Evidence Base
The EDES tool family is grounded in decades of peer-reviewed research spanning endocrinology, reproductive toxicology, developmental biology, and environmental health. This page provides an overview of the evidence approach and a curated reference library of the most influential documents in the field.
What the Science Shows
Endocrine-disrupting chemicals (EDCs) are exogenous substances that interfere with hormonal regulation at every life stage — from foetal development to late adulthood. Over the past three decades, a large body of evidence has established that ubiquitous exposure to these chemicals is linked to rising rates of reproductive disorders, metabolic disease, neurodevelopmental impairment, thyroid dysfunction, and hormone-sensitive cancers.
Major institutional reviews — including the Endocrine Society’s two Scientific Statements, the WHO/UNEP State of the Science reports, and the 2024 Endocrine Society–IPEN Joint Report — converge on a consistent message: current levels of human exposure to EDCs are a significant public health concern, and clinical awareness remains critically low.
How the EDES Tools Use Evidence
EDES screening domains and flag levels are informed by a pragmatic synthesis of:
- Systematic reviews and meta-analyses
- Prospective cohort studies with exposure–outcome data
- Expert body assessments (WHO, UNEP, Endocrine Society, FIGO, AAP, ACOG)
- Regulatory agency risk assessments
- Established toxicological frameworks for endocrine disruption
EDES does not apply a formal evidence-grading system (such as GRADE). Flag levels reflect a pragmatic synthesis of evidence quality, consistency, and clinical relevance — supporting practical decision-making rather than making formal causal claims.
