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

2014-08-27 03:12:09 | BioPortfolio

Summary

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.

Description

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.

NCI has been developing two web-based instruments, an automated self-administered 24-hour dietary recall (ASA24) and a physical activity 24-hour recall (ACT24), which can be administered several times over a year. Although these two instruments have the potential to qualitatively improve exposure assessment (at relatively low cost), they need to be evaluated for feasibility before being incorporated in cohorts on a large scale. Therefore, we propose to test ASA24 and ACT24 among AARP members aged 50 years and over to evaluate technical problems, determine response rates, and estimate the range of dietary intake and physical activity. In addition, we propose to include in this feasibility study two web-based versions of conventional questionnaires (lifestyle and medical history questionnaire and diet history questionnaire) as well as two software systems needed to conduct a web-based study (the automated Study Management System and Web Survey Management System). We will initially target 15,000 AARP members, expecting that approximately 2,000 individuals will agree to participate in the study and about 1,250 participants will complete ASA24 and ACT24 twice.

These web-based instruments and accompanying system tools represent a novel approach to carrying out diet and lifestyle research. The computerized, web-based study method can be applied to any observational study, large or small, case-control or cohort, as well as randomized controlled trials. This feasibility study will provide an opportunity to assess the feasibility of constructing large web-based cohort studies and characterize potential participants.

Medical and Biotech [MESH] Definitions

A diet that contains limited amounts of CARBOHYDRATES. This is in distinction to a regular DIET.

Regular course of eating and drinking adopted by a person or animal. This does not include DIET THERAPY, a specific diet prescribed in the treatment of a disease.

A diet that contains limited amounts of fat with less than 30% of calories from all fats and less than 10% from saturated fat. Such a diet is used in control of HYPERLIPIDEMIAS. (From Bondy et al, Metabolic Control and Disease, 8th ed, pp468-70; Dorland, 27th ed)

A diet which is devoid of GLUTENS from WHEAT; BARLEY; RYE; and other wheat-related varieties. The diet is designed to reduce exposure to those proteins in gluten that trigger INFLAMMATION of the small intestinal mucosa in patients with CELIAC DISEASE.

A course of food intake that is high in FATS and low in CARBOHYDRATES. This diet provides sufficient PROTEINS for growth but insufficient amount of carbohydrates for the energy needs of the body. A ketogenic diet generates 80-90% of caloric requirements from fats and the remainder from proteins.
