What is high blood pressure?

• A blood pressure reading above 130/80 mmHg is considered high. High blood pressure is commonly an asymptomatic condition, often known as “ the silent killer”.

• Blood pressure measurements indicate how strongly blood presses against arterial walls as it is pumped around the body by the heart.

• Blood pressure is measured in millimetres of mercury (mmHg) and is recorded in two readings, systolic over diastolic.

Systolic refers to the pressure of the blood when the heart beats to pump it out.

Diastolic refers to the pressure of the blood when the heart rests in between beats.

Key facts on high blood pressure

• Affects one in three adults worldwide

• Affects men more than women

• Affects poorer populations more than others

• Is implicated in 13% of deaths worldwide

• Is identified in WHO’s Health 2020 policy as one of the WHO European Region’s major contributors to disease

Why high blood pressure is apublic health concern

• High blood pressure strains the arteries and heart raising the probability of heart attack, stroke and kidney disease.

• High blood pressure can lead to hypertension.

• Hypertension is diagnosed if readings on separate occasions consistently show blood pressure to be 140/90 mmHg or higher.

• Hypertension is identified as the world’s most prevalent preventable disease in WHO’s Health 2020 policy.

Risk factors for high blood pressure

• A diet high in saturated fat• Excessive salt consumption• Overweight and obesity• A sedentary lifestyle and lack of exercise• Excessive alcohol consumption• Smoking• Un-managed stress• A family history of high blood pressure• Being over 65 years of age• Co-morbidities such as diabetes

Manage high blood pressure by:

• eating a healthy diet• reducing salt intake• exercising regularly• stopping smoking• reducing alcohol consumption• managing stress• having regular blood pressure checks

The WHO responseThe WHO Health 2020 policy identifies high blood pressure as a major contributor to disease, and hypertension as the world’s most prevalent preventable disease.

High blood pressure is the theme of World Health Day 2013, with a particular emphasis on reducing dietary salt intake.

WHO’s current European policy

Priority intervent ions of the act ion plan for noncommunicable diseases 2012-2016 include:

• promotion of a healthy diet through marketing and fiscal measures

• elimination of trans fats• salt reduction• cardio-metabolic risk reduction assessment and

management• promotion of physical activity and mobility

Key intervent ions• Encourage regular blood pressure checks• Encourage patients to be aware of their individual risks• Establish effective tools for early identification,

management and control• Promote physical activity, dietary improvement and salt

reduction• Provide low-cost antihypertensive medication• Set target for mean blood pressure reduction levels
