Hypertension is a risk factor for renal, cardiovascular and cerebrovascular diseases. It is responsible for a large proportion of overall morbidity and mortality every year. Hypertension-mediated organ damage is largely not reversible. For these reasons, prevention has primary importance: sensibilization of population on hypertension-related consequences is essential for therapeutic adherence and reduction of unhealthy lifestyle behaviour. This study aimed to evaluate awareness about hypertension among community pharmacies customers. A questionnaire about hypertension was collected by 2731 customers from 94 community pharmacies in North West Italy, during a hypertension screening program. Hypertension awareness was unsatisfactory in a large proportion of the sample, with only 15% of subjects having an overall good level of knowledge. Furthermore, lower awareness was associated to higher blood pressure values (132/79 ± 19/11 mmHg vs 128/78 ± 18/10 mmHg, p < 0.001) and subjects resulted hypertensive or uncontrolled despite antihypertensive therapy, presented worse questionnaire scores (4.7 ± 1.9 vs 4.9 ± 2.0, p = 0.03). Knowledge about hypertension is largely unsatisfactory among population. Community pharmacies may play as a setting for health education and hypertension screening. •Health education among population is essential in reducing hypertension related morbidity and mortality.•Knowledge about hypertension is often unsatisfactory among population.•Poor hypertension knowledge is associated with hypertension underdiagnosis and poor blood pressure control.•Community pharmacies can represent a non-medical sanitary setting for health education and hypertension screening.
