Title: A School-based Education Programme to Reduce Salt Intake in Children and Their Families (School-EduSalt)
Brief Summary: The study is to test whether an education programme targeted at school children can lower salt intake in children and their families. In this study, the investigators will educate children on how to reduce salt intake, and the investigators will empower children by asking them to deliver the salt reduction message home to their families, particularly children need to persuade the person who does the cooking for the whole family to cut down on the amount of salt used during food preparations. The study will involve children aged about 11 years, and their parents and grandparents in Northern China.
