Eksperimentel: SCT-based behavioral intervention
Intervention participants continue to receive routine dialysis care, as well as a 16 week dietary counseling intervention based on Social Cognitive Theory.
Dietary counseling is paired with Personal Digital Assistant-based dietary self-monitoring.
|
Intervention group continues to receive routine dialysis care.
The intervention duration is 16 weeks.
Intervention contacts are 2x/week for weeks 0-8, weekly for weeks 9-12, and every other week for weeks 13-16.
Personal digital assistant dietary records are use to provide targeted counseling and engaged the participant in problem solving around dietary issues.

Aktiv komparator: Attention control
Attention control participants continue to receive routine dialysis care.
Attention control participants view 5 computerized educational programs PowerPoint slides) that summarize the various elements of the HD diet.
The 5 modules evenly over the 4-month study period.

Time Specific Dietary Sodium Intake (Baseline)
Tidsramme: Baseline
|
Dietary sodium intake was assessed via three 24-hour dietary recalls, including 1 dialysis weekday, 1 non-dialysis weekday, and 1 non dialysis weekend day.
Recalls were entered into Nutrition Data System for Research, with sodium intake averaged across the 3 recalls.
