Prevalence and Correlates of Airway Obstruction in a Community-Based Sample of AdultsProcedures: Conclusion

We are not aware of such studies being performed in Asia. To evaluate lung function and pulmonary disease based on spiromet-ric testing interpretations also requires comparisons with normal reference values that are specific to age, height, and sex. To avoid Read More

Prevalence and Correlates of Airway Obstruction in a Community-Based Sample of AdultsProcedures: Spirometric determinations

Deficiency of a1 antitrypsin, which is a well-known susceptibility factor for emphysema in Western countries, is rarely found in Korea, China, and Japan. No Z-type variant has been found in subjects in these latter three countries, or in Japanese-Americans in Read More

Prevalence and Correlates of Airway Obstruction in a Community-Based Sample of AdultsProcedures: Discussion

Table 4 presents factors that have an independent effect on airway obstruction. In addition to the adjustment for age and gender, adjustments also were made for the number of pack-years of smoking and alcohol intake. These latter two variables were Read More

Prevalence and Correlates of Airway Obstruction in a Community-Based Sample of AdultsProcedures: Airway obstruction

Ninety percent of these cases were mild in degree. None of the cases were very severe. The prevalence rates of airway obstruction within subgroups for each variable are shown in Table 3. The prevalence of airway obstruction was significantly higher Read More

Prevalence and Correlates of Airway Obstruction in a Community-Based Sample of AdultsProcedures: Statistical Analysis

Participants were classified as current smokers, former smokers, and never-smokers of cigarettes. Subjects were also classified by the number of pack-years of smoking (ie, 0, 0.1 to 9.9, 10.0 to 19.9, and > 20.0 pack-years). Body mass index (BMI) was Read More

Prevalence and Correlates of Airway Obstruction in a Community-Based Sample of AdultsProcedures: Pulmonary function tests

Sampling began by randomly selecting 4,700 households from 187,296 registered households. Among the 4,700 households, one age-eligible person was then randomly selected and interviewed by trained nursing students between June 1999 and April 2000. Among this group, 4,218 subjects completed Read More

Prevalence and Correlates of Airway Obstruction in a Community-Based Sample of Adults

Obstructive airway diseases, which include chronic bronchitis, emphysema, and asthma, are the fourth leading cause of death in the United States and constitute the only common cause of death that is increasing in prevalence. Among other diseases, the total public Read More

The current status of autotitrating continuous positive airway pressure systems in the management of obstructive sleep apnea: DISCUSSION (3)

Long-term CPAP compliance is related to the first-night experience with this treatment modality. The patients’ initial experiences with CPAP treatment may be a crucial factor in determining their subsequent regular use of CPAP, and any changes in the method of Read More

The current status of autotitrating continuous positive airway pressure systems in the management of obstructive sleep apnea: DISCUSSION (2)

APAP is promising for use in titration, with a number of comparative studies showing that treatment pressures estimated using this approach were either similar to or lower than those derived using manual titration; there were no adverse physiological effects. These Read More
