Aims and Objectives To determine the effectiveness of a community‐based health programme grounded on the PRECEDE‐PROCEED model, on the knowledge, adherence and blood pressure control of community‐dwelling adults with hypertension. Background Hypertension has consistently been a leading cause of morbidity and mortality in different countries and has continuously increased in prevalence. Albeit manageable with lifestyle modification and anti‐hypertensive medications, adequate knowledge and poor adherence to these treatment regimens are issues that have led to poor blood pressure control. Design Quasi‐experimental, one‐group pretest–post‐test design. Methods The PRECEDE‐PROCEED model was used to develop and evaluate the effectiveness of the community‐based health programme. From August to October 2017, a total of 50 community‐dwelling adults with hypertension participated in the programme which included blood pressure monitoring, targeted health educations, motivational interviews, individualised lifestyle modification plans and house‐to‐house visits. Knowledge, adherence and blood pressure were assessed at the start and at the end of the 2‐month programme. Gathered data were analysed using descriptive statistics and RM‐MANOVA. The TREND checklist was followed in reporting this study (See Appendix S1). Results After 2 months, the mean adherence, systolic blood pressure and diastolic blood pressure significantly improved, attributing more than 25% of the change. Although knowledge scores were significantly higher after the programme, it only accounted 9% of the improvement. Conclusion This study provides evidence on the effectiveness of a community‐based health programme grounded on the PRECEDE‐PROCEED model on the knowledge, adherence and blood pressure control of community‐dwelling adults with hypertension. Relevance to Clinical Practice The community‐based health programme is beneficial to community‐dwelling adults with hypertension in promoting knowledge and adherence to treatment regimen and improving BP control. This study also provides a framework for developing new or enhancing existing programmes on hypertension in the Philippines.
