Key result
Among 259 hypertensive patients, 55% had poor blood pressure control and 58% had poor medication adherence, with specific medication beliefs and illness perceptions acting as significant predictors.
Why the study?
The study was conducted to assess medication adherence, illness perception, and beliefs about medications, and to examine their association with blood pressure control in hypertensive patients.

Are illness perceptions and beliefs about medication associated with medication adherence and blood pressure control in hypertensive patients?
Beliefs about medications and illness perception are significant predictors of poor medication adherence and blood pressure control in hypertensive patients.
Low adherence in this Egyptian cohort leaves open whether targeting perceptions improves BP control; prospective studies needed.
Objectives: To assess medication adherence, illness perception, beliefs about medications,to examine their association with blood pressure control among patients in ZagazigUniversity hospital. Method: A cross-sectional study was held on 259 hypertensivepatients attending Internal Medicine outpatient clinic, Zagazig University hospital. Theyunderwent complete history taking, comprehensive clinical examination comprisingassessing of their blood pressure. Then the patients completed Modified Morisky scale-8(MMS-8), brief illness perception (BIPQ) and belief about medication (BMQ)questionnaires. Results: About 55% and 58% reported poor blood pressure control andmedication adherence respectively. There is statistically significant relation between bloodpressure control and patients’ sex, education, occupation, medication number, IPR causaldomain, family history of hypertension-induced mortality, BIPR score, general overuse,specific necessity, specific concern, and adherence. There were significant relationsbetween adherence and patients’ sex, social class, marital status, education, occupation,duration, medications number, family history of hypertension-induced mortality, IPQcausal item, general overuse, specific concern, and necessity. Significant risk factors ofboth poor control and medication adherence included specific necessity ≤ 9, generaloveruse >15 and using 3 to 4 drugs. Male, not working/unskilled increased risk of poorcontrol. Not working/unskilled workers and skilled worker/free business, disease duration>5 years, perceiving lifestyle and hereditary as hypertension causes, having secondaryeducation or higher were significant protectors from poor adherence. Conclusion: Beliefabout medications and illness perception were among the predictors of poor medicationadherence and blood pressure control as well. Both can affect blood pressure controldirectly or indirectly via influencing adherence.
