Relation between vitamin D and uterine fibroid

Background; Uterine fibroids (UFs) are benign tumors that develop from the uterus' smooth muscle cells and are mostly found in the pelvic. Aim of the work; we aimed to compare serum vitamin D level between patients, have uterine fibroids and those without. Subjects and methods; our current study included 90 females and was conducted as a case control study; 50 were diagnosed with uterine fibroid and 40 were healthy volunteers (control) during the period from July 2019 to July 2020.  they were recruited from Al Zahra’a University Hospital. Serum vitamin D level was measured by ELISA. Results; Vitamin D serum concentrations were significantly lower in the studied females with UFs compared to healthy controls (mean 19.24 ±16.0 vs. 33.83 ±17.5) ng/mL in cases and controls, respectively, with a statistically significant p-value <0.001. Serum vitamin D levels have a significant, linear, negative, moderate association with uterine fibroids size. Conclusion; in our study group, reduced serum vitamin D levels were found to be inversely related to UF burden. A lack of vitamin D may be a risk factor for the incidence of uterine fibroids
