| Abstract: | BackgroundTo investigate the association between lower urinary tract symptoms suggestive of benign prostate hyperplasia (LUTS/BPH) and metabolic syndrome (MetS) in aging Chinese males.MethodsA dataset that included 3,568 non-MetS cases and 1,020 MetS cases (after data cleansing) was downloaded from the China Health and Retirement Longitudinal Study (CHARLS). To balance the intergroup covariates, propensity score matching (PSM) was employed in the analyses. Univariate logistic regression and multivariate logistic regression were then performed to investigate the relationship between LUTS/BPH and MetS in aging Chinese males.ResultsBefore PSM, multivariate logistic regression showed that participants with MetS had a 1.47 times higher risk of LUTS/BPH compared to non-MetS cases in the final model (P<0.001). It also revealed that participants with low high-density lipoprotein (HDL), abdominal adiposity, or high triglycerides had a higher probability of LUTS/BPH odds ratio (OR) =1.56 for low HDL; OR =1.50 for abdominal adiposity; and OR =1.48 for high triglyceride, P<0.001], while participants with hyperglycemia or hypertension had identical odds of LUTS/BPH (P>0.05). After PSM, 1,000 pairs were successfully matched. It was also found that MetS cases had a 1.60 times higher risk of LUTS/BPH compared to non-MetS cases (P<0.001), and participants with low HDL, abdominal adiposity, high triglycerides, or hyperglycemia had a higher likelihood of LUTS/BPH than their counterparts (P<0.001). However, the probability of LUTS/BPH in hypertensive patients remained similar to that in non-hypertensive patients (P>0.05).ConclusionsAging Chinese males with MetS had a higher probability of LUTS/BPH. Also, patients with low HDL, abdominal obesity, high triglycerides, or hyperglycemia had an increased risk of LUTS/BPH; however, this was not the case for hypertensive patients. |
