Association of Serum Triglyceride and Stress Urinary Incontinence in Women From the National Health and Nutrition Examination Survey: A Cross-Sectional Study

Association between Life's essential 8 and stress urinary incontinence in women from the National Health and nutrition examination survey 2005-2018: A cross-sectional study

OBJECTIVE

Stress urinary incontinence (SUI) may be associated with cardiovascular disease. Life's Essential 8 (LE8), a recently updated measure of cardiovascular health (CVH), has been investigated for its association with SUI in women.

METHODS

The study adopted a cross-sectional design with national scope, incorporating 9332 women aged 20 and above, selected from the National Health and Nutrition Examination Survey dataset from 2005 to 2018. The LE8 metric, which varies from 0 to 100, was evaluated based on the criteria set by the American Heart Association. SUI was determined based on self-report. To evaluate these correlations, we employed models with multivariable logistic variables and a restricted cubic spline.

RESULTS

In the cross-sectional study, a total of 9332 participants were included (weighted average age, 52.23 years), and 4274 had SUI (weighted percentage, 48.64%). Considering potential confounders, it was found that higher LE8 scores were associated with lower odds of SUI (odds ratio [OR] for each 10-point increase was 0.83; 95% confidence interval [CI], 0.80-0.87). Compared to participants with lower LE8 scores, those with higher LE8 scores had a 57% lower probability of developing SUI. There was a statistically significant association between LE8 score and SUI among participants who were middle-aged, non-Hispanic white, had higher levels of education and income, and were living with a partner.

CONCLUSION

According to this study, there was an association between increase in Life's Essential 8 and reduction in SUI risk. Therefore, promoting optimal CVH may associate with reducing SUI in women.

Apo E protein and related markers show the prognosis of stress urinary incontinence rats treated with modified Buzhong Yiqi Decoction

Stress urinary incontinence (SUI) is a common disease that seriously affects the quality of life of patients. In recent years, studies have shown that apolipoprotein E (ApoE) plays a role in neuroprotection and repair, but its specific role in SUI remains unclear. The aim of this study was to investigate the effect of macromolecular protein ApoE related markers on the prognosis of rats with SUI treated by modified Buzhong Yiqi Decoction (MBZYQD), in order to provide a new target for the treatment of SUI. Healthy rats were selected to establish a SUI model and divided into groups. The levels of ApoE related metabolites in blood of rats were detected by Metabolomics analysis and Lipidomics analysis. The urine leakage point pressure (LPP) were compared in each group, and the therapeutic effect of MBZYQD was evaluated. Compared with the model group, the LPP of rats in MBZYQD supplemented group was significantly higher. Compared with the control group, the LPP of MBZYQD was not statistically significant before and after treatment. The macromolecular protein ApoE may plays a key role in the treatment of SUI by MBZYQD, which can improve symptoms by regulating lipid metabolism repair.

Association between exposure to multiple metals and stress urinary incontinence in women: a mixture approach

There is limited evidence linking exposure to heavy metals, especially mixed metals, to stress urinary incontinence (SUI). This study aimed to explore the relationship between multiple metals exposure and SUI in women. The data were derived from the National Health and Nutrition Examination Survey (NHANES), 2007-2020. In the study, a total of 13 metals were analyzed in blood and urine. In addition, 5155 adult women were included, of whom 2123 (41.2%) suffered from SUI. The logistic regression model and restricted cubic spline (RCS) were conducted to assess the association of single metal exposure with SUI risk. The Bayesian kernel machine regression (BKMR) and weighted quantile sum (WQS) were used to estimate the combined effect of multiple metals exposure on SUI. First, we observed that blood Pb, Hg and urinary Pb, Cd were positively related to SUI risk, whereas urinary W was inversely related by multivariate logistic regression (all p-FDR < 0.05). Additionally, a significant non-linear relationship between blood Hg and SUI risk was observed by RCS analysis. In the co-exposure models, WQS model showed that exposure to metal mixtures in blood [OR (95%CI) = 1.18 (1.06, 1.31)] and urine [OR (95%CI) = 1.18 (1.03, 1.34)] was positively associated with SUI risk, which was consistent with the results of BKMR model. A potential interaction was identified between Hg and Cd in urine. Hg and Cd were the main contributors to the combined effects. In summary, our study indicates that exposure to heavy metal mixtures may increase SUI risk in women.
