ABSTRAK Hipertensi merupakan penyakit kronik tidak menular bersifat Ausilent killerAy tidak menunjukkan gejala yang jelas yang dapat menyebabkan komplikasi serius jika tidak di Penelitian ini bertujuan untuk mengidentifikasi dan memetakan hambatan yang mempengaruhi kepatuhan pasien terhadap terapi hipertensi, baik pengobatan farmakologis maupun perubahan gaya hidup, serta mengeksplorasi faktor sosial, psikologis, ekonomi, budaya, dan sistem kesehatan yang berkontribusi terhadap rendahnya kepatuhan pasien. Penelitian ini menerapkan metode cakupan berdasarkan kerangka kerja yang ditulis oleh Arksey dan O'Malley. Artikel dicari melalui data dasar Science Direct. Scopus, dan ProQuest dengan menggunakan kata kunci ("Antihipertensi" ATAU "Hipertensi") DAN ("Hambatan") DAN ("Orang Dewasa") DAN ("Terapi" ATAU "Perawatan") DAN ("Modifikasi gaya hidup"), meliputi publikasi tahun 2020 sampai dengan 2025, berbahasa Inggris dan teks lengkap. Setelah melalui tahap seleksi, diperoleh 21 artikel yang memenuhi kriteria inklusi untuk dianalisis lebih lanjut. Analisis ini menunjukkan ada berbagai hambatan kepatuhan terapi yaitu faktor pasien, terapi, kondisi medis, sosial ekonomi dan sistem kesehatan. Faktor pasien kurangnya pengetahuan, literasi kesehatan rendah, dan motivasi rendah. Faktor terapi meliputi efek samping obat dan ketersediaan obat tidak konsisten. Faktor kondisi medis yaitu komorbiditas, hipertensi asimtomatik. Faktor sosial ekonomi yaitu pendapatan rendah dan pendidikan rendah. Faktor sistem kesehatan meliputi komunikasi rendah dan perawatan primer terbatas. Hambatan tersebut bersifat kompleks dan saling terkait. Meningkatkan kepatuhan membutuhkan pendekatan holistik yang mempertimbangkan aspek individu, sosial, budaya dan sistem kesehatan.

Desember 2025 e-ISSN: 2338-3445 p-ISSN: 0853-9987 Socioeconomic factors included low income and low education. Health system factors included poor communication and limited primary care. These barriers are complex and Improving adherence requires a holistic approach that considers individual, social, cultural, and health system aspects. Keywords: barriers to compliance, hypertension, scoping review, treatment INTRODUCTION Hypertension is one of the biggest global health problems, with a prevalence of more than 1 billion people worldwide . This condition is a major cause of cardiovascular disease, including stroke and heart disease, and contributes to approximately 9. 4 million deaths each year . The WHO reports that only one in five people with hypertension successfully controls their blood pressure . The high prevalence and low control rate have led to hypertension being dubbed the Ausilent killerAy because it often goes undetected until complications arise . Risk factors for hypertension are divided into unmodifiable factors, such as age, gender, and genetics, and modifiable factors such as obesity, salt intake, high-fat diet, smoking, alcohol, stress, and lack of physical activity. Prevention efforts through healthy lifestyle changes and early detection are key strategies in reducing the global burden of hypertension . Pathophysiologically, hypertension is divided into primary hypertension . Ae95% of case. , which is influenced by genetic and lifestyle interactions, and secondary hypertension . Ae10% of case. due to kidney disease, hormonal disorders, or the use of certain medications. Blood pressure increases due to peripheral resistance, sodium retention, and hormonal dysregulation that disrupts blood vessel elasticity. Adherence to therapy plays an important role in keeping blood pressure under control and preventing further complications . However, many patients remain noncompliant with treatment and lifestyle changes due to limited knowledge, perceptions of vulnerability, disease severity, and self-efficacy . Therefore, further research on risk factors, pathophysiological mechanisms, and treatment adherence is essential as a basis for hypertension control interventions. , . In addition to the factors mentioned above, psychosocial and cultural factors also play a significant role. Studies show that stress, anxiety, depression, and social stigma associated with long-term medication use can reduce patient adherence. Reliance on traditional or herbal remedies, which are cheaper and more reliable in some communities, is also a reason for patients to discontinue prescribed antihypertensive medication . This study shows that adherence is influenced by complex factors such as personal beliefs, risk perception, self-efficacy, social stigma, family support, financial constraints, and access to healthcare, which vary across local contexts, including reliance on traditional medicine and high-salt dietary habits. Although many studies have examined patient adherence to hypertension therapy, most focus only on partial aspects such as individual behavior or drug-related side effects. There is still a lack of comprehensive studies that map barriers to adherence across multiple dimensions Ai including patient, therapeutic, medical, socioeconomic, cultural, and health system This gap highlights the need for a scoping review that synthesizes findings from various studies to provide an integrated perspective. By identifying these multidimensional barriers, this review aims to generate evidence that can serve as a basis for holistic interventions to improve therapy adherence and reduce hypertension Therefore, this study aims to identify barriers to adherence in hypertension patients, both related to medication and lifestyle changes, as well as the social, psychological, economic, cultural, and healthcare system factors that influence https://doi. org/10. 34011/jmp2k. e-ISSN: 2338-3445 p-ISSN: 0853-9987 MEDIA PENELITIAN DAN PENGEMBANGAN KESEHATAN Vol 35 No 4.

