Key result
Low cumulative socioeconomic status was associated with a 44% increased risk of all-cause mortality (HR 1.44) compared to high socioeconomic status in older Australian men.
Why the study?
Conflicting evidence exists regarding the association of socioeconomic status with mortality in older people, and little is known about the underlying mechanisms or mediating health-related behaviours.
Does low socioeconomic status increase mortality in older men?

Comparison
Lowest tertile vs highest tertile of cumulative SES score
Design
Prospective population-based cohort study
Follow-up

Association warrants consideration in prognostic models for older men; leaves open whether SES-targeted strategies improve survival.
Cohort (n=1,527)
Does low socioeconomic status increase mortality in older men?
Hazard Ratio: 1.44 (95% CI 1.21–1.7)
Absolute Event Rate: 64.8% vs 50.3%
Low socioeconomic status is associated with increased all-cause and cause-specific mortality in older men, with health-related behaviors accounting for less than a quarter of this association.
Khalatbari‐Soltani et al. (2020) conducted a cohort in Older adults (general population) (n=1,527). Low socioeconomic status (lowest tertile of cumulative SES score) vs. High socioeconomic status (highest tertile of cumulative SES score) was evaluated on All-cause mortality (HR 1.44, 95% CI 1.21 to 1.70). Low cumulative socioeconomic status was associated with a 44% increased risk of all-cause mortality (HR 1.44) compared to high socioeconomic status in older Australian men.
