Background

Kidney stone disease (KSD) is associated with significant morbidity and may negatively impact psychosocial well-being. Here, we evaluated the association between KSD and depression to determine the prognostic significance of depression on mortality in this unique patient population.

Methods

We analyzed 23,051 adults from NHANES 2007-2018 database, including 2,241 individuals with KSD. Depression was assessed using PHQ-9, a validated diagnostic tool to assess depression severity. Ordinal logistic regression examined the association between KSD and depression. Cox regression models evaluated the association between depression severity and all-cause mortality (ACM) and cardiovascular mortality (CVM), adjusting for demographic and clinical factors (Table).

Results

Moderate-to-severe (ms) depression (PHQ-9≥10) was present in 280/2,241 kidney stone formers (KSF) and 1,797/20,810 non-KSF. Regression analysis showed that KSF had higher odds of depression compared with non–KSF (adjusted OR 1.14; 95% CI, 1.00–1.30). This association was significant in women (adjusted OR 1.32; 95% CI, 1.10–1.59; p=0.004), but not in men (adjusted OR 1.03; 95% CI, 0.87–1.22; p=0.72). No effect modification by age was observed.
There were 316 all-cause deaths and 71 cardiovascular deaths among KSF in this cohort, compared with 1,941 and 472 deaths, respectively, among non-KSF. Among non-KSF, individuals with ms-depression had significantly increased risks of ACM (adjusted HR [aHR] 1.76; 95% CI, 1.43–2.16; p<0.001) and CVM (aHR 2.24; 95% CI, 1.14–2.60; p<0.001). In contrast, among stone formers, ms-depression was significantly associated with ACM (aHR 1.99; 95% CI, 1.24–3.21; p=0.005), but not with CVM (aHR 1.61; 95% CI, 0.60–4.32; p=0.34).

Conclusion

KSD is associated with an increased risk of depression, particularly in women. Depression severity predicts ACM, but not CVM, after adjustment for cardiovascular risk factors. These findings underscore the need for integrated mental health management strategies to improve outcomes in KSD.
