(ORDO NEWS) — Researchers from King’s College London have found that air pollution can increase the risk of hypertension in teenagers.
Exposure to air pollutants is associated with an increased risk of cardiovascular disease, hospitalizations and death.
Rapidly growing adolescents may be particularly susceptible to the long-term effects of air pollutant exposure, but most previous research has focused on adults.
For the new analysis, the researchers used data on 3,284 teenagers from London.
They looked at the effects of two of the most common air pollutants: nitrogen dioxide and particles smaller than 2.5 microns in diameter (PM2.5).
The researchers found that exposure to nitrogen dioxide was associated with lower systolic blood pressure, and exposure to PM2.5 was associated with higher systolic blood pressure.
These associations were stronger in girls than in boys.
No relationship was observed between air pollutants and diastolic blood pressure. The authors’ conclusions showed the need for further research.
