In a new study published in the journal eClinicalMedicine, researchers have explored in detail how different smoking habits affect the risk of having a stroke.
It found that current smokers have a higher risk of having a stroke than never smokers, with the association being stronger with ischemic stroke, which is the most common type and occurs when blood clots reach the brain. Fails to reach. The international study involved researchers from St. John’s Medical College and Research Institute, Bangalore.
Both filtered and non-filtered cigarettes were linked with an increased risk of stroke, and passive smoking – exposure to environmental tobacco smoke (ETS) – for more than ten hours a week nearly doubled the risk of stroke. found, especially ischemic and intracerebral hemorrhage. (ICH). ICH is caused by bleeding from a burst blood vessel in the brain.
The team also found that in young heavy smokers under the age of 50 (more than 20 cigarettes a day), the risk of stroke more than doubled, compared to 1.5 times in participants aged 70 and older. was more than increasing.
In people aged 50-59, the risk of large vessel stroke involving large vessels supplying blood to the brain increased 8 times.
At a regional level, the researchers found that the risk of stroke was highest among current smokers in Western European and North American regions. Data from participants from 32 high-, middle- and low-income countries were analyzed, including people from Africa, South Asia (India and Pakistan) and South America. They were recruited between January 2008 and August 2015.
The researchers found that across different income levels, the risk of stroke from smoking was higher in high-income countries (HICs) than in low- and middle-income countries (LMICs), with younger smokers at greater risk than older ones. It happens. The number of cigarettes smoked per day increased the risk of stroke, especially in HICs, they said.
The researchers said the study’s findings are relevant to global efforts to reduce tobacco use and exposure.
Their suggested measures include preventing youth from starting to smoke and encouraging existing smokers to quit, as well as legislation aimed at creating and supporting smoke-free environments.
Nearly 46 percent of young men in Southeast Asia were found to be current smokers, compared to more than 16 percent of young women in Eastern/Central Europe/Middle East.
