ObjectivesTo assess the impact of sarcopenia and vitamin D levels on the severity of lower urinary tract symptoms (LUTS).MethodsA total of 193 male patients, aged 60 years and above, who visited the geriatric outpatient clinic at Ibn-i Sina Hospital in Ankara, Turkey, between December 2019 and March 2021, were enrolled. Sarcopenia was diagnosed according to the criteria set by the European Working Group on Sarcopenia in Older People. The presence and severity of lower urinary tract symptoms were assessed using the International Prostate Symptom Score questionnaire, categorizing symptom severity as mild or moderate-to-severe.ResultsThe median patient age was 71 years (range: 66-77). Sarcopenia affected 24.9% of the population studied. Mild LUTS was observed in 43.5% and moderate-to-severe LUTS was observed in 56.5% of patients. Sarcopenia prevalence was significantly higher in the individuals with moderate-to-severe LUTS compared to those with mild-LUTS (p=0.021). After adjusting for Charlson comorbidity index and age, only vitamin D levels were significantly associated with increased odds of moderate-to-severe LUTS (odds ratio [OR]=0.95, 95% confidence interval [CI]: [0.92-0.98], p=0.002). Sarcopenia was not significantly associated with the severity of LUTS (OR=2.04, 95% CI: [0.94-4.45], p=0.070). An inverse linear trend was observed between quartiles of 25 (OH) vitamin D and LUTS severity. As 25 (OH)vitamin D levels increased, the proportion of patients with moderate-to-severe LUTS decreased (p=0.023).ConclusionSarcopenia did not significantly impact LUTS severity, but low vitamin D levels were associated with moderate-to-severe LUTS.Copyright: © Saudi Medical Journal.
