This cross-sectional study aimed to explore factors predicting medication adherence among patients with essential hypertension. The subjects consisted of 225 patients with essential hypertension, aged eighteen-year-olds or above, who were. self- medicating for at least six months, and treated at an outpatient department in a tertiary hospital in Bangkok. Data were collected by questionnaires and analyzed using descriptive statistics and logistic regression analysis.
The results revealed that of thesd respondents, 60% were female, the mean age was 68 (SD = 10.23), 80% of essential hypertension indicated medication adherence. Income sufficiency, health coverage, medication regimen complexity, the severity of the disease, and health literacy were co-pre predict medication adherence among patients with essential hypertension at 29.6% (R² = .296). Income sufficiency, medication regimen complexity and health literacy were able to predict medication adherence with statistical significance (OR = 3.86, 95% CI= 1.31 – 11.35, OR = 2.86, 95% CI = 1.28 - 6.38 and OR= 5.62, 95% CI = 1.61 – 19.43), respectively.
