Association between impaired lung function and carotid intima-media thickness in children

Area of Science:

• Pediatric Medicine
• Cardiovascular Health
• Pulmonology

Background:

• Cardiovascular disease (CVD) risk factors often track from childhood into adulthood.
• Obstructive lung diseases are increasingly recognized as potential contributors to CVD.
• Early life factors influencing both lung function and cardiovascular health require further investigation.

Purpose of the Study:

• To investigate the association between obstructive lung function impairment and subclinical cardiovascular changes in childhood.
• To determine if this association persists after controlling for established cardiovascular risk factors.

Main Methods:

• Cross-sectional study design.
• Assessment of lung function using spirometry to identify obstructive patterns.
• Measurement of carotid intima-media thickness (cIMT) as a marker of subclinical atherosclerosis.
• Statistical analysis accounting for potential confounders such as age, sex, socioeconomic status, and lifestyle factors.

Main Results:

• A significant association was found between obstructive lung function impairment and higher cIMT in children.
• This association remained evident even after adjusting for common cardiovascular risk factors.
• The findings highlight a potential link between early-life lung health and vascular development.

Conclusions:

• Obstructive lung function impairment in childhood is associated with subclinical atherosclerosis.
• This suggests a developmental pathway linking early lung disease to later cardiovascular disease.
• Interventions targeting lung health in early life may have long-term cardiovascular benefits.