Identification of Relevant Studies and Study Selection Through a literature search in several databases such as Science Direct. Scopus, and Proquest.

Articles published between 2020 and 2025 and in English. https://doi. org/10. 34011/jmp2k. e-ISSN: 2338-3445 p-ISSN: 0853-9987 MEDIA PENELITIAN DAN PENGEMBANGAN KESEHATAN Vol 35 No 4. Desember 2025 Minimum 6 months old. Selected articles were in English, available in full text, and open access . The study selection process used the Rayyan application to screen articles. Articles were uploaded to Rayyan and screened based on predetermined inclusion and exclusion criteria, such as discussing barriers to adherence to hypertension therapy in adults, being relevant, being in English, and being published in the last five years. Duplicate articles were removed, and then title and abstract screening were performed. Articles that did not address barriers to adherence, were published within the last five years, involved individuals under 40 years of age, were not open access, or were not in English were Articles that met the criteria proceeded to full-text screening. Data extraction The data extraction process was performed periodically using Microsoft Excel. The extraction table included information such as the identity of the study author, year, country, objective, study design, location, population, and factors associated with barriers to adherence to hypertension therapy .

This scoping review excels in comprehensively mapping barriers to adherence to hypertension therapy from individual, social, economic, cultural, and health system perspectives. The methodology follows the Arksey and O'Malley framework, with literature sources from reputable databases and diverse study contexts. However, its limitation is that it only includes English-language articles from 2020Ae2025 without an in-depth methodological quality Consequently, the results of this review are crucial for designing evidence- https://doi. org/10. 34011/jmp2k.

CONCLUSION The review results indicate that adherence in hypertensive patients is influenced by various multidimensional barriers. Individual factors such as understanding, health literacy, motivation, therapy fatigue, comorbidities, and physical or cognitive limitations are key challenges. Therapeutic factors include medication side effects, regimen complexity, inconsistent medication availability, and the use of traditional medicine. Other barriers include medical conditions, socioeconomic factors such as income, access to healthcare, education, transportation, and employment, and health system factors such as ineffective communication, limited ongoing education, and low-quality primary care. Therefore, a comprehensive approach is needed through effective education, increased health literacy, improved services and communication, and socioeconomic support to improve patient adherence and quality of life and prevent ACKNOWLEDGEMENT The authors would like to thank all those who assisted in the preparation of this review, particularly the review team for their valuable input, and the institutions and universities that supported this research.
