  • Assessment
    What is the evidence to support effectiveness of MNT provided by an RD compared with other healthcare professionals who provide nutrition interventions (doctors, nurses, health coaches, etc.)?
    • Conclusion

      Five studies were reviewed to evaluate the effectiveness of Medical Nutrition Therapy (MNT) provided by a registered dietitian, when compared with other healthcare professionals who provide nutrition interventions in the same study. The only studies comparing providers were in the area of hyperlipidemia: These studies report inconclusive findings due to variations in nature and length of the interventions and outcome measures. Further research utilizing comparable interventions on consistent outcomes over longer time periods is needed, as well as research in other disease states and compared with other healthcare professionals.

    • Grade: III
      • Grade I means there is Good/Strong evidence supporting the statement;
      • Grade II is Fair;
      • Grade III is Limited/Weak;
      • Grade IV is Expert Opinion Only;
      • Grade V is Not Assignable.
      • High (A) means we are very confident that the true effect lies close to that of the estimate of the effect;
      • Moderate (B) means we are moderately confident in the effect estimate;
      • Low (C) means our confidence in the effect estimate is limited;
      • Very Low (D) means we have very little confidence in the effect estimate.
      • Ungraded means a grade is not assignable.
    What is the evidence to support effectiveness of nutrition interventions and counseling provided by an RD when part of a healthcare team?
    • Conclusion

      Nine studies demonstrate that the inclusion of nutrition interventions and counseling, when provided by a registered dietitian as part of a healthcare team, resulted in significant improvements in weight and BMI, A1C, blood pressure and serum lipids. The majority of these studies took place in primary care settings.
