Chronic Pain and Its Association with Depressive Symptoms and Renal Function in Hypertensive Patients

Chronic pain is a common concern and is considered to be one of the major problems in patients with chronic physical disorders. We studied the effect of pain in patients with hypertension with or without chronic kidney disease (CKD) and the association between pain and symptoms of depression. The study involved 158 hypertensive individuals (59.5% male, mean age 55 years), of whom 47 (29.8%) had CKD (estimated glomerular filtration rate < 60 mL/min/1.73 m(2)). Pain was assessed with the pain/discomfort domain of the EuroQol-5 D, while depressive symptoms were assessed with the depression module of the Patient health questionnaire (PHQ-9). The prevalence of chronic pain in our sample was 44.3%. Women exhibited chronic pain more often compared to men (57.1% vs. 42.9%, p < 0.001). The presence of CKD was not significantly associated with a higher prevalence of chronic pain among hypertensive patients. Depressive symptoms were significantly associated with the presence of chronic pain. These findings were confirmed in the logistic regression analysis. Chronic pain is common in hypertensive individuals and the association with depression warrants further investigation and may have practical implications in managing these patients.
