Study investigates air pollution's effect on catastrophic health expenditure in older adults, suggesting regulatory needs.

Key Points

The study aims to explore the relationship between air pollution and catastrophic health expenditure (CHE) among middle-aged and older adults in China.
Utilized China Health and Retirement Longitudinal Study data matched with PM 2.5 and meteorological data.
Included 24004 participants aged 45 and above and defined CHE as out-of-pocket health expenditures exceeding 40% of non-food expenditure.
Employed a random effects logit model and instrumental variable estimation to assess the impact of PM 2.5 on CHE.
PM 2.5 exposure significantly raises the likelihood of CHE among the participants.
Increased PM 2.5 exposure exacerbates CHE by raising direct health costs and reducing labor supply.
Heterogeneity analysis shows that urban residents and those older than 65 years with lower education are more affected by PM 2.5 exposure.
