Relative Risk: 1.53 (95% CI 1.05–2.24)

Depressive symptoms were associated with higher all-cause mortality in elderly adults, especially when combined with smoking; leaves open whether targeted interventions improve survival.
Fortes et al. (2011) conducted a cohort in Depressive symptoms (n=167). Depressive symptoms (GDS-15 > 7) vs. Non-depressed subjects was evaluated on All-cause mortality (RR 1.53, 95% CI 1.05-2.24). Depressive symptoms in elderly people were associated with an increased risk of all-cause mortality (RR 1.53; 95% CI 1.05-2.24), which was further elevated when combined with smoking (RR 2.61).
