Overactive bladder (OAB) represents a frequent urological disorder with a multifaceted etiology, yet the implication of visceral adiposity in its pathogenesis remains underexplored. Our objective was to evaluate the connection between the metabolic score for visceral fat (METS-VF) and OAB risk in a nationally representative USA population, besides comparing METS-VF predictive utility against conventional adiposity indices.
This cross-sectional analysis utilized National Health and Nutrition Examination Survey (NHANES) data from 6,366 participants. Multivariable logistic regression (LR) analysis, subgroup analyses, and receiver operating characteristic (ROC) were employed to ascertain the interaction of METS-VF with OAB. Furthermore, ROC analysis was implemented to contrast METS-VF diagnostic capabilities against body mass index (BMI), waist circumference (WC), and waist-to-height ratio (WHtR).
The analysis included 6,366 participants; of them, 4,536 were diagnosed with OAB, showing a significant link between METS-VF and OAB (P<0.001). Notably, OAB prevalence increased progressively across METS-VF quartiles (Q1: 52.20%, Q2: 64.76%, Q3: 74.56%, Q4: 85.19%). After full adjustment for covariates, METS-VF remained significantly related to OAB, revealing a positive association [odds ratio (OR) =1.38, 95% confidence interval (CI): 1.22-1.57]. Subgroup analyses consistently elucidated a significant interconnection between METS-VF and OAB across various demographics. The restricted cubic spline (RCS) analysis results demonstrated a significant non-linear association between METS-VF and OAB (P=0.004). Moreover, METS-VF displayed a superior predictive ability for OAB, unlike conventional indices, including BMI, WC, and WHtR.
The METS-VF, an innovative composite indicator of visceral adiposity and metabolic dysfunction, serves as a robust and reliable predictor of OAB risk among adults in the USA. Its enhanced predictive capacity relative to traditional adiposity metrics highlights its potential application in clinical risk assessment and public health strategies aimed at mitigating visceral obesity-related urological conditions.
