A preschool-wide intervention
The trial uses randomization by school: children from three preschools are assigned to the intervention group, while those from three others are assigned to the control group. The abstract specifies neither the total sample size nor the planned practices in the control group, two pieces of information needed to assess the comparison.
The program lasts one year. It combines health education and physical activity classes at school with dietary advice and educational materials shared with parents online. Parents’ knowledge, attitudes and practices are also assessed regularly.
The researchers therefore plan to address several aspects of the children’s environment rather than just their individual behaviors. This describes the rationale for the intervention, not proof of its superiority.
Body measurements and extended follow-up
Body measurements are planned at baseline, at six months and at twelve months, then during follow-up. Primary outcomes include between-group differences in body mass index, BMI scores and body fat percentage at the end of the intervention. Questionnaires will also document parents’ and children’s health behaviors.
According to the announced schedule, baseline assessments took place from March to June 2025, and the intervention was scheduled to end in June 2026. The protocol then provides for follow-up without intervention until June 2032, with annual surveys. This schedule alone does not establish which stages have actually been completed.
A research question, not yet an answer
The value of the project lies in comparing a program coordinated between school and family with a control group, then examining whether any changes persist. But no differences in BMI or body fat are reported in the abstract provided.
Even if a benefit were observed, this combined intervention would not necessarily allow the effect to be attributed separately to diet, physical activity or parental education. Its applicability in other school and family settings would also remain to be examined.
Limitations to keep in mind
Only the PubMed abstract was consulted, not the full text. It presents no results, does not specify the total sample size and provides little detail about the control group. Funding and conflicts of interest have not been verified.
What we can take away
This protocol asks a relevant question about obesity prevention in preschool. It does not yet demonstrate that the program works or that its effects last.
