Faktor-Faktor yang Mempengaruhi Kelengkapan Imunisasi Dasar Lengkap pada Bayi di Puskesmas Tanah Abang Kabupaten PALI

Abstrak

Immunization is one of the most effective public health interventions for preventing infectious diseases by inducing protective immunity through vaccination. Complete basic immunization in infants is essential to protect them from vaccine-preventable diseases that can result in severe morbidity, disability, or death. However, coverage of complete basic immunization remains suboptimal in several settings, including the service area of Tanah Abang Primary Health Care Center, Penukal Abab Lematang Ilir (PALI) Regency. This study aims to analyze the factors associated with the completeness of basic immunization in infants at Tanah Abang Public Health Center in PALI Regency in 2025, particularly in relation to mothers' knowledge, attitudes, and family support. The type of research used was quantitative with a cross-sectional design. The population of the study included all mothers with infants aged 9–18 months and the sample used total sampling technique. Data collection was conducted through a structured questionnaire, then analyzed univariately and bivariately using the Chi-Square test. The univariate analysis results showed a relationship between knowledge, attitude, and family support simultaneously with the completeness of basic immunization. Meanwhile, the bivariate results showed a partial relationship between each variable. The factor of maternal knowledge was significantly related to immunization completeness with a p-value of 0.000. The factor of maternal attitude was also proven to be related with a p-value of 0.013. In addition, family support had a significant effect with a p-value of 0.000. Based on these findings, it can be concluded that knowledge, attitude, and family support play an important role in determining the completeness of basic immunization for infants. Therefore, health workers are expected to increase educational activities, provide counseling, and actively involve families to encourage the achievement of optimal basic immunization coverage.
