Study Population
All households in the three jurisdictions with a telephone connected and the number listed in the current version of the electronic white pages were eligible for selection in the sample. Samples were drawn separately for each state. The target number of interviews for each state was 2,500. A stratified sampling technique was used with the distribution of these interviews planned: n = 900 in the metropolitan area, n = 800 in rural areas, and n = 800 in remote areas. The minimum sample size of
Results
From the available sample of 10,080, 7,619 interviews were completed (participation rate, 74.8%), with 834 people reporting current doctor-diagnosed asthma (11.2%). The demographic characteristics of people with and without asthma are shown in Table 1. People with asthma were significantly more likely to also report other chronic conditions. Table 2 shows odds ratios from logistic regression analysis for the association between asthma and individual chronic conditions, adjusted for age and
Discussion
In a large population-based sample, we found that selected major chronic conditions occur more frequently in people with asthma, particularly in older age groups. The coexistence of these conditions is associated with greater functional impairment in terms of activity limitation and quality of life than if they are found alone. Again, the effect was seen more clearly in older age groups. Although arthritis was the most common comorbid condition with asthma, the greatest decrements in quality of

Current Limitations and Recent Advances in the Management of Asthma
2023, Disease-a-MonthDiabetes Mellitus Is Associated with Worse Outcome in Patients Hospitalized for Asthma
2021, Journal of Allergy and Clinical Immunology: In PracticeCitation Excerpt :Once considered “a rare coincidence” in the 1970s,35 DM is now a common and significant comorbidity of asthma. The prevalence of DM in patients with asthma ranges from 5% to 16%,36,37 and was as high as 28% in our study. From an individual patient level, mechanistic studies on how DM and asthma interact are urgently needed.
Asthma Morbidity, Comorbidities, and Modifiable Factors Among Older Adults
2018, Journal of Allergy and Clinical Immunology: In PracticeCitation Excerpt :Depression has been associated with the presence of asthma and worse asthma control among older adults; these results indicate that asthma-related hospitalizations and ED/UCV are additional concerns for older adults with concomitant asthma and depression.1,7,26 Prior studies have reported heart disease and diabetes to be more prevalent among adults with asthma compared with adult controls,1,26-28 but older adults comprised a minority in these study populations and asthma-related hospitalizations or ED/UCV were not examined.27,28 Current evidence suggests that obesity is a risk factor for the development of asthma and can affect asthma control,29,30 but very little is known about the relationship between obesity and asthma in older adults.31
