Leisure-time physical activity among US adults 60 or more years of age: results from NHANES 1999-2004.

Background: We examined leisure-time physical activity (LTPA) in US adults 60 or more years of age. After determining the prevalence of 3 levels of LTPA (no LTPA, <150 minutes LTPA/wk, and > or =150 minutes of LTPA/ wk), we examined the association of demographic variables and current health status with LTPA.

Methods: Self-reported LTPA was examined by gender, age, race/ethnicity, education, family poverty income ratio, marital status, and self-reported health. Multiple logistic regression methods were used in the adjusted model.

Results: Walking was the most frequently reported LTPA. Overall, 27% of adults achieved LTPA levels of 150 minutes or more per week. Male gender, younger age, non-Hispanic white race/ethnicity, higher education attainment, higher income status, being married, and excellent self-reported health were associated with higher LTPA. The prevalence of no LTPA (52.5%) exceeded the Healthy People 2010 objective target of 20%.

Conclusions: Our findings show that more than half of adults 60 or more years of age reported no LTPA and that levels of LTPA in the older population vary by demographic and health characteristics.
