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 misclassification due to ethnic disparities, reference values also need to be race-specific.’ This kind of baseline study for pulmonary function testing in regions like Korea, and throughout Asia, need to be conducted to help improve the early detection of obstructive airway disease.

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

Prevalence and Correlates of Airway Obstruction in a Community-Based Sample of AdultsProcedures: Spirometric determinationsDeficiency 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 Hawaii as well.- Ethnic differences in the morbidity and mortality from obstructive airway disease also have been described. Individuals from the United Kingdom are more susceptible to airway obstruction than are those from eastern Europe and North America. Mexican-American women tend to have less of a chance of dying from COPD than non-Hispanic white women (OR, 0.36; 95% CI, 0.18 to 0.72). canadian health mall

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

Even after excluding subjects aged 18 to 24 years, the prevalence continues to be low in the Korean sample (10.5%). In a comparison of the prevalence for each age-sex group by ATS criteria to the same criteria in the Po Delta, the Korean rates remain substantially lower.

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

Prevalence and Correlates of Airway Obstruction in a Community-Based Sample of AdultsProcedures: DiscussionTable 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 included as covariates since they showed significant relationships with airway obstruction in models that included adjustments for age. Based on these adjusted models, the odds of disease were 3.2 times greater (95% confidence interval [CI], 1.7 to 6.2) in subjects who had smoked for a 20 pack-years vs those who had never smoked.

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 in men (17%) than in women (5.6%; p < 0.001). Eighteen percent of subjects aged > 45 years had airway obstruction, whereas the prevalence for individuals < 45 years of age was only 3.8% (p < 0.001).

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

Prevalence and Correlates of Airway Obstruction in a Community-Based Sample of AdultsProcedures: Statistical AnalysisParticipants 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 calculated as weight (in kilograms) divided by height (in meters) squared. Average alcohol consumption was categorized by the number of drinks per week (ie, 0, 1 to 7, 8 to 21, and > 22 drinks per week). Here, one drink is equivalent to the intake of 12.5 g ethyl alcohol.

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 the interview and received a physical examination.

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

Prevalence and Correlates of Airway Obstruction in a Community-Based Sample of AdultsObstructive 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 health burden of obstructive airway diseases is expected to rank fifth by 2020.2 The recognition of obstructive airway disease as a public health problem, however, has failed to keep pace with its increasing impact on health-care resources.

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 titration must include compliance as a long-term outcome. buy ortho tri-cyclen online
Since the conclusion of the present review, further randomized crossover studies have reported similar findings, with APAP giving similar outcomes to CPAP in different patient groups. These included patients with a high within-night variability in pressure requirements, and patients with difficult-to-treat OSA (where the comparator was bilevel CPAP).

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

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 findings, however, must be qualified by the exclusion of patients with various serious medical conditions in a number of studies, and the use of attended titration in most cases. In a number of patients, interventions were necessary during attended APAP titration to stop mask leaks, adjust mask fit or provide supplemental oxygen for nocturnal hypoxemia.
