Studies have suggested the potential roles of serum macronutrients such as calcium and magnesium in the development of uterine fibroids. The primary objective was to assess the association between serum magnesium and calcium levels and the prevalence of uterine fibroids in women of reproductive age. A cross-sectional study of 194 parity-matched women with or without a sonographic diagnosis of uterine fibroids enrolled at a university teaching hospital in Lagos, Southwest Nigeria. Participants' sociodemographic, ultrasound, and anthropometric information as well as the estimated serum levels of calcium and magnesium were collected for statistical analyses. This study found significant negative associations between low serum calcium levels and uterine fibroids (adjusted odds ratio = 0.06), uterine size, and the number of fibroid nodules. However, no significant association was observed between serum magnesium levels and uterine fibroids. This study found significant inverse associations between low serum calcium levels and uterine fibroids, uterine size, and the number of fibroid nodules.
