Background: Hypertension is an important worldwide public health challenge. It has changed from a trivial cause of death and disability to one of the global burden diseases. The biggest obstacle for inadequate therapeutic control of blood pressure is meagre knowledge, poor attitude, inadequate treatment practices and lack of adherence towards antihypertensive treatment. The present study was planned to assess the awareness of hypertension on various aspects and to evaluate treatment adherence in hypertensive patients.

Methods: This cross-sectional study was conducted on 100 hypertensive patients of both genders visiting medicine OPD at HIMS, Dehradun over a period of six months. A structured and validated questionnaire was used to assess the knowledge, attitude and practice (KAP) among patients. Morisky 8-Item Medication Adherence Questionnaire was used to assess the adherence towards antihypertensive medications. For statistical analysis Chi square test was used.

Results: Out of the 100 patients the median KAP scores were 6(5),5(1) and 10(4) respectively. Most of the subjects had high median scores on attitude but majority of the subjects had low knowledge and self-care practice scores. Further Analysis of data revealed that a poor score in self-care practice was significantly associated to the gender(p<0.004) as well as to the level of education(p<0.006).Only 40% patients were adherent to their medication, this result was statistically associated with the level of education (p<0.00001).

Conclusions: Hypertensive patients in our community have good attitude but poor knowledge and self-care practices towards management of hypertension. Patients were also found to be non-adherent to their antihypertensive medications.
