Authors' conclusion

This study provided new evidence of air pollution and meteorological factors in children's cardiovascular health

Study context

Population
Children in the Southwest Health Children Cohort, Chongqing, Guizhou and Sichuan provinces, China, 2021–2025enrolled at baseline
Participants
2,029 children
Exposure
Exposure to PM2.5, temperature, extreme temperature events and relative humidity
Outcome
Cardiovascular structure and function by echocardiography

Main finding

As reported in the abstract

Cardiovascular structure and function remodelling · pregnancy to full exposure windows
  • PM2.5, temperature (TE), extreme temperature events (ETEs) and relative humidity (RH) exposure significantly associated with cardiovascular remodelling, including carotid intima thickening and decreased EF

Observational data: associations, not effects.

Further findings

Cardiovascular remodelling, by family income and BP (subgroups)

Associations more pronounced in children from low-income families or with elevated BP

PM2.5 × ETEs interaction

PM2.5 synergistically interacted with ETEs to promote abnormal cardiovascular remodelling

Biomarkers

Hexosylceramide, phosphoenolpyruvate, triacylglyceride and myosin light chain 3 identified as important biomarkers linking environmental hazards with abnormal remodelling
