RESUMO

OBJECTIVE: Evaluate the immunization coverage at 12 and 24 months of life, in Curitiba and their health districts, as well as to analyse the influence of child and maternal individual and contextual factors, particulary those related to public health services and their influence on vaccination status. METHODOLOGY: A cross sectional study was led with children that are resident in Curitiba, born in 2002. The data sources were: i) the liveborn information system (SINASC); ii) the municipal electronic medical record; iii) home interviewing for cases with incomplete records. It was used the software RECLINK II to make the databases linkage. It was performed bivariate analysis and multilevel logistic regression analysis (MLwiN 2.0 software) to investigate factors associated to interest outcomes. RESULTS: For a final sample of 2637 children the immunization coverage in Curitiba was 95.3 per cent at 12 months and 90.3 per cent at 24 months, with a low variation between the sanitary districts; The adequacy evaluation of the doses shows 0.2 per cent to 0.9 per cent of vaccine applied in dates or ranges lower than the recommended and 2.8 per cent to 32.2 per cent later than the recommended. Most children (98.8 per cent ) have municipal electronic medical record, 97.7 per cent have at least one dose of vaccine applied in the municipal health computerized network, 73.3 per cent had medical consultation in these health units, and children with three or more consultations in basic units / ESF have better vaccine status. Among children monitored by health units, has been estimated in 4 per cent and 7.3 per cent the missed opportunities for immunization. The multivariate analysis shows, independently associated to the incomplete vaccine status at 12 months: teenager mother (OR= 2.8); birth order (OR= 7.3 for 2nd and 3rd child and OR=22.2 after the 4th child) already considering interactions with other variables; inadequate number of prenatal consultation (OR=2.6); the number of medical consultations in basic units / ESF lower than 3 per year (OR=2.2). For the incomplete vaccine status at 24 months arises as independently associated: the birth order (OR=2.5 for the 2nd and 3rd child; OR=5.3 after the 4th child); inadequate number of prenatal consultation (OR=1,8); the number of medical consultations in basic health units / ESF lower than 3 per year (OR=1.5) and have temporary register or none register when compared with definitive register (OR=1.7) and inversely associated to mothers aged 35 years and more (OR=0,6). Although the bivariate analysis point better vaccination status among children linked to a health unit where the Family Health Strategy is completely adopted and in health districts of worst socioeconomic stratum, multivariate analysis revealed no association. CONCLUSIONS: The study results shows the relevance of public policies in promoting health equity and identify associated factors that must be considered in the improvement of immunization programs
