Abstract : Recent reports suggest certain behaviors among children with autism spectrum disorders (ASD) may indicate underlying gastro-intestinal (GI) problems, and that the presence of these behaviors may help alert primary care providers to the need to evaluate a child with ASD for GI problems. The purpose of this population-based study of 487 children with ASD, including 35 (7.2%) with a medically documented history of GI problems, was to compare behavioral features of children with and without a history of GI problems. Unusual sleeping or eating habits and oppositional behavior were significantly associated with GI problems. These behaviors, however, were frequent in both children with and without GI problems, suggesting they may have limited utility in a screening capacity for GI problems.

Conclusion: Certain behaviors, including abnormalities in sleep patterns, abnormalities in mood or affect, and argumentative, oppositional, defiant or destructive behavior were described significantly more often in children with ASD who also had GI problems than in those with ASD and no history of GI problems. These features (often described as characteristics of autism) may be more common among children with autism who also have GI problems. However, because these behaviors are also frequent in children with ASD and no GI problems (nearly all children had 1 or more behaviors), they are unlikely to efficiently predict GI problems in children with ASD. Consideration of medical, biological, or physiological co-occurring conditions, genetic susceptibility, diet and nutrition, and medication use are necessary to determine whether in children with ASD both behavioral presentation and GI problems might be associated with other underlying factors.
