Healthy School mEAls With Less Salt：an Action to Reduce Salt Intake in School Meals for Children in Rural China

16,000 participantsStarted 2023-10

Plain-language summary

This study aims to assess the impact of the HEALS-Child action project on children's health in rural China. The goal of the project is to evaluate the effectiveness, feasibility, safety and cost-effectiveness of two salt reduction strategies: replacing usual salt with salt substitute in school meals, and replacing bowls with trays in school cafeteria. The study has two parts: the main study evaluates the salt substitute intervention, and the ancillary study evaluates the tray intervention. In the main study, over 16000 students from around 320 elementary or junior high school in rural China will be cluster-randomized into the two groups: 1. Salt substitute 2.usual salt. The primary outcome in the main study will be the change in systolic blood pressure. In the ancillary study, over 500 students from 10 elementary or junior high school will be cluster-randomized into the two groups: 1. meal trays 2.bowls. The primary outcome in the ancillary study will be the change in spot urine sodium. The interventions will last over 1 years. To evaluate the impact of interventions, 50 students were randomly selected from each school.

Questions worth asking your doctor

Bring these to your next appointment. They're a starting point for a shared conversation — not a sign you qualify or a recommendation to enrol.

1Based on my diagnosis and history, is this trial worth exploring for me — or is there a standard treatment we should try first?
2What does this trial's phase tell us about how much is already known about its safety and benefit?
3What would taking part actually involve for me — visits, tests, time, and travel?
4What are the known and possible risks or side effects I should weigh, and how would they be monitored?
5If this trial isn't the right fit, what other options or trials would you suggest I look into?

Generated to help you prepare — always confirm anything about your own eligibility and care with the study team and your doctor.

Questions for the trial coordinator

The trial coordinator is the person who runs the study day to day. These cover the practical side — logistics, costs, and what taking part would actually mean for your life. The study team confirms whether you meet the criteria; these are questions to ask, not a sign you qualify.

1What does taking part actually involve week to week — how many visits, where, and how long does each one take?
2What costs are covered by the study, and what might I have to pay for myself, including travel, parking, or time off work?
3What happens during screening, and what happens if the study team confirms I don't meet the criteria after those tests?
4Who pays for the scans, blood work, and other tests the trial requires — the study, my insurance, or me?
5How will being in the trial affect my regular care, and will my own doctor stay informed and involved?
6Can I leave the trial at any point if I change my mind, and what would happen to my care if I do?

A starting point for the conversation — always confirm anything about your own eligibility, costs, and care with the study team and your doctor.
