Harvard Gazette (“Coffee drinking tied to lower risk of suicide“):
Drinking several cups of coffee daily appears to reduce the risk of suicide in men and women by about 50 percent, according to a new study by researchers at the Harvard School of Public Health (HSPH). The study was published online July 2 in The World Journal of Biological Psychiatry.
“Unlike previous investigations, we were able to assess association of consumption of caffeinated and non-caffeinated beverages, and we identify caffeine as the most likely candidate of any putative protective effect of coffee,” said lead researcher Michel Lucas, research fellow in the Department of Nutrition at HSPH.
The authors reviewed data from three large U.S. studies and found that the risk of suicide for adults who drank two to four cups of caffeinated coffee per day was about half that of those who drank decaffeinated coffee or very little or no coffee.
Caffeine not only stimulates the central nervous system but may act as a mild antidepressant by boosting production of certain neurotransmitters in the brain, including serotonin, dopamine, and noradrenaline. This could explain the lower risk of depression among coffee drinkers that had been found in past epidemiological studies, the researchers reported.
In the new study, researchers examined data on 43,599 men enrolled in theHealth Professionals Follow-Up Study (HPFS) (1988-2008), 73,820 women in the Nurses’ Health Study (NHS) (1992-2008), and 91,005 women in the Nurses’ Health Study II (NHSII) (1993-2007). Caffeine, coffee, and decaffeinated coffee intake was assessed every four years by
