potentially modifiable parental behaviors and beliefs associated with these outcomes.
METHODS. We conducted telephone interviews with parents of 2-to 12-year-old children
with persistent asthma, in a Medicaid plan and a large provider group. Suboptimal control
was defined as≥ 4 symptom days,≥ 1 symptom night, or≥ 4 albuterol use days in the …

PURPOSE OF THE STUDY. There were 2 objectives for the study,(1) to define the rates of

characterize how parental behaviors relate to these patterns. STUDY POPULATION. The
study included 754 children 2 to 13 years of age with persistent asthma in a Medicaid plan
and a large provider group. METHODS. Telephone interviews were conducted with parents
of participants to determine rates of suboptimal control and controller underuse. Suboptimal …
