Systematic review finds better quality of life associated with lower mortality risk in the general population, suggesting value as a screening tool.

The study aims to synthesize evidence on the relationship between quality of life and mortality in the general population.
Conducted an electronic search of MEDLINE, EMBASE, and PsycINFO databases.
Included studies assessed quality of life using standardized tools and analyzed mortality risk.
Performed meta-analyses using a random-effects model on identified studies.
Out of 4184 articles, 47 were included, involving around 1,200,000 participants.
43 studies (91.5%) showed that better quality of life correlates with lower mortality risk.
Higher health-related quality of life had a hazard ratio of 0.633 (95% CI: 0.514 to 0.780) for lower mortality risk.

Phyo et al. (2020) studied this question.
