In a survey of German doctors aged >75 years, group O appeared to be associated with longer life expectancy9. Findings of two studies performed on centenarians were contradictory. Blood type B was observed more frequently in 269 Japanese centenarians (29.4%) than in controls (21.9%)10.
Is O+ blood type rare?
O+ is the most frequently occurring blood type and is found in 37 percent of the population. O- is found in six percent of the population. This blood is the second most frequently occurring blood type. Thirty-four of every 100 people have A+.
What race has more type A blood?
Racial distribution of ABO blood type in our study was similar to what has been previously reported: black have a higher proportion of O and B blood types, and a lower proportion of A and AB blood types, than whites. However, our study identified fewer patients with Rh-blood type than have been previously reported.
