Onset of ADL and IADL limitation among Chinese middle-aged and older adults.

ABSTRACT

It is important to measure the prevalence and onset of limitations for older adults to take critical day-to-day activities in the population. However, too often, only very older people are covered, and too few activities are included in the studies. Using a nationally representative sample from 2011 to 2018 (N = 16, 381), this study characterizes the limitation pattern covering ADL and IADL activities among middle-aged and older adults in China. We use survival models to characterize the limitation transition. We find that half of the population become limited in activities including housekeeping, toileting, managing money, and cooking in their early 70s, followed by shopping, bathing, transferring and dressing in their late 70s, continence, and taking medications in their early 80s, and feeding in their early 90s. In addition, women show significantly younger age of limitation onsets for all activities except continence.
