In several human populations, exposure to EDCs frequently co-occur with insufficient iodine intake, impairing thyroid function, and reducing the capacity to adapt to environmental changes. This brief review summarizes the current state of knowledge on the mechanisms through which EDCs and iodine deficiency can interfere with virtually every component of TH homeostasis.

Exposures can occur through occupational exposure, but there is increasing evidence for residential exposure in non-agricultural workers.

Although BMAT is consistently inversely associated with BMD, evidence linking BMAT to fractures is heterogeneous. Cross-sectional and longitudinal studies have indicated the limited added predictive value of BMAT over established clinical risk factors and BMD.

Current evidence suggests that bisphenols, phthalates, perfluoroalkyl compounds, and polychlorinated biphenyls are linked to modest but measurable changes in thyroid hormone balance, often influenced by body weight. Adipose tissue may serve as a reservoir for lipophilic EDCs, sustaining internal exposure, and exacerbating metabolic dysregulation. However, the extent to which these associations reflect causal mechanisms remains unclear. Future research should prioritize longitudinal and mechanistic studies to clarify directionality, identify vulnerable populations, and inform precision-based approaches for exposure mitigation.</div></div>","PeriodicalId":52218,"journal":{"name":"Current Opinion in Endocrine and Metabolic Research","volume":"42 ","pages":"Article 100592"},"PeriodicalIF":0.0,"publicationDate":"2026-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145750226","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
