Samenvatting

Renal transplant recipients (RTR) are at risk of decline of graft function and premature mortality, with high blood pressure as important risk factor for both. To study the association of the Dietary Approach to Stop Hypertension (DASH) diet with these adverse events, we conducted a prospective cohort study of adult RTR. Dietary data was collected using a validated 177-item food frequency questionnaire and an overall DASH-score was obtained. We included 632 stable RTR (mean±SD age: 53.0±12.7 y, 57% men). Mean DASH score was 23.8±4.7. During median follow-up of 5.3 (IQR, 4.1-6.0) y, 119 (18.8%) RTR had renal function decline, defined as a combined endpoint of doubling of serum creatinine and death-censored graft failure, and 128 (20.3%) died. In Cox-regression analyses, RTR in the highest tertile of the DASH score had lower risk of both renal function decline (HR=0.57; 95%CI: 0.33-0.96, p=0.03) and all-cause mortality (HR=0.52; 95%CI: 0.32-0.83, p=0.006) compared to the lowest tertile, independent of potential confounders. Adherence to a DASH-style diet is associated with lower risk of both renal function decline and all-cause mortality. These results suggest that a healthful diet might benefit long-term outcome in RTR. This article is protected by copyright. All rights reserved.
