Disparities in data on Healthy People 2010 physical activity objectives collected by accelerometry and self-report

Am J Public Health. 2010 Apr 1;100 Suppl 1(Suppl 1):S263-8. doi: 10.2105/AJPH.2009.180075. Epub 2010 Feb 10.


Objectives: We compared findings on physical activity from national accelerometry data and Healthy People 2010 self-report data to identify differences in disparities by sociodemographic characteristics, gender, age, race/ethnicity, education level, and disability status.

Methods: Data were from the 2003 to 2004 National Health and Nutrition Examination Survey's accelerometry and the Healthy People 2010 Midcourse Review. We computed prevalence of inactivity and regular moderate- and vigorous-intensity movement according to Healthy People 2010 operational definitions.

Results: Mexican American adults were more active than non-Hispanic Blacks and Whites, and groups defined by race/ethnicity and educational attainment were more similar in physical activity in accelerometer than in self-report data. Disparities by gender and disability status were consistent with Healthy People 2010.

Conclusions: Disparities in physical activity differ from previous findings. Increased understanding of these disparities should be used to design better and more cost-effective physical activity interventions. Physical activity surveillance methods should be revised to make use of data collection methods that are more valid than self-report.
