What the CPSTF Found

About The Systematic Review

The Task Force finding is based on evidence from a systematic review of 4 studies (search period 1966 to June 30, 2007).

The review was conducted on behalf of the Task Force by a team of specialists in systematic review methods, and in research, practice, and policy related to obesity prevention and control.

Context

There is no information for this section.

Summary of Results

Detailed results from the systematic review are available in the Task Force finding pdf icon [PDF - 120 kB].

Four studies were included in the review.

Providers for adult populations (3 studies)

  • All studies reported non-significant increases in knowledge, attitudes, and skills among providers working with adult patients.
    • Providers trained in motivational interviewing were more likely to be empathic and let their patients talk more (1 study).
    • Providers’ knowledge and self-efficacy increased at 6-month follow-up (1 study).
    • Patients’ weight-related outcomes did not change at 6-month follow-up (1 study).

Providers for children (1 study)

  • There was a non-significant effect on children’s BMI percentile at 6-month follow-up (effect estimate = ‑0.02 minimal group; ‑0.03 intensive group).

Summary of Economic Evidence

An economic review of this intervention was not conducted because the Task Force did not have enough information to determine if the intervention works.

Applicability

Applicability of this intervention across different settings and populations was not assessed because the Task Force did not have enough information to determine if the intervention works.

Evidence Gaps

Additional research and evaluation are needed in these areas, to fill existing gaps in the evidence base.

Effectiveness on provider outcomes:
  • What effect do interventions have on providers' knowledge, attitudes, skills, and behavior?
  • Do interventions have an additional benefit on the provider's own weight?
  • Which characteristics of the interventions contribute to increased or decreased effectiveness?
  • Do different methods of delivery to providers produce different results?
  • What frequency, duration, or format of provider education contributes to increased or decreased effectiveness?
  • Are provider-based interventions more effective at preventing weight gain, preventing weight re-gain, or promoting weight loss?
Effectiveness on patient outcomes:
  • If the provider interventions change their knowledge, attitudes, and skills, does this have an effect on patient knowledge, attitudes, and skills?
  • Do provider-level interventions have an effect on patient biological outcomes (such as weight-related outcomes, objectively measured)?
  • Do intervention effects vary when delivered to subgroups or sub-populations?
Implementation and adoption:
  • Are provider-level interventions more effective when used within clinical systems than when patients are referred to providers outside the system?
  • Do specific benefits of an intervention enhance its acceptability? For example, does training providers on obesity counseling assist with other types of counseling?
  • Are there other harms from an intervention, such as taking provider time away from other tasks that might be more effective?
  • What is the cost effectiveness of these interventions?
  • How broadly applicable is the intervention; to what types of patients does it apply?
  • What resources (e.g., time, money, staffing, computer capabilities) constrain these interventions?
  • In what ways can interventions be integrated into institutional or other system-level interventions?
  • Does effectiveness differ by the type of provider?
  • Does the level of scale affect whether interventions work?

Study Characteristics

  • No studies with adult patients reported effects on providers’ screening, referral, or treatment for obesity.
  • The one study with pediatric patients did not report on provider behavior, knowledge, attitudes, or skills.
