Ambient particulate-phase polycyclic aromatic hydrocarbon mixtures and gastrointestinal disease prevalence in China: a population-based cross-sectional study

Key Points

• This study aims to investigate the relationship between ambient particulate-phase polycyclic aromatic hydrocarbons and gastrointestinal disease prevalence among older adults in China.
• Cross-sectional study design
• Analysis of gastrointestinal disease prevalence
• Assessment of ambient particulate-phase PAH levels
• Population focused on middle-aged and older adults in China
• Increased prevalence of gastrointestinal diseases correlated with higher PAH levels
• Specific PAH mixtures showed notable associations with disease prevalence
• Findings indicate potential public health implications related to air quality
