<![CDATA[Background : Although preeclampsia screening can be conducted through measurements of MAP and BMI, the incidence of preeclampsia at the Kanor Community Health Center remains relatively high, at 15.77%. This places the Kanor district in fifth place among the highest rates in Bojonegoro, where hypertensive disorders remain the leading cause of maternal mortality at 42.86%. This situation highlights the need for further investigation into the relationship between MAP and BMI as part of early detection efforts. Preeclampsia screening is conducted by health workers by determining the Mean Arterial Pressure (MAP) value and Body Mass Index (BMI) status. The purpose of this study is to identify the relationship between Mean Arterial Pressure (MAP) and Body Mass Index (BMI) and the incidence of preeclampsia among pregnant women in their third trimester in the service area of the Kanor Community Health Center, Bojonegoro Regency, in 2025. Method : The design used is quantitative research with a Prospective Cohort study approach. The sampling technique used Cluster Random Sampling. The population in this study were 52 third trimester pregnant women in the Kanor Community Health Center working area in March - May 2025. The instrument to collect data in this study used primary data in the form of a blood pressure measuring device (Sphygmomanometer), observation sheets and secondary data (KIA book). Result : Before conducting the correlation test, a normality test was performed using the Kolmogorov-Smirnov test, which yielded a p-value 0.000 (the data were not normally distributed). Therefore, Spearman’s Rho was used to analyze the relationship between Mean Arterial Pressure (MAP) and Body Mass Index (BMI) and the incidence of Preeclampsia. The results indicate 2 hypotheses : a significant relationship exists between MAP value and the incidence of Preeclampsia with a p-value = 0.000 (Sig. p <0.05) correlation coefficient = 0.544 and there is a relationship between BMI status and the incidence of Preeclampsia with a p-value = 0.002 (Sig. p <0.05) and correlation coefficient = 0.424. Both variables exhibited a positive correlation, meaning that the higher the MAP value (>90 mmHg) and the higher the body mass index (obesity), the greater the risk of preeclampsia in pregnant women in the third trimester. Conclusion : Based on the results of the study, pregnant women are expected to periodically check blood pressure and weight gain according to gestational age by routinely doing antenatal care at the nearest health facility.]]>
