Changing Impact of Obesity on Active Life Expectancy of Older Americans.

ABSTRACT:

Background

The rise in the number and earlier age of onset of obese persons has raised critical concerns about consequences of obesity; however, recent evidence suggests that the impact of obesity on health outcomes may have changed. This study aims to assess the change of the impact of obesity on active life expectancy among Americans aged 70 years and older over almost two decades, 1993-1998 to 2010-2014.

Methods

For each period, we use three waves of data from the Health and Retirement Study to estimate age-specific transition probabilities between health states. The average number of years active and disabled is calculated with Interpolated Markov Chain software based on estimated transition probabilities.

Results

Overall obesity and severe obesity increased marke
