Air Pollution and Metabolic Syndrome

A study conducted by Dr. Ikenna C. Eze of the Swiss Tropical and Public Health Institute analyzed the connection between air pollutants and Metabolic syndrome. Metabolic syndrome is, ” is a cluster of conditions- increased blood pressure, high blood sugar, excess body fat around the waist, and abnormal cholesterol or triglyceride levels — that occur together, increasing your risk of heart disease, stroke and diabetes” (Mayo Clinic). Both metabolic syndrome and air pollutants are associated with increasing inflammation and cardiovascular disease risk, but little research has been done to see how the two influence each other. 


The study found that after short term experimental air pollutant diesel exposure there was a 72% increase in symptoms associated with the World Health Organization’s definition of metabolic syndrome. Associations were stronger among those who had impaired glucose homeostasis and less strongly with subjects that had excess fat tissue surrounding their organs (visceral adiposity). Diesel exposure also correlated with an increase in blood clots (thrombocytes) and a decrease in blood plasma (haemoconcentration). Cardiovascular issues were associated to experimental exposure to ultrafine particle air pollution exposure.
