FACTORS ASSOCIATED WITH UNCONTROLLED HYPERTENSION IN HYPERTENSIVE PATIENTS IN NON SUNG DISTRICT, NAKHON RATCHASIMA PROVINCE, THAILAND

Abstract

Hypertension is a major global public health problem, and uncontrolled blood pressure is a leading cause of cardiovascular disease, stroke, renal failure, and premature death. Despite advances in treatment, blood pressure control remains low worldwide, including in Thailand—particularly in the Non-Sung district, Nakhon Ratchasima province, where the prevalence of uncontrolled hypertension continues to rise. This study aims to identify factors associated with uncontrolled blood pressure among hypertensive patients in Non-Sung district, Nakhon Ratchasima province. A hospital-based case-control study was conducted among 354 hypertensive patients aged ≥35 years who had received continuous treatment for at least six months. Participants were equally divided into controlled (n = 177) and uncontrolled (n = 177) groups. Data were collected using structured questionnaires and health assessments. Multivariable logistic regression was applied to identify significant factors at a 95% confidence level. Significant predictors included male sex (AOR = 1.83; 95% ci: 1.09-3.09), sufficient income (AOR = 1.93; 95% ci: 1.16-3.21), hypertension duration >20 years (AOR = 1.87; 95% ci: 1.11-3.16), physical inactivity (AOR = 4.07; 95% ci: 2.40-6.89), insufficient sleep (<7 hours/night; AOR = 1.87; 95% ci: 1.11-3.16), seasoning food before tasting (AOR = 3.25; 95% ci: 1.41-7.49), high-fat diet (AOR = 2.62; 95% ci: 1.46-4.68), and lack of knowledge of hereditary hypertension (AOR = 2.76; 95% ci: 1.22-6.24). Both non-modifiable (sex, disease duration, family history) and modifiable factors (exercise, sleep, diet) significantly affect blood pressure control. Targeted lifestyle interventions and systematic monitoring of high-risk groups are crucial to improving hypertension management and reducing cardiovascular risk.
