Predictors of dietary and fluid non-adherence in Jordanian patients with end-stage renal disease receiving haemodialysis: a cross-sectional study.J Clin Nurs. 2013 Jan; 22(1-2):127-36.JC
AIMS AND OBJECTIVES
The purpose of this study is to provide insight into the relationship between dietary and fluid non-adherence, depressive symptoms, quality of life, perceived barriers and benefits of exercise, and perceived social support among Jordanian patients with end-stage renal disease receiving haemodialysis using Pender's health promotion model.
Non-adherence to dietary and fluid restrictions is a leading cause of treatment failure and poor outcomes in end-stage renal disease. Yet, factors that interfere with the patients' ability to follow their dietary restrictions are unknown.
A descriptive, correlational, cross-sectional design was used.
Jordanian patients (n = 190) with end-stage renal disease receiving haemodialysis from three main Jordanian cities were included. The dialysis diet and fluid nonadherence questionnaire, Beck Depression Inventory-II, Quality Of Life Index, Dialysis Patient-Perceived Exercise Benefits and Barriers Scale, and the Multidimensional Perceived Social Support were employed to measure the key variables.
Patients were more likely men with mean age of 48·2 ± 14·9. Only 27% of the patients showed full commitment to diet guidelines and 23% to fluid guidelines during the last 14 days. Depression (M = 18·8 ± 11·4) had significant negative association with quality of life (importance and satisfaction) (r = -0·60, r = -0·32, p = 0·001, respectively). Multiple hierarchal regressions revealed a predictive model of only two variables: age (B = -0·22, p = 0·05) and residual renal function (B = -0·23, p = 0·012) for dietary non-adherence.
Non-adherence to diet and fluid guidelines association with individual characteristics, health perception and psychosocial variables should be investigated in a longitudinal design. Relationship of non-adherence with culture-related factors should deeply be assessed among Jordanian patients with end-stage renal disease receiving haemodialysis.
RELEVANCE TO CLINICAL PRACTICE
Identification of the factors that may worsen dietary and fluid non-adherence may lead to improved therapeutic interventions within the mainstream of medical practice for Jordanian patients with end-stage renal disease receiving haemodialysis.
