OBJECTIVES: To gather data concerning bowel habits and toilet training of developmentally normal children ages 5 to 8 years. METHODS: A questionnaire containing information on age, race, and sex was completed anonymously by a parent in 9 pediatric practices. Recall information was elicited about onset and completion of toilet training, frequency and quality of stooling, size of bowel movements, and behavioral components of defecation. RESULTS: Questionnaires were completed for 1142 children. When all of the children were considered together, toilet training started at a mean of 27.2 months and was completed at a mean of 32.5 months. It began and was completed nearly 3 months earlier for girls than for boys (P<0.001). African American children started and completed toilet training at least 6 months earlier than white children (P<0.001). Of the children, 95% defecated either daily or every other day. Straining at defecation and infrequent stooling were reported significantly more often for girls, whereas staining of underclothes and passage of large bowel movements were reported more often in boys. Approximately 10% of children fulfilled criteria for functional constipation. CONCLUSIONS: Most of the children between 5 and 8 years of age have a medium-size bowel movement daily or every other day without straining or withholding. Although African American children toilet train at an earlier age than do white children, bowel habits appear to be similar. A sizeable subgroup of children presenting to primary care providers have a history that is consistent with constipation.
