Prevalence of functional gastrointestinal disorders in infants and toddlers.

OBJECTIVES

To determine the prevalence of gastrointestinal symptoms suggestive of an infant/toddler functional gastrointestinal disorder (FGID) as reported by parents in a representative community sample.

STUDY DESIGN

Mothers (n = 320) of children aged 0-3 years old were recruited in the US and completed a questionnaire about their child's and their own gastrointestinal symptoms.

RESULTS

By Rome criteria, 27% of infants/toddlers qualified for FGIDs. Infant regurgitation was the most common disorder in infants and functional constipation in toddlers. No age, sex, or race differences were found in FGID diagnoses. Compared with those who did not meet Rome criteria, toddlers with FGID had lower quality of life (M = 80.1 vs M = 90.3, P < .001), increased medical visits (M = 0.38 vs 0.14; P < .05), mental health visits (M = 0.29 vs 0.06; P < .05), and hospital stays (M = 0.35 vs 0.06; P < .01). A child was more likely to suffer from hard stools if the parent also reported hard stools (P = .02), but similar association was not found with loose stools.

CONCLUSIONS

FGIDs are common in infants and toddlers and can be identified in the general population. They do not vary with sex and race. Quality of life is reduced in those with FGIDs. More research is needed into these largely neglected conditions as it may improve the lives of a significant number of young children.
