Lifestyle interventions for hypertension management in primary care: a narrative review.

Abstract

Hypertension is one of the leading chronic diseases globally and a major contributor to cardiovascular morbidity and mortality. Despite advances in pharmacological therapy, medication alone remains limited in achieving optimal control. This review synthesizes recent hypertension management guidelines, including those from the European Society of Cardiology (ESC, 2024), American Heart Association/American College of Cardiology (AHA/ACC, 2025), Taiwan Society of Cardiology/Hypertension Society (2022), and Korean Society of Hypertension (KSH, 2018). All guidelines consistently emphasize sodium restriction, weight reduction, regular exercise, moderation of alcohol intake, smoking cessation, and adoption of healthy dietary patterns such as the Dietary Approaches to Stop Hypertension, Mediterranean, or culturally adapted diets. The ESC 2024 guideline elevates lifestyle modification to Class I, Level A, specifying targets for sodium (<2 g/day) and potassium (≥3.5 g/day). The AHA/ACC 2025 guideline provides quantitative estimates, reporting approximately 1/1 mm Hg blood pressure reduction per kilogram of weight loss, and incorporates newer strategies such as glucagon-like peptide-1 receptor agonists and bariatric surgery when lifestyle measures alone are insufficient. Taiwan's 2022 guideline frames recommendations under the S-ABCDE (sodium restriction, alcohol limitation, body weight reduction, cigarette cessation, diet adaptation, exercise adoption) mnemonic and uniquely includes genetic factors such as ALDH2 polymorphisms. The KSH 2018 guideline emphasizes salt restriction (<6 g/day), maintaining a body mass index <25 kg/m2, and adherence to traditional Korean diets. Lifestyle modification remains the cornerstone of hypertension prevention and management, particularly in primary care. Future directions should focus on integrating these approaches with pharmacotherapy, digital health strategies, and personalized prescriptions.
