Faith leaders take on high blood pressure in massive tanzanian study
NCT ID NCT05416372
First seen Jun 26, 2026 · Last updated Jul 23, 2026 · Updated 3 times
Summary
This study tests whether training Christian and Muslim religious leaders to teach their communities about blood pressure can lower average blood pressure. Researchers will compare communities where leaders receive training to those where they do not. About 24,000 adults aged 35 and older across 20 communities in Tanzania will take part.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- Religious Engagement in Health Intervention (behavioral program)
- What this could lead to
- If successful, this could show that training religious leaders is an effective way to lower blood pressure across entire communities.
- What could go wrong
- This is a behavioral study, not a drug trial. Results depend on community participation and may not apply to other settings. Blood pressure changes may be small.
