Background A major problem that affects women of reproductive age globally is sterility. new statistic called Relative Fat Mass (RFM) provides an accurate representation the percentage total body fat in people. This study aims to investigate relationship between RFM and sterility fertility-age American women. Methods employed a cross-sectional design using data collected from NHANES 2013 2018. The association was investigated logistic regression analysis, controlling for number variables. results were more resilient when transformed into four-category variable order further examine patterns different levels dose-response illustrated restricted cubic spline (RCS) analysis. Sensitivity subgroup analyses also conducted assess robustness consistency results. Results included 3,197 aged 18–45, consisting 2,854 non-sterile participants 343 sterile participants. First, fully adjusted model, prevalence had positive correlation (OR = 1.05, 95% CI 1.01–1.09). When converting continuous categorical variable, significantly greater highest quartile than lowest 2.59, 1.40–4.82). Furthermore, found be positively linearly correlated by RCS with rates sharply increasing as rose. frequency shown constant throughout various populations, according analysis across stratified parameters. Finally, sensitivity confirmed reliability study’s findings. Conclusion representative sample showed may help identify at risk sterility, waist circumference management could potentially lower

The use of visceral obesity as an indicator for predicting female infertility risk has not been well established. body roundness index (BRI) is a novel, non-invasive fat; however, previous reports have addressed the relationship between BRI and infertility. This study sought to fill this research gap by investigating association
