Abstract

Background

Childhood stunting (height-for-age z-score < −2 SD) remains a global developmental health burden. Traditional interventions centered on nutrition and infection have reached a bottleneck. Emerging evidence identifies chronic low-dose dietary environmental toxins as an independent, modifiable risk factor for early-life growth restriction.

Methods

This review synthesizes cohort studies, meta-analyses, and in vivo toxicological models published over the past decade to characterize exposures to mycotoxins, toxic heavy metals, and food-borne endocrine disruptors that are closely associated with stunting.

Results

Multi-layered mechanisms are elucidated, including environmental enteric dysfunction (EED), intestinal barrier disruption, persistent subclinical inflammation, GH-IGF-1 axis disturbance, gut microbiota dysbiosis, oxidative stress, and epigenetic alterations, which collectively impair linear growth. Critical surveillance gaps are identified, and integrated environment–nutrition–infection intervention strategies aligned with public health practice are proposed.

Conclusions

Dietary environmental toxins cause irreversible developmental deficits by damaging intestinal function and disrupting endocrine regulation. Strengthening developmental toxicology-oriented monitoring and source control will support precise prevention of early childhood stunting within the critical first 1000-day window.

期刊介绍： The journal Birth Defects Research publishes original research and reviews in areas related to the etiology of adverse developmental and reproductive outcome. In particular the journal is devoted to the publication of original scientific research that contributes to the understanding of the biology of embryonic development and the prenatal causative factors and mechanisms leading to adverse pregnancy outcomes, namely structural and functional birth defects, pregnancy loss, postnatal functional defects in the human population, and to the identification of prenatal factors and biological mechanisms that reduce these risks. Adverse reproductive and developmental outcomes may have genetic, environmental, nutritional or epigenetic causes. Accordingly, the journal Birth Defects Research takes an integrated, multidisciplinary approach in its organization and publication strategy. The journal Birth Defects Research contains separate sections for clinical and molecular teratology, developmental and reproductive toxicology, and reviews in developmental biology to acknowledge and accommodate the integrative nature of research in this field. Each section has a dedicated editor who is a leader in his/her field and who has full editorial authority in his/her area.
