Perceptions of diarrhea vary widely. Many people experiencing diarrhea symptoms do not self-report diarrhea, indicating the term is unreliable for studies.

Area of Science:

  • Gastroenterology
  • Epidemiology
  • Public Health

Background:

  • Diarrhea is a common health concern with significant public health implications.
  • Understanding the general population's perception of diarrhea is crucial for accurate epidemiological studies and clinical trials.

Purpose of the Study:

  • To investigate how the general population perceives and defines diarrhea.
  • To assess the consistency between self-reported diarrhea and the presence of specific diarrheal symptoms.

Main Methods:

  • An age- and gender-stratified random sample of 1644 residents from Olmsted County, Minnesota, aged 20-64 years was surveyed.
  • A valid self-report questionnaire was mailed to subjects, achieving a 77% response rate.

Main Results:

  • Only 3.5% reported usual bowel pattern as diarrhea alone, and 9.0% reported alternating diarrhea and constipation.
  • Loose/watery stools and urgency were common in self-reported diarrhea; incomplete evacuation was common in alternating bowel habits.
  • Diarrheal symptoms poorly discriminated self-reported diarrhea, and only 39% with key symptoms reported diarrhea.

Conclusions:

  • There is a significant lack of agreement between self-reported diarrhea and the presence of typical symptoms.
  • The term "diarrhea" should be used cautiously in epidemiological studies and clinical trials due to its ambiguity.
  • Current definitions may not accurately capture the symptom experience of diarrhea in the general population.
