We calculated the FI at each of the eight waves used in our analysis.Modelling individual social risks and frailtyIn the first stage of the analysis, we identified social risks that may contribute to precarity and tested whether they were associated with frailty.；For risks relating to employment, such as job loss, measures referred to whether the respondent had ever experienced such an event either at the current or previous ELSA waves (or as reported in the life-history module for certain variables).；For similar reasons, risks relating to care-giving also referred to whether the respondent had ever reported such risks at the current or previous ELSA waves.
方法
Again, individual dimensions of precarity have been studied – such as the effects of housing insecurity on biological ageing (Clair et al. 2023) or of care-giving on physical and mental health (Brimblecombe and Cartagena Farias 2022) – but the effect of overall precarity has not been examined.In this study, we therefore develop a measure of later life precarity and examine its association with frailty in older adults.；Grenier (2020) has explicitly linked frailty and precarity, arguing that precarity offers a framework through which we can better understand the frail state as one that arises in a social and political context marked by features such as the marketisation of formal care services, rather than it being purely a biomedical product.；Here, we build on this argument by explicitly modelling the association between frailty and the social risks faced by older adults in such precarious social and political contexts.
核心结论
There is also a substantial literature demonstrating the inequalities in frailty prevalence by socio-economic status (e.g.；Notably, they demonstrate that the level of income precarity is determined not only by employment-related factors but also by factors such as martial status, care-giving responsibilities and housing tenure.；Full model results are provided in Supplementary Table 6.DiscussionSeveral key findings emerge from these results.
局限
However, precarity has also been used to understand growing exposure to risk in other social domains.；As such, precarity does not just represent insecurity faced by older adults in a single domain; rather, it represents a generalised exposure to risk across multiple domains that results in ‘life worlds that are inflected with uncertainty and instability’ (Waite 2009, p. 416) and which arise out of policy contexts shaped by a retrenchment of the welfare state, rearrangement of labour market conditions and a decline in state-provided services (Phillipson 2020).However, in existing research, few studies have attempted to quantitatively capture precarity as it pertains to older adults.；However, unweighted estimates may not be representative of the population, especially due to bias introduced through sample attrition across waves.
