ABSTRACT
BACKGROUND:
Hypertension is one of the most common chronic diseases worldwide and is a major cause of cardiovascular disease, stroke, and renal failure. Treatment adherence and self-efficacy are critical for blood pressure control. This study aimed to investigate hypertension self-efficacy, medication adherence, and related factors among hypertensive patients aged 40–65 years attending Family Health Centers (FHCs).
METHODS:
The population of this cross-sectional study consisted of 88502 individuals aged 40–65 years living in Mezitli district, Mersin. The minimum sample size was calculated as 322 assuming a hypertension prevalence of 30%, 95% confidence interval, and ±5% margin of error. A total of 344 patients receiving antihypertensive treatment for at least one year were recruited from four randomly selected FHCs between July 1 and September 1, 2025. Data were collected using a structured questionnaire, anthropometric and blood pressure measurements, the Hypertension Self-Efficacy Scale, and the Medication Adherence Self-Efficacy Scale–Short Form (MASES-SF). Higher scores on both scales indicate higher self-efficacy and better medication adherence. Independent t-test, ANOVA, Pearson correlation, and multiple linear regression analyses were performed (p<0.05).
RESULTS:
The mean age was 57.97±6.09 years, and 59.3% were women. Mean systolic/diastolic blood pressure was 132.90±16.55/80.41±11.82 mmHg, and 74.4% had uncontrolled blood pressure. Mean self-efficacy score was 56.59±7.64 and mean MASES-SF score was 42.42±9.36. Higher self-efficacy was associated with female sex, regular medication use, having a blood pressure monitor, following a diet, receiving health education, and healthcare facility type, whereas higher body mass index was associated with lower self-efficacy (p<0.05). MASES-SF scores were significantly associated with marital status, healthcare facility type, regular medication use, duration of hypertension, and self-efficacy (p<0.05).
CONCLUSIONS:
Although self-efficacy and medication adherence were above average, uncontrolled blood pressure was common. Strengthening lifestyle interventions and health education at the primary care level may improve hypertension management.
