Socioeconomic differences in physical disability at older age

Area of Science:

• Gerontology
• Public Health
• Sociology

Background:

• Investigates the link between socioeconomic position (SEP) and physical disability in older adults.
• Utilizes a comprehensive framework including education, social class, and wealth.
• Employs data from the English Longitudinal Study of Ageing (ELSA).

Purpose of the Study:

• To examine the association between SEP and physical disability in later life.
• To understand the roles of education, social class, and wealth in this relationship.
• To explore potential temporal relationships between SEP indicators and disability.

Main Methods:

• Combines self-reported difficulties in daily living and motor skills into disability categories (none, mild, severe).
• Uses wealth, education, and social class as indicators of SEP.
• Applies multinomial regression to analyze SEP and physical functioning associations.

Main Results:

• Higher SEP (wealth, education, social class) correlates with lower physical disability rates.
• The association is stronger in younger age groups and among men.
• Education's direct impact on disability diminishes when accounting for occupation and wealth, suggesting a temporal pathway.

Conclusions:

• Socioeconomic factors significantly influence physical disability prevalence and severity in older age.
• Wealth emerges as a more critical SEP factor for physical disability than social class or education.
• Socioeconomic gradients in physical disability are steeper for men and younger older adults.
