This study evaluated the effectiveness of a low-intensity dietary intervention in primary care practice in lowering dietary fat intake and raising dietary fiber intake.
A randomized controlled trial of 28 physician practices in six primary care clinics enrolled, by telephone, adult patients who had appointments for nonurgent non-acute visits.
Of 3490 eligible patients contacted, 2111 completed baseline interview ; 86.1% also completed a 12-month follow-up.
Physicians gave intervention participants a self-help booklet and a brief motivational message.
Changes in fat and fiber from baseline to 12-month follow-up were evaluated.
Intervention and control groups both reported a decrease in fat intake and an increase in fiber intake.
The differential change and 95% confidence interval (Cl) for the percentage of energy obtained from fat was - 1.2 (Cl=-0.71. - 1.7) (P=0015), for grams fiber/1000 kcal 0.32 (Cl=-0.066,0.71) (P=086), for fat score - 0.044 (Cl=-0.016, - 0.072) (P=010), and for fiber score 0.036 (Cl=0.011,0.061) (P=014), with greater reductions in fat and greater increases in fiber in the intervention group.
This low-intensity intervention was effective in dietary behavior change.
