Background: Complete Basic Immunization or Imunisasi Dasar Lengkap (IDL) Program is conducted as a disease prevention effort among children, however the CBI in Indonesia does not yet achieve national target. Bangkalan Regency is one of the regencies in East Java with low immunization achievement. The study aimed to analyze determinants that influence complete basic immunization status using PRECEDE-PROCEED model.
Subjects and Method:The study was analytic observational study with cross sectional approach. The study was conducted at 10 community health centers, Bangkalan Regency, from AugustOctober 2017. A total sample of 200 mothers who have infant age 9-12 months old were selected using cluster sampling technique and purposive sampling. The dependent variable was complete basic immunization status. The independent variables were education, knowledge, occupation, attitude, distance of health care facilities, information exposure, family support, and health workers support. The data were colected using questionnaires and MCH book. The data were analyzed by path analysis. Result: Complete basic immunization status was influenced by attitude (b=0.82; 95% CI= 0.10 to 1.55; p= 0.027), health personnel support (b= 0.79; 95% CI= -0.10 to 1.67; p= 0.081), distance of healthcare facilities (b= -1.28; 95% CI= -2.13 to -0.44; p= 0.003), and information exposure (b= 1.52; 95% CI= 0.75 to 2.29; p= 0.001). Attitude was influenced by family support (b= 1.35; 95% CI= 0.71 to 2.00; p= 0.001) and knowledge (b= 2.29; 95% CI= 1.06 to 3.54; p= 0.001). Knowledge was influenced by information exposure (b= 1.54; 95% CI= 0.58 to 2.51; p= 0.002). Family support was influenced by occupation (b= 0.64; 95% CI= 0.03 to 1.26; p= 0.040). Occupation (b= 1.12; 95% CI= 0.51 to 1.75; p= 0.001) and knowledge (b= 1.27; 95% CI= 0.42 to 2.13; p= 0.003) were influenced by education. Conclusion: There is a direct and positive influence of attitude, health worker support, and information exposure toward complete basic immunization status. There is direct and negative influence of distance of healthcare facilities toward complete basic immunization status. There is indirect and positive influence of education, knowledge, occupation and family support toward complete basic immunization status.
