Barriers and Facilitators to Dietary Salt Reduction Among Patients With Hypertension in Southern Nigeria: A Hospital-based Qualitative Study.

Introduction: Reduction in salt intake improves blood pressure control and reduces the risk of hypertension and other noncommunicable diseases (NCDs). However, salt intake remains high among Nigerians. This study aimed to identify barriers and facilitators to salt reduction among hypertensive patients attending a family medicine clinic in southern Nigeria.

Methodology: A focussed group discussion (FGD) exploring patients' perceptions of the barriers and facilitators to salt reduction was conducted with 8 groups of purposefully selected 74 hypertensives who consumed excess dietary salt, stratified by age and sex, using an FGD guide. Thematic analysis was then performed using Nvivo^® version 12 pro. Ethical approval was obtained from Irrua Specialist Teaching Hospital (ISTH), and written informed consent was obtained from the patients before the FGD.

Results: Respondents had a mean age of 51.96 ± 8.98 years. The majority were females (47, 63.5%) and had uncontrolled blood pressure (66, 89.2%). Five major themes were identified, from which several minor themes emerged. Respondents rated their overall health as good but expressed concerns about their poor blood pressure control. Identified barriers to salt reduction included family pressure, ignorance, ready availability and affordability of salt and lack of affordable alternatives. Facilitators of salt reduction were measuring the amount of cooking salt, removing salt from the dining table and providing substitutes. Respondents, however, expressed willingness to reduce their salt consumption.

Conclusion: The study identified barriers and facilitators to salt reduction. There is a need to create awareness of the safe amount of salt to be consumed and provide safe and readily available alternatives.
