Abstract
Gerrard P. Accuracy of self-reported physical activity as an indicator of cardiovascular
fitness depends on education level.
Objective
To determine whether there is a relationship between the level of education and the
accuracy of self-reported physical activity as a proxy measure of aerobic fitness.
Design
Data from the National Health and Nutrition Examination from the years 1999 to 2004
were used. Linear regression was performed for measured maximum oxygen consumption
(V̇o2max) versus self-reported physical activity for 5 different levels of education.
Setting
This was a national survey in the United States.
Participants
Participants included adults from the general U.S. population (N=3290).
Interventions
None.
Main Outcome Measure
Coefficients of determination obtained from models for each education level were used
to compare how well self-reported physical activity represents cardiovascular fitness.
These coefficients were the main outcome measure.
Results
Coefficients of determination for V̇o2max versus reported physical activity increased as the level of education increased.
Conclusions
In this preliminary study, self-reported physical activity is a better proxy measure
for aerobic fitness in highly educated individuals than in poorly educated individuals.
