<![CDATA[The World Health Organization (WHO) reports that acute respiratory infections (ARI), especially pneumonia, remains the leading cause of death in children under five. In Indonesia, ARI remains the leading cause of infant visits to health care facilities. Prevention of ARI can be achieved through complete basic immunizations and the implementation of non-pharmacological interventions such as infant massage, which plays a role in boosting children's immune systems. This study aims to determine the relationship between complete immunizations and infant massage and the prevention of ARI among toddlers in the Sawah Lebar Community Health Center work area in 2025. This study used quantitative methods with a cross-sectional design. The population was all toddlers aged 12–59 months in the Sawah Lebar Community Health Center work area, totaling 660 toddlers. A sample of 87 respondents was drawn using a purposive sampling technique. Data analysis was performed using univariate and bivariate methods using the Chi-Square test with a 95% confidence level. The results of the study showed a significant relationship between complete immunization and the prevention of ARI in toddlers (p = 0.004 (p < 0.05), and there was a significant relationship between infant massage and the prevention of ARI in toddlers (p = 0.007 (p < 0.05). It was concluded that complete immunization and infant massage are significantly associated with the prevention of ARI in toddlers. Therefore, it is hoped that health workers can increase public education regarding the importance of complete basic immunization and infant massage as promotive and preventive efforts to reduce the incidence of ARI in toddlers.]]>
