Abstract

Childhood obesity and overweight rates are increasing in an exponential way. This type of diet-related health problem has consequences, not only at present but also for children’s future lives. For these reasons, it is very important to find a solution, which could be nutrition intervention programs. The main objective of this article is to investigate the effectiveness of nutrition intervention programs in children aged 3–12 around the world. We used SCOPUS, Web of Science, and PubMed databases to carry out this systematic review and we followed the PRISMA statement. Two authors conducted literature searches independently, finding a total of 138 articles. Finally, after a thorough screening, a total of 19 articles were selected for detailed analysis. The results show that, in general, nutrition intervention programs are effective in improving knowledge and behaviors about healthy habits, and, consequently, that the body mass index value is reduced. However, it is true that we found differences between the incomes of families and geographical areas. In conclusion, we encourage school centers to consider including these types of programs in their educational program and bring awareness of the importance of families too.

  • Although previous reviews have examined school-based nutrition interventions in children, most have focused on dietary intake, healthy eating behavior, or general nutrition outcomes rather than nutrition literacy as the primary target.

    “Although previous reviews have examined school-based nutrition interventions in children, most have focused on dietary intake, healthy eating behavior, or general nutrition outcomes rather than nutrition literacy as the primary target.”

    From Effects of school-based nutrition literacy Intervention on obesity prevention in school-age students: a systematic review and meta-analysis (2026) · cites this paper as [38]

    The Discussion and Introduction §1.4 describe this systematic review as examining school-based nutrition programs’ effects on children’s knowledge, eating behaviors, and other outcomes, rather than nutrition literacy as its primary target. The paper supports that characterization of itself, but it does not establish that most previous reviews had the same focus. (LLM, conf=0.84)

  • Changes in BMI may require a longer duration, greater intensity, and support from the family and school environment.

    “They may require a longer duration, greater intensity, and support from the family and school environment [22, 38].”

    From Effects of school-based nutrition literacy Intervention on obesity prevention in school-age students: a systematic review and meta-analysis (2026) · cites this paper as [38]

    The Discussion (page unavailable) reports mixed BMI results across nutrition interventions and says school environments and families are essential for promoting healthy habits. It does not say that BMI changes require longer duration or greater intensity, or specifically link family and school support to achieving BMI changes. (LLM, conf=0.82)

    Experimental — accuracy not yet measured
  • These findings are broadly consistent with earlier reviews of school-based nutrition interventions, which have generally shown clearer effects on knowledge and selected dietary outcomes than on BMI or other anthropometric measures.

    “These findings are broadly consistent with earlier reviews of school-based nutrition interventions, which have generally shown clearer effects on knowledge and selected dietary outcomes than on BMI or other anthropometric measures [38, 39].”
  • This is consistent with broader evidence showing that school-based programs can strengthen knowledge and some health behaviors, but changes in BMI are often less consistent.

    “This is consistent with broader evidence showing that school-based programs can strengthen knowledge and some health behaviors, but changes in BMI are often less consistent.”
  • Existing reviews have provided limited detail on how these interventions were designed and delivered, including their strategies, activity components, curriculum content, and implementation methods.

    “Existing reviews have also provided limited detail on how these interventions were designed and delivered, including their strategies, activity components, curriculum content, and implementation methods.”

    From Effects of school-based nutrition literacy Intervention on obesity prevention in school-age students: a systematic review and meta-analysis (2026) · cites this paper as [38]

    The Results (§3.2; page unavailable) describe this review’s own categories of intervention activities, and the Conclusions (§5; page unavailable) discuss limits to its geographic coverage. Neither section assesses whether existing reviews provide limited detail on intervention design, content, or implementation; searches for that assessment found no passage in our copy.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
