Objectives:
To examine the relationship between sarcopenia and fecal incontinence in patients with dysphagia.
Design:
Cross-sectional study using the Japanese sarcopenic dysphagia database.
Setting:
19 hospitals including 9 acute care hospitals, 8 rehabilitation hospitals, 2 long-term care hospitals, and 1 home visit rehabilitation center.
Participants:
460 dysphagic patients, aged 20 years and older.
Measurements:
Sarcopenia was diagnosed by the 2019 criteria of the Asian Working Group for Sarcopenia. Fecal incontinence was assessed by health care professionals at baseline according to the definition of the Japanese Practice Guidelines for Fecal Incontinence. We examined whether there was a significant difference between the rate of fecal incontinence in patients with/without sarcopenia. Age, sex, type of dwelling, Barthel index, Charlson comorbidity index (CCI), calf circumference, handgrip strength, body mass index, malnourishment, C-reactive protein level, serum albumin level, and delivery of enteral nutrition by nasogastric and/or gastrostomy tube were measured. To examine the relationship between sarcopenia and fecal incontinence, logistic regression analysis was performed with adjustments for age, sex, sarcopenia, CCI, enteral nutrition, and dwelling.
Results:
The mean age of patients was 81 ± 10 years. Of the 460 study patients, 404 (88%) patients had sarcopenia and 104 had fecal incontinence (23%). The rate of fecal incontinence was higher in the sarcopenia group than the non-sarcopenia group (25% vs. 7%, P = 0.003). Logistic regression analysis showed that sarcopenia was independently associated with fecal incontinence (odds ratio: 3.114, 95% confidence interval: 1.045, 9.282).
Conclusion:
The prevalence of fecal incontinence was 23% in patients with dysphagia. Sarcopenia was independently associated with fecal incontinence, which suggests the presence of anal sarcopenia. Defecation control should be assessed in patients with sarcopenia.
