The most common blood type among the population in the United States is O-positive. Around 53 percent of the Latino-American population in the U.S. has blood type O-positive, while only around 37 percent of the Caucasian population has this blood type. The second most common blood type in the United States is A-positive. Around 33 percent of the Caucasian population in the United States has A-positive blood type. Blood type O-negative Those with blood type O-negative are universal donors as this type of blood can be used in transfusions for any blood type. O-negative blood type is most common in the U.S. among Caucasian adults. Around eight percent of the Caucasian population has type O-negative blood, while only around one percent of the Asian population has this blood type. Only around seven percent of all adults in the United States have O-negative blood type. Blood Donations The American Red Cross estimates that someone in the United States needs blood every two seconds. However, only around three percent of age-eligible people donate blood yearly. The percentage of adults who donated blood in the United States has not fluctuated much for the past two decades. In 2021, around 15 percent of U.S. adults donated blood, the same share reported in the year 2003.

The eight main blood types are A+, A-, B+, B-, O+, O-, AB+, and AB-. The most common blood type in the United States is O-positive, with around 38 percent of the population having this type of blood. However, blood type O-positive is more common in Latino-Americans than other ethnicities, with around 53 percent of Latino-Americans with this blood type, compared to 47 percent of African Americans and 37 percent of Caucasians. Blood donation The American Red Cross estimates that every two seconds someone in the United States needs blood or platelets, highlighting the importance of blood donation. It was estimated that in 2021, around 6.5 million people in the U.S. donated blood, with around 1.7 million of these people donating for the first time. Those with blood type O-negative are universal blood donors, meaning their blood can be transfused for any blood type. Therefore, this blood type is the most requested by hospitals. However, only about seven percent of the U.S. population has this blood type. Blood transfusion Blood transfusion is a routine procedure that involves adding donated blood to a patient’s body. There are many reasons why a patient may need a blood transfusion, including surgery, cancer treatment, severe injury, or chronic illness. In 2021, there were around 10.76 million blood transfusions in the United States. Most blood transfusions in the United States occur in an inpatient medicine setting, while critical care accounts for the second highest number of transfusions.

This statistic illustrates the distribution of blood groups in the French population, according to the Rhesus system. It shows that less than 1 percent of French people had the blood group AB negative.

In 2023, almost 219 thousand people were confirmed to have hemophilia worldwide. At that time, a further 101 thousand people were living with von Willebrand disease. Both of these bleeding disorders are genetic diseases that prevent blood from clotting normally. Bleeding disorders There are multiple types of hemophilia and bleeding disorders including hemophilia A, hemophilia B and various platelet disorders. Globally, hemophilia A has the largest number of people living with a bleeding disorder, followed by von Willebrand disease. Life expectancy for hemophilia has dramatically increased since the advent of medicine to help combat the disorder. Modern medical treatments have extended the life expectancy of a hemophilia patient from 30 to 68 years. U.S. market In the U.S. alone there are over 17 thousand patients with hemophilia and 14 thousand with von Willebrand disease. Hemophilia A is more common than hemophilia B. In the U.S. around 13 thousand patients had hemophilia A as of 2023. Comparatively, just under 4.2 thousand patients had hemophilia B at that time. While hemophilia and other bleeding disorders can affect persons of any ethnicity, von Willebrand patients in the U.S. are largely white or Caucasian. In 2023, around 80 percent of von Willebrand patients were white.

Mean values, followed by their standard deviation, of LF [ms2], HF [ms2], LF [nu], HF [nu] and LF/HF ratio indices at rest and during the active orthostatic test, adjusted for sex, age, ethnicity, body fat percentage and casual blood glucose.

a HDL, high density lipoprotein; LDL, low density lipoprotein; hs-CRP, high-sensitivity C-reactive protein; HOMA-IR, homeostasis model of insulin resistance; and HOMA-Beta, homeostasis model of beta-cell function. ANCOVA adjusted for age, sex, ethnicity and energy intake was used to examine the interaction effect between the ABO blood group and diet adherence on levels of cardiometabolic risk factors. The Tukey-Kramer procedure was used to adjust for multiple comparisons between groups within each ANCOVA.b Mean ± SE (all such values).
