Know Your Numbers

Blood pressure is measured using two numbers. The first (systolic) number represents the pressure in your blood vessels when your heart beats. The second (diastolic) number represents the pressure in your vessels when your heart rest between beats. If the measurement reads 120 systolic and 80 diastolic, you would say "120 over 80" or write "120/80 mmHg."

Alabama Statistics

In 2013, better than 40% of Alabamians reported having high blood pressure. Blood pressure is the force of blood against your artery walls as it circulates through your body. Blood pressure normally rises and falls throughout the day, but can cause health problems if it stays high for a long time. Having high blood pressure raises your risk for heart disease and stroke, the first and fourth leading causes of death in Alabama. Primary hypertension is the number 12 cause of death according to 2013 data, with a rate of 12.1 per 100,000 (587 deaths) and the comparable rate for the nation is 9.7 per 100,000. The estimated morbidity percentage for adults ages 20 and older with hypertension is 32.5% according to the National Center for Health Statistics.
