Chest
Clinical InvestigationsPrevalence of Reported Sleep Disturbances in a General Adult Population and their Relationship to Obstructive Airways Diseases
Section snippets
METHODS
Data were obtained from the 1984 and 1985 surveys of subjects participating in the Tucson Epidemiologic Study of Obstructive Airways Disease, a prospective longitudinal study of the natural history of obstructive lung disease which was begun in 1972. The study sample represents a random, stratified sample of the white, non-Mexican-American population of Tucson, Arizona. A detailed description of the methodology of population selection has been published.8 Since inception of the study, an
Description of General Population
Using our analysis criteria, survey data were available from 2,187 of 2,639 potential subjects, a questionnaire return rate of 82.9 percent. Of the remaining possible subjects, 57.3 percent were lost to follow-up, 29.8 percent refused to participate, and 12.9 percent were ill and unable to complete the questionnaire. The mean age of these individuals (47.1 ±22.4 yrs) was not different from the study population (49.1±19.7 yrs, p>0.05). Age distribution of the study population was as follows: 1)
DISCUSSION
This study demonstrates that complaints of sleep disturbances are common in the general adult population. The prevalence increases as a function of age, and is higher in women compared to men. Furthermore, complaints of sleep disturbance occur even more frequently in persons suffering from chronic obstructive airways disease.
Of the 2,639 subjects eligible for inclusion in our study population, we obtained a participation rate of over 80 percent. Age and gender comparisons between our study
