Brief Summary

Chronic volume overload (VO) is a primary factor responsible for the excessive cardiovascular morbidity and mortality in hemodialysis (HD) patients. VO is caused in part by excessive fluid intake that is secondary to the consumption of a high salt diet. HD patients are often counselled to restrict their dietary sodium intake to help manage thirst and reduce their interdialytic weight gain (IDWG). However, data from recently published investigations demonstrate that dietary counseling alone may be ineffective. The objective of this randomized controlled trial is to determine if short-term feeding of low-sodium meals can "prime" changes in long-term nutrition behavior. It is hypothesized that feeding low-sodium meals for one month will significantly reduce IDWG and related outcomes, and continued dietary counseling and education support for 6 months will result in a sustained reduction in sodium intake upon patient resumption of meal responsibility. HD patients will be recruited and randomized to 2 groups: 1) Low-sodium meal feeding plus dietary counseling; or 2) a weight-list control group that will initially receive dietary counseling alone. IDWG will serve as the primary outcome with fluid volume overload, intradialytic hypotension, cramping, dietary sodium intake, sodium taste sensitivity and preference, and sodium self-efficacy evaluated at 1 and 6 months. This outcomes of this investigation will provide the first data on whether meal provision is an effective tool for dietary modeling and prolonged behavior change in HD patients.

Outcome Measures

Primary Outcomes (2)

  • Assessing Interdialytic weight gain (IDWG) using bioelectric impedance spectroscopy device (BIS)

    The research team will assess patients hydration status by using a non-invasive Cardiac System (NICaS) bioelectric impedance spectroscopy device (BIS) that will focus on noninvasive assessment and monitoring of cardiovascular, respiratory, and fluid parameters. The system provides real-time data on various parameters of a patient's cardiac and vascular functions. NICaS is a method of Impedance Cardiography (ICG) which utilizes dual impedance electrodes (about 3''x3''), placed on two limbs, preferably one on the wrist and the other on the contralateral ankle (any combination may work). NICaS measurements include the cardiac output and its derivatives, as well as an assessment of the left ventricular cardiac contractility. This device will be used to measure fluid retention between treatments.

    Five months

  • Blood Pressure - markers of cardiovascular risk

    The research team will use an IntelliSense® Blood Pressure Monitor to measure blood pressure accurately prior to dialysis treatment in quiet conditions with participants sitting rested for approximately 10 minutes. This measurement will take less than 2 minutes total to complete. The systolic blood pressure (mmHg) and diastolic blood pressure (mmHg) will be collected for this outcome.

Control

EXPERIMENTAL

Participants will follow their usual or normal diet for 5 months (CON) followed by an Controlled Dietary Sodium Restriction (INT) diet for 2 months. During the sodium restricted diet, participants will be provided with 2 meals and snacks daily, for 30 days (Month 5 - days 1-30) and 1 meal and snacks daily, for 30 days (Month 6 - days 31-60). These meals should meet the National Kidney Foundation's Kidney Disease Outcomes Quality Initiative (KDQOI) guidelines for energy and protein (30-35 kcal/kg \& 1.2 g/kg) as well as low phosphorus, potassium, and sodium. The meals are formulated to less than 600-800 mg sodium each (\<2,000g/day) and will be ordered and delivered through momsmeals.com

Intervention

EXPERIMENTAL

Participants will be provided with 2 meals and snacks daily, for 30 days (days 1-30) and 1 meal and snacks daily, for 30 days (days 31-60).

The meals are formulated to less than 600-800 mg sodium each (\<2,000g/day) and will be ordered and delivered through momsmeals.com

Eligibility Criteria

Age18 Years+
Sexall
Healthy VolunteersNo
Age GroupsAdult (18-64), Older Adult (65+)

You may qualify if:

  • Willingness to sign informed consent document and age 18 or greater.
  • High fluid gainer/excessive overloaded defined by: \> 3.0 % of estimated-dry weight (EDW)
  • No upper or lower limb amputations. This criteria is necessary because the BIS device we are using is not able to provide accurate estimates of fluid status in participants with limb amputations.
  • No pacemakers
  • Willingness to consume intervention meals provided throughout the study.
