A prospective study in the US showed that optimism was associated with lower mortality of numerous causes. The study evaluated the association between optimism and cause-specific mortality in 70021 women using Cox proportional hazard models. Dispositional optimism was measured in 2004; all-cause and cause-specific mortality rates were assessed from 2006 to 2012. A higher degree of optimism was associated with a lower mortality risk. After adjustment for sociodemographic confounders, compared with women in the lowest quartile of optimism, women in the highest quartile had a hazard ratio of 0.71 for all-cause mortality. Adding health behaviors, health conditions, and depression attenuated but did not eliminate the associations (hazard ratio = 0.91). Associations were found for various causes of death, including cancer, heart disease, stroke, respiratory disease, and infection. It has been demonstrated in randomized trials that optimism can be learned.
