Association of Metabolic Syndrome Components and Overactive Bladder in Women

Association between body roundness index and overactive bladder: results from the NHANES 2005-2018

BACKGROUND AND AIM

An increasing amount of research has indicated obesity greatly affects individuals with overactive bladder (OAB). However, traditional anthropometric methods present challenges in accurately assessing the likelihood of OAB. Hence, this study's objective was to identify the correlation between the body roundness index (BRI) and OAB.

METHODS

The research included 12,401 individuals who participated in the National Health and Nutrition Examination Survey spanning 2005-2018. The correlation between BRI and OAB was explored by using weighted multiple logistic regression and weighted restricted cubic spline (RCS). Subgroup analyses showed the associations based on different population types. The study also analyzed the predictive capability of various anthropometric indices, including BRI, body mass index, waist circumference, and weight, in assessing the likelihood of OAB through Receiver-operating characteristic (ROC) curves.

RESULTS

An independent positive correlation between OAB and BRI was identified after adjusting for potential confounders in weighted multivariate logistic models[odds ratio (OR) = 1.15, 95% confidence interval (CI), 1.12-1.17]. Weighted RCS analysis found a positive dose-response correlation between OAB and BRI. The effect size of BRI on OAB remained stable across all prespecified subgroups (all P for interactions > 0.05). In ROC analysis, BRI showed better discriminatory ability for OAB compared with other anthropometric measures for both genders (all P < 0.01). The best BRI cutoff for predicting OAB was lower for men (5.151) than for women (5.383), suggesting that men were more susceptible to changes in BRI than women.

CONCLUSIONS

This study demonstrated that a raised BRI is correlated with a higher likelihood of OAB. Due to the effectiveness and non-invasiveness of BRI in predicting OAB, it is expected to become the preferred method for early detection and management strategies.

Increased prevalence of metabolic syndrome in female patients with overactive bladder: A population-based study

OBJECTIVES

To assess the association between overactive bladder syndrome (OAB) and the metabolic syndrome (MetS).

PATIENTS AND METHODS

A population-based study was conducted to compare OAB patients with age-, sex- and ethnicity-matched control subjects regarding the prevalence of the parameters of the MetS, with respect to obesity, hyperlipidemia, hypertension and diabetes mellitus. The characteristics of the OAB population were assessed. Adjusted odds ratios (OR) were calculated by logistic regression.

RESULTS

110 024 OAB patients and 220 455 controls. were identified. OAB was associated with a higher prevalence of MetS (35.4% vs. 27.5%, p < 0.001). The fully adjusted OR for MetS in patients with OAB compared to controls was 1.44; 95% confidence interval (CI) 1.42-1.46; p < 0.001. Among metabolic parameters, obesity was found to be the strongest factor associated with OAB (OR 1.55, 95% CI 1.53-1.58, p < 0.001), and higher high-density lipoprotein cholesterole levels (>50) had a protective effect on the risk of OAB (OR 0.75, 95% CI 0.73-0.76, p < 0.001).

CONCLUSIONS

Data from this cohort suggest that OAB is positively associated with MetS. Clinicians approaching patients with OAB should be aware of this association. A multimodal treatment focusing on the MetS may be considered in these patients.
