Can You Reduce Stroke Risks following a Healthy Lifestyle?

Guwahati: Maintaining a healthy lifestyle has always been the key to longevity. People can reduce the risk of getting affected by serious diseases by maintaining a healthy lifestyle. As per a recent study, life-threatening diseases like a stroke can now be avoided by following a normal and healthy lifestyle. People at high genetic risk of stroke can still reduce their chance of having a stroke by sticking to a healthy lifestyle, in particular stopping smoking and not being overweight, finds a study in The British Medical Journal.

The study suggests that people at high genetic risk of stroke can still reduce their chances of having a stroke by sticking to a healthy lifestyle by stopping smoking habits and not being overweight, etc. The study which appeared in the BMJ highlights, the potential of lifestyle measures to reduce the risk of stroke across entire populations, even in those at high genetic risk of stroke.

Stroke is a complex disease caused by both genetic and environmental factors, including diet and lifestyle.

As per reports, a team of international researchers decided to find out by investigating whether a genetic risk score for stroke is associated with an actual stroke in a large population of British adults.

They developed a genetic risk score, based on 90 gene variants known to be associated with stroke from 306,473 white men and women in the UK Biobank – a database of biological information from half a million British adults.

Participants were aged between 40 and 73 years and had no history of stroke or heart attack. Adherence to a healthy lifestyle was based on four factors: non-smoker, a diet rich in fruit, vegetables, and fish, not overweight or obese (body mass index less than 30), and regular physical exercise.

Hospital and death records were then used to identify stroke events over an average follow-up of 7 years.

Across all categories of genetic risk and lifestyle, the risk of stroke was higher in men than women.

Risk of stroke was 35% higher among those at high genetic risk compared with those at low genetic risk, irrespective of lifestyle.

However, an unfavourable lifestyle was associated with a 66% increased risk of stroke compared with a favourable lifestyle, and this increased risk was present within any genetic risk category.

The study also revealed that high genetic risk combined with an unfavourable lifestyle profile was associated with a more than twofold increased risk of stroke compared with a low genetic risk and a favourable lifestyle. These findings highlight the benefit for the entire population of adhering to a healthy lifestyle, independent of genetic risk.

The researchers concluded that their findings “highlight the potential of lifestyle interventions to reduce the risk of stroke across entire populations, even in those at high genetic risk of stroke.”
