Tetanus Toxoid (TT) immunization is one of the important efforts in the prevention of tetanus in mothers and newborns. However, the coverage of TT immunization for brides-to-be in the work area of the Jambi Kecil Health Center in 2024 will only reach 41.9%, far below the national target of ≥80%. This study aims to analyze factors related to TT immunization coverage in brides-to-be in Muaro Jambi Regency. The research design uses an observational quantitative analytical approach with a cross-sectional method. The research population amounted to 221 brides-to-be, with a sample of 107 respondents selected through purposive sampling techniques. Data were collected using a structured questionnaire and analyzed by Chi-Square test at a significance level of α = 0.05. The strength of the relationship was measured using the Prevalence Ratio (PR) with a Confidence Interval (CI) of 95%. The results showed that knowledge (p = 0.023; PR = 0.77; 95% CI: 0.62–0.94), sources of information (p = 0.033; PR = 0.78; CI 95%: 0.63–0.98), and the role of health workers (p = 0.014; PR = 0.75; CI 95%: 0.60–0.95) were significantly related to TT immunization coverage. Meanwhile, attitudes, partner support, and access to health services did not show a significant relationship. These findings confirm the importance of increasing knowledge, optimizing information sources, and strengthening the role of health workers in increasing TT immunization coverage in the community.
