Relationship between depression and pancreatic cancer in the general population

Psychosom Med. Sep-Oct 2003;65(5):884-8. doi: 10.1097/01.psy.0000088588.23348.d5.

Abstract

Objective: Prior research suggesting a relationship between pancreatic cancer and depression conducted on clinical populations has been subject to recall bias. We reexamined this association using longitudinal population-based data.

Methods: This was a retrospective cohort study using longitudinal insurance claims data.

Results: Men with mental disorders were more likely to develop pancreatic cancer than those without psychiatric claims (odds ratio 2.4, confidence interval 1.15-4.78). Depression more commonly preceded pancreatic cancer than it did other gastrointestinal malignancies (odds ratio 4.6, confidence interval 1.07-19.4) or all other cancers (odds ratio 4.1, confidence interval 1.05-16.0).

Conclusions: Depression and pancreatic cancer are associated in the general population.
