Respiratory diseases and cigarette smoking in a Hispanic population in New Mexico

Abstract

We have conducted a cross-sectional study of Hispanic residents of a community in New Mexico. A total of 2,111 subjects were recruited from 733 households; the overall participation rates were 68.1% for males and 78.9% for females. For all subjects, a standardized respiratory symptoms questionnaire was completed, spirometric testing was performed, and saliva and end-tidal breath samples were obtained. As in other populations, chronic respiratory symptoms were uncommon in children, and asthma was more prevalent in boys than in girls. In adults, physician-diagnosed chronic bronchitis and emphysema were less prevalent in this population than in a previously studied sample of non-Hispanic whites in New Mexico. Spirometric testing was confirmatory; less than 1% of the Hispanic males and females had chronic air-flow obstruction. The prevalence of cigarette usage in the Hispanics was comparable to data from non-Hispanic whites in New Mexico and from nationwide surveys. However, daily cigarette consumption by the Hispanics in this sample tended to be low, as found in previous studies in New Mexico and elsewhere.
