Risk factors for self-reported uterine fibroids: A case-control study

Abstract

To identify risk factors for uterine fibroids, a case-control design was used to analyze data from control subjects enrolled in the Cancer and Steroid Hormone Study. Case patients were 201 women who reported a history of uterine fibroids, and control subjects were 1503 women without fibroids, individually matched by age to case patients. Reporting of fibroids was more frequent among premenopausal women, women who had frequent Papanicolaou (Pap) smears, women who used oral contraceptives and had infrequent Pap smears, and women with higher education. Reporting of fibroids was less frequent among women with a lower body mass index who were current or long-time smokers.
