Among the 5,598 children studied, most were African-American (73.4%), approximately one-half were male (51%), and most mothers were in the 20 years and over age group. The designated primary care providers included public health providers (9.3%), and private providers (90.7%). Private providers included family practitioners (10.7%), pediatricians (78.3%), and other specialists. Of the 5,598 children, 2,583 (46.1%) were immunized (4:3:1 series) by 24 months of age and 1,582 (28.3%) were classified as UTD at 18 months. Of the UTD children, 351 (22.2%) were classified as AAI at 18 months. Thus 6.3% of all children were AAI. (See Table 1.)

As children grew older, increasingly smaller percentages of them received their immunizations at age appropriate intervals (Figure 1). The percentage of UTD children decreased for children beginning with 2 months of age but then rose again among children aged 15 months and older. buy cialis soft tabs

Table 2 shows that, in adjusted analysis, children who were UTD at 18 months were more likely to have been served by public as compared to private providers and that African-American children were less likely to be UTD than others. In addition, children with mothers over the age of 20 were more likely to have had their immunizations by 18 months than those with younger mothers. Among UTD children, AAI children were more likely to reside in urban areas. No other predictors were associated with AAI status among the UTD children. canadian antibiotics
