Hypertension in Adults With Diabetes in Southeast Asia: A Systematic Review

Diabetes is one of the most pressing health issues in the Southeast Asian region, and hypertension has been commonly reported as a comorbidity in adults with diabetes. This systematic review aimed to synthesize evidence on the prevalence and management of hypertension in adults with diabetes in Southeast Asian countries. A literature search was conducted in Ovid MEDLINE and Embase Classic + Embase from database inception until March 15, 2024. Studies were included if (1) they were conducted in Southeast Asian countries, (2) the study populations were adults with diabetes, and (3) there was information related to hypertension or blood pressure (BP) in the study results. Of the 7486 abstracts found, 90 studies qualified for this review. Most studies reported a hypertension prevalence of 70% or higher (ranging from 29.4% to 93.4%). Despite this high prevalence, a substantial proportion of these populations did not receive adequate BP control, with most studies indicating a control rate of less than 40%. There was limited evidence on the prescription of antihypertensive therapies and medication adherence. There was a lack of studies from 4 of the 11 countries in the region. This review highlights that BP control in adults with diabetes remains a significant challenge in Southeast Asia. Given the ongoing epidemiological transition, and the increasing older population in this region who are likely to accumulate multiple chronic conditions complicating medication strategies, this review highlights the urgent need to improve BP management in those with diabetes.
