Chronic kidney disease (CKD) is a global public health problem involving increased risk of cardiovascular disease (CVD) and premature death. Psychosocial explanations of health involving social, psychological and physiological processes all interact to affect the aetiology and development of CKD.[1] For example, social processes such as social support may lead to psychological changes at the individual level which may influence health directly via physiological processes or modified behaviours.[2] Psychosocial factors are important both because they have an

impact on quality of life and have been shown to influence the progression of various chronic diseases.[3, 4] However, our understanding of the burden and impact of these potentially modifiable risk factors in CKD is limited. Rates of CKD are increasing in Australia buy Panobinostat Kinase Inhibitor Library high throughput with the number of patients commencing renal replacement therapy (RRT; dialysis or transplantation) between 1990 and 2009 escalating by 321%.[5] In addition to those being treated, around 36% of people with advanced CKD are not being dialysed[6] and a similar proportion are dying via withdrawal from dialysis.[7] In light of this increasing social and economic burden, examining the role of potentially modifiable non-biological risk factors on the disease trajectory of CKD should

be a priority. This paper examines the prognostic role of several key psychosocial factors (depression, anxiety and perceived social support) and health-related quality of life (HRQOL) in adults with CKD (i.e. CKD stage 1–5, unless otherwise stated) prior to RRT. We explore current gaps in the literature and examine potential mechanisms through which these factors may affect health outcomes. Potential interventions and suggestions for future research are also outlined. Depression is a chronic and recurrent illness associated with substantial morbidity 3-oxoacyl-(acyl-carrier-protein) reductase and all-cause mortality. Comorbid depressive disorders in patients with chronic disease reduce quality of life, and increase functional disability and use of healthcare services.[8] Unemployment,

low income, low perceived social support, and changes in familial and occupational roles are recognized risk factors for depression in people with CKD.[9-12] While identifying depression in patients with kidney disease is complicated by the potential misclassification of uraemic symptoms as somatic symptoms of depression, prevalence estimates for clinical depression in dialysis patients (CKD 5D) range from 20% to 30%.[13, 14] Similarly, around 22% of individuals with pre-dialysis CKD fulfil the criteria for major depression[15, 16] while 37–55% report depressive symptoms.[16-18] This is higher than the prevalence of depressive disorders in the general population (7%)[9] and in those with other chronic diseases including cancer (11%).
