Community Blood Pressure Screening and Cardiovascular Risk Assessment in Croatia

NCT07670741 | Not Yet Recruiting

• 1 other identifier: OBSB-BP-2026-001
• Study Type: observational
• Target: 500

Brief Summary

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.

Outcome Measures

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.

  Baseline screening visit

Secondary Outcomes (7)

• Proportion of participants with previously known hypertension

  Baseline screening visit

• Proportion of participants receiving antihypertensive medication

Study Arms (1)

Community screening participants

Adults attending community-based public health blood pressure screening campaigns who provide informed consent and undergo questionnaire-based data collection and blood pressure measurement. Participants may optionally consent to short-term follow-up by telephone or email 1 to 3 months after the baseline screening visit.

Other: Blood pressure measurement and questionnaire-based data collection

Interventions

Blood pressure measurement and questionnaire-based data collection OTHER

Non-interventional measurement of blood pressure and pulse using validated blood pressure monitors, together with questionnaire-based collection of demographic characteristics, cardiovascular risk factors, medical history, medication use and lifestyle factors. No treatment is assigned, prescribed or modified by the research team.

Community screening participants

Eligibility Criteria

• Age: 18 Years+
• Sex: all
• Healthy Volunteers: Yes
• Age Groups: Adult (18-64), Older Adult (65+)
• Sampling Method: Non-Probability Sample

Study Population

Adults aged 18 years or older who voluntarily attend community-based public health blood pressure screening campaigns in Croatia and provide informed consent for participation. Participants may include individuals with or without previously diagnosed hypertension and with or without current antihypertensive treatment. The study population will be recruited from the general adult population attending public health screening activities.

You may qualify if:

• Age 18 years or older
• Voluntary attendance at a community-based public health blood pressure screening campaign
• Ability to understand the study information
• Signed informed consent for participation in the baseline observational study

You may not qualify if:

• Age under 18 years
• Inability or unwillingness to provide informed consent
• Incomplete baseline blood pressure data preventing assessment of the primary outcome
• Acute medical condition requiring immediate emergency evaluation before completion of study procedures, at the discretion of the research team
