Area of Science:

  • Public Health
  • Preventive Medicine
  • Behavioral Science

Background:

  • Dietary fat intake and low fiber consumption are linked to chronic diseases.
  • Primary care settings offer opportunities for lifestyle interventions.
  • Effective, low-intensity interventions are needed to promote healthier eating habits.

Purpose of the Study:

  • To evaluate a low-intensity dietary intervention's effectiveness in primary care.
  • To assess changes in dietary fat and fiber intake among adult patients.

Main Methods:

  • A randomized controlled trial was conducted across 28 physician practices in six primary care clinics.
  • Adult patients attending non-urgent visits were enrolled; 2111 completed baseline and 12-month follow-ups.
  • Intervention group received a self-help booklet and motivational message; control group received usual care.

Main Results:

  • Both groups showed reduced fat intake and increased fiber intake.
  • The intervention group demonstrated statistically significant greater reductions in fat intake (P = .0015) and greater increases in fiber intake (P = .014).
  • Differential changes favored the intervention group for fat score (P = .010) and fiber score (P = .014).

Conclusions:

  • A low-intensity dietary intervention delivered in primary care is effective.
  • This intervention successfully promoted positive dietary behavior change.
  • The findings support the integration of brief dietary counseling in routine primary care.
