About this trial
This is a prospective, observational, non-interventional study conducted during community-based public health blood pressure screening campaigns in Croatia. Adult participants who voluntarily attend public health actions will be invited to complete a short questionnaire on demographics, known cardiovascular risk factors, medical history and medication use. Blood pressure and pulse will be measured using validated blood pressure monitors. The study will assess the prevalence of elevated blood pressure, known and potentially undiagnosed hypertension, antihypertensive treatment patterns and cardiovascular risk factors. Participants may optionally consent to short-term follow-up by telephone or e-mail after 1 to 3 months to collect information on repeated blood pressure measurement, physician consultation, additional evaluation, new diagnosis of hypertension or medication change. The study does not include treatment allocation, prescribing or modification of therapy by the research team.

Trial outcomes
Primary outcomes
1
Prevalence of elevated blood pressure among adults attending community-based public health screening campaigns
The proportion of participants with an average systolic blood pressure of 140 millimeters of mercury (mmHg) or higher and/or an average diastolic blood pressure of 90 mmHg or higher at the baseline screening visit. Blood pressure will be calculated as the average of the last two available measurements. If three measurements are obtained, the average of the second and third measurements will be used. If only two measurements are available, the average of the first and second measurements will be used.
Time frame

1
Proportion of participants with previously known hypertension
Proportion of participants who self-report a previous diagnosis of arterial hypertension.
Time frame
Baseline screening visit2
Proportion of participants receiving antihypertensive medication
Proportion of participants who report current use of antihypertensive medication.
