Eating-window trial reported blood-pressure reductions in young people with elevated readings
A school-based trial found blood-pressure changes, but incomplete follow-up and unclear effect-size comparisons limit how confidently the results can be interpreted.
Based on the published abstract. The full paper may contain additional methods, results and limitations.
The 30-second takeaway
Both eating-window groups had lower systolic blood pressure after the intervention, and the earlier-final-meal group had a diastolic-pressure change that differed significantly from control. The abstract does not establish that a fixed last mealtime is superior to a flexible one. Substantial loss to follow-up makes the findings harder to interpret.
Only 59.4% of participants completed follow-up at 12 months. The abstract does not clearly identify the comparator for each numerical blood-pressure estimate, and it gives no safety results despite listing safety as an aim.
What researchers found
Diastolic blood-pressure change
At 12 months, change in the earlier-final-meal group differed from unrestricted controls (p = 0.006). A clear between-group magnitude was not given.
How the trial handled grouping
Researchers assigned school classes to eating schedules and analyzed participants in their original groups. The statistical models accounted for class-level grouping, and a sensitivity analysis examined the influence of missing data.
Who the findings concern
The study concerns young people who already had elevated blood pressure. It provides evidence about that clinical subgroup, without establishing a suitable eating schedule for children generally or resolving safety questions.
