This study aims to examine the feasibility and effectiveness of written behavioural persuasion techniques intervention to encourage treatment initiation and follow-up for hypertension management among the untreated hypertension population of the SEACO cohort.
Each household is given a unique identifier called house_id in the SEACO database. The randomisation will be computer-generated according to their house_id with a ratio of 1:1. During the house visit, participants' blood pressure will be taken three times, and the final reading will be the average of the second and third readings. Participants will be assessed based on the inclusion and exclusion criteria, i.e., age 35 years and above, blood pressure reading and reported not being diagnosed with or treated for hypertension. At the end of the house visit, all participants will receive a standard referral leaflet, and participants randomised to the intervention group will receive an additional written behavioural persuasion leaflet.
6,689 studies on the registry are indexed under Hypertension; 965 are open to participants now.
This study's enrollment of 893 is above the median of 90 across 4,995 interventional studies indexed under Hypertension.
