Public ’ s Health Risk Awareness on Urban Air Pollution in Chinese Megacities: The Cases of Shanghai, Wuhan and Nanchang

View Article: PubMed Central - PubMed

ABSTRACT

This study assessed the public’s health risk awareness of urban air pollution triggered by three megacities in China, and the data are the responses from a sample size of 3868 megacity inhabitants from Shanghai, Nanchang and Wuhan. Descriptive analyses were used to summarize the respondents’ demographics, perceived health risks from air pollution and sources of health-related knowledge on urban air pollution. Chi-square tests were used to examine if participants’ demographics were associated with participant’s general attitudes towards current air quality and the three perceived highest health risks due to urban air pollution. We found low rate of satisfaction of current urban air quality as well as poor knowledge of air pollution related indicator. Participants’ gender, age and travel experience were found to be associated with the satisfaction of current air quality. The knowledge of air pollution related indicator was significantly affected by respondents’ education, monthly income, health status, and sites of study. As many as 46.23% of the participants expressed their feelings of anxiety when exposed to polluted air, especially females, older adults and those with poor health conditions. Most participants believed that coughs/colds, eye problems and skin allergies were the three highest health risks due to urban air pollution based on public education through television/radio, internet and newspaper/magazine. Further public health education is needed to improve public awareness of air pollution and its effects.

ijerph-13-00845-f001: Respondents’ perceived health risks from air pollution: the top three needing more attention.

Mentions: As shown in Figure 1, most participants responded that the main health risks due to air pollution are cough/cold (2662, 68.82%), eye problem (2436, 62.98%), skin allergies (1888, 48.81%) and difficulty breathing (1482, 38.31%). Table 7 illustrates the connection between respondents’ demographic factors and their beliefs about the three highest health risks due to urban air pollution. Chi-square test confirmed that females are more likely to believe cough/cold (χ2 = 5.368, p = 0.021), eye problem (χ2 = 38.963, p < 0.001) and skin allergies (χ2 = 8.672, p = 0.003) were the most common health risks related to air pollution. Linear trend chi-square test indicated that the older people believed cough/cold (χ2 = 44.377, p < 0.001) and eye problem (χ2 = 6.915, p = 0.009) were the most common health risks, while those with higher education level considered skin allergies (χ2 = 97.863, p < 0.001) was the most common health risk. Chi-square test also revealed that choosing cough/cold (2662, 68.82%), eye problem as the main health risks were significantly associated with respondents’ health status. It is interesting to find that different study sites had different opinions upon whether skin allergies were the main health risks due to air pollution.
