Among 16 Montserratian adults with hypertension, adherence to the DASH diet was constrained by financial, logistical, cultural, and knowledge barriers despite motivation to improve diets.
What are the barriers and facilitators to following the DASH diet in adults with hypertension in Montserrat?
DASH diet adherence in Montserrat is constrained by financial, logistical, cultural, and knowledge barriers, highlighting the need for culturally appropriate structural supports.
Introduction Hypertension is the leading modifiable risk factor for cardiovascular disease, with high prevalence in the Eastern Caribbean. Dietary modification is central to prevention and management, with the Dietary Approaches to Stop Hypertension (DASH) diet supported by strong clinical evidence. DASH promotes increased consumption of fruits, vegetables, whole grains, nuts, seeds and pulses while limiting salt, sugar, high-fat meats and dairy, and refined carbohydrates. Although promoted in primary care in Montserrat, adherence may be limited by structural, social and cultural barriers. We aimed to explore the barriers and facilitators experienced by Montserratians attempting to follow the DASH eating plan. Methods We conducted semi-structured interviews with 16 adults in Montserrat diagnosed with hypertension recruited through primary healthcare providers. Purposive sampling ensured representation across sex and country of birth. Interviews lasting 20–40 min were conducted between June and August 2025, audio-recorded, transcribed verbatim and anonymised. Using a topic guide developed with local and UK experts, participants discussed dietary practices, barriers, facilitators and suggested interventions. Data were analysed using the Theoretical Domains Framework (TDF) through deductive thematic analysis. Results Participants (aged 40–79) identified five themes shaping DASH adherence: understanding of hypertension and DASH, access to healthy foods, skills and self-efficacy, cultural practices and readiness to change. While hypertension was seen as urgent, cost, availability and seasonality of fruits, vegetables and fish limited adherence. Cooking and cultivation skills supported adherence, though food label literacy was low. Cultural practices and family dynamics both enabled and constrained adherence, and taste preferences often posed barriers. Suggested interventions included nutrition education, financial support, agricultural coordination and peer support. Conclusions Montserratian adults with hypertension are motivated to improve their diets, but DASH adherence is constrained by financial, logistical, cultural and knowledge barriers. Effective interventions must integrate structural supports with culturally appropriate strategies, developed collaboratively with stakeholders, to ensure feasibility, acceptability and sustainability.
