Abstract
PurposePrevious research has shown a significant association between psychological distress (PD) and all-cause mortality. However, this association is not fully explored, and life expectancy by PD is unknown. MethodsWe used the pooled 1997–2014 data from the National Health Interview Survey linked to National Death Index (n = 513,081) to examine the association of the Kessler 6-item PD scale with life expectancy and all-cause mortality. Life expectancy by PD was computed using the standard life table method. Cox regression was used to model survival time as a function of PD and sociodemographic, behavioral, and health characteristics. ResultsThe age-adjusted mortality rate for adults with serious PD (SPD) was 2632 deaths per 100,000 person-years, compared with 1428 for those without PD. Life expectancy was inversely related to PD. At age 18, those with SPD had a life expectancy of 45.0 years, compared with 55.6 years for those without PD. The age-adjusted relative risk of all-cause mortality was 125% higher for adults with SPD (hazard ratio = 2.25; 95% confidence interval = 2.14, 2.37) than those without PD. Mortality risk associated with SPD remained (hazard ratio = 1.14; 95% confidence interval = 1.08, 1.20) after covariate adjustment. ConclusionsU.S. adults with SPD had significantly higher mortality risk and lower life expectancy.
