Researchers from Kunming Medical College (China), as part of a scientific team, found that sitting for six hours or more increases the risk of developing uterine fibroids. results published In the British Medical Journal (BMJ).
Uterine myomas are the most common type of benign tumor in women of childbearing age. This growth may not cause any symptoms, but in some women it causes abnormal menstrual bleeding and abdominal pain. The appearance of myomas largely depends on genetic factors. However, an unhealthy lifestyle is also a factor in the development of this type of tumor. Scientists tried to find out how long-term sitting affects the risk of fibroids.
6,623 women between the ages of 30 and 55 participated in the study. Scientists collected information about the number of children each participant had, age at first birth, birth control method, eating and exercise habits, height and weight. Subjects were also asked to indicate how much time they spent in front of the screen playing board games, reading books, knitting, and similar sedentary activities. They were then divided into four groups based on the number of hours they spent sitting. Participants in the first group sat for less than two hours per day, in the second group, 2-3.99 hours per day, in the third group, 4-5.99 hours per day, and in the fourth group, they sat for six or more hours per day.
It turns out that the more free time women spend sitting, the higher their risk of developing uterine fibroids. People who sat for six hours a day had twice the risk of developing such tumors than people who sat for less than two hours.
One possible explanation for the observed associations may be that a sedentary lifestyle is associated with obesity, a risk factor for the development of uterine fibroids. Additional research is needed to better understand these mechanisms.
