Caffeine and depression – is there a connection?

A new study published in the Archives of Internal Medicine, based on data from more than 50,000 participants in the Nurses’ Health Study, suggests that daily consumption of 2-3 cups of caffeinated coffee may be tied to a lower risk of depression in women.

The study’s authors cautioned that their results needed further exploration before leaping to make any recommendations based on the findings of a possible protective effect of caffeine, mainly from coffee consumption, on the risk of depression.

Michelle Riba, M.D., M.S., and John Greden, M.D., professors in the U-M Department of Psychiatry and associate and executive directors of the U-M Depression Center, respectively, were quoted in articles in WebMD and Bloomberg News (Riba) and the Huffington Post (Greden) that reviewed the study’s implications.
