- Propensity to migrate and willingness to pay were relatively high in Wuhan.
- Study subjects were selected from hospital and community population respectively.
- Parents’ propensity to migrate was significantly affected by income among two populations.
- Personal responsibility was related with willingness to pay among two populations.
Objective: To understand parents’ propensity to migrate and willingness to pay with respect to outdoor air pollution, and to explore related affecting factors.
Methods: This study used a convenience sample and subjects were collected from a community in Wuchang District and Children’s Hospital of Wuhan, respectively. A designed questionnaire was used for this study. Univariable and multivariable logistic regression models were applied to analyze the relationship between parents’ individual and familial characteristics and related behavioral intensions to air quality improvement. Statistical analysis was done with SAS 9.1.
Results: The questionnaire was completed by 865 subjects (response rate = 86.5%). The number of people with migrant intent was 150(36.4%) from hospital group, and 139(30.7%) from community group. In the hospital group, subjects with higher knowledge of air quality (OR = 6.268, p < 0.05) and higher average annual household income (AAHI), which was equal or more than 50,000 Yuan (OR = 2.045, p < 0.01), were found to be more intent to migrate. AAHI (OR = 1.939, p < 0.05) was also the affecting factor in the community group correspondingly. Those willing to pay for air quality improvement included 297 people (72.1%) from the hospital group and 333 people (73.5%) from the community group, and affecting factors was the public responsibility for air quality improvement (hospital group: OR = 3.380, p < 0.01; community group: OR = 4.436, p < 0.01).
Conclusions: This study indicated high tendency of propensity to migrate for avoiding poor air condition and willingness to pay to improve air quality in Wuhan. Local governments should pay more attention to parents’ knowledge of air pollution and attitudes towards government management of air quality, especially those willing to migrate.
