Association Between Resolution of Constipation and Reduced Incidence of Fecal Incontinence: A Population-Based...

Area of Science:

• Gerontology
• Gastroenterology
• Epidemiology

Background:

• Constipation is a common condition in older adults.
• Few studies have explored the link between constipation and subsequent fecal incontinence.
• The impact of constipation resolution on fecal incontinence incidence remains under-investigated.

Purpose of the Study:

• To investigate the association between constipation resolution and the incidence of fecal incontinence.
• To determine if resolving constipation reduces the risk of developing fecal incontinence in community-dwelling older adults.

Main Methods:

• A longitudinal study of 2233 Japanese adults aged 75 years and older without baseline fecal incontinence.
• Constipation and fecal incontinence were assessed via questionnaire at baseline and 1-year follow-up.
• Logistic regression models were used to calculate adjusted odds ratios for incident fecal incontinence.

Main Results:

• Constipation was associated with a higher incidence of fecal incontinence (aOR: 1.42).
• Participants with resolved constipation had a significantly lower incidence of fecal incontinence compared to those with sustained constipation (aOR: 0.35).
• Fecal incontinence incidence was 11.6% in the constipation group versus 6.8% in the non-constipation group.

Conclusions:

• Constipation is a risk factor for developing fecal incontinence in older adults.
• Resolution of constipation is linked to a reduced incidence of fecal incontinence.
• Effective constipation management may be a key strategy to prevent fecal incontinence in the elderly.
