Methods: In this feasibility study, free-living older adults (n = 180; means = 67.5 years old) were randomly assigned to one of three levels of a 3-month standardized compliance enhancement program.
Results: Regarding subject compliance with the 18 g/day wheat bran fiber supplement, the high compliance enhancement group had a superior regimen compliance rate (88%) versus the medium and low groups, (66 and 29%, respectively) (P = 0.01), with similar attrition rates.
Conclusion: No significant gastrointestinal side effects and changes in body weight were reported. For similar efficacy, the comprehensive compliance enhancement group had the greatest cost effectiveness.
