Not assessed in manuscripts reviewed under Handbook of Procedures and Standards, Version 1 |
Notes
High rating applies to oral corticosteroid and emergency department visit outcomes. All other outcomes receive a low rating because of high attrition and failure to demonstrate baseline equivalence.
Study Participants
Participants (infants and their families) were recruited from local hospitals and clinics in the Denver, Colorado, area and assigned randomly to either the intervention or the comparison group. Initially 181 infants were randomly assigned, 90 to the treatment group and 91 to the comparison group. At the four-year-old follow-up that is the focus of the paper, 72 children remained in the intervention group and 77 in the control group. This follow-up sample included European Americans (21 percent treatment, 21 percent control), African American (22 percent treatment, 25 percent control), U.S.-born Hispanic (35 percent treatment, 29 percent control) and foreign-born Hispanic (22 percent treatment, 22 percent control). Approximately half of each group had incomes less than $12,000 per year.
Setting
The study was conducted in Denver, Colorado.
Home Visiting Services
The intervention included home visits conducted by specially trained nurses. The intervention began when infants were from 9 to 24 months old and continued for 12 months. Participants received approximately 15 visits (or telephone calls) by a public health nurse. Each visit lasted an average of 53 minutes.

Comparison Conditions
Comparison group members received an educational video at the baseline interview that described risk factors for developing asthma and actions that caregivers can take to mediate the risks.
Subgroups examined
• Asthma symptom severity at baseline (low severity or high severity)
