BLOOD DONATION

Each additional annual blood donation was associated with a 7.5% lower risk of death

Studies have repeatedly demonstrated that blood donors experience lower mortality than the general population, but some have suggested that this may be due to healthier people donating blood.

A 2015 analysis of the Scandinavian Donation and Transfusion database (SCANDAT) found that after adjusting for the internal healthy donor effect, each additional annual donation of blood was associated with a 7.5% decreased risk of death over some number of years.

(I’m waiting for a copy of the study to find out the average number of years of follow-up.)

In other words, the more frequent someone donated blood, the lower their risk of death.

The analyses included 1,182,495 donors of whom 15,401 died during 9,526,627 person-years of follow-up.

BLOOD DONATION

Men who donated blood were 88% less likely to have a heart attack over 9 years

Men who donated blood were 88% less likely to have a heart attack during a 9-year followup compared to men who did not donate blood according to a 1998 study from Finland.

This was after adjusting for age and coronary disease risk factors.

Only one (1) man out of 153 (0.7%) who had donated blood in the previous 24 months before baseline had a heart attack during 1984 to 1995, whereas 316 men of 2529 (12.5%) who had not donated blood had a heart attack.

“These findings suggest that frequent blood loss through voluntary blood donations may be associated with a reduced risk of acute myocardial infarction in middle-aged men,” the authors of the study concluded.
