Abstract
This study demonstrates how community-based immunization promotion reduced immunization disparities. In 2002 to 2004, the coalition enrolled 3,748 children younger than 5, with 1,502 aged 19 to 35 months in April 2004. Disparity reduction was assessed by comparing coalition immunization coverage rates (4:3:1:3:3) to the National Immunization Survey 2003 rates. Logistic regression was used to assess factors contributing to up-to-date immunizations. Coverage increased from 46.0% at enrollment to 80.5%, matching nationwide rates for all (t = 0.87) or White (t = 1.99) children. The 78% for African Americans was higher than 73% for U.S. African American children (t = 2.90); 84% for Latinos was higher than 77% for U.S. Latinos (t = 2.32). Being current with age-appropriate immunizations at enrollment (OR = 9.8), being Latino (OR = 1.6), and participating through child health insurance enrollment (OR = 4.9), Women, Infants, and Children (OR = 3.1), or child care or parenting (OR = 1.9) programs increased immunization coverage. Embedding immunization promotion into existing community programs was successful in eliminating immunization disparities. Most effective programs were those with direct linkages to health care systems or that targeted young children.
