| Summary: | The prevalence of obesity has reached epidemic proportions worldwide, posing a significant public health concern due to its association with various chronic diseases and healthcare costs. In addition to traditional risk factors such as diet and physical activity, emerging evidence suggests that environmental pollutants, termed obesogens, may contribute to the obesity epidemic. Obesogens are endocrine-disrupting chemicals (EDCs) that can alter lipid homeostasis, promote adipogenesis, and disrupt metabolic regulation, leading to increased adiposity and obesity risk. This review explores available data from human studies published in the last decade, along with the mechanisms underlying obesogenic action, including their effects on adipocyte differentiation, adipose tissue development, and metabolic regulation. Overall, 75 studies were analyzed. Early-life exposure during critical developmental windows has been shown to increase obesity risk later in life, potentially through epigenetic modifications and transgenerational effects. Epidemiological studies provide evidence of associations between prenatal or early-life exposure and increased obesity risk in offspring. Additionally, study found more consistent associations between exposure to some EDCs (including phthalates, parabens, and bisphenols) and obesity or metabolic outcomes in children and women, while results for other chemicals (i.e. PFAS and organochlorine pesticides) were more heterogeneous, especially in adolescents and adults. Key findings indicate consistent associations between phthalate exposure and obesity in children, with mixed results for adults. Future research should focus on elucidating the full spectrum of obesogens, their mechanisms of action, and their implications for obesity risk across generations. This knowledge will inform preventive strategies and public health interventions aimed at addressing the obesity epidemic and its associated health burden. |
