Why the study?

Population-wide blood pressure reduction is a proposed cardiovascular prevention strategy, but the effectiveness of frontline health worker task sharing remained to be evaluated.

Does a task-sharing strategy involving frontline health workers delivering structured lifestyle modification reduce population-level blood pressure in India?

Comparison

Frontline health worker-delivered structured lifestyle modification vs control

Design

Cluster randomized controlled trial

Follow-up

18 months

Overview

Does not support frontline worker-led lifestyle intervention for population BP control; challenges scalability assumptions and leaves open questions for optimized strategies.

Structured PICO

Does a task-sharing strategy involving frontline health workers delivering structured lifestyle modification reduce population-level blood pressure in India?

P
Population
Participants from 47 village clusters across 4 states in India (n=13,813 at baseline; 6,663 in control clusters, 7,150 in intervention clusters).
I
Intervention
Custom-made and structured lifestyle modification intervention delivered by frontline health workers (Anganwadi Workers and Accredited Social Health Activists) over 18 months.
C
Comparator
Control clusters receiving standard care without the structured lifestyle modification intervention.
O
Outcome
Population average adjusted mean difference in difference in systolic blood pressure at 18 months.surrogate

A task-sharing lifestyle modification intervention delivered by minimally trained frontline health workers did not significantly reduce population-level systolic blood pressure in India.
