Depressive symptoms linked to rapid decline in kidney function

Highlight

  • Among people with healthy kidneys, those who had more frequent depressive symptoms were more likely to show signs of rapid decline in kidney function over a median follow-up of 4 years.

Washington, DC (May 28, 2021) – In a study of adults with normal kidney function, those with frequent depressive symptoms were more likely to later experience a rapid decline in kidney function. The study will appear in a future issue of CJASN.

Depression is a common condition among middle-aged and older adults, and it can contribute to a variety of mental and physical problems. Previous research has found a link between depressive symptoms and rapid decline in kidney function in patients with chronic kidney disease (CKD). To look for a potential link in adults with normal kidney function, a team led by Xianhui Qin, MD (Nanfang Hospital, Southern Medical University, China) looked at information on 4,763 people with healthy kidneys when they enrolled in the China Health program and Longitudinal Retirement Study (CHARLS).

At the start of the study, 39% of participants had elevated depressive symptoms, and during a median follow-up of 4 years, 260 (6%) participants experienced a rapid decline in kidney function. There was a significant association between depressive symptoms at the start of the study and the rapid decline in kidney function during follow-up. Participants with frequent depressive symptoms were 1.4 times more likely to experience a rapid decline in kidney function than participants with infrequent depressive symptoms, after adjustments.

“CRF is one of the leading risk factors for cardiovascular disease, kidney failure and death worldwide. Therefore, identifying more modifiable risk factors can potentially reduce the enormous burden of it. CKD and its associated complications leading to early detection and prevention, “said Dr Qin. “Although our study does not show causation, it did show that high depressive symptoms were significantly associated with rapid decline in kidney function in Chinese adults with normal kidney function. If further confirmed, our data provide evidence for screening for depressive symptoms and effective psychosocial interventions to improve prevention of CRF. “
