Despite exam stress, a long stint in education is good for people's blood pressure, according to researchers in the US.
High blood pressure, or hypertension, is linked to heart attacks, strokes and kidney failure. The study, published in the journal BMC Public Health, shows the link is stronger in women than in men.
The British Heart Foundation said the findings supported the link between deprivation and heart disease risk. Higher levels of education have been linked to lower levels of heart disease. The researchers suggest that blood pressure could be the reason why. The study looked at 30 years of data from 3,890 people who were being followed as part of the Framingham Offspring Study.
