AWM: Interventions in Primary Care or Outpatient Settings (2020-21)

Intervention
In adults with overweight or obesity, what are adverse events of weight management interventions provided by an RDN or international equivalent in the primary care or outpatient setting, compared to usual care or no intervention from an RDN?
- Conclusion
  In adults with overweight or obesity, weight management interventions provided by a dietitian likely do not result in serious adverse events. Minor diet-related events such as dry skin or gastrointestinal symptoms were noted infrequently.
- Grade: Very Low (D)
  - 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.

In adults with overweight or obesity, what is the effect of weight management interventions provided by an RDN or international equivalent in the primary care or outpatient setting, compared to usual care or no intervention from an RDN, on fasting blood glucose?
- Conclusion
  In adults with overweight or obesity but without type 2 diabetes mellitus (T2DM), weight management interventions provided by a dietitian in a primary care/outpatient setting likely results in little to no difference in fasting blood glucose. However, interventions may improve fasting blood glucose for individuals with overweight or obesity and T2DM in a primary care/outpatient setting.
