NCT01738607

Brief Summary

The primary aim of this study was to compare the effects of supplementation with one of three dietary fibers (gum arabic, carboxy-methylcellulose, or psyllium) or a placebo on fecal incontinence (FI), symptom intolerance, and quality of life in community-living individuals who have incontinence of loose or liquid feces. A secondary aim was to explore the possible mechanism(s) underlying the supplements' efficacy (i.e., improvements in stool consistency, water-holding capacity or gel formation).

Outcome Measures

Primary Outcomes (1)

  • self-report of an incontinent episode on a daily stool diary

    the date and time of an incontinence episode was reported and the ratio of the number of incontinence episodes to total stools daily was calculated

Secondary Outcomes (8)

  • self-report of gastro-intestinal symptoms on a daily symptom record

  • self-report of quality of life

  • Water-holding capacity of non-frozen of stools

  • Gel formation of non-frozen stools

  • Total dietary fiber content of feces

  • +3 more secondary outcomes

Other Outcomes (10)

  • self-reported rating of consistency of continent stools on a daily stool diary

  • usual diet intake

  • report of additional fluid intake

  • +7 more other outcomes
