“…Medical geriatricians and those studying antiaging strategies may see aging-related disability as a thing to be prevented, ameliorated, or cured (Hou et al, 2018; Manayi, Saeidnia, Gohari, & Abdollahi, 2014) and, thereby, talk about disability in terms of loss or decline. Social gerontologists, on the contrary, are more likely to describe disability in terms of social and cultural barriers to access and participation (Tinker, Hussain, D’Cruz, Tai, & Zaidman, 2016) and emphasize the need for supports. Policy and health services researchers in both fields are often limited by what is available in health care claims data and national surveys and may define disability in terms of types that merge impairments and restrictions (e.g., hearing, vision, cognition, and mobility [Okoro, Hollis, Cyrus, & Griffin-Blake, 2018]) or a combination of proxies of disability (e.g., self-reported restrictions and use of adaptive equipment [Fan, Strine, Jiles, Berry, & Mokdad, 2009]).…”
