Background: This study aims to show ANC characteristic data and its analysis can be used as a tool to ensure a better ANC quality, especially in relation to the incidence of eclampsia. Method: Retrospective descriptive study using medical records of referred pregnant women at >20 weeks of gestation and postpartum women >12 weeks diagnosed with eclampsia at Dr. Soetomo General Hospital, Surabaya in 2015-2019. Result: p-value of 0.077 was obtained for the relationship between the number of ANC visits and the incidence of eclampsia with OR (95% CI) 1.673 (943-2.970), Then, from T1 to T10, the quality of ANC with the incidence of eclampsia was obtained T1: p-value 0,660 OR (95% CI) 1.205 (524-2.772) T2: p-value 0,051 OR (95% CI) 2.221 (997-4.947),T3: p-value 0,724 OR OR (95% CI) 914 (554-1.507),T4: p-value 0,731 OR (95% CI) 1.138 (545-2.376), T5: p-value 0,191 OR (95% CI) 1.714 (759-3.874), T6: p-value 0,459 OR (95% CI) 1.234 (707-2.154),T7: p-value 0,454 OR (95% CI) 1.933 (472-7.912),T8: p-value 0,627 OR (95% CI) 1.138 (676-1.914), T9: p-value 0,784 OR (95% CI) 1.138 (650-1.768),T10: p-value 0,525 OR (95% CI) 916 (542-1.551). Conclusion: No significant relationship between the number and quality of ANC and the incidence of eclampsia, both classic and crucial types.
