Purpose: We examined total activity, light activity, and moderate-to-vigorous physical activity (MVPA) as predictors of mortality in a nationally representative sample of older adults. Then we explored the theoretical consequences of replacing sedentary time with the same duration of light activity or MVPA.
Methods: Using accelerometer-measured activity, the associations between total activity, light activity (100-2019 counts per minute), and MVPA (>2019 counts per minute) counts and mortality were examined in adults age 50 to 79 yr in the National Health and Nutrition Examination Survey, 2003-2006 (n = 3029), with mortality follow-up through December 2011.

Background: Increased prevalence of diabetes in the U.S. population could contribute substantially to increases in disability at older ages.

- The study analyzed diabetes prevalence trends in the U.S. from 1910 to 1989 using a sample of over 40,000 individuals.
- Findings reveal that age-adjusted diabetes prevalence nearly quintupled from those born in 1910-1919 to those born in 1980-1989, with rates increasing significantly with age within each cohort.
- The analysis showed that diabetes incidence is highest between ages 55-64, before declining in older age groups, suggesting that changes in birth cohorts played a major role in the rising prevalence over time.
