Which of the following is a risk factor for developing uterine fibroids?

Increasing age is indeed a significant risk factor for developing uterine fibroids. As women age, particularly during their reproductive years leading up to menopause, the hormone levels, especially estrogen, can influence the development of fibroids. Fibroids are more commonly diagnosed in women between the ages of 30 and 40, and their prevalence tends to decline after menopause when estrogen levels decrease. This hormonal link highlights why age is a key risk factor in the growth and formation of uterine fibroids.

Other factors such as body weight, diet, or exercise typically do not have a direct correlation with the likelihood of developing fibroids, particularly when compared to the impact of increasing age.
