研究概览
简要总结
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).

结局指标
主要结局
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
次要结局
- self-report of gastro-intestinal symptoms on a daily symptom record
- Total dietary fiber content of feces
- wet and dry weights of collected stools and percentage of water content
- Gel formation of non-frozen stools
- amount of fecal incontinence
- self-report of quality of life
- Water-holding capacity of non-frozen of stools
- Self-report of amount of supplement consumed
