Show moreRationale & Objective: Patients with chronic kid-ney disease (CKD) not receiving dialysis, including kidney transplant recipients, often experience diffi-culties regarding self-management. An important barrier for adherence to self-management recommendations may be the presence of psychological distress, consisting of depressive and anxiety symptoms. We investigated relationships between psychological distress and adherence to self-management recommendations. Study Design: Cross-sectional online question-naire data as part of the E-GOAL study. Setting & Participants: Patients with CKD (esti-mated glomerular filtration rate, 20-89 mL/min/ 1.73 m2) were recruited from April 2018 to October 2020 at 4 hospitals in The Netherlands and completed online screening questionnaires. Exposures: Psychological distress, depressive symptoms, and anxiety symptoms. Outcomes: Dietary adherence, physical activity, medication adherence, smoking, body mass index, and a CKD self-management index (ie, the sum of 5 binary indicators of nonadherence to the recommended self-management factors). Analytical Approach: Adjusted multivariable regression and ordinal logistic regression analyses. Results: In our sample (N = 460), 27.2% of pa-tients reported psychological distress, and 69.8% were nonadherent to 1 or more recommendations. Higher psychological distress was significantly associated with poorer dietary adherence (3adj, -0.13; 95% CI, -0.23 to -0.0 4), less phys-ical activity (3adj, -0.13; 95% CI, -0.22 to -0.03), and lower medication adherence (3adj, -0.15; 95% CI, -0.24 to -0.05), but not with smoking and body mass index. Findings were similar for depressive symptoms, whereas anxiety was only associated with poorer dietary and medication adherence. Every 1-point higher psychological distress was also associated with a higher likelihood of being nonadherent to an accumulating number of different recommendations (adjusted OR, 1.04; 95% CI, 1.02-1.07). Limitations: Cross-sectional design, possible re-sidual confounding, and self-report. Conclusions: Many people with CKD experience psychological distress, of whom most have diffi-culties self-managing their CKD. Given the relationship between psychological distress and adherence to CKD self-management recommendations, behavioral interventions are needed to identify and treat psychological distress as a potential barrier to CKD self-management.
