Relationship Between Hemoglobin A1c and Fecal Incontinence in a Nationwide Cohort Study.

Area of Science:

• Endocrinology
• Gastroenterology
• Public Health

Background:

• Diabetes mellitus is associated with various gastrointestinal issues, including fecal incontinence (FI).
• Understanding the relationship between glycemic control and FI is crucial for managing diabetes complications.

Purpose of the Study:

• To investigate the association between hemoglobin A1c (HbA1c) levels and the prevalence of fecal incontinence in a large, representative sample of US adults.
• To identify specific subgroups that may be at higher risk.

Main Methods:

• Analysis of data from the National Health and Nutrition Examination Survey (2005-2010) including adults aged 20 years and older with available HbA1c and bowel health data.
• Fecal incontinence defined as any involuntary loss of stool in the past 30 days.
• Multivariable logistic regression models were used to estimate adjusted odds ratios (aORs) for FI based on HbA1c levels, controlling for relevant covariates.

Main Results:

• A total of 13,787 adults were included, with 9.3% reporting fecal incontinence.
• Elevated HbA1c levels were significantly associated with an increased odds of FI (aOR 1.09).
• This association was particularly notable in individuals with diabetes, women, those under 65, overweight/obese individuals, non-white populations, and those experiencing solid stool incontinence.

Conclusions:

• Increasing hemoglobin A1c levels are independently associated with a higher likelihood of fecal incontinence.
• These findings highlight the importance of optimizing glucose control in individuals with diabetes to mitigate the risk of FI.
• Interventions targeting glycemic management may benefit specific patient subgroups experiencing fecal incontinence.
