BioMed Central is an STM (Science, Technology and Medicine) publisher which has pioneered the open access publishing model. BMC Medicine is the flagship medical journal of the BMC series, publishing original research, commentaries and reviews that are either of significant interest to all areas of medicine and clinical practice, or provide key translational or clinical advances in a specific field.ģ.

Regional alcohol consumption and alcohol-related mortality in Great Britain: novel insights using retail sales data So we should probably consider people’s blood type as a potential non-modifiable contributor to the risk, and doctors may, in some cases, choose to consider a more vigorous approach to targeting modifiable risk factors among people with non-O blood types.” Doctors assess the risk of cardiovascular disease and death based on several ‘risk factors’ some of these factors such as smoking and obesity are modifiable, and some like age and sex are not. Lead author, Arash Etemadi from the US National Cancer Institute, says: “These results may have implications for risk screening in individuals with certain blood groups. They believe that although some of the increase in mortality could be due to these differences in cholesterol levels, the effect of blood group antigens on blood coagulation and thrombus formation is another important mechanism, but further studies are needed to verify this. The researchers also found that cholesterol levels are higher among certain blood groups. There was no significant association between blood groups and dying from cancer, but an increased risk of developing gastric cancer was seen among those having the A and B blood groups.Īlthough many health impacts of blood groups, such as cardiovascular disease and cancer, have been studied before, this is the first study to look at blood groups and longevity in the general population.
The results of the study showed that during this follow-up, people with non-O blood group (A, B and AB), had, on average, 9% higher risk of death from a medical disease, and 15% higher risk of dying from cardiovascular disease. The most common causes of death were cardiovascular disease (1879 participants, 51.9% of total deaths) and cancer (775 people, 21.4% of total deaths). During an average period of 7 years, 3623 of the cohort participants died.
This cohort was followed-up on a yearly basis with a follow-up rate of 99%. All participants were initially interviewed and their blood type determined. Researchers from the US National Cancer Institute and Tehran University of Medical Sciences studied a cohort of 50,045 people over the age of 40 in Iran since 2004.
The main blood group system, in humans, consists of four types: A, B, AB and O. The differences in the blood groups are brought about by variations in the antigens – molecules– found on the surface of all human cells, including red blood cells. These results could be used alongside of other measures for weighing up risk of death from certain diseases.ĭetermination of the blood group is based on genetic inheritance from our parents. Having a non-O blood group is associated with an increased risk of death, particularly from cardiovascular disease (such as ischemic heart disease and stroke), according to research published in open access journal BMC Medicine.
