<![CDATA[Hypertensive disorders in pregnancy can affect pregnancy and birth outcomes. One non-pharmacological intervention is probiotic milk, which may be beneficial for hypertension in pregnancy. The purpose of this study was to determine the effectiveness of probiotic administration on blood pressure in pregnant women with hypertension. This study uses a quasi-experimental design (pretest-posttest with a control group). In this design, there are two groups: the intervention group (n = 30) and the control group (n = 30). This study uses simple random sampling. Data collection was conducted at health service facilities, namely health centres in the Kediri city area. Data collection began from March to July 2024. Probiotic milk supplementation of 125 ml was administered once daily for 63 days, while the control group received standard care. The results of the study using the t-test obtained the average post-test blood pressure in the intervention group, namely m = 124.07 mmHg, SD = 5.521 and the average diastolic pressure m = 75.60 mmHg, SD = 7.356. The average post-test systolic pressure in the control group was m = 141.83 mmHg, SD = 7.091, and the average diastolic pressure was m = 87.67 mmHg, SD = 9.132, with a p-value = 0.000. This shows that blood pressure (systolic and diastolic) in the intervention group was lower than in the control group. Probiotic milk supplementation given to pregnant women with hypertension has a greater potential to reduce blood pressure compared to the control group. Health workers need to be able to recommend probiotic consumption to pregnant women with hypertension. Further research should consider improved study designs and long-term monitoring of probiotic milk supplementation with a larger number of participants.]]>
