Objective: To investigate the detection rate of uterine fibroids in non-menopausal women and its association with metabolic parameters, providing clinical evidence for early risk identification and intervention for this disease. Methods: This cross-sectional study included 8 893 non-menopausal women aged 20-50 years who underwent gynecological ultrasound examinations at the Department of Health Management, the Second Affiliated Hospital of Xi'an Jiaotong University, between January 2025 and August 2025. Based on ultrasound findings, participants were divided into the uterine fibroid group(n=1 278) and the non-uterine fibroid group(n=7 615). Additionally, participants were stratified by age into a young group(≤44 years, n=7 381) and a middle-aged group(45-50 years, n=1 512). General characteristics and metabolic parameters were collected for all participants. Univariate analysis was used to compare differences in metabolic indicators between groups, and Logistic regression models were applied to assess the association between metabolic parameters and uterine fibroids. Results: The overall detection rate of uterine fibroids was 14.4%, with rates of 11.4% in the young group and 29.0% in the middle-aged group. Compared with the non-uterine fibroid group, the uterine fibroid group had significantly higher levels of age, body mass index, waist circumference, systolic blood pressure, diastolic blood pressure, fasting blood glucose, total cholesterol, triglycerides, and low-density lipoprotein cholesterol, as well as higher prevalence rates of hypertension, hyperglycemia, and dyslipidemia(all P<0.05). Multivariate Logistic regression analysis showed that in the young group, hypertension(OR=3.807,95%CI:2.774-5.224), hyperglycemia(OR=2.284,95%CI:1.531-3.408), and dyslipidemia(OR=1.645,95%CI:1.337-2.022) were independent risk factors for uterine fibroids(all P<0.001). In the middle-aged group, only hypertension(OR=1.539,95%CI:1.078-2.198) and hyperglycemia(OR=2.026,95%CI:1.406-2.919) were independent risk factors(both P<0.05). Nested Logistic regression further indicated that metabolic syndrome as a whole was not independently associated with uterine fibroids(P>0.05), and its apparent effect was primarily attributable to the independent contributions of individual metabolic components. Conclusion: The detection rate of uterine fibroids in non-menopausal women exhibits significant age-related differences, and the risk factors vary by age group. Young women should prioritize the monitoring and management of blood pressure, blood glucose and lipid levels, whereas middle-aged women should focus on the control of blood pressure and blood glucose. These findings have important implications for early risk identification and intervention of uterine fibroids. |
