Factors influencing compliance with multiple injection immunization among mothers of toddlers at The Public Health Center Porong Integrated Health Service Post, Sidoarjo, East Java, Indonesia: A Descriptive Study

Introduction: Immunization significantly reduces infant and child morbidity and mortality rates globally. However, basic immunization coverage in 65 countries must catch up to the 90% global target. Multiple injection immunization involves administering multiple immunizations in one visit, enhancing early protection during vulnerable periods. This approach reduces the need for multiple health visits, which is particularly beneficial for children facing access barriers. It also improves healthcare efficiency, minimizes missed opportunities, and lessens the burden on parents needing frequent facility visits. Objective: The objective of this study was to explore the factors influencing compliance with multiple injection immunization among mothers of toddlers at the Public Health Center Porong Integrated Health Service Post, Sidoarjo, East Java, Indonesia Method: Conducted in March 2024 at Public Health Centre Porong, Indonesia, this study employed a consecutive sampling method. It involved 100 mothers with infants aged 13 to 24 months who had received immunizations at the Post. Data were collected through structured interviews and analyzed to determine compliance rates and associated factors. Result: Among the participants, 91% of mothers were aged between 20 to 35 years, indicating a productive age group. The compliance rate for multiple injection immunization was 61%. Additionally, 74% of mothers had completed high school, suggesting a positive association between higher education and enhanced health decision-making capabilities. A significant proportion of mothers (75%) were not employed, highlighting the influence of occupation on health-related knowledge and practices. Conclusion: The study underscores the necessity for targeted health education initiatives tailored to the diverse demographic and occupational characteristics of mothers. Such interventions should improve maternal knowledge and promote adherence to essential childhood immunizations, leveraging the cognitive advantages associated with higher education and non-working status. This approach aims to foster informed decision-making and proactive health behaviours among mothers in community health settings.
