Raises a question worth testing. It does not answer one.
This is a narrative review proposing that PM2.5 exposure, obstructive sleep apnea, and obesity share common biological pathways including systemic inflammation, oxidative stress, neuroendocrine dysregulation, and gut microbiota alterations. The work synthesizes existing epidemiological and mechanistic evidence to frame a conceptual model and identify knowledge gaps, but does not present primary evidence testing these integrated mechanisms.
Narrative review. Urban populations chronically exposed to adverse environmental conditions; focus on obesity and obstructive sleep apnea.
Chronic PM2.5 exposure has been related to higher BMI, central fat deposition, metabolic syndrome, and increased OSA risk and severity Obesity is identified as the main modifiable risk factor for OSA Intermittent hypoxia and sleep fragmentation can aggravate hormonal, inflammatory, and metabolic disturbances involved in weight gain
Safety was not reported in the material analysed. Check the source before drawing any conclusion about harm.
This review frames a mechanistic hypothesis linking environmental air pollution, sleep disruption, and metabolic dysfunction that may guide future research design. Clinicians should view this as a conceptual scaffold for understanding patient risk factors rather than evidence for specific interventions or causation.

What is missing. This record has no reported figures. That is a gap in the analysis, not a judgement about the study.
Obesity and obstructive sleep apnea (OSA) are highly prevalent and interconnected conditions that contribute to the global burden of chronic non-communicable diseases. Fine particulate matter (PM 2.5 ), a major component of air pollution, has emerged as a relevant factor linked to metabolic dysfunction and sleep disturbances. Chronic exposure to PM 2.5 has been related to higher body mass index (BMI), central fat deposition, metabolic syndrome, and increased OSA risk and severity. Obesity remains the main modifiable risk factor for OSA, whereas intermittent hypoxia and sleep fragmentation can aggravate hormonal, inflammatory, and metabolic disturbances involved in weight gain. PM 2.5 exposure and OSA overlap through pathways involving systemic inflammation, oxidative stress, neuroendocrine dysregulation, and gut microbiota alterations. These converging mechanisms highlight the potential role of environmental pollution and sleep disruption in obesity pathophysiology, particularly in urban populations chronically exposed to adverse environmental conditions. This review synthesizes current epidemiological and mechanistic evidence, identifies important knowledge gaps, and proposes shared biological pathways that may inform future research on the interplay among PM 2.5 exposure, OSA, and obesity.
