Use of previous-day recalls of physical activity and sedentary behavior in epidemiologic studies: results from four instruments
For this study, we propose to utilize ACT24 previous-day recall data, which consists of up to 6 recalls collected over 12-months (one recall every other month) and participant demographic information.
Using ACT24 data we will describe participant characteristics and the amount of time reported overall in each of the main time-use categories, and for time spent in sleep (in-bed), physical activity and sedentary behavior. The broad time-use categories will include: personal care, paid work, household chores/caring, transportation, and leisure-time. We will describe the sedentary and physical active time and energy expenditure by activity intensity and time-use categories.
The primary goal of this project is to illustrate the methods and present descriptive results for these instruments recall instruments rather than to make explicit quantitative comparisons between the populations in which the tools were administered. Additionally, help identify areas for possible methodological improvements in the future we will also describe the similarities and differences between instruments and their scoring methods.
