Abstract

Metabolic syndrome (MS) is a highly prevalent disease related to the risk of cardiovascular disease and diabetes. A large body of evidence has suggested a link between MS and the components of MS with lower urinary tract symptoms (LUTS) and benign prostatic hyperplasia (BPH) complex. The pathogenesis of MS is complex and not fully understood. Furthermore, recent results from epidemiological studies, including multiple Asian reports, have not been consistent. The risk of BPH is lower in Asian men compared with white men and the prevalence of MS varies by race and ethnicity. An elevated risk of Type 2 diabetes mellitus, hypertension, and dyslipidaemia is closely related to MS and is observed in Asian men even if their body mass index is low. However, the role of race and ethnic disparity in the link between MS and LUTS secondary to BPH is not elucidated. It has been suggested that the pathogenesis of LUTS is multifactorial rather than developing from BPH, which is the traditional concept. Lifestyle and genetic factors may substantially modify the risk of MS and LUTS/BPH. This comprehensive literature review summarises the scientific evidence of the racial/ethnic disparity regarding the association between MS and LUTS/BPH in
order to improve current understanding of this controversial issue.
