Rural Residence and Poverty Are Independent Risk Factors for Chronic Obstructive Pulmonary Disease in the United States

Abstract: Rationale: In developing countries, poor and rural areas have a high burden of chronic obstructive pulmonary disease (COPD), and environmental pollutants and indoor burning of biomass have been implicated as potential causal exposures. Less is known about the prevalence of COPD in the United States with respect to urban-rural distribution, poverty, and factors that uniquely contribute to COPD among never-smokers.Objectives: To understand the impact of urban-rural status, poverty, and other community factors on… Show more

“…The human exposure to air pollution is associated with increased mortality [18]. A high prevalence of COPD was reported in urban areas, especially in high-density areas [19][20][21]. The possible effects of urban built environments on COPD, therefore, may function through two ways: air quality and physical activity.…”

“…We adjusted for socioeconomic status and rural residence because people with HIV were disproportionately represented in low-income neighbourhoods and urban centres, and prior research has associated these variables with COPD. 31 We adjusted for comorbidity burden to account for differences in the underlying health of people with and without HIV.…”

“…Therefore, the associations with the mortality rates were more significant in Area 1 than in other areas. Because differences of population densities (especially in areas with more than 25 million people in Area 1) result in the accessibility of healthcare service as well as advanced technologies in public health [29][30][31], the mortality rates of circulatory and respiratory diseases in the Area 1 could be relatively lower than those in other areas.…”
