diet and physical activity to several cancers, diet and physical activity-cancer associations have been modest at best and often inconsistent in epidemiologic studies. Investigators around the world have become increasingly concerned that error in the measurement of both diet and physical activity is compromising our ability to detect these important but modest associations. Most commonly used diet and physical activity assessment methods have been based on a relatively small set of questions (e.g. 124 food items consumed or 5-10 physical activities in the past 12 months). Recent developments in computer technology provide an opportunity to use internet-based instruments to assess an individual s diet and physical activity more accurately and cost effectively.
