Abstract
Data from the Mexican American portion of the Hispanic Health and Nutrition Examination Survey (HHANES), conducted in 1982-83, were analyzed for the number of diphtheria, tetanus, and pertussis (DTP) immunizations reported for Mexican American children 6 months-11 years of age and for levels of tetanus antitoxin titers in Mexican American children 4-11 years of age. In Mexican American children 6 months-11 years, 98.2 per cent had one or more DTP immunizations reported (95 per cent CI: 97.5, 98.9%); 85.1 per cent had three or more DTP immunizations reported (95 per cent CI: 83.2, 87.0%). The reported immunization coverage in Mexican American children was corroborated by the tetanus antitoxin titers which were above the minimum protective level (greater than or equal to 0.01 IU/ml) in 99.6 per cent of the 4-11 year olds. Using the American Academy of Pediatrics' (AAP) recommendations for the number of DTP immunizations, 61.1 per cent of the children 6 months-11 years of age had the age-appropriate number of immunizations (95 per cent CI: 58.5, 63.7%). AAP immunization completion rates were higher for children who: had a source of care reported (62.1 vs 44.3%; 95% CI of the difference: 7.1, 28.5); had insurance coverage (63.5 vs 56.1%; 95% CI of the difference: 2, 12.8); lived in a standard metropolitan statistical area (SMSA)-not central city as compared to SMSA-central city or not SMSA (66.6 vs 57.1%; 95% CI of the difference: 4.3, 14.7); and had 12 or more completed years of education for the head of the household (65.4 vs 58.3%; 95% CI of the difference: 1.8, 12.4).(ABSTRACT TRUNCATED AT 250 WORDS)
