Hypothesis

What strategies have been evaluated to disseminate cancer control interventions that promote the uptake of a healthy diet in adults?

Conclusion

No beneficial dissemination strategies were found, but one involving peer educators showed promise in increasing fruit and vegetable intake.

Supporting Evidence

  • Four studies were randomized trials, but most were rated methodologically weak.
  • One strategy using peer educators led to a short-term increase in fruit and vegetable intake.
  • Media campaigns increased awareness but were expensive to maintain.

Takeaway

This study looked at ways to help people eat healthier to prevent cancer, but found that most methods didn't work well, except for one that used peer educators.

Methodology

A systematic review of primary studies evaluating dissemination strategies for dietary interventions.

Potential Biases

Many studies had methodological weaknesses and potential biases in participant selection.

Limitations

The quality of the evidence is not strong, and the studies were mostly descriptive rather than evaluative.

Participant Demographics

Studies were conducted in the United States, targeting adults and health care providers.
