Cluster randomised controlled trial, with schools randomly assigned to either the intervention or control group. 28 primary schools in urban Changzhi, northern China. 279 children in grade 5 of primary school, with mean age of 10.1; 553 adult family members (mean age 43.8). 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). The primary outcome was the difference between the groups in the change in salt intake (as measured by 24 hour urinary sodium excretion) from baseline to the end of the trial. The secondary outcome was the difference between the two groups in the change in blood pressure. At baseline, the mean ...
