More than one hundred thousand people took part in the study. For one week, the subjects had to wear accelerometers all the time - devices that work as sensors for changing the position of an object in space. So scientists tracked the motor activity of the participants, writes gazeta.ru.
Six years after the end of the experiment, 414 people developed dementia. After adjusting for demographic data (age, gender, level of education, genetics) and lifestyle features (physical activity, diet, bad habits), it turned out that a sedentary lifestyle increases the risk of developing dementia.
Scientists have noted that the likelihood of this disease is rapidly increasing if a person spends 10 hours a day or more in a sitting position. In addition, breaks for physical activity did not reduce the risk of dementia if the total sitting time was 10 hours.
To determine the level of physical activity that can offset the negative effects of a sedentary lifestyle, additional research is needed.
