Effectiveness of a community coalition for improving child vaccination rates in New York City.

We used a retrospective, matching, birth cohort design to evaluate a comprehensive, coalition-led childhood immunization program of outreach, education, and reminders in a Latino, urban community. After we controlled for Latino ethnicity and Medicaid, we found that children enrolled in the program were 53% more likely to be up-to-date (adjusted odds ratio = 1.53; 95% confidence interval = 1.33, 1.75) and to receive timely immunizations than were children in the control group (t = 3.91). The coalition-led, community-based immunization program was effective in improving on-time childhood immunization coverage.

Community-based strategies to reduce childhood immunization disparities.

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.

Community empowerment to reduce childhood immunization disparities in New York City.

This paper reports on the impact of the community-based Start Right program on childhood immunization coverage in 2 communities of color in New York City. Fully launched in 2002, Start Right operates through the major social service programs of its 23 member organizations. Immunization promotion strategies are based on the following guiding principles: community leadership; integration with community programs; parental empowerment; peer health educators; tracking and feedback; and linkage with health providers. By September 2003, 2,433 children under age 5 years (14% of that age group in the community) were enrolled in Start Right. The rates for the cohort of children enrolled in 2003 were substantially higher than for those enrolled in 2002. Among the 2003 cohort of 19- to 35-month-old children, the coverage rate was 88%, significantly more than national rates: 75% for total population, 68% for African Americans, and 73% for Hispanics. The rate for our 2003 enrollment cohort exceeded the rate for New York City (78%) but did not exceed the New York City average for Hispanics (79%). Of the 2003 enrollment cohort, the Washington Heights children had the highest rates for enrollment (89.6%), exceeding New York City rates. Parents reported a high level of satisfaction with the program.
