To determine the most frequently diagnosed conditions among rural and non-rural children age 5 to 9 and assess for environmental influences, data from the National Ambulatory Medical Care Survey (1996-2001) were used to examine frequencies of diagnoses in children age 5 to 9. Separately, we examined rural and non-rural outpatient physician visits in weighted multivariate logistic regression models. Overall, the most frequent diagnosis was routine health check, followed by several acute conditions. When analyzed separately, non-rural children were significantly more likely to visit a physician for routine health check (P = 0.002), asthma (P = 0.005), and acute upper respiratory infection (P = 0.037). Rural counterparts were significantly more likely to be seen for attention deficit disorder (P = 0.000), otitis media (P = 0.017), chronic rhinitis (P = 0.017) and influenza (P = 0.037). Children age 5 to 9 are healthy overall. When illness occurs, it is usually acute. Rural and non-rural, young, school-aged children exhibit many similarities in healthcare utilization, but differences occur. Most surprising is the difference in the diagnosis frequency of attention deficit disorder.
