Aim: To evaluate feasibility and acceptability of a self-efficacy-based dietary intervention (Kidney-HELP) aimed at improving diet quality in adults with chronic kidney disease (CKD).
Background: Poor diet quality is common in CKD and is associated with disease progression and mortality. Interventions targeting self-efficacy may improve diet quality, however, the optimal intervention intensity required is unclear.
Methods: Adults with CKD stage 3-4 attending nephrology clinics in Southeast Queensland (April-October 2024) were randomised 1:1 to a high-intensity group program (Group) or low-intensity self-paced program (Self-paced). Kidney-HELP focused on goal setting, self-monitoring, mindful eating and promoting a healthy dietary pattern aligned with the Australian Dietary Guidelines and Heart Foundation dietary recommendations. Feasibility was measured by recruitment (≥35%), retention (≥80%) and adherence to program (≥50%). Acceptability was evaluated using content analysis of semi-structured interviews (n=14). Secondary outcomes were dietary adherence, diet quality, and dietary self-efficacy. Descriptive statistics and paired or independent t-tests (or non-parametric equivalents) were used.
Results: Of 298 eligible patients, 50 (17%) were recruited. Retention at 12 weeks was 52% (Group) and 80% (Self-paced), with adherence rates of 48% and 68%, respectively. Both formats were acceptable: content was easy to understand, flowed logically; and telehealth and self-paced delivery improved accessibility. Improvements in dietary adherence were observed in both groups (Group: MD 2.5 [95% CI 0.1, 4.9]; Self-paced: MD 2.0 [95%CI 0.7, 3.2]), while only Self-paced group improved dietary self-efficacy (MD 1.7 [95%CI 0.1, 3.3]). There were no significant changes in diet quality.
Conclusions: Self-paced Kidney-HELP was more feasible and is an acceptable intervention that removes barriers to access. A large-scaled effectiveness implementation trial of Self-paced Kidney-HELP is required to confirm health outcomes.
