Objectives: The aim of this study was to assess which social status factors predispose a person to dying with activity of daily living (ADL) disability in later life.
Methods: We followed 243 deceased members of the Swiss Interdisciplinary Longitudinal Study on the Oldest Old annually up to 8 years before their deaths. Using a multilevel regression, we analyzed age at death, gender, occupational category, and geographic area as potential factors predisposing a person to ending life with ADL disability.
Results: Disability scores showed a substantial increase as death approached. Individuals from a lower occupational category were at higher risk of ADL disability and experienced a greater functional decline prior to death compared to those from higher occupational categories.
Discussion: Consistent with the cumulative disadvantage theoretical framework, the health differential between the occupational categories seems to be exacerbated prior to death.
