BackgroundThe association between the triglyceride-glucose (TyG) index and mortality in the general population remains controversial, with inconsistent findings across studies.ObjectiveThis study aims to investigate the relationship between the TyG index and mortality in the U.S. Additionally, it explores whether a new index, combining the TyG index with the neutrophil-to-lymphocyte ratio (NLR), improves the prediction of all-cause compared to the TyG index alone.MethodsSystemic inflammatory markers and the TyG index were calculated based on participants’ complete blood counts and fasting triglyceride and glucose levels. The TyG-NLR index was derived by multiplying the TyG index by the NLR. A weighted Cox proportional hazards model was used to evaluate the associations of the TyG and TyG-NLR indices with mortality risk in the general population. Restricted cubic splines (RCS) were applied to explore and visualize the dose-response relationships between the indices and mortality.ResultThis study included 15388 participants. During a median follow-up of 118 months, 2,333 participants died. After adjusting for potential confounders, no significant association was found between the TyG index and mortality. However, compared to the lowest quartile, participants in the highest quartile of the TyG-NLR index showed a significant association with all-cause mortality. Specifically, those in the highest quartile had a 63% higher risk of all-cause mortality.

BackgroundUrinary incontinence (UI), particularly urge urinary incontinence (UUI), is a prevalent condition that worsens with age and negatively affects quality of life. Antioxidants, measured by the composite dietary antioxidant index (CDAI), have been linked to inflammation and other diseases, but their relationship with UUI remains uncertain. The purpose of this study is to investigate the relationship between UUI prevalence and CDAI.Materials and methodsData for this cross-sectional study were obtained from the National Health and Nutrition Examination Survey’s four cycles (2011–2018). The odds ratio (OR) and 95% confidence interval (95% CI) of the relationship between CDAI and male UUI were ascertained by the use of weighted univariate analysis, multivariate logistic regression, restricted cubic spline regression, and subgroup analysis. PSM and sensitivity analyses were performed to assess the robustness of the findings.ResultsA total of 7,735 participants took part in this study. After adjusting for potential confounders, CDAI was found to be negatively associated with the prevalence of UUI in those with lower CDAI (about half overall). This relationship lost significance in populations with higher CDAI. The negative correlation between zinc and the prevalence of UUI was more significant in populations with low antioxidant diets. The results remained consistent, with subgroup analyses finding a significant interaction effect for race only after PSM (p = 0.043), with no significant interaction effect observed for the rest.ConclusionThis study showed a negative correlation between CDAI and UUI incidence in the group of men with low CDAI levels (about half of the population). Thus, effective prevention or treatment of UUI requires dietary changes aimed at the male population with poor antioxidant diets.
