However, because most (87%) cases were not temporally associated with vaccination, we reanalyzed these data to assess risk factors for intussusception cases unrelated to Rotashield.<\/jats:p><\/jats:sec><jats:sec><jats:title>Patients and Methods:<\/jats:title><jats:p>Case\u2010patients were infants with intussusception between November 1998 and June 1999. Controls were matched by age and hospital of birth. Sociodemographic and feeding practice data were collected through parent and provider interviews. Conditional logistic regression was used to identify risk factors for intussusception, controlling for exposure to Rotashield &lt;21 days before intussusception.<\/jats:p><\/jats:sec><jats:sec><jats:title>Results:<\/jats:title><jats:p>Four hundred twenty\u2010nine cases and 1763 controls were enrolled. Among case\u2010patients, 372 (87%) had not received Rotashield within 21 days before intussusception. After adjusting for recent Rotashield administration, factors associated with intussusception included male sex (odds ratio [OR] 1.7; 95% confidence interval [CI] 1.3\u20132.2), Hispanic (OR 2.1; 95% CI 1.4\u20133.2) or black (OR 1.8; 95% CI 1.2\u20132.7) race\/ethnicity, and Medicaid enrollment (OR 1.5; 95% CI 1.1\u20132.0). Feeding practices modified the risk of intussusception. Interaction was found between introduction of solid food (ISF) and type of formula consumption. Using breast milk as the referent group, infants with ISF for at least 5 weeks who consumed soy milk\u2013based formula had a lower risk (OR 0.26; 95% CI 0.1\u20130.7) and infants without ISF who consumed cow's\u2010milk formula had an increased risk (OR 2.33; 95% CI 1.4\u20133.9).<\/jats:p><\/jats:sec><jats:sec><jats:title>Conclusions:<\/jats:title><jats:p>Risk of intussusception among US
