The impact of environmental pollution on the physical health of middle-aged and older adults in China

Abstract

While several studies have demonstrated the negative impacts of environmental pollution on population health, in general, few studies have examined the potential differential effects on the health of middleaged and older populations, i.e. 45 years and older. Given the twin concerns of environmental pollution and population aging in China, this article employed a xed effects model to infer the impact of environmental pollution on public health with a particular focus on middle-aged and older adults. The analyses were based on data from the 2011-2018 waves of the CHARLS and pollutant data from prefecture-level cities. The results showed that environmental pollution signi cantly increased the risk of chronic diseases and negatively impacted the health of middle-aged and older adults. Environmental pollution had its greatest negative effect on the health of the elderly, women, urban residents and those with lower incomes than for their counterparts. We further found that the main channels of effect were through reduced physical exercise and an increase in depressive symptoms, and the pollution prevention actions alleviated the health deterioration of environmental pollution for the middle-aged and elderly. It is imperative for the government to urgently reinforce policy's enforcement to decrease air and water pollution, and enhance the ability to circumvent pollution for the lower socioeconomic groups.

Exploring the Modifying Role of GDP and Greenness on the Short Effect of Air Pollutants on Respiratory Hospitalization in Beijing

“…However, no significant associations were found between sex and GDP. Previous studies have found that older adults are more susceptible to the impacts of air pollution (Fan et al, 2022;Gaines et al, 2023;Gu et al, 2020;Kan et al, 2008), which may be a result of the vulnerability of respiratory function in the elderly. For stratified analysis by season, our study found that patients were more affected by pollutants except O 3 , PM 2.5 , and PM 10 during cold seasons.…”

Analysis of Air Pollution (SO2) at Some Point of Congestion in DKI Jakarta

“…Outdoor air pollution can spread from the home to urban areas, eventually becoming a global problem. Outdoor air pollution is the world's second most important air pollution problem, behind indoor air pollution, according to the Blacksmith Institute's World's Worst Polluted Places report from 2008 [12]. Pollution in the air can occur everywhere.…”

“…Lead, copper, zinc, iron chromium, and silica are all found in volcanic ash [11]. CO2 is one of the main causes of air pollution caused by volcanic eruptions, among the numerous gases generated by volcanic eruptions [12]. All volcanoes in the world are estimated to emit 0.13 -0.44 billion tons of CO2/per year [13].…”

Population aging challenge future mitigation of deaths attributable to PM2.5 pollution in China

“…The aging speed in China has exceeded that in most developed countries 29 . As population aging continues, DAPP is likely to subsequently increase 30 .…”
