An approach of predisposing factor to increase immunization coverage

Background: Immunization for infants is a national program that should be given to all infants under 1 year of age. However in the last 3 years, coverage of basic infant immunization in Lumajang District still has not reached the target or below than 91.5%. This could be a potential outbreak of the vaccine preventable disease such as diphtheria and measles. Parents as a determinant of health decisions for children are the main actors to be approached by health workers. Purpose: This study aims to identify predisposing factors that affect mother’s health behavior about immunization and the correlation with completeness of basic immunization. Method: This is observational analytic study with cross sectional design. The sample was taken by proportionate stratified random sampling method with the sample size is 188 mothers. Predisposing factors in this study are age, number of children, education, knowledge, employment status and children parenting. Data collected using structured questionnaire. Results: There are 122 children with complete basic immunization and 66 children was incomplete. There are significant correlations between education (P Value = 0.010) and mother’s knowledge (P Value = 0.000) with completeness of basic immunization. There aren’t any correlations between mother’s age, number of children, employment and children parenting with completeness of basic immunization. Conclusion: Mother’s knowledge is predisposing factors that affect immunization behavior. To elevate achievement completeness of basic immunization, health worker must give enough information about benefit and also risk about immunization with social cultural approach in promoting immunization programs.
