<![CDATA[Introduction: Blood pressure variability (BPV) has not been sufficiently addressed in community-based interventions. In Indonesia, where family members often play an important role in health-related decision-making and self-management, a family centered approach may provide a contextually appropriate strategy for improving blood pressure control and addressing BPV in patients with hypertension. Methods: A quasi-experimental study with repeated measures was conducted among 200 hypertensive adults aged 30–65 years, living with family caregivers. Participants were allocated to the intervention and control groups based on the catchment areas of public health centers, with two public health centers designated as intervention sites and one as a control site. The 12-week intervention included nurse-led virtual coaching, educational content, and digital engagement. Analysis of variance (ANOVA) and generalized estimating equations (GEE) were used to evaluate the changes within and between groups over time. Results: The intervention group showed a significant decrease in systolic blood pressure variability (BPV) with systolic BPV decreasing from 11.4 ± 2.2 to 9.8 ± 1.9 mmHg, whereas the control group showed minimal change. Similar improvements were observed in systolic and diastolic blood pressure variability, assessed using the coefficient of variation (CV). The reduction in blood pressure variability over the 12-week follow-up was significantly greater in the intervention group than in the control group (p < 0.01). The GEE analysis further confirmed significant changes. Conclusions: Family centered remote nursing is an effective and scalable approach for reducing BPV in hypertensive populations. Further investigation is warranted to explore the underlying mechanisms.]]>
