Abstract
Background:
Hypertension is a leading global risk factor for cardiovascular disease and mortality. Despite the availability of effective pharmacological treatments, blood pressure control rates remain suboptimal, especially in low- and middle-income countries. Lifestyle interventions—targeting diet, physical activity, alcohol use, stress, and weight management—are increasingly recommended as first-line strategies, but their long-term effectiveness in real-world populations remains underexplored (1–3).
Aim:
To evaluate the longitudinal impact of lifestyle interventions on blood pressure control among adults with hypertension, using both secondary data from recent studies and a local observational cohort.
Methods:
This study synthesizes findings from 15 high-quality clinical trials and meta-analyses published between 2018 and 2024 assessing lifestyle-based blood pressure interventions. Additionally, a 12-month observational cohort from a regional tertiary care hospital (n = 200) and a cross-sectional community survey (n = 100) were analyzed to assess real-world adherence and outcomes. Primary outcomes included mean changes in systolic and diastolic blood pressure, and the proportion achieving target BP control (<140/90 mmHg).
Results
Across published studies, dietary approaches (e.g., DASH, sodium reduction) achieved systolic BP reductions of 4–11 mmHg and diastolic reductions of 2–6 mmHg (4–7). Physical activity interventions yielded reductions averaging 5/3 mmHg (3,5), while weight loss and stress management showed moderate but sustained benefits (2,10,11). In the hospital cohort, 67% of patients adhering to ≥3 lifestyle domains achieved BP control at 12 months, compared to 38% among non-adherents. Survey results indicated significant associations between adherence scores and BP change (p < 0.05).
Conclusion:
Lifestyle interventions are effective, scalable, and sustainable tools for hypertension control. When applied consistently, they can yield clinically meaningful improvements in blood pressure, especially when tailored to local contexts. Ongoing integration into primary care and public health strategies is essential (14,15).
