Adherence to antihypertensive medications was 83.7%, with older age (OR 1.87), obesity (OR 1.76), and smoking (OR 2.62) significantly associated with non-adherence.

What factors are associated with antihypertensive medication non-adherence in Lebanese hypertensive adults?
In Lebanese hypertensive adults, older age, marital status, obesity, and smoking are associated with higher rates of non-adherence to antihypertensive medications.
Background: Poor adherence to antihypertensives is associated with negative outcome of the disease as well as loss of health-care resources. Addressing the epidemic of poor adherence requires identifying factors associated with this behaviour. The aim of this study is to describe adherence to antihypertensive medication among Lebanese hypertensive patients and to evaluate the association between socio-economic, patient- and conditions-related factors and non-adherence. Methods: A cross-sectional study was carried out on adherence to antihypertensive medications covering all governorates of Lebanon. This study was conducted between February 2018 and January 2019 on a random sample of 1497 hypertensive patients. A face-to-face questionnaire was used to assess adherence to antihypertensive medication and its determinants according to the five World Health Organization (WHO) main categories. Logistic regression analysis was performed to test the adjusted association between the multiple exposure factors, and drug adherence data were collected by trained interviewers. Results: Adherence to antihypertensive medications was reported by 1253 (83.7%) of the patients. After multivariate analysis, patients who tried to control their stress level (OR = 0.77, 95% CI 0.38– 0.95), those who had normal BP readings (OR =0.49, 95% CI 0.18– 0.97), and those who believed in the effectiveness of their treatment (OR = 0.31, 95% CI 0.14– 0.76) had a significantly lower chance to exhibit non-adherence to their treatment. However, older patients (OR= 1.87, 95% CI 1.23– 2.21), divorced/separated patients (OR= 2.14, 95% CI 1.31– 5.48), married (OR=1.96, 95% CI 1.27– 3.90), widowed (OR=2.11, 95% CI 1.62– 6.50), obese patients (OR = 1.76, 95% CI 1.21– 1.94), and patients who smoked hookah and cigarettes (OR = 2.62, 95% CI 1.17– 6.76) were more likely to exhibit non-adherence. Conclusion: Our study highlights the influence of factors such as old age, marital status, BMI and high level of emotional stress on non-adherence to medication in hypertensive patients. These determinants should be incorporated into adherence improving strategies. Keywords: non-adherence, antihypertensive medications, patient-related factors, condition-related factor, Lebanon
Abbas et al. (Tue,) conducted a cross-sectional in Hypertension (n=1,497). Antihypertensive medications was evaluated on Adherence to antihypertensive medications. Adherence to antihypertensive medications was 83.7%, with older age (OR 1.87), obesity (OR 1.76), and smoking (OR 2.62) significantly associated with non-adherence.
