Cardiovascular Journal of Africa • SAHS Biennial Congress 2024 33 AFRICA Submission ID: 1643 Introduction Despite the known benefits of physical activity and diet modifications for hypertension control, adults in rural South African settings still have high levels of uncontrolled hypertension. Most physical activity and diet interventions for hypertension control of rural adults require financial commitment and are not tailored to suit their contextual needs. This study outlines an intervention which targets adjusting routine physical activity and diet practices for the control of hypertension in adults from rural South Africa (HYPHEN).The aim of this study was to evaluate the feasibility and acceptability of HYPHEN for adults aged 40 years and older living with hypertension in rural north-east South Africa. Methods A one-arm 10-weeks intervention was conducted. Feasibility was measured via assessing recruitment and retention rates. Acceptability was assessed through interviews after the 10 weeks intervention using pre-determined themes of perceived expectations, benefits, motivation, and barriers concerning the intervention. Fidelity was evaluated by intervention adherence, dosage, quality, and participant responsiveness. Results Data collected to measure outcomes was complete. Our study demonstrated high level of feasibility, acceptability, and fidelity. Thirty (100% of target) participants were successfully recruited over two days, 28 (93%) participants were retained, and 28 (93%) provided complete data. Qualitative data demonstrated high acceptability. All four measures of fidelity demonstrated that the intervention was delivered as planned. The study demonstrated a promise of success with a modest reduction in systolic blood pressure. Conclusion This was, to the authors’ knowledge, the first study in rural South Africa to determine whether adaptations in physical activity and diet based on existing daily routine would be feasible and acceptable by adults for the control of hypertension. Although deemed feasible and acceptable, some amendments are required to the intervention procedures that were carried out before a full trial can be rolled out.
