The reported P-value is for a chi-square or t-test for a significant difference in proportion or mean between years, after adjusting for the age and sex differences across the two cohorts.
ADLs indicates Activities of Daily Living (eating, transferring, toileting, dressing, bathing, and walking across a room).
IADLs indicates Instrumental Activities of Daily Living (preparing meals, grocery shopping, making phone calls, taking medications, managing money).
Values in parentheses are weighted percentages derived using the HRS sampling weights to adjust for the complex design of the HRS survey. Weighted percentages for the 2012 sample are age- and sex-standardized to the 2000 sample using direct standardization.
P<0.05 for difference between 2000 and 2012.
P<0.001 for difference between 2000 and 2012.
