Prevalence and associated factors of uncontrolled hypertension among hypertensive patients: a nation-wide survey in Thailand

Abstract

Objectives The objectives of the research were to determine the prevalence and factors associated of uncontrolled blood pressure among Thai hypertensive patients in a nationwide survey. Results A total of 65,667 patients with hypertension were included in this study. The greater proportion of participants, 40,834 (62.2%), were females. The average age of participants was 63.9 ± 11.1 years. Uncontrolled hypertension was detected among 16,122 patients (24.6%; 95% CI 24.2–24.9). Among males and females, uncontrolled hypertension was 25.6% (95% CI 25.1–26.2) and 23.9% (95% CI 23.5–24.3) respectively. Multivariate analysis showed that the uncontrolled hypertension was significantly associated with being male, age, regions, hospital levels, diabetes comorbidity, higher body mass index, low density lipoprotein cholesterol level and the number of antihypertensive medications.

Characterizing Patients with Uncontrolled Blood Pressure at an Urban Hospital in Hanoi, Vietnam

“…The rate of uncontrolled hypertension among hypertensive patients in our study (40.5%) could be comparable to the previous study performed in ten provinces of Vietnam (37.7%) [ 14 ]. This finding was lower compared to other countries in Asia and Africa such as China (62.5%), Japan (62.9%) [ 2 , 5 ], India (63.6%) [ 16 ], South Africa (75.5%) [ 17 ], Democratic Republic of the Congo (77.5%) [ 18 ], Ghana (57.7%) [ 19 ], and Ethiopia (52.5%) [ 20 ], but higher than that in Thailand (24.6%) [ 1 ], the USA (31.1%), and the UK (39.2%) [ 2 ]. The differences in demographic and clinical characteristics of hypertensive patients across studies regarding gender, medication adherence, body mass index, comorbidity, and behaviors (e.g., alcohol use or smoking) might be the reasons for the diversity of uncontrolled hypertension prevalence.…”

“…High blood pressure, or hypertension, has been well recorded as a leading cause of morbidity and mortality in both developed and developing nations. People with hypertension are particularly vulnerable to cardiovascular diseases (CVDs), stroke, or renal failures [ 1 ]. It is estimated that the global prevalence of hypertension in adults is 30.8% [ 2 ].…”

“…It is estimated that the global prevalence of hypertension in adults is 30.8% [ 2 ]. Great efforts to advance the diagnosis and treatment of hypertension for controlling hypertension have been made; however, the rates of uncontrolled blood pressure are still high [ 1 , 3 , 4 ], especially in Asian countries. Prior literature in China and Japan indicated that among hypertensive patients receiving treatment, uncontrolled hypertension was observed in 62.5% and 62.9% of hypertensive patients, respectively [ 2 , 5 ], while these rates in the United States (US) and the United Kingdom (UK) were 31.1% and 39.2%, correspondingly [ 2 ].…”

<p>Effectiveness of a Multidisciplinary Approach Intervention to Improve Blood Pressure Control Among Elderly Hypertensive Patients in Rural Thailand: A Quasi-Experimental Study</p>

“…Crowded clinics and long waiting times for treatment at the health facility have also been reported among the causes. [12][13][14] Moreover, patients might not adhere to regular schedules for medication, or may have difficulty in taking various drugs. In addition, the insufficient attention from health-care providers to provide adequate information to patients has been cited as another challenge, as well as a lack of attention to make the necessary adjustments to medication when patients fail to effectively control their blood pressure.…”

“…In addition, the insufficient attention from health-care providers to provide adequate information to patients has been cited as another challenge, as well as a lack of attention to make the necessary adjustments to medication when patients fail to effectively control their blood pressure. 13,14 Successful strategies to improve blood pressure control among hypertensive patients involve multiple interventions. Many studies recommend various complex interventions that appear to be more effective than any single intervention.…”
