Medical Nutrition Therapy

MNT: RDN in Medical Team (2015)

• Intervention
  What is the effectiveness of MNT (i.e., nutrition assessment, counseling and interventions) provided by a Registered Dietitian Nutritionist (RDN), when part of a healthcare team (i.e., transdisciplinary team, multi-disciplinary team)?

  • Conclusion
    Strong evidence supports the effectiveness of nutrition interventions and counseling provided by a nutrition professional (registered dietitian nutritionist or equivalent) when part of a health care team. Compelling evidence from 36 studies supports the multi-disciplinary team approach (including a nutrition professional) to improve weight (-0.3kg to -25.9kg), BMI (-0.5kg/m² to -14.6kg/m²), waist circumference (-1.0cm to -23.5cm), hip circumference (-2.8cm), fasting blood glucose (-1.6mg to -22mg per dL), HbA1c (-0.15% to -6%), fasting insulin (-3.7mcU to -7.7mcU per L), homeostatic model assessment-estimated insulin resistance (HOMA-IR; -1.0 units to -4.0 units), LDL-cholesterol (-6.0mg to -10mg per dL) and HDL-cholesterol (+2.0mg per dL) on a variety of health conditions (i.e., management of weight, eating disorders, diabetes, renal disease, amyotrophic lateral sclerosis (ALS), cardiovascular disease, osteoporosis).
  • Grade: I
    • 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.
  • Evidence Summary: What is the effectiveness of MNT (i.e., nutrition assessment, counseling and interventions) provided by a Registered Dietitian Nutritionist (RDN) when part of a healthcare team (i.e., trans-disciplinary team, multi-disciplinary team)?
