Abstract

PURPOSE:

To determine the utility of the Stanford Brief Activity Survey (SBAS) as a quick screening tool in a clinical population, where no other measure of physical activity was available.

METHODS:

The SBAS was administered to 500 younger cases in the Atherosclerotic Disease Vascular Function and Genetic Epidemiology (ADVANCE) study, a case-control genetic association study, between December 2001 and January 2004. Younger cases in the ADVANCE study included men (<46 years old) and women (<56 years old) diagnosed with early-onset coronary artery disease. Frequency distributions of the SBAS and associations between SBAS activity categories and selected cardiovascular disease risk factors by sex were calculated.

RESULTS:

Subjects were 45.9 +/- 6.4 years old, 68% married, 61% women, 51% white, and 21% college graduates. Clinical diagnoses for early-onset coronary artery disease included 61% myocardial infarction, 23% coronary revascularization procedure, and 16% angina pectoris. In women, associations between all cardiovascular disease risk factors examined across SBAS categories were statistically significant (P trend < .01). In men, the associations across SBAS categories were statistically significant (P trend < .01), except for body mass index (P trend = .065). Adjustment for body mass index, age, ethnicity, and education with interactions by sex did not change the results.

CONCLUSION:

Subjects in the higher SBAS activity categories had more favorable cardiovascular disease risk profiles than did their less active counterparts, regardless of sex. The SBAS can be recommended for use in clinical populations providing immediate feedback on current physical activity level.
