| description | Objectives We aimed to explore the epidemiological characteristics of suspected adenomyosis within a physical examination population in China.Design A retrospective, nested case-control study; we matched healthy people and those with potential adenomyosis on a 1:2 ratio by age.Setting A tertiary hospital health management centre.Participants We included 15–60 years old women who underwent at least one uterine examination from October 2017 to December 2020, excluding those who had undergone hysterectomy and menopause.Primary and secondary outcome measures We estimated the incidence and prevalence rate of suspected adenomyosis. Conditional logistic regression was used to estimate associations between serum biomarkers and potential adenomyosis. Areas under the receiver-operating characteristic curves (AUC) were used to determine the cut-off point of the cancer antigen 125 (CA125) level for suspected adenomyosis.Results A total of 30 629 women had uterus-related imaging examinations; 877 had suspected adenomyosis. The standardised incidence and prevalence of suspected adenomyosis was 1.32% and 2.35%, respectively, for all age groups. The conditional logistic regression analysis results showed that total bilirubin≥18.81 µmol/L (HR: 2.129; 95% CI 1.067 to 4.249; p<0.0321) and CA125 levels (HR: 1.014; 95% CI 1.002 to 4.731; p<0.0273) were positively correlated with onset of suspected adenomyosis; body mass index>24 kg/m2 (HR: 1.262; 95% CI 1.055 to 1.511; p<0.0109), CA125 levels (HR: 1.007; 95% CI 1.006 to 1.009; p<0.0001), and blood platelet levels (HR: 1.002; 95% CI 1 to 1.003; p<0.0141) were positively correlated with potential adenomyosis. The optimal cut-off of CA125 for new suspected adenomyosis was 10.714 U/mL, with a sensitivity of 77.42%, specificity of 53.76%, and AUC of 0.7841 (95% CI 0.7276 to 0.8407).Conclusions The disease burden of suspected adenomyosis remains huge and can be informed by biomarkers. The disease-specific threshold of CA125 will support further preventive strategy development in population.Trial registration number ChiCTR2100049520, 2021/8/2. |
