LUTS/BPH increases the risk of depressive symptoms among elderly adults: A 5-year longitudinal evidence from CHARLS.

ABSTRACT

OBJECTIVE: The prevalence of Lower Urinary Tract Symptoms suggestive of Benign Prostatic Hyperplasia (LUTS/BPH) is notably high and potentially elevates the likelihood of depressive symptoms. This study was designed to employ both cross-sectional and longitudinal methodologies to explore the correlation between LUTS/BPH and depressive symptoms among middle-aged and elderly men in China. METHODS: This investigation utilized data from the China Health and Retirement Longitudinal Study (CHARLS), with the initial dataset from 2015 serving as the baseline and subsequent data from 2018 and 2020 facilitating longitudinal analysis. The study encompassed a baseline cohort of 5156 men aged 45 years and above, and an expansive longitudinal analytical sample of 23,530 participants spanning from 2015 to 2020. The assessment of depressive symptoms was conducted using the 10-item Center for Epidemiological Studies Depressive Symptoms Scale (CESD-10). To investigate the factors associated with LUTS/BPH, the relationship between LUTS/BPH and depressive symptoms, and to evaluate the incidence rate of depressive symptoms onset based on LUTS/BPH status, multivariate logistic analyses and logistic regression models were employed. RESULTS: Our results reveal a markedly higher incidence of depressive symptoms among individuals with LUTS/BPH, at 30.16 %, compared to 22.94 % in those without LUTS/BPH. This pattern was consistent in both mild and moderate depressive symptoms categories. However, the prevalence of severe depressive symptoms did not exhibit a significant disparity between the two groups. Longitudinal analysis spanning from 2015 through 2018 and 2020 further corroborated these observations. Individuals with LUTS/BPH showed a substantially higher incidence of depressive symptoms across all severity levels compared to those without LUTS/BPH. Specifically, the presence of LUTS/BPH was linked to a 53 % heightened risk of mild depressive symptoms, a 45 % increase in moderate depressive symptoms, and an alarming 229 % surge in severe depressive symptoms risk between 2015 and 2018. Additionally, from 2015 to 2020, there was a 30 % increased risk for mild depressive symptoms, a 41 % rise for moderate depressive symptoms, and a 106 % escalation in the risk of severe depressive symptoms among those with LUTS/BPH. CONCLUSION: In middle-aged and older Chinese adults, LUTS/BPH were correlated with an elevated risk of depressive symptoms.
