The longer the training, the lower the risk of heart disease
Previous studies have shown that better education reduces the risk of heart disease. But it was not really clear why. Researchers from Great Britain have now succeeded in at least partially elucidating this connection.
Risk of cardiovascular diseases reduced by a third
Previous research has shown that the risk of cardiovascular diseases such as heart attacks or strokes, which are spent in training, is reduced by about a third per 3.6 years. However, it was not exactly clear why this is so. In a new study by British scientists, this connection has now been at least partially explained.
Reduced BMI and systolic blood pressure
The current study showed that the reduced risk can only be explained by the body mass index (BMI), blood pressure and smoking by 40 percent.
To arrive at this result, researchers from Imperial College London, the University of Bristol, the University of Cambridge and the University of Oxford used statistical and genetic analysis.
The analysis also showed that 3.6 years of additional training was associated with a 1 kg / m2 reduction in BMI and a 3 mmHg systolic blood pressure.
The results of the scientists were published in the British Medical Journal (BMJ).
More intensive examination of health issues
"Although we already knew from previous studies that someone who spends more time in training is less at risk of heart disease and stroke, we did not know the reason for this," explained co-author Dr. Dipender Gill from Imperial College London in a communication.
"Surprisingly, our studies showed that only about half of this protective effect is due to healthy weight, lower blood pressure and less smoking," said the scientist.
"We now need to investigate what other reasons education and a lower risk of cardiovascular disease can have."
According to the researcher, it is possible for people to deal more with health issues after a longer training and to go to a doctor if they have health problems.
You can still intervene after finishing school
Alice Carter, co-lead author from the University of Bristol, said previous measures to extend school attendance improved health. In their opinion, such efforts should continue.
"However, an intervention in education is difficult to achieve and requires major social and political changes," said the scientist.
"Our work shows that there are opportunities to intervene after school to reduce the potential risk of heart disease," said Carter.
"Lowering the BMI, blood pressure, or smoking rate in people who left school at an earlier age could reduce the risk of cardiovascular disease."
However, the expert also pointed out that early school leaving does not necessarily mean that a person develops heart diseases. (ad)
