Because asthma and asthma-related symptoms constitutes a growing heallh problem around the world (Yu et al. 2011a, b), we undertook to investigate the disparities that exist between those living in urban vs. rural areas, in regard to the prevalence of asthma and asthma symptoms that they incur, hi particular, we evaluated the importance of geographic variations and their effects on asthma prevalence and morbidity among adults. In addition, we evaluated the possible causes of asthma morbidity between urban vs. mral residents. 

This article extends our earlier work (Yu et al. 2011a, b), in which we tried to determine the factors that affect the prevalence of asthma, allergy, and respiratory symptoms among adults, and whether rural/urban living has an effect on asthma prevalence. Investigating the differences that environmental risk factors pose to adults on prevalence of asthma and asthma-related symptoms in urban and rural locations may provide clues to the mechanisms by which asthma and asthma morbidity occur, and may also uncover needs that are currently unmet. 

In India, Gaur et al. (2006) found that the prevalence of asthma among the rural, urban city and urban-slum adult population of Delhi were 13.34%, 7.9% and 11.92%, respectively. The current prevalence of asthma was more pronounced if there was a history of family atopy, or where more vegetable debris, poor ventilation, air pollution and increased human density were present. There was also an association with increased smoking habits. However, no significant difference was noted in asthma prevalence between those living in urban and rural areas (Gaur et al. 2006). 

In New Zealand adults symptoms of asthma were generally found more commonly in urban areas compared with rural although some rural areas did show comparatively high prevalence values [51(111)]. 

Differences in Prevalence of Asthma and Asthma Morbidity Among Adult Smokers in Urban vs. Rural Areas... 

Different geographical and climatic properties (e.g., elevation, temperature, humidity) have a close relationship with asthma morbidity prevalence, such as allergic rhinitis among adults in urban and rural areas. Many geographic locations have climates that are favorable to indoor mold growth, for example, in tropical areas that routinely have high humidity.
