Last night, the latest research published in the stroke journal "Stroke" of the American Heart Association showed that adults under the age of 60 who sit for long periods of time and do little exercise have a higher risk of stroke in the future.
According to statistics from the American Heart Association, American adults spend an average of 10.5 hours a day on electronic media products such as smartphones, computers, and televisions, especially those aged 50-64.
Data show that since 2010, the number of stroke-related deaths among those over 65 years of age has declined. However, among people aged 35-64, the number of deaths increased, from 14.7 per 100,000 people in 2010 to 15.4 in 2016.
Previous studies have confirmed that the longer adults sit for long periods of time, the higher the risk of cardiovascular and cerebrovascular diseases and the higher the risk of death. Nine out of 10 stroke events can be attributed to modifiable risk factors, such as sedentary behavior.
In this latest study by scholars at the University of Calgary in Canada, more than 140,000 participants in the Canadian Community Health Survey (CCHS) in different years were selected. They had no previous stroke, heart disease or cancer.
Participants were divided into four groups ABCD based on their daily leisurely sedentary time, namely: 4 hours, 4-6 hours, 6-8 hours, and 8 hours. According to the amount of physical activity, they are also divided into four groups. The lowest group of exercise is equivalent to walking for 10 minutes or less a day, which is less than half of the amount of exercise recommended in the American Heart Association guidelines (Supplement: The American Heart Association recommends that adults should walk for at least 10 minutes a week. 150 minutes of moderate-intensity exercise, or 75 minutes of vigorous-intensity exercise). The follow-up of the
study ended at the end of 2017, with an average of 9.4 years. After analysis, it was found that:
1. period A total of 2965 stroke events occurred. The average time from the beginning of the investigation to the occurrence of stroke was 5.6 years. Nearly 90% were ischemic strokes, the most common type.
2. The average daily leisurely sedentary time of all participants was 4.08 hours. Among them, people aged 60 and under have an average of 3.9 hours, people aged 60-79 have an average of 4.4 hours, and people aged 80 and above have an average of 4.3 hours.

3. Among people under the age of 60 with low physical activity, compared with those who sit for less than 4 hours a day for leisurely sitting for more than 8 hours a day, , the risk of stroke increases to more than 4 times.
4. Compared with people who sit for less than 4 hours a day and have a high amount of exercise, those who sit for more than 8 hours a day and have the lowest amount of exercise have a nearly 7-fold increased risk of stroke!
htmlAdults aged 160 and under should be aware that being sedentary for long periods of time with little exercise can have serious adverse health effects, including an increased risk of stroke disease.
In addition, it is worth noting that the study did not pay attention to the sedentary time of the participants at work, which means that people who work sedentary jobs (such as office white-collar workers, programmers, etc.) may have a higher risk of disease.
