A person's risk of high blood pressure is clearly linked to their social status, researchers have said.

They studied the socio-demographic aspects of high blood pressure using data from all over the world.

High blood pressure, also known as hypertension, is a ‘silent predator' because it rarely carries any signs or symptoms, despite causing damage to blood vessels and the heart. A person can look and feel well even if they have it. The condition is a major cause of heart attack and stroke and two in three Irish people over the age of 45 are affected.

The researchers from the Centre for Public Health in Vienna, Austria, found that a lower level of education, a low income and the type of job performed are all risk factors for high blood pressure. People with a migration background are also at risk.

The researchers noted that these risk factors more often affect women.

They also pointed out that high blood pressure tends to be more difficult to control in people with a low social status and emphasised that there is a direct link between social status and a person's health behaviours.

"A higher income means finding it easier to make lifestyle choices and a higher education means you are more likely to live a healthier lifestyle," they commented.

Differences in social status can also lead to different uptakes of health services. For example, those with a lower social status are less likely to avail of health screening. They are also less likely to have private health insurance which can limit their options.

The researchers also pointed out that health conditions can influence social status.

"A lower social status can be a consequence of poor health. Illness can therefore lead to disadvantages in terms of education and career opportunities," they said.

The researchers released their findings ahead of World Hypertension Day (May 17).
