| Shone et al., 200984 Cross-sectional N = 499 Fair | Parents of children with persistent asthma in Rochester New York School District REALM Low: 33% Adequate: 67% | Child health insurance Parent's employment, ethnicity, and race | Asthma is not under good control Low: 76% Adequate: 82% Child's health is fair/poor Low: 39% Adequate: 17% | No difference between groups in rate of asthma not under good control (unadjusted): P = 0.094 Parents' in low group more likely to have child with fair/poor health (adjusted): OR, 3.96; 95% CI, 2.4-6.4 |
| DeWalt et al., 200780 Cross-sectional N = 150 Fair | Parents of children with asthma receiving care at 3 clinics in North Carolina REALM Lower: 24% Higher: 76% | None | Albuterol Use (mean days per week) Lower: 2.7 Higher: 1.5 Albuterol Use (total mean use per week) Lower: 6 doses Higher: 3 doses Appropriate Controller Use Lower: 68% Higher: 82% | Greater Albuterol use in children of parents in lower compared to higher health literacy group (unadjusted): P = 0.01 Greater total weekly Albuterol use in children of parents in lower compared to higher health literacy group (unadjusted): P = 0.03 No difference between groups in appropriate controller use (unadjusted): P = 0.15 |
