School based education programme to reduce salt intake in children and their families (School-EduSalt): cluster randomised controlled trial.

ABSTRACT:

Objective

To determine whether an education programme targeted at schoolchildren could lower salt intake in children and their families.

Design

Cluster randomised controlled trial, with schools randomly assigned to either the intervention or control group.

Setting

28 primary schools in urban Changzhi, northern China.

Participants

279 children in grade 5 of primary school, with mean age of 10.1; 553 adult family members (mean age 43.8).

Intervention

Children in the intervention group were educated on the harmful effects of salt and how to reduce salt intake within the schools' usual health education lessons. Children then delivered the salt reduction message to their families. The intervention lasted for one school term (about 3.5 months).
