Values denote the relative increase in disability burden over the 6-month follow-up period for the two comparison groups. For each of these 13 activities, disability was defined as the need for personal assistance or unable to do. The number of disabilities overall and for each group of activities (basic, instrumental, mobility) were summed. Abbreviations: RR, relative risk; CI, confidence interval.
ADLs (activities of daily living) included bathing, dressing, walking across a room, and transferring from a chair.
IADLs (instrumental activities of daily living) included shopping, housework, meal preparation, taking medications, and managing finances.
Mobility activities included walking 0.40 km, climbing one flight of stairs, lifting and carrying 4.5 kg, and driving a car in the past month.
