Researchers from Kunming Medical College in China conducted a collaborative study to explore whether extended sitting influences the likelihood of developing uterine fibroids. The findings were reported in a peer‑reviewed medical journal, highlighting a potential link between prolonged sedentary behavior and gynecological health risks.
Uterine myomas, the most common benign tumors in women of reproductive age, may not show symptoms in many cases. When symptoms appear, they often include abnormal menstrual bleeding and abdominal discomfort. The appearance and growth of myomas are influenced by a mix of genetic factors, yet lifestyle choices can also play a role. The research team sought to determine how long-term sitting might affect fibroid risk, recognizing that everyday sedentary patterns could contribute to metabolic changes associated with tumor development.
The study enrolled 6,623 women aged 30 to 55. Participants provided information on childbirth history, age at first birth, contraception use, diet, physical activity, height, and weight. They also reported their typical daily time spent sitting while engaging in sedentary activities such as board games, reading, knitting, and similar pastimes. Based on sitting duration, participants were sorted into four groups: under two hours per day, two to just under four hours, four to six hours, and six hours or more per day.
Results indicated a positive relationship between sitting time and fibroid risk. Women who spent six hours or more sitting daily exhibited roughly double the risk of developing uterine fibroids compared with those who sat less than two hours per day.
One plausible explanation is that extended sedentary time tends to be linked with weight gain and obesity, both of which have been associated with an increased risk of fibroids. Additional research is needed to clarify the biological mechanisms at work and to determine whether reducing sitting time could lower fibroid risk, independent of other lifestyle factors.
Earlier discussions in the medical community have emphasized pelvic floor health for women, underscoring the broader importance of physical activity for gynecologic well‑being. While the current findings add to the growing evidence base, they also highlight the need for comprehensive strategies that integrate movement, body weight management, and regular health screening for women in the 30‑plus age range.
