E-Journal Bonus Article: Indoor Environmental Factors Related to the Prevalence of Asthma and Asthma-Related Symptoms Among Adults During Summer in Zunyi, Guizhou Province, China
Population-based estimates of asthma in adults in China during the summer season are lacking. A community-based survey was conducted among adults (N = 610) selected through simple random sampling across all inner-city areas of Zunyi in the Guizhou Province of China. Data on asthma and asthma-related symptoms and selected home environmental factors were collected using a modified European Community Respiratory Health Survey II questionnaire. The studied respondents recorded a prevalence rate of asthma and asthma-related symptoms in summer (7.5%) in Zunyi. Among a variety of risk factors, asthma in childhood, kitchen in the living room or bedroom, mixed fuel stove, cooking oil fumes, secondhand smoke, mold growth, and home furnishings were associated with increased risks of asthma and asthma-related symptoms. This study demonstrates the harmful effects of indoor air pollution from indoor environmental exposure on the lung function of adult residents in summer and emphasizes the need for public health efforts to decrease exposure to indoor environmental risk factors.
