Key Takeaway
Consider that endocrine-disrupting chemicals may contribute to obesity, but evidence strength and consistency remain uncertain.

This narrative mini-review synthesizes evidence from human studies investigating the impact of endocrine-disrupting chemicals (EDCs) on metabolic health. The review focuses on conditions related to obesity, including adipogenic differentiation, adiposity, body weight, BMI, and abdominal obesity. No specific medications or controlled interventions were evaluated, as the exposure was to environmental chemicals rather than therapeutic agents.

Main results indicate that adipogenic differentiation is affected by a wide variety of EDCs, though specific effect sizes and absolute numbers were not reported. Similarly, adiposity is associated with chemical exposure, but precise statistical data, p-values, or confidence intervals are not provided in this narrative synthesis. The review notes that the strength and consistency of these effects are still not entirely understood across the available literature.

Safety and tolerability data were not reported for this review. Key limitations include the uncertainty regarding how effects may differ based on the specific EDCs involved, the timing of exposure, and the sex of the individuals. Consequently, the review does not establish definitive causal links but rather reports associations between exposure and adiposity.

The practice relevance of this evidence suggests that public health interventions should prioritize identifying and regulating EDCs. Clinicians should recognize that while EDCs may contribute to adipogenesis and metabolic dysfunction, the current evidence is observational and incomplete. Further research is needed to clarify the mechanisms and variability of these effects before specific clinical recommendations can be made.

IntroductionObesity is increasingly recognized as a multifactorial disease influenced by environmental exposures, including endocrine-disrupting chemicals (EDCs). These substances interfere with hormonal signaling and may contribute to adipogenesis and metabolic dysfunction.MethodsThis narrative mini-review drew on epidemiological, experimental, and clinical research and examined the most recent literature on the role of EDCs in adipogenesis. It focuses on the mechanisms of action.ResultsStudies report that a wide variety of EDCs affect adipogenic differentiation through pathways mediated by nuclear receptors (PPARγ/RXR) and through broader endocrine disruptions involving estrogen-, glucocorticoid-, and thyroid-related pathways. Adiposity, including body weight, BMI, and abdominal obesity, is associated with chemical exposure, according to clinical data from human studies. Since they may differ based on the EDCs, the timing of exposure, and sex, the strength and consistency of the effects are still not entirely understood.ConclusionsOne important environmental factor in the development of obesity is EDCs. Public health interventions should prioritize identifying and regulating them.
