Objective:
To test the effectiveness of a minimal nutrition intervention to increase dietary intake of folate.
Method:
Randomised controlled trial in the general practice setting of personalized, face-to-face feedback with educational materials to increase dietary intake of folate.
Results:
One hundred and nine intervention and 94 control subjects completed baseline and follow-up assessments within the study period. At baseline (August-October 2004), there were no significant differences in folate intake scores between the intervention and control groups. At the eight-week follow-up, the mean folate intake score in the intervention group was significantly higher than in the control group, indicating that the nutrition intervention significantly increased reported dietary intake of folate.
Conclusion:
Presenting individual dietary feedback in conjunction with educational materials in the general practice setting is an effective way of changing dietary behaviour.
Implications:
The present study suggests a way in which health-related dietary change may be encouraged on a large scale without incurring a large cost.
