Pockets of high-rate counties also were found in Florida, New Mexico, Arizona, Nevada, and Missouri. The map shows that concentrations of counties with the highest hypertension prevalence – meaning the top quintile – are located primarily in Mississippi, Louisiana, Arkansas, Oklahoma, Texas, Kentucky, Tennessee, Alabama, Georgia, South Carolina, North Carolina, Virginia, Maine, and Michigan. However, this map likely underreports the true effect of hypertension in each state, because about 1 in 5 adults with high blood pressure is unaware of it and would not report having it. Below is a map showing the self-reported rate of hypertension by county. High blood pressure is more common in some areas of the United States than in others. Rates of High Blood Pressure Vary by Geography Among those recommended to take blood pressure medication, blood pressure control is higher among non-Hispanic white adults (32%) than in non-Hispanic black adults (25%), non-Hispanic Asian adults (19%), or Hispanic adults (25%).High blood pressure is more common in non-Hispanic black adults (56%) than in non-Hispanic white adults (48%), non-Hispanic Asian adults (46%), or Hispanic adults (39%).A greater percentage of men (50%) have high blood pressure than women (44%).Uncontrolled high blood pressure is common however, certain groups of people are more likely to have control over their high blood pressure than others. Rates of High Blood Pressure Control Vary by Sex and Race High blood pressure costs the United States about $131 billion each year, averaged over 12 years from 2003 to 2014.Almost two out of three of this group (19 million) have a blood pressure of 140/90 mmHg or higher. About 34 million adults who are recommended to take medication may need it to be prescribed and to start taking it.About half of adults (45%) with uncontrolled hypertension have a blood pressure of 140/90 mmHg or higher.About 1 in 4 adults with hypertension have their hypertension under control (22.5%, 27.0 million).Nearly half of adults have hypertension (48.1%, 119.9 million), defined as a systolic blood pressure greater than 130 mmHg or a diastolic blood pressure greater than 80 mmHg or are taking medication for hypertension.In 2021, hypertension was a primary or contributing cause of 691,095 deaths in the United States.Having hypertension puts you at risk for heart disease and stroke, which are leading causes of death in the United States.This was only 1.82% of the residential population.Ģ4% were 1st time donors 40% were regular donors and 17% were youth (25 years of age and below) donors. HSA keeps 9 days stockpile of blood supply to ensure sufficient blood supply during times of emergency. That is 325 units every day or 118,750 units in the year. In 2023, 14 units of blood are required every hour in Singapore. White blood cells: helps the body fight infections.Red blood cells: helps carry oxygen and carbon dioxide to organs and tissue.Plasma: the liquid portion of blood, containing mostly water, electrolytes, nutrients, and proteins such as antibodies and clotting factors. It is a way to help patients in need and make our society a better place. Through altruistic blood donation, we also celebrate the value of being kind and generous to others. This could put both the donor and the person receiving the blood at risk. If donors were paid or given incentives, they might be tempted to withhold important information. Singapore’s VNRBD policy is in place to make sure that donors are honest about their medical history and any high-risk social activities they may have engaged in. This is aligned with the World Health Organisation and the International Federation of Red Cross and Red Crescent Societies. This is known as voluntary non-remunerated blood donation (VNRBD) and is the foundation of a safe and sustainable blood supply. In Singapore, blood donors donate blood or blood components such as platelets and plasma on their own free will and they do not receive any incentives for doing so.

Whole blood donations collect the blood with all its components, while apheresis donations collect specific blood components such as plasma or platelets. The fluid (plasma) portion of your donated blood will be replaced in a few days. About 8% to 12% of your blood volume (depending on your weight) will be taken during blood donation. During a donation, only 350 to 450 ml of blood is drawn. The average adult has 4 to 5 litres of blood.
